CHO’s Fiber Not digested by humans Aids normal elimination ? Risk of colon cancer

Energy Sources Fats Saturated versus unsaturated Concentrated source of energy Ideally <30% Saturated versus unsaturated Animal and Plant sources Cholesterol (<300 mg/day) Fat substitutes

Energy Sources Proteins **growth, maintenance & repair Amino acids 10 - 15% of intake Amino acids Need & consumption levels

Basic Nutritional Needs Are the nutritional needs for athletes different? Pre-event meal vs regular nutritional habits?
