Concept explainers
Heart disease is the leading cause of death among people in the United States and other industrialized nations. Fast food is a major source of unhealthy fats that contribute significantly to heart disease. Imagine you’re a juror sitting on a trial where a fast-food manufacturer is being sued for making a harmful product. To what extent do you think manufacturers of unhealthy foods should be held responsible for the health consequences of their products? As a jury member, how would you vote and why?

- In a popular magazine article the author reports health benefits attributed to a particular dietary supplement. What kinds of evidence should the article cite to help you decide whether the information is likely to be accurate?arrow_forwardBile salts are synthesized from: a. Cholesterol b. Prostaglandin c. Triacylglycerol d. Ceramidearrow_forwardHigh-lipid foods are more susceptible to microbial spoilage than high-carbohydrate foods. True or False? (Justify your answer)arrow_forward
- The act of cooking a steak on a barbeque grill heats the meat to a high enough temperature to: a. promote the Maillard reaction b. kill bacteria on the surface of the meat c. denature proteins in the meat making them easier for humans to digest d. hydrolyze collagen fibers into fragments that make meat more tender and easier for humans to digest e. burn the Yule logarrow_forwardCholesterol that is made by the liver or that enters the body from food does not dissolve in blood, so it is carried through the bloodstream by lipoproteins. Low-density lipoprotein (LDL) carries cholesterol to body tissues such as artery walls, where it can form deposits associated with cardiovascular disease. Thus, LDL is often called "bad" cholesterol. High-density lipoprotein (HDL) carries cholesterol away from tissues to the liver for disposal, so HDL is often called "good" cholesterol. LDL levels were highest in the diet containing primarily ______. A. cis fatty acids B. saturated fats C. trans fatty acidsarrow_forwardFood faddists often make exaggerated claims about certain types of food. For instance, some promoters of weight-loss diets claim that carbohydrate (for example, rice) is harmful and should be omitted from the diet or intake of carbohydrate significantly reduced. There is a saying that “fats burn in the fire of carbohydrates”. What is the meaning of this? What would be the effect of a significant reduction in carbohydrate intake on the utilization of fats for energy? Cite the biochemical mechanisms that support your answer.arrow_forward
- Which of the following cannot be used to produce readily usable energy in cells? A. lipids B. carbohydrates C. proteins D. all can be usedarrow_forwardIs it realistic to expect a doctor's office or hospital to back their work with a guarantee? Explain .arrow_forwardWhich of the following types of fat is required to be listed on the Nutrition Facts Panel by the U.S Food and Drug Administration? A. Trans fatty acids B. Essential fatty acids C. Phospholipids D. Sterolsarrow_forward
- What is the meaning of the term "Calories" written on food packaging? By convention, one Calorie (C), with a capital C, that is used for food is equal to one kilocalorie. On your Activity Sheet, paste a label or cut-out portion from food packaging indicating the number of Calories. (If you have no packaging at home, you may invent and draw your own label.) Convert these Calories into kilocalories and calories.arrow_forwardThe food label in Figure 11.28 lists the nutrients and other substances in a package of ready-to-eat macaroni and cheese. Based on your reading in this chapter, how would you rate this products healthiness in terms of fats and carbohydrates? Figure 11.28 Food labels are useful health tools. Information on a food label can be used to ensure that you get the nutrients you need without exceeding recommended limits on less healthy substances such as salt, sugar, and trans fats. At present, the USDA is considering major revisions to food labels. The proposed changes include showing realistic serving sizes and sugars added by the manufacturer, and printing the calorie content per serving in larger, bolder type so that it is easier for consumers to make informed choices about purchases of prepared foods.

Can you help me to explain to me, please?arrow_forward
