Antioxidant and Anti-inflammatory Properties
As an antioxidant, quercetin helps protect your body against damage caused by free radicals, which are unstable molecules that can contribute to oxidative stress and cellular damage. This protection is essential in maintaining good overall health and potentially reducing the risk of developing chronic conditions.
Similar to other well-known antioxidants such as resveratrol and vitamin C, quercetin can help minimize oxidative stress and promote a healthy balance of antioxidants in your body. By doing so, you can experience various health benefits, including improved heart health and protection against certain types of cancer.
In addition to its antioxidant properties, quercetin is also known for its anti-inflammatory effects. Inflammation is a natural response of your immune system to protect your body from harm. However, chronic inflammation can lead to potential health issues. Quercetin works to reduce inflammation by inhibiting the production of inflammatory molecules in your body.
By incorporating foods rich in quercetin into your diet, you can reap the benefits of its antioxidant and anti-inflammatory properties, which can contribute to improved overall health and well-being. It’s important to remember that moderation is key, as excessive consumption of any supplement or nutrient can lead to unintended side effects.
