Fundamentals of Nutrition with Protein

Nutrition and Protein, what you need to know?

Things you must know while getting your supplement or looking out for more nutrition. i found this article in my email, so i decided to share here. Enjoy below: 

 

"Before we can determine which supplements we need to take, we need to take a quick look at the fundamentals of nutrition—that is, proteins, fats, and carbohydrates as nutrients. For many people, this is where their nutritional knowledge begins and ends. They count calories and compare ratios of fat calories to total calories. In most hospitals, the sole concern of the certified nutritionists who prepare hospital food is putting together a proper balance of proteins, fats, and carbohydrates. As you will soon learn, this is tantamount to nutritional insanity.
Proteins are essential for the growth and repair of all body tissues. They are made of amino acids, some of which your body can produce by itself, and some of which must be included in your diet. A great deal is made about the need for protein, but the fact is our protein requirements are not really very large and are easy to fill. The official Reference Daily Intake (RDI) for protein is approximately 50 grams (g) per day, but if you're at all active you probably need more. To figure out your protein requirement, it works out to 0.33–0.50 grams per pound of your 'ideal' body weight (or about 0.75–1.0 gram per kilo), depending on activity. Keep in mind that 50 g is only about 1.8 oz. A performance athlete might need to double that, but that's still only 3.6 ounces a day.
Theoretically, milk is a top-rated protein, but in reality it's not. As we've already discussed, it messes up the pH (acid/alkaline balance), which results in incomplete digestion. It also has large proteins, such as casein, alpha-lactalbumin, and beta-lactaglobulin, which are difficult to digest and can cause allergic reactions. Meat and fish are fine, but surprisingly not that efficient—they provide only about 20–25 percent protein. You need about 10–12 ounces of meat to get 2.5 ounces of protein. That's about four times the maximum healthy level of 3 ounces per day of meat. Eggs are the most efficient, bioavailable source of protein around, but are also extremely allergenic. Surprisingly, some of the best sources of protein are vegetarian. Spirulina and chlorella are both high in actual percentage of protein (60–80 percent compared to meats) and are also in a more bioavailable form. Rice protein and yellow pea protein are also great sources, particularly in combination, and they're hypoallergenic. Hemp protein is a good balanced food, but generally contains less protein than rice and pea proteins."
