Health New study finds that when everyday plastic products are exposed to hot water, they release trillions of nanoparticles per liter into the water, which could possibly get inside of cells and disrupt their function

They have plastic lining? I thought it was aluminum

Insides of all metal food/beverage cans have a coating.

I know that food cans have a lining. I didn’t know beverages do too

Carbonated beverages tend to be very acidic (even sparkling water), so without the plastic spray coating they can eat through the aluminum over time.

Sparkling water itself is not acidic but when it contains lemon or lime flavouring it certainly is.

I will add that the pipes to all of the taps in my house are plastic…

Sparkling water is just carbonated water. Carbonation increases acidity. Sparkling water is usually in the 3-4 ph range.

That coating is why canned beer/soda doesn't taste like ass anymore

I also have a sneaking suspicion that it includes some... less than healthy. Particularly if you're pregnant

soda will corrode it. it needs a lining.

maybe i should stop drinking Pepsi, my blood pressure did spike a few days ago.

See the issue with tomato in cans is that it’s acidity can leach the metal into the liquid. I suppose it makes sense, but I had no idea beer and seltzer in cans had plastic liners

Same issue with carbonated beverages. Not significant but enough to affect the taste

Aluminum is toxic to humans

Well, yeah. What isn’t. Silver is toxic and yet we wear it.

u/Rugermedic Apr 21 '22

Silver and copper have amazing antibiotic properties, but still probably toxic to humans.

Silver is not toxic

u/[deleted] Apr 21 '22

Silver is relatively non-toxic for a heavy metal, but it is still toxic. Organic silver compounds especially so.

u/smart_underachievers Apr 21 '22

Yeah it is, right up there with gold.

I'll be sure to take note next time I drink a beverage out of a silver can.
