Foxx_240216Alzheimer’s disease currently affects around five million people within the U.S. over the age of 65—thankfully, the ultimate Alzheimer’s diet plan includes a helpful list of foods to eat and foods to avoid. An Alzheimer’s diet plan is particularly important since Alzheimer’s is an unpleasant form of dementia that strips away memory, identity, and ability to function during the most vulnerable years of late life.

Until a cure is devised, preventing Alzheimer’s emergence and slowing its advance remains the only option. Fortunately, there is no shortage of studies, surveys, and analysis describing what you can eat and drink to improve your chances of escaping Alzheimer’s.

Your diet is believed to affect Alzheimer’s and it all boils down to nutrition. Alzheimer’s is currently suspected of being caused by a buildup of damaging plaques in the brain and oxidative stresses. This means that nutrients with antioxidant properties, or those capable of protecting neural tissue, are the best bet for minimizing the risk of Alzheimer’s dementia:

  • Vitamin A and beta-carotene: This is a pair of antioxidant nutrients that are known to be reduced in Alzheimer patients. Additionally, laboratory tests have found that the combination can keep amyloid plaques from forming—one of the suspected causes of the dementia. Lastly, beta-carotene is associated with improved memory and mental tasks and exercises are also a means of helping stave off Alzheimer’s.
  • Vitamin C: Another antioxidant with the ability to keep plaques from forming. Unlike vitamins A and beta carotene, this result has been seen both in vitro (petri dish) and in vivo (in the body).
  • Zinc: Zinc is known to reduce the presence of plaque signs in the hippocampus section of the brain and in mice it’s been found to reduce memory decline. Additionally, cognitive decline in Alzheimer’s patients has an association with zinc deficiencies, though it is unclear whether this is correlation or causation.

Other nutrients, such as the B vitamins or iron are also reported to have antioxidant or other protective effects in the brain. However, the body of research on them is much less conclusive than the three listed above.

Foods to Eat If You Have Alzheimer’s

With the above in mind, consider adding or increasing the following foods in your diet so that you can be sure to get the proper amounts of vitamins A and C, zinc, and beta-carotene:

  • Sweet potatoes
  • Carrots
  • Dark, leafy greens
  • Melons
  • Grass-fed beef
  • Dark Chocolate
  • Chickpeas
  • Cashews
  • Tuna

Foods to Avoid If You Have Alzheimer’s

Fats and alcohol are the main things you should avoid when trying to minimize your Alzheimer’s risk; however, this isn’t quite cut-and-dry. With fats, the current research suggests that relative levels of different types of fat—rather than actual intake amounts— that determine your risk. Keeping your mono or unsaturated fat intake higher than saturated has been shown to improve cognitive function, while the reverse results in worse function. With this in mind, try to limit or eliminate the following in your diet:

  • Butter or margarine
  • Red meat (no more than four servings per week)
  • Cheese
  • Pastries
  • Fried/fast food
  • Alcohol (see below)

With alcohol, two or fewer glasses per day seem to have a protective effect, but more raises your risk instead. It is advisable then that you either keep your drinking to a minimum, or abstain entirely.

A Word about Supplements

Vitamin supplements may be useful alongside dietary changes, but only in certain circumstances as advised by your doctor. Supplements are highly beneficial as a way to correct any nutritional deficiencies you may have, but if you are eating a proper and balanced diet they will have minimal, if any, effect.
