CBSE Class 6 Science Notes Chapter 2 Components of Food

• Energy giving food: Carbohydrates and fats.
• Bodybuilding food: Proteins.
• Protective food: Vitamins and minerals.

CBSE Class 10 Science Sample Paper 2023-24

Carbohydrates

• Foods like rice, wheat, sorghum, peas, beans, sago (sabudana), sugarcane, sugar beet, along with fruits such as banana, mango, and melons, as well as vegetables, provide us with carbohydrates.
• Cellulose, starch, sucrose, glucose, and fructose are key carbohydrates in our diet.
• Starch causes iodine solution to change to a dark blue or black colour.

Fats

• Fats can come from either plants or animals. Examples of plant-derived fats include groundnut oil, soybean oil, and mustard oil, while animal-derived fats include butter and ghee.
• Fats serve as fuel in our bodies, offering more energy compared to carbohydrates. In small amounts, fat deposits provide advantages for our body, aiding in organ growth, protection from injury, and prevention of heat loss from the body surface.
• However, excessive fat deposition is detrimental to health, leading to obesity. Fatty substances leave greasy and transparent spots on paper.

Proteins

• Milk, fish, meat, cheese, and eggs are the primary sources of animal proteins. Plant proteins can be found in legumes like beans and lentils.
• Proteins are necessary for the growth and repair of our bodies. They aid in constructing new tissues and contribute to the strength of hair and nails, as well as the structure of muscles. They are also essential components of our blood, facilitating proper bodily functions.
• During periods requiring rapid tissue growth, such as infancy, pregnancy, or when a mother is breastfeeding, a significant amount of protein is necessary.

Vitamins

Minerals

Water

• Our body needs a good amount (around 5-7 litres) of water every day.
• Water helps our body do various things like aiding digestion, getting rid of waste through urine, and purifying the blood.
• It also helps keep our body cool by sweating and promotes blood circulation.

Roughage

• Whole grains, flour, cereals, potatoes, fresh food, raw, and cooked vegetables contribute fibre to our meals.
• This aids in the digestion process and avoids constipation.

Some Diseases or Disorders Caused by deficiency of Vitamins and Minerals

Balanced Diet

• Milk group: includes milk and milk products
• Meat group: includes meat (chicken, fish, lamb, etc.) and meat substitutes (beans, peas, nuts, and seeds)
