Following a diet rich in certain vegetables and lean-protein sources may slash your risk of Alzheimer's disease, according to a new study. The study also showed that diets low in high-fat dairy products and red meat were linked to lower risk of Alzheimer's.
The study involved 2,148 older adults (ages 65 and older), all of whom were free of dementia at the study's start. Over an average of four years, the study members regularly provided information about their diets. Analyzing the participants' dietary patterns, researchers found that high intakes of dark green leafy vegetables, cruciferous vegetables (such as broccoli and cauliflower), fruit, tomatoes, nuts, salad dressing, fish, and poultry were associated with reduced risk of Alzheimer's.
It's possible that specific nutrients found in these foods may protect against Alzheimer's disease, the study's authors suggest. For instance, omega-3 fatty acids available in fish may help prevent atherosclerosis and curb inflammation, while vitamin E found in nuts may offer antioxidant benefits. However, it's also likely that combining these foods may create a synergy of nutrients that could offer its own unique health effects.
