  • Vitamin E. Researchers have investigated antioxidant vitamins, especially vitamin E, for their effect on the brain. Some, but not all, studies have reported slower mental decline and lower risk for Parkinson's and Alzheimer's disease in people who ate large amounts of foods rich in vitamin E. Such foods include vegetable oils (particularly wheat germ oil), sweet potatoes, turnip greens, mangos, avocados, nuts, sunflower seeds, and soybeans. Vitamin E supplements, however, do not appear to be helpful for slowing disease progression or improving symptoms.



The Protective Effects of Nicotine and Coffee on Parkinson's Disease

Both smoking and coffee drinking have been associated with lower risk for PD. Researchers are attempting to discover if these substances protect nerve cells. One interesting study suggested that the early disease process in PD produces changes in the dopamine pathway that actually protects an individual from caffeine and nicotine addiction, so that fewer patients have a history of smoking and caffeine. Research is needed to determine why these toxic substances protect against PD.

Smoking and Nicotine Replacement. Cigarette smokers appear to have a 40% lower risk for Parkinson's disease, indicating some protection by nicotine. This finding, of course, is no excuse to smoke, but such protection may help researchers develop new therapies. Studies on nicotine replacement, such as gum or patches, have been conflicting, however, with some short-term studies reporting no benefits. A 2002 study suggested that nicotine replacement may help smokers with early PD, but not nonsmokers.

Coffee Consumption. Studies have indicated that the risk for PD in coffee drinkers is about 30% lower than for non-coffee drinkers. In one 30-year 2000 study of Japanese-American men, for example, coffee consumption was associated with a lower risk for Parkinson's disease and the more coffee they drank, the lower their risk became. Coffee and tea can reduce fluids by increasing urination, however, and so may increase constipation in PD.
