Consider the following statements regarding the factors affecting glycemic index:
- If the amount of fiber in a food is high, the glycemic index can be reduced.
- If the food is processed further, its glycemic index can be increased.
- Fat in food always speeds up the absorption of glucose.
Which of the above statements are correct?
Correct answer: A
Explanation
Statement 1 is right: higher fibre slows digestion and lowers the glycemic index. Statement 2 is right too, since heavier processing breaks down food structure and pushes the glycemic index up. Statement 3 is wrong because fat tends to slow gastric emptying and glucose absorption rather than speed it up.
