To develop each edition of the Dietary Guidelines for Americans, HHS and USDA collaborate through a 3-phase process. The Departments of Health and Human Services and Agriculture publish a new edition of the Dietary Guidelines for Americans every 5 years.
Review of Current Scientific Evidence
Thus, very few existing nutrition-focused systematic reviews were available for the 2010 Advisory Committee to use. The Advisory Committee used this method to estimate the effect on diet quality of possible changes in types or amounts of foods in the USDA food patterns it was considering recommending.
Development of the Dietary Guidelines for Americans
Throughout, the 2015-2020 edition of the Dietary Guidelines notes the strength of evidence supporting the recommendations. The evidence described in the dietary guidelines also reflects an understanding of the difference between association.
Implementing the Dietary Guidelines for Americans
Key Elements of Healthy Eating Patterns
Eating pattern - The combination of foods and beverages that make up an individual's complete dietary intake over time. A new edition is published every 5 years to reflect advances in scientific knowledge and translate current science into healthy food-based guidance to promote health in the United States.[2] The process of developing the dietary guidelines has also evolved and includes three phases. In addition, the chapter provides two variations of the American-style healthy eating pattern as examples of additional healthy eating patterns—the healthy Mediterranean eating pattern and the healthy vegetarian eating pattern.
Two additional USDA food patterns—the Healthy Mediterranean Eating Pattern and the Healthy Vegetarian Eating Pattern—are found at the end of this chapter and reflect other eating styles (see Appendix 4. Managing caloric intake is fundamental to achieving and maintaining caloric balance—the balance between the calories , consumed from foods, and the calories consumed from metabolic processes and physical activity.Caloric intake is strongly associated with sodium intake (ie, the more foods and beverages people consume, the more sodium they tend to consume).
28] The following are reference drinks equivalent to one alcoholic drink: 12 fluid ounces of regular beer (5% alcohol), 5 fluid ounces of wine (12% alcohol), or 1.5 fluid ounces of 80 proof distilled spirits (40% . alcohol). [29] The amount of alcohol and calories in drinks varies and should be considered within the limits of healthy eating patterns so that calorie limits are not exceeded. Acculturation – The process by which individuals who immigrate to a new country adopt the new culture's attitudes, values, customs, beliefs, and behaviors. Calorie Balance – The balance between calories consumed through eating and drinking and calories consumed through physical activity and metabolic processes.
DASH Eating Plan – The DASH (Dietary Action to Stop Hypertension) eating plan is an example of a healthy diet. Eating pattern (also called "dietary pattern") - The combination of foods and beverages that make up an individual's complete dietary intake over time. Ounce-equivalent (oz-eq) - The amount of a food product considered to be equal to 1 ounce from the food group grains or protein foods.
Shifts Needed To Align With Healthy Eating Patterns
Everyone Has a Role in Supporting Healthy Eating Patterns
Physical Activity Guidelines for Americans
In addition to eating a healthy diet, regular physical activity is one of the most important things Americans can do to improve their health. The Department of Health and Human Services provides a comprehensive set of recommendations for Americans on the amounts and types of physical activity needed each day. Youth ages 6 to 17 need at least 60 minutes of physical activity per day, including aerobic, muscle-strengthening, and bone-strengthening activities (see Table A1-1 for additional details).
These can be used to help motivate the consumer audience to make healthy physical activity choices. As part of their 60 or more minutes of daily physical activity, children and adolescents should include muscle-strengthening physical activity on at least 3 days of the week. As part of their 60 or more minutes of daily physical activity, children and adolescents should include bone-strengthening physical activity on at least 3 days of the week.
Some physical activity is better than none, and adults who participate in any physical activity reap several health benefits. Older adults should determine their level of physical activity effort in relation to their level of fitness.

USDA Food Patterns: Healthy U.S.-Style Eating Pattern
Strong evidence shows that healthy eating patterns are associated with a reduced risk of cardiovascular disease (CVD). The recommended amount of vegetables in the US Healthy Eating Pattern at the 2,000-calorie level is 2½ cups of vegetable equivalents per day. The recommended amount of fruit in the 2,000-calorie American Healthy Eating Pattern is 2 cup equivalents per day.
100% fruit juice.” The amounts of fruit juice allowed in the USDA food patterns for young children are consistent with the recommendation from the American Academy of Pediatrics that young children consume no more than 4 to 6 fluid ounces of 100% fruit juice per day. [12] Fruits with small amounts of added sugars can be accommodated in the diet as long as calories from added sugars do not exceed 10 percent per day and total calorie intake remains within limits. The recommended amount of grains in the American-style Healthy Eating Pattern at the 2,000-calorie level is 6 ounce-equivalents per day. The recommendation for oils in the American-style Healthy Eating Pattern at the 2,000-calorie level is 27 g (about 5 teaspoons) per day.
As explained in the next part of the chapter, additional constraints related to other dietary components apply to the formation of healthy eating patterns. Moderate coffee consumption (three to five 8-oz cups per day, or providing up to 400 mg of caffeine per day) can be incorporated into healthy eating patterns. The typical dietary patterns currently consumed by many in the United States do not meet the Dietary Guidelines.
Categories[1] allow insight into the sources of food groups and nutrient intake and are therefore useful in determining 1. the total amount consumed from all of them.
USDA Food Patterns: Healthy Mediterranean-Style Eating Pattern
Healthy Mediterranean Eating Pattern: Recommended amounts of food from each food group at 12 calorie levels. Food group[b] Daily amount[c] of food from each group (vegetable and protein food subgroup amounts are per week). For more information, see the FDA or EPA websites www.FDA.gov/fishadvice; www.EPA.gov/.
USDA Food Patterns: Healthy Vegetarian Eating Pattern
Healthy Vegetarian Eating Pattern: Recommended Amounts of Food from Each Food Group at 12 Calorie Levels. The total legumes in the Models, in cup-eq, is the amount in the vegetable group plus the amount in the protein food group (in oz-eq) divided by 4:
Glossary of Terms
Dietary fiber consists of non-digestible carbohydrates and lignin that are intrinsic and intact in plants (i.e. the fibers that naturally occur in foods). Fortification – The addition of specific nutrients (i.e. iron, thiamin, riboflavin and niacin) to refined grain products to compensate for nutrient losses that occur during processing. Other dietary components, such as dietary fiber, while not essential, are also considered nutrients.
Trans fatty acids are also naturally present in foods that come from ruminant animals (eg, cattle and sheep), such as dairy products, beef and lamb. Hypertension makes the heart work too hard, and the high force of blood flow can damage arteries and organs, such as the heart, kidneys, brain and eyes. Ideally, these foods and beverages are also in forms that contain natural ingredients, such as dietary fiber.
Many foods are naturally high in oils, such as nuts, olives, some fish and avocados. Some tropical oils, such as coconut and palm, are considered solid fats because of their fatty acid composition.

Federal Resources for Information on Nutrition & Physical Activity
The following federal government resources provide reliable, science-based information about diet and physical activity and an evolving array of tools to help Americans make healthy choices.
Alcohol
Binge drinking is consuming 4 or more drinks for women and 5 or more drinks for men in about 2 hours. Excessive alcohol use, including binge drinking (4 or more drinks for women and 5 or more drinks for men in about 2 hours); drinking heavily. Excessive alcohol consumption is responsible for 88,000 deaths annually in the United States, including 1 in 10 deaths.
In 2006, the estimated economic cost to the United States of excessive alcohol consumption was $224 billion.[4] Binge drinking accounts for more than half of the deaths and three-quarters of the economic costs of binge drinking [1], [5]. Binge drinking is associated with a number of health and social problems, including sexually transmitted diseases, unintended pregnancy, accidental injuries, and violent crime.[8] Drinking during pregnancy, especially in the first few months of pregnancy, can cause negative behavioral or neurological consequences in the offspring.
People who mix alcohol and caffeine can drink more alcohol and become more drunk than they realize, increasing the risk of alcohol-related side effects. Contribution of excessive alcohol consumption to death and years of potential life lost in the United States.

Food Safety Principles & Guidance
Attention must be paid to food segregation at every step of food handling, from purchase to preparation to serving. Always use a clean cutting board for fresh produce and a separate one for seafood, raw meat and poultry. Seafood, meat, poultry, and eggs should be cooked to the minimum recommended internal temperature safe to destroy harmful microbes (see Table A14-1).
A food thermometer should be used to ensure that food is cooked safely and that cooked food is kept at safe temperatures until it is eaten. In general, the food thermometer should be inserted into the thickest part of the food, without touching the bones, fat or grate. The manufacturer's instructions should be followed for the time required to measure the temperature of foods.
The temperature should be measured with a clean food thermometer before removing the meat from the heat source. Pregnant women, infants and young children, older adults and people with weakened immune systems should only eat foods containing seafood, meat, poultry or eggs that have been cooked to the recommended safe minimum internal temperature.
