How much does he eat? There is an inverse relationship between caloric intake and mortality; the less you eat, the longer you live. Also, keep in mind that animal protein is not necessarily meat, meat would be a subset of animal protein, which means this study does not remotely conclude that meat intake is inversely proportional to mortality.

Though some will claim otherwise and I envy them, it is not easy to eat vegetarian, so your anecdotal insinuation that vegetarianism is less healthy could be due to the fact that readily available options, if they exist, are vanishingly slim. For one, there seems to be meat or meat byproduct in everything. No major restaurant chain caters to vegetarian diets, unless you count Subway with all the exposed deli meat and preps touching meat, it can kill appetites, and I wouldn't call Taco Bell's bean burrito catering to the vegetarian diet. Vegetarian restaurants are incredibly rare, and I don't understand why. Most restaurants will have a single dish that is vegetarian on a menu that is 4-5 oversized pages long. And if you're in the sticks, forget it everything has meat, and often it is causing trouble to ask the meat be left out.

And when you do find a vegetarian restaurant, the entrees are often exotic and bizarre (even if delicious, they just don't need to be that complicated or expensive). I don't get why there isn't a restaurant that prepares and serves everything Americana except the gratuitously included meat in every single entree. If I had any startup money, I'd open a chain of vegetarian fast food restaurants that serves all vegetarian entrees, with plenty of calories and nailing all the nutrition metrics, but made only with familiar food resulting in familiar, non-intimidating dishes with prices compatible with those of any fast food place.
