...Johns Hopkins University, Nina Simmonds, J. E. Becker and Elmer V. McCollum studied vitamin E, whose effect on sterility Drs. Herbert M. Evans and K. S. Bishop of the University of California discovered little more than a year ago (TIME, Feb. 15, 1926). The presence of vitamin E in the body permits fecundity; its absence causes sterility. It occurs in lettuce, wheat germs, alfalfa, egg yolks, liver...
Marrow, Alfalfa. "One of the greatest services a man could render the world today would be the formulation of a recipe for an appetizing dish of bone marrow. Next would come an introduction of alfalfa as an item of our menus. Alfalfa is the richest of all foods in vitamin and iron."-Professor Louis S. Davis, Indiana University...
There are only five vitamins known. Vitamin A stimulates body growth; Vitamin B prevents neuritis (beriberi is a characteristic disease following deprivation of this essential) ; Vitamin C prevents scurvy; Vitamin D prevents rickets; and Vitamin E must be present if an animal is to be fecund. All of these vitamins are extremely unstable chemical compounds. None of them has been definitively examined, yet their reactions on living animals are well-known and they can be isolated and handled as unseen principles...
Heretofore the biochemists have considered that all the vitamins are derived from plants, although it is well-known that ultraviolet light can energize cholesterol and phytosterol (cholesterol is a constituent of animal cells, phytosterol, of plant cells) to behave like Vitamin D as a rickets-preventive. It might be that the ultraviolet light actually created Vitamin D. Vitamins found in milk, cod liver oil and fresh flesh have been supposed to have come ultimately from plants that carried such vitamins...
...Heifer Jessie's first stomach that the Pennsylvania State scientists believe they will find Vitamin B manufactured. Each day they will scoop a trifle of predigested vitamin-less hay through the cow's little window and feed it to dieted rats. If the rats do not get neuritis, Jessie does make Vitamin B. If they do get neuritis, then the experiment will have been usefully foolish. It will have closed one more needless door of scientific research...
