Which two specific flavonoids are noted for being present in significantly higher amounts in kale compared to many other common vegetables?
Answer
Quercetin and Kaempferol
Kale's high antioxidant profile is supported by the abundance of specific flavonoid compounds that offer protective benefits within the body. Among these, quercetin and kaempferol stand out due to their high concentration relative to other common vegetable sources. Research suggests that kale contains markedly elevated levels of these two specific compounds. The presence of these flavonoids is linked to various systemic advantages, including potential anti-inflammatory effects, which contribute to the overall resilience kale builds against internal oxidative stress when consumed regularly.
