Alzheimer’s disease affects nearly half of North Americans by age 85. The American Academy of Neurology forecasts that, unless preventive measures are developed, Alzheimer’s rates will nearly triple over the next four decades. Worldwide, Alzheimer’s rates will affect 100 million people by 2050.
While treatments for the disease remain unsatisfactory, scientific studies suggest that preventive strategies are now feasible. Evidence suggests that specific diet and exercise habits can reduce the risk by half or more. Although significant gaps in scientific knowledge remain, studies suggest that the same foods that are beneficial for the heart are also healthful for the brain and may reduce the risk of Alzheimer’s disease.
Dietary Guidelines
The seven dietary principles to reduce the risk of Alzheimer’s disease were prepared for presentation at the International Conference on Nutrition and the Brain in Washington on July 19 and 20, 2013.
The guidelines are as follows:
1. Minimize your intake of saturated fats and trans fats. Saturated fat is found primarily in dairy products, meats, and certain oils (coconut and palm oils). Trans fats are found in many snack pastries and fried foods and are listed on labels as “partially hydrogenated oils.”
2. Vegetables, legumes (beans, peas, and lentils), fruits, and whole grains should be the primary staples of the diet.
3. One ounce of nuts or seeds (one small handful) daily provides a healthful source of vitamin E.
4. A reliable source of vitamin B12, such as fortified foods or a supplement providing at least the recommended daily allowance should be part of your daily diet.
5. When selecting multiple vitamins, choose those without iron and copper, and consume iron supplements only when directed by your physician.
6. While aluminum’s role in Alzheimer’s disease remains a matter of investigation, it is prudent to avoid the use of cookware, antacids, baking powder, or other products that contribute dietary aluminum.
7. Include aerobic exercise in your routine, equivalent to 40 minutes of brisk walking three times per week.
