Taste for meat and fish is inherited

Children inherit their taste for high-protein food like meat and fish from their parents, a study has found. However, any enjoyment of vegetables and puddings is more likely to be influenced by their environment.

Cancer Research UK scientists studied the food preferences of more than 200 pairs of same-sex twins and found that the “heritability factor” is stronger with high protein foods than any other kind.

Professor Jane Wardle, of Cancer Research UK’s health behaviour unit, who led the study, said: “Finding out more about why children like and dislike foods is important in helping us understand the problems of obesity. Childhood obesity can lead to a number of health problems in later life including cancer.”

The study gave questionnaires to the mothers of 103 pairs of identical twins and 111 pairs of non-identical twins.

Identical twins share all their genes and so comparing their food preferences with those of non-identical twins (who share only about half their genes) highlights the difference between what is inherited and what is influenced by environment, the researchers said.

Mothers of children aged between four and five were given a list of 77 foods divided into four different categories.

The meat and fish category included beef, lamb, pork, chicken, bacon, fried fish, white fish and oily fish and results showed high heritability.

The dessert food category included cream, cakes, pastries, fruit pie, sponge pudding, custard and dairy desserts and results showed only moderate heritability.

The vegetables and fruit category included broccoli, cabbage, carrots, cauliflower, green beans, mushrooms, onions, parsnips, salad greens, tomatoes, apples, bananas, grape, strawberries, peaches, citrus fruits and fruit juice. The results in this category found only modest heritability.

The study also showed that there was a trend for girls to like vegetables more than boys.

Prof Wardle added: “This is the first study to include significant numbers of protein foods and the first to show high heritability for these. But it is not clear exactly what environmental factors are influential when it comes to fruit, vegetables or puddings.

“It might be that children who witness their parents show enthusiasm or distaste for certain types of vegetables or puddings are likely to follow suit. Or it might be that if a particular food is always available children learn to like it. For instance if a fruit bowl is always full of bananas children might think of them as being a favourite food.”
