Which of these would not lead to a meal with complete proteins?

A meal that contains complete proteins includes all nine essential amino acids that the body cannot synthesize on its own. Meat and eggs, dairy and grains, and fish and legumes all provide multiple sources of complete protein, as they include animal products or complementary plant proteins.

On the other hand, vegetables and beans often do not provide a complete protein source on their own. While beans are good sources of protein, they lack certain essential amino acids such as methionine, which is primarily found in grains and animal products. Most vegetables are low in protein and do not usually contain adequate amounts of the essential amino acids on their own, making it necessary to combine them with other protein sources to create a meal that provides the full range of amino acids.

Thus, the combination of vegetables and beans typically does not result in a meal containing complete proteins unless paired with additional protein sources that fulfill the missing amino acids.
