Why do different people need different amounts of nutrients?

Different people need different amounts of nutrients because nutritional requirements depend on factors such as age, growth, physical activity, health condition, and lifestyle. Every person's body has different energy and nutrient needs.

Growing children and teenagers require more nutrients, especially proteins, vitamins, and minerals, because their bodies are developing rapidly. People who perform heavy physical work or exercise regularly need more energy-giving nutrients like carbohydrates and fats to support their activities.

Nutrient requirements may also change according to a person's health. For example, someone recovering from illness or injury may need more proteins and other nutrients to help repair body tissues.

A balanced diet should match the needs of an individual by providing the right amount of carbohydrates, proteins, fats, vitamins, minerals, dietary fibre, and water. Eating according to the body's requirements helps maintain proper growth, strength, energy levels, and overall health.

Therefore, the same diet may not be suitable for everyone because each person's body needs nutrients in different quantities.
