Brain-Boosting Foods and Nutrients For Cognitive Health

The components and inclusions of cognitive health are often talked about, but the term itself isn’t that popular. While physical and mental health are common terminology, cognitive health is often not focused on as such—however, we talk about it all the time. When it comes to memory, focus, mental clarity, and sharpness, that’s all cognitive health!

Just as your body and mind benefit from a healthy diet, your cognitive health, aka brain, requires certain nutrients and foods to thrive as well. Genetics and lifestyle are significant contributors to brain health, but mental agility is impacted by cognitive health. There are many foods that you actually may already have as part of your staple diet that help with brain health. They are not hard to find, nor are they hard to prepare, and simple intentional steps towards your diet could do wonders for your cognitive health.

The Link Between Nutrition and Cognitive Health

Undoubtedly, the brain is a complex organ; even though it’s constantly at work, we don’t think about what it needs to function well. Neurons, cells that the brain uses for communication, are dependent on energy, vitamins, and minerals—this helps them transmit the signals they need effectively. If there is an imbalance or any deficiency in the essential nutrients it needs, there can be a negative impact on cognitive function. 

So, in simple terms, a nutrition-rich diet can definitely help improve and maintain memory, attention, and problem-solving skills. Diets that have high amounts of healthy fats, vitamins, minerals, and antioxidants are suggested by researchers to be the best for brain health. Commonly, diets like the Mediterranean or DASH are heavily effective due to the abundance of whole grains, fresh greens, nuts, and healthy oils—most of which are also staples in many Indian cuisines.

Brain-Boosting Foods and Nutrients to Include in Your Diet

1. Turmeric (Haldi)
   This spice that is commonly found in most kitchens and has been a devoted part of Indian diets has a compound called curcumin. This is where turmeric gets its anti-inflammatory and antioxidant properties from. Research also shows that curcumin can cross the blood-brain barrier, allowing it to reduce brain inflammation and help with new brain cell growth.
   • How does it help?
     Curcumin present in turmeric helps with a process called neurogenesis (creating new neurons in the brain) and reducing oxidative stress (responsible for conditions like Alzheimer’s)—it helps with memory and learning capabilities.
   • How much and when:
     1-2 grams, or half a teaspoon, a day of turmeric is what is ideal—in fact, pairing it with black pepper is said to help with absorption. In Indian culture, turmeric is best consumed in haldi doodh or golden milk before bedtime or in meals.
2. Seeds
   Seeds like almonds, walnuts, sunflower, and flax seeds are a great source of vitamin E, omega-3 fatty acids, and antioxidants. All of these protect brain cells from oxidative stress.
   • How does it help?
     Vitamin E helps reduce cognitive decline, and omega-3s help in improving memory and brain connectivity.
   • How much and when:
     Around 28 grams of mixed nuts make a great mid-morning or early evening snack.
3. Fatty fish
   Fish that are high in omega-3 fatty acids are great for maintaining brain structure and function—these would include sardines, mackerel, and salmon. Besides helping in memory, they also reduce the risk of cognitive decline.
   • How does it help?
     DHA, an omega-3 fatty acid, helps build the cell membranes in the brain and reduce inflammation.
   • How much and when:
     2 servings of fatty fish a week is ideal—such as grilled fish for lunch or fish curry for dinner.
4. Vegetables
   Although staple in most diets, certain vegetables are a great source of B6, B12, and folate, which help prevent cognitive decline. Vegetables like spinach, fenugreek (methi), and amaranth (chaulai) leaves are just some of them. Vegetables also provide antioxidants that protect the brain from free radical (contribute to brain aging) damage.
   • How does it help?
     The B vitamins help in neurotransmitter production and can help reduce brain fog.
   • How much and when:
     About a cup of vegetables a day can be included in lunch and dinner meals like palak paneer, methi paratha, or dals.
5. Berries
   Blueberries, strawberries, and Indian gooseberries (amla) are filled with antioxidants and flavonoids that are known to improve memory and cognitive performance. They also encourage brain cell communication, improving overall brain function.
   • How does it help?
     Flavonoids boost neuronal signaling and help in the delaying of cognitive aging.
   • How much and when:
     About 100 grams a day as part of a mid-morning snack or in delicious smoothies.
6. Whole grains
   Whole grains like brown rice, oats, and millets (ragi and jowar, for example) have glucose, which is the primary fuel source for brain cells. They are also rich in vitamin E, and yes, you guessed it, the B vitamins—optimal for brain health.
   • How does it help?
     Glucose is the source of energy for brain activity, and vitamins improve focus and memory.
   • How much and when?
     Try to eat whole grains at least two meals a day—like oats porridge at breakfast or brown rice pulao for lunch.
7. Legumes
   Magnesium, iron, and folate all play a role in brain cell communication and energy production. They are also rich in fiber and help in keeping blood sugar levels stable. Some of the best legumes to include in your diet are chickpeas, lentils, and black beans.
   • How does it help?
     Magnesium helps neurotransmitter regulation, and folate improves brain metabolism.
   • How much and when?
     How much and when: About one cup of legumes in your daily meals is ideal—this could be in dals, hummus, or salads.
8. Dark chocolate
   Dark chocolate—particularly ones made of at least 70% cocoa—has flavonoids, caffeine, and antioxidants impacting both memory and mood positively. Moderate amounts of dark chocolate can also help in brain blood flow.
   • How does it help?
     Flavonoids help with the formation of new neural connections.
   • How much and when?
     About 10-15 grams daily as an after-meal treat is a great way to include this sweet (a bit bitter actually) into your diet.
9. Eggs
   Eggs, a stable breakfast, have choline, which is a nutrient essential for memory and brain development. It also has vitamins D and B!
   • How does it help?
     Choline helps in the production of acetylcholine, a neurotransmitter linked to memory.
   • How much and when?
     One egg a day—during breakfast or lunch, whichever you’d prefer.
10. Green tea
    Green tea has catechins and L-theanine, which are compounds that improve brain function, reduce stress, and help with better focus.
    • How does it help?
      L-theanine helps with relaxation without the drowsiness and helps improve focus.
    • How much and when?
      One to two cups a day is ideal during mid-morning or early afternoon.
