  2.    Proteins
  3.    Fats
  4.    Minerals
 Discuss Question
Answer: Option B. -> Proteins
:
B

  • Proteins are required for the growth and repair of our body. They are also called body-building foods.

  • Carbohydrates provide the major source of energy forour daily activities.

  • Fats arethe major storage form of energy in the body.

  • The body uses minerals to perform many different functions like building strong bones.

Question 2. Food provides us with a lot of components that are needed by our body. These components are called _________ .
  1.    spices
  2.    fibres
  3.    nutrients
  4.    muscles
 Discuss Question
Answer: Option C. -> nutrients
:
C
Food provides us with essential components needed by our body. These components are called nutrients. The six essential nutrients are carbohydrates, proteins, fats, vitamins and minerals.
Question 3. A food sample is rubbed on a piece of paper and the paper becomes translucent. This indicates the presence of _______.
  1.    carbohydrates
  2.    proteins
  3.    fats
  4.    vitamins
 Discuss Question
Answer: Option C. -> fats
:
C
When a food sample is rubbed on a piece of paper and if the paper becomes translucent and remains so even after it dries. This indicates the presence of fats in that food. Oils and cheese arerich sources of fat.

Question 4. What is PEM? Mention and describe two examples. [3 MARKS]
 Discuss Question

:
Definition: 1 Mark
Examples: 1 Mark each
PEM stands for Protein Energy Malnutrition.Lack of proteins in the diet results in the development of diseases related to PEM. Kwashiorkor and Marasmus are two types of diseases related with protein energy malnutrition.
1. Kwashiorkor is a disease that predominantly affects children under five years of age, if they do not get enough protein in their regular diet.
2. Marasmus is a disease that affects mostly infants who feed on mother's milk which is poor in protein content.
Question 5. What is the procedure for testing a food item for fat content? [5 MARKS]
 Discuss Question

:
1 Mark each
The following steps are performed to test the presence of fat in a food item.
1. A small quantity of the food item to be tested is taken.
2. The food item is wrappedin a small piece of paper, and the paper is crushed.
3. The paper is straightened
4. The paper is then dried in sunlight for a while
5. An oily patch on the paper indicates the presence of fat in the tested food item.
Question 6. Explain any 5 constituents of our food in detail. [5 MARKS]
 Discuss Question

:
1 Mark each
Any five:
The components present in our food are:- carbohydrates, fats, proteins, vitamins, minerals, water and fiber.
1.Carbohydratesare made of carbon, hydrogen and oxygen molecules. Sugars, starch and cellulose are examples of carbohydrates.Starch and cellulose are broken down in the body into simple sugars like glucose.They provide instant energy.Carbohydrates are present in rice, wheat, jowar, maize and other grains.They are also present in tubers and fruits.
2. Proteinsare formed by carbon, hydrogen, oxygen and nitrogen. Nitrogen is the most essential element in proteins, but some proteins contain sulphur and phosphorus also. They form simple molecules called amino acids on digestion. Proteins act as building blocks and serve as materials helping in growth and repair of the body cells and tissues. They also help in the formation of hair and nails. Foods rich in proteins include lean meat, fish, eggs, milk, cheese, nuts, beans and peas.
3. Fatsare also made up of carbon, hydrogen and oxygen. They have very little oxygen content and produce more energy than carbohydrates do. Fat below the skin protects the body against rapid loss of heat. It serves as a solvent for fat-soluble vitamins. It is an important form of energy storage for future use. Common food rich in fats includes milk, cheese, butter, cream, ghee, vegetable oils, meat and fish liver oils.
4. Vitaminsare the chemical substances that help in maintaining a healthy body. Vitamins A, D, E, and K are fat soluble and can be stored in the body. Vitamin B complexes and Vitamin C are water soluble forms. They cannot be stored for a long period of time in the body.
5. Mineralsare needed in the diet in small quantities. These are obtained from table salt, green vegetables, and fruits.
6. Wateris an important component which helps the body absorb the nutrients from the food. It also helps the body to get rid of toxic wastes through urine and sweat. It provides the medium for transportation of substances in the body.
7.Dietary fibresare necessary for the smooth movement of food in the alimentary canal. They provide bulk roughage to remove the undigested waste during defecation.
Question 7. Which among the following nutrient is present in energy giving foods?
  1.    Carbohydrates
  2.    Minerals
  3.    Vitamins
  4.    Fibres
 Discuss Question
Answer: Option A. -> Carbohydrates
:
A
Foods containing carbohydrates and fats are called energy giving foods. They provide energy to our body for performing various functions.
Question 8. Identify the disease caused by the deficiency of Vitamin D in children.
  1.    Goitre
  2.    Scurvy
  3.    Beri Beri
  4.    Rickets
 Discuss Question
Answer: Option D. -> Rickets
:
D
Vitamins are nutrients that are required by the body in very small quantities. Vitamin D is important for healthy bones and teeth. If the body does not get sufficient amount of vitamin D, it leads to a deficiency disease called rickets in children. Itresults insoftening and weakening of bones. In adults, deficiency of vitamin D causes another disease called osteomalacia.

Question 9. A balanced diet must contain:
  1.    More of vitamins and minerals
  2.    More of carbohydrates
  3.    More of proteins
  4.    All nutrients in right quantity
 Discuss Question
Answer: Option D. -> All nutrients in right quantity
:
D
A diet that contains all the nutrients required by our body in right quantity is called balanced diet. A balanced diet contains carbohydrates, fats, proteins, vitamins, minerals, roughage and water in required amounts.
Question 10. Excess intake of fat-rich food on a daily basis without any physical activity will result in __________.
  1.    obesity
  2.    scurvy
  3.    beriberi
  4.    rickets
 Discuss Question
Answer: Option A. -> obesity
:
A
Obesity is a condition caused by excess intake of energy rich food like fats and carbohydrates without sufficient physical activity. The body stores all the excess fats and deposits them in different parts of the body. This is called obesity.
