Question

based on the article, how are the foods people eat linked to changes in blood sugar?
a food takes sugar out of the blood, so walking after eating can cause blood sugar levels to drop too low.
b food stops sugar from entering the blood, which prevents blood sugar from changing after meals.
c food adds sugar to the blood, and walking after eating can help keep that sugar from rising too quickly.
d food only affects blood sugar during exercise, so levels stay the same unless someone walks after eating.

Explanation:

To determine the correct answer, we analyze each option based on basic physiological knowledge about food and blood sugar:

• Option A: Food does not take sugar out of the blood; rather, digestion breaks down food (especially carbohydrates) into sugar that enters the blood. So this is incorrect.
• Option B: Food (especially carbohydrates) is broken down into sugar which enters the blood, so food does not stop sugar from entering the blood. This is incorrect.
• Option C: When we eat, food (particularly carbohydrate - rich foods) is digested and the sugar from it is absorbed into the bloodstream, increasing blood sugar. Walking (exercise) after eating can help the body use that sugar, preventing it from rising too quickly. This matches our understanding of how food and exercise affect blood sugar.
• Option D: Food affects blood sugar even without exercise; digestion of food leads to sugar entering the blood. So this is incorrect.

Answer:

C. Food adds sugar to the blood, and walking after eating can help keep that sugar from rising too quickly.
