In recent years, there has been a growing interest in the potential health benefits of sulforaphane (SFN), a naturally occurring compound found in certain vegetables. Studies have revealed its remarkable properties, ranging from antioxidant and anti-inflammatory effects to liver detoxification support and potential cancer-fighting abilities. Let's explore the benefits of sulforaphane and discover how you can incorporate it into your diet.
Sulforaphane is a powerful phytochemical that belongs to the group of isothiocyanates. It is most abundantly found in cruciferous vegetables such as broccoli, cauliflower, kale, Brussels sprouts, and cabbage. Young broccoli sprouts and raw crucifers are especially potent sources. This sulfur-rich compound is easily digestible, and your body does an excellent job putting it to use:
Antioxidant Benefits: SFN works indirectly as an antioxidant to reduce the risk for Type II Diabetes (DMII). Oxidative stress is an important contributor to DMII and its complications, such as peripheral neuropathy. In studies, taking supplemental sulforaphane from broccoli sprout extract has been shown to lower blood glucose and A1c levels. The antioxidant effects of SFN also are thought to support heart health and improve cholesterol levels.
Anti-inflammatory Benefits: SFN has been shown to suppress inflammatory processes in the body by down-regulating, or helping to turn off, proinflammatory enzymes. It’s also known to enhance the activity of natural killer cells - white blood cells that attack and destroy diseased and infected cells - preventing and treating both acute and chronic inflammation.
Cancer Treatment: In test tube and animal studies, concentrated SFN has exhibited powerful anticancer properties. It’s been shown to kill early stage cancer cells and slow tumor growth. It’s also known to inhibit metastasis (spread of cancer to other organs) and the growth of blood vessels that feed tumors, but more human studies are needed to inform its clinical use. Nevertheless, it’s exciting to see evidence that it can slow so many of the processes that make cancers so deadly.
Detoxification Support: Perhaps the best-known benefit of sulforaphane is its ability to activate the liver’s phase 2 detoxification enzymes, rendering toxins less harmful as the liver works to excrete them. This both helps to improve liver function and protect the liver from damage. It also supports the synthesis of glutathione, an antioxidant produced by the liver that is essential for tissue building and immune function. SFN is the most potent of all known phase 2 activating substances, and it provides significant protection against food-borne and environmental toxins.
Additionally, sulforaphane is being actively researched for its ability to protect against brain damage, particularly neurodegenerative conditions such as Alzheimer’s and Parkinson’s disease.
Thanks to the nutritional content and year-round availability of cruciferous vegetables, it’s easy to incorporate more sulforaphane into your diet. While young broccoli sprouts are the most potent, raw or lightly steamed vegetables such as broccoli, kale, cauliflower, Brussels sprouts, and bok choy also contain significant amounts of SFN and are wonderful to include in your diet for a multitude of reasons. SFN is extremely safe, but it does interact with some medications, so it’s a good idea to consult your physician before increasing your consumption if you’re taking any medications regularly.
