  • 0:00 - 0:03
    So, my name is Ryan, I'm, live in Palo
  • 0:03 - 0:06
    Alto, but I'm from Maryland and I am lactose intolerant.
  • 0:06 - 0:08
    >> For everybody out there, who doesn't know what lactose
  • 0:08 - 0:12
    intolerance is, tell us briefly what being lactose intolerant means.
  • 0:12 - 0:15
    >> in briefly, it means I can't have
  • 0:15 - 0:19
    milk or other dairy products without experiencing some discomfort.
  • 0:19 - 0:20
    [INAUDIBLE]
  • 0:20 - 0:23
    >> I see. Discomfort and can you elaborate a little bit on discomfort?
  • 0:23 - 0:27
    >> Sure. discomfort typically means it's digestive discomfort.
  • 0:27 - 0:31
    So it's gas, bloating, diarrhea, that sort of thing.
  • 0:31 - 0:34
    >> is anyone else in your family lactose intolerant?
  • 0:34 - 0:35
    >> Yes, my younger sister is, but I have
  • 0:35 - 0:38
    a brother who is not and my parents are not.
  • 0:38 - 0:45
    >> Okay so do you, do you have any experience with this being a genetic trait?
  • 0:45 - 0:49
    Like do, does this run in your family, being lactose intolerant?
  • 0:49 - 0:51
    >> I actually don't know because most of my family lives in the
  • 0:51 - 0:53
    Philippines and they don't drink cow milk.
  • 0:53 - 0:55
    They have, they drink powdered milk and
  • 0:55 - 0:59
    all this and not dairy products. Because it's not as popular there, so it
  • 0:59 - 1:01
    wasn't until I discovered I was lactose
  • 1:01 - 1:04
    intolerant that I learned anything about it.
  • 1:04 - 1:06
    >> And when did you discover that you were lactose intolerant?
  • 1:06 - 1:10
    >> I would say that would be about two or three years ago. So.
  • 1:10 - 1:11
    >> Really? That
  • 1:11 - 1:12
    late in life, huh?
  • 1:12 - 1:15
    >> Yes. But then when I found I was lactose
  • 1:15 - 1:17
    intolerant, it kind of explained some things from when I was
  • 1:17 - 1:21
    younger. because there were times like, when I would have
  • 1:21 - 1:23
    dairy products and I'd be fine, but then there were times
  • 1:23 - 1:25
    if I had too much, I'd felt, I felt a
  • 1:25 - 1:28
    little gassy. But when I discovered I was lactose intolerant, it
  • 1:28 - 1:31
    kind of made sense that if I was young and overloaded
  • 1:31 - 1:34
    on it, it made sense that, that I would feel discomfort.
  • 1:34 - 1:36
    >> I see so when you were young though, you felt like you
  • 1:36 - 1:38
    could have normal amounts and you were okay.
  • 1:38 - 1:41
    >> Mm-hm. Right. It wasn't until graduate school. Until, yeah
  • 1:41 - 1:43
    about two years ago, that I discovered that I was
  • 1:43 - 1:46
    lactose intolerant. And I think it's because that's when it
  • 1:46 - 1:48
    kind of just, when it really just kind of shut off.
  • 1:48 - 1:50
    >> Right, right. How did that make you
  • 1:50 - 1:52
    feel to sort of discover this about yourself?
  • 1:52 - 1:54
    >> Well, I guess that it kind of made
  • 1:54 - 1:57
    sense to me because I, it explained a lot
  • 1:57 - 1:59
    of things about why I'd randomly feel sick some
  • 1:59 - 2:02
    days. And why I wouldn't other days, just depending
  • 2:02 - 2:06
    on my breakfast. But, it was kind of annoying to find out
  • 2:06 - 2:10
    mostly, because I knew I'd have to either change my diet or.
  • 2:10 - 2:10
    >> Right.
  • 2:10 - 2:11
    >> Other things also
  • 2:11 - 2:12
    >> So, what are the kinds of food you actually
  • 2:12 - 2:15
    have to avoid if you are a lactose intolerant person?
  • 2:15 - 2:18
    >> if you are lactose intolerant and you're not
  • 2:18 - 2:20
    taking any type of supplement. Then you basically have
  • 2:20 - 2:24
    to avoid anything that has appreciable amount of dairy
  • 2:24 - 2:27
    products in it. So, obviously I'm not going to to be
  • 2:27 - 2:32
    drinking a lot of straight milk, ice cream, pizzas with a lot of cheese on it.
  • 2:33 - 2:38
    taco, taco, American-style tacos, oreos, all those things, cake, cheesecake.
  • 2:38 - 2:42
    >> so what you're saying is that there's a lot of food restrictions?
  • 2:42 - 2:47
    >> Yes, it is there's a lot, a huge part of the diet that is, has diary
  • 2:47 - 2:52
    products in it. And so discovering lactose intolerant kind of, makes it more
  • 2:52 - 2:54
    difficult to get that so.
  • 2:54 - 2:56
    >> So do you find yourself in situations, I
  • 2:56 - 2:58
    guess social situations where you see a food come
  • 2:58 - 3:00
    out and you're like oh gosh, I really want
  • 3:00 - 3:02
    that. And you're like oh gosh I can't eat it
  • 3:02 - 3:07
    >> Yes. especially I do, I do try to carry around lactase
  • 3:07 - 3:11
    pills lactase enzyme pills, but if I don't have them then yes.
  • 3:11 - 3:14
    If someone's like. Let's go out for ice cream. I go, oh,
  • 3:14 - 3:17
    I guess I can't. Or you know. Or if there's pizza. Especially if
  • 3:17 - 3:20
    people you know, at the last minute want to get
  • 3:20 - 3:22
    pizza or certain, go out for dinner and we haven't
  • 3:22 - 3:25
    decided. If they suggest pizza, I got, I have
  • 3:25 - 3:27
    to go, oh, I don't, I can't really eat that.
  • 3:27 - 3:29
    >> Are people receptive to this when you tell them, like
  • 3:29 - 3:31
    if you tell a group of friends or even new people. Like
  • 3:31 - 3:33
    hey, I'm lactose intolerant, you know, can, you know, can we
  • 3:33 - 3:36
    do something else, can we get something else? Are people normally receptive?
  • 3:36 - 3:40
    >> Yes. especially in California actually, because in California
  • 3:40 - 3:43
    a lot of people are, know people with various
  • 3:43 - 3:48
    dietary restrictions or go on different diets and so. It's definitely, it hasn't
  • 3:48 - 3:51
    really effected my social life. It just means that we do something else.
  • 3:51 - 3:55
    >> You mentioned lactase pills. What exactly is a lactase
  • 3:55 - 3:57
    pill? Where do you get it? How much does it cost?
  • 3:57 - 4:02
    >> A lactase pill is just a little pill about a little less than an inch big,
  • 4:02 - 4:08
    by a quarter inch, that is just a number of units of lactase enzyme. So lactose
  • 4:08 - 4:11
    intolerant means my body doesn't produce lactose any more, which is
  • 4:11 - 4:15
    the enzyme that breaks down the lactose sugar into two different
  • 4:15 - 4:18
    sugars. So this pill I eat it, I always buy the
  • 4:18 - 4:20
    fast act pill, so I can just eat it with my first
  • 4:20 - 4:24
    bite of food and it kind of dissolves. And has to break
  • 4:24 - 4:26
    down all the sugars in my stomach. And so I take
  • 4:26 - 4:29
    that with my first bit of dairy and then I'm usually
  • 4:29 - 4:33
    good for about 45 minutes before I have to take another one.
  • 4:33 - 4:34
    >> Well how much do they cost?
  • 4:34 - 4:37
    >> I would say it's about $0.10 a pill. So
  • 4:37 - 4:42
    120 would be about $12 to $13 at Safeway, for example.
  • 4:42 - 4:46
    >> is this a trait you would ever want to change about yourself at all?
  • 4:46 - 4:50
    >> Definitely. I just feel I mean, being lactose intolerant just means,
  • 4:50 - 4:52
    I can live my same life and eat the same amount of. Eat
  • 4:52 - 4:55
    the same foods and do the same things I want to. But I
  • 4:55 - 4:58
    just have to spend more money to do it, because I buy the
  • 4:58 - 4:59
    lactase, lactose free milk and I buy
  • 4:59 - 5:02
    the lactase pills to supplement other meals.
  • 5:02 - 5:04
    >> Have you ever gotten your own personal
  • 5:04 - 5:07
    genetic information done from a company like 23andMe?
  • 5:07 - 5:09
    >> Yes I have.
  • 5:09 - 5:11
    >> And did, what did that tell you about
  • 5:11 - 5:13
    you being lactose intolerant? Did it confirm this or?
  • 5:13 - 5:18
    >> it confirmed I have the geno-type that is likely lactose
  • 5:18 - 5:21
    intolerant. Because since lactose intolerant
  • 5:21 - 5:23
    can also depend on environmental factors,
  • 5:23 - 5:27
    like your actual gut bacteria that breaks down the lactose.
  • 5:27 - 5:30
    It means I have the tendency to be lactose intolerant, but
  • 5:30 - 5:32
    it doesn't mean I am. The only way you can confirm
  • 5:32 - 5:36
    that you are is to kind of know that you are.
  • 5:36 - 5:39
    >> What would you say if you could give advice to
  • 5:39 - 5:42
    somebody who is, let's say we're talking to Ryan three years
  • 5:42 - 5:44
    ago before he found out he was lactose intolerant. And he,
  • 5:44 - 5:48
    you know, just discovered that you're lactose intolerant, what advice would
  • 5:48 - 5:49
    you give that person?
  • 5:49 - 5:51
    >> I think the first advice would be to
  • 5:51 - 5:54
    test your limits on lactose tolerance. So I can have
  • 5:54 - 5:57
    a bite of ice cream, or one nacho with cheese,
  • 5:57 - 6:00
    or, but then won't bother. So, like, knowing your limit
  • 6:00 - 6:03
    on what you can have without any kind of supplement
  • 6:03 - 6:08
    is useful. And also to just make the decision whether
  • 6:08 - 6:10
    you're going to change your diet or buy the pills,
  • 6:10 - 6:13
    or some kind of combination of both. Just kind of,
  • 6:14 - 6:20
    figure it out. Or I'm looking to lactose free alternatives
  • 6:20 - 6:24
    to milk, or they even have lactose free ice cream now, but it's very expensive.
  • 6:24 - 6:25
    >> Sure.
  • 6:25 - 6:28
    >> So it's like Is it worth it to buy the ice cream? So you
  • 6:28 - 6:30
    don't have to take pills, or do you want to take pills every single time you
  • 6:30 - 6:35
    eat ice cream, sort of thing. It's kind of just, decide all the different ways
  • 6:35 - 6:39
    to manage your lactose intolerance and figure out which way is the best for you.
  • 6:39 - 6:41
    >> Well, thank you for coming in and chatting with us.
  • 6:41 - 6:44
    >> Yeah thanks for talking with me, I don't get to talk about this that often.
  • 6:44 - 6:44
    [LAUGH].
