Organic Broccoli Calabrese

£5.50£68.00

Broccoli Calabrese seed is an excellent quality seed and produces a wonderfully large, juicy and peppery tasting sprout, with a good yield. Broccoli Calabrese has been shown to contain high levels of glucoraphanin, the precursor to sulforaphane. If you are looking to increase your sulforaphane consumption, this is the seed to buy.

Broccoli sprouts contain a host of beneficial nutrients and antioxidants. One cup of sprouts contains double the amount of fibre as regular broccoli and 60% of your daily intake of immune-boosting Vitamin C. Broccoli sprouts contain approximately 50 times the amount of nutrients as the vegetable. 

Most importantly, they provide you with sulforaphane. In fact, broccoli sprouts are the richest source of naturally-occurring sulforaphane currently known to science. 

What is sulforaphane and why do we need it?

Plant compounds, or phytochemicals, have been shown to have numerous beneficial effects. Sulforaphane is one of a group of very special plant compounds called isothiocyanates. It has been shown to help the body to heal from a vast amount of serious diseases, including various cancers, autism, inflammation and more. It has also been shown to help prevent healthy people from developing chronic diseases and improve our health. 

How does it work? 

Sulforaphane is not actually present in the intact plants, instead there is a compound called glucoraphanin, which is the precursor to sulforaphane. When the sprouts are chewed, the glucoraphanin gets broken down and reacts with an enzyme contained in the plant tissue called myrosinase, and sulforaphane is produced. Broccoli sprouts have been shown to contain 100 times as much glucoraphanin, which is then converted to sulforaphane, than the vegetable broccoli. 

Sulforaphane is so impressive because of the cytoprotective (cell-protecting) effect it produces. When we consume broccoli sprouts, sulforaphane kick-starts a process in our cells that essentially up-regulates our cells’ protective response. The result is that our cell defenses are ramped up and our immune system is boosted.

For those looking to increase sulforaphane consumption, this is the seed to grow.

10g of seed will produce approximately 100g of sprouts in 4 – 5 days. For maximum sulforaphane harvest sprouts at 3 days old.

Hi, have you had your broccoli calabrese seeds tested for their glucoraphanin content (e.g. the precursor to sulforaphane) to establish if they are a high glucoraphanin variety?

Thanks for getting in touch, and great question.

We haven’t had our Calabrese seed tested for glucoraphanin levels. With all the great research being done lately which has highlighted the tremendous benefits of sulforaphane, interest in this particular aspect of broccoli sprouts has soared. Prior to this, people generally wanted broccoli seed for the numerous health benefits, rather than specifically for sulforaphane. So this is something we have just begun to consider as something our customers may be interested in.

We are currently exploring options with a laboratory to test for glucoraphanin in our freeze-dried sprouts. If we manage to do this, we could extend this to our seed as well. It isn’t a standard test that they offer, as it is a very specialised area, so we are currently trying to figure out if they can do it for us. We are also in talks with our seed supplier to see if they can do this testing on the seed. We will make sure to update you when we have made some progress on this.

Thank you for your helpful response. I work in the field of nutritional medicine and I prefer to embrace a ‘food first’ philosophy rather than supplements whenever possible and practical. I am aware that glucoraphanin (and thus sulforphane levels) can vary considerably across different cultivars of broccoli seeds hence it would be great to know that I was recommending a bona fide high glucoraphanin broccoli seed.
PS – I have recommended your broccoli seeds to a lot of my clients and use them myself!
