Digestion

Section reviewed by gastroenterologist Arpi Gasparyan

Both beans are a rich source of fiber; however, since they are richer in fiber, lima beans are ideal legumes to add to our diets. A high-fiber diet decreases the risks of colorectal cancer and diverticular disease and improves gut microbiome and bowel movements. (1)(2)(3)

Unlike lima beans, fava beans are high in FODMAPs, poorly digested carbs that may cause bloating, gases, and abdominal pain.  People with IBS or on a low FODMAP diet should avoid fava beans. 

G6P deficiency patients 

Individuals with G6P deficiency should not consume fava beans since they induce a hemolytic attack. Foods that are often cooked with fava beans should be restricted, falafel is more often done with fava beans, and this should be restricted. (5)

Cyanogenic glycosides

It is important to cook and properly prepare lima beans because they contain toxic cyanogenic glycosides in humans. By thoroughly cooking lima beans, this toxin is eliminated. (6)
Fava beans can be eaten raw; they do not contain cyanogenic glycosides.
