And, finally, I`m no close-minded anti-vegetarian Trump-esque freak.   

At one point in my younger years, I tried to be a lacto-ovo vegetarian for about 18 months.  It failed notwithstanding working really hard to incorporate a range of different types of vegetarian protein and working hard to get the right fats etc.   On the good side, I learned to prepare vegetables in a range of interesting and appetizing ways.   Increasing veggie variety is never a bad thing.

It was actually a naturopathic doctor who told me I needed to be back on meat protein pronto -- and, he was right.   I started feeling better the day after having a yummy lamb stew at a Middle Eastern restaurant, and never looked back.

There are some people whose genetic make-up allows them to function well on a vegetarian diet, but many do not.   Misguided food fortification is part of the problem, where synthetic `vitamins` are added to foods that mess up about half of the general population`s health.
