The first requirement for good health is often cited as adequate and balanced nutrition.

Here's why:

• Foundation for Body Functions: Nutrients from food provide the building blocks and energy needed for all bodily functions, including growth, repair, and maintenance.
• Immune System Support: Proper nutrition is essential for a strong immune system, helping the body fight off infections and diseases.
• Disease Prevention: A balanced diet can reduce the risk of chronic diseases such as heart disease, diabetes, and certain types of cancer.

While other factors like exercise, sleep, and mental well-being are also crucial, nutrition forms the fundamental basis for overall health.
