This mineral can have a positive effect on diabetic people or at risk of suffering from this disease.

By incorporating red onions into your diet, you can take advantage of the various vitamins and minerals they offer. From vitamin C and quercetin to chromium, these nutrients can contribute to their general wel l-being and promote a healthier lifestyle.

Red Onion as a Source of Antioxidants

One of the main antioxidants in red onions is quercetin. Quercetin is a flavonoid that has been shown to have powerful antioxidant and anti-inflammatory properties. This compound helps neutralize free radicals, reducing the risk of chronic diseases such as heart disease, diabetes and certain types of cancer. Additionally, quercetin has been associated with a lower risk of allergies, as it can inhibit the release of histamines in the body.

Did you know?

Red onions contain higher levels of quercetin compared to other onion varieties, making them a great choice for increasing your antioxidant intake.

Additionally, red onions are a good source of another antioxidant called anthocyanin. Anthocyanins are pigments that give red onions their vibrant color. These compounds not only act as antioxidants, but also have anti-inflammatory, anti-cancer and cardiovascular protective properties. Research suggests that anthocyanins may help reduce the risk of chronic diseases, including cardiovascular diseases and certain types of cancer.

The Role of Red Onions in Heart Health

Red onions are not only known for adding a burst of flavor to various dishes, but also for their potential to promote heart health. A key compound in red onions is quercetin. Quercetin belongs to a class of plant pigments called flavonoids, which have been widely studied for their potential health benefits. Flavonoids are known for their antioxidant and anti-inflammatory properties, which may help improve cardiovascular function.
