Answer 1

Basis of Difference	Simple Carbohydrate	Complex Carbohydrate
1. Meaning	Simple carbohydrates are carbohydrates made up of one or two sugar units.	Complex carbohydrates are carbohydrates made up of many sugar units linked together.
2. Chemical structure	Simple carbohydrates are monosaccharides or disaccharides, composed of a single sugar unit or two monosaccharides combined.	Complex carbohydrates are polysaccharides, composed of many monosaccharide units linked together.
3. Examples	Simple carbohydrates include glucose, fructose, galactose, sucrose, lactose and maltose.	Complex carbohydrates include starch, glycogen and cellulose (fibre).
4. Digestion and absorption	Simple carbohydrates are rapidly absorbed by the body and provide quick energy.	Complex carbohydrates are digested more slowly and provide sustained energy.
5. Food sources	Simple carbohydrates are found in fruits, honey, sugarcane, milk and malted foods.	Complex carbohydrates are found in cereals, rice, wheat, oats, potatoes, legumes and corn.
6. Effect on health	Simple carbohydrates can raise blood sugar quickly, so refined simple sugars should be limited.	Complex carbohydrates provide fibre and are healthier as they give long-lasting energy.
