    Lead effects taste?

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    I had one of those crazy thoughts on the drive home.

    On the show "Hestons Feast" the chef Heston Blumenthal said that the Romans tastes were dulled by the amount of lead that was consumed in their diets. Namely in Rome where lead pipes were used. This led to recipes that were very very strong on the palate. Like lambs brain custard with fermented fish guts.

    In the last few decades there has been the push by the government to reduce the amount of lead in the human environment. No lead in paint, unleaded petrol etc. This was to reduce health problems mainly in children.

    So my crazy thought is: maybe as a by product of this the Australian palate has become more sensitive? Could it be driving the food and coffee scene? It seems that as the levels of lead have gone down the levels of good food and coffee has gone up.

    Is this plausible or just another crazy thought?

    It seems like a logical idea, that and the fact technology has improved so better equipment and brewing, even cooking utensils. e.g. heaps of pans with pfte on them, compared to cast iron frying pans.
    With the better technology they maybe able to extract more inert flavours from foods that havent been tasted as something in the processed covered it up.

    The teflon is probably taking up where the lead has left off (coating tongues etc) :P, interesting idea though.

    IMO just a crazy thought.

    Lead was removed from paint a long time ago.
    From petrol more recently yes.
    We havent eaten off plates containing lead or even used lead pipes in this country as far as I know.

    Maybe its the trend towards healthier eating thats doing it..

    When I had some surgery 5 years ago I came out unable to eat much for almost a week.
    The resultant forced detox increased the sensitivity of my palate a thousand fold.

    I could almost count the number of parsley flakes in my chicken noodle soup, if could have counted fast enough I swear I could have counted the bubbles in a mouthful of soft drink.

    Everything tasted sublime!!!

    Eventually after eating my usual diet for a while everything went back to "normal".

    LEAD IS IN THE GROUP HEAD OF YOUR MACHINE !!!!
    (well most likely.... and maybe many other parts of the machine?)

    so stop drinking coffee...... I had a laugh

    Lead content

    To enhance the machinability of brass, lead is often added in concentrations of around 2%. This lead is present on the surface of the material, and thus presents a health concern similar to that of pure lead. Silicon is an alternative material, however when silicon is used in a brass alloy, the scrap must never be mixed with leaded brass scrap because of contamination and safety problems.

    Background:

    Brass is a metal alloy primarily composed of copper, tin and varying amounts of lead. Antique brass may contain very high levels of lead, while brass manufactured in the United States after 1986 usually contains no more than 7-8% lead. In both instances, the lead may leach from the brass.

    Brass containing faucets and submersible pumps:

    Brass is found in faucets and submersible well pumps. As the water sits in brass faucets, lead may leach into the water in excess of the EPA action level of 15ppb (parts per billion). This is especially true for the 12 million water wells that are equipped with brass bearing submersible pumps. Recent studies have demonstrated that the lead level in well water standing in contact with brass for eight hours increased as much as 20 fold. Under these conditions the lead levels sometimes exceeded 50ppb! Although EPA regulations of 1986 limit lead in brass faucets to 8%, this regulation does not apply to submersible well pumps.


    oh and whatever you DO NOT swim in Fremantle habour after drinking at little creatures........ thats chock full of lead....

    I know that was tongue in cheek:) but take this with a grain of salt :)

    Until the last decade there were no routine machines that could detect 15ppb, this is an extremely low level. You were breathing in many hundreds/thousands times this quantity when cars ran on leaded petrol. Most routine labs will not detect up 50ppb ::) The yanks are absurd - They tried to bring in laws banning all lead containing products last year, including motorvehicle parts (only the yanks could think that someone was gonna chow down on a throttle cable :D) thankfully sanity prevailed.
    Back *on topic - The leaching process is very slow , Ill rephrase that extremely slow, a quick flush of your grouphead will remove any nasties that may have formed. :)

    Just some other lead facts:
    For Adults - 90% of lead entering the body via the mouth does not enter the blood stream.
    * - 95% of lead entering via airways enters the blood (has nowhere else to go).
    * - Adults need relativiley large doses of lead to observe either shortterm or long term effects - dont let this think it cant harm you :-? - and generally recover without any longterm effects.
    Children (preadolescent)- have remarkable metabolisms and nearly all injested or airway lead enters the blood. They are affected at even low intakes. Lead has a detrimental effect both on mental and physical development in children.
    I was part of a team monitoring lead in blood in the workforce, community and environment surrounding a lead smelter.
    ps lead tastes quite sweet, Im told, which is why kids used to like eating the old lead paint. :o

    No has mentioned the positive side.

    If you are allergic to kryptonite lead comes in handy.
