I have lived in the world for 60 years and during this time, doctors, nutritionists, etc., every now and then changed their minds (recent studies show) about healthy eating. This also applied to protein foods (eggs, various meats) , and fats (butter, lard, sunflower), fruits, etc. I adhere to this, listen to your body, eat a little and for pleasure, and all this "scientific data" is just making money and academic titles By the way, I feel good and happy with life.

Well, about all sorts, God forbid, "organic" products are sickening even to remember.
