Whether for breakfast or for baking: Oatmeal has almost everyone at home. And even with the cheapest flakes, consumers don’t go wrong, as a review of the ingredients for the magazine “Öko-Test” (issue 10/2020) shows.

Oat flakes from the discounter at a price of 0.57 cents per 500 grams performed just as well as organic products for 2.40 euros per 500 grams. The testers examined a total of 24 products of the “tender” variety. Ten scored a total of “very good”, four with “good”, six with “satisfactory”, one with “sufficient”.

Three oatmeal products contain mold toxins

However, three products ended up with the “Unsatisfactory” rating also in the red area, including one from the organic segment. According to the “Öko-Test”, some of them contain nickel, mold toxins and contamination with mineral oil.

What is the problem with nickel? The metal has disrupted the reproduction and development of offspring in animal studies. The European Food Safety Authority (EFSA) therefore set a tolerable intake per day in 2018.

Two oat flake products examined by “Öko-Test” were so heavily contaminated with nickel that an adult with a body weight of 60 kilograms already exceeded the current value with a 50 gram portion.

“Öko-Test” rates the content of mold toxins in one product as “greatly increased”. The substances found are toxic to cells and could weaken the immune system.
