Alzheimer's disease is a progressive condition that damages areas of the brain such as memory, intelligence, judgment, language and behavior. Although its cause is still unknown, many experts believe multiple factors are involved. One suspected cause may be a lack of a balanced diet. The experts believe that a diet rich in vitamins and minerals may help decrease the risk of developing Alzheimer's disease.
Antioxidants
Antioxidants such as vitamins E and C are beneficial in decreasing the risk of developing Alzheimer's disease. Antioxidants help eliminate harmful free radicals from the body to help prevent disease and infection. Vitamin E is a fat-soluble vitamin found in vegetable and nut oils as well as in whole grains and spinach. Vitamin C is a water-soluble vitamin found in citrus fruits such as oranges and grapefruit as well as in tomatoes, spinach and red peppers. The skins of dark berries also provide a valuable source of antioxidants in the diet.
Vitamin B12
Vitamin B12 is needed for proper red blood cell formation, neurological function and DNA synthesis. Vitamin B12 and folic acid lower the level of amino acid in the blood, which is often elevated in people with Alzheimer's disease. A deficiency of vitamin B12 causes an accumulation of homocysteine in the blood. Some studies have shown a correlation between elevated homocysteine levels and the incidence of Alzheimer's disease, dementia and cognitive decline. Low-fat milk and milk products, fortified breakfast cereals, fish, red meat, poultry and eggs are all sources of vitamin B12.
Calcium and Sodium
Adequate calcium is needed in the diet for a healthy metabolism. An imbalance of calcium may also trigger a number of metabolic disorders such as hypoglycemia, depression and bipolar disorder. Calcium works with magnesium, phosphorus, and vitamins A, C and D. Sodium works with potassium to maintain healthy metabolic function. A deficiency or excess of calcium can result in mental confusion, personality changes, severe mental dysfunction and dementia.
Fatty Acids
Essential fatty acids such as those found in alpha linolenic acids, borage oil and omega-3 fatty acids found in fish can decrease the risk of developing Alzheimer's disease. Omega-3 fatty acids have anti-inflammatory properties that can increase cognition, including learning and memory skills. Omega-3 fatty acids are found in mackerel, lake trout, herring, sardines, albacore tuna and salmon.
Niacin
Niacin is important for maintaining cellular metabolism or oxidative stress. Severe niacin deficiency, or pellagra, can cause delirium, which could lead to dementia. Niacin is found in beef liver, lean meats, poultry, fish, eggs, cheese, soybeans, nuts, whole grains, green vegetables, beans and low-fat milk.
