Cruciferous vegetables have a compound called sulforaphane and it is in very high levels in broccoli sprouts. There are so many health benefits to broccoli sprouts, as you will see below, but the reason it is in JNC is for helping with Osteoarthritis OA. One of the ways it helps is by reducing an enzyme called MMP, which is an enzyme that destroys cartilage and becomes overactive in OA. In one mouse study it was shown to decrease activation of this enzyme by 80% [1]
In a clinical trial in Britain people with OA ate broccoli soup 4 times a week for 12 weeks (which contained one cup serving of broccoli), had a 9 point drop in their WOMAC score which is about a 30% improvement. [2]
It also decreases inflammation in joints and throughout the body by activation of the NRF2 Pathway which activates 500 genes that: control inflammation, increase anti-oxidants, elimination of toxins such as benzene, and increase cytoprotective enzymes. [3,4]
It increases Chondrocyte production of chondrocytes (up to 30% in the lab), and decreases chondrocyte cell death. [5,6]
Many other health benefits such reducing cancer rates, helping with cardiovascular disease, controlling diabetes and increasing antioxidant protection by increasing glutathione levels. 5+ servings/week of broccoli (about ½ cup of broccoli) (or other cruciferous vegetables) had decrease cancer rates by 40 to 60% depending on the type of cancer. One serving is about ½ cup of broccoli. Broccoli sprouts have 100x more of the active component called sulforaphane. The amount of broccoli sprouts in JNC is about equivalent to 1 serving for Formula 2 and 2 servings for Formula 1. [7,8]
