9. Red Meat
Perhaps a surprise member on the list, red meat has been an indispensable part of the human diet for millions of years. While some studies suggest meat has some carcinogen-like properties, properly raised beef and pork is perfectly healthy provided you follow some healthy lifestyle patterns like exercising. Red Meat, more than poultry or fish, contains a full profile of essential and non-essential amino acids, as well as being far more satiating than almost any other commonly eaten food item.
