IS ALCOHOL GOOD FOR YOU? GINGER KOMBUCHA

June 22, 2018 3 Comments

It’s June and, in the UK, that means party-time. June has always been the month of weddings, big parties, Ascot, Wimbledon, Henley Royal Regatta and so on. This year – in my household – June has featured a celebratory bash every weekend, with several more during the week as my daughters celebrate the end of exams, birthdays etc. And then there’s the World Cup (every day). All this means flowing alcohol. Obvs.

But this year I’ve been keeping a beady eye on research into booze. Susan tackled the subject back in January, coming out in favour of a drink or two after the protective effects of alcohol were shown to outweigh its perils. We’ve long been enthusiastic followers of Blue Zones, those pockets inhabited by above-average numbers of the healthy and long-lived, who invariably enjoy a regular drink. And the association between moderate consumption of red wine and heart health has been demonstrated over and over.

Fast forward six months and new research suggests it may be time for a reassessment. Last week saw the publication of a new report linking alcohol to Alzheimer’s. According to researchers at the University of Illinois, alcohol could increase the risk of Alzheimer’s. The prevailing theory suggests Alzheimer’s is caused by the build-up of a protein – called amyloid plaque – in the brain, forming clots and clumps that prevent communication between neurons. Amyloid plaque is usually removed by microglial cells in a process called phagocytosis. This research, however, found that phagocytosis is 15% less effective after drinking. In other words, drinking alcohol makes it a little harder for your body to clear out the plaques thought to cause Alzheimer’s.

So should we be bothered? Only if we’re heavy drinkers or binge drinkers with a raised risk of Alzheimer’s, suggest the researchers. To boot, the research was carried out on rats (which we’re usually wary of) and involved what the researchers described as ‘heavy’ or ‘binge’ levels. Having said this, we recently interviewed an eminent Cambridge Professor of Neuroscience (more to come in our book) who believes this report is only the tip of the Alzheimer–Alcohol ice berg.

But what about cancer? While the association between light drinking and better cardiovascular health has been acknowledged, it’s (allegedly) a different story when it comes to cancer risk. As we wrote back in January, the World Health Organisation classifies alcohol as a Group One Carcinogen. Here’s what we wrote back then:

“It’s known there’s a link between alcohol and cancer – the latest report reveals more about why. Research published in the journal Nature found that consuming alcohol caused healthy stem cells to become faulty – and it’s damaged cells which can become cancerous. It seems that Acetaldehyde, the chemical produced when the body breaks down alcohol, can damage DNA within the blood stem cells. This permanently alters DNA sequences, making the cells more vulnerable to cancer.”

This sounded fairly conclusive to us (or as conclusive as anything can be in the world of medical research). So we took the view that if one has a family history of heart disease having a daily glass or two of red wine is probably a good thing. But that if one has a personal or family history of cancer, perhaps best to cut right back, or stop drinking altogether.

But another study, published yesterday, suggests that cutting back entirely may not be necessary. So good news for (moderately-drinking) June revellers.

A study from Queen’s University, Belfast, found that light drinking was associated with a reduced risk of overall mortality (ie death) and a reduced risk of cancer. Indeed, light drinkers (1-3 drinks a week) had a lower risk of cancer and dying than infrequent/non-drinkers (less than one drink a week) or heavy drinkers (2-3 drinks a day). NOTE: 2-3 daily drinks constitutes heavy drinking, while above 3 was classified as very heavy.

The study looked at over 99,500 American adults, across an average period of 8.9 years. The devil, as always, is in the detail. So let’s consider the ‘detail’:

A ‘drink’ was described as an American ‘cup’ of wine (beers and spirits were included, but I’ll focus on wine as that’s my tipple of choice). An American ‘cup’ is around 220 ml, so already that’s more than a standard UK glass (175 ml according to www.drinkaware.co.uk). Wine comes in a variety of strengths, muddying the waters still further. But let’s assume the people surveyed were drinking averagely alcoholic wine of 13%.

So a ‘light drinker’ (the person with the best possible protection according to this study) is someone drinking roughly between one and four 175ml glasses of wine per week. As the researchers concluded: ‘The results indicate that intakes below 1 drink per day were associated with the lowest risk of death.’ The report also found that the risk of some cancers increased with each additional drink per week, suggesting that going beyond 1-4 weekly drinks really isn’t sensible for anyone with a raised risk or family history of cancer.

Full report at http://journals.plos.org/plosmedicine/article?id=10.1371/journal.pmed.1002585

Meanwhile another recent study of over 13,000 adults – from Oxford University – found that alcohol in similarly small quantities also benefits cognition. Both non-drinkers and heavy drinkers had greater cognitive impairment than those drinking a few glasses of wine a week. In this case, the researchers concluded that up to 100 ml (that’s a very small glass or half a large glass) of wine a day could benefit the brain, but anything over that was potentially damaging: “Consuming more than one UK standard unit of alcohol per day is detrimental to cognitive performance and is more pronounced in older populations.” [1]

So, yup, that’s well below the UK guidelines of six 175ml glasses a week. The message is pretty clear, particularly for those of us in those crucial mid-life years: enjoy a 175 ml glass of wine 2-4 nights a week but no more. Equally, it’s good news for those worried that the odd glass might be harming them. It’s (probably) not.

Either way, we’ve been drinking less and less since we started our Age-Well Project. Indeed, we’re now both on a one-drink-a-day policy with a couple of mid-week alcohol-free days (ahem…mostly). But if we were being really prudent, we should probably cut back a bit more. But perhaps not in June. We’ll keep you posted.

In the meantime, I’ve been making my own ginger kombucha, and while I should point out that there’s very little medical research to back up any of the claims made for kombucha (although there’s some anecdotal evidence) research suggests its high probiotic content may be beneficial (as in the case of all fermented foods). This version is mildly sparkling, making it more like ginger beer – and a very acceptable alternative to a glass of wine! To get started, you’ll need to buy, beg or borrow a scoby (that’s the living yeasty-bacterial pancake that starts the fermentation process).

GINGER KOMBUCHA

Note: my recipe uses much less sugar than normal as I don’t like it sweet, but play around to find your preferred levels of sweetness. The longer you leave it to ferment, the less sweet (and the fizzier) it’ll become.
•9 ginger tea bags (I use Twinings Spiced Ginger)
•2 litres of boiled water
•100 g of sugar

Make a large bowl of ginger tea, add the sugar, stir to dissolve and leave to cool.

Remove the tea bags with a wooden spoon and pour the cool tea over the scoby. I use a plastic box with a lid, but you can use a bowl covered with a clean cloth and secured with a rubber band. Never mix the scoby with metal.

Leave the ginger tea + scoby for at least five days. Then strain with a plastic sieve, reserving the scoby for your next batch. Keep the tea in the fridge and serve it chilled in a wine or champagne glass as the perfect replacement for a glass of plonk.

I’m a novice at kombucha (there are entire websites and books devoted to the subject), so I’d love to hear any favourite recipes or top tips.

    Some of the very latest research https://www.thelancet.com/article/S0140-6736(18)31310-2/fulltext concludes the following “Alcohol use is a leading risk factor for disease burden worldwide, accounting for nearly 10% of global deaths among populations aged 15–49 years, and poses dire ramifications for future population health in the absence of policy action today. The widely held view of the health benefits of alcohol needs revising, particularly as improved methods and analyses continue to show how much alcohol use contributes to global death and disability. Our results show that the safest level of drinking is none. This level is in conflict with most health guidelines, which espouse health benefits associated with consuming up to two drinks per day. Alcohol use contributes to health loss from many causes and exacts its toll across the lifespan, particularly among men. Policies that focus on reducing population-level consumption will be most effective in reducing the health loss from alcohol use.”

    Of course there are many things that we do in life that come with risk and we make calculated decisions based on potential cost and benefit or enjoyment. Given the latest research however it seems prudent that the health guidelines be adjusted accordingly.

Everything we’ve learnt about ageing well points Everything we’ve learnt about ageing well points to a time (for women at least) in their mid-60s when the chronic conditions of ageing, like diabetes, heart disease and dementia, are - statistically - more likely to kick in. 

And we know that our reproductive hormones do so much more than prepare us to have periods and babies, we have receptors for them throughout our bodies and brains. 

Oestrogen, in particular, helps keep bones strong, blood vessels flexible, brains firing and inflammation levels low. Essentially, it wraps us up in a cosy protective cloak to keep us safe and healthy while we're able to reproduce, but once the eggs have run out - we're on our own! 

Between the average age of menopause at 51, and that time in our 60s when the chronic conditions of ageing are more likely to kick in, we have a decade or so in which it’s vital to focus on our health.

And how to do that? It’s on the blog - link in bio

If you’re lucky enough to have good metabolic he If you’re lucky enough to have good metabolic health you might want to thank your Mum today. Recent studies have found that women who move around during their reproductive years and during pregnancy and then breastfeed for a bit pass on a compound in their milk called 3SL which provides lifelong protection against poor metabolic health. The offspring of moving, breastfeeding Mums appear to have a lower lifetime risk of heart disease, type 2 diabetes and other chronic metabolic disease. Even gentle strolling during pregnancy and while nursing can produce this compound. So today we thank our Mums for that - as well as everything else.  Susan’s mum in the hat. Annabel’s mum in the pony tail.

There’s been lots of good news for walkers recen There’s been lots of good news for walkers recently. A study published last month found that over-60s who walked between 6000 and 9000 steps a day cut their risk of heart disease (including strokes and heart attacks) by 40-50 percent, when compared to a more typical 2000 steps a day. In fact this study found that for every additional 1000 steps walked, the risk fell still further.

A big hug from us to you to mark International Wom A big hug from us to you to mark International Women’s Day! 

The campaign this year reminds us to embrace equity as a way to recognise that each of us has different circumstances, and we need different resources and opportunities to reach an equal outcome. Of course, this is as vital in ageing and health outcomes as in every other field.  

So we’re embracing our age and hoping to grow older in a more equitable society ❤️
