Kaufland offers mushrooms of vitamin D: how useful are these mushrooms?

Kaufland's retailer offers mushrooms for a while, the content of his vitamin D is 30 times that of conventional mushrooms when exposed to UVB light. The Stiftung Warentest has now seen the cultivation mushrooms and explains how sensitive they are.

Common deficiency of vitamin D

Last year it was reported that about 60 percent of children and adolescents in Germany had more or less depressed levels of vitamin D. In addition, a study showed that approximately half of people over 65 years of age are affected for vitamin D deficiency. In general, the supply of vitamin D in Germany is considered deficient. So it makes sense to enrich foods with vitamin D, as with some mushrooms?

Now it is also available in Germany

For years, German researchers reported on vitamin D-rich mushrooms sold in the United Kingdom and Ireland.

Only months ago, Swiss mushroom producers also launched mushrooms rich in vitamin D.

And, meanwhile, Kaufland's retail food chain in Germany also offers mushroom cultivation that is said to be high in vitamin D due to exposure to ultraviolet light.

But what benefits does the vitamin D fungus have?

Mushrooms light up briefly with UVB light

"30 x more than vitamin D" than conventional crops, "100 grams contain 125 percent of the recommended daily dose" – which promises the label of vitamin D mushrooms, which are exclusively on offer Kaufland, Stiftung Warentest informed on his website.

200 grams should cost two euros.

According to a retailer's message of the purchase, the mushrooms light up briefly with UVB light. According to the company, this increases the vitamin D content of mushrooms by a factor of 30 compared to conventional mushrooms.

Irradiation imitates a process in a wild state, since fungi produce abundant vitamin D under the influence of sunlight.

In conventional cultivation mushrooms, this does not happen almost because they do not grow in the light of day. Vitamin D is said to be compatible with the health of the bones and teeth.

The procedure was developed by doctor med. Paul Urbain, nutritionist at the University Medical Center of Freiburg.

Special mushrooms are produced by the company Pilzland in Lower Saxony.

The irradiation procedure works

The Stiftung Warentest has sent the fungi to the laboratory and reported on "test.de", if the mushrooms really contribute something to the vitamin D budget and if the specified levels of vitamin D are also correct.

According to the researchers, the experts determined the vitamin D content of mushrooms from seven different packages and determined that the irradiation procedure works.

The contents of vitamin D have an average of 9.6 micrograms per 100 grams, much higher than the levels of mushroom cultivation.

The sample analysis of common fungi revealed only about 0.3 micrograms of vitamin D per 100 grams.

According to the average value, the vendor's promise is that vitamin D fungi contains 30 times more than the so-called vitamin sun.

Vitamin D levels vary significantly

However, the levels of vitamin D vary significantly from one packet to a packet. The lowest level found in the mushrooms of a package was 5.3 micrograms of vitamin D per 100 grams.

By contrast, the highest content was 15.1 micrograms. This figure exceeds even the highest level that the EU has established for these new foods under the new European Food Regulation: ten micrograms per 100 grams.

An overdose of vitamin D mushroom lovers should not worry. Even the richest vitamin D mushrooms could eat according to the long-term merchandise test, without hesitation in various packages.

Since the levels of vitamin D in special mushrooms differ so much, the testers describe the precise vitamin D content in the 6.25 micrograms package per 100 grams as "very good".

In addition, mushrooms are not properly labeled: The new food regulations require that cultured fungi that have been treated with UV rays "are called to fungi treated with UV (Agaricus bisporus)."

But only the names "Vitamin D Mushrooms" and "Kulturchampignon" appear on the label.

The home gets vitamin D mainly through sunlight

"Especially now in the dark season, many people suffer a vitamin D deficiency. Because UVB content in sunlight is too low for their own vitamin D production on the skin," says doctor med. Paul Urbain.

"The Steinchampignons are an ideal way for vegetarians and vegans to simply and tastefully meet their vitamin D needs," says the nutritionist.

It is important to know, however, that humans only cover ten to twenty percent of the vitamin D requirement through their diet.

Observe significant amounts in fatty sea fish such as herring and salmon. For example, egg yolks and margarine, which can be fortified with vitamin D, provide smaller amounts.

Mainly, the person receives vitamin D, which is especially important for bones, through sunlight during the summer months.

Therefore, specialized societies recommend that, between March and October, two to three times a week, hands and arms are uncovered and without a sunscreen that exposes the sun: bright sun at noon, but it should have ; avoid it.

According to the Robert Koch Institute (RKI), half of the time in which otherwise a sunburn would be left unprotected, there is enough.

Those who spend more time in the sun should be protected from it, for example with sunscreen. The body can store a supply of vitamin D that is sufficient in most people to reach the dark season without symptoms of deficiency.

Taking supplements

Some people still rely on intake of vitamin D supplements. However, this should always be discussed with your family doctor.

However, these dietary supplements are not recommended for all people, experts say.

In addition, some of these preparations are not recommended, but even a risk, as the tests have shown.

And the drug commission of the German medical profession (AkdÄ) indicated that it can also lead to an overdose with supplements of vitamin D.

According to Stiftung Warentest, intake of vitamin D supplements may be useful for certain risk groups, for example, in whims or people over 65, who can no longer give a good vitamin D through the skin. (Ad)
