Foods That May Help Prevent or Slow Down Dementia

Scientists have developed balanced diets that include healthy foods to help slow down or even prevent the onset of dementia and Alzheimer’s disease.  However, the composition of the diet should take place strictly under the supervision of a specialist after the examination. The Mediterranean and MIND diets are the two best diets to help prevent or worsen dementia symptoms.

These diets contain certain brain-boosting foods that can help prevent dementia, such as:

  • Leafy greens;
  • Fruits and vegetables;
  • Nuts and Olive Oil;
  • Protein;
  • Snacks;
  • Fish;
  • Berries and Seeds.

Some of the main factors that provoke the development of dementia and Alzheimer’s disease development are genetic predisposition, environmental influences, surgery, and lifestyle, including diet. Also, we must say that patient conditions such as hypertension, heart disease, diabetes mellitus, and obesity can lead to cognitive decline.

In this article, we will look at what diets prevent dementia and Alzheimer’s disease, as well as how individual products of these diets affect the human brain and overall well-being.


Mediterranean Diet 

The Mediterranean diet is high in fruits, vegetables, legumes, and grains, moderate in oily fish and dairy products, and low in meat, sugar, and saturated fat.

This diet reduces levels of amyloid and tau proteins. This diet contains foods that can help reduce the likelihood of developing dementia, fight memory loss, and prevent the appearance of the stroke, type 2 diabetes, and cardiovascular disease.


MIND Diet 

This type of diet is a combination of two diets such as the Mediterranean and DASH. This combination represents a considerable benefit and aims to prevent and slow down the deterioration of brain function.

Studies show that this combination of diets reduces the risk of Alzheimer’s disease by 53% in those who adhere to it.

Experts initially recommended this diet for healthy older adults. Still, in 2018 it was revised by experts and expanded so that it can be consumed by people in their octogenarians recovering from a stroke.

Let’s take a closer look at the best foods for dementia patients to eat that are contained in these diets.

Leafy greens

Leafy Greens

A study on the effect of greens on the brain showed that the brains of people who consumed a serving of green leafy vegetables did not lose their capacity as quickly. Their thinking skills and memory remained active much longer than those who did not consume greens.

Eating greens has also been shown to be associated with slower cognitive decline in older adults due to the neuroprotective effects of certain nutrients.

Thus, the researchers concluded that eating a daily serving of greens contributes to brain health.

Fruits and vegetables

Fruits and Vegetables

Eating plenty of apples, bananas, and oranges can also be the best foods for dementia patients to eat.

Daily consumption of these types of fruits protects the brain’s neuronal cells from neurotoxicity, which is caused by oxidative stress. It is vital in reducing the risk of neurodegenerative disorders such as dementia and Alzheimer’s.

Some vegetables such as broccoli, cauliflower, and Brussels sprouts are rich in B vitamins and carotenoids. All of this can reduce the level of homocysteine – amino acids, leading to decreased cognitive functions, dementia, and brain atrophy.

Nuts and olive oil

Nuts And Olive Oil

Olive oil and nuts contain low-saturated fats. It helps keep arteries healthy. These foods are also rich in fiber, vitamin E, and minerals. A diet rich in olive oil and nuts reduces inflammation. It helps fight beta-amyloid plaques, a common cause of dementia. In addition, these products improve the condition of blood vessels and improve cerebral circulation.




Actually, protein is also part of the dementia prevention diet. The protein diet has the following recommendations:

  • Eating beans once every few days;
  • Poultry meat – twice a week;
  • Fish – once a week.

As an option, you can make chili from beans and turkey and consume it for several days.

All of these foods are high in protein and low in saturated fat, so this diet is good enough to support overall health, especially brain function.




Snacks are also a great addition to most diets. As for snacks, you need to eat nuts and berries. You can consume them in small amounts throughout the day between meals.

Nuts and berries are good for brain function and overall health. For example, berries such as blueberries and strawberries, in addition to helping the brain work, can also slow the onset and aggravation of the condition associated with Alzheimer’s disease.

Sea and seafood

Fish and Seafood

One of the common causes of dementia and the development of Alzheimer’s disease is the poor condition of the brain vessels. Studies have shown that eating fish improves the general condition of the vessels, as well as the tiny vessels of the brain. This food is what is needed to prevent the development of dementia.

Experts advise eating 2-3 servings of fish per week, which will help keep the brain healthy for as long as possible.
Berries And Seeds

Berries And Seeds

Let us consider in more detail the effect of berries and seeds on the human body.

Berries such as raspberries, blueberries, blackberries, and cherries contain a flavonoid called anthocyanin. This flavonoid helps stop the progression of brain damage caused by free radicals.

These, as well as most other berries, contain antioxidants and many vitamins. This dementia prevention diet helps reduce inflammation and keep the brain functioning properly.

In terms of seeds, flax, pumpkin, and sunflower seeds are rich in antioxidants as well as nutrients like vitamin E, choline, zinc, and omega-3s.

All this slows down the deterioration of cognitive functions, such as memory, logic, and concentration.

These seeds can be consumed just like that and added to salads and desserts, for example, laying them in puddings and muffins.


Bottom Line 

A properly selected diet can prevent the deterioration of the brain, protecting it from destruction. However, only a doctor can give precise recommendations about a prevent dementia diet

  • Can you lose weight on a Mediterranean diet?

Yes, this diet is excellent in helping patients lose weight. Studies have repeatedly confirmed that the Mediterranean diet promotes weight loss more than other diets, such as low-fat diets.

  • What are the risks of the Mind diet?

Mind diet does not pose a health risk to patients. However, before the patient decides to follow this diet, he should consult a doctor to adjust its ingredients and the amount of food consumed.

  • What shouldn’t you eat with dementia?

You should consult a doctor on the list of prohibited foods, but it is not recommended to eat:

  1. Animal fats (margarine, poultry skin);
  2. Offal (liver, kidneys);
  3. Fat sour cream and milk;
  4. Mayonnaise and ketchup;
  5. Pastry, white bread, and sweets.
  • Can I drink wine when I follow the Mind diet?

Yes, you can drink wine while on a diet. Red and white wine have been shown to benefit the brain and may even protect against the onset of dementia and Alzheimer’s. For example, experts allow to drink wine, but not more than one glass a day, with the Mind diet.

Just such an amazing staff that makes you feel like part of their family. I’ve been going there for over 5 years now... and each visit I get the very best care and treatments that I have ever received in the 20+ years that I’ve been dealing with severe debilitating migraines. Since i started seeing them the number of my migraines has dropped from 15-20 a month to 2-3 every 3 month. I highly recommend them …they will change your life!read more

Dr. Askari was very kind and explained everything so I could understand. The other staff were nice as well. I would... have gave 5 stars but I was a little taken aback when I checked in and had to pay 600.00 upfront. I think that should have been discussed in a appointment confirmation call or email just so I could have been more

I was obviously stressed, needing to see a neurologist. The staff was so patient and Dr. Ansari was so kind. At one... point he told me to relax, we have time, when I was relaying my history of my condition. That helped ease my stress. I have seen 3 other neurologists and he was the only one who performed any assessment tests on my cognitive and physical skills. At one point I couldn't complete two assessments and got upset and cried. I was told, it's OK. That's why you're here. I was truly impressed, and super pleased with the whole experience!read more

Since my first post my thoughts have changed here. It's unfortunate. My doctor and PA were great, but the office staff... is horrible. They never call you back when they say they will, they misinform you, they cause you too much stress wondering what's going on, they don't keep you posted. They never answer the phone. At this point I've left four messages in the last week, and I have sent three messages. Twice from their portal and one direct email. No response. My appointment is on Monday morning at 8:30am, no confirmation on my insurance and what's going on. What the heck is going on, this is ridiculous!I've given up... the stress her office staff has put me through is just not worth it. You can do so much better, please clean house, either change out your office staff, or find a way for them to be more efficient please. You have to do something. This is not how you want to run your practice. It leaves a very bad impression on your more

Had very positive appointments with Jodie and Dr. Sheth for my migraine care. Jodie was so fast with the injections and... has so much valuable info. I started to feel light headed during checkout and the staff was SO helpful—giving me a chair, water, and taking me into a private room until I felt better. Highly recommend this practice for migraine patients, they know what they’re doing!!read more

I was scheduled to be checked and just want to say that the staff was fantastic. They were kind and helpful. I was... asked many questions related to what was going on and not once did I feel as though I was being brushed off. The front desk staff was especially great in assisting me. I'm scheduled to go back for a mri and am glad that I'll be going more

I had such a good experience with Lone Star Neurology, Brent my MRI Tech was so awesome and made sure I was very... comfortable during the appointment. He gave me ear plugs, a pillow, leg support and blanket, easiest MRI ever lol 🤣 My 72 hour EEG nurse Amanda was also so awesome. She made sure I was take care of over the 3 days and took her time with the electrodes to make sure it was comfortable for me! Paige was also a huge help in answering all my questions when it came to my test results, and letting me know her honest opinions about how I should go forth with my more

The professionalism and want to help attitude of this office was present from the moment I contacted them. The follow... up and follow through as well as their willingness to find a way to schedule my dad was above and beyond. We visited two offices in the same day with the same experience. I am appreciative of this—we spend a lot of time with doctors and this was top notch start to more

I love going to this office. The staff is friendly and helpful. The doctor is great. I am getting the best... neurological tests and treatment I have ever had. The only reason I did not give them a 5 star rating is because it is impossible to reach a live person at the office to reschedule appointments. Every time I have tried to get through to the office it says all people are busy and I am sent to a voicemail. If they could get their phone answering fixed, I would give them a strong 5 more

I have had the best experience at this neurologist's office! For over a year I have been receiving iv treatments here... each month and my nurse, Bobbie is beyond wonderful!! She's so attentive, knowledgeable, caring, and detail oriented. She makes an otherwise uncomfortable experience much more pleasant and definitely puts me at ease! She also helps me with my insurance,ordering this specialty medication and dealing with the ordering process which is no easy feat.Needless to say, she goes above a beyond in every way and I'm so grateful to this office and to Bobbie for all they do for me!read more

Let me start by saying that I have been coming here for years. Due to my autoimmune disease, I am in this office... once every three weeks for multiple hours at a time. The office is very clean and the staff very friendly. My only complaint would be there communication via phone. They aren't the best at responding if you leave a voicemail and expect a call back. I understand that this is prob just due to the sheer number of alls they receive daily. What I can say I like the best about the office are the people. Bobby who handles my infusions is great. I never have any issues with her setting up my infusions. She is very quick to reply to messages sent via text and if she were to leave then my whole opinion of the office may change. I also enjoy people like Matt, Lauren, and Jodi. I appreciate all that they do for me and without this team I'm not sure I would be as happy as I am to visit the office as frequently as I have to. Please ensure that these folks are recognized as they are what makes my visit to this office so tolerable :).read more
