Can diet affect your Alzheimer's risk?
Does eating a lot of fish and few processed foods really help protect against Alzheimer's disease? A new study indicates that nutrition could play nearly as strong a role as other factors like age, number of years of education, and high blood pressure.
In the study published online in the journal Neurology, researchers measured the level of nutrients in the blood of nearly 300 seniors and found that those who had high levels of vitamin D and omega 3 fatty acids -- both found in salmon, tuna, and other fatty fish -- as well as vitamins C, E, and B -- antioxidants found in fruits, nuts, and green leafy vegetables -- appeared to have somewhat more protection against early symptoms of Alzheimer's. They were less likely to have cognitive difficulties, memory problems, and brain shrinkage -- an indicator of Alzheimer's -- than those who had low levels of these nutrients.
