Bitter-tasting nuts can have negative health consequences. We explain how you should deal with bitter nuts and which regional nut varieties are best for consumption.
Bitter nuts can be harmful to your health. They may contain mold or toxins. If the nuts are also stored warm and moist, they can release so-called mycotoxins. These are certain mold toxins that are produced during the metabolism of mold. A distinction is made between different mycotoxins, including aflatoxin, for example.
If nuts are discolored or have a bad odor, do not eat them. But beware, the mold in mycotoxins can sometimes be recognized neither by its appearance nor by its smell. However, a bitter taste or discoloration are signs of mycotoxins.
This is why bitter nuts can be bad for your health
According to the Federal Office for Consumer Protection, mycotoxins can affect the kidneys or liver, cause diarrhea or vomiting, weaken the immune system and, in the worst case, even promote the development of cancer. Therefore, you should definitely spit out bitter nuts immediately.
According to the agency, pistachios and peanuts are primarily affected by mycotoxins. Occasionally, however, the mold fungi can also be detected in walnuts and almonds. Therefore, you should be particularly careful with these four strains. Also make sure to always store nuts in a dry and cool place.
Nuts are healthy – if they don’t taste bitter
Nuts are a healthy snack in and of themselves, as long as they don’t taste bitter. They are mainly made up of fat and protein, which are good for the cardiovascular system. At the same time, they contain important dietary fibers that have a positive effect on digestion. However, many nut varieties have a poor ecological balance due to their long transport routes.
Nuts that are also grown in Europe include walnuts and hazelnuts. Almonds mostly come from California, but there are also Italian or Spanish ones. Therefore, for the sake of the environment, you should pay attention to the country of origin of the nuts. An organic certification guarantees you organic cultivation without the use of chemical-synthetic pesticides. With the Fairtrade seal, you also support decent working conditions and fair wages.
