I know that aluminum doesn't belong in the human body. As a canister to hold liquids which will be consumed later, is aluminum good or bad to use?
In my opinion.... Typical plastic bottles with bpa are the worst for you. Aluminum bottles are a step up and great for the environment since aluminum does not require pollutive materials to make and the material itself is not hazardous to the environment like plastic is. Hard plastic bottles without bpa and other harmful materials/chemicals is better for your health as long as it is not exposed to the sun or heat. Stainless steal containers are great to use, but what can be even better?. Water containers that are made out of animals. Example: animal skin, goat bladder. Animal bladders do a great job holding in animal urine, why not use them to hold drinkable water?? You also do not have to worry about any harmful product getting inside your body since animals are 100% biodegradable and they are natural to the environment. When I deploy to Iraq, im going to find a goat and rip out its bladder! Then im going to convert it into a water container for my camelbak!
aluminum cans have a plastic coating on the inside to prevent poisoning aluminum is bad for you
Not really. Al in your diet is believed to be a cause of Alzheimer's disease. And putting acids (like fruit juice) in a bottle would definitely corrode the metal somewhat; water is slower but there is a taste that means that some Al is going in. Thus many (most/all?) Al bottles are lined in plastic and have plastic closures. Stainless steel with a stainless steel closure are a much better choice than Al. But they are harder to find and often more expensive. Stainless steel with polyprop. closures but not plastic lined are easier to find (but less durable; I am forever breaking off the poly tabs). Of course Al bottles are better than plastic bottles.
