Garlic, while beneficial in many ways, can cause stomach pain for some individuals. This is primarily due to its high fructan content. Fructans are a type of carbohydrate that some people have difficulty digesting. This difficulty can manifest as various symptoms, depending on the individual's sensitivity.
The Role of Fructans
-
Fructan Intolerance: Many sources cite fructan intolerance as a major reason for garlic-related stomach upset. Fructans, found in garlic, onions, and other similar vegetables, are poorly absorbed in the intestines of those with this intolerance. This leads to fermentation by gut bacteria, resulting in gas, bloating, and abdominal pain. [Source: livestrong.com, telegraph.co.uk, mindbodygreen.com]

High Fructan Levels: Even for those without a diagnosed intolerance, consuming excessive amounts of garlic can overwhelm the digestive system. The high concentration of fructans can trigger similar symptoms of discomfort. [Source: healthline.com, vinmec.com]

Direct Stimulation: Beyond fructans, garlic's potent compounds can directly irritate the stomach lining, particularly when consumed raw or in large quantities. This irritation can lead to heartburn, a burning sensation in the chest, and other digestive issues. [Source: vinmec.com]

Allicin Sensitivity: In some cases, a sensitivity to allicin, a compound responsible for garlic's pungent smell and taste, might contribute to stomach upset. This is less common but can cause symptoms such as abdominal pain and mouth sores. [Source: quora.com]
Managing Garlic-Related Stomach Pain
-
Reduce Consumption: The simplest approach is to limit your garlic intake. Start with smaller amounts and observe your body's reaction.
-
Cook Garlic: Cooking garlic reduces its fructan content, making it easier to digest for those sensitive to raw garlic.
-
Choose Garlic Supplements: Garlic supplements may be a better option than consuming large amounts of raw or cooked garlic. It allows the potential benefits to be obtained without as much risk.
-
Consider a Low-FODMAP Diet: Individuals with chronic digestive issues might benefit from consulting a doctor or registered dietitian about a low-FODMAP diet, which limits the intake of high-FODMAP foods, including garlic and onions. [Source: mindbodygreen.com]

Consult a Doctor: Persistent or severe stomach pain after eating garlic warrants a visit to a healthcare professional to rule out any underlying conditions or allergies. [Source: quora.com]
