What Is Healthy Eating and What Tools Can Help?
• Key principles of healthy eating:– Balance—foods from all food groups– Variety—different foods within food groups– Moderation—plan intake; control portion size
• Undernutrition: state of inadequate nutrition• Overnutrition: excess nutrients and/or calories • Malnourished: long-term outcome of consuming a
diet that doesn't meet nutrient needs– Can result from both under- and overnutrition

What Is Healthy Eating and What Tools Can Help?
• Tools to help avoid under- and overnutrition:– Dietary Reference Intakes (DRIs)
• Nutrient recommendations
– Dietary Guidelines for Americans• General dietary and lifestyle advice
– MyPlate• Food recommendations based on DRIs
– Daily Values on food labels

What Are the Dietary Reference Intakes?
• DRIs tell you how much of each nutrient you need to consume to:– Maintain good health– Prevent chronic diseases– Avoid unhealthy excesses
• Issued by U.S. National Academy of Sciences' Institute of Medicine
• Updated periodically based on latest scientific research

• Recommended intake range for energy-containing nutrients
• Carbohydrate: – 45-65% of daily calories
• Fat: – 20-35% of daily calories
• Protein: – 10-35% of daily calories

Acceptable Macronutrient Distribution Range (AMDR)
• Science-based advice• Ages 2 years and older• Promote health and
decreased risk of chronic disease through physical activity and nutrition
• Produced by USDA and DHHS– Updated every 5 years
What Are the Dietary Guidelines for Americans?

What Are MyPlate and ChooseMyPlate.gov?– Food guidance system– Shows variety of food groups – Promotes proportionality, moderation, variety,
and personalization of diet
Does your Diet Have Proportionality?• Page 39 • www.ChooseMyPlate.gov
– Interactive – How much from each food
group should you eat?• Based on your daily calorie
needs• Considers age, gender,
activity
• Nutrient density: – amount of nutrients
per calorie in a food
• Energy density: – amount of calories
compared with the weight or volume of food

What Is a Food Label and Why Is It Important?• Food labels help consumers make informed food choices• Every packaged food must be labeled with:
– Name and net weight of the food– Name and address of manufacturer or distributor– List of ingredients in descending order by weight– Nutrition information– Uniform serving sizes– How a serving of food fits into an overall daily diet– Uniform definitions for terms such as "fat-free" and "light"– Health claims that are accurate and science-based– Presence of any of eight common allergens

What Is a Food Label and Why Is It Important?
• Nutrition Facts panel: uniform listing of specific nutrients obtained in one serving– Calories and calories from fat– Total fat, saturated fat, and trans fat– Cholesterol– Total carbohydrate, dietary fiber, and sugars– Protein– Vitamin A, vitamin C, calcium, and iron
