Despite this program, by the mid-1930s, white schools in the South were worth, per student, more than five times what black schools were worth per student (in majority-black Mississippi, this ratio was more than 13 to one).
There is no vitamin B17. The term is inaccurately applied to laetrile, a discredited cancer drug, and amygdalin, the natural substance from which laetrile is made. Amygdalin occurs in the seeds of apricot, peaches, and almonds.
All B vitamins are water soluble, meaning that the body does not store them. Vitamin B12 is an especially important vitamin for maintaining healthy nerve cells, and it helps in the production of DNA and RNA, the body's genetic material. Vitamin B12 works closely with vitamin B9, also called folate or folic acid, to help make red blood cells and to help iron work better in the body. Folate and B12 work together to produce S-adenosylmethionine (SAMe), a compound involved in immune function and mood.
