Side Effects

Though loaded with nutrients, consuming edamame and green beans may cause undesirable effects on some people.


Edamame may trigger breast and bladder cancers. Isoflavone mimics estrogen, a hormone that, if produced in excess, triggers the growth of breast and bladder cells. 

It is therefore advisable to consume edamame moderately if one has other predisposing factors. It could also lead to an underactive thyroid. 

Phytoestrogen found in edamame is a risk for people with kidney disorders. It could trigger kidney failure.

Edamame contains high amounts of oxalate, a component of kidney stones, which may increase the risk of their formation.

Green beans

Green beans contain high levels of Vitamin k, which might interfere with blood thinners. You may consider minimizing your consumption of green beans if you are on blood thinning medication.

Phytic acid in green beans may bind certain minerals and make it hard for the body to absorb them.

They contain lectins that cause gas and abdominal discomforts.
