Is this a new study? From what I last heard the number of vegans in the
Oxford study were too few to be conclusive, even adding up all the study
data available, there were still too few vegans. Furthermore typical vegan
diets reduce total cholesterol to around the 150 to 160 level which is not
particularly low.

Maintaining sufficient B12 status is potentially beneficial irrespective of
type of diet eaten. Meat eaters can take B12 supplements and probably
benefit as well. For example, the B12 in meat is often poorly absorbed by
the elderly, yet they are in a high risk group.

The news is still good for veg*n diets, they reduce risk vs the standard
omnivore diet, but the data so far doesn't support a need to remove animal
products totally from the diet for the best longevity.
