Healthy Fats Explained for Kids: The Newest Food Group

MyPlate, the 2011–2025 federal icon, had five food groups and no spot for fat. The Dietary Guidelines for Americans, 2025–2030 added a sixth group, Healthy Fats. It sits at the top of the new upside-down pyramid alongside protein and dairy. For kids, the big idea is simple: fat is a nutrient the body needs, and many familiar whole foods contain it.

What fat does in the body

Explained for kids ages 6–12, based on MedlinePlus (from the U.S. National Library of Medicine):

• Energy. Fat is one of the ways food gives your body energy to move, grow and think.
• Helping vitamins work. Some vitamins (A, D, E and K) are called “fat-soluble.” Your body absorbs them better when there’s some fat in the meal. That’s one reason a salad often comes with an oil dressing, and why avocado on toast is more than just tasty.

The guidelines also say full-fat dairy is important for children “to help meet energy needs and support brain development.”

Where healthy fats come from

The 2025–2030 guidelines say healthy fats are “plentiful in many whole foods.” They name these:

The germ in whole grains contains fat too, according to Harvard’s Nutrition Source. It’s one more reason whole grains differ from refined ones.

For cooking, the guidelines say to “prioritize oils with essential fatty acids, such as olive oil,” and list butter or beef tallow as other options. The Daily Servings guide uses 1 teaspoon of olive oil or butter as one serving, which shows how little a serving is compared with other groups.

Notice how many foods appear in two groups. Nuts, seeds, eggs, seafood and full-fat dairy all belong to another group and supply healthy fats. The site’s sorting tool accepts both answers for nuts and seeds and explains why.

What the guidelines say about limits

The guidelines say saturated fat “should not exceed 10% of total daily calories” in general. They suggest that limiting highly processed foods (such as chips, cookies and candy) helps meet that goal. They also say more high-quality research is needed to determine which types of dietary fats best support long-term health. In other words, the science is still being worked out, and it’s fair to tell older kids that.

Sources word this differently. MedlinePlus, from the National Library of Medicine, suggests trying to avoid saturated fats such as butter and lard. The 2025–2030 guidelines list butter as a cooking option but say saturated fat should generally stay under 10% of daily calories. Older kids can find “Saturated Fat” and “Trans Fat” on a Nutrition Facts label (see reading a Nutrition Facts label with kids). There’s no need to turn it into a rule for children to police.

Children don’t need to count fat grams or calories. Offering a mix of whole foods from all six groups is the practical goal.

How to talk about fat without fear

Many adults grew up hearing that fat was something to avoid. Kids may pick up that worry. A few phrases that keep things neutral:

• “Fat is a nutrient. Your body uses it for energy and to soak up some vitamins.”
• “Avocados, olives and nuts are plant foods with fat in them.”
• “Different foods have different amounts of fat, and that’s okay.”

Avoid linking fat in food to fat on bodies. That kind of message can make children anxious about eating or about their bodies. Skip comments about weight entirely.

Hands-on ideas

• Ages 6–8: Avocado scoop. An adult halves the avocado and removes the pit, and the child scoops it out with a spoon and mashes it. Scooping avocado an adult has halved is listed as a job for ages 5–7 by the Academy of Nutrition and Dietetics. Spread it on a whole-grain tortilla or toast.
• Ages 8–10: Paper-bag test. Rub a small piece of brown paper with a slice of avocado, an olive, a pinch of peanut butter (only if no one is allergic), a cracker and an apple slice. Let them dry, then hold them up to a window. Spots that stay see-through show fat. Record results in a table. This is a looking activity, not an eating one.
• Ages 9–12: Two-group hunt. Using the sorting cards, find every food that fits in “Healthy Fats” and another group. Explain why.

Safety: Ask families about allergies before any activity with food. Peanuts, tree nuts, sesame, fish, milk and wheat (in crackers, toast and tortillas) are all major allergens, and several healthy-fat foods fall into those groups. Use nut-free swaps or picture cards when needed. If younger siblings are present, remember the AAP advises holding whole nuts and seeds until about age 4 or older, and spreading nut butter thinly. Everyone washes hands before and after handling food. Adults handle knives and pits.
