Difference between nutrition and food in Korean
영양·음식

영양nutrition
Nutrition (영양) is the healthy energy and goodness your body gets from food. We use this word when talking about food that helps you grow, stay strong, and feel well. You can say a food has a lot of nutrition or that someone needs good nutrition.

음식food
Food means things that people eat. In Korean, 음식 means meals, dishes, or food in general. You can use this word when talking about cooking, restaurants, shopping, or what you like to eat.
The difference
음식 means the food itself, like rice, soup, or fruit. 영양 is the good things in food that help your body.
