Some Fruit Seeds Contain Cyanide
By Chad Upton | Editor
Seeds from peaches, black cherries, apricots and apples contain a compound called amygdalin. Your body metabolizes amygdalin as hydrogen cyanide, which can make you very sick and even kill you (in large doses).
Hydrogen cyanide is lethal because it impedes blood from carrying oxygen, which is of course a critical function of blood.
The pits and seeds from cherries and apples aren’t a huge concern since it would take an unreasonably significant quantity of those to cause you harm. However, you should be more aware of the dangers of peach and apricot seeds if you like to eat them.
If you’re just consuming the fruit, there is nothing to worry about; however, some people buy bags of apricot seeds, or other forms of amygdalin, as a treatment or preventative treatment for cancer. It is marketed under the name Laetrile and “Vitamin B17” although there are many studies that prove it is not effective at treating cancer, not to mention the increased chance of cyanide poisoning.
A fatal dose of cyanide can be as little as 1.5 mg/kg of body weight. Since an apricot kernel contains approximately 0.5 mg of cyanide, consuming 150 seeds in a short period of time could be lethal to a 50 kg (110 lb) person.
It’s not just fruit seeds, there are other foods that contain cyanide too. Cassava, also known as tapioca, contains two forms of cyanide and should not be eaten raw. It is rendered safe for consumption by the process of soaking, cooking or fermentation.
There are many people who consume these foods in small doses without issue; you can buy bags of apricot kernels from Amazon or health food stores. If you do buy some, heed the serving suggestion and warning on the package.
