Unsaturated/Good (Avocado,Olive&fish oil)

Functiom of fat

Provides energy & help body absorb materials and minerals. Gives insulation and protects organs.

Protein functions

Build and repair muscle tissue, make enzymes and hormones.

Protein sources

Meat,Poultry,Fish,Eggs,Dairy,Legumes,Nuts.

Importance of protein in sports
