Sources of food can be broadly classified into two groups: plants and animals. Plants provide us with fruits, vegetables, rice, wheat, maize, pulses, and other food crops that are rich in proteins, fibers, carbohydrates, minerals, vitamins, and fats. Vegetables, roots, leaves, and stems of some plants are edible and provide essential nutrients for the bodys health and upkeep. On the other hand, animal products such as milk, eggs, and meat are important examples of food from animals. Animal products are also a rich source of nutrients, including protein, iron, and minerals. Seafood is another dietary source that provides a rich source of nutrients, including protein, fat, and minerals. Meat, poultry, fish, and beans are some of the most common types of foods from animals. Cereals are by far the most important source of total food consumption as measured in calories. In addition to these, there are also other sources of food such as nuts, seeds, and legumes that are rich in nutrients. A balanced diet that includes a variety of these food sources is essential for maintaining good health.
