- A high-fibre diet supports weight maintenance.
Balanced Diet
- A balanced diet includes essential nutrients: carbohydrates, fats, proteins, vitamins, minerals, roughage, and ample water.
- It is essential for overall health and fitness.
Reducing Food Wastage
- Overbuying leads to spoilage; only buy needed amounts.
- Cooking in smaller quantities helps avoid leftovers.
- Store perishable items in the refrigerator to reduce spoilage.
- Take smaller portions to minimize uneaten food.
Essential Minerals
- Key minerals include calcium, iron, potassium, manganese, copper, iodine, and zinc.
- Calcium strengthens bones and teeth; found in dairy and leafy greens.
- Iron aids oxygen transport; sources include red meat, lentils, and green veggies.
- Potassium regulates muscle and nerve functions; found in bananas and potatoes.
Importance of Water
- Water constitutes over half of body weight and is essential for all bodily functions.
- It aids digestion, nutrient absorption, and waste elimination.
- Drinking 6-8 glasses of water daily is recommended.
Carbohydrates
