Mindful Eating: A Path to a Healthy Body — NCERT Solutions, AI Tutor & Practice

Understand: A balanced diet is a diet that contains all the required nutrients — carbohydrates, proteins, fats, vitamins, minerals — along with dietary fibre and water, in the correct proportions.

Analyze: Each nutrient does a different job:

• Carbohydrates and fats give energy.
• Proteins help in growth and repair.
• Vitamins and minerals protect the body from diseases.
• Fibre and water keep digestion healthy.

Conclude: A balanced diet is important because it supplies the body with everything it needs to grow, stay active, and fight illness. Missing even one component can cause health problems.

The main nutrients and their functions:

| Nutrient | Main Function | |----------|---------------| | Carbohydrates | Provide energy | | Fats | Provide energy (more than carbohydrates) | | Proteins | Help in growth and repair of the body (body-building) | | Vitamins | Protect the body from diseases | | Minerals | Keep the body healthy (e.g., calcium for bones) |

Besides these, dietary fibre helps in the movement of food and water helps in digestion and removing wastes.

Test for Starch (Iodine Test):

1. Take a small quantity of the food item to be tested.
2. Add 2–3 drops of dilute iodine solution on it.
3. Observation: If the food turns blue-black in colour, it contains starch (a carbohydrate).
4. If there is no colour change, starch is absent.

Example: Putting iodine on boiled rice or potato turns it blue-black, showing they are rich in starch.

Test for Proteins:

1. Take a small amount of the food item; if it is solid, grind it and make a paste with a little water.
2. Add 2 drops of copper sulphate solution.
3. Then add 10 drops of caustic soda (sodium hydroxide) solution.
4. Shake well and leave for a few minutes.
5. Observation: If the mixture turns violet (purple), the food contains protein.

Example: Foods like pulses (dal), eggs, and milk give a violet colour, showing they are rich in proteins.

Test for Fats:

1. Take a small quantity of the food item and wrap it in a piece of paper.
2. Crush the food so that it presses against the paper.
3. Straighten the paper and let it dry for some time.
4. Hold the paper up towards light.
5. Observation: An oily patch on the paper that light passes through (translucent patch) shows that the food contains fat.

Example: Groundnuts, butter, and ghee leave clear oily patches on paper.

Understand:

• Roughage (dietary fibre) is the fibrous part of plant foods that our body cannot digest.
• Water is essential for all body processes.

Analyze:

• Roughage does not provide energy, but it helps the body get rid of undigested food and prevents constipation.
• Water helps in digestion of food, absorption of nutrients, and removal of wastes from the body.

Conclude: Even though roughage and water do not supply energy, they are essential parts of a balanced diet because they keep the digestive system working smoothly and healthy.

Sources of roughage: whole grains, fresh fruits, vegetables, and pulses.

Understand: Deficiency diseases are illnesses that occur when a person does not get enough of one or more nutrients over a long period of time.

Examples:

| Disease | Deficient Nutrient | |---------|-------------------| | Scurvy (bleeding gums, weakness) | Vitamin C | | Rickets (weak, bent bones) | Vitamin D / Calcium | | Night blindness | Vitamin A | | Anaemia (weakness, pale skin) | Iron (a mineral) | | Goitre (swelling of neck) | Iodine (a mineral) |

Conclude: Deficiency diseases can be prevented by eating a balanced diet that contains all the nutrients in proper amounts.

Understand: Mindful eating means paying full attention to what and how we eat — choosing healthy food, eating slowly, and being aware of the taste, smell, and quantity of food.

Habits for mindful eating:

1. Eating slowly and chewing food properly instead of hurrying.
2. Avoiding distractions like watching TV or mobile phones while eating.
3. Eating only when hungry and stopping when full (not overeating).
4. Choosing fresh, home-cooked, balanced meals over junk food.

Conclude: Mindful eating helps digestion, prevents overeating, and keeps the body healthy — which is why it is 'a path to a healthy body'.

Understand: A balanced meal must contain all nutrients. Let us look at each food item:

Analyze:

• Rice / Roti → rich in carbohydrates → provide energy.
• Dal (pulses) → rich in proteins → help in growth and repair.
• Vegetables → rich in vitamins, minerals and fibre → protect the body and aid digestion.
• Curd → provides proteins, calcium and fats → helps in body-building and bone strength.
• A little ghee/oil → provides fats for extra energy.
• Water taken with the meal helps in digestion.

Conclude: Since this meal together supplies carbohydrates, proteins, fats, vitamins, minerals, fibre and water, it is a balanced diet. This shows how traditional Indian food combinations are naturally nutritious.

Interpreting each result:

• (a) Sample P → blue-black with iodine → contains starch (carbohydrate).
• (b) Sample Q → oily patch on paper → contains fat.
• (c) Sample R → violet with copper sulphate + caustic soda → contains protein.
• (d) Sample S → blue-black with iodine (starch) and oily patch (fat) → contains both carbohydrate and fat.

Conclusion: A single food item can contain more than one nutrient, as shown by Sample S. This is why we must perform different tests to find all nutrients present.

Understand: Good health depends on eating the right amount of a balanced diet — neither too little nor too much.

Analyze:

• Undernutrition (eating too little / lacking nutrients):

  • The body does not get enough energy and nutrients.
  • This causes weakness, poor growth, and deficiency diseases like anaemia or scurvy.

• Overeating (eating too much, especially fatty/sugary food):

  • The body stores extra food as fat.
  • This can cause obesity and related health problems.

Conclude: Both extremes harm the body. Therefore, mindful eating — taking a balanced diet in the correct quantity — is the healthy path.

Habits to avoid food wastage:

1. Take only as much food as you can eat on your plate; take more later if still hungry.
2. Store leftover food properly and use it in the next meal instead of throwing it away.
3. Plan and cook the right quantity of food according to the number of people eating.
4. Share extra food with others who need it, instead of wasting it.

Conclude: Avoiding food wastage is part of mindful eating. It shows respect for food and for the effort and resources used to produce it, and it helps ensure food is available for everyone.
