Be careful of the “muscle” ambush! Sarcopenia is the prime culprit of elderly disability. After the age of 50, adults will lose 0.5-1% of their muscle mass each year. Muscle loss will not only cause inconvenience and reduce the quality of life, but it may also increase the risk of falls for the elderly, and even fractures, leading to disability and increasing the risk of death. At present, a new study found that intake of vitamin C from the diet may slow down muscle loss!
There are many reasons for sarcopenia, including endocrine disorders, muscle loss due to aging, lack of muscle activity due to inconvenience, insufficient protein intake, or free radicals generated in the body to destroy muscle cells, etc., all may cause sarcopenia , And the probability of occurrence is greater for men than for women.
The study found that people with more vitamin C in their plasma and diet have relatively higher skeletal muscle mass
In order to understand whether it is possible to supplement foods with antioxidant effects, such as vitamin C with strong antioxidant power, to fight free radicals and slow down muscle cell damage, according to a report from Science Daily, a report from the East of the United Kingdom Dr. Ailsa, Department of Epidemiology and Public Health, Norwich Medical School, Faculty of Medicine and Health Sciences, University of East Anglia (Department of Epidemiology and Public Health, Norwich Medical School, University of East Anglia) A Welch and Cambridge University (Cambridge University) collaborative research team conducted and published in the “Journal of Nutrition” (The Journal of Nutrition) research pointed out that the plasma and intake of the diet contains a higher concentration of vitamin C, its The appendicular skeletal muscle mass index (ASMI), which is used to assess body muscle mass, also seems to be high.
The experiment was conducted with more than 15,000 men and women aged 42-82 as subjects. The subjects’ health was checked during 1997-2000, and the subjects’ lean body weight was measured first. (Free fat mass, FFM), in order to understand the ratio of skeletal muscle to the body, the researchers successively calculated the total weight and BMI as parameters to obtain the value of skeletal muscle mass.
In order to further study whether there is a correlation between the content of vitamin C in the subjects’ plasma and the content of skeletal muscle, the researchers then collected the subjects’ blood when they were not fasting during the health check. The plasma is discharged, and metaphosphoric acid is used to stabilize the plasma state to minimize the chance of oxidation, and then stored at minus 70°C. After 1 week, the concentration of vitamin C in the plasma is measured by fluorescence measurement.
Vitamin C can help the formation of carnitine (carnitine) and collagen. Collagen is a key component of the structure of skeletal muscle and tendon. Carnitine plays an important role in the metabolism of long-chain fatty acids during physical activity.
As the European Food Safety Agency (EFSA) defines: the concentration of vitamin C in serum
There is a set of anti-sarcopenia for delaying the risk of old age!Research: Vitamin C helps slow down muscle loss
