Beware of the “muscle” ambush! Sarcopenia is the main culprit of elderly disability After the age of 50, adults lose 0.5-1% of their muscle mass each year. Loss of muscle will not only cause inconvenience and reduce quality of life, but can also increase the risk of falls for the elderly, and even fractures, leading to disability and increased risk of death. Currently, a new study found that vitamin C intake from the diet could slow muscle loss!
There are many reasons for sarcopenia, including endocrine disorders, loss of muscle due to age, lack of muscle activity due to inconvenience, inadequate protein intake, or free radicals produced in the body to destroy muscle cells, and the like. All can cause sarcopenia, And the likelihood of it happening is greater for men than for women.
The study found that people who have more vitamin C in their plasma and diet have relatively higher skeletal muscle mass
To understand if 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 by Science Daily, a report from Eastern United Kingdom Ailsa, Epidemiology Department 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) Research carried out by a team from Welch and Cambridge University (University of Cambridge), and published in The Journal of Nutrition, pointed out that the higher the concentration of vitamin C in the plasma and the dietary intake. The supplemental skeletal muscle mass index (ASMI), used to assess body muscle mass, also appears high.
The experiment was conducted with more than 15,000 men and women aged 42-82 as subjects. The health of the ‘subjects’ was checked during 1997-2000, and the subjects’ lean body weight was first measured. (Free fat mass, FFM), in order to understand the ratio of skeletal muscle to body, the researchers successively calculated total weight and BMI as parameters to obtain the value of skeletal muscle mass.
To further explore whether there is a correlation between vitamin C content in the ‘subjects’ plasma and skeletal muscle content, the researchers then collected the blood of the ‘subjects’ when they were not fasting during the health check. The plasma is emitted, and metaphosphoric acid is used to stabilize the plasma state to reduce the chance of oxidation, and then stored at minus 70 ° C. After 1 week, the concentration of vitamin C in the plasma is is measured by fluorescence measurement.
Vitamin C can help form carnitine (carnitine) and collagen. Collagen is a key part of skeletal muscle and tendon structure. Carnitine plays an important role in the metabolism of long-chain fatty acids during physical activity.
As the European Food Safety Agency (EFSA) defines it: the concentration of vitamin C in serum
A set of anti-sarcopenia for postponing the risk of old age! Research: Vitamin C helps slow muscle loss
