Vitamin B17 (laetrile/amygdalin) is thought to be effective as a treatment and prevention of cancer. Vitamin B17 aids the body in preventing abnormal cell growth. The vitamin was once readily found in fruit before man began to manipulate these foods to improve their bitter taste. Because of this crossbreeding, the vitamin is rarely found in the western world except in wild sources, fruit seeds, nuts and other unrefined natural foods.
Macadamia nuts are crunchy nuts with a high oil content. In addition to several other nutrients and minerals, such as iron and zinc, they are a good source of vitamin B17, especially in the raw form.
Elderberry is a red berry that grows in clusters. It can also be purchased in herbal or extract form. In addition to containing high levels of vitamin B17, elderberries are rich sources of vitamins A and C.
Apricot kernels as well as various other non-citrus fruit seeds are high in vitamin B17. The kernels can be purchased in the whole form or as a powder. The seeds of the fresh apricot can also be eaten along with the fruit to enjoy the vitamin B17 benefit.
Mung beans are small green legumes commonly used in eastern cultures. The beans are often allowed to germinate and then used as bean sprouts. They are easily digested and are a good source of vitamin B17 and protein.
