Which of the following is an example of a plant-based protein?

Refried beans are an excellent example of a plant-based protein because they are made from pinto beans or black beans, which are legumes. These beans are rich in protein and provide essential amino acids that contribute to a balanced diet, particularly for those who may follow vegetarian or vegan lifestyles. Plant-based proteins, like the ones found in beans, are also typically lower in saturated fat compared to animal proteins, making them a healthier option for many individuals.

Chicken, fish, and eggs are all animal products, which means they are categorized as animal-based proteins. While they are also sources of high-quality proteins, they do not fall under the plant-based category. The inclusion of refried beans as a plant-based protein highlights the importance of plant sources in providing nutritional value within a diverse diet.
