Diet is the most important aspect to healthy people.
The saying “you are what you eat” has much deeper meaning.
Just look at the obesity levels in US. The millions of people with heart disease and type 2 diabetes.
Looks at pictures of people from 1930s depression era, when lots of people were broke and down on their luck. The people look better and healthier, even with eating the meager food they ate with depression era economy.
The food back then were truly organic and natural, real meats and fats. What we call food now are processed blocks of chemical concoctions with added sugar.
