Fat is one of the most widely talked about nutrients in our diet. While there are many opinions around fats in an adult diet, there’s no question that fats - including what kinds and how much -  are incredibly important for infants and toddlers.

Fat is an essential nutrient and plays many important roles in the growth and development of babies and toddlers. Fats can be found in a wide variety of foods that are on both ends of the spectrum when it comes to healthiness. Here’s what to know about fat needs for infants and toddlers, and the best places to find healthy fats for children.


Importance of Fat for Babies and Toddlers

Fat is a critical component of a young child’s diet, and as such, should make up a significant portion of the child’s caloric intake.

Fat is used as a fuel source for the body, but is also stored in fat cells for future use. The body uses fat to insulate organs, make hormones, and protect nervous system tissues. Fat also helps the body absorb fat-soluble vitamins A, D, E, and K, which are important components in a nutritious diet. Fat is important for immunity and brain function, as well as healthy eyes, hair, skin, and nails.

For babies and toddlers in particular, fats are also important,  because they provide a significant source of energy needed for growth and weight gain. Fats are calorie-dense, meaning that small servings offer a large amount of calories. Brain development also requires fat, specifically DHA, one of the omega-3 fats.

Fats are found in healthy whole foods like avocados, soy products, olives, nuts, seeds, as well as in plant oils. They are of course also found in many processed, packaged snacks, baked goods, and fast food items, which should be limited.

There are three main types of fats. Saturated fats are found in animal products like meat, eggs, and dairy products, as well as coconut and coconut oil. Diets high in saturated fat can raise blood cholesterol levels and may increase risk for heart disease.

Unsaturated fats are found in plant foods and all other plant oils. They’re considered neutral, and even beneficial for heart health.

Lastly, trans fats are unhealthy fats found naturally in many animal products. They can also be human-made and added to things like commercial snack foods, baked goods, and spreads. Trans fats are often listed as "partially hydrogenated" on the ingredient list.


Infant Fat Needs

Breast milk and infant formula are essential sources of fat for newborns and babies. During the first year of life, these sources will provide 40-50% of calories for infants. Body fat increases twice as much as muscle does between 2-6 months of age. Therefore, you might say that fat is more important than protein in the early stages of life.

Restricting fat before the age of two may actually be dangerous and is not recommended. One year old babies should be getting approximately 40% of their calories from fat.

For infants, healthy sources of fat besides breast milk and infant formula may be introduced among the first foods between 4-6 months of age. Some examples of healthy fats as first foods include mashed avocado, pureed veggies with a little olive oil, and baby oatmeal with thinned peanut butter. A good rule of thumb is to include a fat source every time your child eats.


Toddler Fat Needs

Continue to incorporate fats in meal and snack times for toddlers. Toddlers over age two should not be restricting healthy fat intake unless deemed appropriate by a doctor or dietitian. In fact, toddlers ages 2-3 years old should still be getting 30-35% - or approximately one third - of their calories from fat.

Toddlers can find healthy fats in solid foods like whole grain breads and grains, beans, legumes, soy foods, full-fat plant milks, nut and seed butters, and vegetable oils. Parents may also choose to supplement their child with a plant-based toddler formula like that from Else, which offers 9 grams of total fat in a 240 ml serving made with the formula powder.

Here are some examples of the fat content in some plant-based foods for babies and toddlers:

  • ½ an avocado = 15 grams
  • 3 oz tofu = 4 grams
  • 2 Tbsp hummus = 4 grams
  • 2 Tbsp peanut butter = 16 grams
  • 1 Tbsp olive oil = 13 grams

Fats are an important nutrient for growing infants and toddlers, and healthy fats can be found in a wide variety of plant-based foods once your child starts to wean from breast milk or infant formula. Another great way to easily incorporate healthy fats into your child’s diet is with the high-quality line of Else Nutrition’s plant-based formula.
