What happens if we eat food from a single group of foods everyday?
If we eat food from a single food group every day, our body will not get all the necessary nutrients required for proper growth and health. For example, eating only energy-giving foods like rice and wheat will lead to deficiency of body-building nutrients (proteins) and protective nutrients (vitamins and minerals). This can cause weakness, poor immunity, and various deficiency diseases. A balanced diet requires foods from all three groups - energy-giving, body-building, and protective foods.
Explanation
The chapter explains that food serves three main purposes: providing energy (from foods like rice, potato, wheat, maize, banana, honey, millets, butter, ghee, oil), helping in body building (from pulses, legumes, soybeans, chickpeas, peanuts, tofu, milk, cheese, eggs, meat, fish), and protecting from diseases (from fruits and vegetables like carrot, orange, lemon, papaya, spinach, cabbage, guava, amla, tomato). Eating from only one group leads to nutritional deficiencies.
