In this article, we will explore the best diet for brain health and how it can help support your cognitive health.

Overview of brain health

Brain health is a critical factor in overall wellbeing. Eating healthy, nutrient-rich foods can provide the nutrition needed to support a healthy brain and promote cognitive abilities. This overview of brain health provides an introduction to important dietary components related to brain health, including omega-3 fatty acids, B vitamins, antioxidants, and glucose metabolism.

A well-balanced diet based on whole foods is the best option for optimal brain health. Whole foods include fresh fruits and vegetables as well as whole grains such as oats, quinoa, and brown rice. Eating nuts and seeds high in omega-3 fatty acids is also beneficial for brain health. Additionally, eating foods high in B vitamins such as mushrooms, chickpeas and sunflower seeds can help promote mental function and focus. Foods rich in antioxidants such as dark chocolate, blueberries and spinach can also help reduce oxidative stress on the body which can lead to improved mental clarity and focus. Finally, eating complex carbohydrates that are slowly digested (e.g., sweet potatoes or beans) helps regulate glucose metabolism important for clear thinking processes related to memory recall or decision-making tasks.


Nutrition plays a pivotal role in keeping your brain healthy. Eating a nutritious diet rich in essential vitamins, minerals, and antioxidants can make a big difference in your cognitive health. When it comes to maintaining brain health, there are certain foods that are particularly beneficial.

So, let’s explore the best diet for brain health:


Macronutrients are the three major nutrients that provide energy to the body, making up the bulk of your diet. These include carbohydrates, fats, and proteins. Each macronutrient plays an important role in brain health, and a healthy balance of all three is essential for optimal brain functioning.

Carbohydrates are the primary source of energy for the body and brain, supplying glucose that is needed for mental clarity and alertness. Fats provide important fatty acids that are involved in many aspects of brain functioning; some fatty acids can also help reduce inflammation in the body. Proteins play a key role in maintaining optimal neuron communication throughout the brain and can be found in eggs, fish, nuts, legumes, dairy products, poultry, beef etc.

Eating a balanced diet with plenty of the essential macronutrients will help keep your mind sharp and support healthy cognitive functioning.


Carbohydrates have had a bad reputation in recent times, but this essential nutrient is an important component of a healthy diet. Well-balanced carb consumption can actually help improve brain function and enhance cognitive performance. The recommended amount of carbohydrates per day is 130 grams.

Carbohydrates serve as the primary source of fuel for the brain, brain stem, and central nervous system, giving them energy to perform their functions well. Complex carbohydrates are healthier than simple carbs because they contain more vitamins and minerals that provide additional health benefits. Examples of healthy complex carbs include:

  • Whole grains
  • Oatmeal
  • Quinoa
  • Sweet potatoes
  • Fruits and vegetables

In general whole grains are preferable over refined grains because they are high in fibre and essential nutrients (vitamins and minerals).


Fats are essential nutrients for brain health and function. They are an important source of energy and are required for the absorption of fat-soluble vitamins, including vitamins A, D, E and K. They also help regulate hormones, maintain cell integrity and provide insulation to the body.

Fats come in three main forms: saturated, unsaturated and trans fats. It’s best to stay away from trans fats as they have been linked to an increased risk of heart disease, stroke and other illnesses. Instead focus on incorporating healthy unsaturated fats such as those found in nuts, seeds, avocados, olives and fatty fish like salmon into your diet for brain health – Aim for about 2-3 servings per day.


Proteins are an important part of a healthy diet, especially when it comes to brain health. Proteins provide essential amino acids that your body needs to produce neurotransmitters and maintain brain cell integrity.

Good sources of protein include lean meats, eggs, nuts and seeds, legumes, and plant-based proteins such as tofu and tempeh. Eating enough protein is key for healthy brain aging, as well as for overall health maintenance. It’s also important to remember that lower-sodium proteins are best for your heart health.

Examples of lower-sodium proteins include:

  • Most fish (fresh or canned) without added salt
  • Reduced-sodium deli meat
  • Roasted chicken or turkey without skin
  • Boiled eggs
  • Low-fat plain yogurt
  • Reduced-sodium cheese
  • Vegetable broth made with herbs instead of added salt


Micronutrients are important for optimizing brain health. These essential vitamins and minerals are critical for healthy brain functioning and can help the body to cope with stress, maintain a sense of well-being, and protect against age-related mental decline.

The best way to get an adequate supply of micronutrients is through a balanced diet that includes all food groups in appropriate proportions. Specifically, you should focus on consuming nutrient-rich whole foods including leafy green vegetables, colorful fruits and vegetables, legumes, nuts, seeds and whole grains. Additionally, taking appropriate supplements can be beneficial if you’re unable to get enough micronutrients from diet alone.

Eating a nutritious diet has been shown to improve cognitive functions such as memory, problem solving skills, learning ability and executive functions.


Vitamins are essential nutrients that, when present in the right amounts and combinations, can improve and optimize brain health. The B-vitamins – including B6, B12, and folate – are especially important in this regard as they play a key role in regulating mood, energy levels, and cognitive function. Vitamin C is also important for the synthesis of neurotransmitters (chemicals responsible for sending messages between cells), while vitamin E helps protect neurons from free radical damage. Meanwhile, omega-3 fatty acids are thought to benefit the brain by improving its structure and functioning.

Eating a balanced diet that includes plenty of fruits and vegetables along with healthy fats can help ensure adequate intake of these nutrients. Supplementation may be necessary for some people who don’t get enough vitamins from their diets.


Minerals are essential for proper brain functioning and a healthy diet. Minerals like zinc and iron are required to maintain the electrical signals which enable nerve cell communication, while selenium and magnesium can help protect brain cells from environmental toxins.

Eating foods that are rich in minerals such as fruit, vegetables, whole grains, poultry, seafood and dairy products can provide the brain with much needed nutrients for optimal functioning.

In general, it is best to consume a balanced diet that consists of both macro (carbohydrates, proteins and fats) and micronutrients (vitamins and minerals). This will ensure that your body maintains all the basic requirements for optimal health, including those related to brain health. Consuming sufficient amounts of vitamins B6, B12 and folate can also help maintain cognitive function. Additionally, increasing intake of omega-3 fatty acids has been linked with decreased risk of Alzheimer’s disease by improving blood flow to the brain.


Antioxidants are a group of vitamins, minerals, and other compounds that can help to protect the body from free radicals – molecules that can cause cellular damage. Antioxidants work to reduce inflammation in the body, and thus may improve brain health.

The best sources of antioxidants are fresh fruits and vegetables. Red grapes, blueberries, spinach, broccoli, raspberries, artichoke hearts and oranges are some of the fruits and vegetables that contain high levels of antioxidants. Other plant-based foods such as beans and grains also contain antioxidants. Additionally, antioxidant supplements like vitamins C and E may help to protect against oxidative damage associated with aging or disease.

Eating a well-balanced diet full of fresh fruits and vegetables is always recommended for optimal brain health!

Foods to Include

Eating a nutritious and balanced diet is essential for overall health, and that also applies to brain health. There are certain foods that can help protect the brain from cognitive decline and improve mental wellbeing. Let’s look at some of these essential foods that should be included in a healthy and brain-friendly diet:

Whole grains

Whole grains are an essential component of a brain-healthy diet. Eating whole grain foods can help improve your cognitive function and reduce the risk of neurodegenerative diseases such as Alzheimer’s. Whole grains include oats, barley, quinoa, farro, brown rice, bulgur wheat and other grains that have the “whole” intact.

The best way to ensure you are eating whole grains is to read food labels carefully and opt for foods like oatmeal, quinoa or brown rice instead of processed white bread or white rice. Whole grains are high in fibre which helps slow blood sugar absorption and keep your energy levels stable throughout the day. Additionally, whole grains can also help reduce cholesterol levels in the body and help keep heart health in check.

Fruits & Vegetables

Fruits and vegetables are essential components of a brain-healthy diet. They are rich in antioxidants, vitamins, minerals, fiber, and phytonutrients which protect against inflammation and oxidative damage to the brain. Additionally, they can lower blood pressure which is associated with improved cognitive function. Eating plenty of fruits and vegetables may also help reduce risk of stroke or dementia.

The recommended intake for fruits and vegetables is 2-3 servings per day. Choose from a variety of colors such as red, green, yellow, purple/blue and orange when picking out fresh produce. Examples include: strawberries, apples, broccoli, spinach, tomatoes, carrots and peppers. Also consider frozen or canned options like asparagus or pears if fresh is more expensive or difficult to find in your area.

Healthy fats

Healthy fats are essential in a diet designed to support brain health. Fats help the brain function properly and protect it against damage.

Healthy fats include monounsaturated fats (found in olive oil, avocados, nuts, nut butters and seeds), polyunsaturated omega 3 fatty acids (found in fish and shellfish, chia seeds, hemp seeds and walnuts) as well as saturated fat from whole food sources like grass-fed beef, wild caught salmon and coconut products.

Foods high in healthy fats can also help balance hormones like cortisol which can impact mood and energy levels. Incorporating healthy fats into your diet can also improve your skin health by providing antioxidant protection from free radicals that cause aging of the skin.

Nuts & Seeds

Nuts and seeds are an excellent source of omega-3 fatty acids, vitamins, minerals and fiber, all of which are important for brain health. Omega-3s play a role in reducing inflammation that can damage brain cells, while vitamins and minerals like iron, magnesium and B vitamins help with brain development as well as optimizing how neurons communicate with each other.

Eating more nuts and seeds may also help to reduce the risk of cognitive decline in older people by improving their dietary intake. Nuts and seeds such as almonds, walnuts, pumpkin seeds, sunflower seeds and chia seeds are all high in essential nutrients that benefit the brain. Incorporating a variety of these into your diet may not only provide beneficial nutrients to the brain but may also increase your overall intake of healthy food.


Legumes are one of the most nutrient-dense foods on the planet and include beans, lentils, split peas, and chickpeas. They’re high in protein and low in calories making them an excellent natural food for brain health.

Legumes are also a great source of complex carbs which provide long-term energy to fuel the body’s metabolic processes such as nerve cell production and communication. Legumes are also packed with vitamins, minerals, fiber and antioxidants that benefit both cognition and physical wellbeing.

Incorporating legumes into your diet can help reduce inflammation and oxidative stress caused by poor dietary choices as well as a lack of sleep or exercise; all of which can damage neural pathways leading to cognitive decline. Because legumes are low in calories but very filling they are a great addition to any diet – especially if you’re looking to improve your brain health!


Fish is considered a superfood for brain health, due to its essential fatty acids, high quality protein, healthy fats and minerals. Eating salmon, tuna, mackerel or other types of fish at least two times per week is recommended as part of a healthy diet. These fatty fish contain omega-3 fatty acids which are linked to improved memory and cognition and may protect against age-related mental decline. Research has also shown that omega-3 fatty acids play an important role in reducing inflammation that can cause depression or anxiety.

Other non-fatty fish such as herring, sardines, trout, cod and sea bass are also good sources of protein and essential vitamins. Additionally, rather than frying the fish it is best to bake or grill it in order to preserve its nutrient content.

Foods to Avoid

Maintaining brain health is essential for overall well-being. Diet plays an important role in the health of your brain, so it is important to be aware of the foods that may be detrimental to your brain.

Let’s talk about the foods that should be avoided in order to maintain brain health:

Refined grains

Refined grains are high in sugar, low in nutrients, and can cause a spike in blood sugar levels. Refined grains include white bread, breakfast cereals, cereal bars, and pasta. Although some studies have shown that these foods may provide short-term benefits such as an increase in focus and alertness, they don’t provide the brain with nearly enough nutrients it needs to stay healthy in the long run. On top of that, when blood sugar levels suddenly rise due to eating refined grains they can also cause a crash later on.

To ensure you’re getting adequate nutrition for your brain health try replacing refined grains with whole grain options like oatmeal and quinoa or adding more vegetables to your meals.

Processed foods

Processed foods, also known as ultra-processed foods, are generally defined as products that contain “substantial amounts of” added ingredients such as preservatives, sweeteners, and other artificial flavors. Examples of processed foods include processed meats (e.g., hot dogs), chips, crackers, candy, sugary drinks and desserts.

These types of processed food can be detrimental to your brain health. They’re often high in fat and sugar–two factors that can increase inflammation in the body and negatively affect cognition. Additionally, many processed foods are low in essential nutrients like vitamins and minerals that are important for brain functioning. Studies have shown that diets high in ultra-processed foods were associated with poorer cognitive performance compared to diets lower in these types of food. So it’s best to limit or avoid these types of processed food when possible!

Sugary beverages

Sugary beverages, such as sodas, juices, and sports drinks, can be detrimental to brain health. These beverages offer no nutritional benefit and result in a “sugar crash” that can interfere with cognitive processes like learning and problem-solving.

The sugar in these drinks also leads to an increased risk for developing Type 2 diabetes and other metabolic issues which can contribute to long-term declines in cognition. High glycemic foods such as white breads, cereals, candies, sweetened yogurts or any processed sugars should be minimized if you want to maintain optimal brain health.

Replacing sugary beverages with water is a great way to ensure that your brain is getting the fluids it needs while avoiding the extra sugar and empty calories. Water also helps transport oxygen and other important nutrients throughout the body which supports optimal brain functioning.

Trans fats

Trans fats, also known as trans fatty acids, are a form of artificially produced fat found in many processed foods. These fatty acids are created when hydrogen is added to liquid vegetable oils to make them more solid and have a longer shelf life.

Trans fats have been shown to increase an individual’s risk for stroke by 23% and are linked to other serious medical conditions such as heart disease, diabetes, and obesity. They also do not provide any beneficial nutrition and instead lead to an increased calorie intake without providing the body with any of the necessary trace minerals or vitamins normally found in healthy fats such as omega-3 fatty acids.

Trans fats should be avoided completely from one’s diet for optimal brain health.


After analysing the evidence, we can conclude that a Mediterranean diet is likely the best dietary approach for promoting optimal brain health. This diet is rich in plant-based foods, fish, seafood, nuts, olive oil and other healthy fats, and is low in processed foods, red meat and added sugars.

By following this type of diet, you get the essential nutrients needed for proper brain functioning and can reduce your risk of developing neurological problems in the future.

Summary of the best diet for brain health

The best diet for brain health is one that is balanced, with a variety of different foods. A typical meal plan should include:

  • Lean protein sources such as fish, chicken, or beans;
  • Healthy fats like olive oil, nuts, and avocado;
