of energy.
2. Sugars, starches, and cellulose provide 4 cal/g.
3. Carbohydrates promote normal fat metabolism,
spare protein, and enhance lower gastrointestinal
function.
4. Major food sources of carbohydrates include

fats,
and carbohydrates and act as catalysts for metabolic
functions.
2. Vitamins promote life and growth processes,
and maintain and regulate body functions.
3. Fat-soluble vitamins A, D, E, and K can be stored
