According to the American Academy of Pediatrics, sufficient protein intake is critical to support the typical growth and development of children. A diverse and balanced diet from whole food sources is key when considering what type of protein is best for kids, as their needs change with age and activity level.

Quick Summary

This guide examines the best protein options for children, from whole food sources like dairy, eggs, and legumes to supplementary choices. It covers daily protein requirements by age and highlights the nutritional benefits of both animal and plant-based proteins to support healthy growth.

Key Points

Variety is Key: The best approach is to offer a variety of high-quality protein sources, both animal and plant-based, throughout the day to ensure a complete nutritional profile.
Whole Foods First: For most children, whole food sources like eggs, dairy, lean meat, and legumes provide all the protein they need without the need for supplements.
Daily Requirements Vary by Age: Protein needs are highest per pound of body weight during childhood, with specific daily recommendations increasing with age.
Use Supplements Wisely: Protein powders should only be given to children under the guidance of a healthcare professional, especially for specific needs like growth concerns or intense athletic training.
Beware of Excess Protein: Excessive protein intake can strain a child's kidneys and lead to weight gain, making a balanced diet the safest and most effective strategy.
Watch for Additives in Powders: If supplements are used, choose those specifically formulated for kids and avoid artificial sweeteners, excessive sugar, and heavy metals by checking for third-party certifications.

Understanding Your Child's Protein Needs

Protein is the building block for all cells in the body, essential for muscle and tissue growth, and crucial for a healthy immune system. Pediatric protein needs are higher per pound of body weight than adults to fuel this rapid development. Fortunately, for most children, meeting these requirements is straightforward through a balanced diet of whole foods, without the need for supplements.

Daily Protein Guidelines by Age

Daily protein needs vary significantly by age and, for adolescents, by gender. The following are general recommended dietary allowances (RDAs):

Ages 1–3: Approximately 13 grams per day.
Ages 4–8: Approximately 19 grams per day.
Ages 9–13: Approximately 34 grams per day.
Ages 14–18 (Girls): Approximately 46 grams per day.
Ages 14–18 (Boys): Approximately 52 grams per day.

These can be easily met with a variety of foods throughout the day, such as an egg for breakfast (6g), a small portion of meat at dinner (around 20g), and a glass of milk (8g).

High-Quality Animal-Based Protein Sources

Animal-based proteins are considered “complete” because they contain all nine essential amino acids. They are also typically highly bioavailable, meaning the body can easily absorb and use the protein.

Best animal protein options for kids include:

Eggs: A versatile and complete protein source. Hard-boiled eggs make a great on-the-go snack, while scrambled eggs are a breakfast favorite.
Dairy Products: Greek yogurt is packed with protein (12-14g per 5-6oz), and cheese sticks or cubes are a simple snack rich in protein and calcium. Milk is also a solid source of protein.
Lean Meats and Poultry: Chicken and turkey, when baked or grilled, offer high-quality protein. It is best to choose lean cuts and remove the skin.
Fish: Oily fish like salmon are rich in protein and omega-3 fatty acids, which support brain development. Consider milder-tasting fish like cod or tilapia for picky eaters.

Excellent Plant-Based Protein Sources

For families with dietary restrictions or those simply aiming for more variety, plant-based proteins are a fantastic option. Many plant sources are not complete proteins on their own, but a varied diet can ensure all essential amino acids are consumed.

Top plant protein options for kids include:

Beans and Legumes: These are fiber-rich powerhouses. Chickpeas are the base for hummus, a perfect dip for veggies, while lentils and black beans can be added to soups, rice, and wraps.
Soy Products: Tofu and edamame are excellent plant-based protein sources. Tofu can be scrambled or baked, and edamame offers a fun snack experience.
Nuts and Seeds: Nut butters are a kid-friendly staple, great on toast or with fruit slices. For older children, nuts and seeds can be added to oatmeal or trail mix. Remember that whole nuts and seeds are choking hazards for children under five.
Whole Grains: Quinoa is a complete protein and can be a base for salads or served with veggies. Oats also provide a good source of protein and fiber.

Comparison: Animal vs. Plant Protein for Kids

To help parents decide, here is a quick comparison of the two protein source categories.


Feature	Animal Protein	Plant Protein
Completeness	Naturally contains all essential amino acids.	May be incomplete alone; variety in the diet ensures all amino acids. Blends like pea and rice protein can create complete profiles.
Bioavailability	High; easily digested and absorbed by the body.	Generally lower than animal protein due to antinutrients, though still very effective.
Nutrient Density	Rich in iron, zinc, and B vitamins (especially B12).	Often higher in fiber and protective phytochemicals.
Allergies	Whey protein (from dairy) can be an issue for lactose intolerance or dairy allergies.	Pea protein is often hypoallergenic, but soy and nut allergies are common.
Sustainability	Higher environmental impact.	Lower environmental impact.

When is Protein Powder for Kids a Good Idea?

For most healthy, active children, protein powder is unnecessary. However, there are specific scenarios where a pediatrician or registered dietitian might recommend a supplemental shake. This might apply to children who are significantly underweight, have increased needs due to a medical condition, or are elite athletes.

How to choose a safe protein powder for kids:

Consult a Professional: Always speak with a healthcare provider first to determine if a supplement is needed and to confirm the appropriate dosage.
Check for Third-Party Testing: Look for brands that have certifications confirming the product is free from heavy metals, contaminants, and other harmful additives.
Avoid Unnecessary Additives: Steer clear of artificial sweeteners, excessive added sugars, and stimulants like caffeine.
Match Age and Needs: Choose formulas designed specifically for children, as adult products can have inappropriate protein levels and other ingredients.

Excessive protein intake can place a metabolic burden on a child's kidneys and is often unnecessary, leading to the excess calories being stored as fat. The best approach remains a whole-food-first philosophy.

Conclusion

When it comes to what type of protein is best for kids, variety and balance from whole food sources are the undisputed winners. Both animal-based proteins, such as eggs, lean meats, and dairy, and plant-based options, including beans, legumes, and nuts, provide the necessary building blocks for a child's growth and development. Protein powders should be used with caution and only under professional guidance for children with specific nutritional needs. By focusing on incorporating a wide range of protein-rich foods into meals and snacks, parents can ensure their children are well-nourished and on the path to lifelong health.

Many plant proteins, such as beans and grains, are not complete on their own. However, by combining a variety of plant sources throughout the day, like rice and beans, a child can get all the essential amino acids they need.

Whey protein is naturally a complete protein and highly bioavailable. Plant protein, especially if from a variety of sources or a high-quality blend, is also excellent, particularly for those with dairy sensitivities. Both are effective, and the best choice depends on the child's specific dietary needs and preferences.

Yes, children can absolutely get enough protein without eating meat. Excellent vegetarian and vegan sources include eggs, dairy (if not vegan), legumes, nuts, seeds, and soy products like tofu and edamame.

Easy protein-packed snacks include hard-boiled eggs, cheese sticks, Greek yogurt parfaits, hummus with veggie sticks, and energy bites made with oats and nut butter.

Protein powder is generally not necessary for most healthy children. It should only be considered under the guidance of a healthcare provider for specific situations, such as growth issues, illness, or for young athletes with very high caloric needs.

Excessive protein can strain a child's kidneys, lead to dehydration, and cause unwanted weight gain from excess calories. A balanced diet is always the safest approach.
