Which statement about carbohydrates is correct?

Question

BlackTom AI · Accepted Answer

When evaluating this question about carbohydrates, it helps to test each statement against established nutrition concepts.
Option 1: 'Carbohydrates are only found in sugary snacks.' This is incorrect because carbohydrates are present in a wide variety of foods beyond sweets, including fruits, vegetables, grains, legumes, and dairy products, not just sugary snacks.
Option 2: 'Simple carbohydrates are found in whole grains.' This is inaccurate. Whole grains primarily contain complex carbohydrates, along with fiber and other nutrients. Simple carbohydrates are typically found in foods with added sugars or refined products, not in whole grains.
Option 3: 'Complex carbohydrates include starches and fiber.' This statement aligns with nutrition science: complex carbohydrates comprise longer chains of sugar units, including starches found in grains and legumes, as well as dietary fiber from plant sources. These components contribute to digestion and health in different ways.
Option 4: 'The Dietary Guidelines recommend less than 10% of daily calories come from carbs.' This is not consistent with dietary guidelines, which generally recommend that carbohydrates supply about 45–65% of daily calories, with emphasis on choosing complex, high-fiber sources.
Overall, the third option accurately reflects how complex carbohydrates are defined and what they include, while the others misstate the scope, sources, or official recommendations related to carbohydrate intake.
