Expert: the elderly, pregnant women and other people need to make up four groups of proteins

According to "China Preventive Medicine" released "1989-2009 China 9 provinces (regions) 18 to 45 years old dietary protein intake status and trends" Data show that dietary protein intakes above condition was significantly decreased from 65 to 73.3 grams per day dropped to 61.3 to 70.3 g. Professor Sun Mingxiao Beijing Hospital, director of nutrition, said the need to achieve a healthy nutritional balance, and protein deficiency is a common nutritional problem people.

孙明晓 said that the demand for proteins of different ages vary, especially in the growth stage, with age, the demand for protein will gradually increase. There are four categories of people at high risk of a lack of a protein, namely the elderly, pregnant women, surgery of the crowd and some diseases.

Elderly: digestive function decline, decreased absorption capacity, reduced interest on high protein food; vegetables, rice and other food-based low-protein diet; chronic diseases increase the body's nutrient consumption, hypoalbuminemia increased incidence of drug side effects the elderly and other problems are caused by lack of protein causes.

Pregnant women: pregnant women in the late and early lactation, the demand for protein is large, but according to the Chinese people's traditions and customs, will be a substantial intake of high-fat, high-cholesterol foods, high-quality protein in pregnancy and during the month intake, easily lead to nutritional intake is not balanced, it will increase the risk of pregnancy and a huge children's diseases.

Surgery patients: surgery entire process will accelerate the decomposition of protein, wound healing requires more high-quality protein, protein requirements increase dramatically in a short time the patient.

Some patients with diseases: liver disease and diabetes are at high risk of protein deficiency.

孙明晓 said, adding proteins, in addition to the amount needed enough quality. Where the definition of high-quality protein that contains all kinds of amino acids the human body needs essential amino acids required by the additional intake of supplements.

Sunming Xiao warned that in the disease state, growth and development period, special physiological periods and special age groups, should go to hospital for regular outpatient nutrition diagnosis, to determine whether the lack of human proteins, and to develop a nutritional supplement program based on the results.
