Increasing plant protein intake can improve muscle health in Chinese elderly population

 Although overall protein intake recommendations are insufficient to counteract muscle loss, protein intake from plant-based sources may help improve muscle health in China's elderly population, researchers say.

Since most of the existing data on the relationship between dietary protein intake and muscle mass come from Western countries, researchers in China conducted a cross-sectional study to investigate how different amounts and sources of protein intake affect aging Chinese Human muscle mass. The article titled "Association of Dietary Protein Intake with Muscle Mass in Elderly Chinese: A Cross-Sectional Study" was published in Nutrients recently.

The study analyzed data based on the 2018 China Health and Nutrition Survey (CHNS), which included 4,826 participants aged 60 and over from 15 provinces.

Protein intake data were assessed using three days (two weekdays and one weekend) of 24-h dietary recall obtained through face-to-face interviews with participants.

Their limb skeletal muscle mass (the sum of muscle mass in all limbs) was assessed by bioelectrical impedance analysis, a method of measuring body composition based on the rate at which electrical current passes through the body.

Using soy protein isolate to make tofu

图片
Soy protein isolate is a plant-based protein extracted from soybeans that has high purity, high nutritional value, and no cholesterol. ‌ It is a protein powder obtained from low-temperature desolubilized soybean meal as raw material and processed through a series of processes. Its protein content is more than 90%, it is rich in amino acid types, and contains essential amino acids for the human body. Soy protein isolate is not only nutritionally comparable to animal protein, but because it does not contain cholesterol, it is one of the few plant proteins that can replace animal protein. ‌ Soy protein isolate has a wide range of applications and can be used as a food additive to make baby food, sports drinks, instant products, etc. It also has various health benefits such as boosting immunity, promoting wound healing, lowering cholesterol, preventing osteoporosis, etc. In addition, soy protein isolate also has a unique role in food processing. For example, injectable soy protein isolate ...

Protein is the main participant in life activities and plays an important role in the human body. Normal adults should consume a certain amount of protein every day to maintain a positive nitrogen balance in the body. Special groups should pay more attention to protein intake to maintain health. In fact, protein also has pros and cons. There are some small details that are worth noting when choosing protein-rich foods. Today, let ’ s talk about them . ■ Soy protein The protein content of soybeans is between 36% and 40%, and the protein content of soybeans per 100 grams is about 35.0 grams. Its amino acid composition is also relatively reasonable, and its utilization rate in the body is high. It is a very good source of protein among plant proteins. Dried tofu, tofu brain, and soy milk are all good choices for sources of soy protein. Now the Isolated Soy Protein(90% protein) and Soy Protein Concentrate(65% protein) are also the better options. ■Egg protein Eggs contain 11%-14% protein a...

A good helper for regulating blood lipids - soybeans

图片
Soy milk, tofu, dried tofu, tofu skin...a soybean can be eaten in a variety of ways. It ’ s also a “ bean ” , why are soybeans so favored by people?   Bad living and eating habits have caused many people to have high blood lipids. If you want to improve blood lipids, adjusting your diet is the basis, and soybeans contain seven experts that protect blood vessels and regulate blood lipids. 1. Soy protein. Replacing some animal protein with soy protein can help reduce LDL cholesterol ("bad" cholesterol), thereby reducing the risk of atherosclerosis and cardiovascular disease. 2. Soy isoflavones. Soy isoflavones have certain antioxidant effects, which are helpful in scavenging free radicals in the human body, preventing lipid peroxidation, and preventing cardiovascular diseases. 3. Soy lecithin. Soy lecithin helps improve fat absorption and utilization, prevent cholesterol deposition in blood vessels, reduce blood viscosity, promote blood circulation, and prevent cardiovascular d...
