Raw Red Kidney beans (Phaseolus vulgaris) at a level as low as 1% of diet have been shown to cause death in rats in two weeks. Beans cooked at 100 degrees for 30 mins, and incorporated at a level as high as 20% of diet do not retard growth when tested against casein. However, when beans which have cooked at 70 degrees for 30 mins are incorporated growth retardation is almost as great as that which occurs when raw beans are fed. The small amount of lectin present in beans cooked at 70 degrees might be responsible for this effect.
未加工的红芸豆（菜豆）在饮食中所占比例低至1%时，已被证明会在两周内导致大鼠死亡。与酪蛋白相比，在100摄氏度下煮30分钟并在饮食中所占比例高达20%的豆子，不会阻碍生长。然而，当加入在70摄氏度下煮30分钟的豆子时，生长迟缓几乎与喂食生豆时一样严重。在70摄氏度下煮的豆子中存在的少量凝集素可能是造成这种影响的原因。
