Acetate

Short Chain Fatty Acids (SCFA): Acetate, n-Butyrate and Propionate are produced by anaerobic bacterial fermentation of indigestible carbohydrate (fiber).

Acetate is the most abundant SCFA in the colon and makes up more than half of the total SCFA detected in feces.

Possible cause:

Imbalance among anaerobic organisms in the colon. Elevated % recovery of acetate suggests an overgrowth of anaerobic flora, specifically Clostridium.

Possible considerations:

- Assess Bifidobacteria

- Further Testing: Clostridium difficile EIA

Low SCFA may indicate inadequate fiber intake, an unbalanced commensal bacterial population, or impaired bowel health.

Potential Source or Association:

- Decreased carbohydrate or fiber intake

- Low anaerobic or commensal bacteria: dysbiosis

- Altered levels of SCFA have been associated with compromised mucosal health and increased colonic inflammation

Therapeutic Considerations:

- Increase dietary carbohydrate and fiber intake (fruits, vegetables, legumes, and whole grains)

- Evaluate and treat abnormalities of commensal gut bacteria

- Consider prebiotic supplementation

Acetate is the most abundant SCFA in the colon and makes up more than half of the total SCFA detected in feces. These beneficial SCFA have anti-inflammatory properties, provide energy to nourish the colonic epithelial cells and intestinal microbiota, and exert numerous positive effects on gut homeostasis.
