Nutrition. Why is it important?. Why is limiting fat intake important?. The 2005 U.S. dietary guidelines recommend that children and teens ages 4–18 get between 25% to 35% of their daily calories from fat. We need good fats to absorb essential vitamins like Vitamins A, D, K, and E.

  1. Nutrition Why is it important?

  2. Why is limiting fat intake important? • The 2005 U.S. dietary guidelines recommend that children and teens ages 4–18 get between 25% to 35% of their daily calories from fat. • We need good fats to absorb essential vitamins like Vitamins A, D, K, and E. • Saturated and Trans fats are bad – usually are solids at room temperatures. These fats are bad for our heart. • Butter, shortening, fat on meat • Often found in packaged “snacks” • Unsaturated fats are better! We should try to get our daily fat amounts from this type. They are usually liquids at room temperature. • Peanut, sesame, and olive oils.

  3. Remember, we should only be getting 25 – 35% of our daily calories from fat! If we do choose a food that is high in fat, we should try to make up for it elsewhere by eating other foods low in fat calories.

  4. Fast Food Junkies Section 1: Writing Linear Equations

  5. On your worksheet • Choose menu items • Enter the number of calories under the first column • Enter the number of fat calories under the second column McDonald's Nutrition Facts

  6. Non-fat Calories If we know the number of calories and the number of fat calories, how would we find the number of non-fatcalories? Calories - Fat from Calories Non-Fat Calories

  7. Percentage of Fat Entire circle represents the total amount of calories making up the food - 100% (the entire pie). Non-fat calories represent the portion of non-fat calories compared to the entire amount – 25% (1/4 of the entire pie). The percentage of fat is the portion of the pie that is covered by fat calories – 75% (3/4 of the pie). Calculating percentage of fat: Fat calories/total calories x 100 = percentage of calories 75/100 x 100 = 75%  Don’t forget to use the percent sign. Non-Fat Calories 25 75 Fat Calories Total Calories (100)

  8. Fast Food Junkies Section 2: Using Microsoft Excel’s Formula Tool

  9. Using Microsoft Excel • Open Microsoft Excel. • Type your headings in Row 1: • Food, Calories, Fat Calories, Non-fat Calories, Percentage of Fat. • Type the food items you chose in column 1 under the Food heading (use your handout for an example). • Type the calories and fat calories from the table on your worksheet. • Save your worksheet before we continue working.
