Why does garlic give me gas?

In this guide, we will address and answer the query, “why does garlic give me gas?” and answer other similar related questions like “what happens when you eat too much garlic?” and “how much garlic should you eat?”

Why does garlic give me gas?

Garlic is a high FODMAP food, meaning it contains a lot of carbohydrates that can be difficult for the digestive system to break down. Carbohydrates in garlic make digestion difficult because they ferment in the intestines and produce gas.

The fermentation of carbohydrates in garlic can cause bloating for a few reasons. First, garlic is a high-fiber food, and when fiber ferments in the gut, it can produce gas. 

Additionally, garlic contains fructans, a type of carbohydrate that is particularly prone to fermentation. Lastly, alliums like garlic are known to promote the growth of gut bacteria, which can also contribute to bloating.

Garlic can also stimulate the release of stomach acid, which can contribute to heartburn and indigestion. 

 Finally, some people may have an intolerance or allergy to garlic, which can also cause digestive distress.

How can you relieve gas caused by garlic?

It is recommended to drink warm water with lemon and honey, or chamomile tea. Others suggest taking a warm bath or placing a heating pad on the stomach.

Chamomile tea is thought to relieve bloating by acting as a carminative. This means that it helps to expel gas from the intestines. One study showed that chamomile tea was effective in relieving bloating and gas in people with IBS.

 You can also have probiotic supplements or activated charcoal. Activated charcoal can help relieve bloating by binding to gas-forming compounds in the digestive tract and preventing them from being absorbed. This can help to expel gas and reduce bloating.

What are the side effects of eating too much garlic?

Bad breath

The sulfur compounds found in garlic are responsible for bad breath when you eat too much garlic. When garlic is digested, sulfur is released into the bloodstream and eventually makes its way to the lungs. The sulfur is exhaled, and this is what causes bad breath.

There are a few ways to prevent garlic breath. One is to chew on a sprig of parsley after eating garlic. This will help to neutralize the garlic odor. Another is to drink a glass of milk after eating garlic.

 The milk will help to coat the sulfur molecules and prevent them from being exhaled. Finally, brushing your teeth and tongue after eating garlic will help to remove the odor-causing molecules from your mouth.

Stomach problems

Garlic can cause stomach upset when it is consumed in large amounts or when it is consumed raw. When garlic is cooked, it is broken down into smaller molecules that are less likely to cause stomach upset. 

Raw garlic is more likely to cause stomach upset because it has not been broken down and is thus more likely to irritate the stomach lining. Garlic can also cause gas and bloating.

If you eat too much garlic, you may experience heartburn, diarrhea, or flatulence.

It is speculated that the high acidity level of garlic may contribute to heartburn by irritating the esophagus. Additionally, garlic is a known trigger for gastroesophageal reflux disease (GERD).

How much garlic should you eat?

There is no recommended amount of garlic to eat, as it can vary depending on personal preferences. Some people may enjoy eating a clove or two of raw garlic, while others may find this to be too strong. It is generally recommended to start with a small amount and gradually increase it as desired.

In terms of cooked garlic, the National Institutes of Health (NIH) recommends that adults consume no more than 4 cloves per day.

If you are looking for specific health benefits from garlic, it is important to consult with a healthcare professional to ensure you are taking the appropriate amount. Garlic supplements can also be taken in capsule form, and the recommended dosage will be included on the product label.

Is it better to have garlic raw or cooked?

Raw garlic is far superior in terms of nutrition and health benefits. Cooked garlic may have some health benefits, but it doesn’t compare to the nutritional powerhouse that is raw garlic.
