Latest / Stuff You Should Know / Short Stuff: All about BPAs
Transcript
- 0:04Speaker 1: Hey, and welcome to the short stuff. I'm Josh, and
- 0:06Speaker 1: there's Chuck and Jerry sitting in for a day. So
- 0:08Speaker 1: this is short stuff about the beware of the pas.
- 0:15Speaker 2: That's right.
- 0:15Speaker 3: We're talking about BPAs specifically, well BPA, which is how
- 0:21Speaker 3: do you pronounce that.
- 0:22Speaker 1: Josh, I'm going with this phenol or bisphenol.
- 0:25Speaker 2: Hey, bisphenol A.
- 0:26Speaker 3: There are other bisphenols apparently which I didn't know, and
- 0:30Speaker 3: apparently you know.
- 0:31Speaker 2: None of these are good.
- 0:32Speaker 3: For you, even though the FDA is like, it's fine
- 0:35Speaker 3: in the amounts that you're getting it.
- 0:37Speaker 1: Stop being so uptight, everybody. Yeah, they're used in all
- 0:43Speaker 1: sorts of plastics, polycarbonate in particular. But that stuff shows
- 0:46Speaker 1: up everywhere. It can be in the stuff that lines
- 0:50Speaker 1: tin cans, it can be in your dental work, it
- 0:53Speaker 1: can be in contact lens, storage containers, baby bottles used
- 1:00Speaker 1: to be. I don't think it is anymore, but it
- 1:03Speaker 1: was everywhere. It's also now still today. The greatest exposure
- 1:07Speaker 1: that people get on average is from holding receipts thermal
- 1:10Speaker 1: paper receipts.
- 1:12Speaker 2: Oh interesting, those.
- 1:13Speaker 1: Are coded with BPA, so just be aware of that.
- 1:16Speaker 1: I saw a study that said just holding one for
- 1:19Speaker 1: ten seconds exposed you to unsafe levels of BPA.
- 1:23Speaker 3: You know, many years ago when we lived in Los Angeles,
- 1:26Speaker 3: And it's the jokes Emily still laughs at to this
- 1:28Speaker 3: day because it's just very me very sardonically. Chuck was
- 1:33Speaker 3: we left a Blockbuster video and it was like Princh, Princh,
- 1:38Speaker 3: and they did that thing where there was a ticker
- 1:40Speaker 3: tape of like three feet of receipts each you know,
- 1:43Speaker 3: connected by a little tiny piece of paper, and he
- 1:45Speaker 3: handed them to me and I just went, thank you
- 1:47Speaker 3: for the receipts. And Emily thought that was the funniest
- 1:50Speaker 3: thing ever, and she still says.
- 1:52Speaker 2: It to this day.
- 1:54Speaker 1: Yeah, I could see being in the right place, in
- 1:56Speaker 1: the right frame of mind and just finding that awesome.
- 1:59Speaker 3: Yeah, really stoned at Blockbuster.
- 2:02Speaker 1: Sure do you remember when you rented?
- 2:06Speaker 2: Oh no, no, no, who knows.
- 2:08Speaker 3: But now that I don't feel so bad now that
- 2:10Speaker 3: I know that those things are loaded with BPAs.
- 2:12Speaker 2: I don't want those in my pocket.
- 2:14Speaker 1: No, you don't. And the reason why we're even like
- 2:16Speaker 1: talking about BPA is all thanks to a geneticist named
- 2:20Speaker 1: doctor Patricia Hunt, who was studying the ovaries of mice
- 2:25Speaker 1: back in the late nineties, nineteen ninety eight. That was
- 2:28Speaker 1: her jam. She was not looking for BPA, she was
- 2:31Speaker 1: not studying BPA at all, but BPA came and found her.
- 2:35Speaker 3: Essentially, Yeah, she saw these chromosotal errors start popping up.
- 2:40Speaker 3: They went from two percent to forty percent in these
- 2:43Speaker 3: mice that she was studying in the control group, and
- 2:46Speaker 3: that you know, there was miscarriage, there were birth effects
- 2:49Speaker 3: in these little baby mice. It's all very sad. And
- 2:52Speaker 3: she ran some more tests and she was like, you
- 2:53Speaker 3: know what, all of these cages and water bottles that
- 2:58Speaker 3: these mice are drinking out of have BPA in them,
- 3:01Speaker 3: and I think that's where it's coming from. So she
- 3:03Speaker 3: swapped that stuff out with non BPA stuff. Everything returned
- 3:07Speaker 3: to normal, and she was like, I think I found
- 3:10Speaker 3: something really bad here.
- 3:11Speaker 2: Everybody, Yeah, she did.
- 3:13Speaker 1: She also really started to examine what BPA did. Disrupted
- 3:18Speaker 1: fetal development. The eggs of the fetus that had its
- 3:22Speaker 1: development disrupted, that fetus's eventual babies those were also disrupted
- 3:28Speaker 1: as well. So yeah, she was like, I think something
- 3:31Speaker 1: is really bad here. And what she turned up is
- 3:33Speaker 1: that BPA acts as an endocrine disruptor, meaning it mimics
- 3:38Speaker 1: a hormone in our body, which does all sorts of
- 3:42Speaker 1: stuff because our hormones are very very well precisely timed,
- 3:46Speaker 1: and you go over here and do this, you go
- 3:47Speaker 1: over here and do that. And if something shows up
- 3:50Speaker 1: on mass and is like we're gonna do all of
- 3:52Speaker 1: this at once, there's all sorts of catastrophic things that
- 3:55Speaker 1: can happen to the human body.
- 3:57Speaker 2: Yeah, for sure.
- 3:58Speaker 3: And in this case, in the case of BPA, what
- 4:00Speaker 3: it really does is affect estrogen, and estrogen has a
- 4:04Speaker 3: huge effect on a lot of stuff. I think it
- 4:06Speaker 3: can affect the behavior of more than two hundred genes
- 4:10Speaker 3: and almost every organ and tissue in the body can
- 4:14Speaker 3: be affected by estrogen. So this was a big deal
- 4:18Speaker 3: at the time. There were a lot of initial reactions
- 4:21Speaker 3: of like, you know, we're not sure how bad this stuff.
- 4:25Speaker 2: Is for you.
- 4:27Speaker 3: We're not going to do anything right now, Like the
- 4:29Speaker 3: evidence is like not really conclusive because we're not mice
- 4:33Speaker 3: and so we're not necessarily going to experience the same
- 4:36Speaker 3: health effects. And again these limits are like the amount
- 4:40Speaker 3: that we're getting shouldn't harm it, Like, you know, children
- 4:44Speaker 3: and adults.
- 4:44Speaker 1: Right, that was wrong. It turns out that the limits
- 4:49Speaker 1: that we were being exposed to were considered harm or
- 4:52Speaker 1: are considered very harmful. Now, but what's something weird, Just
- 4:57Speaker 1: a little thing to kind of put aside. It actually
- 4:59Speaker 1: turns out that low doses of BPA have worse effects
- 5:02Speaker 1: than larger doses of BPA.
- 5:04Speaker 2: Yeah, that's weird.
- 5:04Speaker 1: I didn't see anywhere that that was explained, so I
- 5:08Speaker 1: came up with my own explanation. It's three stooges syndrome,
- 5:12Speaker 1: which is how remember mister Burns had every disease, but
- 5:15Speaker 1: none of them were affecting them because they were all
- 5:17Speaker 1: trying to get through the same door at once. I
- 5:20Speaker 1: think that's what happens when you have a bunch of BPA.
- 5:22Speaker 1: They all get stuck trying to get through the same
- 5:25Speaker 1: door at the same time, and it doesn't affect you
- 5:27Speaker 1: like a little bit does, which can make it right
- 5:29Speaker 1: through the door.
- 5:30Speaker 3: All right, doctor Clark, We're going to take a break
- 5:32Speaker 3: and ponder that, and we'll be right back with more
- 5:34Speaker 3: on BPAs.
- 5:56Speaker 2: I gotta say I'm very impressed.
- 5:58Speaker 1: Thank you, But I feel like I should say I
- 6:00Speaker 1: am not a doctor, and you really shouldn't listen to
- 6:02Speaker 1: me with any medical stuff. Whatsoever.
- 6:05Speaker 2: But I called you a doctor.
- 6:06Speaker 1: Oh well, then I'm a doctor.
- 6:09Speaker 2: All right.
- 6:09Speaker 3: So, in the United States, the FDAs, who was in
- 6:13Speaker 3: charge of regulating the BPA use, and in twenty ten
- 6:17Speaker 3: they did a four year review of BPA studies which
- 6:20Speaker 3: resulted in twenty fourteen.
- 6:23Speaker 2: Basically saying, you know what.
- 6:26Speaker 3: We're upholding our previous no observed adverse effects level label.
- 6:31Speaker 3: As long as you don't get more than five milligrams
- 6:35Speaker 3: of body weight per kilogram of body weight per day,
- 6:38Speaker 3: you'll be fine.
- 6:40Speaker 1: Yeah, And I think that that is a level that
- 6:42Speaker 1: most people are never exposed to, right.
- 6:45Speaker 2: Well, that's what they say.
- 6:46Speaker 3: I mean, we should talk about some of the things though,
- 6:48Speaker 3: I know you mentioned a few things.
- 6:49Speaker 2: But let me see here.
- 6:52Speaker 3: Type two diabetes potentially in adults, insulin resistance in children
- 6:55Speaker 3: and adults, polycystic ovary syndrome, obesity and high pretension in
- 7:00Speaker 3: children and adults.
- 7:02Speaker 1: Yeah, a lot of terrible stuff. And again this is
- 7:05Speaker 1: not to mention like the pre term births, developmental abnormalities,
- 7:10Speaker 1: like all sorts of different stuff that has to do
- 7:12Speaker 1: with reproduction, breast cancer, tumors, like all of these things.
- 7:17Speaker 1: Like it used to be, like, like you said, we're
- 7:19Speaker 1: not mice. And you know that whole settled science bs that,
- 7:22Speaker 1: like the merchants of doubt used to put out like
- 7:25Speaker 1: just shamelessly, like if you look at meta analyzes of
- 7:30Speaker 1: studies about BPA and its effect on the human body,
- 7:34Speaker 1: like you said, that's what comes up. It's obviously you
- 7:37Speaker 1: can never prove anything like without a shadow of a doubt.
- 7:41Speaker 1: That's just how science works. But it's essentially to the
- 7:44Speaker 1: point where you, the individual person can feel pretty good
- 7:47Speaker 1: about not wanting BPA anywhere near you.
- 7:51Speaker 2: Yeah. For sure.
- 7:52Speaker 3: Europe, of course is leading the way in front of us.
- 7:55Speaker 3: In April, just a few years ago, in twenty twenty three,
- 7:58Speaker 3: they're at DA which is the European Food Safety Authority,
- 8:01Speaker 3: said all right, we've seen the research and I think
- 8:05Speaker 3: they they lowered their safe level a lot. I think
- 8:09Speaker 3: to point two what is that to point two nanograms,
- 8:14Speaker 3: which is two billions of a gram or point two
- 8:18Speaker 3: billions of a gram per day for like, you know,
- 8:23Speaker 3: a human body. So that's that's way lower than ours, is.
- 8:26Speaker 1: Well, yeah, and it's even lower than what their previous
- 8:28Speaker 1: one was. Their previous one was still way lower than ours.
- 8:31Speaker 1: So ours was five milligrams per kilogram. I think it's
- 8:34Speaker 1: the same still, their old one was four micrograms per
- 8:40Speaker 1: kilogram of body weight, so now it's their Their new
- 8:44Speaker 1: revised safe level is twenty thousand times lower than their
- 8:49Speaker 1: own previous safe level, ten billion trillion ish times lower
- 8:54Speaker 1: than are our safe level in the United States. And
- 8:58Speaker 1: when they when the European Food Safety Authority basically decided this,
- 9:05Speaker 1: there were all sorts of like, like, you know, is
- 9:07Speaker 1: this true? Is this right? You know? And of course
- 9:10Speaker 1: industry was pushing back on it. The only paper I
- 9:13Speaker 1: found that was critical of it an academic journal paper
- 9:18Speaker 1: that was critical of their their methods of data collection.
- 9:24Speaker 1: I was like, funded this. It was funded by the
- 9:26Speaker 1: American Chemistry Council. So they're like, it seems pretty like
- 9:30Speaker 1: the EFSA has over the years or since April twenty
- 9:35Speaker 1: twenty three, continued to issue defenses of its decision and
- 9:40Speaker 1: not like we decided, so shut up. They're like, we decided,
- 9:43Speaker 1: and here's why we decided. Here's all the data we
- 9:46Speaker 1: did this on. So it seems pretty legitimate that they're like,
- 9:49Speaker 1: this is way worse than we have been taking it,
- 9:53Speaker 1: and especially in the United States.
- 9:56Speaker 3: Yeah, well if you go to the FDA website today
- 10:00Speaker 3: date April thirtieth, twenty twenty six. It says FDA's current perspective,
- 10:04Speaker 3: based on its most recent safety assessment, is that BPA
- 10:07Speaker 3: is safe at the current levels occurring in foods. Based
- 10:10Speaker 3: on FDA's ongoing safety review of scientific evidence, the available
- 10:13Speaker 3: information continues to support the safety of BPA for the
- 10:16Speaker 3: currently approved uses in food containers and packaging. But if
- 10:21Speaker 3: you don't buy that, and I don't, I don't think
- 10:24Speaker 3: doctor Josh, does you need to look for a label
- 10:27Speaker 3: that says BPA free that will indicate that the plastic
- 10:29Speaker 3: does not have buy cheese.
- 10:34Speaker 2: Bis spinal Is that what you said? He did bis
- 10:37Speaker 2: spent all A.
- 10:38Speaker 3: But like I said, it could have bispon al F
- 10:40Speaker 3: or bispon all S or something else, and that may
- 10:44Speaker 3: be just as risky.
- 10:44Speaker 2: I don't know.
- 10:46Speaker 1: Here's how you remember that. It's like a bisk made
- 10:49Speaker 1: of polyphen hal Yeah.
- 10:52Speaker 2: Oh, I love bisc That's a shame.
- 10:55Speaker 1: Yeah. So if you're like, Okay, BPA free, great, give
- 10:58Speaker 1: it to me. It turns out, like you said, there's
- 11:00Speaker 1: other bisphenols. Bisphenol F and S are now used as substitutes.
- 11:04Speaker 1: They're not nearly as studied as BPA has been. But
- 11:08Speaker 1: essentially the studies that are coming back are like, yeap
- 11:11Speaker 1: just as bad as BPA does all the same things.
- 11:15Speaker 1: So essentially the focus on BPA itself should have been
- 11:19Speaker 1: expanded from the outset to bisphenols, not just BPA. And
- 11:23Speaker 1: so yeah, now there's BPF and bps all over the place.
- 11:28Speaker 1: And if you think that you what you have is
- 11:30Speaker 1: BPA free, is probably still has bisphenols in it.
- 11:34Speaker 2: Why don't they just find something else?
- 11:36Speaker 1: Well, they did, it's called glass. But the problem is
- 11:39Speaker 1: glass stainless steel containers. They often come with plastic tops
- 11:43Speaker 1: and lids, and you have to be careful with that too,
- 11:46Speaker 1: because even if the lids metal, it may still have
- 11:49Speaker 1: a plastic liner on the top of it, and that
- 11:52Speaker 1: probably has at least some sort of plastic associated with
- 11:55Speaker 1: it that could be getting in whatever you're drinking out of.
- 11:58Speaker 2: But do you have to have abys final to have
- 12:01Speaker 2: plastic at all?
- 12:03Speaker 1: I don't know. I guarantee if you really looked into it,
- 12:06Speaker 1: it's like half a cent less, right, something safe?
- 12:09Speaker 2: And that's your answer, you know, Yeah.
- 12:12Speaker 1: One day we're going to get there, Chuck, I hope
- 12:14Speaker 1: we're still alive to see it. But one day we're
- 12:16Speaker 1: going to get there where people actually take care of
- 12:20Speaker 1: other people and we all care about one another, we
- 12:22Speaker 1: all act like it.
- 12:23Speaker 2: We're going to get there, that's right.
- 12:25Speaker 3: And in the meantime, you and I and every other
- 12:28Speaker 3: member of the Stuff you should normally is going to
- 12:29Speaker 3: try and be squeezing through that same door together.
