Millets are highly nutritious grains rich in essential nutrients.

Our body requires a variety of food items to stay healthy, energetic, and strong. Foods are classified into three main groups:

• Energy-giving foods: Rich in carbohydrates and fats. Provide energy to our body. Examples: Rice, potato, wheat, maize, banana, apple, sweet potato, honey, millets, butter, ghee, and oil.
• Body-building foods: Rich in proteins. Help us grow, build muscles, and make us strong. Examples: Pulses, legumes, soybeans, chickpeas, peanuts, tofu, milk, cheese, beans, almonds, walnuts, eggs, meat, and fish.
• Protective foods: Rich in vitamins and minerals. Help us fight against and protect us from diseases. Examples: Fruits and vegetables like carrot, orange, lemon, papaya, spinach, cabbage, guava, amla, and tomato.

• Balanced Food Plate: A plate containing the right quantities of food from all three food groups, with protective foods (fruits and vegetables) making up the largest portion, followed by body-building and energy-providing foods.
• Junk Food: Foods containing high amounts of oil, salt, and sugar that are unhealthy if consumed regularly. Examples: Soft drinks, chips, bread pakoda, burgers, and pizza. Fresh home-cooked food is always preferred over packaged food.

Water is a vital part of our diet with several key functions:

• Helps in digesting food.
• Keeps skin and body healthy.
• Removes waste from the body through urine, sweat, and faeces.
• Can be sourced from drinking water and water-rich fruits like watermelon and cucumber.

Different food items require different preparation methods to be palatable and healthy:

• Steaming: e.g., Idli, Idiyappam
• Boiling: e.g., Rice, Kheer, Sambhar
• Frying: e.g., Samosa, Puri
• Roasting: e.g., Papad
• Baking: e.g., Cake, Muffins
• Grilling: e.g., Roasted corn
• Solar Cooker: An eco-friendly cooking method that uses sunlight instead of fire or electricity, producing no smoke or ash.
