Whether you are sick with the flu or not, protein is always necessary to keep your body strong. Proteins are essential to help your body maintain and build strength. Lean meat, poultry, fish, legumes, dairy, eggs, and nuts and seeds are good sources of protein.

The FDA recommends that adults eat 50 grams of protein per day. Pregnant and nursing women need more. By eating foods high in protein, we also get the benefit of other healing nutrients such as vitamins B6 and B12, both of which contribute to a healthy immune system.
