Raman’s statement is accurate; starches are a type of carbohydrate, but not all carbohydrates are starches. Simple sugars and fiber are also carbohydrates. Testing can involve identifying different carbohydrates in common foods using iodine solution.
What do you think of Raman’s statement, All starches are carbohydrates but not all carbohydrates are starches. Describe the design of an activity to test your answer.

Raman’s statement highlights an important distinction in nutrition. Starches are polysaccharides, a form of carbohydrate, while carbohydrates also include simple sugars and fibers. To test this, we can design a simple activity using common foods.
Activity Design:
1. Materials Needed: Iodine solution, various food samples (potatoes, rice, bread, fruits, vegetables, and sugar), test tubes, and a dropper.
2. Procedure:
– Label the test tubes with the names of each food sample.
– Place small pieces of each food item into separate test tubes.
– Add a few drops of iodine solution to each sample.
– Observe color changes: a blue-black color indicates the presence of starch, while no change indicates the absence of starch.
3. Observation: Record which foods contain starch (e.g., potatoes, rice) and which do not (e.g., fruits, sugar).
This activity demonstrates that while starches are carbohydrates, other carbohydrates exist that are not starches, supporting Raman’s statement.
