What is a common source of protein in the diet?

Meat is widely recognized as a common source of protein in the diet due to its high protein content and the range of essential amino acids it provides. Protein is crucial for numerous bodily functions, including building and repairing tissues, making enzymes and hormones, and supporting overall growth and development. Meat, along with other animal products such as fish and poultry, contains complete proteins, which means they offer all the essential amino acids that the body cannot produce on its own.

While fruits, vegetables, and sugars can play a role in a healthy diet, they are not considered significant sources of protein. Fruits and vegetables contain small amounts of protein but are primarily sources of vitamins, minerals, and fiber. Sugars provide energy in the form of carbohydrates, but they do not offer protein content. Therefore, meat stands out as a major protein source within a balanced dietary framework.
