Yeah.
And I would say that quality of fat does matter.
And we can talk some more about that, but I think fat plays a role with artery elasticity, which is another...
component of vascular risk.
And, you know, it's interesting, Mark, because that scenario is also associated with that cholesterol profile we talked about with the small, dense LDL and low HDL and the sequelae that we usually link to diabetes, fatty liver, peripheral neuropathy, all these other organs that are affected.
And it can happen with the high insulins alone before the sugars go up.
It's a metabolic imbalance.
Right. Well, there's a lot of the chemical sunscreens like Avobenzone. I don't even know all of the names of them, the chemical sunscreens. And many of those are potential endocrine-destructing chemicals as well. The flip side is, Mark, I'm one of those people who grew up in the South, had more than my share of sunburns, had my first skin cancer when I was 37.
So I also want to slow down skin aging and wrinkles and skin cancer. So we kind of have to say, well, how do you get the protection you want? without putting yourself at risk. I personally am a real fan of the zinc and titanium, the mineral-based sunscreens, or even just a hat covering your skin, staying out of the sun in the middle of the day.
I mean, I think there's a lot of other things we can do that are going to be safer for us and safer for the planet. One of my favorite one-stop shopping places to learn more about safety levels and which either skincare or sunscreens contain things we do or don't want is the Environmental Working Group. And I know you've been a big supporter of their work for years.
I think they were some of the pioneers really raising awareness. And what I love about them is they have a safe cosmetics database that you can search by type. So you could search sunscreens. Or you could search by brand, plug in your favorite brand and see how it rates to others on their list.
Yeah, so that's another one. I mean, you know, work in the Berkshires, ticks are everywhere. So for those of us who love to be in the woods, you always have to be mindful of enjoying your time in the beautiful woods and hiking. without putting yourself at risk for getting a tick-borne illness. So how do we navigate that balance as well?
For people who are super concerned, I don't know how you feel about this, but if you tuck your pants into your socks and put a little deed around where they join, maybe that's enough. I don't know. I don't do it. I mean, I hike all the time.
And the other nice thing about being in the Berkshires, I can come home, strip on my front porch, stick my gloves on the outside, go in and do my tic-tac, because I think that's probably the most important thing. The other interesting piece, though, is there's emerging science-based evidence that some essential oils may be almost effective at repelling ticks.
There's been some research on lemon eucalyptus oil, on thyme oil, on citronella. So I think that is another reasonable option to try to get some of the tick repellent benefits without causing harm.
Well, I'm glad you pointed out that we absorb things through the skin. So we think we put it on our skin and it's just going to stay on the outside, but it can potentially get inside our bodies. And one of the challenges, Mark, is trying to do good research to actually prove cause and effect when you're looking at some of the carriers or products
preservatives that are added to the things like the the cosmetics that we put on our skin um you know our old model of what happens with toxicity is the dose makes the poison you know you have to have massive amounts for it to have a negative impact but there's so many things that are in our skin care products like phthalates or parabens that have been dubbed endocrine disrupting chemicals
And what that means is even tiny amounts, especially at critical windows may actually muck up hormonal signaling and have long lasting impacts. That's less related to the dose, but the cumulative exposure over time. Um, yeah. So it's hard to tease out.
I mean, you might be having exposures every day in teeny tiny amounts that don't seem immediately problematic, but down the road when you're struggling with insulin resistance or breast cancer or uterine fibroids or thyroid issues, it could be related to these endocrine disrupting chemicals that have wreaked havoc on our hormone balance.
It's a great question. So, parabens typically are added as a preservative to extend the shelf life of your skin creams or your topical creams. Rancid. Yeah. So you can keep it on yourself for a year or two and it won't smell funny or it won't go bad. And so you don't get bacteria. I mean, some of them are trying to keep contaminants out.
