Have you ever wondered how much quercetin in broccoli you’re actually getting? This cruciferous powerhouse is beloved for its versatility, flavor, and nutritional benefits. But beyond vitamins and minerals, broccoli boasts a potent antioxidant called quercetin, known for its potential health-promoting properties.
Deciphering the Quercetin Content
Quercetin is a flavonoid, a plant pigment found in various fruits, vegetables, and grains. It’s often referred to as a “super-antioxidant,” capable of fighting free radicals, those unstable molecules that can damage cells and contribute to chronic diseases.
So, how much quercetin can you expect from a serving of broccoli? The answer depends on factors like the variety, growing conditions, and preparation methods. Generally, a single cup of cooked broccoli provides approximately 28 milligrams of quercetin. This amount might seem small, but it contributes to your daily intake of this valuable nutrient.
