Eat your vegetables. No dessert until you’ve cleaned your plate. If you want a snack, you can have a piece of fruit. Any of these phrases sound familiar? When we’re kids, we hear a lot of these phrases as we’re learning good eating habits. As we age, these habits become second nature (and often even enjoyable, as we discover how good we feel when we eat a healthy diet). What we might not expect, though, is that this healthy-eating focus can slip away as we age – and can have serious consequences.
