Phthalates tend to be embedded with fragrances to make things smell pleasing to us. So we put them on our bodies and those are also endocrine disrupting chemicals.
That's a great question, Mark. In studies that are trying to tease out how they influence our health, they often look at urinary levels to see how much people are exposed to. It's a little bit challenging, however, because it turns out that all of us show evidence of exposure to these chemicals.
So it's a little bit hard to know what to do with measurements other than trying to do it from a scientific standpoint, say, do the levels track with health outcomes? In clinical practice, I have not done that. I don't know if you found it helpful or not. And when I was first looking at it, we ended up coming back to the same recommendations anyway.
We need to reduce exposure and find ways to support your body's getting rid of them.
Yeah, I think that's really important to understand that there are critical windows or critical timeframes, but it's even more important to reduce exposure. And one of those classic timeframes is when a woman is pregnant. Even little bits of exposures in utero may affect the fetus, and then those impacts persist into adolescence.
A study a few years ago, what they did, a lot of the data has to be correlative, but they measured urinary levels of phthalates and parabens in women. two different points in their pregnancy. And then when their babies were born, they tracked them for nine, 10, 11 years.
And they found that higher levels of phthalates and parabens in the urine, the daughters of women with those higher levels ended up going into puberty earlier, which now that doesn't prove cause and effect, but you know, sometimes you can't ethically design a study. And when we see research like that, that it does correlate with endocrine challenges down the road, We have to take that seriously.
We have to take that seriously. There's been some other research linking exposure in utero in particular or early childhood to phthalates and parabens to higher incidence of ADHD-like symptoms in adolescents, so even neurodevelopment.
Again, a lot of the data is correlative and epidemiologic, but we can't really design a placebo-controlled double-blinded trial to willingly expose one group of women and not expose another and track their children for 20 years.
You know, Mark, before we jump into that, I want to come back to something that you just said about the fat biopsy. And I know that urine levels can sometimes be really helpful at motivating people to say, oh my gosh, I need to look at this.
But we have to be aware that even if they're not showing up in the urine, if we've had old exposures, they do tend to get positive in fact, and we're not doing fat biopsies on people. I just want to point that out. So don't use an okay looking urine to say, okay, not a problem for me.
And it's been a concern as well if those are all residing as deposits in fat tissue. If somebody really rapidly loses weight and starts to mobilize all those stored toxins, it could potentially put extra burden on a lot of different processes in the body. So it's just food for thought. And you had... And you have done a lot of podcasts on detoxification, and it really is coming back to the basics.
I mean, how do we get rid of things? We break a sweat by going out in the woods or exercising or sitting in a sauna. We really have to focus on optimal gut function, fiber dense diet, a healthy microbiome and specific foods that support all of our detoxification pathways. We can talk about a few of those. drinking enough water.
I mean, it's really, I don't know that there is a super magic for these endocrine disrupting chemicals, except it's really important to make sure our detoxifying enzymes have the new chance they need to do their job.
Yeah, we need B vitamins. We need magnesium. We need the sulfur containing amino acids that are rich in foods like broccoli, kale, Brussels sprouts, garlic, onions, the allium family. Um, antioxidant rich foods can kind of fill the gap.
Some of the deeply pigmented fruits and vegetables, you know, similar thing, I think that's come up in other areas, but those are some of the foods that are most important. Prebiotic rich foods that can select out a healthy, robust, diverse microbiome that can also kind of, if we have detoxified and mobilized things can help us get rid of it and clear it out of our system.
Do you have any favorites yourself?
Stress itself is not bad for us. It can be good for us. And so just dividing things up in our mind to think about, is this an event? Is this an episode that I can recover from? Or is this a situation in my life that I'm going to live with forever and I have to get used to?
So these chronic stressors like having a child with a chronic condition, having a conflictual relationship, job stress, these are the types of addiction, loved ones with addiction, health problems. I mean, years and years and years go on where we need to be coping with it in a different way because it's not about getting rid of the situation.
The acute stressors are really pointing us to just thinking about the stress response in the moment in dealing with an episode within a day. What does that stress response look like? And as you were saying, when we think about
