So-called fungi of vitamin D that have been treated with ultraviolet light should be healthy. Now Stiftung Wartentest has examined them.
Are D vitamins a promotional lie or really helpful?
Huge champions with glasses and hat advertise on Pilzland's website for the so-called Vitamin D mushroomsThey say they contain 30 times more vitamins than other mushrooms to maintain healthy bones and teeth.
Typically, people use sunlight to make the important vitamin through the skin, and the food is generally sparing. So are the mushrooms? Advertising lies or really useful?
Mushrooms actually provide higher levels of vitamin D, reported Stiftung Warentest after examination of seven samples. Mushrooms will not be boosted with artificial vitamin D, like some margarines but exposed to UV rays.
This mimics strong sunlight under which mushrooms form a lot of vitamin D. However, the values will vary considerably – between 5.3 and 15.1 micrograms of vitamin D per 100 grams of fungi, consumers report.
Also, the German nutrition society confirms the effect
The dose of additional vitamins can not be dosed well. They are also for the so-called new foodsaccording to which these irradiated mushrooms fall, according to the EU regulations, only ten micrograms of vitamin D per 100 grams are actually allowed. Consumers, however, should not be afraid of overdose, the testers explain.
Even a few packets a day will not hurt. The European Food Safety Authority (Efsa) recommends five micrograms of vitamin D per day – With mushrooms, this need can easily be covered so that consumers defend.
Even the German Nutrition Society confirmed at the request of the raw materials tester that the mushrooms can "significantly improve" the vitamin D status in healthy adults.
Testers advise on the preparation
However, not everyone necessarily needs additional vitamin D. Although according to the Robert Koch Institute in Germany, less than half of the children and 44% even less than half of adults are optimally supplied with vitamin. The rest of the population does not automatically suffer from a serious shortage.
This affects only 15% of adults and 13% of children and adolescents. You have one increased risk of infection with osteoporosis,
High risk groups can also meet their higher requirements for about 20 micrograms of vitamin D per day with mushrooms, the testers explain. However, they advise rather reliable dosages to be taken after consultation with a doctor. However, some supplements may also pose a risk.
