10) Jules has decided to start a raw food diet because he read that raw foods contain enzymes that greatly aid in digestion. He believes that heating food degrades or destroys the enzymes in food, which puts burden on his body’s own enzyme production. He also read that eating food without enzymes can lead to toxicity in his body and eventually cause chronic diseases like obesity. Which of the following would be the BEST way to respond to Jules? Select one: a. Heating food does not destroy the enzymes in the food, so he can heat his food and still get the same amount of nutrients. b. Raw foods don’t contain enzymes that can digest the macronutrients within the plants, so what he read is incorrect. c. Digestion does not cause obesity because if we were truly lacking our digestive enzymes, we would be consuming fewer calories and therefore losing weight. d. Eating food without enzymes makes digestion more difficult, so the raw food diet is a great idea. Which of the following are ways that the GI tract maximizes its efficiency? Select one: a. The stomach slowly releases its contents into the small intestine. b. Villi in the stomach help to increase the available surface area for absorption. c. The body’s blood supply is diverted to the large intestine during digestion and absorption. d. A and B e. All of the above
