Is A Vegan Diet Vitamin D Deficient? | Dr Michael Greger of Nutritionfacts.org

  • 0:00 - 0:06
    Where do vegans like me get our vitamin
    D? Well, from the sun, of course. I mean c’mon.
  • 0:07 - 0:12
    Can’t you tell? Can you? Probably not…
  • 0:16 - 0:22
    Hi it’s Emily from Bite Size Vegan and welcome
    to another vegan nugget. Vitamin D is of course
  • 0:22 - 0:27
    associate with the sun, but with estimates
    of around 70% of the population being deficient,
  • 0:27 - 0:32
    we’re apparently not getting the exposure
    we require. Now this is an oversimplification
  • 0:32 - 0:39
    of the matter as vitamin D comes in two basic
    forms: D2 and D3. D2 is present in vegetables
  • 0:39 - 0:44
    and various supplements and D3 is mainly formed
    from our skin’s exposure to the sun.
  • 0:44 - 0:50
    But is also present in a variety of animal products,
    like fatty fish and their oils, beef liver,
  • 0:50 - 0:56
    egg yolks, and fortified dairy and grain products.
    The fortified products, however, have marginal
  • 0:56 - 1:01
    levels for the most part, and are not well
    regulated. So what’s a vegan, particularly
  • 1:01 - 1:06
    a vegan in non-tropical climates, to do? Well,
    in this fifth video in my nutrient series
  • 1:06 - 1:10
    with nutrition powerhouse Dr. Michael Greger
    of Nutritionfacts.org,
  • 1:10 - 1:12
    We’ll tackled the vitamin D debacle.
  • 1:13 - 1:18
    Could you talk a little bit about Vitamin-D
    in, you know, a plant based diet. Where are
  • 1:18 - 1:22
    we getting it...Is it beyond just exposing
    yourself to the sun and how does all of that work?
  • 1:23 - 1:27
    So, Vitamin-D is the sunshine
    vitamin. It’s actually not a vitamin but
  • 1:27 - 1:32
    a hormone...our skin makes when it’s exposed
    to sunlight. Of course, depends on where you
  • 1:32 - 1:37
    live on the planet. We evolved running around,
    you know, naked in equatorial Africa getting
  • 1:37 - 1:43
    baked in the sun all day. We just weren’t
    meant to live at such latitudes where during
  • 1:43 - 1:47
    the winter months, up in Boston for example,
    January, February, no matter how much you
  • 1:47 - 1:52
    sunbathe naked on the commons, you are not
    going to make enough Vitamin-D. Now, there
  • 1:52 - 1:59
    are some Vitamin-D you made in the summer
    that will be stored in your fat, and so you...
  • 1:59 - 2:04
    ...but your levels will dip below which we believe
    is optimal. So, particularly during the winter
  • 2:04 - 2:10
    months or anytime during the year for people
    not getting enough mid-day sun, and for white
  • 2:10 - 2:17
    enough people at low enough latitudes, you
    know, 5 minutes forearms and face...
  • 2:18 - 2:26
    ...can be enough mid-day sun. But, particularly at higher
    latitudes with darker skin, people that are
  • 2:26 - 2:33
    older, or those that have jobs and they’re
    inside all day, no matter how sunny it is
  • 2:33 - 2:38
    outside, should get their Vitamin-D from Vitamin-D
    supplements. So, I recommend for people not
  • 2:38 - 2:46
    getting enough mid-day sun to take...2,000
    International Units (IU) of Vitamin-D a day which is what I do.
  • 2:46 - 2:50
    Do you know, are there any Vitamin-D
    supplements that you are aware of that don’t
  • 2:50 - 2:53
    have their source from Lanolin or any sheep
    sources?
  • 2:53 - 2:59
    Oh yeah, so all D2 sources come
    from fungi; from mushrooms, and there are
  • 2:59 - 3:05
    now plant based sources of D3 which are made
    from lichen. And the studies showing that
  • 3:06 - 3:12
    Vitamin-D, optimal Vitamin-D levels associated
    with longer life have come from Vitamin-D3
  • 3:12 - 3:17
    studies, so I encourage people, eh...that
    D3 is better just because we have data there.
  • 3:17 - 3:21
    So, you can get plant based or animal based
    D3 just as easily.
  • 3:22 - 3:27
    I hope you enjoyed hearing from Dr. Greger
    on this matter. Just to note, Vitamin D is
  • 3:27 - 3:31
    essential for bone health as it helps calcium
    get from our intestines to our bones.
  • 3:32 - 3:37
    You can find out all about calcium in a vegan
    diet in this video. It also helps with muscle
  • 3:37 - 3:42
    function and is associated with lower risks
    of breast and colon cancer. Vitamin D may
  • 3:42 - 3:46
    also play a role in mood stabilization and
    fighting depression.
  • 3:46 - 3:51
    As Dr. Greger said, depending on where your
    live, and even your body’s individual absorption
  • 3:51 - 3:57
    issues, you may not be getting adequate vitamin
    D, regardless of your diet. We were intended
  • 3:57 - 4:02
    to get our D from the sun but as most of us
    are no longer running around naked in the
  • 4:02 - 4:07
    tropical sun and feeling the rays lap our skin
    with their warm embrace.
  • 4:13 - 4:15
    Well, this is...awkward.
  • 4:18 - 4:23
    There are areas of the world where sun-based
    vitamin D is simply not available for long
  • 4:23 - 4:28
    stretches of time. Dietarally, there now exists
    UV-exposed mushrooms that contain vitamin D
  • 4:29 - 4:33
    Mushrooms naturally produce and store the
    vitamin when exposed to sunlight, but don’t
  • 4:33 - 4:38
    tend to grow in sunlight, so farmers have
    taken to briefly exposing harvested mushrooms
  • 4:38 - 4:44
    to UV light. This can also be accomplished
    by leaving them in the sun, however then...
  • 4:44 - 4:46
    ...they shrivel up.
  • 4:50 - 4:50
    Eww!
  • 4:52 - 4:53
    No..Eww!
  • 4:53 - 4:57
    So, if you want to supplement, how do you
    ensure the sources are vegan? Well, D2 is
  • 4:57 - 5:03
    always vegan, as it’s a plant-based source,
    but D3, which is commonly used in supplements
  • 5:03 - 5:09
    and vitamin D fortified grains, juices, and
    other products, comes from lanolin, which
  • 5:09 - 5:10
    is derived from sheep’s wool.
  • 5:10 - 5:15
    Now if you’re thinking “what’s the big
    deal? It’s not like sheep are dying for
  • 5:15 - 5:19
    their wool". Please see my video on whether
    wool is vegan. Up until more recent years,
  • 5:19 - 5:24
    there were no vegan vitamin D3 supplements.
    However, now there are several brands of vegan
  • 5:24 - 5:27
    D3 on the market, derived from lichen.
  • 5:27 - 5:32
    I have links to the vegan D3 supplements and further
    reading in the blog post for this video, which
  • 5:32 - 5:37
    is linked in the video description below and in
    the infocard sidebar. Now I personally don’t eat any
  • 5:37 - 5:41
    fortified foods so when I enter my food intake into Cronometer,
  • 5:41 - 5:45
    my vitamin D always looks,
    kind of sad. But, I am sure to expose myself
  • 5:45 - 5:50
    to sunlight regularly and, when living in
    less friendly climates, I will supplement with vegan options.
  • 5:51 - 5:57
    Now, a word of caution- you can take too many vitamin
    D supplements, resulting in high blood calcium
  • 5:57 - 6:02
    levels, which can lead to nausea, constipation,
    confusion, abnormal heart rhythm, and even
  • 6:02 - 6:06
    kidney stones. So please stay within doctor-recommended
    doses.
  • 6:07 - 6:13
    So, to track your own vitamin D, check out
    Cronometer. You can enter your meals and activity
  • 6:13 - 6:16
    to make sure you’re right where you want
    to be. You can even go and create your own
  • 6:16 - 6:21
    food, select supplement and enter the data
    for the supplement you take. Then, in your
  • 6:21 - 6:26
    day’s nutrition report, you can have the option
    of showing or hiding your supplements to see
  • 6:26 - 6:31
    where your diet alone measures up. Pretty
    freakin’ cool, right? So cool that they’re
  • 6:31 - 6:36
    actually sponsoring this video to get this
    information out. And the best part?
  • 6:36 - 6:41

    option on there and kind of had a nerdgasm.
  • 6:52 - 6:53
    Too much?
  • 6:54 - 6:59

    These are actually the sunglasses I wear...they go over glasses.
  • 7:50 - 7:53
    Cause I'm to cheap to get a prescription, so.
  • 7:54 - 7:57
    Rock it out like an old lady who just got her eyes dilated.
