Good sources of protein include:

Protein is an essential macronutrient that plays a vital role in the body, including building and repairing tissues, making enzymes and hormones, and supporting immune function. Good sources of protein are those that contain higher amounts of amino acids, the building blocks of proteins.

Beans, peanut butter, and eggs are excellent choices because they provide a substantial amount of protein. Beans are a plant-based protein source rich in fiber and essential nutrients, peanut butter offers protein along with healthy fats, and eggs are considered one of the most complete protein sources, containing a perfect balance of essential amino acids.

In contrast, rice and bread primarily consist of carbohydrates rather than protein. Fruits and vegetables generally contain very low protein levels and are more valued for their vitamins, minerals, and fiber. Butter and cream are high in fats and do not provide any significant protein content. Therefore, the combination of beans, peanut butter, and eggs stands out as the best source of protein among the given options.
