- the foundation of federal nutrition policy and are developed by the USDA and the DHHS ; - science-based - intended to reduce the number of Americans who develop chronic diseases such as hypertension, diabetes, cardiovascular disease, obesity, and alcoholism. - promote health and to reduce the risk of chronic disease through diet and physical activity; all ages
Dietary Guidelines for Americans, 2010
73
Main objective of Dietary Guidelines for Americans
is to encourage Americans to balance calorie intake with physical activity to manage weight
74
There are two major differences between the two sets of guidelines: Sugar. In the 2010 guidelines, the recommendation was simply to limit sugar, but the 2015 guidelines now advise you to limit added sugar to no more than 10 percent of your total calorie intake for the day. Cholesterol. In 2010, cholesterol was considered a nutrient that we should reduce in our diets, with an included recommendation to consume no more than 300 milligrams of dietary cholesterol. Today, new research has found that dietary cholesterol intake does not influence blood cholesterol levels, so there is no recommended restriction on cholesterol in the new guidelines.
