Whether it’s lactose or kale, quinoa or turmeric (curcumin), you have to ask whether these were foods common at the table when you, your parents, or your grandparents were growing up.

The potential problems are intolerances (for example, an inability to break down the lactose sugar in milk) or autoimmunities, such as the reaction to gluten-rich foods like bread and pasta observed in people with celiac disease.
