Most cells in the human body need vitamin D. The nutrient also has an important role in preventing symptoms and diseases that may occur after menopause – including osteoporosis, muscle weakness, dry mucosa, mood swings, cardiovascular disease, type 2 diabetes, and cancer. In an article that is published in Frontiers in Physiology, the authors address the widespread vitamin D deficiency that is an overlooked problem in post-menopausal women, and they suggest striving to have optimal vitamin D levels in the blood throughout life.
- and older people should ideally consume more than the official recommendations
Undernourishment and lack of protein is common among older people. Evidence even suggests that the recommended daily intake of protein is too low, at least as far as seniors is concerned. The problem is most likely a slowdown of the muscle-building enzyme processes. The quality of protein also has something to say just like the amount of physical activity is a factor.
CLA (conjugated linoleic acid) is a group of omega-6 fatty acids, of which there are 28 different varieties. A few of them are associated with health benefits. This is the case with the following two types, Trans-10,Cis-12 and Cis-9,Trans-11
Ageing processes are associated with loss of muscle mass and impaired physical performance, both of which tend to lower quality of life. It is commonly known that coenzyme Q10 plays a significant role in cellular energy turnover and protects against oxidative stress. Now, two independent cohort studies even show a relation between the body’s Q10 status and muscle strength. Earlier research even suggests that Q10 supplements may help older people develop more youthful muscle fibers. Individuals who take cholesterol-lowering statins are advised to take Q10 supplements.
For the first time ever scientists from California have discovered copper's role in the burning of fat. This improves the nutrient's reputation as an essential nutrient.
Loss of muscle mass may be a result of a number of factors such as lack of exercise, too little protein, and ageing. Insulin resistance and acid accumulation are also related to loss of muscle mass, and it looks as if increased intake of vegetables with potassium, a base-forming mineral, is linked to decreased loss of muscle mass in men – but not in women.
Q10 is involved in the energy turnover in all cells. The highest concentration of the compound is found in the heart, as this muscle needs to pump day and night and to supply muscle cells with more blood when we are physically active. The cellular energy turnover takes place inside some minute powerhouses called mitochondria. A Danish-Swedish study has shown that the mitochondria in the muscle cells of top-notch athletes have a different construction that makes them able to produce up to 25 per cent more energy. Earlier studies show that Q10 is able to improve athletic performance, and it all boils down to optimizing the energy turnover in the cells.
Girls with high blood levels of vitamin D are generally stronger, while the same relation is not seen in boys, according to a cohort study from Odense University Hospital in Denmark. The study is published in the Journal of Clinical Endocrinology and Metabolism. Nonetheless, all humans need adequate levels of vitamin D, as the nutrient has a number of other important functions in the body.
Preventing and treating sarcopenia and physical decline requires enough protein and essential nutrients
Most people thrive on the idea of staying physically active throughout life, but as we grow older, our skeletal muscle slowly vanishes and our figure changes. This is known as sarcopenia and is one of the main reasons why older people become more fragile and perhaps even disabled. Exercise and diet play a major role, and it seems that the official dietary guidelines are not optimal and should focus more on increased intake of protein as well as lysine, vitamin D, and omega-3 according to a new Canadian study. Earlier research shows that magnesium, selenium, and Q10 are also important for muscle mass and strength.
Lack of vitamin D can impair your muscle function because it causes muscle cells to produce less energy, according to a study that is published in Journal of Endocrinology. The scientists use their study to argue that one can improve muscle function and reduce age-related loss of muscle strength in seniors by making sure they get enough vitamin D. If your muscles feel weaker during the winter period, you may want to consider taking a supplement.
Older people with a high intake of vitamin C appear to have healthier skeletal muscle than those with lower intakes, according to a new study from the University of East Anglia in England. This is an important discovery because our natural loss of muscle mass begins in our forties and starts to accelerate after we pass the age of 65 years. The phenomenon is known as sarcopenia and is one of the main reasons why older people become increasingly fragile and susceptible to disease. The authors behind the study believe that it is particularly important for middle-aged and older people to get plenty of vitamin C from their diets or by taking supplements. As a bonus effect, vitamin C also protects against infections and cardiovascular diseases, which also typically affect seniors.
