I found a canteen kit I really like, however the cup is aluminum and not stainless steel. I vaguely remember reading something here about why aluminum isn't advisble for boiling and cooking, etc, but a search didn't turn anything up. Whats the scoop on this.

I use an aluminum canteen cup. No ill effects yet.
What!

I like Aluminum. Lighweight and inexpensive.

Acidic foods can pick up trace amounts of aluminum from cookware, however, these amounts are very small compared to the amounts you consume on a daily bases. Some autopsy studies find high levels of aluminum in Alzheimer's patients, but many do not. Over half the cookware used now is aluminum alloy, I wouldn't worry too much about your cup.

There shouldn't be any issue at all: none, nada, zip, zilch. Enjoy your cup.

Just be careful drinking hot liquids from an aluminum cup. Hot contents, hot cup, hot lip. It's worse than stainless steel that way.

Aluminum has been found in the brains of some Alzheimers sufferers, but not all, AND it has been found that the Aluminum detected some in autopsied brains may have come from the handling process and not from lifetime accumulation. There is also no proof that aluminum is transferred from eating with aluminum utensils.
OTOH, zinc, which many take as a food supplement, has been attributed to Alzheimer patients.

Aluminum can leach off under hot temps (burner use) esp when cooking acidic foods or foods/drinks containing tannic acid (tea) or cooking fruits (acidic). Daily use CAN accumulate aluminum in the body, particulalry the brain and brain stem.
When I worked at UBC here in BC Canada, one fo the researchers at the Alzheimer's Research Labs did extensive testing of aluminum cookware to find out how much aluminum was leaching off. They found SIGNIFICANT amounts when acidic foods or liquids were cooked, tomato sauce was the worst. Hard anodized pots fared better, but as they wore/aged the concentrations became higher. Worst of all was bare aluminum pots that had seen extensive use and had micro and macro pitting on the surface - the amounts of leached aluminum PER SINGLE USE with acidic foods were equivalent to a full years dose of aluminum (when a normal smooth surface pot was used.)
other studies they did were surveys of the families of Alz. patients, as to the frequency of use of aluminum cookware. It was found that over 70% of Alz sufferers cooked daily with aluminum pots, and cooked acidic foods (beans, soups, sauces, fruits etc).
Aluminum "self protects" itself by forming a constant layer of "corrosion" on the surface. Its microscopic powder that does dissolve nicely in hot water......
food for thought. I prefer stainless personally but have used aluminum cups in the past.
EDIT: I should add that there are MANY other factors that contribute to Alzheimer's....aluminum is only 1 - 2% of the equation

I am told that acidic foods also attack the nickel in stainless steal, which is also not
good for you.
I like to cook with moderate temperatures and use teflon covered aluminum.
Granite-wear is also good. Neither of these impart a taste to the water like
metal containers sometimes do. Both are easy to clean.

What about the Teflon coating that starts to flake and is consumed with your food?? I prefer stainless but normally cook in teflon coated aluminum. I have noticed a definite difference in the taste of the food when cooked in different cookware(stainless,aluminum,cast iron).
