hair_loss_types : Types of hair loss and their causes

• Androgenetic Alopecia: This is by far the leading type of hair loss in men and women and is a result of genetics. This genetic hair loss is hereditary and can be inherited from either side of the family. Commonly known as male and female pattern baldness, this type of hair loss is due to the action of a chemical known as dihydrotestosterone (DHT) which attacks the hair follicles and causes hair loss.

Whey protein is not something new and has been available for hundreds of years to individuals who valued the role of a nutritious diet in achieving optimal health. During the last 15-20 years the value of whey protein has become more widely known, especially in the area of sports nutrition. More recently, whey protein has been singled out as a super-star ingredient for other types of products including ones formulated for weight loss, infant nutrition and immune support.

Whey protein is a high quality protein powder from cow's milk. Milk has two proteins: Casein (approximately 80%) and Whey Protein (approximately 20%). Whey protein is more soluble than casein and also has a higher quality rating. It is often referred to as the "Gold Standard" of protein as it is the most nutritious protein available.

There may be a large difference between whey protein concentrate and isolate. Whey protein isolate is the most pure and concentrated form of whey protein available. It contains 90% or more protein and very little (if any) fat and lactose. Whey protein concentrate has anywhere between 29% and 89% protein depending upon the product. As the protein level in whey protein concentrate decreases the amounts of fat and/or lactose usually increase.

• Repair body cells
• Build and repair muscles and bones
• Provide a source of energy
• Control many of the important processes in the body related to metabolism

The body is able to make non-essential amino acids from other amino acids in the body. However, the body is not able to make essential amino acids and the only way to get them is by eating high quality protein foods. Protein sources that contain all of the essential amino acids are called complete proteins. Whey protein is a naturally complete protein.

Protein needs vary by person depending upon age, weight, sex, activity level and overall health. Athletes and individuals with special medical needs often need more protein than the recommended dietary allowance, or RDA.

Adding whey protein to the diet is a great way to jump-start a weight loss program. Whey protein is a key ingredient in numerous weight loss and meal replacement products and whey protein isolate (with no fat or carbohydrates) is often the preferred choice. Studies have found that individuals who combine diets with leucine rich protein foods, like whey protein, and exercise have more lean muscle tissue and they lose more body fat. As they lose fat their metabolic rate increases and they naturally burn more calories each day. Another way that whey protein helps manage weight is by promoting satiety, or a feeling of fullness. One recent study showed that whey protein was superior to casein, the other protein in cow's milk, in promoting satiety.

Milk is a highly nutritious beverage however, it only contains about 1% of whey protein. In order to get all the benefits of whey protein, you need to take a concentrated whey protein powder like whey protein isolate.

Whey protein is a soluble, very easy to digest protein. It quickly enters the body to provide the important essential amino acids needed to nourish muscles and other body tissues. This is one of the reasons it is a common ingredient in infant formula and protein supplements for medical use.
