🔑Concepts
A Balanced Diet is a diet that contains the right proportions of carbohydrates, proteins, fats, vitamins, minerals, (water), and roughage required for the healthy growth and maintenance of our body.
Nutrients are categorized into three main groups: Energy-giving foods (Carbohydrates and Fats), Body-building foods (Proteins), and Protective foods (Vitamins and Minerals).
Carbohydrates are the main source of energy for our body. Common examples include starch and sugar.
Proteins are essential for the growth and repair of worn-out tissues in our body.
Vitamins like Vitamin , -complex, , , , and are needed in small quantities to protect the body against diseases.
Roughage is the fibrous content in our food (like salads and whole grains) that helps in the easy passage of stools and prevents constipation.
Water () helps in the digestion of food, absorption of nutrients, and maintains the body temperature through .
Food preservation methods include boiling, salting, sweetening (adding sugar), dehydration (drying), and refrigeration to prevent the growth of microbes.
