Vitamin D deficiency can lead to health problems
Vitamin D is vital for our organism. However, the vitamin is largely obtained from sunlight. However, especially in winter, the sunshine is not enough to meet our daily needs. Foods with vitamin D can help prevent a deficiency. Studies also point out that a deficiency in the vitamin promotes severe corona courses.
The need for vitamins and trace elements remains high
Eating habits and metabolism usually change with age. Seniors over 70 are usually no longer as physically active as they were in younger years, basal metabolic rate and calorie requirement decrease, Loss of appetite is widespread. But the Need for vitamins and trace elements remains high. In many cases, this leads to an insufficient supply of certain nutrients. So one study showed that about half of those over 65 have a vitamin D deficiency. Health experts recommend making up for this deficiency.
In the cold months there is not enough sun intensity
“About 80 percent of vitamin D is formed in the skin with the help of UV-B radiation from sunlight,” explains the German Geriatric Society (DGG) in an older press release.
It is therefore important to soak up enough sun in the warm months.
“However, the sun is not a reliable source: in the months of November to May, the sun’s intensity is insufficient in all of Europe“, according to the DGG.
Therefore, many people turn to dietary supplements. Elderly people in particular, especially those over the age of 70, often need vitamin D supplementation.
Use particularly high-quality food
You should consume one gram of protein per kilogram of body weight per day, recommends DGG President Jürgen Bauer.
“Due to the decline in physical activity that can usually be observed beyond the age of 70, the average calorie requirement falls in this phase of life,” said the doctor, according to a statement from the APA news agency.
“Nevertheless, the need for micronutrients such as vitamins and trace elements remains unchanged. Therefore, older people should use particularly high-quality foods when choosing their food. Otherwise, they face a deficit in this regard, ”warns the expert.
Vitamin D has a special position among vitamins.
“It is of particular importance for bones and muscles. As a result of skin aging, older people are particularly susceptible to a vitamin D deficiency, as their needs can hardly be met from natural foods – not even in combination with greater exposure to the sun, ”explains the expert in the agency report.

Taking vitamin D supplements
The intake of vitamin D supplements should always be discussed with the family doctor.
Such dietary supplements are not advisable for all people, recently warned experts from the Lower Saxony Chamber of Pharmacists.
And the Drugs Commission of the German Medical Association (AkdÄ) pointed out that there is also a Overdosing with vitamin D supplements can come.
Avoid weight loss
“The value of taking a multivitamin pill regularly has not been scientifically proven,” says Bauer.
It is also important for older seniors to ensure stable weight development.
“Beyond the age of 70, weight loss should be avoided if possible, since otherwise there is a risk of excessive loss of skeletal muscles and the occurrence of so-called sarcopenia (muscle wasting),” explains the geriatrician.
Diets could easily lead to malnutrition.
Sufficient protein intake
But muscle maintenance and building can also be implemented into old age. “A sufficient intake of protein is particularly important in old age, as this counteracts muscle breakdown. It can even be a little more protein than when we were younger, ”says Bauer.
“The official recommendation for seniors is an intake of one gram of protein per kilogram of body weight per day. The older adult does not have to use meat as a source of food, ”explains the doctor.
“Alternatively, high-quality dairy products and vegetable protein sources are available. A low-protein diet, on the other hand, can be seen as a real ‘muscle killer’. “
According to the expert, the necessary protein intake in sarcopenia patients could even be up to 1.4 grams per kilogram of body weight per day. (sb, ad)
