Some investigators think that one of the contributing factors to old age is the toxins absorbed from putrefaction in the large intes- tine. The toxins affect the arteries causing the hardening of the arterial walls. The bacteria of putrefaction work best in an alka- line medium. A Russian physiologist, Metchnikoff, conceived the idea of introducing an acid into the large intestine. He thought this would check putrefaction and possibly postpone old age. He observed that Bulgarians who used a great deal of sour milk, live to a greater age than other people. He knew that the acids from most foods are neutralized before they reach the large intestine, but that unlike ordinary sour milk the acid in Bulgarian milk does reach the large intestine. Different strains of bacteria in milk cause the two different reactions. Bacillus bulgaricus and bacillus acidopholus which is a related strain of microorganisms, have been cultivated in America. Experiments are now being made with acidopholus milk to determine whether it does have a beneficial effect although there is as yet no definite proof. People should not become faddists in eating.
