2015-2020 Dietary Guidelines for Americans

According to the 2015-2020 Dietary Guidelines for Americans "... nutrition and health are closely related. ... A history of poor eating and physical activity patterns have a cumulative effect and have contributed to significant nutrition- and physical activity-related health challenges that now face the U.S. population. About half of all American adults—117 million individuals—have one or more preventable chronic diseases, many of which are related to poor quality eating patterns and physical inactivity. These include cardiovascular disease, high blood pressure, type 2 diabetes, some cancers, and poor bone health. More than two-thirds of adults and nearly one-third of children and youth are overweight or obese."

Prevention of chronic disease

According to the Centers for Disease Control, diseases and conditions that are more chronic in nature such as arthritis, cancer, stroke, heart disease, diabetes and obesity are very common, costly as well as the most preventable of all health problems.

<s/pan style="font-size: 1em;">Adequate vs. inadequate nutrition plays a role in the prevention, treatment, management and/or causation of the majority of these common chronic diseases and conditions. 

Dietary risk factors associated with death and disability

A 2010 report from the U.S. Burden of Disease Collaborators identifies dietary risk factors as responsible for 26% of deaths and 14% of disability-adjusted life-years (estimated as the sum of years lived with disability and life lost to premature mortality).

Dietary risk factors included diets low in fruits, low in nuts and seeds, high in sodium, high in processed meats, low in vegetables, and high in trans fats - often a typical American diet.
