Are Beans a Complete Protein?

Some vegans and vegetarians may find it difficult to complete their protein nutritional requirement if they rely solely on plant based food items such as beans.

Protein is important for building and developing muscle and tissue and most people get their recommended daily requirement of protein through the food they consume such as meat products. According to the Center for Disease Control and Prevention, a healthy individual should consume around fifty (50) to one hundred seventy five (175) grams of protein per day to meet the recommended daily dose of protein which should ideally be around ten (10%) to thirty-five (35%) percent of total calories consumed per day. The question then is- are beans a complete protein?

While beans have one of the highest protein contents within plant based food items, beans do not have all the essential amino acids needed in an individual’s diet.

Beans though, obviously have an advantage over their meat based counterparts as they can provide a significant amount of the protein required by the body without all the harmful saturated, trans fat and cholesterol normally associated with red meat and other meat based food items.

How much protein do beans have exactly? Evidence suggests that soybeans, one of the richest sources of protein for plant-based food items, have around 28.5 grams worth of protein per cup.
