The 2015 Dietary Guidelines: The Science of Healthy Eating Patterns


There are lots of reasons to follow the healthy eating pattern strategies laid out by the latest edition of the Dietary Guidelines for Americans. To start, let's take a closer look  at the science behind these recommendations.

According to the guidelines, “Strong evidence shows that healthy eating patterns are associated with a reduced risk of cardiovascular disease (CVD). Moderate evidence indicates that healthy eating patterns also are associated with a reduced risk of type 2 diabetes, certain types of cancers (such as colorectal and postmenopausal breast cancers), overweight, and obesity. Emerging evidence also suggests that relationships may exist between eating patterns and some neurocognitive disorders and congenital anomalies.”

Now let's get into the nitty gritty -- the components of healthy eating patterns.

The post The 2015 Dietary Guidelines: Eating Patterns covers the basics of those components, and the guidelines explain that “research has shown that vegetables and fruits are associated with a reduced risk of many chronic diseases, including CVD, and may be protective against certain types of cancers. Additionally, some evidence indicates that whole grain intake may reduce risk for CVD and is associated with lower body weight. Research also has linked dairy intake to improved bone health, especially in children and adolescents.” How great is that?
