PROTEINS

Proteins may either be

• Fibrous (structural) : insoluble and forming the structure of skin ,muscles ,tendons and hair.
• Globular : soluble protein including enzymes to promote biochemical reactions in the body.

The Recommended Dietary Allowance (RDA) for protein is a modest 0.8 grams of protein per kilogram of body weight. The RDA is the amount of a nutrient you need to meet your basic nutritional requirements. In a sense, it’s the minimum amount you need to keep from getting sick — not the specific amount you are supposed to eat every day.

For some people, there may be potential benefits of higher daily protein intake to preserve muscle mass and strength. How and when you consume protein might also influence its effectiveness. Some studies described in the summit reports suggest that protein is more effective if you space it out over the day’s meals and snacks, rather than loading up at dinner like many Americans do.
