    I’m a personal trainer with certifications in fitness nutrition (I’m not a dietitian, those are actual licensed medical practitioners you go to see about dietary needs. I can legally provide guidelines, but I can’t prescribe meal plans.)

    Our body is great at getting rid of toxins and waste products. It’s almost as if we’ve evolved ways of dealing with such things. Anyone talking about “toxins” and “waste products” as if they’re ‘stuck’ in your body is either very ignorant, or trying to sell you snake oil. Probably both. I’ve seen a lot of it, especially in my profession. People making up bullshit to sound knowledgeable and sell you something you don’t need. And yeah, a lot of trainers are just as ignorant and just trying to sell you something you don’t need.

    EDIT: In case anyone wants to sink their teeth into the topic, there’s a very good book I read as part of my course work, called “Nutrition, 6th Edition” by Dr. Paul Insel; Don Ross; Kimberley McMahon; Melissa Bernstein. It’s all very well sourced and kept up to date as modern science catches up. Available on AA if you don’t want to buy it.

        Yeah the dude is really wrong.

        Your body is good at filtering out hydrophilic toxins. But for just about every other toxin… Not so much. Most hydrophobic toxins and other toxins, like heavy metals, VOCs, pesticides, micro plastics, etc., are man made and your body hasn’t had millions of years to evolve natural filters.

        They’ve detected microplastics in breast milk. You know what that means? It’s time to start living up to our name as mammals.

        We hormonally induce lactation for everyone. All the time. Just leech out those microplastics. Nips into 3d printers.

          I walked into my break room at work a couple of years ago and overheard some of my female coworkers complaining about the formula shortage. I asked if they’d ever thought about breastfeeding and they looked at me like I’d just grown a second head. I get that some women here and there might need a supplement for this, but the idea that feeding babies canned formula should be the norm is completely insane.

            Breast feeding is a huge amount of work, asking a person to do that and have a job is a big deal. Pumping breastmilk is incompatible with lots of jobs. If they have already stopped breastfeeding they may not be able to restart.

            It would be great to live in a society where breastfeeding was normal and easy. Society is crazy and women shouldn’t be criticised for trying to exist within it.

          Those are also worth taking into account. Mercury in seafood, for example. Some can be excreted by the human body, others can’t.

          Heavy metal is good for you. Gets you moving and can be cathartic. I prefer stoner, doom, or deathcore myself though. Load my body up with those types of metal.

          Yeah, what do people mean “toxins are pseudoscience”?

          What are microplastics, heavy metals, and PTFAs, then???

            In serious, most ways to loose blood and need blood infusions will loose the plastics too, so the donated blood just maintains the concentrations, the samw way it does for the other components.
            Everyone has plastics in their blood.

            But then if you donate frequently your blood will have lower concentrations due to all the previous donations, so don’t just donate, donate often.

        AFAIK, still no conclusive studies that show microplastics having an overly adverse affect on the human body. I’ve seen one linking it to lower sperm counts, but that’s not particularly bad to me. We don’t need more people.

        The big scare with microplastics is that they are everywhere and that certainly isn’t good; and I think we’re all just waiting for the shoe to drop and some study to come out that shows something majorly negative with them. But for now, there’s nothing obvious sticking out that shows an immediate concern. Which makes sense. We use plastic for so much because it tends not to react to stuff.

          Because they are so ubiquitous that it is impossible to find a control group. Quite literally every single person on the planet has micro plastics in them.

          The problem is that we’ll never know because there’s no control group. Everybody has them, even fetuses still in the womb. You would have to build bunkers with perfect air filtering, and then go through, like, four generations of humans to breed microplastics-free specimen, which you could then use a the control group for the rest… Only them never leaving the bunker would already invalidate the tests… So, yeah…

            If micro plastics were a problem then we should expect to see rapid increases in cancers in younger adults.

              Though even that is complicated by 50 or so years of nuclear weapons testing, which likely also increased cancer rates. Not to mention all that lead everywhere. Produce gradually losing nutrients because farming mostly just focuses on the big three with fertilizer and the others are being mined out of the ground and sent to landfills, septic tanks, waste processing facilities, cemetaries, and crematoriums also doesn’t help (though I’m not sure waste processing and crematoriums remove those nutrients from the cycle like the others, since the one could produce fertilizer and the other might be sending it out into the atmosphere where it could eventually end up back in the soil).

              There’s so much chaos that it’s hard to isolate causes, which then makes all the causes kinda “hide in plain sight” because they can perpetually blame the others and shit only gets worse over time.

          We haven’t noticed much in the way of short term effects, but there’s no way to know what long term effects there will be except to wait.

          In the meantime, since the effects are… unlikely to be beneficial, the best thing to do is reduce exposure as much as possible.

        Good point, those exist. I don’t think we know yet what all of the consequences are, but they’re obviously not good for us.

      There are bio-accumulative toxins that really do get stuck in your body. Lead is a good example. Not that the supposed cures being peddled by these people can actually do anything about those.

      Also, for the normal kind of toxin, the biggest factor keeping the levels in your body high is continued intake. Reducing that totally makes sense. However, you need to first have a real, based on science, understanding of what those toxins are in the first place and not just randomly blame junk food or 5G radiation, and it needs to be a permanent life style change. A two week “cleanse” does nothing. A juice will not detoxify you. (Depending on the juice, especially how filtered and how sugary it is, it may be healthy for other reasons. Standard orange juice is not, it’s way too sugary.)

        There are bioaccumulative toxins, but nothing over the counter sold in a plastic tub by some guy in a tank top will get rid of them. And some, like lead, have symptoms that are not reversible. Lead poisoning is a lifelong condition. So a magical “detoxifying” shoe insole or smoothie additive isn’t going to do much. I think @nightshade@piefed.social 's point remains that any toxins that stay in the body are either gone for good after a short time, or there to stay.

        You make good points. I guess what I really wanted to say is that 90% of the time when people talk about toxins and try to offer up a solution, they don’t even know what they’re trying to talk about. There certainly are substances that bio-accumulate. And as you say, understanding what is actually there, what can be measured, what is problematic, and then reducing intake should be key in solving the issue.

        Another thing I think is important to understand is that the science is continually evolving. I’ve encountered plenty of doctors who insist you should eliminate saturated fat from your diet as much as you can, and that’s key to reducing your odds of heart disease. This is the old hypothetical model of heart disease. Modern studies tend not to agree. But people are still being told the same old things.
