Nutrient-Dense Versus Energy-Dense Foods
American Diet Too many calories and too much: Too few: fat, added sugars, refined grains, and sodium Too few: vegetables, fruits, whole grains, and fat-free or low-fat milk and milk products
The important thing to remember is that you can enjoy all foods as part of a healthy diet as long as you do not over do on: Fat Added sugar Salt and Alcohol
Dietary Guidelines for Americans (DGA)
Updated every 5 years by the US Department of Agriculture (USDA) and US Department of Health and Human Services (HHS) Based on the latest science-based information about nutrition and health Core of federal food and nutrition education programs
The guidelines provide advice on how to eat healthfully and reduce the risk of chronic disease. The most recent guidelines stress the importance of the consumption of nutrient-dense foods and balancing calorie intake with the amount expended throughout the day in physical activity. They suggest consuming more: fruits, vegetables, whole grains, fish, seafood, beans, nuts and seeds, and fat-free and low-fat dairy products.
The guidelines recommend getting no more than 15 percent of one’s daily calories from: solid fats and added sugars (SoFAS) and eating fewer foods with refined grains and less sodium

Food Labels Label is one of the most important tools you can use to eat healthfully By law, all labels must contain: Product name Manufacturer’s name and address Uniform serving size Amount in the package Ingredients in descending order by weight Nutrient components Percent Daily Value
Food Labels By law, all labels must contain: Nutrition Facts panel: a detailed breakdown of the nutritional content of a serving of a food that must appear on virtually all packaged foods sold in the United States All food labels are required to bear an ingredients list. Ingredients list: a listing of the ingredients in a food, with items listed in descending order of predominance by weight.

Using the Food Label Calculate the Percentage of Calories from Fat 12 g of fat 12 g fat * 9 kcal/g = 108 kcal 108 kcal / 360 total kcal = 0.30 0.30 x 100 = 30% calories from fat Percentage of calories from carbohydrates = 54% Percentage of calories from proteins = 14%

Daily Value Daily Values: is based on 2000 calories Designed for food lebels use for comparison The % Daily Values that appear on food labels tell you the percentage of a nutrient that a serving of the food contributes to a healthful diet
Food Labels Nutrient content claims: claims such as: “low-fat” “low-calorie” “good source” 1. Low Calorie- 40 calories or fewer 2. Reduced or less-25% lower than “regular” 3. Lean- Less than 10g of fat 4. Extra Lean- Less than 5g of fat 5. Good Source-10 to 19% of the DV 6. High in – 20% or more of the DV
Claims Made on Foods and Supplements
Food Labels Health claim: -Calcium and reduced risk of osteoporosis A statement on the food label linking the nutritional profile of a food to a reduced risk of a particular disease, such as osteoporosis or cancer. Manufacturers must adhere to strict government guidelines when making such claims. -Calcium and reduced risk of osteoporosis -Sodium and reduced risk of hypertension -Sugar Alcohols and reduced risk of tooth decay -Soluble fiber and reduced risk of heart disease
