Protein For Kids 101

Diet & Nutrition Kids Nutrition Supplements

What is protein?

Along with carbohydrates and fat, protein is one of three macronutrients in our diet (1). It is essential to almost every process in the body, including, growth and repair (1). For children, protein is particularly important for growth, neurodevelopment, and long-team health (2).

Protein consists of 20 amino acids (1); 11 are non-essential amino acids and they can be made by the body, whilst the other 9 are essential amino acids, meaning they must come from food (1). Amino acids form long chains to create the building blocks of protein. They are present in all living cells and provide structure as well as acting as enzymes, carriers, or hormones within the cell (1).

To utilise tissue proteins for energy or glucose production, the body breaks down them into amino acids and (1). Some proteins can act as enzymes to support digestion, the building of bones and glucose production, whilst certain hormones such as insulin and glucagon use proteins to help regulate blood glucose levels and human growth hormone (3).

Why is protein so important for growing kids?

Brain growth and development relies on a high rate of protein synthesis (2). Research has highlighted the importance of protein for infants, with preterm babies who have higher protein intakes displaying greater head circumference growth and improved neurodevelopmental outcomes compared to those with lower levels of protein at birth (2). Furthermore, animal studies have demonstrated the effects of amino acid deficiency, in particular leucine, on decreased neurodevelopment (2).

The amino acids that make up proteins, for example arginine and leucine, are required to synthesise crucial signalling molecules such as neurotransmitters and determine neuronal complexity (2). These amino acids also function to create other compounds, such as creatine, which is a key marker of kidney function, and peptide hormones which exert effects on the endocrine system (2).

How much protein does a child need?

The World Health Organisation and Food and Agriculture Organization states the reference values for protein intake as 0.9g/kg/day for boys aged 3 to 18 years old and girls aged 3 to 15 years old (4). This means if your child weighs 20kg they require 18g of protein per day.

Best sources of protein:

Protein is present in both animal and plant foods. Whilst the amino acids found in animal proteins is closer to that of humans, all of the essential amino acids can be obtained from plant sources as well (1).

Some of the highest sources of protein include:

  • Chicken (32g per 100g)
  • Pork (31g per 100g)
  • Tuna (29g per 100g)
  • Firm Tofu (17g per 100g)
  • Lentils (9g per 100g)
  • Yoghurt (5.7g per 100g)
  • Cheese (Parmesan) (35g per 100g)
  • Pumpkin Seeds (29g per 100g)
  • Eggs (12g per 100g) (5)

How can I increase protein in my child’s diet?

One of the best ways to increase protein in your child’s diet is through snacks either side of meals. Here are some of our top tips to increase protein in your child’s diet:
