Introduction
Nutrition plays a major role in maintaining good health and supporting overall well-being. The human body requires proper nutrients to function correctly, grow, repair tissues, and produce energy for daily activities. Healthy eating habits help people stay active, maintain a healthy weight, and reduce the risk of many diseases. Without proper nutrition, the body may become weak, tired, and more vulnerable to health problems.
In modern society, many people consume processed foods, sugary drinks, and unhealthy snacks because of busy lifestyles and convenience. Poor eating habits can negatively affect both physical and mental health over time. Understanding the importance of nutrition helps individuals make better food choices and develop healthier lifestyles that support long-term wellness.
