Acorns have a high content of tannins, which makes them unsuitable for human consumption. But when raw they are so bitter that hardly anyone would eat them voluntarily.
Are acorns poisonous to humans?
Acorns are unsuitable for human consumption because they contain high amounts of tannins. If eaten raw, they can cause severe stomach and intestinal problems. However, watering, roasting or cooking can remove the tannins and make acorns edible.
