Frequently Asked Questions
Broccoli contains a potent phytochemical that activates enzymes protecting cells, offering defenses against various diseases such as heart disease, neurodegenerative diseases, diabetes, and cancer. This phytochemical also aids in fighting viruses and respiratory illnesses, making it beneficial for immune support against conditions like COVID-19.
The extraordinary broccoli phytochemical, called sulforaphane, is emitted by plants like broccoli to ward off predators. While harmful to insects, sulforaphane stimulates the production of protective enzymes in humans, safeguarding cells from damage caused by free radicals, toxins, and inflammation. Studies have indicated that sulforaphane provides protection against cancer and various chronic diseases.
Research has shown that broccoli sprouts rich in sulforaphane can lower indicators of viral load in the body, boost immune response, and potentially act as an antiviral agent against influenza and hepatitis C. While investigations concerning COVID-19 are ongoing, preliminary studies suggest that sulforaphane may offer defense against respiratory distress.
Sulforaphane has displayed potential in reducing inflammatory damage to the lungs and enhancing survival rates in conditions like acute respiratory distress syndrome (ARDS). Human trials have demonstrated that sulforaphane can diminish virus-induced inflammation in the lungs.
Studies have revealed that sulforaphane enhances lung protection, detoxifies pollutants, and could potentially serve as a therapy for asthma. Additionally, sulforaphane has exhibited protection against Helicobacter pylori infection, which is associated with peptic ulcers and stomach cancer.
High levels of sulforaphane can be found in broccoli sprouts, as well as in Brussels sprouts, cauliflower, kale, cabbage, and bok choy. To maximize sulforaphane content, it is advised to avoid overcooking broccoli and consume it raw or lightly cooked to preserve its enzyme activity. Supplements are also an option for those who prefer an alternative source.
