Vitamin B17, or laetrile, is called the anti-cancer vitamin. It is an alternative treatment for cancer. Vitamin B17 works to reduce tumors and prevent metastasis or the spread of the cancer to other parts of the body. It kills cancer cells, strengthens the immune system and prevents cancer cells from developing in the future, this according to Cancer Tutor. Foods with a high content of Vitamin B17 are called nitrilosides. They include a variety of seeds, grains and nuts and sprouts and tubers as well as leaves and beans.
The apricot seed is the richest source of Vitamin B17. The kernel of the apricot can be cracked open to get to the seed. Other fruits with seeds rich with Vitamin B17 are peaches and plums as well as the seeds in cherries, prunes and nectarines. The tiny seeds in apples, grapes and those in berries, such as, strawberries, raspberries and blackberries, elderberries and wild crabapples are high in Vitamin B17. Keep in mind when purchasing bottled fruit preserves that the ones with seeds are also a good a source of Vitamin B17.
