Genetics is partially responsible for dictating whether we love or loathe vegetables, according to a King’s College London study published in Twin Research and Human Genetics. Findings showed a link between genetics and diet: identical twin pairs, who share 100% of their genes, had higher odds of exhibiting the same scores across nine dietary indices, even after adjustments for body mass index and exercise levels, compared with nonidentical twin pairs, who share 50% of their genes. This highlights the complex relationship between genetic and environmental factors in our overall eating habits.
