What foods contain gut irritant?

There are several foods that may act as gut irritants for some individuals. However, it is important to note that not all individuals will have the same response to these foods, and some people may be able to tolerate them without any issues. Some examples of gut irritant foods include:

  1. Gluten-containing grains: Wheat, barley, and rye contain gluten, a protein that can trigger inflammation in the gut and exacerbate symptoms in people with celiac disease or non-celiac gluten sensitivity. (1)
  2. Dairy products: Many people have trouble digesting lactose, a sugar found in milk and dairy products, leading to bloating, gas, and other digestive symptoms. Additionally, some people may be sensitive to the proteins in dairy products, such as casein and whey. (2)
  3. Processed and high-fat foods: Foods that are high in fat or heavily processed can be difficult to digest, leading to bloating and other digestive discomfort. (3)
  4. Spicy foods: Spicy foods, particularly those containing capsaicin, can irritate the lining of the stomach and cause digestive distress. (4)
  5. FODMAPs: Fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAPs) are a group of carbohydrates that are poorly absorbed in the small intestine and can cause bloating, gas, and other digestive symptoms. FODMAPs are found in a variety of foods, including wheat, onions, garlic, beans, and some fruits. (5)
  6. Alcohol: Alcohol can irritate the lining of the stomach and intestines, leading to inflammation and digestive symptoms. (6)
  7. Coffee: Coffee, particularly when consumed in large amounts or on an empty stomach, can stimulate the production of stomach acid and irritate the lining of the digestive tract. (7)
  8. Artificial sweeteners: Some artificial sweeteners, particularly those containing sugar alcohols like sorbitol, can be difficult to digest and cause bloating and other digestive discomfort. (8)
  9. Raw cruciferous vegetables: Raw cruciferous vegetables, such as broccoli, cauliflower, and cabbage, contain compounds that can be difficult to digest and can cause bloating and gas in some people. (9)
  10. Nightshade vegetables: Some people may be sensitive to nightshade vegetables, such as tomatoes, eggplant, and peppers, which can irritate the gut and exacerbate digestive symptoms. (10)

The Human Milk Oligosaccharide - 2'-Fucosyllactose (2'-FL) Prevents Intestinal Inflammation, Study Finds

July 12, 2024 6 min read

Human milk oligosaccharides (HMOs), particularly the glycan known as 2’-Fucosyllactose (2’-FL), have been a cornerstone in neonatal nutrition, offering the first sweet taste and vital energy while establishing a thriving gut microbiome. Recent studies have expanded the understanding of these substances, with research showing 2’-FL's pivotal role in not only fostering beneficial gut bacteria but also in potentially mitigating adult conditions such as colitis. The Schalich et al. (2024) study further explores this by investigating 2’-FL's ability to modulate gut microbial metabolism, suggesting a promising future for HMOs in adult disease prevention and therapy, particularly for inflammatory bowel diseases like colitis.
