Can You Put Broccoli Seeds in a Smoothie?

After watching Dr. Rhonda Patrick’s podcast interview with Dr. Jed Fahey (Johns Hopkins University), I was compelled to begin growing my own broccoli sprouts.

Broccoli sprouts yield an incredible chemical called sulforaphane, which is associated with anti-aging, reducing fat, and cancer prevention. (For a more detailed overview of sulforaphane, and how it’s produced with the help of glucoraphanin and myrosinase, check out this article).

With much enthusiasm, I went straight to Amazon to piece together the equipment needed to grow these tasty strands of nuclear nutrition at home.

That’s when I realized what a colossal pain in the arse it is… (haha, sorry Rhonda).

It involves buying six glass sprouting jars and routinely filling/replacing the water inside every 4-6 hours. This is necessary to prevent the growth of bacteria. Cycling the planting process (Jar-1 on Sunday, Jar-2 on Monday, Jar-3  on Tuesday, etc) helps if you plan on having fresh sprouts ready each day — although you can freeze them.

That’s when my interest in sprouts got dwarfed by my disinterest in setting timers day and night. Plus I wasn’t thrilled about leaving sprouting jars all over the kitchen.

So I thought, hey, I’ll just buy organic sprouts from the grocery store!

Not so fast… Guess how easy it is for E. coli to contaminate sprouts when they sit stagnant on improperly sanitized shelves… Super easy. Since I’m the type of guy who still hasn’t gone back to Chipotle even though their diarrhea debacle ended in 2015, I decided to pass on those store-bought sprouts.

Then I recalled something Dr. Fahey said in the interview: Broccoli seeds contain more sulforaphane than broccoli sprouts (which already have at least 20x the sulforaphane as actual broccoli).

I make smoothies every day, so why not add broccoli seeds to the mix and get my daily dose of sulforaphane that way?

Looking around online, I couldn’t really find anything about whether or not this would work. So I made myself the guinea pig and did some experimenting.

screen-shot-2017-01-20-at-4-30-54-pmI bought these broccoli seeds. Upon arrival, they reminded me of whole peppercorn kernels. So they needed to be crushed. Since I don’t own a coffee grinder, I used my VitaMix.

A teaspoon of broccoli seeds doesn’t reach the blades, so I added about six ounces of water. That certainly did the trick.

After pulverizing the seeds, you’re left with a frothy cream-colored liquid with a slight green tinge. It smells pleasantly nutty. Not at all pungent, which I was expecting.

Dr. Patrick is careful to remind listeners that the existing research on sulforaphane has only involved broccoli sprouts — not seeds. So she’s openly unsure whether the broccoli seeds would yield the same benefits as organic broccoli sprouts. I suspect she’ll conduct a few experiments with broccoli seeds in the future, and share her results. I’ll update this article if/when that happens.

Until then, I can report no unwanted side effects from personally consuming the crushed seeds. I’ve even had them plain, in just an 8-ounce glass of water. They taste slightly nutty, but otherwise it’s surprisingly easy to drink.

If you want to take a deep dive into the importance of sulforaphane and the Nrf2 pathway as it relates to anti-aging and cancer prevention, here’s the full interview I mentioned:

  1. Great article, I have been looking for more information on broccoli seeds. Do you know how much of sulforaphane in 1 teaspoon of broccoli seeds? How much do we need per day?
    Thank you.

  2. Thanks for experimenting with this and sharing! I too have been making sprout smoothies inspired by Rhonda for a few months now. I don’t mind the sprouting but if seeds work even better, that would definitely be preferable to use. I hope Rhonda does a podcast on this soon! I am also concerned that making my smoothies at night and consuming them the next day might mean less sulforophane is still present.

  3. I too would like to start including broccoli sprouts into my diet but growing them sounds like a hassle. The grinding of the seeds in my coffee grinder would be much easier. How much should I consume daily and weekly? Any help would be great! Thanks for all the helpful info.

    • Sean, I haven’t found any specific recommendations for an exact amount. I personally use 1/2 tsp daily, but have used as much as a full teaspoon in the past.
