Thanks in part to celebrities and food bloggers, many people are talking about “clean eating.” At first, “clean eating” meant cutting back on processed food. People who followed this plan focused on cooking things from scratch and using natural ingredients. Some people who follow this plan avoid entire food groups, such as grains and dairy. This sounds healthy. But is it? According to nutrition experts, a restrictive diet can actually be less healthy. For example, avoiding dairy can cause young women to not get enough calcium. This is not good for their bones. Instead of eliminating entire food groups, it is best to focus on moderation and variety.
