  1. it works for anti aging .im 56 years old,i drank a 55 gallon drum of it last night,when i woke up today i was about 6 months bald,i have no teeth and i have been drooling on myself all day.but im so happy,no worries and no taxes and no wife.

  2. What do you do if you have IBS and any cruciferous vegetable causes extreme gastrointestinal discomfort and makes you shit yourself, causing a Pavlovian response of discomfort even if you don't eat it?

  3. Rhonda, I'm here a little late from one of your recent videos. I know you always recommend getting nutrients through natural sources but I get a little overwhelmed with all the volume of cruciferous vegetables. I'm already doing your first version Kale smoothie every day, would you suggest supplementing with super sprout broccoli sprout powder? How much per day?

  4. Cruciferous vegetable intake is just a leading indicator of an overall healthier lifestyle, or someone who attempts to eat healthy.

    I highly doubt its any particular compound in the vegetables that cause the lower lung cancer rate. We already know that Americans had much higher rates of lung cancer with a lower population of smokers compared to the Japanese.

    I'd bet eating a highly inflammatory and insulinogenic diet is what increases cancer risk, and anything that replaces glucose/fructose and omega 6 fatty acids will reduce the risk.

  5. Questions. . . For the cruciferous family (brassica) in p53 precursors. Does it matter to feminize them fully using banana and the predominant stage in enigma? They are bisexual, does it cause any hermafridation if an indoor of 1,ooo Watt bulb @ 42" is displaced? What are the certainties of no hermi'ing the bulb(s). Does it even matter? Just curious. . . Can present a 453,000 square foot indoor grow using LED for Bloom and vegetative states, with sources of either hydroponics or regular, but thinking of cruciferous seedlings as the business model. Any advice?

  6. Dosage of 40 to 60mg? When I look for Sulforaphane capsules, they typically contain about 400mcg. Where are people finding supplements that contain 40mg+ of sulforaphane?

  7. Without stating the study and or studies it just sounds like many "other" experts, but not credible information, specific studies or reports are needed for all the of the
    time spent at this video.

  8. Ok I am done for this week from this much information! Basically (daily take 50g of Brussels Sprouts extract, Omega-3s from krill oil, drink green tea and watch your videos) and live 110 years

  9. Great Video Rhonda! We truly appreciate the work your doing, and more importantly making the information available for free! You are amazing. I have been using Spout Living's FD Sprout Mix- Broccoli & Kale product from my store in Canada.
    This product is a freeze dried Broccoli and Kale Sprouts ground into a powder for easy use. I use them in shakes and smoothies.
    Check out the link if you interested!

  10. when i drink two cups a day of broccoli soup with tumeric and black pepper my PSA (I have prostate malignancy, very small, so we watch it) goes down 20% in 5 months. When I go off of it, it goes back up. I've tested this 3 times and it is always the same. Broccoli with tumeric and black pepper (read The Anti-Cancer Diet book and decide for yourselves!!) lowers PSA which, if you already have prostate cancer DOES indicate cancer increase or decrease, (from all that I've read.) So, that's it. judge for yourself. the worst that can happen is you eat broccoli. beats nourishing cancer.
