Dangers and contraindications of eating acorns
Are acorns edible or are they toxic?
Not all acorns are edible, but it depends on the tree they come from. Within the same species, there are trees that produce sweet acorns and others that make them bitter.
However, this fruit is very beneficial for people with obesity, type 2 diabetes and bad cholesterol, so it does not deserve to be wasted.
What toxic components do acorns have?
Acorns contain many tannins, responsible for their bitter and astringent or rough taste. Tannins have properties to lower cholesterol and sugar. However, in excess they are very indigestible, can cause digestive irritations and vomiting.
You have to learn to cook acorns properly to reduce their tannins a little.
It is recommended to look for those trees that produce sweet acorns, which will also be the ones with the lowest tannin content. Sour acorns have a higher content of tannins (bitter substances) and can cause poisoning in case of important ingestion.
Effects of tannins in acorns (acorn poisoning)
The tannins of the acorns that are found in all parts of the plant, stand out responsible for the harsh taste of the fruits. In high doses, tannins can cause intestinal disorders and irritation of the digestive mucosa. This is because the action of these components consists on drying out the digestive secretions, blocking mucus secretion.
This property is useful for stopping diarrhea, but it is very harmful to the stomach.
Tannin poisoning causes vomiting and gastritis. This is the reason why acorns must be eaten with caution.
