Researchers from Lille University of Science and Technology in France have highlighted that foods high in resistant starch, including bananas, legumes, sweet potatoes, and white rice, may help modulate inflammation and support digestive health. This conclusion appears in research summarized for Frontiers in Nutrition .
The article is a scientific synthesis of existing studies that investigate the properties of resistant starch and its potential impact on human health. Resistant starch, also known as indigestible starch, resists digestion by pancreatic enzymes and behaves similarly to dietary fiber as it moves through the gastrointestinal tract. Upon reaching the large intestine, resistant starch serves as nourishment for beneficial gut bacteria, contributing to a healthier microbial balance .
Across multiple studies, the review suggests that the positive effects of resistant starch on the gut microbiome can enhance digestion and lower the likelihood of constipation and bloating. In addition to the foods already mentioned, other typical sources include corn and cashews, all of which contain notable levels of resistant starch that may be relevant to everyday diets .
Beyond gut health, the research also points to a potential reduction in systemic inflammation linked to the intake of resistant starch. This abdominal and systemic anti-inflammatory effect is thought to arise from the antioxidant properties of these foods, which help neutralize oxidative stress and protect cells from damage caused by free radicals and similar compounds .
Historical discussions about resistant starch have emphasized its accessibility and practical dietary implications. The current synthesis reinforces that common staples can contribute meaningfully to health outcomes without requiring drastic changes in eating patterns. For individuals seeking to balance flavor and wellness, the evidence supports including a variety of resistant starch sources—such as familiar fruits, vegetables, legumes, and grains—in regular meals to support gut function and potentially reduce inflammatory processes .
