Overview
A clear starting point
Nutrition is a critical part of health and development, playing a vital role in preventing malnutrition and diet-related noncommunicable diseases. A healthy diet involves consuming a balanced mix of carbohydrates, proteins, healthy fats, vitamins, and minerals. Public health organizations like the WHO and CDC emphasize the importance of eating a variety of whole foods, including fruits, vegetables, legumes, and whole grains, while limiting the intake of added sugars, sodium, and unhealthy fats. The ICMR-NIN Dietary Guidelines for Indians also highlight the need for varied, wholesome foods and moderation in processed food consumption to support lifelong wellness.
