Bitter Apricot Kernels are particularly high in Vitamin B17 which is known for it's ability to aid in cancer prevention.  They are also very high in antioxidants and help with inflammation and to fight free radical damage.   You should only eat about 3 kernels per day (eating too many of any kind of nut isn't good for you as each nut contains it's own natural toxins to protect them in the wild).  A few is great, too many not so good.
