The highest-quality proteins come from animal sources—eggs,
fish, poultry, meat and dairy products. Much lower in value (be-
cause they are not as readily assimilated) are proteins of plant
origin—beans, rice, corn, peas and nuts. To make these more
readily available for use in the body they should be taken with
animal proteins. Generally speaking, the bodybuilder will expe-
rience the fastest growth by choosing protein from animal
sources.
Carbohydrates raise the blood sugar level and supply the
muscles with energy. You need a certain amount of carbohy-
drates to fuel your system so it can utilize its available protein to
the greatest advantage.
Fats too are essential to a good diet. Not only do they heat
your body and lubricate your body parts, they also provide a
necessary base for carrying vitamins A, D and E.
Aside from protein, carbohydrates and fats, you should have
adequate vitamins and minerals. It is preferable to get your vita-
mins and minerals from the foods you eat. However, in acceler-
ated training situations it is advisable to reinforce your regular
diet with supplements. The following are the vitamins your body
needs to maintain itself properly:
Vitamin A—important to good vision, skin texture, and main-
taining the delicate linings of the nose and throat. Sources: eggs,
liver, milk, carrots, spinach.
Vitamin B complex (twelve B vitamins, including niacin, ri-
boflavin and thiamine)—essential to a good balance of the ner-
vous system and the normal functioning of the digestive system.
Sources: eggs, whole grains, poultry, green vegetables, fish, fruit,
milk, brewer's yeast.
Vitamin C—promotes healing; builds up resistance to infec-
tion; aids in the production of connective tissues; generally
strengthens the skeletal and vascular systems. Sources: citrus
fruits, tomatoes, green vegetables.
Vitamin D—essential for strong teeth and bones. Sources:
milk, fish, egg yolks, chicken livers and, especially, direct
sunlight.
Vitamin E—contributes to the functioning of the circulatory,
respiratory and reproductive systems. Sources: wheat germ, veg-
etable oils, eggs and leafy green vegetables.
