HUMAN NUTRITION

Detailed explanation-1: -Carbohydrates are the main energy source of the human diet. The metabolic disposal of dietary carbohydrates is direct oxidation in various tissues, glycogen synthesis (in liver and muscles), and hepatic de novo lipogenesis.

Detailed explanation-2: -The healthiest sources of carbohydrates-unprocessed or minimally processed whole grains, vegetables, fruits and beans-promote good health by delivering vitamins, minerals, fiber, and a host of important phytonutrients.

Detailed explanation-3: -Sugars and starches provide glucose, the main energy source for the brain, central nervous system, and RBCs. Glucose also can be stored as glycogen (animal starch) in liver and muscle or, like all excess calories in the body, converted to body fat.
