Which combination provides a good plant-based protein source for vegetarians and vegans?

• A. Beef and Pork
• B. Soybean and Quinoa
• C. Eggs and Cheese
• D. Milk and Butter

Answer: (B)

Understanding how to get protein from plant-based foods is key here. Soybeans and quinoa are both plant-based protein sources that provide essential amino acids, making them suitable for vegetarians and vegans who avoid animal products. Soybeans supply all the essential amino acids and are a staple in vegan diets, while quinoa is one of the rare plant foods that is a complete protein on its own, offering all nine essential amino acids along with fiber and minerals. The other options include animal-derived foods or dairy, which aren’t plant-based or vegan. So the combination of soybeans and quinoa best fits a plant-based protein source for vegetarians and vegans.
