In a recent study at University College of London, scientists determined that almost 80 percent of children's tendency to dislike unfamiliar foods was inherited. Dr. Lucy J. Cooke stated:
"Parents can be reassured that their child's reluctance to try new foods is not simply the result of poor parental feeding practices, but it is partly in the genes."
The study used twins as subjects in order to separate the effects of genes and environments — identical twins share 100 percent of their genes, fraternal twins share about 50 percent, while both share the same environment.
Once the results were in, they discovered that the identical twins were more likely to share food neophobias than the fraternal twins. Simple translation: identical twins have the same phobias, while fraternal twins have different ones, proving that food neophobias are related to genes.
However, just because it is in someone's genes, doesn't mean they can't overcome it. Research has also shown that the more frequently children are offered a particular food, the more likely they are to enjoy it.
So start offering your little ones brussel sprouts everyday and who knows, they might start liking them eventually.
