Nearly 1/3 Of Early Deaths Could Be Prevented By Giving Up Meat, Says Harvard
Whether it be from a place of compassion, growing concern for environmental sustainability or a more thorough understanding of what it really means to be healthy, one thing is clear — more and more people are cutting out or at least cutting back on meat and other animal products, and for good reason. Scientists from the University of Harvard have found that at least one-third of all early deaths could be prevented if everyone moved over to a vegetarian diet.
Dr. Walter Willett, professor of epidemiology and nutrition at Harvard Medical School says that the overwhelming evidence in regards to the benefits of a plant-based diet has been extremely underrated.
Figures from the Office for National Statistics suggest that around 24 percent or, 141,000 deaths each year in Britain were entirely preventable, the majority of those numbers were due to smoking, alcohol or obesity.
New figures from Harvard are now suggesting that at a minimum, 200,000 lives could be spared each year if people were to simply cut meat from their diets.
While speaking at the Unite to Cure Fourth International Vatican Conference in Vatican City, Dr. Willet said, “We have just been doing some calculations looking at the question of how much could we reduce mortality shifting towards a healthy, more plant-based diet, not necessarily totally vegan, and our estimates are about one-third of deaths could be prevented.
“That’s not even talking about physical activity or not smoking, and that’s all deaths, not just cancer deaths. That’s probably an underestimate as well as that doesn’t take into account the fact that obesity is important and we control for obesity.
“When we start to look at it we see that healthy diet is related to a lower risk of almost everything that we look at. Perhaps not too surprising because everything in the body is connected by the same underlying processes.”
Another speaker at the conference, British-born Professor, David Jenkins of the University of Toronto, credited with developing the glycemic index, which outlines how carbohydrates impact blood sugar, also told the conference that the benefits of a plant-based diet have been ‘undersold.’
According to Jenkins, humans would do better by following a “simiam” diet, similar to that of lowland gorillas who eat stems, leaves, vines, and fruits compared to the increasingly popular “paleo” diet, which cuts out carbohydrates and encourages regular consumption of meat.
Where’s The Science?
Dr. Jenkins and his team recently teamed up with The Bronx Zoo in New York and traveled to central Africa to research and record the feeding habits of gorillas.
After recreating the diet for humans, translating to 63 servings of fruit and vegetables a day, they observed a 35 percent fall in cholesterol in only two weeks, which is the equivalent of taking statins.
“That was quite dramatic,” he said, “We showed that there was no real difference between what we got with the diet and what we got with a statin.”
Statins are a prescription drug that is often prescribed by doctors to patients with high cholesterol in an attempt to stave off heart disease. Nearly 15.5 million people are currently eligible for statins equating most men over 60 and most women over 65. Because of side effects, many prefer not to or stop taking the drugs — what if the answer was much more simple the whole time?
According to Dr. Jenkins, “We’re saying you’ve got a choice, you can change your diet to therapeutically meaningful change or you can take a statin. Drug or diet.”
President of the Committee for Responsible Medicine has also stated that people need to wake up to the health benefits of a plant-based diet.
“I think we’re underestimating the effect,” he told delegates. “I think people imagine that a healthy diet has only a modest effect and a vegetarian diet might help you lose a little bit of weight. But when these diets are properly constructed I think they are enormously powerful.
“A low-fat vegan diet is better than any other diet I have ever seen for improving diabetes. With regards to inflammatory diseases like rheumatoid arthritis, we are seeing tremendous potential there too. Partly because of things we are avoiding and cholesterol but also because of the magical things that are in vegetables and fruits which just aren’t in spam.”
