There is lots there to interest a young athlete who wants to help get an edge on their performance. It is a book that stresses moderation and balance, has no magic formulas, and discourages the use of such hyped commodities as amino acid supplements. Unfortunately many athletes overdose on protein, thinking they need it for muscle building. What the excess protein does is cause an imbalance in their diet. Will most likely increase the fat level of your diet since most meat is also high in fat, this can lead to heart disease and has been implicated in the etiology of various cancers.
Excess protein is stored as fat.
Eating meat to the exclusion of other foods may lead to vitamin and mineral deficiencies and their resulting health problem e. g., little or no vitamin C from lack of fruits and vegetables can reduce immunity and lead to more colds, and other illnesses, too much protein can draw calcium out of the body, and coupled with a low calcium intake from lack of milk or other dairy and vegetable products, can cause suboptimal bone strength and perhaps lead to osteoporosis. It is important that you play up the good points of switching to a diet higher in carbos and fruits and vegetables, and down play the negatives of too much meat or protein. Secondly, I know of no 10 year old who has changed eating habits overnight. Make the changes gradually, allowing him to play a role in the rate at which it happens. You can also make the change easier by what you offer at mealtime, and the foods that you keep in the house.
