There are bitter almonds and sweet almonds

Sweet almonds are sweet and flat, non-toxic, moisturize the lungs and relieve coughing and asthma, suitable for coughing, can be eaten raw.

Bitter almonds bitter substance is bitter amygdalin content in about 3%. This substance can be decomposed into cyanide under the action of enzymes, acids, cyanogen (CN-) into the human body after decomposition to generate hydrogen cyanide (HCN) toxic substances. Destroy the enzymes in human cells, so that they can not absorb the dissolved oxygen in the blood, resulting in the death of human hypoxia. Therefore, raw bitter almonds should not be eaten. (Note: Bitter almonds can be eaten after processing. Both kinds of almonds can be used as medicine.)

Fried or cooked almonds, most of the toxins have been destroyed, eaten generally will not be poisoned. If you soak raw almonds for a few days before processing until the bitterness is eliminated, you can make sure that they are safe to eat when cooked.
