BEST SOURCE OF PROTEIN

BEST SOURCE OF PROTEIN IS FISH AS YOU DO NOT GET AS MUCH SATURATED FAT WITH IT.
From my point of you, and I am not a dietitian, is that the best diet, or style of eating is very simple: fish or any other seafood, vegetables and fruits.
This way of eating will normalize your weight, help your heart, arteries, will kill your headache,  fill you up with energy and happiness.
It will help you to fight cancer, protect from colon cancer as it normalize your digestive system
