Carbohydrate's role in body
Carbohydrate's role in body
Carbohydrates provide energy to the body and are a key fuel source for blood and the nervous system.
Simple Carbohydrates
Simple Carbohydrates
Simple carbohydrates are sugars like glucose, fructose, and lactose found in foods like fruits, honey, and milk.
Complex Carbohydrates
Complex Carbohydrates

Study Notes
Carbohydrates
- Carbohydrates are the body's primary energy source, particularly for the brain and nervous system.
- They are composed of carbon, hydrogen, and oxygen.
- Carbohydrates are the most abundant dietary energy source, making up 50-70% of intake.
- Carbohydrates provide 4 kcal/g of energy.
Types of Carbohydrates
- Simple carbohydrates include naturally occurring sugars (glucose, fructose, sucrose, lactose) and added sugars (honey, corn syrup, sugar).
- Complex carbohydrates include starches (cereals, millets, pulses, root vegetables) and glycogen (animal foods). Cellulose in vegetables is resistant to digestion.
Importance of Carbohydrates
- Normal blood glucose levels are essential for well-being and energy.
- Low blood glucose levels lead to weakness and shakiness.
- High blood glucose levels cause sleepiness.
- Maintaining blood glucose levels requires conscious effort.
Alternative Energy Sources
- Fats and Proteins are also energy sources, but less efficient for the brain and nerves, as well as potentially associated with diseases.
