1.
2.

Dietary Strengths and Weaknesses

Think about your eating habits - not just what is on your printouts. Describe three strengths and three weaknesses about the way you currently eat. Don't list nutrients or food groups - you are evaluating the way you eat. For example, eating breakfast daily would be a strength; overconsumption of soda would be a weakness.

Strengths

Diet Planning Principles

The principles of a healthy diet are adequacy, moderation, balance and variety.

1. Using your class notes or textbook, define each diet planning principle IN YOUR OWN WORDS.

2. Then review Part 1 of your diet analysis project and your food logs. Which of the diet planning principles are you meeting and how? Which ones are you not meeting and why?

Evaluation of Family History

Mark an ‘x' if any of your immediate family members were diagnosed with the following chronic diseases BEFORE the age of 60. If you do not know your family history, mark the place an ‘x' on the line below.

I do not know my family history _________

Family Member	Cardiovascular Disease	High Blood Pressure	Diabetes	Obesity	Cancer	Osteoporosis	Other
Mother
Father
Brother(s)
Sister(s)
Maternal Grandmother
Paternal Grandmother
Maternal Grandfather
Paternal Grandfather

Evaluating Your Chronic Disease Risk

To evaluate your chronic disease risk, you must consider both genetic and lifestyle factors. Just because you do not have a family history for heart disease, doesn't mean you are not at risk for developing the disease in the future.

Use the following tables from part 1 and part 2 of the diet analysis project to answer the question below:

• Part 1: Comparison to the AMDRs, DRI, and Dietary Guidelines
• Part 1: Vitamins and Minerals - Comparing your intake to the DRIs
• Part 2: Evaluation of Family History

QUESTION: What chronic diseases might you be at risk for in 20 years if your dietary patterns remain the same? DO NOT include deficiency diseases (i.e. anemia, pellagra, etc).

In your answer, DESCRIBE the disease(s) and the associated nutrients/food components that apply to you based on information in your packet. Be sure to use complete sentences.Points will be lost if you describe deficiency diseases instead of chronic diseases.

Dietary Changes

Review your dietary habits over the past semester. Are you still eating the same way or have you made any changes since you began this class? Describe 2 facts you have learned that have already or may impact the way you eat in the future.
