“Nutrient Sources and Significance”Your team in the Fuel4Success challenge has dietary needs as diverse as their personalities. Ultimately, it's up to you to create a meal that suits the needs and goals of each of them. Playing the engaging game "Meal Maker", allows you to combine many different world foods to satisfy the individual dietary needs of each of your team members while, at the same time, keeping them happy with a tasty meal. As you plan their meals, your goal is to keep the nutrition bars up in the green "healthy zone" and out of the red "danger zone". How do you do that? By understanding the best nutritional balance for each member of your team and combining the right foods of course! Click on the link to access the GameScape.

Recorded intake of protein, carbohydrates, and lipids

o Which foods in your recorded daily intake provide protein? Which provide carbohydrates? Which provide lipids?

o Review how your recorded protein, carbohydrate, and lipid intake compares with the recommendations of the dietary reference intake. If your recorded protein-carbohydrate-fat intake was too high or too low, which foods might you add or remove to achieve your goal and keep other nutrients in balance?

o Is the protein in each food you ate complete or incomplete, combining to become complementary? Why is this important?

o How much of your daily recommended protein, carbohydrates, and lipid intake did you achieve? If your macronutrient intake is insufficient or excessive, what might you do to bring it into the recommended range? Provide specific recommendations.

Macronutrient intake rangeso Is macronutrient intake within the recommended range important?

What are the effects of too much or too little of a macronutrient? What happens if you consistently eat too little protein? What happens if you eat too few carbohydrates? What happens if you eat too few lipids?

Fiber intake rangeso Does your fiber total meet 100% of the recommendation for you, as

calculated at iProfile?o Does your diet meet the minimum number of servings of foods from

each fiber-containing group? If not, which of the fiber-containing groups--fruits and vegetables--fell short of the recommended intake?

o Which specific foods provide the most fiber in your meals? Which provide the least? Identify trends in your food choices that might affect your fiber intakes.

Dietary modificationso What changes might you make to increase the fiber in your diet?o How might insufficient or excessive amounts of proteins,

carbohydrates, fats, or fiber contribute to health or illness? Provide examples.

o What have you learned about your diet?
