Aluminum is in everyone's diet and more so in those who cook with aluminum pots and eat certain prepared foods.
The first sentence of the abstract is: "It is well known that Al absorption is markedly enhanced by citrate."

As H. Gilbert Welch might say, to state that the Al absorption is markedly enhanced doesn't have much meaning unless you know where you are starting from. My question is whether consuming citrate from dietary sources or supplements will be a problem and this leaves it still unclear.
In "Aluminum Exposure and Metabolism" 1997, Vol. 34, No. 5 , Pages 439-474 http://informahealthcare.com/doi/abs/10.3109/10408369709006422
, they state, "Typically gastrointestinal absorption of aluminum from diets is <1%." Still, not clear how much this 1% is! From this it would appear to me the risk of Al absorption is normally low if a person is not cooking with aluminum and not taking Al in supplements. Then the danger citrate would pose on Al toxicity would likely be low. Since I don't have access to the full journal articles, my investigation is hampered by only reading the abstracts...maybe one of the articles actually gives the absolute levels of absorption, but I didn't find it.
On another topic, the presentations by H. Gilbert Welch last weekend were both great! Haven't watched all the weekend videos yet, but looking forward to the always great folks you bring in for these weekends!
