  nutritionists, and nutrition educators
• Jointly developed by HHS/USDA every 5 years

• Getting exercise
• Meeting nutrient intakes (Dietary Reference
  Intakes) set by Institute of Medicine
• Does not emphasize dietary supplements

2. Adequate nutrients within calorie needs

• Eat a variety of nutrient-dense foods from
  different food groups (DASH eating plan)
• Limit Saturated and trans fats, cholesterol,
  added sugars, alcohol
• Key recommendations
• People over 50 yrs Vitamin B-12
• Pregnancy Iron, folic acid

2. Adequate nutrients within calorie
needs What YOU can do

• Eat breakfast each day based on the Dietary
  Guidelines eating pattern
• Fortified cereals source of nutrients and whole
  grains
• Encourages milk and fruit
• Helps raise metabolism and curb appetite to
  control weight
