Without vitamins, it looks bad for our body: They are among the essential nutrients that are involved in numerous metabolic processes. However, certain vitamins can only be processed by the body under certain conditions: If we take them without fats, fat-soluble vitamins have almost no effect. They are in these foods.
Fat-soluble vitamins vs. water-soluble vitamins: what’s the difference?
Fat-soluble vitamins need fats as a carrier medium because they are metabolized just like fats. So that the body can absorb and properly utilize them, fat-soluble vitamins should always be taken together with fats such as oils and butter. Unlike water-soluble vitamins, fat-soluble ones can be stored extremely well by the body. They accumulate particularly in the liver. A deficiency of vitamins from this category is very unlikely for this reason.
On the other hand, an excess, a so-called hypervitaminosis, is possible, albeit similarly unlikely due to the amounts of food that a person would have to consume to get into the toxic range. The only exception: Improper intake of vitamin preparations can also promote vitamin poisoning.
Fat-soluble vitamins A, E, D, K
The fat-soluble vitamins include vitamins A, D, E, and K. They each have different functions in the body.
Vitamin A supports the immune system, skin, mucous membranes, and eye health. Vitamin A can be ingested through animal foods or carotenoids. Carotenoids are a plant precursor of the vitamin; the body then forms it with their help. Carotenoids are plant pigments and are found in particular in fruit and vegetables with strong yellow, orange, red and green colors.
Vitamin E supports the immune system, has an anti-inflammatory effect, and is one of the antioxidants. The more unsaturated fatty acids are part of the diet, the higher the vitamin E requirement, since its antioxidant function protects the fatty acids from free radicals.
This vitamin is also known as the sunshine vitamin. It is formed in the skin through solar radiation and is particularly responsible for bone formation and a healthy bone structure. The immune system, muscles, and skin also need vitamin D. To prevent an undersupply, vitamin D sources should be increased in the diet during the winter months, such as oily fish.
Important for blood clotting and healthy bone formation and metabolism, vitamin K should also be part of a balanced and healthy diet. Deficiency is very rare as it is found in large amounts in many foods.
