Protein is an essential building block for the healthy growth of your preschooler. From building up and maintaining muscles to developing the immune system, protein is involved at every step of the way. As children develop eating habits and discover new foods, ensuring protein foods are part of the mix supports proper development.
Read on to learn more about protein and see how simple it is to incorporate it into your child’s diet. We’ll provide kid-friendly meal ideas and creative snacks to keep everyone happy and healthy.

Protein is one of the three big nutrients required by the body along with carbohydrates and fat. When eaten, protein provides calories (energy) and amino acids (building blocks) to create and maintain all systems in the body.
Protein can be described as a long string of beads, where each bead is called an amino acid. There are 20 unique amino acids that exist and all of them are important for the body. Of the 20, 9 of them are considered “essential”, meaning that they can only be obtained by eating protein foods. In contrast, the other 11 are found in foods and can also be made by the body itself!
We often say “children grow up so quick”. Physically, that rapid growth is especially true in those early years of development. That’s because every part of the body is made up of protein building blocks, including muscles, hair, and skin. On top of building these tissues, protein helps maintain them and repair them as children age and develop.
Another important role for protein is to build up the body’s defenses, also known as the immune system. This helps the body fight off infections and promotes healing from injuries.
1-3 years
At the toddler stage, 13 grams of protein per day is the minimum amount necessary for proper growth. This amount can be met through a few simple foods each day such as egg, milk, beans, or meat. In fact, you’ll likely notice that the amount of protein can add up quickly. Rest assured that receiving more than 13g is okay too!
4-8 years
As children get bigger, their protein requirements increase to a minimum of 19 grams per day to support their growth. Similar to toddlers, serving a variety of proteins will help meet their needs, and going over is not an issue.

Proteins are found in a wide assortment of animal and plant foods, offering choices for even the pickiest of eaters. Animal sources of protein include dairy products, eggs, fish, meat, and poultry. Similarly, good plant sources of protein include legumes, nuts, seeds, tofu, and whole grains.
For selective eaters, focus on providing protein foods that they enjoy first and foremost. Widening their food acceptance will come with time, so take advantage of the protein items they do enjoy. Further, use repeat exposures and be sure to introduce new items with patience.
The best way to ensure your child gets enough protein is to offer a selection throughout the day. Their protein needs aren’t too high at this stage, so offering a little with each meal and snack will do. Be creative and don’t overthink it!
Try to focus on what can be added, rather than changing your kid’s favourite dishes. This could look like sprinkling seeds onto oatmeal, mashing lentils into pasta sauce, or tossing walnuts into banana bread batter.
Swapping ingredients can make for an easy protein boost too. Milk can be used instead of water in a variety of sweet and savoury dishes including pancake batter and soups. Another idea is serving high protein Greek yogurt instead of regular yogurt or whole grain pasta instead of white pasta.
Eggs are another versatile protein and should not be limited to breakfast only. Think scrambled egg wraps for lunch, muffins or hard boiled eggs for snack, and egg fried rice for dinner.
The list of possibilities goes on and can be adapted to suit your family’s culture, preferences, and budget.

While this is not an extensive list, these foods have a significant amount of protein per serving. On the other hand, some fruits, vegetables, and grains also contain protein to a lesser extent. Alone, these items can’t meet protein needs but should be eaten to provide variety and other important nutrients.
To get a sense of how much protein is found in various foods, check out the table below:
| Food | Serving Size | Protein (g) |
| Chicken | ½ cup, cooked | 22 |
| Salmon | ½ cup, cooked | 20 |
| Plain Greek Yogurt | ½ cup (116 g) | 12 |
| Tofu | ½ cup | 10 |
| Lentils | ½ cup, cooked | 9.5 |
| Edamame | ½ cup, cooked | 9 |
| Dairy, Soy, or Pea Milk | 1 cup | 8 |
| Chickpeas | ½ cup, cooked | 7 |
| Peanut Butter | 2 tbsp | 7 |
| Eggs | 1 large | 6 |
| Mozzarella Cheese | 1 inch cube | 6 |
| Green Peas | ½ cup, cooked | 4.5 |
| Quinoa | ½ cup, cooked | 4.3 |
| Pasta | ½ cup, cooked | 4.3 |
| Plain Yogurt | ½ cup | 4 |
| Whole Wheat Bread | 1 slice | 4 |
| Hummus | 2 tbsp | 2.5 |
| Sweet Potato | ½ cup, cooked | 2.3 |
| Avocado | ½ fruit | 2 |
Have you been considering using protein powder to ensure your preschooler gets enough protein? As mentioned above, the protein requirements for toddlers and children are not as high as you may have initially thought. The need for a protein supplement may therefore not necessarily be called for and could in fact be harmful.
The body can only effectively use a certain amount of protein per day. While this amount varies by age and weight, it is usually not exceeded through food intake. However, introducing additional protein powder could result in excess strain on the body’s systems and unintentional weight gain.
Further, protein powder is an isolated form of protein coming from milk, eggs, or plant sources. It is often used by adults to aid in muscle growth and repair. On the other hand, whole protein foods additionally offer a wide variety of other essential nutrients necessary for healthy growth.
Whether your child could benefit from protein supplements will depend on their age, physical activity level, and their overall health.
Potential reasons for introducing protein supplements
If you are unsure if your child could benefit from a protein supplement, consult your dietitian or pediatrician for guidance.

Yes, eggs are chock full of nutrients and support brain, heart, and bone health. They are an easy source of protein for kids and can be offered daily as part of a healthy, balanced diet. Be sure to offer eggs in a variety of ways to avoid taste fatigue.
While meat has a significant amount of protein per serving, there are many other excellent protein-rich options to choose from. 2% milk, eggs, legumes, tofu, and nuts/seeds are all versatile, nutrient-rich options to include in your child’s diet.
In the short term, your child may feel more hungry and fatigued if they aren’t eating enough protein. On the other hand, if protein needs aren’t met in the long term, this could lead to several health issues. These include troubles concentrating, getting sick more often, longer wound healing time, bone and joint pain, and even slowed growth.
Definitely! Playing, learning, and growing all use a significant amount of energy that require constant refueling. Protein provides energy and supports growth and repair, making it an essential part of a balanced diet. Further, protein foods also contain other essential nutrients to support your child’s daily activities and development.
A protein food that contains all 9 essential amino acids is considered complete. This is because these amino acids cannot be produced by the body and must be obtained through food. Some examples include meat, poultry, fish, dairy, eggs, soybean products like tofu and edamame, quinoa, hempseed, and nutritional yeast.
