9 Foods That Should Be In Every Diet

TUNA

Fish on a budget! Tuna is a perfect food for those of us who want to bulk up our bodies without leaning out our wallets. One can of this budget delicacy contains approximately 41 grams of protein and just 5 grams of fat, all while only costing about $2.50 for a can. However, limit yourself to one can per week due to mercury content.
