Once Lara Flanagan made the switch to a meat-free diet, there was no going back. “Now I would not live any other way,” says the 46-year-old freelance consultant.
“I think it is the healthiest way to live, the best for our planet and also it is wonderful to know you are living a cruelty free life.”
For some of us, however, the switch to meat-free eating is far from appealing.
Indeed, Journalist Doug Larson was quoted saying: “Life expectancy would grow by leaps and bounds if green vegetables smelled as good as bacon.”
But even the most carnivorous ears will prick up at recent claims that tens of millions of deaths could be prevented annually, simply by turning to a plant-based diet.
“That's not even talking about physical activity or not smoking, and that's all deaths, not just cancer deaths,” said Walter Willett, one of the Harvard Medical school researchers behind the claims.
Speaking at the Unite to Cure Fourth International Vatican Conference, Dr Willett said, “how much could we reduce mortality [by] shifting toward a more plant-based diet? Our estimates are about one third of deaths could be prevented.”
Globally, roughly 30 million deaths every year are categorised as ‘preventable’ – those caused by factors we could arguably do something about, such as smoking, poor diet and obesity, for example, suggests research published in The Lancet in 2018.
Needless to say, shaving that stat by a third would be a serious achievement – 10 million lives saved, in fact.
Why is vegetarian so superior?
It’s not news that vegetarian diets, when managed well, lead to reduced body mass index, blood pressure and heart attack risk, or that red meat can increase the risk of cancer.
But the benefits of trading our steaks for veggies appear to have been vastly underestimated, if the bold new Harvard Medical School claims are to be believed.
The figures, much higher than previous estimates, are yet to be published in a peer-reviewed journal so should be interpreted with caution, however, thus far, they’ve received support within the scientific community.
Dr Neal Barnard, President of the Physicians Committee for Responsible Medicine, for example, told the Unite to Cure conference that “I think we’re underestimating the effect”.
“When these diets are properly constructed I think they are enormously powerful.”
Diabetes and rheumatoid arthritis are among the conditions that benefit from vegetarianism and veganism, he added. This is “partly because of things we are avoiding, like cholesterol and saturated fats, but also because of the magical things that are in vegetables and fruits which just aren’t in spam”.
Kicking meat to the curb (at least part-time)
Consuming a “properly constructed” vegetarian diet takes effort – you’ve got to ensure vitamin B12, iron and other key nutrients, found mainly in animal products, remain in ample supply. (This means upping the amounts of leafy greens, legumes, reduced-fat dairy products and eggs in your diet).
But you needn’t go the whole-hog for your health, and the environment to reap the benefits.
Limiting red meat consumption to a maximum of three times per week, for example, has the potential to prevent 31,000 deaths from heart disease, 9000 deaths from cancer and 5000 deaths from stroke, based on a 2010 Oxford University study.
Starting off can be as simple as adopting concepts such as ‘Meat-free Monday’ – choosing one day a week to forgo the meat in favour of much-needed veg.
