what makes adventists her particular interest to scientists is that although about half a vegetarian around half eat meat so the two groups can be compared and unlike the wider population Adventist meat eaters tend not to be heavy smokers or drinkers factors which can influence any comparisons between vegetarians and more red-blooded Americans since the 1950s scientists at Loma Linda University have been conducting numerous Health Studies on Adventists the most recent have been trying to identify the health habits of the long livers I'm here to meet dr. Gary Fraser who's been leading this research for three decades covering over 150,000 Adventists these huge epidemiological studies crack people's diets and lifestyles and look for associations between what they eat their overall health and what eventually kills them like misery hello that's it I'm joining the good doctor for lunch and as I'm on a high meat diet my choices couldn't be more different so differences in their what we've got here then I've got pulled pork well dr. Fraser has a vegetarian salad with nuts a professor I had um bacon for breakfast as well okay I had four rashes big well I hope you survive this experiment help you so kind of broadly water of your studies revealed when you look at cardiovascular risk factors in a broad sense diabetes hypertension being overweight having increased blood lipid levels that the vegetarians are doing better than the non vegetarians and indeed that has translated in most of the studies to the vegetarians having a lower risk of heart attack and cardiovascular disease so that whole area I think is fairly well-established dr. Fraser found that men in the study who eat beef at least three times a week had double the risk of fatal heart disease compared to the vegetarians and this apparently massive risk to health was in people eating under sixty grams a day which is less than your average brick and half what I'm currently eating so you found that even you're eating what some people would go is quite a modest level of me just makes a difference I mean how big a difference you know I don't think we have all of the answers on that to be very precise about it and of course your your plate of food there's got some things on there that go beyond the meat that I wouldn't necessarily recommend so let me put it this way that plate as compared to this place where I'll for a place than meat with nuts and with whole-grain bread and so forth our evidences that you're probably looking at about a difference of five years four to five years in life expectancy you
