Beans are one of the most nutritious and affordable foods you can add to your diet. They’re packed with plant-based protein, fiber, vitamins, and minerals, making them a staple in many traditional cuisines around the world.
However, many people avoid eating beans regularly because they can sometimes cause gas, bloating, or digestive discomfort. The good news is that a simple kitchen technique—used for generations—may help make beans much easier to digest.
Let’s take a closer look at why beans sometimes cause digestive issues and how a small preparation trick can make a big difference.
Why Beans Sometimes Cause Gas
Beans naturally contain carbohydrates called oligosaccharides. These sugars are healthy plant compounds, but the human digestive system has difficulty fully breaking them down.
When oligosaccharides reach the large intestine, gut bacteria begin to ferment them. While this process is a normal part of digestion, it can produce gases such as hydrogen and methane.
This fermentation is what often leads to:
Bloating
Gas
Abdominal discomfort
For people who are not used to eating beans regularly, these effects can be even more noticeable.
The Baking Soda Soaking Trick
One traditional kitchen trick that may help reduce these digestive issues is adding a small pinch of baking soda to the water when soaking beans.
Baking soda is slightly alkaline, which can help break down some of the complex sugars in beans before they are cooked.
How it works
The alkaline environment created by baking soda may help soften the bean skins and begin breaking down certain carbohydrates, including some of the oligosaccharides responsible for gas production.
