Why toddlers need fiber and whole grains

Fiber is an important nutrient for growing bodies because it can aid with digestion and may help prevent constipation. It’s a type of carbohydrate found in plant foods that helps keep things moving through your little one’s gut.


However, some children don’t get enough fiber every day. Recommendations on how much fiber toddlers need vary from country to country. Some guidelines state 10-14g per day is appropriate for one to three-year-olds.


Recent studies have explored the eating patterns of toddlers around the globe. Results show that in China, toddlers (two to three years of age) consume only 4g of fiber a day, while in Russia, those of the same age average 12g in their daily diet. Toddlers in the US (aged one to two) have an average intake of 10g fiber a day, while those in Mexico (aged one to four) reach 13g per day.


The good news is that if your toddler is getting enough fiber in his diet, he’s more likely to be meeting other nutrient and energy needs too. This is because high-fiber foods, such as fruits, vegetables, and whole grains, are more nutrient-dense than foods like cakes and candy. Water is essential for fiber to pass through the body, so don’t forget to offer it to your toddler at every eating occasion.  


Whole grains: the whole story

Contrary to what some people think, whole grains and fiber are not the same thing. Foods made from whole grains contain 100% of the original grain—the bran, germ, and endosperm.


Whole grains are a healthy choice because they contain a rich balance of nutrients, including fiber, that is not lost in the food manufacturing process. Refined grains, on the other hand, may have fiber, iron, vitamins, or other nutrients stripped out by processing.


Many countries around the world are recommending more whole grains in the diets of both adults and children, with some health authorities advising that half the grains we eat should be whole grains.


Family goals

It’s not just children who may be missing out. Lots of adults fall short in their consumption of foods rich in fiber and whole grains. Lead by example and let your little one see you making healthy choices when you eat. Chances are he’ll want to copy you, then you can both enjoy the health benefits of a diet rich in fiber and whole grains.
