5. Brussels Sprouts
Like broccoli, Brussels sprouts are a member of the cruciferous family of vegetables and contain the same health-promoting plant compounds.
Brussels sprouts also contain kaempferol, an antioxidant that may be particularly effective in preventing damage to cells (17).
One animal study found that kaempferol protected against free radicals, which cause oxidative damage to cells and can contribute to chronic disease (18).
Brussels sprout consumption can help enhance detoxification as well.
One study showed that eating Brussels sprouts led to a 15–30% increase in some of the specific enzymes that control detoxification, which could decrease the risk of colorectal cancer (19).
Additionally, Brussels sprouts are very nutrient-dense. Each serving provides a good amount of many vitamins and minerals, including vitamin K, vitamin A, vitamin C, folate, manganese and potassium (20).
Summary
Brussels sprouts contain an antioxidant called kaempferol, which may protect against oxidative damage to cells and prevent chronic disease. They may also help enhance detoxification in the body.
