Soy drinks: According to Stiftung Warentest, around every third drink is deficient

Soy drinks: Stiftung Warentest rates every third product as "deficient"

Herbal alternatives to cow's milk have been booming for years. Products made from soy, in particular, are often used. The Stiftung Warentest has now taken a closer look at 15 soy drinks. Every third of them went through a lot during the test.

Alternatives to cow's milk

Some people rely on plant-based milk alternatives because they want to eat without animal products if possible. For others, health issues or intolerances, such as lactose intolerance, play a role. Soy milk is considered a particularly recommended alternative to cow's milk. But not all soy drinks are good, as an investigation by the Stiftung Warentest showed.

Soy drinks tested in the natural flavor

"Soy drinks are the number one milk alternative and are considered healthy," wrote the Stiftung Warentest in a press release.

However, some of these drinks contain pollutants or germs that can harm health.

This was shown in an investigation by the Stiftung Warentest. The testers tested 15 natural flavored soy drinks with and without calcium enrichment, including well-known brands such as Alnatura, Alpro and dm. Twelve of them were certified organic.

Almost every second soy drink performed well. But every third was deficient.

Very heavily loaded with nickel

As the testers write on their website, a glass of soy drink provides almost as much protein as whole milk.

But: "The super image of the bean has been scratched," says the test report. Six of the soy drinks, all with an organic label, were heavily to very heavily contaminated with nickel.

As the experts explain, it has been shown in animal experiments that high nickel consumption damages reproductive ability and can lead to eczema in highly sensitized people.

According to the information, nickel finds mostly have a natural origin: the soy plant therefore picks up the heavy metal from the ground and stores it.

However, it can also get into food through production processes and air pollution. The test showed that the organic seal does not protect against high levels of pollutants: all soy drinks with a high nickel content had one.

Chlorate was also a problem. It appeared in health-threatening quantities in a soy drink from the Asian market.

According to the testers, chlorate contamination could have occurred during the production process.

A drink was inedible

The organic soy drink Calcium from dm even turned out to be inedible. The cause was the very high level of cellulosimicrobium cellulans, which could lead to discomfort in a sensitive intestine.

The testers do not recommend consumption. The Stiftung Warentest informed the provider about the find during the test phase. dm took the affected batch out of sale in April 2018.

Good taste and full of valuable nutrients

A total of seven of the 15 soy drinks in the test are good choices. They contain no harmful amounts of pollutants, are good in taste and provide valuable nutrients. They cost between 95 cents and 2.34 euros per liter.

The exact test results can be downloaded for a fee from the Stiftung Warentest website.

But one thing can be revealed: The “Bio Soja Drink” from Berief has won the test for 1.29 euros per liter. And the cheapest "good" soy drink comes from the discounter Lidl (0.95 euros). (ad)
