Thanks, Doloroes, I truly appreciate your good intentions. And I absolutely believe that vegetarian diets can be very beneficial for some, or even many people. My issue is not with the taste (except for Tofu which I absolutely hate). My issue, and it is an entirely personal one, is with the fact that I really can't be without meat. I do have the physical reactions to meat deprivation, which even eggs can't rescue.

We are beginning to understand that dietary preferences (vegetarian vs. "carnivore") may be determined by genetics, too. A recent Mendelian randomization study using data from the UK Biobank uncovered that vegetarians and vegans have a set of gene polymorphisms that correlate with fat digestion ability. We are in the very early stages of uncovering those links, which is why I haven't written an article about this yet, But I have it on my radar. The genetic link makes sense when you consider that Indians, who have one of the highest prevalences of vegetarian/vegan diets probably share a genetic variety.

So, thank you very much for your kind invitation, which is a bit difficult for me to accept for geographical reasons. I'd venture any type of food, but I'm reasonably sure, that I won't switch to vegetarian. After all, my meat-leaning diet has served me very well for the past 6 decades. But, as I said, from the bottom of my heart, thank you very much for your kind concern.
