The other day I was listening to a podcast and letting my mind wander. The podcast was Radio National’s All in the Mind and the topic up for discussion was daydreaming and dementia.
Do you daydream? I hope you do!
Daydreaming has a bad rap, but as it turns out, we should not be so hard on ourselves when we wander off. Daydreaming is a very healthy brain activity and while it may get you into trouble if you are zoned out when someone (like your boss) is trying to get your attention, the fact that you CAN daydream, especially if you are older, is an indication of a healthier brain.
“people living with frontotemporal dementia – a form of younger-onset dementia – lose the ability to daydream. ”
We let our minds wander a lot! Up to 50% of waking time. Daydreaming allows us to explore the unknown, practice conversations and confrontations, escape from reality, plan and problem solve. I know I write my best stories when I am out running! Pity I don’t remember them when I get back! 🙂
People with frontotemporal dementia lose this ability and remain rooted in the present and stimulus bound.
“They become increasingly focused on what is immediately in front of them, such as watching TV, listening to a piece of music, or eating food.”
They lose the ability to create their own internal world.
I have a particular interest in dementia and have done lots of reading on the topic and even an online course through the University of Tasmania. I am concerned about developing dementia (and arthritis!). Being an old chook (a female over 55), I am getting dangerously close to dementia being a real thing in my life. While I can’t change the genetic road map I have been given or do much about getting older, I can do my best to look after the modifiable factors that influence dementia risk.
Let your mind wander!
It turns out that the sorts of things we have been told to do to maintain heart health will also look after the brain and the joints because they reduce inflammation. Inflammation is a big contributor to both these conditions. We need to ensure that we keep our blood pressure at a healthy level, stay active and keep moving, maintain a healthy weight, eat a healthy diet which is based mainly in plants, never smoke and drink alcohol cautiously. Easy!
Just by the by, if you are interested in things to do with the brain and psychology, the All in the Mind podcast is fabulous. I must say I have a bit of girl-crush on Lynne Malcolm, the show’s presenter!
(As this is published I’ll be in an aeroplane somewhere returning home after my epic Scottish adventure)
I don’t remember what I was dreaming about, but I was in one of those stages of sleep where my mind was buzzing, and even though I was sure I was awake, in reality, I was still unconscious. One of my dream-characters reminded me that this month marked the 10th anniversary of me leaving the marital home. Me walking out and into my own little bedsit, so we could “have some space to think things through”.
I took an independent step. I was proactive.
Another dream-character piped up with the idea that it must be getting close to 10 years since I raised my voice in anger. Ten years since I have screamed with murderous rage and ill intent… At anyone.
I am not saying I haven’t been angry or upset since that time – of course, I have, but since then I have never been in a frame of mind that was so filled with venom and hate.
So much has happened in those ten years. So many good things! I still lament the 10 years I wasted before that, in trying to stitch together something that was shredded and beyond repair. Why did we do that to ourselves? It’s not only me who wasted time. It wasn’t just me who lost good years in the technical “prime” of our lives.
That is all inconsequential now. Now is what counts, and where my head is NOW. If you have been reading this blog, you will know I have been rejoicing in the discovery of a new found creativity that has been hidden below the surface. It took a while for it to bubble to the top and make its way through the cracks, but it’s here – NOW.
I am happier although I am still restless. Something else is out there waiting to be discovered. And before all my friends get excited, it’s not another partner!
One thing I have learned is that I don’t need to be in a partnership. I have good friends, a loving family and an intentionally busy life filled with interesting pursuits and being coupled won’t add to this. Not NOW.
If you are in a broken relationship, it probably won’t get better. Leave! Don’t stay for the children’s sake. The kids will do better in a settled home. They don’t need to feel or hear the hate that seethes out of your skin. If there is violence, they don’t need that either.
Leave!
Don’t waste 10 years. Don’t waste five!
Take the plunge.
It might be cold when you first get in, but you’ll warm up!
I don’t miss much about my marriage, but the one thing I really do miss is singing! My ex was a musician. He played guitar and drums. While never achieving any fame and spending way more than he ever earned, it was a very satisfying hobby for him and by default, for me as well. Sitting around the kitchen or on the lounge after work and on weekends he would play his Maton acoustic and sing. Most times I would join in with him. I am no virtuoso, but I could hold a tune and used to really enjoy these times.
I guess if we were singing, we weren’t fighting!
High School Teachers Band! (photo by David Croft)
The repertoire was fairly broad but consisted of mostly “middle of the road” rock and folk music. There was plenty of Paul Kelly, Cold Chisel, Dire Straits as well as Bob Dylan (which incidentally I didn’t join in on).
I especially enjoyed the family singalongs with his brothers and sisters. These were always happy nights that went into the wee hours.
Once upon a time, I had the guts to get up and sing in front of people!
Since I have been on my own, my opportunity to sing ad hoc has completely vanished, and now when I try and sing along in the car or in my kitchen, my voice is weak and becomes hoarse very quickly. I begin to splutter and cough. I guess it’s like anything, it takes practise and training. My “singing” muscles are no longer in good condition. Sadly, I can’t remember the last time I actually sang with other people!
Singing is something I will have to find a way to bring back into my life. I didn’t include it as one of my 60 for 60 items. That was an oversight and something I will need to remedy.
I am not sure I have the level of commitment needed for a choir while I am still trapped in the day job, so I’ll be on the lookout for a Grannies’ garage band! 😆
I wrote about other aspects of music in my life in a post last year. You can read it here.
Last week I wrote about the nutritional value (or not) of coffee, this week the focus is on economic factors. This is a simplified analysis and not meant to be an economic treatise. There are no doubt, lots of angles I have not considered.
Microeconomics – your budget.
Café coffee:
As a point of reference, I am going to use my regular order of a skim milk regular sized cappuccino as the “standard” purchase. You can pay anywhere from $A3:50 – $A6:00 depending on size and location so I will use a cost of $4 per cup.
If you buy one cappuccino every day, you are going to spend $4 x 365 = $1460 per capita per annum.
So maybe you only buy coffee on the days you work. Using a 5 day work week and four weeks annual leave that’s $4 x 240 = $960.
Let’s say your working life is around 40 years; you’ll end up spending between $40,000 – $60,000 on coffee! If you’re living as a couple, that could be $80-120,000 over your lifetimes.
SHIT that’s scary money!
That’s three years of mortgage payments! Is it worth it?
Do-it-yourself coffee – instant.
Ok, so you’ve decided you can’t do without coffee. Can you save money by making your own?
Well yes!
A 200 g jar of instant coffee will set you back around $13 from Woollies and will make around 100 cups of coffee. Plus there’s milk and sugar or sweetener if you use it. I am not going to try and factor those in here.
If we stick to the one cup per day, every day of the year you will spend $47 per annum.
Over your work life and not allowing for inflation; $1900.
BOOM! An instant saving of $38K per person. But you aren’t going to switch to Moccona because we have all become coffee snobs who want “proper” coffee from the trendy cafe! And in reality, you’ll probably drink both the made at home/work and the cup(s) from the cafe.
Maybe you can buy a coffee machine and save money that way?
Do-it-yourself – coffee machine.
This calculation presents a few problems. It’s a bit of a “how-long-is-a-piece-of-string” argument. Just typing “coffee makers” into Google; gives you machines ranging from $3000 to $59. If you spend $3000 on a coffee machine, it will take you 2 years to make your money back, and I bet you won’t!
Why?
Because even if you have a fancy coffee maker, you’ll still buy coffee from the cute little cafe near work! You know you will!
Using a pod machine will save you money too, BUT you’ll have to deal with the environmental cost of all those plastic or metal pods. AND you’ll still buy coffee from the cute little cafe near work! You know you will!
Of course, you could grind your own coffee too and use a plunger or lots of other methods which would be cheaper than cafe coffee so you could potentially spend much less than that estimate of $60,000 over a working lifetime.
I’m not here to tell you how to spend your money or tell you if you can afford that or not. You’ll have to decide that for yourself, but you may have not given it much thought. I think the main point is that coffee is a luxury. While some of you will argue that it is essential, it’s not. Not like food or shelter. The money you spend on it is discretionary.
Macroeconomics – the global economy
The Production Side of Coffee
Coffee is derived from two main species Coffea arabica and C. Robusta. It has only been in widespread usage as a beverage for around 500 years. It is thought to have originated in Ethiopia where it was domesticated before being distributed widely. The now huge South American crop originated from the seeds of a single plant taken from the Amsterdam Botanical Gardens.
The ten biggest coffee growing nations are Brazi, Vietnam, Columbia, Indonesia, Peru, Ethiopia, Mexico, India, Guatemala and Uganda. The countries that consume the most coffee are (in order) United States, Germany, Japan, Italy and France.
I think you can see how things are going to pan out here. There is an imbalance between the economic power of the people who grow coffee and the people who drink coffee.
Poor people grow it, rich(er) people drink it.
The price of coffee is controlled by the commodity markets in New York and London, a long way from the growers. It is the second most traded commodity after crude oil. I have no idea how these commodity markets work, but I’m sure that the people on the floor yelling and shouting at each other aren’t thinking about whether a grower can feed his family on what he will be paid.
According to the documentary Black Gold (2014), Ethiopian farmers are paid around 65c per kilo. It costs them 90c to produce one kilo of coffee. (huh???) There are up to six steps in the chain from grower to consumer with each step adding to the price. The coffee part of your daily cup is only worth around 3 cents. While this data is now five years old, the principle remains the same. The growers are not given a fair price for their labour and have to endure significant hardship so you can be perky.
I recommend you download the Black Gold documentary. You can watch the trailer here or buy/rent the full version.
Watch it, then try and drink your coffee with a clear conscience!
The consumption side of coffee
I live in the small city of Wollongong which has a population of just under 300,000. A Google search of cafes in Wollongong throws up 8 pages of results. The people at Wollongong Council told me there are X cafes. (I’m waiting on the council to get back to me with that number but it’s lots! ) That’s a lot of cafes and a lot of jobs. Multiply that by towns in Australia, and then the world. There must be a bazillion million million dollars sloshing around in coffee.
People who work in or own cafes aren’t exactly rolling in cash either. In Australia, there are more small traders selling coffee compared to big chains like Starbucks or Tim Hortons. Many cafe workers are students earning the minimum wage. Then there are the roasters, the distributors, the drivers who deliver the coffee, the importers, the cup manufacturers, the barista trainers, the espresso machine makers, etc. etc. etc.!
According to IBIS World, the cafe and coffee shop industry in Australia alone is worth $10Bn with a growth rate of 2.2%. 139,091 people are employed by 20375 businesses. (I don’t think this includes all the ancillary services listed above.) Contrary to what I was thinking, this represents only a tiny proportion of the total value of Australian business which was estimated to be around $1.7 trillion in 2016.
So, perhaps the Australian economy wouldn’t fall over if we all stopped buying coffee, but it would be sleepier and grumpier!
Can you be a more ethical coffee consumer?
Yes – to an extent.
Buy your coffee from a small business rather than big chains or multinationals. That way your money goes to pay for a family’s expenses and not making faceless corporations bigger.
You can look at helping finance a grower directly through an organisation such as Kiva which provides micro-loans directly to people in need. You can read about Kiva here.
Somewhere between me being 45 and nearly 60, Wollongong’s nightlife has been through a metamorphosis. At one time, Wollongong had a reputation for being violent. Rolling brawls spilled out of places like the Glasshouse onto the streets and kept people like me at home. We didn’t feel comfortable sharing noisy venues with barely-clad chicky babes and young men whose sole goal was to get “maggoted”. My friends and I stayed at home and had civilised dinner parties, sometimes venturing out to the popular Little Prince* only to be disappointed because we couldn’t find a seat.
(*I’ll review the Littel Prince in another post)
More recently and I’m reticent to use the word “suddenly” because I’m sure it has not been sudden, there has been a torrent of small bars setting up shop. These places have style, the music is quieter, the seats more comfortable and the lighting more subdued.
It’s not so much a case of Wollongong changing from an ugly caterpillar into a butterfly, because some those rowdier places are still open for business. Rather, new classier blood has moved into the neighbourhood offering more choice to a broader range of patrons. In fact, we’re spoiled for choice at the moment!
My friends and I are not looking for somewhere to “hook up” or meet a date. We want a place where we can feel comfortable alone or with a group of friends for a chat. We enjoy good food and are fussy in our choice of drinks. We want background music that stays in the background and excellent amenities in terms of toilets, glassware and seating.
So which small bars are a good match for Old Chooks?
In the interests of research, I decided to hit the streets and review the boutique and small bar scene, systematically and scientifically. Armed with an online survey, I enlisted the help of some dedicated Old Chooks (Diane and Karen) to critically evaluate what was on offer.
So far, we have checked out six small bars over two nights in Febraury and March 2019. We will bravely venture out again to check out more bars in the coming months. Tough work but someone has to do it!
Methodology
I must say we approached our task with enthusiasm, and frankly, I think we got a little overexcited. It was funny how having a purpose changed the dynamics of a night out, transforming it from a simple social get-together to a serious mission. It also meant we were more observant than we would have been otherwise. The methodology is simple. We each pick a bar, then work out the most efficient walking route between them. Once at the bar, we carefully check the food and drinks menu and the toilets. These are the deal breakers in our view! We try to engage the bar staff in conversation without giving our game away. We order a drink each and some food to share and then after an hour or so move onto the next bar.
Three bars, three drinks, three snacks.
In that hour, we are busy on our phones filling in the survey and discussing the lighting, the ambience, the crowd and the facilities. The survey is comprehensive, and each question is given a score. The scores are then added up to provide an overall rating. There are a few inherent biases in the method. The first bar on the list is reviewed early in the night, and it may not have yet reached its peak ambience. Another factor is that the third bar is considered after 2 drinks. Hopefully, we are not such cheap drunks that our focus is too frayed!
The reviews
Juniper Bar
121 Keira Street, Wollongong
Juniper was our first review, and we started there at about 7:30 PM. There were plenty of available tables. The crowd was made up of three male/female couples and a group of eight 30-40-year-old females. Four men walked in, looked around and walked out. Perhaps it was a bit girly for their taste? The concrete walls were sponged with pastel tones, and there was no other decoration. The wooden tables were garnished with small candles and a bit of greenery in a recycled jar. The concrete floor and walls created a noisy vibe, and the music was too loud for easy conversation. There was a definite need for some soft surfaces to act as noise dampeners. The bar itself had a charming backlit display which was very interesting.
Juniper, as the name suggests, is a gin bar. There was an extensive selection of gin but little else besides. The printed menu was very informative and gave good descriptions of the gin varietals. They offered gin-based cocktails as well as straight nips and various tonic mixers. The drinks ranged in price from $11 – $19. The food menu was minimal (a choice a three) and there was no vegetarian option. We chose the drinks plate: a platter of cheese and meats with very crunchy toasted bread ~ $25. The two wait staff were friendly.
BEST: Excellent subdued lighting. The bar was nicely lit and looked very pretty.
WORST: Noise levels and food choices.
Black Cockatoo.
88 Kembla Street, Wollongong (behind the Creamies gelato shop)
I felt like a secret agent entering the Black Cockatoo with its hidden entry off an ice cream parlour. I wish you needed to give a secret handshake! Once inside the dark interior was reminiscent of an American bar. Booths lined the walls with a few standing tables as well as seats at the bar. It’s a small venue with a capacity for around 30. A large painted mural of a cockatoo and a few band posters were the only decorations. Still, it had a nice ambience tending to retro. Two 20-something men were serving. They were very casually dressed in long shorts and t-shirts. The food menu was again minimal and this time consisted of packet chips, sausage rolls and cheese and spinach pies. Don’t come here looking for a meal! The drinks menu was small and limited to canned beers, a few imported draft beers and a small selection of wine. Drink prices were reasonable, ranging from $6 up to $15.
When we arrived at 8:30, we were the only ones there for a few minutes, and the boys were happy to chat while not being obtrusive. With a very late licence, this would be the place for a late night meet-up, not an Old Chooks night out. There was one toilet which had no hand towels although it was tidy in other respects. The music was great, probably meant to be retro but it was all our era!
BEST: The secret agent feel and the music.
WORST: Food. Although, to be honest, if you were here late at night, a sausage roll might be perfect!
Births and Deaths.
2/74 Kembla St, Wollongong
Births and Deaths has had a fair bit of cash thrown at it. The black walls frame the $6000 -worth of Italian tiles that back the bar. There is one long re-manufactured stone table in the middle of the room which would comfortably seat 30 and cafe style seating around outside of the room as well as a few stools at the bar. The bar was half full, with an interesting mix of people. B&D offered table service, a nice touch. We chatted at length to one of the owners, Jared. He explained his philosophy which focused on sustainability. He said they reused as much as possible. The straws were metal, the coasters, washable fabric. The kitchen ran on the concept of minimising waste with the beetroot and pumpkin scraps leftover from the tasting plates used to make syrup for drinks. According to Jared of Births and Deaths, my friends and I are part of the targeted demographic boutique bars in Wollongong are looking for. Cashed up and older. Young folk, you see “pre-drink” and are stingy about buying food. Old Chooks like us, on the other hand, go out early, buy more expensive drinks and order lots of food. He is also part owner of the Howling Wolf and works in partnership with Cavaeu (a hatted restaurant nearby). He was very accommodating and chatty and talked to us about his plans and the issues of getting a licence and permission to operate.
B&D is also a gin bar but has a broader selection of wine and beers than Juniper. The food was unique, and while not vegetarian, was mostly plant-based. We tried a pumpkin plate which included morsels of pumpkin cooked a few different ways as well as some cheese and tomato toasties.
BEST: The food and the staff.
WORST: The toilet while not unisex, was not very private and it was easy to “disturb” the privacy of other patrons.
Night Parrot
69 Crown St, Wollongong
The Night Parrot was our first stop on the second research night. The technical hitches we had with the online survey (Diane’s phone going flat and Karen using the wrong form) had been solved, so we were ready to go! A fourth researcher, Tanya, joined us. There were five other groups of people and seating was not a problem. The other patrons were well dressed and included a few couples. The decor was dark and classy with one wall lined with highly varnished wood panels. The remaining walls and ceiling were painted black and gave the place a cave-like feel. The Night Parrot is a wine bar and features a walk-in wine cabinet which takes up one of the on-street windows. The busy kitchen was visible from the bar and added significantly to the atmosphere with steam wafting up from the stoves. There was seating at the bar as well as open tables and three padded “booths” which seated three comfortably with the fourth at the other side of the table. There was table service, and it took a little longer than expected to give our orders. I had decided to do Feb-Fast and was not drinking alcohol, and while the others were quickly served their wine, I had to ask a second time for my soda water. The volume of the music created a pleasant, unobtrusive feel and allowed for easy conversation. The lighting was on the dark side. This along with the dark walls, gave it a cozy atmosphere. The bar area was brightly lit. The one toilet cubicle was unisex. It was large and spacious with plenty of extra rolls of paper, gentle soap and a blower dryer. The decor was eclectic with a large suspended branch acting as a chandelier.
A small selection of food was on offer. I had the dumplings which were tasty and good value at four pieces for $14. The wine selection was a mix of local and imported wines and over a wide price range. Both Diane and Tanya ($22) were pleased with their grenaches, one local ($14) one imported ($22).
BEST: The decor and the wine selection;
WORST: We thought that with the way the seating was arranged, it would be tough to feel comfortable as a solo visitor.
Moominn
68 Crown St, Wollongong
Moominn is a quirky, warm, cozy place. It reminded me of someone’s Grandma’s lounge room. There is a mixture of seating from a few lounge chairs around a fireplace to kitchen tables with old lino chairs. Some seating at the bar is also available. There are all sorts of bits and pieces hanging from the ceiling. Baskets, flowers, light fittings, bottles, umbrellas etc. The walls are entirely covered with mismatched pictures which scream out OP SHOP find. A large blackboard shows the specials as well as a few witty quotes. They had flavoursome zero alcohol beer, and I would have had another if we were staying longer.
The others all had the same red wine and seemed satisfied with their choice. The drinks were served in very simple, practical glasses. The barkeeper was friendly and offered advice on what beer they had when I asked for no alcohol. The food was OK. I found it a bit oily although the others enjoyed the mix of deep fried mushrooms, cauliflower and cheese bites. A second plate with bread and meatballs was very garlicky. The two dishes were $50 in total. They were small servings, and this seemed expensive to me. The single well-lit toilet is out back through the kitchen. Quaint sayings are painted on the walls, and the jumbled, over-decorated theme continues here.
The music, while pleasant, was too loud. There was a good crowd of around 20 in attendance, We originally sat at the bar and swooped on a table when it was vacated. The partons were a very mixed group with a good spattering of older people. It would be easy to visit Mooninn as a solo traveller with the lounge chairs near the fire being cozy and private.
BEST: Quirky fun feel
WORST: Noise levels
The Throsby
2/88 Kembla St, Wollongong
The Throsby is one of the more established small bars in Wollongong and has been open for several years. I had been there before. The waitress seemed to be annoyed when we walked in, and her face showed it. It looked like we had crashed a private party. It was only 10:10 PM. The first thing she said was the kitchen has closed. Most of the tables were empty, and there were two other groups. A group of four young men at the table nearest the door and a group of six young people at the bar.
The decor is muted and sophisticated. You could describe it as Scandi with blond timber and fine lines. A petite arrangement of flowers/leaves was on each table. The light fittings were chic woven timber. Their glassware was elegant, and I had a tasty pink grapefruit-soda water mix. The music was bland but at a reasonable volume. The one toilet was a bit messy and smelly. It might have been OK at the beginning of the night but needed a clean at this time.
Karen and Tanya both commented that the wine was a bit acidic. We could not comment on the food as we did not see a menu. Although the vibe was quite pleasant, we did not interact with the wait staff at all beyond ordering our drinks. We did not score the Throsby well, and we perhaps were over critical because of our less than enthusiastic greeting.
BEST: decor and glassware:
WORST: Reception on arrival. If you’re not open for business, close the door!
And the winner (so far) is…
The graph below shows our overall scores for the six bars visited to date. Births and Deaths has come out as a clear winner for many reasons. Jared was a star. Friendly, knowledgeable and willing to spend time chatting with us telling us about his philosophy. This made all the difference.
In modern Australian culture and elsewhere, coffee has reached near god-like status. It’s big business and for some, a life force.
According to many t-shirts, it is imbued with amazing properties.
It keeps some people alive: “I can’t function without my morning coffee.”
It can restore lost speech: “No Coffee – No Talkie.”
It can even prevent murder: Coffee helps me maintain my “never killed anyone streak.”
A few of the hundreds of coffee themed t-shirts available online
The science of coffee.
To be precise, it’s the caffeine (and other methylxanthines: see the diagram below) present in coffee that does the trick. Caffeine is classed as a heterocyclic nitrogen compound. Its structure is very similar to two of the important building blocks of DNA, adenine and guanine.
My brother hand drew those diagram!
It is water soluble, a critical property because if it weren’t soluble, you wouldn’t be able to drink it in the first place! Caffeine has a melting point of 237°C, another important factor because it doesn’t evaporate away under normal processing conditions. It is an alkaline, white powder when in pure form. Chemically, it’s nothing like cocaine or other stimulants except that it also contains a bunch of carbon atoms joined in a complicated ring shape with a few nitrogens and oxygens and double bonds thrown in.
Caffeine and its biological precursors have been reported in over 160 species of plant. It is found in coffee beans, tea leaves, cocoa, cola nuts, guarana, and plants of the Ilex species such as maté.
Because caffeine is water soluble, the way a coffee beverage is prepared has a significant effect on the amount of caffeine in a cup. It’s all about maximising the solubility. Increasing the temperature of the water, increasing the surface area and making the beans more porous will increase the caffeine content in your daily cup. Hence we roast the coffee beans to make them porous (and tasty) then we grind them to massively increase the surface area before we soak them in hot water. Voila!
The caffeine dose can vary from around 50mg up to 150 mg per 250 mL cup.
The pharmacological effects of caffeine
In plants, caffeine is thought to act as an insect deterrent due to its extreme bitterness. Humans found out about its about stimulating effects a long time ago and have harvested and then cultivated caffeine-rich plants for millennia.
Caffeine does indeed have many well researched pharmacological effects, but most cherished is its ability to perk you up. In 1983 I wrote:
“Caffeine is a stimulant and considered the most widely used of self-administered drugs in the form of coffee, tea and cola beverages. Most people have been exposed to the stimulating effect of these substances and the majority of the population consumes pharmacological doses [~100mg] of the drug at regular intervals throughout the day.”
The list of effects is long.
Dilation of the blood vessels
Increased respiration
Increased urine output
Increased gastric secretions
Relaxation of smooth muscle tissue
Reduced the blood supply to the brain
Stimulation of the central nervous system
Increased motor activity and response to sensory stimuli (aka makes you more alert!)
Elevation of plasma free fatty acids and glucose. Some research shows that it can assist in weight loss by increasing fat metabolism while exercising.
Caffeine is absorbed rapidly and appears in the blood within 5 minutes of consumption. In most people, it takes about 3.5 hours to clear the blood and be excreted in urine, but in some individuals (like me!) who lack sufficient metabolic enzymes, it can remain active for much longer. Because it is cleared so quickly from the blood, it does not accumulate in the body.
Too much caffeine can lead to headache, tremors, abnormal heart rhythms and irritation of the gut. In addition, we all know about the effect caffeine can have on sleep. Chronic overconsumption of caffeine results in symptoms that are indistinguishable from anxiety neurosis. It would take about 10 g of pure caffeine to kill you.
Nutritional value of coffee
A cup of black coffee has no nutritional value. It has no fat, no carbohydrates, no protein, no vitamins and only minuscule traces of magnesium. We have to agree the only reason we drink it is because of the caffeine. BUT who drinks coffee black? Not many people! It’s all the stuff we add to coffee that boosts its nutritional status. The data in the table below is taken from Gloria Jean’s website and is fairly typical of the data available.
The energy value of a whole milk cappuccino is going to cost you between 484 kJ (116 kcal) – 725 kJ (173 kcal) depending on size. For skim milk, you are looking at about half that. Soy milk is a little higher than skim milk for energy. The milk is going to provide you with protein, fat, calcium and some lactose. If you add sugar, you can add another 64 kJ (16 kcal) per teaspoon. A large cappuccino could, therefore, represent a fair proportion of your daily energy intake and must be considered if you are avoiding weight gain. If you go for something fancy, like a full cream caramel latte, you’re talking around 1000 kJ (220 kcal) or the same amount of energy in 3 eggs!
So, is coffee good for you?
My thesis is too old to give me good advice in regards to the overall health effects of caffeine and coffee. So a search of the interwebs turns up some interesting information.
The European Food Safety Authority (EFSA) in a review on the Safety of Caffeine concluded that moderate caffeine consumption, of around 400mg caffeine per day (the equivalent of up to 5 cups of coffee), can be enjoyed as part of a healthy balanced diet and an active lifestyle. Pregnant and breastfeeding women are advised to limit their caffeine intake to 200mg per day.
It even goes so far as to say that caffeine consumption is associated with a reduced rate of mortality. Is this from the coffee itself or from the social aspect of coffee? That’s a whole other kettle of fish. Once again however we are talking about caffeine not the coffee beverage of choice. Sure, caffeine might have no ill effects, but if you pile in the sugar and cream, that’s a different story entirely!
In my own case, if I have more than one cappuccino a day, I end up with a belly full of gas. I know from anecdotal experience I am not the only one who suffers this consequence. As stated above, caffeine stimulates the production of gastric juices which speeds up digestion, milk contains lactose which challenges many adults at the best of times and with the relaxation of smooth muscle, which incidentally is the type of muscle in your intestines… well … well, you know how it’s going to end!
I guess you need to consider whether your personal circumstances can cope with the increased energy consumption of milk based coffee beverages. If it can’t, you might want to consider black coffee or even a splash of milk in a cup of International Roast!
I sat down with the intention of writing a short piece about coffee and the effect it has on our waistlines and wallets. As I started doing some research and looking at various websites on how many calories there are in various coffee beverages, how much coffee is drunk daily in Australia etc.; it got me thinking.
Where does this coffee come from? How much do we as a nation, spend? What about worldwide? Are there long term health benefits or does it cause health issues? Is it sustainable? All those disposable coffee cups have got to end up somewhere. Can all those corner cafes be supported? Where would you go to meet friends/on a first date if you don’t want to drink coffee and it wasn’t beer o’clock yet? What about tea? Would we solve all/any the issues if we switched to drinking only tea? Is coffee even worth drinking? Now come on, be honest, do you even LIKE the taste of coffee?
My swirling mind became caught in a spiral of ideas worse than being trapped in a Pinterest Vortex! I decided it was way bigger than one post could handle and it needed to be a series of blog posts. This post serves as an introduction and sets the scene. I will follow it up with another 5 posts over the next few months. (It might even grow from that number!)
Part 1 will be about the Waistline Effect: here I will explore the pharmacological, health and dietary effects of caffeine.
Part 2 looks at the economic effects of coffee on a micro (your household budget) and macro (the global economy) scale.
Part 3 investigates the environmental impact: are we burying our cities under a mountain of disposable cups. Are Keep Cups going to save the day? Are we causing rural poverty in those countries that supply our daily fix?
Part 4: What are the cultural differences in coffee drinking. Is Australian the only place you can buy a decent skim cap? I need your help here. Have you ever been able to buy a decent coffee in another country?
Part 5: Tea v Coffee. Does it make a difference? Plus anything else I haven’t been able to fit into the other posts.
I feel like a bit of a coffee expert, not because I drink lots, but because way back in the day when I was completing my undergraduate degree in Food Technology, I wrote my Honours Thesis on “Caffeine and its Derivatives in Australian Foods and Beverages”.
With nothing more than my trusty portable typewriter and correction tape, I banged out one hundred and thirty pages of meta-analysis and lab results about methylxanthines, the chemical group which includes caffeine and other similar compounds. While some of it is outdated, it remains a good starting point.
On a personal note, I’m a tea drinker. I limit the amount of coffee I buy from a cafe to around 1 – 2 cups a week if that. This decision is based on three factors.
Kilojoule intake. I drink skim milk cappucinos. That’s around 120 kcal or nearly 500 kJ which is approximately 8% of my target daily intake.
Lactose intake – I think I must be a little lactose intolerant because milk-based coffee drinks make my belly grumble unpredictably with embarrassing consequences!
I am stingy. $4 a cup every day that’s nearly $1500 a year!
I hope you’ll enjoy these posts and let me know your favourite cafe in the comments below!
As I was looking for articles about older women doing amazing things, I came across this story in the Telegraph. Not exactly what I was searching for, but thought-provoking none-the-less.
The report concentrates on the shift in attitudes of women who, 20 years ago, may have been described as middle-aged. It highlights how older women are generally taking on a more positive approach to aging and being more confident to express a style other than “grandma”.
This section particularly resonated with me and sent me on the search for more information.
Everywhere we look, highly visible older women are rewriting all the rules. From JK Rowling to Nicole Kidman; Michelle Obama to Anna Wintour, they are at the peak of their power and creativity.
They are engaged, influential and often increasingly political.
There’s even a new term to describe people with this no-age mindset: ‘perennials’
It was coined by US internet entrepreneur Gina Pell, 49, who explains, ‘Perennials are ever-blooming, relevant people of all ages who know what’s happening in the world, stay current with technology and have friends of all ages. We get involved, stay curious, mentor others, and are passionate, compassionate, creative, confident, collaborative, global-minded risk takers.’
Hell yeah! I want to be a perennial!
You can hear more about Gina Pell’s idea of perennials in this Youtube video. Not everything she says had the same point of resonance, but I like where she is coming from.
I think the Telegraph has misquoted her because Nina refutes the concept of being ever-blooming. My interpretation is that age should not be equivalent to relevancy.
A few weeks ago I posted a flippant comment on Facebook:
I doubt this is an original thought but: First World Problem 125: Why doesn’t the conditioner come in a bigger bottle compared to the matching shampoo?
One of my friends commented she runs out of shampoo first. I told her she was weird. That EVERYONE but her ran out of conditioner first. She thought I was weird. We bantered. Then the comments started coming thick and fast. I posted a poll asking our combined friends which they finished first, shampoo or conditioner?
The results were interesting with a 50:50 split. Being good scientists we understood we needed a bigger sample size, so I re-posted the poll to a bigger group (<30K members) and over the next weeks the poll received over 1000 votes and close to 50 comments.
It elicited some very interesting discussion… who’d of thought…
Frizz-less, blonde more but still all the same size!
In the end the results were close.
My friend’s hypothesis was supported and I had to agree she wasn’t weird.
It would seem the ratio of shampoo to conditioner use depends on a number of factors.
Hair length which seems quite obvious. The longer the hair the more conditioner is needed.
Curliness. One factor I didn’t know about is that a significant number of people (and we are talking mainly women here because they are the ones who responded) with curly hair do not use shampoo at all, only conditioner. There is in fact, a whole (secret to me) Curly Girl Method for looking after wavy/curly/coiled hair.
and an almost equal number of people
Who have short, thin or oilier hair who don’t use conditioner at all that balances out the no shampoo people.
Another new (to me) concept is the reverse shampoo method which uses conditioner first and then shampoo which is (apparently) good for fine hair.
All the same size! We need a social movement here!
So there you have it. It would seem that my original sample size of 100% of the people in my household who finish the conditioner first was not supported. I can see the need for a whole new social movement. Hair Buddies: Those who finish the shampoo first need to be introduced to those who finish the conditioner first so they can swap their excess product!
black coffee has no nutritional value. It has no fat, no carbohydrates, no protein, no vitamins and only minuscule traces of magnesium. We have to agree the only reason we drink it is because of the caffeine. BUT who drinks coffee black? Not many people! It’s all the stuff we add to coffee that boosts its nutritional status. The data in the table below is taken from Gloria Jean’s website and is fairly typical of the data available.
