New in the supermarket: Vitamin D-mushrooms – what Stiftung Warentest says?

In the dark, the sun arms of light and Season between October and March, Vitamin D levels will decrease in many people to a Minimum.

Listlessness, fatigue, pale skin, and aching bones – these are the consequences of Vitamin D deficiency.

However, Vitamin D-mushrooms are a lack of really useful? And hold the mushrooms what they promise?

Vitamin D mushrooms are available in Germany

Only the UK, Ireland and Switzerland – and now Germany: Since a few weeks, the food-retail chain Kaufland brown mushrooms that were treated in the laboratory with a short-term UV-light irradiation.

Results: The irradiated mushrooms to contain 30 Times more Vitamin D than conventional culture champignons “100 grams of containing 125 percent of the recommended daily dose of Vitamin D” – the label of the Vitamin-D-mushrooms promises, at least.

Novelty: "Vitamin-D-Pilze" in the country of purchase.

The company’s mushroom country breeds this type of mushrooms in a special laboratory where the mushrooms are treated with ultra-violet radiation.

Objective: The irradiation mimics the sun light as in nature – the mushrooms make plenty of Vitamin D. When it comes to commercial breeding of mushrooms is not almost never, since they grow under natural light.

The Stiftung Warentest says to the UV-mushrooms

"The irradiation procedure works tatsächlich", according to Stiftung Warentest. In seven different samples of an “average Vitamin D was measured-value of 9.6 Mikrgramm per 100 grams” – considerably higher than cultivated mushrooms. The value was 0.3 micrograms per 100 g.

Conclusion of the Stiftung Warentest: “Based on the average value of the promise of the provider’s true, because Vitamin D-mushrooms 30 times more of the so-called sun vitamin.”

However, the review team noted that that the Vitamin D contents of the pack vary to pack.

A pack of exceeded the of the European Novel Food regulation lays down the maximum value of 10 micro-grams per 100 grams.

Therefore, the manufacturer should declare the product according to the Novel Food regulation, rather than “UV-treated mushrooms”, instead of “Vitamin D mushrooms”.

“An Overdose of Vitamin D do not need to worry about mushroom lover but,” Stiftung Warentest.

UV-mushrooms: Our conclusion

Mushrooms are naturally rich in Vitamin D. Since we are mainly cultured mushrooms will have seen in their growth phase is never natural light from the sun, however, are in retail, the Vitamin D-mushrooms are a good Alternative.

100 g of these mushrooms, which cover the daily need in Vitamin D, are about a half a pack or a handful of mushrooms.

Important in the preparation of the mushrooms in the fat to fry. Because only a Portion of fat the body takes the Vitamin D.

However, you should know that we take in 80 to 90 percent of Vitamin D solely through the direct sun light on our skin, and only 10 to 20 percent of Vitamin D through food.

This means in reverse conclusion: Vitamin D deficiency, we can NOT compensate alone with Vitamin D-mushrooms, or other Vitamin D-rich foods. You can only act in a certain way to be supportive – as well as Vitamin D supplements.

Knowledge of good Sidefact: Should you be the rays of the sun exploit in Winter, without gloves or hat. Because we take especially on the wrists, on the head and in the face of the most Vitamin D, because our skin is thinnest.
