Question 1

Yesterday, Luiz had his blood lipids checked at a local campus health center and was dismayed to discover that his total cholesterol and LDL-C were high relative to the reference range and his HDL-C was low. On this morning’s news broadcast he viewed the health segment which discussed the Dr. Dean Ornish Diet. The diet was designed specifically for individuals with risk factors for cardiovascular disease (CVD). Luiz learned that the diet recommends some of the following food choices.Abundant consumption of legumes, fruits, vegetables and whole grainsModerate consumption of non-fat dairy products and non-fat or very low-fat processed foods (such as non-fat yogurt bars, very low-fat frozen dinners, etc.)Avoidance of all of the following: meats, oils, oil-containing products such as margarine and salad dressings, avocados, nuts, seeds, alcohol, sugars (including honey, molasses, and high-fructose corn syrup)The program also advises 30 minutes a day of moderate physical or three 1-hour sessions per week.The individual interviewed on the news show health segment stated that the Dr. Dean Ornish Diet plan had been proven in clinical studies to reduce the risk factors for heart disease.Compare the Dr. Dean Ornish Diet to MyPyramid. What are the main similarities? What are the main differences?Based on the recommendations for the Dean Ornish Diet, how much total fat do you think this diet would provide? Comment on the amount of essential fatty acids that the diet would provide?Do you think it is advisable for someone with a high CVD risk blood lipid profile, like Luis, to follow? Why or why not?

Question 2
Nutri-case: GUSTAVO

“Last night, there was this actress on TV talking about having colon cancer and saying that everybody over 50 should get tested. It brought back memories of my father’s cancer, how thin and weak he got before he went to the doctor, so that by the time they found the cancer it had already spread too far. But I don’t think I’m at risk. I only eat red meat two or three times a week, and I eat a piece of fruit or a vegetable at every meal. I don’t smoke, and I get plenty of exercise, sunshine, and fresh air working in the vineyard.”

Which lifestyle factors reduce Gustavo’s risk for cancer? What factors increase his risk? Would you recommend he increase his consumption of fruits and vegetables? Why or why not? If Gustavo were your father, would you urge him to have the screening test for colon cancer?
