A child’s brain constantly absorbs information and skills like a sponge. From before birth, their brains are busy growing and learning. As infants, their brains expand, especially as they learn basic motor skills like crawling and walking.
During the toddler years, their brains rapidly develop cognitive abilities such as problem-solving and language skills. Without the right nutrients, this crucial development could be stunted, affecting memory, attention, and learning in the future.
So, providing proper nutrition during these early years is essential for supporting their brain growth and development.
During the first 3 years of a child’s life, nutrition is crucial in shaping their future health, well-being, and ability to thrive. From conception until their third birthday, their nutrients through breast milk, baby formula, and solid foods profoundly impact their developing brain.
These foods aren’t just about filling their tummies; they provide the essential nutrients their growing brains need to reach their full potential. These early dietary choices can have long-lasting effects on a child’s cognitive development and overall health.
The brains of normal children develop in a complex process involving changes in the number and organisation of brain cells in a specified sequence. The most active period of neurologic development occurs in the first 1,000 days of life. This period, beginning at conception and ending at the start of the third postnatal year, is a time of tremendous opportunity for neuro-development and great vulnerability.
All nutrients are crucial for brain growth and function. According to AAP, the following are specific nutrients that are essential during early development.
Protein: Essential for building and repairing brain tissue, They play a vital role in supporting brain growth, ensuring the proper size of brain structures, and contributing to the formation of essential neural connections.
Foods rich in protein include
Omega-3 fatty acids: Long-chain polyunsaturated fatty acids, such as omega-3 fatty acids support the structure and function of brain cell membranes, promote nerve cell growth and communication, and have been associated with improved cognitive function.
Foods rich in Omega-3 fatty acids include
Choline: Choline is crucial for early brain development. A 2020 review of 54 studies found that adding choline to a child’s diet in the first 1,000 days of life could protect against nerve cell damage, improve cognitive function, and support overall brain development.
Foods rich in choline include
Iron: Necessary for oxygen transport in the blood, including to the brain, and for the production of neurotransmitters. Iron deficiency has also been associated with attention deficit hyperactivity disorder study says.
To guarantee your child’s iron intake, prepare shellfish and red meat, rich sources of iron. Additionally, consider incorporating legumes, pumpkin seeds, and spinach into their diet, as these foods also provide iron.
Folate: According to research, children with sufficient folate intake demonstrated better cognitive scores compared to those with insufficient folate intake. You’ll find folate in leafy greens and fortified foods like breads and cereals.
Zinc: Zinc plays multiple roles in the human body. Besides boosting the immune system, it aids in protein and DNA production, assists in wound healing, supports childhood growth, and acts as an antioxidant.
Zinc occurs naturally in many foods, such as beans, meat, and fish. It is also available as a dietary supplement.
Vitamin A: Vitamin A plays an important role in vision and bone growth and helps protect your child’s body from infections. It can be found in liver, fish, dairy products, and colourful fruits and vegetables like carrots, sweet potatoes, and spinach.
Vitamin D: Vitamin D promotes healthy bones by regulating calcium levels. It also contributes to the normal functioning of the immune system, keeping your child healthy and alert. Sources of vitamin D include fatty fish like salmon and tuna, egg yolks, fortified dairy and plant-based milk products, and exposure to sunlight.
Vitamin B6 and B12: Vitamin B6 is crucial for processing proteins, fats, and carbohydrates, as well as forming red blood cells and neurotransmitters.
Meanwhile, Vitamin B12 is vital in brain development, neural myelination, and cognitive function. Insufficient vitamin B12 during early childhood can lead to negative health effects, such as impaired cognitive development.
Iodine is necessary to produce thyroid hormones, which play a crucial role in brain development, particularly during pregnancy and early childhood. Iodine deficiency can lead to cognitive impairment and developmental delays.
While no single food can guarantee perfect brain development in toddlers, certain foods are rich in a variety of essential nutrients. However, it’s important to introduce new foods cautiously to avoid any potential allergies.
Eggs are nutritious and a favourite among young children. Packed with brain-boosting nutrients like choline, vitamin B12, and protein, they support normal brain development and cognitive function. Just two whole eggs a day can provide choline intake for children 8 and younger.
In 2017, a study indicated that Americans consume choline from eggs. A large egg yolk contains 125 milligrams (mg) of choline, meeting half the requirement for children aged 4–8.
You can easily incorporate leafy greens like spinach and kale into your child’s meals by adding them to dishes like soups, stir-fries, or pasta sauces. These greens are rich in iron and folate, which are important for your child’s growth and development. Plus, they add extra nutrients and flavour to their meals!
Research suggests that children who consume adequate folate exhibit better cognitive abilities than those with insufficient intake.
Nuts, seeds, and nut butter are fantastic snacks packed with protein and zinc, crucial for your child’s brain growth and memory development.
However, whole nuts and seeds can pose a choking risk, so opt for small amounts of peanut butter mixed with water or peanut-flavoured puff snacks instead. Just ensure the puffs are made from real peanuts without any artificial additives.
Beans provide essential nutrients like zinc, protein, iron, folate, and choline, which are beneficial for brain development. Certain varieties like kidney, pinto, and soybeans also offer high omega-3 fatty acids.
Additionally, adding lentils to soups, dahls, and curries is a tasty and nutritious way to incorporate them into meals. The soft texture of red lentils makes them particularly suitable for younger children, as they’re easier to chew and digest.
Studies indicate that the microbiome is crucial for brain development. Probiotics in fermented foods like Greek yoghurt can help maintain a healthy microbiome.
Unsweetened yoghurt is a simple and kid-friendly option for promoting brain growth. It contains essential nutrients like protein, zinc, choline, and iodine.
Iodine is particularly crucial for children as it supports the production of thyroid hormones, which are essential for brain development and neurological processes.
They are excellent for promoting brain development as they contain protein, zinc, iron, choline, iodine, and omega-3 fats.
However, avoiding high-mercury seafood like tuna and swordfish is important, as excessive mercury can harm a child’s developing nervous system. Instead, choose low-mercury options such as shrimp, salmon, tilapia, crab, or cod.
Whole grains support babies’ concentration by providing a steady energy source to their brains. With a low glycemic index, they release glucose into the bloodstream slowly, helping keep your child alert throughout the day.
Additionally, whole grains are rich in folate, vital for optimal brain function.
Scientific evidence shows that strawberries, blackberries, blueberries, and other berries are incredibly beneficial for the brain. They’re rich in antioxidants that combat the damaging effects of free radicals.
Berries’ vitamin C content boosts children’s learning and memory and prevents oxidative stress in the brain.
