Butyrate fermentation is a process that produces butyric acid via anaerobic bacteria. This process occurs commonly in clostridia which can be isolated from many anaerobic environments such as mud, fermented foods, and intestinal tracts or feces. [1]
β-Hydroxy β-methylbutyric acid [note 1] (HMB), otherwise known as its conjugate base, β-hydroxy β-methylbutyrate, is a naturally produced substance in humans that is used as a dietary supplement and as an ingredient in certain medical foods that are intended to promote wound healing and provide nutritional support for people with muscle wasting due to cancer or HIV/AIDS.
No single food can protect against cancer, but eating more foods that fight it will help reduce the risk of developing the disease, the American Institute for Cancer Research notes.
Apart from butyrate, F. prausnitzii produce formate and D-lactate as byproducts of fermentation of glucose and acetate. [21] [7] Lower than usual levels of F. prausnitzii in the intestines have been associated with Crohn's disease, obesity, asthma and major depressive disorder.
The American Cancer Society have stated that "there is some evidence from human and lab studies that consuming traditional soy foods such as tofu may lower the risk of breast and prostate cancer, but overall the evidence is too limited to draw firm conclusions".
Acetate, propionate and butyrate are the three most common SCFAs. [3] Butyrate is particularly important for colon health because it is the primary energy source for colonocytes (the epithelial cells of the colon). [1] [2] The liver can use acetate for energy. [5]
One review estimated that the acceptable daily intake of resistant starch may be as high as 45 grams in adults, [18] an amount exceeding the total recommended intake for dietary fiber of 25–38 grams per day. [19] When isolated resistant starch is used to substitute for flour in foods, the glycemic response of that food is reduced. [20] [21]
Because of its involvement with these functions, it is hypothesized that butyrate can act as a protective agent against colon cancer and various inflammatory bowel diseases. [7] [9] [10] [12] Butyrate plays a key role in colon cancer by switching its role concerning cellular proliferation and apoptosis depending on the state and conditions of ...
