Beans are an excellent source of plant-based protein and fiber. However, their high fiber content can cause digestive issues like bloating and gas for some people. Many wonder if soaking beans before cooking can help reduce these unwanted side effects.
How Beans Cause Gas
Beans contain complex sugars called oligosaccharides that our bodies cannot fully digest. When these oligosaccharides reach the large intestines gut bacteria ferment them producing gas as a byproduct. Some of the oligosaccharides found in beans include
- Raffinose
- Stachyose
- Verbascose
These indigestible sugars are the main reason behind gas and bloating after consuming beans. Beans also contain proteins called lectins that can irritate the digestive tract and cause gas and bloating.
Benefits of Soaking Beans Before Cooking
Soaking beans before cooking provides several benefits:
-
Reduces oligosaccharides Soaking beans can help reduce oligosaccharides by about 20-25%. Soaked beans ferment less in the intestines, resulting in less gas production.
-
Deactivates lectins: Soaking beans deactivates lectins, making beans easier to digest and less likely to cause gas.
-
Shortens cooking time Soaked beans cook faster as they absorb water during soaking This makes them softer and less likely to cause gas,
-
Improves texture: Soaked beans have a softer, creamier texture that’s easier to digest.
-
Enhances flavor: Soaked beans absorb flavors better during cooking.
-
Increases nutrient absorption: Soaking may increase absorption of nutrients like iron, zinc and calcium by reducing phytic acid.
How Long to Soak Beans to Reduce Gas
To effectively reduce oligosaccharides and lectins, beans need to be soaked for at least 12 hours. Some recommendations for soaking times include:
-
12-24 hours for optimal gas reduction
-
8 hours minimum
-
Overnight soak for 12-18 hours
Soaking for less than 8 hours may not provide significant benefits for reducing gas and improving digestibility.
Tips for Soaking Beans
Follow these tips for soaking beans properly to reduce gas:
-
Rinse beans before soaking to remove debris. Pick out any damaged beans.
-
Use a large container and add 10 cups of water for every 1 cup of dried beans. They will expand during soaking.
-
For every 1 pound of beans, use 6-8 cups of water.
-
Change the soaking water 2-3 times to further remove oligosaccharides.
-
Soak at room temperature or in the refrigerator. Avoid soaking beans at temperatures above 75°F to prevent fermentation.
-
Add a tablespoon of baking soda or acidic ingredients like vinegar, lemon juice or whey to the soaking water. This can help neutralize lectins and oligosaccharides.
-
Discard soaking water after beans have soaked sufficiently. Rinse the beans well before cooking.
Cooking Tips to Further Reduce Gas
After soaking, cook beans using these tips to further minimize gas:
-
Rinse soaked beans well before cooking.
-
Cook beans thoroughly until very soft. Undercooked beans cause more gas.
-
Change the cooking water 2-3 times. Pour out water used for boiling and add fresh water before simmering.
-
Add herbs, spices and acidic ingredients to the cooking water.Try bay leaves, onions, garlic, vinegar, lemon juice, tomatoes.
-
puree or mash some of the cooked beans and mix back in before serving. Pureed beans cause less gas.
Summary
Soaking beans for at least 12 hours before cooking can significantly reduce the oligosaccharides and lectins that cause gas and bloating. Be sure to rinse and change the soaking and cooking water several times. Combining proper soaking with thorough cooking and flavorful seasonings can help minimize digestive discomfort from bean dishes. With these simple preparation tips, you can enjoy all the nutritional benefits of beans without the unwanted side effects.
Beans, Beans, the Magical “Fruit”: The More You Eat the Less You Toot!
You can’t go wrong with beans as a food. They are full of protein, fiber, and vitamins and minerals that are good for your body. Unfortunately, some people choose to avoid this healthful food because they fear intestinal gas or flatulence. However with all their benefits, it’s important to regularly enjoy this simply delicious, naturally nutritious food.
Why Do Beans Produce Gas?
Beans contain fibers called oligosaccharides (all-uh-go-SACK-are-rides), which are non-digestible, fermentable fibers that cause gas. While this might sound like a bad thing, it’s actually a very good thing. These fibers survive the acidic stomach and don’t get digested in the upper part of the gut. They make their way intact to the colon where they are fermented by beneficial bacteria. Gas is created during this fermentation process. This is a good sign because it means that these good bacteria are being fed, kept alive, and improved by the right foods. This may help keep the gut and other body parts from getting sick. “Prebiotics” are fibers from foods like beans that can get into the gut without getting broken down and help the good bacteria grow and do their job. ”.
We know that the health of our gut affects our physical and mental health as a whole [1]. Consuming plant-based foods that contain these non-digestible fibers may keep our bodies regular and our gut healthy.

Does soaking beans help with gas?
Soaking can help remove some of the oligosaccharides and make it easier for your body to break down the beans, making it less likely for you to have gas after eating them. Overnight soaking can help you dissolve 75% to 90% of the oligosaccharides into the soaking water, which you can throw away after the soaking’s done.
Does increasing bean consumption help with indigestion?
When talking about consuming beans and digestion, what we think of is the way that beans are prepared and the undesirable effects it can cause, such as flatulence. To avoid problems like this, it is necessary to soak the beans in water overnight and change the water two to three times. Without a doubt, beans are not the most recommended food to aid digestion, but they play a very important role in our diet.
Should you soak beans before cooking?
Simmer the beans gently until tender. The purpose of soaking beans depends on who you ask. Many people prefer soaking beans, especially with the hot soak method, because it makes the beans more tender after they are cooked. Others soak their beans to make the beans easier to digest and to prevent gas.
How do you get gas out of dried beans?
This is by far the easiest method and the one the USDA stands behind. Simply place dried beans in a container, cover them with water and let them soak. They’ll need to soak eight to 12 hours, but the key to eliminating the gas is draining and rinsing every three hours. Yup, you read that right.
