Question 4.
Our food habits also change when the living facilities improve. Such changes are illustrated in the picture above. Observe the picture and discuss the changes.
Answer:
| Food Then |
Food Now |
| People ate simple, homemade, fresh food. |
Many people eat fast food, packed snacks, and soft drinks. |

These items have more fat, sugar, and oil. |
| The food had more nutrients and fewer artificial substances. |
They contain preservatives, flavours, and colours. |
| Cooking was done at home, so food was cleaner and healthier. |
Although convenient, these foods are less nutritious. |
Question 5.
Are these changes healthy? Shouldn’t we plan our food by including diverse food items to get all essential nutrients?
Answer:
No, Fast foods and packaged foods are not healthy. They may cause obesity, diabetes, stomach problems, and weakness. So, we must choose food items that provide all essential nutrients, such as proteins, vitamins, minerals, fats, and carbohydrates.
Question 6.

Question 7.
(a) Did you notice the conversation?
Answer:
Yes
(b) Do you agree with what the child said?
Answer:
No, it is not a healthy choice to eat only bread and jam every day. While it may taste good, it does not give the body all the nutrients it needs.
(c) Why do our parents include locally available eggs, milk, fruits, vegetables and leafy vegetables in our diet?
Answer:
These foods are rich in essential nutrients.
Eggs and milk provide protein, calcium, vitamins, and minerals that support growth and strong bones. Vegetables, fruits and leafy vegetables give vitamins, minerals and fibre needed to keep us healthy and protect us from diseases.
Question 8.
What were our food items and food habits in the past?
Answer:
In the past, people ate fresh and natural foods from their own fields and gardens. They had traditional dishes like pazhamkanji, thoran, and homemade snacks. Their meals included rice, vegetables, fruits and leafy greens. Food was cooked at home, and they rarely bought anything from shops. Their diet was simple, healthy and nutritious.
Have a look at Ammu’s grandma’s food habits.
Grandma’s Food Habits.
In the past, Grandma lived in a joint family where everyone cooked and ate together. They enjoyed fresh, homemade foods like kappapuzhukku, chakrapuzhukku and pazhamkanji for breakfast. Lunch was parboiled rice with vegetables, jackfruit, banana stem and delicious fish curry. In the evenings, they had steamed snacks like kozhukkatta or ada. They also ate many fresh fruits such as mangoes, bananas and guavas. Their food was simple, natural and very healthy.
Question 9.

(b) What changes have taken place in your daily diet? Discuss and prepare a note.
Answer:
Many changes have occurred in my daily diet. Earlier, families ate fresh, natural foods grown at home, such as rice, vegetables, leafy greens, jackfruit, bananas, and homemade snacks. But now, I eat more processed foods such as noodles, chips, chocolates, bakery items and foods bought from shops. Because of this, my diet today is different from the simple and healthy food my grandma ate.
(c) Check whether all these changes in the food habits are good for health?
Answer:
All these changes are not good for health. Traditional foods were fresh, nutritious and made at home. They helped keep people strong and healthy. Modern processed foods often contain more sugar, salt, oil and chemicals. Eating them too often can cause health problems. So, it is better to include more homemade and traditional foods in our diet for good health.
As living conditions improved, food habits changed. These changes are not good for a healthy life. Menu should be balanced to ensure the intake of all nutrients by including diverse food items.

Question 16.
(a) Does eating more food lead to better health?
Answer:
No
(b) Let’s find out whether these two children have proper growth. How do we find out?
Answer:
One of the methods to check growth is ‘Body Mass Index’ (BMI). It can be used to find out whether a person has a weight proportionate to their height. For this, height and weight should be found out first. Body Mass Index is weight in kilograms divided by (height in metres x height in metres)
(c) The first child has 25 kg weight and 120 cm height. What is his BMI?
Answer:
BMI = \(\frac{\text { Weight }(\mathrm{kg})}{\text { Height (metre) } \text { × } \text { Height (metre) }}\)
BMI = \(\frac{25}{1.20 \times 1.20}\) = 17.36
(d) The second child has 45 kg weight and 125 cm height. What is his BMI? Find out using the formula to calculate BMI.
Answer:
BMI = \(\frac{\text { Weight }(\mathrm{kg})}{\text { Height (metre) } \text { × } \text { Height (metre) }}\)
BMI = \(\frac{45}{1.25 \times 1.25}\) = 28.8
BMI Chart:
(e) What are your inferences?
Answer:
Physical condition of the first child:
BMI = 17.36
According to the BMI chart, below 18.5 = Underweight
The first child is Underweight.
Physical condition of the second child:
BMI = 28.8
According to the BMI chart, 25-29.9 = Overweight
The second child is Overweight.
(f) What is the reason for this kind of physical condition in these two children? Discuss.
Answer:
Reasons for the first child being underweight:
- Not eating enough nutritious food.
- Skipping meals or having an unbalanced diet.
- More physical activity but less calorie intake.
- Eating less protein, vitamins, and minerals.
Reasons for the second child being overweight:
- Eating more junk food, fast food, and oily items.

Question 25.
Excessive mobile phone use can lead to many health issues. Organise a debate on the topic ‘Excessive Use of Mobile Phones and Health Issues.’
Answer:
Topic: Excessive Use of Mobile Phones and Health Problems.
Team 1: Mobile Phones Cause Health Problems.
- Mobile phones are useful, but using them too much can harm our health.
- They can cause eye strain, headaches, poor sleep, and neck pain.
- Children spend too much time on games and videos, which leads to stress and less concentration.
- So, excessive use of mobile phones is bad for our health.
Team 2: Mobile Phones Are Helpful When Used Properly.
- Mobile phones are not always harmful.
- They help students learn new things, stay connected, and even improve safety.
- Health problems happen only when we overuse them.
If we take breaks and use phones wisely, they become very useful tools.

CHOLESTEROL
- A total cholesterol level below 200 mg/dL is the ideal condition.
- There are two types of cholesterol, good cholesterol (HDL) and bad cholesterol (LDL).
- Excess bad cholesterol accumulates in blood vessels and blocks blood flow, leading to a heart attack.
- It also harms the liver. As good cholesterol levels increase, the risk of a heart attack decreases.
- Good cholesterol levels increase in the body during exercise.
- Similarly, fish like sardines and mackerel, and food items like leafy vegetables, pulses, groundnuts, walnuts, etc., help raise the level of good cholesterol.
