### Lesson Notes on Carbohydrates
**Objective:**
By the end of this session, students will understand the structure, function, types, and significance of carbohydrates in our diet.
---
### Introduction to Carbohydrates (2 minutes)
- **Definition**: Carbohydrates are organic compounds made up of carbon, hydrogen, and oxygen. They are one of the primary macronutrients, alongside proteins and fats.
- **Role in Diet**: Carbs are the body's main source of energy, essential for proper functioning and physical activity.
---
### Structure of Carbohydrates (3 minutes)
1. **Basic Unit**: The monosaccharide is the simplest form of carbohydrates (e.g., glucose, fructose).
- **Monosaccharides**: Single sugar molecules.
- **Examples**: Glucose (found in blood), Fructose (found in fruits).
2. **Disaccharides**: Formed when two monosaccharides join.
- **Examples**:
- Sucrose (glucose + fructose, common table sugar)
- Lactose (glucose + galactose, found in milk).
3. **Polysaccharides**: Long chains of monosaccharides.
- **Examples**:
- Starch (storage form of energy in plants)
- Glycogen (storage form of energy in animals)
- Cellulose (structural component of plant cell walls).

### Types of Carbohydrates (4 minutes)
1. **Simple Carbohydrates**:
- Composed of one or two sugar molecules.
- Found in fruits, milk, and sugary foods.
- **Quick Energy Source**: Digested rapidly, can lead to energy spikes.
2. **Complex Carbohydrates**:
- Composed of long chains of sugar molecules.
- Found in whole grains, legumes, and vegetables.
- **Steady Energy Source**: Digested slowly, providing sustained energy.
3. **Fiber**:
- A type of complex carbohydrate that the body cannot digest.
- **Types**:
- Soluble Fiber: Dissolves in water and slows digestion (e.g., oats, apples).
- Insoluble Fiber: Does not dissolve and promotes regularity (e.g., whole grains, nuts).
- **Benefits**: Aids digestion, helps control blood sugar levels, and lowers cholesterol.
---
### Functions of Carbohydrates (4 minutes)
- **Energy Production**: Carbs are broken down into glucose, which is then used by cells for energy.
- **Brain Function**: The brain relies on glucose as its primary energy source.
- **Spare Protein**: Amino acids from proteins can be used for energy, but carbs help spare protein for its main functions (e.g., tissue repair).
- **Fat Metabolism**: Carbs are necessary for the oxidation of fats.
---
### Health Aspects and Recommendations (4 minutes)
- **Recommended Daily Allowance (RDA)**: Carbohydrates should make up 45-65% of total daily calorie intake.
- **Choosing Healthy Carbs**:
- Opt for whole grains over refined grains.
- Incorporate fruits and vegetables for fiber and nutrients.
- Limit added sugars from processed foods.
- **Negative Impacts**: Overconsumption of simple sugars can lead to obesity, type 2 diabetes, and heart disease.
---
### Conclusion and Q&A (3 minutes)
- **Key Takeaways**:
- Carbohydrates are essential for energy and overall health.
- Focus on consuming more complex carbohydrates and fiber-rich foods.
- **Q&A Session**: Encourage students to ask questions about carbohydrates, share their thoughts on dietary choices, or discuss any confusion they have about carbs.
---
### Interactive Activity (Optional)
If time allows, consider a quick activity where students categorize foods into simple or complex carbohydrates to reinforce learning and engagement.
