There are a lot of other factors relevant to the discussion
@Freema - so many that they muddy the argument.
A well designed vegan diet is going to contain a LOT of fibre, and fibre has a big effect on slowing digestion and slowing glucose absorption.
A badly designed vegan diet is going to contain just as much rubbish and junk food as a non-vegan.
Processed food may be a factor.
The interaction of fat and carbs needs to be considered, not just one or the other.
Saturated fat is probably one small part of the equation.
Plus, from my point of view, I am not in the slightest bit interested as to why vegans have a higher or lower rate of T2 than non-vegans. It is a diet that my body
could not tolerate and my taste buds would reject. While I respect vegan ethics, they are not ethics with which I align.
Since I am ALREADY T2, and have found an excellent and effective way of controlling it (LCHF, with animal products) that suits my body, I am happy with that. In fact, I would rather have T2 than eat a vegan diet. Obviously that is a personal opinion, and other people feel very differently. I hope they are both happy and healthy.
