One vegan does not a movement make – less than 3,000 omnivores confirmed to have been “converted” by #Veganuary

Would a cheeseburger have tempted you away from #Veganuary?

Well, the official numbers have been published for #Veganuary, the 2018 attempt to entice people away from meat and towards the heady delights of almond juice and bean curd. The campaign has been cited as a magnificent success by such impartial publications as Plant Based News (has that been the guest publication on Have I Got News for You yet?) with 62% of survey respondents (who were not previously vegan) stating that they intend to continue with a vegan lifestyle.

On the face of it, that does sound impressive, admittedly slightly less so given that it means 38% of participants presumably thought “Sod that Veganuary lark, I’m off for a bacon sandwich with cheesy chips.”

Yet here’s the rub. Despite the claims of success, the survey was only sent to 50% of participants. That’s slightly odd given that, presumably, the majority signed up online with a valid email address. There was then a 14% response rate to the survey. That means that overall, only 7% of people^a who undertook Veganuary actually completed the survey.

Let’s assume that those who replied and confirmed that they were going to continue a vegan lifestyle were a random sample of the Veganuary population. This is a bit of a stretch, as anybody who’d not enjoyed Veganuary and was happily chomping down on a bacon sandwich would be considerably less motivated to reply than somebody who thought it was the best thing since sliced tofu. The stretch is underlined by the fact that 99% of respondents would recommend Veganuary to others – so basically a sub-section of happy campers. However, we’ll give it benefit of the doubt.

40% of people who completed the survey had previously identified themselves as omnivores (compared to 16% pescatarian, 33% vegetarian and 11% vegan). If we extend that statistic out to all the people who undertook Veganuary (168,500 people), then 67,400 people^b – just less than the population of Stafford in the West Midlands – were originally omnivores. So, if the assumptions made earlier hold true, 7% of those previously-known-as-omnivores replied to the survey (4,718 people^c) and of those, 62% aimed to stay vegan.

So 2,925^d omnivores have confirmed that they will remain vegan – are the rest enjoying a cheeseburger for lunch? Who knows. However, human nature being what it is, the “converted” number may be even smaller in a few months time.

Are vegan numbers increasing? Yes. Is it a massive trend? No. A fad prevalent in westernised society? Maybe. In 2016, 17.86 million babies were born in China. That’s 48,932 born per day, many of whom will choose to emulate the western diet. So, in just one day, 15.7-fold more babies are born in a country where meat and dairy consumption are predicted to increase over coming decades, than the number people who we know have actually pledged to stay vegan (having previously been omnivorous) after Veganuary. Was Veganuary a storm in a tea cup? Yes – with milk…and a cheese sandwich on the side.

^a 50% x 14%
^b 168,500 people x 40%
^c 67,400 people x 7%
^d 4,718 people x 62%

Cattle, Cowgirl Boots And Cancer

Posted on April 27, 2017 by bovidiva

581677_10153042743360587_388837289_n Last week I was lucky enough to chat with the fabulous Will Evans, a Welsh cattle and hen farmer on his Rock and Roll Farming podcast.

Unlike most of my media interviews, which are focus entirely on sustainability and have me spouting numbers like data is going out of fashion; this was a huge amount of fun and Will got me admitting to a celebrity crush, the fact that I have to put bacon and cheese on hot cross buns and the fact that, as an undergrad, I was so useless at presentations that even the lecturers felt sorry for me.

So if you fancy listening to a fabulous Welsh accent (Will) and a slightly overexcited Oxford/Shropshire/Montana-hybrid (me) discussing the best types of cheese, beating cancer at 25 and the perils of being a reformed vegan in addition to the best way to ensure future livestock sustainability (hint: there’s no one-size-fits-all), check it out here.

Bringing Home the Bacon – I’m a Cancer Survivor with Meat on the Menu.

Posted on October 26, 2015 by bovidiva

This week, the World Health Organisation (WHO) classified processed meat as being carcinogenic to humans and red meat as a probable carcinogen. Bacon has become the darling of the foodie world over the past couple of years, with bacon-flavoured popcorn, milkshakes and lollipops on the market, so does this new labelling mean that a package of bacon will be slapped with a warning sticker, and every hotdog will come with a side of medical advice?

Although the overall risk of developing colorectal cancer is small, headlines citing an 18% increase in colorectal cancer risk from consuming one 50 g serving of processed meat per day (approximately one hotdog) have led to consumer concern – including the (incorrect) assumption that eating 5 portions of processed meat would therefore lead to a 90% certainty of developing colorectal cancer.

Let’s examine the real risk. The average person’s risk of developing colorectal cancer is approximately 5%. If the WHO data suggesting an 18% increase in risk is correct, a daily 50 g serving of processed meat increases that risk to 5.9 % (an increase slightly less than 1 people per 100), of which between 0.65 – 5.4 people will survive for 5 years or more (depending on cancer stage at diagnosis). Despite the increase in meat consumption over the past century (and therefore assumed increase in processed meat consumption due to changes in dining habits and food availability), the death rate from colorectal cancer has dropped over the past 20 years. Moreover, in media articles discussing the WHO announcement, there is no mention of mitigating factors such as fruit and vegetable consumption. What happens if I eat 50 g of bacon within a huge salad with a side of oat bread, a meal high in dietary fibre, which is cited as having a protective effect against colorectal cancer? Or if I eat bacon after running five miles, given the role of exercise in preventing cancer? As with so many other health risks, it’s almost impossible to assess the impact of meat consumption in isolation.

Both alcohol and cigarettes are already listed as carcinogens by the WHO, yet how many people have actually forgone a glass of wine or pint of beer based upon the fear of cancer? By contrast, how many have cheerfully raised a glass to headlines stating that red wine may have beneficial health effects? Rather than health benefits, this announcement may reduce meat consumption by people who are most vulnerable to health complications from nutrient deficiencies (e.g. growing children, pregnant women and elderly people); not to mention the undoubted glee of anti-animal agriculture groups who will welcome the gift of further ammunition against meat consumption.

As a cancer survivor, I am the last person to downplay the importance of minimising cancer risk. However, ultimately we will all die and almost everything we do, from driving a car to choosing salad ingredients, carries some risk to health. Rather than the continuing mass of conflicting evidence, where every week a new article warns us about the latest cancer-causing drug/chemical/food; we need a balanced assessment of all cancer risks in order to make the best choices. I don’t smoke and I have had less than 10 alcoholic drinks in the past 2.5 years, but bacon remains on my dinner menu tonight.

Are We Producing More Food…and Feeding Fewer People?

Posted on July 18, 2013 by bovidiva

I’m ashamed to admit that the picture to the left is of the lunch table that a media colleague and I left last week – after spending an hour lamenting the fact that in the US, 40% of food is wasted (30% globally). Admittedly, that waste isn’t all down to restaurant portions (in our defense, we both had to fly home, so doggie bags weren’t an option) – however, according to FAO data here, consumer waste accounts for anything between 5% (in Subsaharan Africa) and 39% of total waste (North America and Oceania). The difference (anything from 61% – 95%) is made up from losses between production and retailing.

Losses from production to retail comprise by far the biggest contribution to waste in the developing world, which makes absolute sense – if food is your biggest household cost and hunger is a constant and real danger, the concept of wasting purchased food would seem ridiculous. In the developing world, a myriad of factors play into food insecurity including low agricultural yields, lack of producer education (particularly for women, who are often the main agricultural workers), political instability and military conflict (Pinstrup-Andersen 2000). However, possibly the biggest threat to food security is a lack of sanitary and transport infrastructure (Godfray et al. 2010) – building a milk pasteurization plant is a great opportunity to improve shelf-life, but can only be effective if producers have the facilities to refrigerate and transport milk. Improving tomato yields can reap economic dividends, but if they are transported to markets packed into plastic bags on the back of a bicycle, the wastage is huge. I’m not going to pretend I have the solutions to global food wastage, but what can we do in our own households?

Just as our grandparents learned during WWI and WWII – when food is scarce, you make the most of every single drop of milk or ounce of grain. Yet in the modern developed world, we can afford to waste almost 2/5 of our household food through not understanding expiration dates (cheese does not spontaneously combust into a listeria-ridden ooze at midnight on the day of the expiration date); throwing away the “useless” parts of food waste (radish leaves and wilted celery are actually really good in soup); or simply buying more than we need. In a recent study of greenhouse gases associated with US dairy production, the carbon footprint of a gallon of milk was increased by almost 20% simply because of the amount of “old” milk that consumers poured down the sink each day.

To go back to the picture above, it’s tempting to blame the restaurants – portion sizes tend to be huge, so in this carb-conscious world, it’s not “our fault” if we forgo the last 500 calories by leaving half a plateful of potato chips – they should have just served a smaller portion in the first place, right? Well, maybe. If we’re feeding dairy cows or beef cattle and seeing more than 5-10% feed unconsumed, we’ll reduce the amount fed. I’m sure that exactly the same practice would pay dividends in the restaurant world, and I’d be willing to bet that they could charge exactly the same price.

I spend most of my time myth-busting, showing that the modern beef and dairy industries are far more efficient than the farming systems of 40 or 70 years ago and that we now produce more food using far fewer resources. However, are we really feeding more people if we’re wasting 40% of our food? To suggest that we return to a practice from the WWII era feels almost heretical, but here’s an idea – rather than defining “sustainable” systems as those producing artisan cheeses from heirloom breeds cared for by hemp-wearing liberal arts graduates, why doesn’t every restaurant (or suburb) have a small herd of backyard pigs? Collect the waste food, boil it for 30 min to avoid disease issues, feed to pigs, produce bacon. What could be better? Admittedly, my mother country has banned this practice (I’m beginning to wonder if anything will be permissible in Europe soon), but let’s start the pigswill revolution! Doesn’t “You don’t have to eat that last potato, it’ll make some really good bacon and help us feed those 1 in 7 kids in our local area who don’t have enough food” sound more realistic than “Think of all the starving orphans who would enjoy your PB&J sandwich” (to which the continual smart-a** answer was “I’ll just mail to to them). Let’s do what the livestock industry does best – recycle waste resources to make safe, affordable, nutritous meat!
