Question

Quizplus · Accepted Answer

TEF (thermic effect of food) refers to the amount of energy required by the body to digest and absorb the nutrients in food. The TEF for carbohydrates, which make up the majority of a plain bagel, is around 10%. Therefore, the approximate TEF for a 260-calorie plain bagel would be 26 calories (260 x 0.1 = 26). Choice C is the closest option to this calculation. Choices A, B, and D are too high or too low to be reasonable estimates.
