1. Fatty Fish
Fatty fish play an important role in brain development thanks to their high levels of omega-3 fatty acids, especially DHA and EPA. These nutrients are crucial for forming the central nervous system and supporting cognitive growth.
Research highlights the benefits of including fatty fish in children’s diets. For instance, studies show that 4-year-olds who received 400 mg of DHA daily for four months improved their listening comprehension and vocabulary skills. Similarly, children aged 8 to 9 who ate 11 ounces of oily fish weekly showed better cognitive abilities, particularly in attention and mental flexibility.
Here’s a quick breakdown of the key nutrients in fatty fish and how they support brain health:
| Nutrient | Brain Benefits | Examples |
|---|---|---|
| DHA/EPA | Improves attention and memory | Salmon, mackerel, sardines |
| Iodine | Supports cognitive function | Ocean fish |
| Vitamin B-12 | Promotes nerve health | Most fish varieties |
To support brain health, aim for about 10.5 ounces (300 grams) of oily fish per week.
If seafood isn’t an option due to allergies or dietary preferences, here are some alternatives:
- Chia seeds: Just 1 ounce provides 5,000 mg of ALA omega-3s.
- Hemp seeds: Three tablespoons contain 2,600 mg of ALA.
- Ground flaxseed: Easy to add to smoothies or baked goods.
- Algal oil supplements: Deliver 400–500 mg of DHA and EPA daily.
Keep in mind, plant-based ALA isn’t as efficiently converted to DHA/EPA, so using a mix of these sources or supplements can help boost omega-3 intake.
Next, let’s dive into some kid-friendly ways to incorporate these brain-supporting foods.
2. Eggs
Eggs deliver 150 mg of choline per serving, which is 25% of the daily value (DV). Choline plays a key role in memory and learning.
Research has shown that eggs can positively impact children’s cognitive abilities. For example, a 2019 study from Ryerson University found that children aged 9–14 who ate egg yolks experienced improved word recall and attention. Their attention scores increased by 1.25 trials.
Here’s a breakdown of the nutrients in eggs and how they benefit brain health:
| Nutrient | Brain Benefit | Amount per Egg |
|---|---|---|
| Choline | Supports memory and learning | 150 mg (25% DV) |
| Selenium | Aids thinking and memory | 20% DV |
| Vitamin D | Promotes brain function | 30% DV |
Most of these nutrients are found in the yolk, which also provides nearly half of the egg’s protein. Nutrition expert Ashlee Carnahan, MS, RDN, from Henry Ford Health, highlights the importance of choline:
“Eggs are one of the best sources of choline, a nutrient that improves cognitive health. This nutrient helps the body make acetylcholine, a brain chemical that’s essential for learning and memory”.
For children 8 and under, serving two whole eggs daily can meet their choline needs and provide other key nutrients. Eggs are highly versatile and make an excellent breakfast option. Swap out sugary cereals for eggs paired with fresh fruit to give your child a nutritious, brain-boosting start to their day.
Research also underscores the importance of eggs during early development. Babies are born with three times as much choline as their mothers, highlighting how critical this nutrient is for brain growth. Emma Derbyshire, founder of Nutritional Insight, explains:
“We’re seeing a lot more ADHD and dyslexia in schools, and some is genetic, but it’s also possible that, in utero, they’re not getting key nutrients. These very subtle neurodevelopment changes are occurring and impacting them later on”.
Up next, we’ll look at another nutrient-packed food to support your child’s brain health.
3. Berries
Berries are a great way to support children’s brain health, thanks to anthocyanins – powerful antioxidants that protect brain cells. These compounds also improve blood flow to the brain and help grow new nerve cells.
Wild blueberries are especially potent, containing 33% more anthocyanins than regular blueberries. In one study, kids aged 8–10 showed better memory performance just two hours after drinking a wild blueberry beverage.
Key Nutrients in Berries
| Nutrient | Brain Benefit | Best Sources |
|---|---|---|
| Anthocyanins | Protect brain cells, boost memory | Wild blueberries (253 mg in 1½ cups) |
| Flavonoids | Improve brain blood flow | Raspberries, blackberries |
| Antioxidants | Reduce inflammation | Strawberries, blueberries |
Studies back up berries’ benefits for cognitive performance. For example, research involving 2,432 teens found a strong connection between eating berries regularly and better academic performance. Another study showed that kids who drank smoothies rich in berries scored higher on memory and attention tests compared to those who didn’t.
“Eating berries on a regular basis along with other fruit and vegetables will ensure that the protective compounds of berries are in your bloodstream, helping to improve your brain function at all ages”.
Easy Ways to Add Berries to Your Child’s Diet
- Toss them into breakfast cereals or oatmeal
- Blend them into smoothies
- Pair them with unsweetened yogurt

Just 1½ cups of fresh blueberries provide 253 mg of anthocyanins, which have been shown to improve verbal memory in children aged 7–10.
4. Leafy Greens
Leafy greens like spinach and kale play a big role in supporting children’s brain development. Packed with nutrients that aid cognitive function and protect growing brains, these vegetables are essential for a healthy diet. Yet, only 10.7% of U.S. children aged 6–11 eat dark green vegetables daily, according to recent studies. This points to a major nutritional gap.
Key Brain-Boosting Nutrients
| Nutrient | Brain Benefit | Serving Reference (Ages 4–8) |
|---|---|---|
| Folate | Helps brain development and function | About 3 cups (100 g) of raw spinach provides nearly 50% of daily needs |
| Lutein | Protects brain cells and boosts cognition | Makes up 59% of infant brain carotenoids |
| Vitamin K | Supports cognitive function | Found in high amounts in kale |
| Beta Carotene | Offers antioxidant protection | Abundant in spinach and collards |
Lutein, in particular, is vital for shielding the central nervous system from oxidative stress. Research also links higher lutein intake during pregnancy to improved verbal intelligence and behavior regulation in children. These findings emphasize the importance of incorporating leafy greens into kids’ diets.
Kid-Friendly Ways to Serve Greens
Getting kids to eat greens often takes patience and creativity. Dr. Jennifer Purifoy from Northwest Family Clinics shares:
“I’ve found that I have to offer the same food on different days up to a dozen or more times until they, at first tolerate it, and then eventually like it and request it.”
Here are some tips to make greens more appealing:
- Blend Into Favorites: Mix spinach into pasta sauce, meatballs, or even pizza.
