Why are walnuts a bit bitter?

It may be normal for walnuts to be a bit bitter, or they may have gone bad, and it is usually necessary to clarify whether they can still be eaten. Eating walnuts properly has certain benefits, but if eaten improperly, it will cause certain harm to the body.

1. Normal phenomenon: Walnuts may be a little bitter because the outer skin of the walnut kernel is not removed cleanly during consumption, which usually affects the normal taste and may show a slightly astringent or slightly bitter taste. The aerobic substances in the long term will not be damaged and will not interfere with the absorption of nutrients.

2. Deterioration: If the walnuts taste a bit bitter, it may be because the walnuts are moldy and have been stored in a humid environment for a long time. This is usually accompanied by the growth of pathogenic microorganisms, which will cause the destruction of the nutrients in the walnuts and the taste of the walnuts, causing them to taste bitter. It is generally necessary to avoid eating food after it has gone bad, otherwise it will cause damage to the gastrointestinal tract, possibly gastrointestinal inflammation, and easily cause symptoms of abdominal pain or diarrhea. If eaten in large quantities, it may also cause poisoning.

There are some benefits to eating walnuts in moderation. Walnuts are rich in trace elements and amino acids, which can supplement nutrients and help increase the activity of brain cells.
