    hey, do you have an idea about the toxicity of this coffee machine https://media.machines4u.com.au/mac...ee-Machine-Grinder-Hire-Rental_14133498.l.jpg
    ?
    or any one that look like it like this one

    .
    i can only make coffee in the house during weekend and during the other days of the week i don't drink it because i,m studying for long hours in the university and don't have the time to get back home, so i wondered about the toxicity of the espresso machines in the cafeteria?

    i don't know if it's plastic or stainless steel or other type but i think it's plastic because stainless steel would be expensive if every cafeteria buys it.

    if it's plastic then it's a problem, the water stays in the machine for hours and there is a filter there that makes it hot when making the coffee.

    i don't know if drinking it will outweigh the downs or not, i mean better than not drinking it at all during these days of the week.

    what do you think?

    I am not an expert on espresso machines, but I believe the heat chamber or element, I am not sure of which or both maybe, is made out of brass on most of the machines made. Brass is usually made up of copper and zinc, other alloys can include aluminum, even lead and arsenic (doubting/hoping that is not the case with espresso machines). So, that could contribute to consuming more of these inorganic metals, and potentiate mineral imbalancing or toxicity, if you drank enough of them.

    thanks, any ideas about electric coffee machines like this one? https://www.freecomm.it/aziende/390100/prodotti/S_PLEFFFBW.jpg

    Yeah, cheaper machines have some plastic tubes inside, but expensive machines should have a almost fully metal pathway for the water. It shouldn't be a problem because the coffee grounds would filter out any leeching metals.
    Caffeine: A vitamin-like nutrient, or adaptogen. Questions about tea and coffee, cancer and other degenerative diseases, and the hormones.
    "Coffee drinkers have been found to have lower cadmium in tissues; coffee making removes heavy metals from water."

    The other machine depends on if the heated water comes into contact with plastic, it could have BPA/BPS/Xenoestrogens. If you have good metabolism occasionally that shouldn't be a problem. You get those basically all the time from everything if you live in a city. I think some more expensive ones probably have more metal parts.

    Just my take, but I am not sure coffee grounds filters heavy metals, they are in a dissolved form and only making one pass through, at high pressure no less .Since ultra hot water 'extracts' components from the coffee grounds, I doubt any filtering is happening, the whole espresso process is all about extraction, and the metals will come right along with the flavors, dissolved solids, and color pigments. I would still keep espresso drinking to a reasonable limit.

    "Micke Mc Laughlin, (2000) of CSIRO, Australia has found that coffee has capacity to bind with heavy metals. Heavy metal content of water was much reduced after addition of caffeine. Dissolved heavy metal ions are positively charged and coffee contains uncharged and negatively charged molecules, the metals ions might be taken out of solution by binding to negatively charged molecules in the coffee granules."

    Nice finding, i forgot this sentence from that article in dr peat's website.
    So even if there is a chance of getting BPA when hot water get in contact with the plastic, still caffeine will increase the metabolism and so with a higher metabolism the chance of detoxing heavy metals from the body will be much higher than having slow metabolism.
    in the second picture, that's the type of my machine, any ideas about the safety of heating/boiling water using electricity?
