Nutritious food contains water, protein, fat, carbohydrates, as well as vitamins and minerals that are often affordable.

The aim is to understand how the level of nutritional knowledge, eating habits, and physical activity of students at SMA N 04 Kotabumi are interconnected. The research design uses a cross-sectional approach and is quantitative in nature. In this study, a Simple Random Sampling technique was used, and the sample consisted of 75 respondents from SMA N 04 Kotabumi.
