Bianca had a great question about heating tea and if it destroys the enzymes or not…

In this episode, I cover this question as well as HIIT training and how much raw food should you eat.

We also have 4 RV names that we’d love for you to vote on…

Kevin Gianni is a health author, activist and blogger. He started seriously researching personal and preventative natural health therapies in 2002 when he was struck with the reality that cancer ran deep in his family and if he didn’t change the way he was living — he might go down that same path. Since then, he’s written and edited 6 books on the subject of natural health, diet and fitness. During this time, he’s constantly been humbled by what experts claim they know and what actually is true. This has led him to experiment with many diets and protocols — including vegan, raw food, fasting, medical treatments and more — to find out what is myth and what really works in the real world.

Kevin has also traveled around the world searching for the best protocols, foods, medicines and clinics around and bringing them to the readers of his blog — which is one of the most widely read natural health blogs in the world with hundreds of thousands of visitors a month from over 150 countries around the world.

  1. the health benefits of the tea far outweigh the minute benefits of any enzymes that might be present.

    there is a lot more to health, healing, and nutrition than just enzymes.

    you do yourself a massive dis-service if you avoid tea because you are afraid to heat it.

    penny wise & pound foolish. not mention dogmatic and ignoring the reality in front of you.

    however, to each their own.

  2. Zak Martin-Kilgour says:

    As far as I know from my studies in herbalism (Planetary herb course), the amount of heat you use on herbal teas is graduated. For any light flowery herbal teas you can extract the medicinal properties very easily with very warm water verging on hot. You can use use very hot water but it’s not necessary.

    Then plant leaves are a little tougher and need slightly hotter water but like you mentioned if you use preboil water you’ll save some of the compounds that might be destroyed by a complete boil. (Still loss of enzymes, but what is there to digest anyways!)

    Then stems of plants are tougher still and might require boiling water or a longer simmer in pre-boil water.

    Roots, barks and all mushrooms (because of their tough cell walls) need a steady boil from anywhere from 5 minutes to 5 hours on a stove top.

    Hope that helps! 🙂

    “You don’t need to ask others if something is going to work for you; go ahead and give it a shot…give it 2 weeks.” advice ‘o the year.

  4. Jenn says:

    I personally enjoy herbal teas very much, but agree some are better with lower temperature water while some should be closer to boiled. Comes down to doing some research on getting the best medicinal value tea you drink.

    Lol, I like the Green Machine best but it makes me think of one of these( that were around when I was a kid. It was this or one of the original Big Wheels most kids had around me.

    Question for you. As you get ready for your big trip and go out to visit everyone, are you also going to do some sort of going away for those of us in CT that won’t end up seeing you for awhile when your on the road. A showing of the RV perhaps??

  5. Pixywinks says:

    Love the cat! More episodes with Johnny 5 please.

  6. DebB says:

    Oh ~ Great choices on your new RV’s names!

    I vote for Olive Oil (is that how it’s spelled?)

    I was also excited for you stating that you’re considering Portland, OR as a possible place to settle into when the time comes. We live 3.5 hours East and it just doesn’t get more beautiful than the Pacific Northwest! (This is said from a Chicagoan)

    Debbie *Ü*

  7. Hmmm….I like The Green Queen! Kale Whale is fun too haha:)

    I used to work at a tea room and we were very precise about the correct way to make tea. Our experience was that teas release the most flavor when boiling water is poured over them, and then steeped 4-8 minutes(longer for herbal teas, shorter for black teas). BUT the trick is to use really high quality water and to only bring the water ‘just’ to boiling-not letting it boil for a long time. So just to boil, take it off heat, and pour over tea.

    I was on a 100% raw diet for over 5 years, and now eat some cooked, just for fun, and because I was getting a little religious about it and decided that was not healthy. 🙂 SO now I am back to drinking tea(herbal) and my favorite is Good Earth Sweet & Spicy Original. Its wonderful! I like peppermint tea too….

  8. Ron says:

    Olive Oyl

  9. Oh P.S. I LOVE Portland. I have some family there. Its beautiful, you’ve got city and country, the ocean(Oregon Coast is gorgeous), trails and hiking and waterfalls all within 30 min-2 hrs, AND there is a great health community there.
    Definitely worth a visit.

  10. Andre says:

    My vote is: “Green Queen”

  11. DonnaB says:

    THE “KALE WHALE” sounds like the best of the four.

  12. lisa says:

    my vote is for kale whale! it so funny and cute!


  13. Bridey says:

    I don’t know if it is any better, but I’ll let seep a tea bag over night in room temp water and drink the tea the next day. Also sometimes I just make a warm tea instead of hot. I have nothing against hot tea though and would have no problem drinking it but when I perfer to make it the above ways. Maybe Bianca would like to do it that way as well if she is concerned.

  14. Roseanna says:

    I use the sun tea method for all my herbal teas, in a pinch I boil the water then let it cool sllightly, then add my tea bags-especially for white tea!

    A name for your R.V.- I vote on The Green Machine, although the selection/finals on this show was pretty weak. You had so many ,,,

    Love your show and thanks for all you do you two!!!

  15. Cheryl Holt says:

    I like Kale Whale although Olive Oil is very very CUTE…..
    It’s going to have to be The Kale Whale!

    : )


    They are planning a beautiful permaculture community in Sedona, AZ with community schools, shops, and such..I can send the face book group to you. What is not to love about Sedona AZ! Although the Oregon is beautiful.

  16. susan says:

    Hello Kevin enjoyed the show as usual , came away learning something new as well, I really enjoy your show , I cant wait to see what’s next. Take care of YOU.

  17. Ellen says:

    Please don’t use Green Machine as there is a juicer called that. Kale Whale would be my choice of the 4.
    Happy Travelling.

  18. elaina harman says:

    I just got an inspiration for a new name

    Oil to Toil for the Green Dream

  19. Yvette says:

    I like Olive Oil. Are you guys coming thru Denver, Colorado?

  20. momo says:

    well….i live near seattle and would love to have you two come visit sooooo since i suggested The Green Machine back when you asked, i will certainly vote for it today!
    happy trails..congrats about the steelers.
    when does The Green Machine take her maiden voyage?

    as for hot tea and such…i recently was told that ANY liquid over 170 degrees is acid forming and not optimally healthy and should be avoided…hmmm? not sure about that…what do you think?

  21. Blake says:

    Sometimes i leave the tea in cold water to soak overnight. That way in the morning it’s already part brewed and can be heated just to a nice warm temperature for drinking.
    My vote is for Kale Whale.

  22. ruth says:

    Green Queen, has a good feel to it, Have you done a numerology on the names? x

  23. Mandie says:

    I voted for Kale Whale even though I had also put in an entry on the youtube page for “Olive Oil” lol.

    By the way, is there any way to see how the voting is going? (Whose in the lead, etc).

  24. Sari says:

    Kale Whale!!! 😀 Sounds the best and it’s funny 🙂

  25. John in FL says:

    Kevin, I’ve been watching your show for appx 6 months and want to thank you for opening my mind in several important areas.

    The raw food ‘movement’ has made me curious but I remain unconvinced. Can you recommend a good book or other resource that offer a primer on the benefits of raw food?

  26. Margit says:

    i vote for Kale whale

  27. Deborah Gordon says:

    I vote for Kale Whale. hahaha

  28. Lynn says:

    I like The Kale Whale!! I was wondering if your kitty will be coming along for the ride across the country (I hope so, I’ve enjoyed seeing him on the show so much lately), and if not, who will you entrust him to?

  29. John says:

    Love the renegade health show updates. If you come to the UK let me know & I would like to hang out with you both.

    Re good workouts for the morning, try The 5 Tibetans, I have been doing these every morning for 12 years now, I’m 44 years old & I have a very toned & fit body. These exercises build your body from the inside out & massage all your tendons & ligaments & check this out, they only take 20 mins once you have built up to 21 repetitions. A perfect morning workout.

    In Light,


  30. RawLisa says:

    I love to pick fresh mint, sage and raspberry leaf from my garden and make tea. It is amazing, as the incredibly yummy volatile oils are still in the leaves when they are fresh and aren’t when they have been dried. Anyone can grow mint on their windowsill, try stopping it! My favourite mint for tea is Apple Mint, which has a slightly furry leaf.

    As for the name, well, although Green Machine is a good name, it is used quite a lot here in the UK, but perhaps not in the US. So my next favourite is Kale Whale. It certainly is original! I also love the promotion of greens! Greens are soooo great! I think kale needs more promotion and it is about time it got a look-in!

    Go well!

  31. Jennifer says:

    I like Olive Oil. 🙂

  32. ROB says:

    Portland, Oregon is AMAZING. It’s my goal in 2009 to move to Portland. I hope you love it as much as I do and decide to stay for a while. They have great farmers markets, great restaurants serving local food and great public transportation. I can’t wait to get rid of my car forever!!! Check out The Blossoming Lotus Restaurant while you’re there and try to get an interview with chef Mark Reinfeld. He is one of the authors of The Complete Idiots Guide to Eating Raw.

  33. Ram Govindaraj says:


    I am organizer of San Antonio Raw Food Food Meet up Group, I will assist you and provide accomodation if you come to San Antonio


  34. kali says:

    my “italian” vote has to be Olive “oil” Oyl ! : D

  35. donna says:

    oliveoil— Donna in the Keys

  36. martha says:

    kale whale – what a great name to promote curiosity and a sea veggie. If you go west coast you have to come east coast. I am near ECU and wouldn’t it be great to expose rawfoods where seaweed (kelp) is harvested as an industry.

  37. Donal. says:

    GREEN, for most people, means environmental, which though admirable and desirably, is not primarily “what you are about”.
    I vote for KALE WHALE.

  38. Carleen says:


  39. Chris says:

    What can one do to protect themselves from EMF’s while on the laptop computer all day while on a raw diet??/

  40. Ellen says:

    I vote for “Kale Whale”. You both seem to like that name because it makes you laugh. Laughter is great for health. It fits!

  41. Dawn says:

    I like Kale Whale too, it is so funny!
    An older Japanese lady told me once that the proper way to brew teas (herb or traditional) was to bring water to a boil then allow it to cool where there are no more bubbles before adding plant materials. It’s always worked well for me. Although I do make sun tea in the summer time also.

    Good news at my house, I got my 20yr old pizza-addicted son to try a raw smoothie with kale, spirulina, and home frozen blueberries 🙂 He loved it and is now a believer that the kale doesn’t affect the flavor. Ha, that means I can get raw greens in him, Yay!

  42. Almamater says:

    My favorite tea is matcha by Zenmatcha. Great stuff, and matcha is allegedly loaded with antioxidants. Does anyone else know of a quality matcha that’s less than $100 lb.?

  43. Monika says:

    LOL Kale Whale sounds cool :o)

  44. cathy warren says:

    HI! tough question,????i vote ;GREEN MACHINE
    [it was a toss up between that and olive oil,
    but i thought about it ,IT TRULY IS A CLEAN,GREEN ,MACHINE!

  45. becky ewing says:

    I like Kale Whale because it is very funny! I recall in an earlier episode you mentioned you are on the biotics Vita D supplement. I am on it too. I think more people should get their Vita D levels tested. I was extremely low – actually in the bone disease level low! Vita D regulates the immunity system and is very overlooked… I no longer wear sunscreen! Check out they are offering Vita D tests kits/results for only 30 dollars and are doing an important research study with some of the worlds top researchers on this very important subject…

  46. Kat says:

    How did you all ever pick 4 names out of so many great suggestions? I think Green Machine describes the RV the best, but it’s not cute or funny (sorry to whoever suggested it). I really love Kale Whale and Olive Oyl…

    I think I will have to vote for Kale Whale, since that’s the funniest one. 😀

    My favorite tea is Gen Mai Cha (green tea with toasted brown rice). Just below boiling water is suggested for steeping it (as with most teas); boiling water (or too much steeping time) usually makes tea bitter.

    I love that Johnny Five is getting more airtime lately – what a cutie pie! 🙂 Just wondering, is there a significance to his name (and number)?

  47. Margie says:

    My vote: Green Queen : )

  48. Bette says:

    OH well. I dont like any of the four..My vote on those however….The Green Machine.Its the only one that speaks anywhere near your message.

  49. Connie says:

    Kale Whale
    Olive Oil
    Green Machine
    and… what was the 4th one? (They should be listed where we can see them.)

    I don’t really like any of these choices–I was hoping you’d go for some of the Rawkin-xxx names, like Rawkin-Rollin or something. Anyway, of these four I guess I like Kale Whale best.

  50. Sue Rushford says:

    I just really like The Green Machine, but I’m not so sure how appropriate a name that would be for a necessarily gas-guzzling vehicle, even if it is ‘green’ gas. Green Queen doesn’t do it for me – better for a boat. Kale Whale and Olive Oil are both cool. I guess I’ll have to go with Kale Whale cause it is the size of a whale, and there will likely be lots of kale around.

  51. Patricia A'amina says:

    Well… I’m not crazy about any of them… but since vehicles usually have female names, I vote for Olive Oil.

  52. Christopher says:

    I’m voting Kale Whale (I’m a little biased), but I think any of those names would be great.

    On the tea subject, I use to drink a lot of tea, especially adaptogens, to help with energy. Since I’ve been mostly raw , however, I haven’t been drinking any tea. After watching today’s video, I am thinking about adding some in again, as I think the benefits of drinking tea outweigh the negatives (heating).

  53. Chel says:

    Kale Whale rocks!

    Tea is the only thing I consume that is cooked. I am interested in brewing it using only the sun. On top of all the health benefits of the tea itself you get extra sun energy! I’m going out to run errands right now, I think I may pick up a few big sun tea containers.

    Groovy show guys!

    Oh, and I have a question too…What do you think of urine therapy? I think you may have put that on your “top ten weirdest health practices” show…I was researching last night and there is this whole big crazy urine therapy community! What’s your take?

  54. Gail says:

    Green Machine

  55. gloria says:

    I also vote for Kale Whale.
    As for my teas, I heat the water up to just before the boiling point, as soon as I see the first bubble, I turn it off.
    Johnny V is very handsome! How is the leash training going?
    You should leave the harness on just for few minutes at a time, every day, without putting the leash, just so he gets used to having something on him, then once he is used to it, try with the leash and see if he walks.
    Good luck on your wonderful adventure

  56. Toni says:

    Kale Whale

    I put my herbal mixture in a glass jar and let it sit in the window sill 24 hours. I then strain the tea/ herbs, drink the liquid and put the now wet tea/ herbs in a glass and add hot water and then drink that tea. I try to get the most use possible out of the tea/ herbs.

  57. Jos says:

    I vote for Kale Whale!

  58. Rhonda says:

    Hi Kevin and Annmarie,

    I love hot tea. I boil and steep for 3 or 4 minutes, the old English way. I am quite sure it brings out the medicinal properties of the tea and it is so delish.

    You asked if we are in agreement to 100% raw. My opinion based on years of nutrition study, is that it is great to have a lot of raw foods in the diet but to go 100% is too extreme. You miss out on the benefits of many cooked foods that do have their nutrients even though cooked. With the amount you two consume raw through various meals, snacks and juices, I am confident you are gaining all the benefits from the raw foods and that having a percentage of other or cooked foods would be fine. Life is more doable in moderation verses extreme. Hard to maintain realistically.

    Hi Johnny Five, he is a beauty.

    Take care, and visit us in Colorado when you are on your way to Oregon. You may be really surprised at what Colorado offers.



  59. Vita says:

    l vote for Olive Oil (Oyl) 😉

    As for tea, l bring it just to the boil, take it off the heat and put the herbs in the teapot, then pour the water in, and cover it with a tea cozy. lt stays warm for hours this way.

    l especially like stinging nettle tea, sometimes with different varieties of mint, sometimes with a bit of green tea.

  60. Carol says:

    I vote for Kale Whale.

  61. Diana says:

    VOte for Kale WHale

  62. Valerie says:

    Hey,.. can I suggest another name?..
    “The Catalyst”
    (chemistry) a substance that initiates or accelerates a chemical reaction without itself being affected
    something that causes an important event to happen; “the invasion acted as a catalyst to unite the country”
    if anything is what you guys are about it is that… and it’s almost has like a cadillac sound in it….
    anyway,.. I know it’s voting time… but well,.. all’s fair in Love and naming vegie oil RV’s that are touring across the country… !
    come visit Florida!

  63. Diane Williams says:

    And I like Rawkin-Rollin also! otherwise, Kale Whale. When do you come to Austin, TX?

  64. Margaret - LA, CA says:

    Definitely Kale Whale! Love it. I also really enjoy your episodes, especially the cooking ones.

    thanks for all the info.

  65. Margie says:

    I vote for “The Green Machine”! It was one of my suggestions but would be surprised if I was the only one.

  66. Karen says:

    I vote Kale Whale – a perfect Northwest name! I live 60 miles east of Portland in Hood River – if you come via I-84 stop by, my 3 year old makes a mean green juice! Portland is a great city for raw living – long growing season, year round farmer’s markets, lots of neighborhoods full of personality and local flavor.

  67. Karen says:

    None of the “Final 4” names chosen are fitting for the amazing crusade that you two are journeying on. I hope you discover a more inspiring moniker that succinctly expresses what you are about!

    Your cat is beautiful! He looks like grey velvet. What is his age . . . have you had him since a kitten? I am glad you are including him in your journey since he considers you his family.

    Blessings and Great Health to You Both!!

  68. Mike Layer says:

    I vote for green machine.

  69. stella Morris says:

    Of the four, kale whale but Catalyst now that says it all…

  70. Traci says:

    I’m sorry, I didn’t really like any of those. I thought of “Renegade Roadster” because of your Renegade Health Show. I love your show.

  71. Bobbie says:

    Vote 1 Kale Whale
    Vote 2 Kale Whale (my husband)
    Vote 3 Kale Whale (my Mum)
    Vote 4 Kale Whale (brother)
    Vote 5 Kale Whale (siister in law)
    Vote 6 Kale Whale ( niece)

    Hands down.

    If you all make a tour through the south, you’ve gotta come by and visit us in Oklahoma. There is lots of agriculture and cheap land but no raw community. The only place to get organic veggies in Durant is Walmart. They do have a farmers market in the summer time.

    I have to say that I’ve watched some of the excercize videos posted here and I’ve been doing the upper body stretching at work and they greatly relieve back tension. I never realized how simply stretching can get your chi moving in the right direction. 🙂 I mean I have really experienced a quality of life change here. Thank you!

    I’ll drink any kind of tea. I don’t mind the tastes being different or strong. I get a real satisfaction when I drink it. I always have tea leaves soaking overnight and all day. I don’t fridge it or heat it after it infused and I just drink it room temperature. I think it releases the minerals the best. I’ve heard herbal teas are supposed to be used medicinally, but I will make infusions with any tea herb I come across. I haven’t noticed any bad effects, only good ones. If it’s nettle tea, I’ll even put the exhausted herbs in my salad. I carry glass bottles full of tea with, tea leaves soaking in it, to work with me. I use those Kombucha bottles. They are great bottles I reuse them over and over and their lids are good too. I am very careful as I’ve only broken one bottle. I kind of stick out like a sore thumb at work because everybody asks me what I’m drinking. You could say I like to milk my tea bags for what they’re worth. As far as tea goes, you can have tea, I’ll have an infusion.

  72. Joseph says:

    I would of named the RV after your fur kid Johnny 5

    Me with tea I did not drink it when I first started on the raw adventure. Just in the past week I reintroduced myself to tea. Gotta say I missed in it in the past few months.
    Now that I am working on balance in my life I figured the tea was a welcom addition.

  73. Ann says:

    Rawkin-Rollin definitely. The others are very predictable and sort of plain. That’s just my opinion, lol. As far a as raw food goes, I incorporate plenty of it in my daily diet. But, do not think I would ever go completely raw. Think about this, man created fire and learned to cook with it among other things. It’s a part of human life and nature. I think some foods should be cooked. Slightly cooked broccoli and tomatoes actually bring out more nutrients than if they were eaten raw. That has to mean something…

  74. Ladan says:

    How about “Greens on Wheels”…if not then i pick olive oil…Johnny 5 rocks! he should have his own talk show 😉

  75. ida margrethe says:

    im glad you ended up with the Kale Whale, its a rad name!
    And about the tea. I LOVE tea and i tend to drink way too much of it – its like an addiction.. im addicted to cooked food! hah. that reminds me of that ‘Natures First Law’ book where every chapter ends with the phrase cooked food is poison.

    Anyway, I usually drink fruity or blossomy (?) sencha teas, and herbal teas and also yerba mate. Never heat my water over 70’C, stop way before that. Its just easier and better and the flavours get to really do their thing.
