  1. Complacency and Regulation of Aluminium in Food

    Chris Exley, Keele University

    15 September 2010

    In spite of the clear results and recommendations of our study the Food Standards Agency (FSA) in the UK has not made any official comment regarding our findings. The Food Safety Act of 2007 (updated in 2008) specifically states under article 5 that infant formulas should not contain anything which might 'endanger the health of infants and young children'. The Chief Scientist at the FSA, Andrew Wadge, responding to my enquiry on his blog has said that the aluminium content of most infant formulas are within the tolerable weekly limit (TWI) of 1 mg/kg body weight, set by the Joint FAO/WHO Expert Committee on Food Additives,20-29 June 2006, Rome. He concedes that there are no regulatory requirements for aluminium in food. He does not mention that the TWI set by the aforementioned committee is for adults and that this committee concede that the value they have given is simply a best guess. It is not based upon any human studies,adults or children, only laboratory studies on rats and mice. The committee admits that even these sources of information are incomplete.

    We carried out and published our investigation of the aluminium content of infant formulas because of our concern for the welfare of infants. We did our best to produce a balanced and non-sensationalised account of the problem and we made some suggestions as to what might happen next. It is clear from the defensive nature of the very few responses from the industry that they do not accept that there is a problem and it would seem that they have the support of the regulatory authority in the UK (FSA) and Europe (EFSA).

    We are a world-leading authority on human exposure to aluminium and the consequences for human health and we believe that something has to be done about the aluminium content of infant formulas and, indeed, the aluminium content of food in general. Why is the aluminium content of food not regulated? Why are regulatory authorities such as the FSA using TWIs for aluminium which have little scientific value and absolutely no value with respect to human consumption?
    It is clear to us that both the manufacturers of infant formulas and the regulatory authorities are hoping that by remaining silent on this issue that it will very quickly become a non-issue. Are we content to continue to feed our preterm and term infants with high levels of aluminium? Will we have to wait another 20 years for another study to show that the aluminium content of infant formulas are still too high?

    None but my curiosity for aluminium and its role in biological systems.

  2. Chris is right

    I think the concern of Chris and his collegues is reasonable, the problem raised by them is common over the world. I hope it can be taken into consideration, emphosized and resolved by authorities and producers.

  3. ignoring 100ys of independent research

    The regulatory authorities have been successful in their strategy of ignoring independent research, ever since 1911.

    “These studies have convinced me that the use in food of aluminium or any other aluminium compound is a dangerous practice. That the aluminium ion is very toxic is well known. That aluminized food yields soluble aluminium compounds to gastric juice (and stomach contents) has been demonstrated. That such soluble aluminium is in part absorbed and carried to all parts of the body by the blood can no longer be doubted. That the organism can "tolerate" such treatment without suffering harmful consequences has not been shown. It is believed that the facts in this paper will give emphasis to my conviction that aluminium should be excluded from food” WJ Gies JAMA 1911;LVII(10):816-821.

    It appears that there is no end in cherry picking data either, to support “convenient” viewpoints on controversial issues.

    “Most researchers no longer regard aluminum as a risk factor for Alzheimer's disease... At this point, there is no convincing evidence that aluminum increases a person's risk of developing Alzheimer's disease” Alzheimer’s Society

    …whilst the Alzhemier’s Associations regards aluminium’s role in AD as “a myth”

    I am assuming that the following literature must have somehow escaped their attention:

    If the public opinion is swayed towards the idea that aluminium in general is non-toxic, then it is gives a false justification to those (referred to as the alleged “majority of researchers”) who have a vested interest in keeping relevant information away from the eyes of the public.
