Question

Arrange the following food items in increasing order of their Glycemic Index (low GI to high GI).
A. Popcorn
B. Apple
C. Whole Wheat Bread
D. Soybean
E. Rice Porridge
Select the correct answer from the options given below

• A. B, C, D, A, E
• B. D, B, A, C, E
• C. C, E, B, A, D
• D. A, C, E, D, B

Hint:

Glycemic Index sequence: Soybean (15) $<$ Apple (36) $<$ Popcorn (60) $<$ Whole wheat bread (70) $<$ Rice porridge (80+).

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
The Glycemic Index (GI) ranks carbohydrate foods from 0 to 100 based on their relative blood glucose response compared to pure glucose or white bread.
Key Formula or Approach:
\[ \text{Low GI: } \le 55 \quad | \quad \text{Medium GI: } 56 - 69 \quad | \quad \text{High GI: } \ge 70 \]

Step 2: Detailed Explanation:
Evaluating the typical Glycemic Index (GI) values of the given foods:
1. D. Soybean (Legume): Very Low GI ($\approx 15 - 18$) due to high protein, fiber, and resistant starch.
2. B. Apple (Fresh Fruit): Low GI ($\approx 36 - 38$) rich in soluble pectin and fructose.
3. A. Popcorn (Whole Grain Snack): Moderate GI ($\approx 55 - 65$).
4. C. Whole Wheat Bread: High GI ($\approx 69 - 72$).
5. E. Rice Porridge (Congee Overcooked White Rice): Very High GI ($\approx 78 - 85$) due to rapid starch gelatinization.
Arranging in increasing order (low to high): D $\rightarrow$ B $\rightarrow$ A $\rightarrow$ C $\rightarrow$ E.

Step 3: Final Answer:
Therefore, the correct ascending order is D, B, A, C, E, matching option (B).
