People with Parkinson’s disease are at higher than normal risk for osteoporosis and vitamin D deficiency. Regular weight-bearing exercise, exposure to sunlight, and a variety of supplements and dietary changes may be helpful in preventing osteoporosis.

A twice-weekly, 14-week program of intensive exercise has been shown to significantly improve the signs and symptoms of Parkinson’s Disease.¹Athletic training included resistance exercises in water to increase strength, as well as exercises increasing flexibility and balance.

There is substantial preliminary evidence that exposure to certain organochlorine insecticides (e.g., lindane [Kwell, Kildane, Scabene] and dieldrin [Dieldrite]) may contribute to the development of Parkinson’s disease.^{2, 3, 4} In California, death from Parkinson’s disease increased by about 40% in all Californian counties reporting use of restricted agricultural pesticides since the 1970s compared with those reporting none.⁵ Avoiding contact with pesticides and pesticide residues may be an important preventive measure for Parkinson’s and other diseases. Interestingly, consumption of the fat substitute olestra appears to increase elimination of certain organochlorine pesticides in the feces.^{6, 7} However, no scientific studies have tested olestra as a possible treatment or preventive measure against Parkinson’s disease. Moreover, since olestra consumption may be associated with other health risks, such as depletion of beta-carotene, people with Parkinson’s should consult with their doctor before consuming products containing olestra.
