Why are vitamin D-containing foods important?
Vitamin D is involved in countless regulatory and building processes of the human organism. Although referred to as a vitamin, vitamin D, according to current knowledge, the character of a hormone. Especially the immune system is dependent on vitamin D. However, vitamin D in combination with calcium also has an influence on bone formation. Mostly vitamin D is formed by UV radiation in the skin.
In autumn and winter, the angle of the sun in the northern hemisphere does not reach the correct level, which allows vitamin D formation in the skin under the influence of the sun. The supply of vitamin D-containing foods is therefore even more important in winter than during the summer months.

Vitamin D has many functions in the body, but not all are researched yet. Studies report a possible association between vitamin D deficiency and increased cancer risk. Scientific studies link vitamin D deficiency, among other things, to an increased risk of cancer. Also, multiple sclerosis, various forms of rheumatism, as well as various types of inflammatory bowel disease may be associated with low vitamin D levels.
Vitamin D is stored if enough is produced during the summer months. Crucial for the evaluation of the vitamin level is the proportion of 25-hydroxy-vitamin-D3 in the blood serum. Reasonable levels start at 50 ng / ml (or 125 nmol / l), ideally between 50 and 80 ng / ml (125 to 200 nmol / l). The vitamin D stores can supply the body for a while, but not throughout the winter, which is why supplementation or dietary intake is highly recommended.
Daily requirement of vitamin D.
Importantly, people with dark skin have an increased need for vitamin D when in the Northern Hemisphere. The darker the skin type, the more sun the body needs to produce Vitamin D, as it provides natural protection to the skin from the sun and inhibits vitamin D production.
In the northern hemisphere, the intensity of the radiation is too weak, especially in the winter months, to penetrate the darker skin and form vitamin D.
Studies also indicate that heavy obesity reduces the release of vitamin D into the blood.
There is hardly any vital substance in which the recommendations for the daily requirement are discussed as controversially as with vitamin D. Lately, the daily requirement has been repeatedly corrected upwards. For example, while higher levels are particularly recommended in the US, especially in the winter months, recommendations in Europe remain more conservative.
The following are the minimum recommendations according to European requirements:
Infants around 400 I.E. per day / premature baby around 1000 I.E.
Adults 800 I.E. per day.
In the United States, some 1,000 to 2,000 I.E. recommended per day. This is especially true in old age with a tendency to osteoporosis and in winter. Older people often have low vitamin D levels because they are barely in the sun. The ability to produce vitamin D in the skin may also decrease with age. Again, daily dosages of 1,000 I.U. Recommended upwards.
THE RIGHT NUTRITION OF MORBUS CROHN
The right diet for Crohn's disease
Those suffering from Crohn's disease can control the inflammatory processes through nutrition. This is especially important to support the healing process in the course of a disease. However, chronic inflammation within the digestive tract often makes adequate nutrient delivery in Crohn's disease difficult. Frequently, areas of the small and large intestine are affected.
This limits the intake of many nutrients. In addition, the inflammation associated with painful symptoms such as abdominal pain and diarrhea. In order to increase your own well-being, you should therefore pay attention to a healthy and balanced diet, which also supports as long as possible a relapse-free phase (remission). Our nutritional medicine practice specializes in digestive diseases. There is no unity solution. Therefore, we rather look individually with our consultants, which nutrition does you best.
Crohn's disease often causes malnutrition. Malnutrition is mainly caused by chronic inflammation of the small and large intestine. This has many causes. On the one hand it comes to absorption disorders in the inflamed areas of the digestive tract and at the same time caused by the healing process increased nutrient requirements. On the other hand, many patients suffer from loss of appetite due to the painful symptoms that are exacerbated by food intake.
Therefore, in patients with Crohn's disease, great importance should be attached to adequate nutrient supply. Mostly an increased energy supply is necessary, but also a high intake of micronutrients.
