Essential Vitamins And Minerals For Your Child’s Growth: Nutritious Food Sources To Fuel Development

To help you strengthen your immune system and maintain a healthy diet, we’ve put together an exhaustive list of foods that are rich in essential vitamins and minerals. Whether you're looking to boost your immunity or improve overall health, here's everything you need to know. Here we go:

VITAMINS

Vitamins are essential micronutrients required by the body to support a range of vital functions. They are divided into two groups, fat-soluble vitamins (A, D, E, K) and water-soluble vitamins (B-complex and C).

FAT-SOLUBLE VITAMINS

VITAMIN A

Vitamin A is a fat-soluble vitamin that is required for good vision, improved immunity, healthy skin, and several other aspects of growth and development. Vitamin A deficiency is the leading preventable cause of blindness among children. Even a mild deficiency of Vitamin A can increase the risk of respiratory disease or diarrhea in children.

Food sources of Vitamin A 

Orange-coloured or yellow-coloured fruits and vegetables like carrot, pumpkin, sweet potato, mango, papaya, and apricot; dairy products, eggs, and spinach.

VITAMIN D

Vitamin D is also known as the sunshine vitamin. It works with minerals like calcium and phosphorus to keep bones and teeth strong. In children, a deficiency of Vitamin D can cause rickets, which is the failure of the bone to mineralize, thus increasing the risk of fractures.

Food sources of Vitamin D 

Oily fish (herring, salmon, tuna and sardines), fish liver oil, egg yolk, and fortified dairy products. However, our bodies make enough Vitamin D when our skin is exposed to sufficient sunlight in the right manner.

VITAMIN E

Vitamin E acts as a powerful antioxidant and helps protect the cells against wear and tear. This vitamin also boosts the immune system and helps in the development of healthy skin and eyes. Vitamin E deficiency can result in nerve and muscle damage, vision problems, and weakened immunity.

Food sources of Vitamin E 

Vegetable oil like sunflower and canola oil, eggs, nuts like peanuts and almonds, peanut butter, pumpkin, asparagus, spinach, avocado, whole grains, and fortified cereals.

VITAMIN K

Vitamin K is essential for blood clotting. It is produced by certain bacteria in our gut. Newborn babies have very low levels of Vitamin K. Breastfed babies also have low levels of Vitamin K because breastmilk has very low levels of this essential nutrient. Low levels of Vitamin K can increase the chance of severe bleeding. Even small cuts can continue to bleed if the Vitamin K in the body is not enough. So, newborns are given Vitamin K injections to prevent them from bleeding.

Food sources of Vitamin K

Green leafy vegetables like spinach and kale, broccoli, cabbage, turnip greens, soybean oil, and fermented soy products.

WATER-SOLUBLE VITAMINS

We now turn our focus to water-soluble vitamins. These are the B-complex vitamins, which are found in many foods. There are eight types of B vitamins. Except for Vitamin B12 and B9, other B-complex vitamins are not stored in the body and must be replaced every day. One word of caution is that since these vitamins are water-soluble, they can be easily destroyed in the cooking process. So, you need to be watchful. We now look at these vitamins in greater detail.

VITAMIN B1 (THIAMINE)

Vitamin B1 plays a crucial role in energy metabolism and is therefore important for the growth, development, and function of cells. Thiamine also plays a role in nerve function. Thiamine deficiency can cause irritability, confusion, poor arm or leg coordination, lethargy, fatigue, and muscle weakness.

Food sources of Vitamin B1

Wheatgerm, wheat bran, nuts, seeds, yeast extract, whole grains, legumes, meat, fish, and other fortified foods.

VITAMIN B2 (RIBOFLAVIN)

Vitamin B2 plays a major role in energy production, cellular function, and metabolism of fats and drugs. Research has shown that riboflavin can have a beneficial effect on migraines in children. Riboflavin deficiency causes ariboflavinosis. Symptoms include an inflamed tongue with cracks and redness, anxiety, sensitivity to light, hair loss, skin rash, and reddening of the cornea.

Food sources of Vitamin B2

Organ meats, lean meats, egg, milk, legumes (beans and peas), quinoa, nuts and seeds.

VITAMIN B3 (NIACIN)

Niacin plays an important role in converting carbohydrates and fat into energy. It also helps support the nervous and digestive systems' functions. Niacin deficiency causes pellagra. Symptoms include loss of appetite, mental confusion, swollen tongue, weakness, and dizziness. A mild deficiency of niacin also slows down the body's metabolism.

Food sources of Vitamin B3

Meat, fish (tuna, salmon), milk, broccoli, tomato, carrot, dates, mushroom, whole grains, and nuts.

VITAMIN B5 (PANTOTHENIC ACID)

Vitamin B5 is needed to metabolize macronutrients like carbohydrates, proteins, and fats as well as to produce red blood cells and steroid hormones. It also supports the proper functioning of the nervous system and the liver. Deficiency of Vitamin B5 is rare and the symptoms include headache, fatigue, impaired muscle coordination, and gastrointestinal problems.

Food sources of Vitamin B5

Cabbage, broccoli, sweet potato, mushroom, dairy products, eggs, peanuts, and legumes.

VITAMIN B6 (PYRIDOXINE)

Vitamin B6 plays an important role in brain development in children. It is also involved in the production of hemoglobin and helps boost immunity. Deficiency of Vitamin B6 results in a weakened immune system, a swollen tongue, and anemia.

Food sources of Vitamin B6 

Green leafy vegetables, chickpeas, fish and shellfish, whole grains, bananas, and potato.

VITAMIN B7 (BIOTIN)

Biotin is a vital nutrient that promotes healthy hair, skin, and nails. A deficiency of Vitamin B7 can result in pale skin, a cracked tongue, dry skin, rashes around the eyes, nose, and mouth, hair loss, weakness and fatigue.

Food sources of Vitamin B7

Egg yolk, chicken, salmon, cauliflower, sweet potato, nuts and seeds.

VITAMIN B9 (FOLATE)

Folate helps in the development of the fetal nervous system and the formation of red blood cells. It also reduces the risk of birth defects such as spina bifida. Folate deficiency can cause weight loss, tiredness, fatigue, weakness, and megaloblastic anemia (folate-deficiency anemia).

Food sources of Vitamin B9 

Green leafy vegetables, corn, legumes, seeds, liver, chicken, egg, and citrus fruits.

VITAMIN B12 (CYANOCOBALAMIN)

Vitamin B12 helps in the formation of red blood cells. It produces and maintains the myelin, the insulating layer around nerves. Vitamin B12 deficiency can cause developmental delays in children, irritability, weakness, shortness of breath, loss of vision, appetite, and weight.

Food sources of Vitamin B12

Vitamin B12 is naturally present only in animal products such as liver, meat, milk, cheese, and eggs.

VITAMIN C (ASCORBIC ACID)

Vitamin C has several vital roles to play and these include boosting immunity and enhancing the absorption of iron. Vitamin C deficiency causes scurvy. Symptoms include bleeding gums, bruising, sore arms and legs, fatigue, and changes in hair and skin.

Food sources of Vitamin C

Citrus fruits, red and green capsicum, broccoli, strawberry, cantaloupe, tomato, and brussels sprouts.

MINERALS

From vitamins, we now move to the other important constituent of growth minerals. These are micronutrients that the body needs to develop and function normally. Here, we look at some major minerals.

CALCIUM

Calcium is essential for healthy bones and teeth and plays a vital role in the overall growth and development of children. Calcium also plays a key role in nerve and muscle function, including blood clotting and heart contractions. Inadequate calcium in the body can result in weak, fragile, and porous bones.

Food sources of calcium 

Milk and milk products like cheese and yogurt (children with lactose intolerance can opt for soy and nut milk); broccoli, fish (sardines), and fortified cereals.

IRON

Iron plays a vital role in the production of red blood cells, which carry oxygen around the body. Iron also plays a key role in energy production. Iron deficiency causes anemia and is the most common nutritional deficiency, especially among children and teenage girls. Common symptoms include fatigue, pale skin, shortness of breath, dizziness, and damaged hair and skin.

Food sources of iron

Lean meat, poultry, seafood, eggs, dark green leafy vegetables (spinach, kale), whole grains, legumes, and dried fruits.

ZINC

Zinc plays an important role in growth, immune function, and neurological function. It also aids in wound healing and helps in the formation of strong bones. Zinc deficiency in children can lead to delayed physical growth, impaired immunity, and delayed mental development.

Food sources of zinc 

Meat, chicken, seafood, milk, whole grains, legumes, and nuts.

IODINE

Iodine is an essential nutrient that helps produce thyroid hormones, which help regulate growth, development, and metabolism. Iodine deficiency can cause hypothyroidism. An underactive thyroid can result in fatigue, weight gain, hair loss, and constipation.

Food sources of iodine

Seafood, seaweed, iodized salt, bread, dairy products (milk, cheese, yogurt).

MAGNESIUM

Magnesium plays a vital role in nerve function and the building of bones and healthy muscles. It also helps in the release of energy from food. Symptoms of magnesium deficiency include nausea, fatigue, seizures, cramps, abnormal heartbeat, numbness and tingling.

Food sources of magnesium

Milk, whole grains, green leafy vegetables, legumes, lean meat, fish, nuts, seeds, and banana.

PHOSPHORUS

Phosphorus works with calcium in the formation of strong bones and teeth. It also helps the body to store and use energy, and helps with kidney function, and muscle contraction. Phosphorus deficiency can cause bone diseases such as rickets in children.

Food sources of phosphorus

Protein-rich foods such as milk, meat, cheese, and eggs; wheat germ, whole grain bread, nuts, and seeds.

POTASSIUM

Potassium is an essential mineral that helps maintain the body's fluid volume while constantly balancing electrolytes in the body. It also helps in cell function, transmission of nerve impulses, metabolism of carbohydrates and proteins, and preservation of bone mineral density. Potassium deficiency is called hypokalaemia and symptoms of the condition include muscle weakness, constipation, fatigue, and breathing difficulty.

Food sources of potassium 

Banana, grapefruit, tomato, chicken, nuts, seeds, raisins, prunes, legumes, spinach and broccoli.

The human body cannot naturally produce the required vitamins and minerals. It is, therefore, important to ensure that your child gets these vital nutrients in the food they consume. At the end of the day, a well-balanced diet is all it takes to prevent deficiencies.
