What is the major food source?

The major food source for humans is typically plant-based foods, with staples like grains (such as rice, wheat, and corn), fruits, and vegetables forming the foundation of diets worldwide. In many cultures, animal products like meat, dairy, and eggs also play a significant role in nutrition. These food sources provide essential nutrients, energy, and variety to diets across different regions. Additionally, legumes and nuts contribute valuable proteins and healthy fats.
