Protein diet advice: the choice of quality food

Protein diet, protein intake despite of the "quantity" requirement, but more important is "quality." In other words, the protein is not better, but the more excellent good.

The so-called high-quality protein, should have at least two conditions: first, contained in the full range of amino acids, especially the 8 essential amino acids the body can not be a lack; the second is contained in the amino acid-balanced, close to the body's physiological needs, the body's absorption and utilization rate.

This information, the lean meat, fish, poultry, eggs and other animal products are high-quality protein, on the contrary, plant food is more or less flawed. Methionine as the lack of soy protein, rice protein lacks lysine, isoleucine lack of peanut protein, are "incomplete protein", the absorption and utilization were lower than animal foods. Therefore, the best animal protein foods, should be classified as first choice.

Protein diet advice: eat a protein food at each meal

In the past that people should also eat a meal into several protein foods contain amino acids that could play a complementary role, to improve nutrition and weight-loss values, such as eggs, milk, beef + liver, ribs and so on tofu + was once considered the best combination.

However, this method was found inappropriate because of different proteins require different time and different digestive juices to digest, to effectively digest a meal of two or more different proteins is difficult. Because the protein is a more difficult to digest than other nutrients nutrients, so the meal is best to select a high quality protein foods, folk "do not eat tofu and meat" argument certainly has some scientific justification.

Protein diet advice: plant foods clever combination

Optimal animal protein, but requires a certain economic strength, long-term average family is difficult to enjoy. Workaround at this time is the ingenious combination of plant foods, the use of the complementary role of the protein, also can receive the desired effect.

Studies have shown that the nutritional value of two or more lower consumption of food by mixing, can complement each other to improve the structure and the proportion of amino acids, the "incomplete protein" into a "complete protein", beans and grains is Such a "best partner."

Alternatively, you can start from processing to improve the nutritional value of plant foods, the purpose is to remove much of the cellulose, and cellulose can impair the body's absorption of protein. Soybean, for example, if the whole food, containing 68% protein absorption rate, if processed into milk to drink, clear cellulose, the protein absorption rate can be increased to 90%.
