Vegan Diet And Gas: Tips To Reduce Flatulence

If you've recently gone vegan, you may have noticed an increase in flatulence. This is a common side effect of a vegan diet, and it's usually temporary. The main culprit is fibre, which is found in large quantities in beans, fruits, and veggies. When you switch to a vegan diet, you're getting a lot more fibre than your body is used to processing, so your body needs time to adjust. In the meantime, there are several things you can do to reduce the amount of gas you're experiencing, such as introducing high-fibre foods slowly, drinking more water, and eating more probiotics.

Introduce high-fibre foods slowly

Introducing high-fibre foods slowly is one of the most important steps you can take to reduce flatulence when adopting a vegan diet. Fibre is the main culprit behind vegan farting. When you go vegan, you tend to eat a lot more beans, fruits, and vegetables, and that means your body is getting a lot more fibre, which it isn't used to processing in such large quantities.

The human body cannot digest fibre as a source of calories. Instead, it sweeps through the system and cleans things out, arriving intact in the large intestine, where gas is produced as bacteria feed on it. This gas can cause farting or a feeling of bloating.

The good news is that your body will usually adjust to the increased fibre intake over time, and the gas may decrease naturally. So, if you've recently adopted a vegan diet, be patient and give your body time to adjust. In the meantime, there are several things you can do to help ease the discomfort of excess gas.

Firstly, it's important to introduce high-fibre foods gradually. This gives your body more time to adjust to the increased fibre intake. Start with just a few tablespoons of beans per day and slowly increase the amount over time. You can use an app like Cronometer to monitor your total fibre intake and gradually increase it. In addition to beans, other high-fibre foods to be mindful of include whole grains like whole wheat, as well as lentils, chickpeas, kidney beans, onion, garlic, leek, broccoli, and cauliflower.

It's also a good idea to keep a food journal to identify any problem foods that may be causing excess gas. This can help you steer clear of those foods or introduce them more slowly. You can also try temporarily reducing or eliminating gas-producing vegetables like broccoli, cabbage, and cauliflower.

Another tip is to choose canned legumes over dried legumes, as they are generally better tolerated due to their lower FODMAP content. FODMAPs are fermentable and indigestible carbohydrates that can cause symptoms in people with sensitive guts or IBS. If you do choose dried legumes, try soaking them overnight and discarding the water, as this can help remove some of the gas-producing compounds.

Finally, consider your meal timings and portion sizes. If you typically have infrequent but large meals, try switching to more frequent, smaller meals. This will reduce the amount of gas-producing foods you're consuming in one sitting.

Keep a food journal to identify problem foods

Keeping a food journal can be an effective way to identify problem foods that may be causing excess flatulence on a vegan diet. This is because a vegan diet typically involves a significant increase in fibre-rich foods, especially vegetables and beans, which can lead to an increase in gas production. By keeping a food journal, you can track what you eat and identify any patterns that may be contributing to excess gas.

When keeping a food journal, it is important to be detailed and consistent. Record all the foods you eat, including beans, raw cruciferous vegetables, and whole wheat products, as these are common culprits for causing gas. Additionally, note the portion sizes and any relevant preparation methods, such as whether the beans were canned or soaked, or if the vegetables were raw or cooked. This information will help you identify specific triggers.

You may also want to record how your body feels after consuming different foods. For example, you can note any physical sensations, such as bloating, discomfort, or the urge to pass gas. It may be helpful to rate the intensity of these sensations on a scale to better understand the impact of different foods.

By analysing your food journal, you may start to notice patterns or correlations between certain foods and increased gas or discomfort. For instance, you might discover that beans or cruciferous vegetables, such as broccoli or cauliflower, are more likely to cause gas when consumed in larger portions or when raw. This information can guide you in making adjustments to your diet.

Once you have identified problem foods, you can consider reducing or eliminating them temporarily to see if your symptoms improve. However, it is important to ensure that you still meet your nutritional needs and maintain a balanced diet. You can also try reintroducing the foods gradually at a later stage to see if your body has adjusted and can better tolerate them.

Eat more slowly and chew your food well

Eating slowly and chewing your food well can help to reduce the amount of air you swallow while eating, which can contribute to bloating and flatulence. Taking the time to chew your food thoroughly can also aid digestion by reducing the amount of large food particles that need to be broken down in the gut. This means there is less undigested food for gut bacteria to feed on, thereby reducing gas production.

Chewing your food slowly can also help prevent overeating, which may make it easier for your body to process the food you consume. It is also beneficial to be mindful of the size of your meals, as large meals can lead to increased gas production. Instead, having smaller meals more frequently can help to reduce the amount of gas-producing foods consumed in one sitting.

In addition to eating slowly and chewing your food well, it is important to be mindful of the types of food you are consuming. A vegan diet often includes high amounts of fibre-rich foods, such as beans, legumes, and cruciferous vegetables, which can lead to increased gas production. Introducing these high-fibre foods gradually and keeping a food journal can help identify which foods may be causing excess gas.

It is also beneficial to cook gas-inducing foods, such as broccoli, cauliflower, and cabbage, rather than consuming them raw. Cooking these vegetables can help break them down, making them easier to digest and reducing the amount of gas produced.

Cook your beans thoroughly

One of the main causes of flatulence for vegans is beans, and there are several ways to prepare them to reduce their gas-inducing effects. One way is to cook your beans thoroughly. Cooking your beans until they are soft, or even slightly overcooking them, can make them easier to digest and reduce the amount of gas they produce. Additionally, cooking beans with a small piece of seaweed, such as kombu or wakame, or a bay leaf, can also help to reduce their gas-inducing properties.

Another way to reduce the gas-inducing effects of beans is to soak them overnight and discard the water before cooking. This is because beans contain oligosaccharides, a type of indigestible carbohydrate that can cause gas. Soaking beans and discarding the water can help to remove some of these oligosaccharides, making them easier to digest and less likely to cause gas. This method is especially useful for dried beans, which tend to be less tolerable than canned beans due to their higher FODMAP content.

It is also important to introduce beans and other high-fibre foods slowly when transitioning to a vegan diet. A sudden increase in fibre intake can cause digestive issues, so it is recommended to start with small amounts of beans and gradually increase the amount over time. This allows your body to adjust to the higher fibre content and reduces the likelihood of experiencing excessive gas.

In addition to preparation methods, there are other strategies to reduce flatulence when following a vegan diet. These include increasing water intake, choosing fruits with less sugar, eating smaller meals, and chewing food slowly. It is also important to be mindful of other gas-inducing foods, such as cruciferous vegetables (broccoli, cauliflower, cabbage, etc.), and to consider taking digestive enzymes or probiotics to aid digestion.

Eat probiotics and fermented foods

Probiotics are good bacteria that help your gut transition into a different kind of bacterial environment, which can help with gas. Probiotics, with the help of prebiotics, create short-chain fatty acids like butyrate. These acids create an environment in your gut where sulfide-producing (smelly) bacteria can't thrive, resulting in less smelly farts.

Some vegan-friendly sources of probiotics include:

• Supplements (be sure to check that they are vegan)
• Fermented foods such as sauerkraut, water kefir, kimchi, kombucha, tempeh, and miso

When it comes to supplements, look for a high count of "CFUs" (colony-forming units) and include strains of bacteria such as Lactobacillus acidophilus and Bifidus ("Bifidobacterium").

It's important to be gradual when introducing probiotic foods and supplements. If you add too many at once, you may experience worse gas for the day. Give your gut a chance to transition by easing into it.
