Despite learned eating behaviors that are formed in early childhood and inborn biological differences, taste preferences can be changed throughout our lives due to neuroplasticity, our brain's amazing adaptability: There is far more flexibility in our food behaviors than most think, even as we age. This is terrific news for adventurous eaters who want to expand their dinner menu ─ it's a big, tasty world out there! ─ but it's amazing news for those eager to break poor diet habits. Just as kids gradually learn to like nutritious foods, so, too, can adults readjust their taste. Many who switch from processed grain foods like white bread and white rice to whole grain types, for instance, gradually learn to prefer the nutty flavors and chewy textures. Repeated exposure ─ and a willingness to change ─ is the key.
