Food is what people and animals eat to survive. Food usually comes from animals or plants. It is eaten by living things to provide energy and nutrition. Food contains the nutrition that people and animals need to be healthy.
The consumption of food is enjoyable to humans. It contains protein, fat, carbohydrates, vitamins, and minerals. Liquids used for energy and nutrition are often called "drinks". If someone cannot afford food they go hungry.
Food for humans is mostly made through farming or gardening. It includes animal and vegetable sources. Some people refuse to eat food from animal origin, like meat, eggs, and products with milk in them. Not eating meat is called vegetarianism. Not eating or using any animal products is called veganism.
Food produced by farmers or gardeners can be changed by industrial processes (the food industry). Processed food usually contains several natural ingredients and food additives (such as preservatives, antioxidants, emulsifiers, flavor enhancers). For example, bread is processed food. At home, food is prepared in the kitchen, by the cook. The cook sometimes uses a cookbook. Examples of cooking utensils are pressure cookers, pots, and frying pans.
