How can I counteract the effect of beans? I get some kind of Gastro Intestinal disorder each time eat boiled beans.
Please how can I stop this nagging health problem.

Its also an issue for me but it is said that when you change the water after boiling it for some time, it removes the chemical causing constipation from the beans. But i haven't really tried it.

I think most people get the opposite effect from beans. Most people have runny stomach after eating beans instead of constipation. Other effects are flatulence and general stomach upset. To stop that, soak your beans for at least 3 hours, rinse and put it in pot and add water, let it boil for about 5 minutes, discard the water and continue cooking till done. All the above will reduce oligosaccharides elements which cause flatulence, bloating and general discomfort you get after eating beans. Try this cooking method and see how it goes.

^^^ Men, that's some work to eat beans that isn't that great a thing to eat anyway! Just kidding.

For flatulence or constipation
* You can change the type of beans - if you are in Nigeria, the white bean is less guilty than the red types common in the SW.
* Boil your beans well - there should be no "seeds" when you are eating them.
* If you are fund of eating large amounts, reduce it - it may be okay to gorge yourself on rice, but not beans. Eat a little quantity of it with a little quantity of garri or bread or something else you feel comfortable with.

For runny stomach or "gassing", there is only one solution that works 100%
* Eat your beans hot. You don't like hot food, okay, here's what you do: When you set down the pot from the fire, dish out the stuff and wait for it to cool a few minutes and eat IMMEDIATELY. Once you keep it waiting it's already infected and you will get what is coming to you.
