So I have recently been trying out some, no-background, no nonsense science posts about current topics in the literature. This series has been well received, so today I have returned to follow this protocol yet again and hopefully produce for you something that is both interesting and not a big time investment!
For this post let us turn to a topic that I file under the category of pleasantly surprising. The article we will briefly discuss was published in the journal Nature: Scientific Reports and is titled "Isothiocyanates are detected in human synovial fluid following broccoli consumption and can affect the tissues of the knee joint."
Broccoli Is A Super Food
We all know that broccoli is a SUPER FOOD right? It's quite healthy for us, high in nutrients, high in fiber, low in calories. Tastes great (especially with cheese!!!), what's not to love?
The internet (and science too) is full of wild claims about the wondrous health properties of broccoli. It Fights Cancer due to the compound sulforaphane. Interestingly this particular compound is also thought to help prevent arthritis [3] due to its protective properties of cartilage (in our joints!)
What Were The Authors Studying?
They were continuing to study broccoli in relation to arthritis, specifically this compound solforaphane. Solforaphane (or 1-isothiocyanato-4-methylsulfinylbutane) is a compound that is produced in our bodies through processing of another compound called glucoraphanin, which is made by broccoli. Now as I mentioned there have been a variety of previous studies on solforaphane where people have identified quite a bit about how it accumulates in the body after eating broccoli (including in people on a high broccoli diet). [4], [5]. What researchers have also found is that despite the fact that this compound accumulates in the body, there is no known toxicity issue from consuming normal amounts of broccoli in the diet, even indefinitely.
In this study the authors wanted to see if the arthritis and joint protection from this compound were derived from it actually accumulating in those locations, or if the effect was due to it's work elsewhere in some other biochemical pathway.
Briefly What Did They Find?
- People who ate more broccoli (which was high in the glucoraphanin) compound has higher levels of isothyocyanate compounds in their blood (this is the class that solforaphane belongs to), with an increase in solforaphane specifically noted.
- In this study people who were eating a high glucoraphanin broccoli diet did not show a reduction in cartilage damage
- However the people eating the high broccoli diet did have itothyocyanates found in the fluid between their joints (synovial fluid), while the control group did not.
- They also saw a change in the protein composition in these synovial joint fluids, for only those on the high broccoli diet.
Conclusions
The authors illustrated in this article for the first time that broccoli consumption results in an accumulation of Solforaphane and other isothyocyanate compounds in joint fluid (these are the protective compounds), and noted a change in the protein composition of these fluids. These findings support prior research indicating that solforaphane has a direct joint protective activity. A number of these protein composition changes were reductions in ones which have been previously identified to associate with conditions like rhumatoid arthritis such as Calreticulin, which is found in higher levels in the joints of those suffering from arthritis [6]. The authors findings here illustrate potential mechanisms by which the protective properties of solforaphane might come.
I Have Arthritis... Should I Eat More Broccoli?
Well according to this article the answer isn't just broccoli as the control group here was also eating it. Rather the key was the group eating broccoli that was high in glucoraphanin. Beyond this, there are no guarantees of miracle cures, or that if you are eating broccoli that is high in glucoraphanin you won't develop arthritis. Nevertheless, considering all of the other health benefits associated with eating this nutrient dense veggie, it doesn't seem like the worst plan to try to incorporate it into your diet if you don't already eat it, or to try to eat it regularly if you already do ( I know I eat broccoli all the time! Yay me! )
Additional Interesting Research Edit 6-15-2017
A recent article published in the journal Science: Translational Medicine titled "Sulforaphane reduces hepatic glucose production and improves glucose control in patients with type 2 diabetes". Studying the very same compound Sulforaphane, which we discussed in this post originally, has found that high concentrations (administered in a pill) had a beneficial effect on blood glucose levels in diabetics. As far as the effect from consumption of broccoli is concerned, you would have to eat 5 kilograms of it daily, to get a comparable amount of the compound in your system (and I don't think anyone is going to start eating that much broccoli... sooo much fiber). So this is not something to think too much about (from a nutrition standpoint) nevertheless it is just another positive aspect of broccoli and these isothyocyanate compounds that it produces.

Very good post backed up with scientific evidences in those published articles. I started eating broccoli like crazy about 3 years ago when it was clear to me that I would need to go for a major gynecological surgery (myomectomy including cystectomy). The issues I had were as a result of estrogen dominance. Brocolli helped me a lot to reduce bloating in my stomach, so much so that a girlfriend of mine noticed it and asked me what I was eating. I told her that every evening, for dinner, I was eating steamed broccoli with fish drizzled with a teaspoon of cold pressed hemp seed/olive oil. The indole-3-carbinol in broccoli is responsible for assisting the liver to clear excess estrogen. It's quite interesting to know from your post that broccoli also helps relieve arthritis. Well done, @justtryme90!!! Thank you for sharing.

The amount of glucorphanin is not consistent across all cruciferous veggies, so while that may be somewhat true, it is not entirely consistently true. This article seems to indicate that as far as the protective activities reported here are concerned that high glucorphanin is necessary. Broccoli happens to be particularly high in this particular compound, when compared to other similar vegetables. I linked a source to this info in a different comment.

Very thorough.. esp. sighting all your sources.. I wonder how many other Cruciferous vegetables contain glucoraphanin ? I'm pretty sure broccoli, cabbage, brussel sprouts, cauliflower, and a few others are all hybridizations of the Sea Cabbage plant..

Brassica oleracea is a plant species that includes many common foods as cultivars, including cabbage, broccoli, cauliflower, kale, Brussels sprouts, collard greens, savoy, kohlrabi, and gai lan.
In its uncultivated form, it is called wild cabbage, and is native to coastal southern and western Europe.

Broccoli is delicious but if you have a thyroid condition,you should be aware of how long you cook your broccoli. Broccoli(and other cruciferous vegetables)contains goitrogens which can potentially have an impact on thyroid function, so make sure you cook your broccoli for a good 30 minutes.
https://en.wikipedia.org/wiki/Cruciferous_vegetables
Also, why would you put cheese on broccoli? You're ruining it! ;-)

The jury is still out on thyocyanates (goitrogens just refers to any compound that can damage the thyroid, lets be more specific) and thyroid function.
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4135245/
The cited article here is a review, in which they discuss the findings of a variety of articles. Some of the articles published on the subject found a positive correlation between thyroid cancer and consumption of cruciferious vegetables (like broccoli), others saw no correlation, some saw a correlation, but only if the person had an iodine deficiency in their diet. At this point I don't think there is a very clear link between broccoli consumption and thyroid troubles.
well if you want to break down the thyocyanates then yes longer cook times will degrade the compounds, however these very same compounds are the ones discussed in this article with arthritic protective activities (Solforaphane is one of these compounds, and is the subject of this entire post!)
I like to do lots of things with it. Sometimes I like to add cheese with broccoli, its tasty. Roasting broccoli with some fresh garlic is also tasty. I mean there are a lot of things you can do with it other than just plain old steamed (which is also fine). I it raw too. :)

This is the case with so many aspects of life. Everything has benefits and drawbacks. If the benefits far outweigh the drawbacks then one should still go for it. Broccoli has just way too much good going for it. Heck yeah, bring on the broccoli!

(Edited: Oop, I see some people already posted this fact!) Good stuff! I was just reading about how broccoli was developed from the same original species as so many other vegetables we eat today. It turns our broccoli, broccolini, cauliflower (ok no surprises yet right?), kale, cabbage, brussel sprouts, collard greens, and more are just cultivars/varieties of the same species. https://en.wikipedia.org/wiki/Brassica_oleracea

If prevention is found more often then causation then it prevents. If causation is found more often the prevention then it's a causative agent. Experiments are complicated, methods aren't always good. That figure is a bit disingenuous don't you think? ;)

Actually, it very much is. It's polemic and exaggerates a lot.
On a more serious note however I would like to emphasize that this study was performed on 40 patients only. It might contain some valuable insights but IMO it also has to be treated with caution as 40 is a pretty small sample size.
P.S: I'm not trying to mess with you here. Your article is very well written and the study seems to have been performed with great care. However, it's just too early to draw any conclusions from it without further investigations.

I will say 1 thing related to arthritis, and 1 thing related to broccoli.
Arthritis: I've heard CBD (Cannabidiol) is great for arthritis and similar painful medical conditions.
Broccoli: I'm not sure about helping with arthritis, although your conclusions would suggest it does help. But what I have to say is this: I'm not sure if Broccoli makes arthritis better, but it makes my flatulence worse LOL great post by the way!

Fun Science-y fact : The main reason Broccoli helps arthritis is because arthritis is worsened by inflammation and broccoli has way more Omega-3 than Omega-6 and generally reduces Omega-6 consumption in the diet
This isn't to say fish is good for this however due to contaminates in it, as well as most high Omega-3 fish has tons of Omega-6 too.
The best solution is vegetables, fruits are good too, and some Chia/Hemp/Flax seeds regularly :)
