Peanut skins are often disposed of, but they’re packed with tons of nutrients and bioactive compounds that can significantly benefit our health. From their high antioxidant levels to their rich fiber content, peanut skins offer more than many people realize.
Research continues to reveal the potential health-promoting properties of peanut skins, including their role in supporting heart health, gut health, blood sugar regulation, and even cancer prevention. If you’re curious about what these paper-thin skins can do for your wellness, read on to discover the incredible benefits of incorporating peanut skins into your diet.
How Are Peanut Skins Good For You?
Antioxidants
Peanut skins are packed with antioxidants, especially polyphenols like resveratrol and flavonoids, which play a huge role in fighting oxidative stress in the body. Oxidative stress occurs when there’s an imbalance between free radicals and antioxidants, leading to cell damage, which can contribute to aging and various diseases. The antioxidants in peanut skins help neutralize free radicals, protecting cells and potentially reducing the risk of chronic diseases like heart disease and cancer.
Gut Health & Fiber
Peanut skins are filled with dietary fiber, a key nutrient for maintaining a healthy digestive system. Fiber helps support regular bowel movements and promotes the growth of beneficial gut bacteria, which are important for overall gut health. A fiber-rich diet also helps reduce the risk of digestive disorders, such as constipation and diverticulosis, and can contribute to a lower risk of colon cancer. With their high fiber content, peanut skins can be a valuable addition for those who are looking to improve their gut health naturally.
Anti-Inflammatory Effects
The polyphenols and flavonoids in peanut skins are antioxidants thatalso exhibit strong anti-inflammatory properties. Chronic inflammation in the body has been linked to numerous health issues, including heart disease, arthritis, and certain cancers. By including peanut skins in your diet, you can experience their natural anti-inflammatory effects to help reduce inflammation and support long-term health. These compounds work at a cellular level, where they can suppress the release of inflammatory substances in the body and provide an extra layer of protection against inflammation-related diseases.
Blood Sugar Regulation
Peanut skins may also benefit those looking to manage blood sugar levels, thanks to their fiber and polyphenol content. Fiber slows down digestion, leading to a more gradual release of glucose into the bloodstream, which can help prevent spikes in blood sugar levels after meals. Polyphenols have also shown to improve insulin sensitivity and allow the body to better regulate blood sugar. This makes eating peanuts with skins an excellent choice for those managing diabetes or those wanting to keep their blood sugar levels stable for overall wellness.
Immune Support
Peanut skins contain a range of nutrients that support the immune system, including vitamins, minerals, and antioxidants that are essential for a healthy immune response. Resveratrol in peanut skins protects immune cells from damage and allows them to function effectively. Polyphenols and other bioactives in peanut skins can also support immune health by reducing oxidative stress and inflammation, both of which can weaken immunity. By adding peanut skins to your diet, you build your body’s defenses against bacteria.
Studies: Peanut Skins Contain Health-Promoting Nutrition
Peanut Skin-Fortified Peanut Butters
According to a study published in an issue of Food Chemistry, entitled “Peanut skins-fortified peanut butters: Effect of processing on the phenolics content, fiber content and antioxidant activity,” peanut skins contain high amounts of bioactives and fiber that promote health and prevent disease.
The researchers examined the polyphenol content, antioxidant capacity, and dietary fiber amount in ground peanut skins, before and after they were combined into food, such as peanut butter. They measured the skins’ nutrient content when it was dry-blanched, light-roasted, medium-roasted, and dark-roasted. Regardless of roast type, peanut skins contained high phenolic content, antioxidant capacity, and dietary fiber.
This study shows that peanut skins contain high amounts of bioactives, which are plant substances found to offer health benefits possibly beyond vitamins & minerals. Bioactives such as polyphenols work as antioxidants to protect against heart disease, cancer, and stroke.1 Research shows that antioxidants help prevent oxidative damage in the body that can lead to heart disease and cancer.2 Peanut skins have the highest antioxidant levels compared to other parts of the peanut, and roasted peanut with skins have a higher antioxidant capacity than blueberries. Peanut skins also contain high amounts of fiber, which promotes satiety and weight management, according to research.3
Peanut Skins & Leukemia
A recent study from the University of Wisconsin – Madison, published in Current Developments in Nutrition, has found that polyphenols in peanut skins may inhibit the growth and spread of childhood leukemia cells. Lab tests showed that bioactive compounds in peanut skins reduced cancer cell proliferation in children for up to 72 hours post-application.
This data highlights peanut skins’ potential role in cancer prevention, adding to the growing evidence of their health benefits. The new research highlights the value of including peanuts, especially with their nutrient-packed skins, as part of a healthy diet that may contribute to cancer prevention.
With their nutrients, antioxidants, fiber, and anti-inflammatory properties, peanut skins are a powerful addition to a strong diet. Whether through fortified peanut butter or simply choosing to enjoy peanut skins, adding this into your diet is an easy way to experience their nutrition benefits. Experience the full power of peanuts by including their nutrient-rich skins and enjoy a simple yet impactful boost to your health.
