Omega-3 may reduce dementia

Research suggests that older people who regularly consume oils high in omega-3 are 60% less likely to develop dementia than those who do not. Omega-3s are polyunsaturated fatty acids believed to have a number of significant health benefits. The French-funded study examined the diets of more than 8,000 people over the age of 65. None had dementia when the study commenced, but after four years 183 had developed Alzheimer's disease and 98 had another type of dementia. The study also showed that participants who consumed fruit and vegetables every day reduced their risk of dementia by 35%.
