Question from Shauna
Good morning, I stumbled upon your website trying to research stainless steel products from China. I recently got my kids a set of stainless steel cups to drink water from. We primarily drink water or carbonated water in our house. Occasionally they do drink milk. Will nickel be leached into the water? I read your stainless steel section and I couldn’t come to a conclusion as to whether or not they are safe for drinking. It looks like it is only a concern if you have a nickel allergy? Is that right? I am trying to remove toxic Substances from my home and I am starting with the ones that are food and bodies come in contact with. I appreciate your work on your website and I can’t wait to dig in a little deeper.

I just posted an article on drinking beverages from stainless steel. Read it here. It is best to use stainless steel marked #304 or 18/8. Do the cups have a marking on them? The study finds that low-acid beverages do not leach. Unfortunately, this is just one study so more information would be beneficial. I would not recommend using stainless steel for carbonated water as it is more acidic (PH of 3-4) which is more likely to causes leaching. I use stainless steel bottles for plain water when glass is not practical.
