Fruits Consumption

Question 1

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?

Answer the questions posed in the Nutri-Case provided above. Refer to the “in depth Cancer” discussion on pages 292-299 in “Nutrition: An Applied Approach” 5th edition (pp. 301-309 in the 4th edition) for further information.

Question 2

1. Astronauts need sound nutrition to maintain health. What are the four dietary principles you would recommend astronauts to follow when they plan their diet? (hint: characteristics of a healthy diet)

2. Provide an idea you may have to help astronauts eat well during space flight. Please use your imagination and creativity. There is no right or wrong answer – you can talk about anything related to food and nutrition in space.
