FAQs on PPT: Food, Nutrition, Health & Diseases
| 1. What are the main nutrients my body needs and why does each one matter? |  |
Ans. The body needs carbohydrates for energy, proteins for growth and repair, fats for insulation and hormone production, vitamins for immunity and disease prevention, minerals for bone strength and metabolism, and water for all bodily functions. Each nutrient plays a specific role in keeping students healthy, active, and able to concentrate during school and studies.
| 2. How can I tell the difference between a balanced diet and junk food for Class 5 health? | |
Ans. A balanced diet includes all nutrient groups-grains, proteins, vegetables, fruits, and dairy-in proper proportions, while junk food is high in sugar, salt, and unhealthy fats but low in nutritional value. Balanced meals give sustained energy and protect against diseases; junk food causes weight gain, tooth decay, and poor concentration in studies.
| 3. What's the connection between eating healthy food and getting sick less often? | |
Ans. Nutritious food strengthens the immune system by providing vitamins, minerals, and antioxidants that fight germs and infections. Students who eat balanced meals with fresh vegetables, fruits, whole grains, and proteins build resistance to common diseases like colds, coughs, and infections, staying healthier and missing fewer school days.
| 4. Why do some foods cause health problems even though they taste good? | |
Ans. Foods high in sugar, salt, and trans fats taste good because they trigger pleasure in the brain, but they lead to obesity, diabetes, high blood pressure, and heart disease over time. The immediate satisfaction doesn't match long-term health consequences, making nutrition education crucial for making informed food choices early.
| 5. How should I plan my meals to stay fit and healthy for exams and daily activities? | |
Ans. A healthy meal plan includes breakfast with whole grains and protein, lunch with vegetables and lean meat, snacks with fruits or nuts, and dinner with balanced portions. Drinking adequate water, limiting sugary drinks, and eating at regular intervals maintain energy levels, improve focus during study sessions, and support overall wellness for academic performance.
