Funny thing. I eat almost totally a raw diet, but for a completely different reason. After my husband died, I decided that there was no longer any reason to cook. It is time consuming and after I had done all the work, I ate in a few minutes. So why bother. There are so many other, important things to do with my time.
So now, unless something unusual happens, everything I eat is raw and fresh. I do not eat meat and have not for decades, so it is easy. Nothing else really needs cooking. I eat lots of nuts and seeds and whole grain cereals and breads and several servings of different fruits and veggies a day. Been doing this for years. No ill effects. I have lots of energy and rarely am ill. I am old and still function as I always have. I work hard and have a very high energy level. And my brain still functions properly too.
I think we all know what foods are good for us and what foods are not. What foods have the fewest negative implications for the world and for the individual. The problem arises because negative foods taste good. We tend to like only sweet and fat and salt. So we look for reasons to justify eating what is essentially junk food. Our taste buds are corrupted by years of bad eating. It takes some time to re-learn to appreciate the natural taste of healthy, positive foods.
I think people tend to say something is difficult or causes ill effects because they do not want to do it. I say, do it if you wish. For me, only positive results. If you do not wish to do so, then do not. No need to rationalize our choices. Just be aware of them and their consequences.
