How Much Protein?

Ever wonder how much protein is in the food you eat? Here's a rundown on some of the foodstuff:

Hamburger patty, 4 oz – 28 grams
Chicken breast, 3.5 oz - 30 grams
Fish fillets or steaks (cooked) , 3.5 oz. - 22 grams
Tuna, 6 oz can - 40 grams
Bacon, 1 slice – 3 grams
Ham, 3 oz serving – 19 grams
Egg, large - 6 grams
Milk, 1 cup - 8 grams
Tofu, ½ cup - 20 grams protein
Peanut butter, 2 Tablespoons - 8 grams

Whey Protein

Whey protein is the name for a collection of globular proteins that can be isolated from whey, a by-product of cheese manufactured from cow's milk. It is typically a mixture of beta-lactoglobulin (~65%), alpha-lactalbumin (~25%), and serum albumin (~8%), which are soluble in their native forms, independent of pH. Whey has the highest Biological Value (BV) of any known protein.

Whey protein typically comes in three major forms: concentrate, isolate and hydrolysate. Whey protein concentrates contain a low level of fat and cholesterol but generally have higher levels of bioactive compounds, and carbohydrates in the form of lactose — they are 29%-89% protein by weight. Isolates are processed to remove the fat, and lactose, but are usually lower in bioactive compounds as well — they are 90%+ protein by weight. Both of these types are mild to slightly milky in taste. Hydrolysates are predigested, partially hydrolyzed whey proteins which consequently are more easily absorbed, but their cost is generally higher.

Protein Vs. Obesity

Swedish scientists have discovered a protein that stimulates the formation of fat cells, a development that could potentially lead to treatment for obesity. The protein, according to Karolinska Institute, is called TRAP (tartrate-resistant acid phosphatase), and "stimulates the formation of new fat cells and can thus precipitate the development of obesity."

Proteins & Hunger

High protein diets may be the best way to keep hunger in check, according to the results of a study done by US researchers.

According to the study done by University of Washington, among the nutrients, proteins are best suppressing ghrelin, a hormone secreted by the stomach that stimulates appetite.

Eat Your Oats

Oat is the only cereal that contains a globulin or legume-like protein, avenalin, which is also a major (80%) storage protein.

Oat protein is nearly equivalent in quality to soy protein, which has been shown by the World Health Organization to be the equal to meat, milk, and egg protein. The protein content of the hull-less oat kernel (groat) ranges from 12–24%, the highest among cereals.

Furthermore, oat bran, the outer casing of the oat contains beta-glucans. Its consumption is believed to lower LDL ("bad") cholesterol, and possibly to reduce the risk of heart disease.

Whey protein powder is commonly used by bodybuilders and other athletes to accelerate muscle development and aid in recovery.

Got Milk?

Milk is a very good source of vitamins and minerals. A serving (1 cup or 250 ml) of 2%-fat milk contains 285 mg of calcium, and 8 grams of protein, and a number of other nutrients, including Vitamins A, D, K, B12, riboflavin, biotin, potassium, magnesium, thiamine and selenium.
