Alzheimer's Diets

A healthy Alzheimer's diet supports good blood flow to the brain, is low in saturated fat and cholesterol, and has the right balance of nutrients. In order for a person with Alzheimer's disease to function well, he must adhere to a balanced diet, whether it be a traditional diet or the Mediterranean diet.

Alzheimer's Disease

Alzheimer's disease is a brain disease that slowly progresses over time. It cannot be reversed. The main problem in Alzheimer's disease is the accumulation of abnormal proteins called plaques and tangles. As they increase, memory and thinking skills decrease. Many times, problem behaviors like crying for no apparent reason, wandering or agitation, occur. Eventually, carrying out simple tasks like getting dressed, making a bed or getting a drink are impossible.

Traditional Diet

Persons with Alzheimer's disease should eat foods rich in nutrients. Their meals must be well-balanced and include food from the four major food groups (healthy grains, fruits and vegetables, proteins, and dairy products). The diet should include variety, balance and moderation.
Even healthy older adults encounter changes in the way they eat as they get older: Sometimes food does taste or not smell the same as it used to. As people age, difficulties in chewing, swallowing and digesting food may occur. These problems may be more evident in people with Alzheimer's disease. Problems controlling appetite also may occur. People with Alzheimer's disease may overeat or not eat at all. They may only want to eat certain foods.
Vitamin or nutritional supplements may be needed if a person with Alzheimer's disease does not eat a healthy diet. However, consult a doctor before taking any supplements as they may interact with prescription drugs.

Mediterranean Diet

A Mediterranean diet may benefit people with Alzheimer's disease. In a study published in the September 11, 2007, issue of Neurology, those who most closely stuck to the Mediterranean diet had a lower death rate than those who did not. According to study author Dr. Nikos Scarmeas, eating a Mediterranean diet may help those with Alzheimer's disease have slower rates of mental decline, keep their daily living skills longer and enjoy a better quality of life.
The Mediterranean diet includes a high intake of vegetables, legumes, fruits, whole wheat breads and cereals, fish, especially fatty fish, monounsaturated fats like olive oil, and limited consumption of saturated fats, dairy products, meat and poultry. The diet also includes a small to moderate consumption of red wine.
