Parenting a toddler or preschooler often means navigating picky eating and endless snack requests. That’s where small, simple changes can make a big difference in your child’s nutrition. Enter these research-backed tips to help kiddos eat healthier!

Tip #1: Boost fiber for happy tummies.

Fiber is a superhero nutrient for young children. Not only does fiber keep things moving in the digestive tract (preventing dreaded toddler constipation), it also helps kids feel full on healthy foods—and even guards their long-term health. In fact, a fiber-rich diet may help prevent constipation and reduce the future risk of heart disease, certain cancers, and obesity. Unfortunately, most children (and adults!) don’t get enough fiber. The American Academy of Pediatrics (AAP) suggests a simple guideline: offer about “age + 5” grams of fiber per day. For example, a 3-year-old would need roughly 8 grams of fiber daily.

Easy fiber-rich foods to add to your child’s plate include:

  • Fruits: apples with skin, pears, berries, bananas
  • Vegetables: carrots, peas, broccoli, sweet potatoes
  • Whole grains: whole wheat bread, oatmeal, whole-grain cereal, brown rice
  • Beans and lentils: black beans, chickpeas, lentil soup (even a few spoonfuls count!)

Offer plenty of water alongside fiber-rich foods to help everything “go down” smoothly. Over time, a fiber-rich diet will not only keep your kiddo regular in the potty department, but also nurture healthy gut bacteria and overall wellness (some studies even link high fiber intake in childhood to lower rates of chronic illness later on).

Tip #2: Avoid blackened or charred foods.

That black, charred crust on grilled or fried foods might taste savory, but it’s not great for little ones. When foods (especially meats) are cooked at very high temperatures or over an open flame, they can form compounds called HCAs and PAHs—big names that have been linked to cancer in animal studies. While the science in humans isn’t 100% settled, research has found that eating lots of charred, well-done meats is associated with higher risks of certain cancers later in life. The safe bet for your child: Cook foods thoroughly (to kill bacteria) but avoid burning or charring them.

Practical tips: If a piece of toast or meat does get blackened, simply scrape or cut off the charred parts before serving. Instead of high-heat charring, use gentler cooking methods when possible. Try baking chicken tenders in the oven, steaming veggies, or sautéing foods on medium heat. You’ll still get yummy flavors without the smoky char, and you’ll be protecting your little one from ingesting those questionable chemicals. (Bonus: Gentler cooking often preserves more nutrients, too!)

Tip #3: Trade the Teflon for safer cookware.

We all love convenience, but non-stick pans can introduce hidden risks into your family’s diet. Traditional non-stick cookware (like Teflon pans) is often made with chemicals called PFAS— nicknamed “forever chemicals” because they linger in our bodies and environment. Research suggests that exposure to certain PFAS may affect children’s development, immune system, and even increase the risk of some cancers. Even more immediately, if non-stick pans overheat, they can release toxic fumes, which are bad for birds (Teflon fumes can be deadly to pet birds) and not great for tiny humans either. (Related: The Dark Side of Black Plastics)

The healthier swap: Cook with PFAS-free, non-toxic cookware. Great options include cast iron skillets, stainless steel pots, ceramic-coated pans, and oven-safe glassware. These may require a bit more oil or butter to prevent sticking, but they won’t leach harmful chemicals into your child’s food. Experts specifically recommend using cast iron, stainless steel, stone, or ceramic instead of conventional non-stick. As a bonus, a well-seasoned cast iron pan is naturally non-stick and even adds a little iron to your food! So, when making pancakes or scrambling eggs for your kiddo, consider reaching for the iron skillet and cook with peace of mind.

Tip #4: Make sure your child gets enough vitamin D.

Vitamin D is often called the “sunshine vitamin,” and it’s essential for your child’s growth. Little kids need vitamin D to absorb calcium and build strong bones and teeth. Without enough, they’re at risk for rickets (soft, weak bones). Vitamin D also supports a healthy immune system and has been linked to a good mood and even lower risk of depression in later life. The trouble is, many children don’t get sufficient vitamin D from diet or sun alone; roughly 15% of kids ages 1 to 11 are deficient.

To boost your tot’s vitamin D: Know the goal. Pediatricians recommend 600 IU of vitamin D per day for children over 1-year-old (infants under 12 months need 400 IU). Many kids can meet this through a combination of diet and a daily supplement (drops or chewable vitamins—ask your pediatrician what’s right for your child). Vitamin-D–fortified milk is a big helper. Two cups of fortified milk provide about 200 IU. Other food sources include fatty fish (like salmon), egg yolks, and fortified cereals. And don’t forget safe sunshine: playing outdoors helps our bodies produce vitamin D, though remember to use sunscreen for extended play to protect their sensitive skin. If you’re unsure whether your child is getting enough, talk to your pediatrician. They may recommend a vitamin D supplement, especially if your little one is a picky eater or doesn’t drink much milk. Keeping up with vitamin D is a simple step that keeps those growing bones strong and supports your child’s overall health.

Tip #5: Cut back on salt.

Many of us grew up salting our food out of habit, but young children’s bodies are much more sensitive to sodium. In fact, for toddlers, the recommended sodium limit is only around 1,200 mg per day (that’s less than half a teaspoon of salt), and about 1,500 mg for 4- to 5-year-olds. However, American kids often eat far more – the average child (ages 2 to 18) consumes about 3,300 mg of sodium daily. Why does this matter? Too much salt in childhood can raise blood pressure even in little ones. Kids with high-sodium diets are ~20% more likely to have elevated blood pressure than kids who eat less salt. High blood pressure in childhood can lead to heart health issues down the road. Plus, developing a taste for salty foods early makes it harder to enjoy naturally flavored foods.

The solution: Go easy on the saltshaker and watch out for sneaky high-sodium foods. Many processed foods and kid favorites (like chicken nuggets, hot dogs, pizza, and chips) are packed with salt. Try to choose low-sodium versions of staples (opt for “no added salt” canned veggies, or rinsed low-sodium beans, for example). Cook at home when you can, flavoring foods with herbs, spices, garlic, or lemon juice instead of extra salt. Your child’s taste buds will adjust – and here’s a fun fact: children’s salt preferences are shaped early. If they’re not used to super salty snacks, they won’t miss them. In other words, starting now with lower sodium foods can help your kid prefer healthier options later in life. Gradually reduce salty snacks and instant meals, and celebrate hydration with water (instead of sports drinks or salty soups). Over time, your whole family’s hearts will thank you!

Tip #6: Slow down the sugar rush.

We all know kids love sweets – but too much sugar, especially from sugary drinks, can spell trouble for tiny bodies. Sweet beverages like soda, fruit punch, lemonade, and even 100% fruit juice in large amounts flood kids with sugar minus the fiber and nutrients of whole foods. Frequently drinking sugar-loaded drinks is associated with weight gain, type 2 diabetes, heart disease, tooth decay, and more. That’s why experts say children under 2 should have no added sugars in their diet at all. Even for ages 2 to 5, it’s best to limit added sugar to very small amounts. Juice can be an occasional source of vitamins, but the American Academy of Pediatrics now says no juice for babies under 1, and to cap 100% fruit juice at 4 ounces a day for toddlers (1 to 3 years) and 4 to 6 ounces for 4 to 5 year-olds. For reference, 4 ounces is just half a cup. Those sippy cups can hold much more, so be mindful of refills.

So how do you tame your tot’s sweet tooth without tears? Try these parent-tested tips:

  • Offer water and milk first. Make water (or plain milk) the go-to drink at meals and snack time. Save juice or sweet drinks for rare treats, if at all.
  • Dilute juices when you do serve them. Mix water into your child’s juice to cut the sugar in each cup – they likely won’t even notice a gradual change!
  • Flavor water naturally. Infuse water with slices of strawberry, orange, cucumber, or mint to make “fun water” that has a hint of sweetness without added sugar. Kids love the colors and mild taste.
  • Use a “touch” of sweetness if needed. If your child absolutely refuses plain water, you can add a tiny splash of 100% fruit juice to water for flavor. For children over 1 year (never before due to botulism risk), a drop of honey in a cup of warm water or herbal tea can lightly sweeten it – but remember even honey is a form of sugar, so use sparingly. Often just modeling enjoyment of water yourself and having patience works wonders. When your child is thirsty enough, they will drink what’s offered.

And what about treats? It’s fine to enjoy birthday cake or ice cream occasionally. Just keep everyday sugar low. Instead of cookies or candy, try offering naturally sweet foods like cut-up fruit (watermelon, berries, apple slices with peanut butter) for dessert. You’ll satisfy your little one’s sweet cravings while nourishing their body. Over time, their taste buds will adapt to crave less sugar, making healthy choices easier as they grow.

Tip #7: Cook With Heart-Healthy Olive Oil

When it comes to fats, not all are created equal, and olive oil is one of the best choices for your child’s growing body! Rich in monounsaturated fats and packed with antioxidants, high-quality olive oil supports brain development, heart health, and even helps absorb fat-soluble vitamins like A, D, E, and K . In fact, research shows that introducing healthy fats early in life can promote better cholesterol levels and reduce the risk of heart disease later on.

The American Academy of Pediatrics and nutrition experts recommend that toddlers and young children get about 30 to 40% of their calories from healthy fats, especially from sources like olive oil, avocado, and nuts . Olive oil’s smooth, mild taste makes it super kid-friendly:

Easy ways to use olive oil:

  • Drizzle a little over roasted veggies or cooked pasta
  • Sauté fish, chicken, or tofu in olive oil instead of butter
  • Mix olive oil into mashed potatoes instead of cream
  • Use olive oil-based dressings for salads and grain bowls (skip the heavy bottled dressings)

Tip #8: Serve the rainbow.

One of the best things you can do for your child’s nutrition is to offer a wide variety of whole foods. Eating a colorful mix of fruits, veggies, whole grains, proteins, and healthy fats ensures your kiddo gets a broad range of vitamins and minerals. Plus, variety itself can encourage better eating. Research shows that repeatedly offering an assortment of veggies boosts children’s acceptance and intake of those veggies. In one study, families who rotated several different vegetables saw their kids double their veggie consumption after a few weeks, compared to families who offered the same veggie over and over. The lesson: keep introducing new healthy foods (even if it takes a dozen tries!).

Easy ways to add variety: Rotate the fruits and veggies you serve (bananas and apples one week, berries and peaches the next; carrots and peas one day, zucchini and bell pepper strips another). Include a mix of protein sources—not just chicken nuggets! Try beans, scrambled eggs, yogurt, tofu, fish, or lean meats. Opt for whole grains like whole wheat pasta, brown rice, or quinoa for more nutrients and fiber. And don’t be afraid to introduce flavorful herbs and spices early; mild spices, garlic, or cinnamon can make healthy foods more exciting and help your child become an adventurous eater. Remember, healthy eating in childhood promotes proper growth and can help prevent many health issues later on. By serving a variety of wholesome foods and modeling enjoyment of them yourself, you’re teaching your little one that food is fun, delicious, and nourishing. Even if peas get tossed on the floor a few times, don’t give up. Every exposure counts, and one day your child may surprise you by asking for “more broccoli please!” 

Final Thoughts on Healthy Eating

Improving your young child’s nutrition doesn’t have to be overwhelming. Small changes, made consistently, truly add up. Swap that second cup of juice for water. Offer an extra spoonful of veggies at dinner. Use a stainless steel pan instead of a Teflon one. Over time, these habits become second nature. By boosting fiber, vitamin D, and variety—and cutting down on charring, chemicals, salt, and sugar—you’re not only fueling your little one’s growth today, you’re also instilling healthy habits that can last a lifetime. Cheers to happy, healthy eating for your family!
