Resistant starch consumption linked to reduced liver fat

Research published in the journal Cell Metabolism indicates that daily consumption of resistant starch may help reduce liver fat in adults with fatty liver disease. A study led by researchers from Shanghai Jiao Tong University and Shanghai Sixth People’s Hospital involved participants consuming 40 grams of maize-based resistant starch daily for four months.

The findings showed that approximately 75% of participants experienced a significant response, with some seeing an average reduction in liver fat of nearly 40% to 57% compared to control groups. Researchers suggest that the mechanism involves resistant starch bypassing digestion in the small intestine to reach the large intestine, where it is fermented by gut bacteria. This process appears to influence liver health through changes in the gut microbiota.

While the results are promising, experts note that individual effectiveness varies based on personal gut bacteria composition. Dietary sources of resistant starch include oats, barley, brown rice, chickpeas, red beans, green beans, potatoes, and green bananas. Additionally, cooling cooked rice or potatoes can increase resistant starch content. However, medical professionals emphasize that resistant starch should be part of a balanced diet and not a replacement for formal medical treatment, weight control, or regular exercise.
