Question 2. Discuss traditional versus modern culinary practices in India.

Answer:

Traditional culinary practices involved cooking food on clay stoves (chulhas) using firewood or cow dung cakes and grinding grains or spices with a sil-batta. These methods required more time and manual effort.

Modern culinary practices use LPG stoves, induction cooktops, microwave ovens, pressure cookers and mixer grinders. These methods save time, reduce physical effort, improve hygiene and make cooking faster and more convenient. However, many traditional cooking methods are still valued because they help preserve the authentic taste and cultural heritage of Indian food.

Question 4. Not all delicious foods are necessarily healthy, while not all nutritious foods are always enjoyable. Share your thoughts along with a few examples.

Answer:

I agree with this statement. Many tasty foods such as burgers, pizzas, chips, chocolates and soft drinks contain excess sugar, salt and unhealthy fats, so they should be eaten only occasionally. On the other hand, foods such as green leafy vegetables, sprouts, fruits, millets and salads are rich in nutrients, although some people may not find them very tasty. Therefore, we should choose foods based on their nutritional value rather than taste alone.
