Why Children Hate Vegetables

A study published in 2005 by researchers at Monell Chemical Senses Center in Philadelphia suggests that a gene called TAS2R38 may be responsible for children's aversion to bitter flavors. There are two variants of the gene, one is bitter-sensitive and the other is not. Every one of us carries two of these genes in our deoxyribonucleic acid (DNA). If one or both of these genes is the bitter-sensitive genes variety, we are more likely to dislike bitter tastes.

The study in Philadelphia included 143 children and their mothers, and over 79 percent of the children had one or two copies of the bitter-sensitive gene present. Interestingly, the presence of the bitter-sensitive gene made a bigger impact on the children's food preferences than their mothers. The mothers' tastes in foods seemed to be influenced more by race and ethnic type foods than their genetic makeup. In a sense, they grew out of their aversion to bitter foods. Ethnic foods had little impact on the kids who had the bitter-senstive genes.

If this study holds true, then about 80 percent of children aren't going to be thrilled about eating broccoli and cauliflower because vegetables tend to be a little on the bitter side. It may be difficult to convince your children to eat more vegetables if they are over-sensitive to bitter flavors.

You don't need to look longingly at those 20 percent of youngsters that do like vegetables while cringing at your own bitter-sensitive kids' reactions. You can disguise the bitter taste with sauces and toppings, or you can choose starchier or sweeter vegetables such as potatoes, corn, and sweet potatoes. Hopefully as your kids grow up, their aversion to bitter tastes will ease and they'll actually start to enjoy their vegetables.

But until they grow out of hating bitter vegetables, try these recipes:

• Serve sweet glazed carrots.
• Add sweet and sour sauce to cooked broccoli.
• Sprinkle shredded cheese or cheese sauce on your green beans.

This study may help us understand why kids don't like vegetables, but remember that vegetables are still an important part of a healthy balanced diet. Keep serving vegetables to your picky eaters -- just be sure to add a side dish of patience.
