CHEWING
From ancient times, the virtues of chewing have been widely recognized. Chewing contributes to more efficient use of nutrients, gives stronger energy, and makes the food sweeter to the taste. It also makes food go further and hence contribute to increased savings, reduced energy consumption, and a healthier planet.
When AIDS first appeared in 1981, macrobiotic educator Michio Kushi began recommending thorough chewing as a key dietary measure to help prevent the development of immune deficiency. He noted that the yang, contractive properties of saliva, which is promoted during chewing, could help neutralize the extreme yin, expansive quality of the AIDS virus.
• Saliva Inhibits HIV - Saliva contains substances that prevent the AIDS virus from infecting white-blood cells.
. In a study, dental researchers tested saliva from three healthy men, 35, 40, and 42 years old. Tests indicated the men were not carriers of the AIDS virus and were not known to be at high-risk for infection. In laboratory dishes, the men’s saliva prevented the AIDS virus from infecting lymphocytes, a type of white-blood cell that is among the immune system cells attacked by the AIDS virus in the body.
The researchers said the finding might help explain why no cases have been documented in which the AIDS virus was transmitted from person to person through saliva such as through kissing or sharing toothbrushes. The scientists concluded that saliva is well known to contain substances that kill bacteria and funguses and so might also be able to block the AIDS virus.

• Chewing and Cancer Risk - An Indian cancer researcher concluded that thorough chewing lowered the risk of cancer. “The proper chewing of meals ensuring that mucous-rich saliva mixed with the food seemed to be protective factors.” Cancer also appeared to more prevalent in south India where white rice and considerably more fat, oil, and spices are used in cooking than in north India where whole-grain chapatis and thick dahl made with lentils are the staple.

• Chewing Prolongs Life in a Concentration Camp - In his book on the powers of food, especially the power of chewing, Lino Stanchich, a leading macrobiotic teacher, describes how his father survived a concentration camp in Serbia during World War II by very thorough chewing.
