Plant-Based Diets: The Gas-Producing Truth

A plant-based diet can cause gas, and it's completely normal. When transitioning to a plant-based diet, people often consume more fibre than they did previously. Fibre passes through the small intestine to the large intestine, where bacteria break it down, producing gas in the process. This can cause bloating and discomfort. However, the body will adjust to the new diet over time, and the amount of gas produced will decrease. In the meantime, there are some tricks to reduce flatulence, such as drinking more water, eating smaller meals, and avoiding gassy carbonated beverages.

High-fibre foods can cause gas

When switching to a plant-based diet, it is common to experience an increase in gas and bloating. This is because plant-based diets are typically high in dietary fibre, which can be hard for the body to digest. The average American consumes about 15-20 grams of fibre a day, whereas a plant-based diet can contain more than 70 grams of fibre. This sudden increase in fibre can be a shock to the body and lead to increased gas production.

Dietary fibre is a type of carbohydrate that is not digested by the small intestine. Instead, it passes through to the large intestine, where it is broken down by bacteria. This process of fermentation produces gas. Soluble fibre is more likely to produce gas than insoluble fibre, as it is more easily fermented by bacteria. Foods high in soluble fibre include lentils, beans, oats, peas, and most fruits.

While high-fibre foods can cause gas, they also have many health benefits. Dietary fibre can help with constipation, reduce cholesterol, remove toxins, and reduce the risk of type 2 diabetes. It is also essential for a healthy digestive system, as it provides roughage for food waste to pass through easily and prevents constipation.

To minimise gas and bloating when consuming high-fibre foods, it is recommended to increase water intake, eat smaller meals, and spread fibre consumption throughout the day. Cooking vegetables can also make them easier to digest, and it is advisable to introduce high-fibre foods slowly to give the body time to adjust.

The body needs time to adjust to a plant-based diet

Transitioning to a plant-based diet is a great way to improve your health and vitality. However, it can take some time for your body to adjust to the increased intake of dietary fibre. Dietary fibre is a type of plant-based carbohydrate that is not easily digested by the small intestine, so it passes through to the large intestine, where it is broken down by bacteria. This process can produce more gas than usual, leading to flatulence and bloating.

When you switch to a plant-based diet, you are likely to be consuming more fibre and carbohydrates than before. This extra fibre reaches the large intestine and is broken down by bacteria, producing gas. Additionally, the bacteria in your gut may not be adapted to your new diet, leading to increased gas production.

The time it takes to adjust to a plant-based diet can vary from person to person. It can take anywhere from a few days to several weeks for your body to adjust to the increased fibre intake. During this time, you may experience digestive issues such as gas and bloating. However, these issues should subside as your body adjusts to the new diet.

Tips for reducing gas and bloating

• Increase fibre intake gradually: Start by adding high-fibre foods to 1-2 meals per day and slowly increase the amount until you are getting 30-35g of fibre per day.
• Drink plenty of water: Water is essential for fibre to work effectively. Without enough water, fibre can have the opposite effect and cause constipation.
• Chew thoroughly: Chewing thoroughly helps break down plant cell walls and increases the surface area for acids and enzymes to attach, optimising the digestion process.
• Eat cooked vegetables: Cooked vegetables are easier to digest than raw vegetables, especially for those with a sensitive digestive tract.
• Spread fibre consumption throughout the day: Instead of adding a lot of high-fibre foods to a single meal, try to eat smaller amounts of fibre at each meal.
• Soak and cook beans properly: Beans can be gassy, but you can reduce the gas production by soaking them overnight, cooking them thoroughly, and draining and rinsing canned beans before use.
• Avoid gas-producing foods: Limit your intake of carbonated beverages, sugar-free gum and candy, and raw cruciferous vegetables like broccoli, cabbage, and cauliflower.
• Try natural remedies: Ginger, fennel, and peppermint can help soothe an angry, bloated gut. You can chew on fresh ginger, sip ginger tea, or try a strong peppermint tea.
• Consider probiotics and digestive enzymes: Probiotics can help your gut bacteria bounce back, while digestive enzymes can provide short-term relief. However, it's best to consult a healthcare professional before taking any supplements.

Soaking and cooking beans can reduce gas

Soaking and cooking beans can significantly reduce their gas-inducing effects. Beans contain fibres called oligosaccharides, which are non-digestible and fermentable, leading to gas production during the fermentation process by gut bacteria. Soaking beans in water for an extended period helps release these gas-producing fibres into the water, and discarding and replenishing the water multiple times during the soaking process can effectively reduce their presence.

There are various methods for soaking beans to reduce their gas-inducing properties. One simple method is to place dried beans in a container, cover them with water, and let them soak for 8 to 12 hours. It is important to drain, rinse, and replenish the water every three hours during this process to eliminate excess sugar starch. For a quicker option, you can add a teaspoon of baking soda to the water and soak the beans for four to eight hours before draining, rinsing, and cooking them. This helps break down the beans' natural gas-making sugars.

Another effective method is pressure cooking. After soaking the beans for four to eight hours, drain and rinse them, then place them in a pressure cooker with water. Set the pressure to high or 15 pounds and cook for 10 to 12 minutes, followed by a natural pressure release.

Cooking beans thoroughly until they are soft is also essential in reducing their gas-inducing effects. Additionally, certain herbs and spices like epazote, ajwain (carom seed), kombu or wakame (seaweed), bay leaf, and asafetida can aid in breaking down the gas-producing fibres.

While soaking and cooking methods can help minimise the gas-inducing properties of beans, it is also worth noting that regularly consuming beans can increase your body's tolerance over time, leading to reduced intestinal gas.

Drinking water helps with digestion

A plant-based diet often includes more fibre than people are used to, and this can lead to increased gas and bloating. This is because fibre passes through the small intestine to the large intestine, where it is broken down by bacteria, producing gas in the process. However, this issue usually resolves itself as the body adjusts to the new diet.

Water acts as a lubricant, facilitating the movement of food through the digestive tract. It softens stools, preventing constipation and promoting regular bowel movements. Dehydration can cause hard stools and constipation, as water is reabsorbed from the colon if the body does not have enough.

Drinking water is also critical for optimal nutrient absorption. Water is the medium through which nutrients are transported from the digestive tract into the bloodstream. Proper hydration ensures the body can efficiently absorb vitamins, minerals, and other essential nutrients.

Additionally, adequate hydration helps maintain the correct balance of electrolytes in the body. Electrolytes are vital for muscle function, nerve signalling, and maintaining fluid balance. Electrolyte imbalances can affect the ability of the muscles in the digestive tract to contract and move food through the system efficiently, potentially leading to bloating, discomfort, and slowed digestion.

To ensure good digestive health, it is recommended that men drink about 3.7 litres of fluids per day, and women about 2.7 litres. It is important to adjust this amount depending on your activity level, climate, and overall health.

Probiotics can help with digestion

A plant-based diet can cause gas, especially when you're transitioning to it from a non-plant-based diet. This is because plant-based diets are typically high in fibre, which can take some time for your body to adjust to. However, there are ways to mitigate this, and one of them is by taking probiotics.

Probiotics are live bacteria and yeasts that have beneficial effects on your body. They help fight off unfriendly microbes and boost your immunity against infections. They can be consumed through natural foods or supplements.

Improving digestion and reducing gas

Fermented foods that contain probiotics can improve your digestion and may reduce gas. Tempeh, for example, is a fermented soy product that is more easily digested than tofu. Fermented drinks like kombucha and kefir are also good sources of probiotics.

Aiding the transition to a high-fibre diet

Probiotics can help your body adjust to the increased fibre intake associated with a plant-based diet. By aiding digestion and promoting a healthy balance of bacteria in your gut, probiotics can make the transition smoother and reduce digestive issues.

Reducing intolerance to certain plant foods

Some people may have ongoing intolerance to certain plant foods, such as beans and raw vegetables, which can cause bloating and gas. Probiotics can help your body adjust to these foods by promoting a healthier gut environment.

Easing digestive issues

Probiotics can help ease digestive issues such as lactose intolerance, diarrhoea, and constipation. They can also help break down and absorb nutrients and medications, as well as produce important nutrients as by-products.

Promoting a healthy gut microbiome

A healthy gut microbiome is crucial for overall health, and probiotics can help maintain this. They can control potentially harmful microbes, reduce inflammation, and keep your bowels regular.

It is important to note that not all probiotics are alike, and different types of microbes function differently in the body. It is recommended to consult a healthcare professional to determine which probiotics may work best for your specific needs. Additionally, while probiotics are generally safe, those with weakened immune systems should exercise caution.
