Diet and nutrition play a major role in preserving health and preventing disease. A daily dietary nutrient intake level that is sufficient to meet the nutrient requirements of 97-98% of healthy individuals in a particular life stage and gender group is known as the recommended dietary allowance (RDA), according to ICMR-NIN (2020). Micronutrients are the essential vitamins and minerals that are required for all normal cellular and molecular functions and are obtained through diet. The World Health Organization (WHO) defines "micronutrients" as substances that are required by the body in minuscule amounts for the regulation of vital functions. This study has been employed a quantitative approach, to observe the knowledge of nutrition, food hygiene practices and how these impact on health among young adults ranging from 18 to 45 years of age from Delhi. Participants completed a questionnaire assessing Nutritional Knowledge, dietary practices and food hygiene practices in order to obtain their role in overall health. It was clear from the population inputs, which were collected as a pie chart, that most people have a reasonable understanding of what constitutes a healthy diet. A whopping 79.4% of people do not skip breakfast in the morning, which is crucial to reviving the body's metabolism following a lengthy night of fasting. According to the survey's results, half of the population knew a fair amount about nutrition. It was clear that 50% of people were aware of the proper daily intake of fats, proteins, and carbohydrates; nearly 93% of them were aware that adding fiber to the diet is beneficial; approximately 78% of people were aware that protein is necessary for muscle growth; and approximately 70% of people were aware that packaged foods should not be consumed. By the end of the study, it was concluded that there is a direct link between food habits, nutritional awareness, food safety precautions, and health. This research emphasized on studying the dietary pattern, nutritional knowledge and food hygiene practices among individuals for good health. Further research and interventions are warranted to enhance nutritional knowledge, dietary practices and ultimately promote healthier lifestyles among the target population.
