Mechanisms Underlying the Effects of Sweet Potato Skin on Gut Health
Polyphenols present in sweet potato skin, such as anthocyanins and carotenoids, are thought to be responsible for its beneficial effects on gut health. These polyphenols may exert their effects through multiple mechanisms:
1. Modulation of the gut microbiota
Sweet potato skin polyphenols can influence the composition and activity of the gut microbiota, leading to an increased abundance of beneficial bacteria and reduced growth of pathogenic bacteria.
2. Enhancement of gut barrier function
Sweet potato skin polyphenols may improve gut barrier function by increasing the production of mucus and tight junction proteins, reducing inflammation and permeability in the gut.
3. Antioxidant activity
Sweet potato skin polyphenols, particularly anthocyanins and carotenoids, have potent antioxidant activity, which can help reduce oxidative stress and inflammation in the gut.
4. Modulation of immune responses
Sweet potato skin polyphenols may influence immune responses in the gut, reducing inflammation and promoting a healthy immune environment.
Antioxidant Activity of Sweet Potato Skin Extract: A Comparative Analysis
Sweet potato skin extract has been shown to possess high antioxidant activity compared to other edible plant sources. The ORAC (Oxygen Radical Absorbance Capacity) value of sweet potato skin extract is approximately 7,000 μmol TE/100g, which is significantly higher than that of other plant sources, such as carrots (3,200 μmol TE/100g), beets (5,600 μmol TE/100g), and spinach (4,600 μmol TE/100g).
This suggests that sweet potato skin extract may be a rich source of antioxidants, which can help mitigate oxidative stress and inflammation in the body.In conclusion, sweet potato skin consumption may exert a positive influence on gut health, improving gut microbiota diversity and reducing inflammation and oxidative stress in the gut. The polyphenols present in sweet potato skin are thought to be responsible for these effects, and further research is needed to fully understand their mechanisms of action.
With its high antioxidant activity, sweet potato skin extract may be a valuable addition to the diet for promoting overall health and well-being.
The Potential Role of Sweet Potato Skin in Chronic Disease Prevention: Is Sweet Potato Skin Good For You

Sweet potato skin, once discarded, has been identified as a treasure trove of nutrients and bioactive compounds. The skin’s nutrient profile is similar to that of the flesh, with a rich blend of vitamins, minerals, and antioxidants. Researchers have begun to investigate its potential role in preventing chronic diseases, such as cardiovascular disease, and the evidence suggests a promising relationship.Consuming sweet potato skin may reduce the risk of cardiovascular disease by lowering blood pressure, improving lipid profiles, and reducing inflammation.
The polyphenolic compounds present in sweet potato skin, such as anthocyanins and carotenoids, have been shown to exert antioxidant and anti-inflammatory effects, which may contribute to a reduced risk of cardiovascular disease.
Antioxidant-Mediated Anti-Inflammatory Effects
The antioxidant-mediated anti-inflammatory effects of sweet potato skin compounds can be attributed to their ability to scavenge free radicals and modulate pro-inflammatory signaling pathways. The polyphenolic compounds present in sweet potato skin have been shown to inhibit the activation of pro-inflammatory enzymes and cytokines, which are involved in the inflammatory response. This anti-inflammatory effect may contribute to the potential health benefits of sweet potato skin, including a reduced risk of chronic diseases.
