My late partner's son is a doctor and he admitted (and studies have shown) he got little training in nutrition. To many medical students/doctors food is just food.
One thing I did notice was the picture of rice. White is not a good source of nutrition as most has been scraped off. Brown is much better. However, it can go rancid and needs refrigeration and it takes longer to cook.
Thanks. I'd heard of complete protein dishes such as Rice & Beans and I long ago heard about not requiring animal amino acids but I didn't know that (from the link) any single whole natural plant food, or any combination of them, if eaten as one’s sole source of calories for a day, would provide all of the essential amino acids and not just the minimum requirements but far more than the recommended requirements.
I suspect that my particular vegetarian diet will not be impacted much by this idea but I'll definitely have to study up on it. Lol. Thanks again.
