Yes, you could imagine that if you're drinking out of a plastic bottle, that that's gonna have microplastics.
But like you said, Megan, I was really surprised when I realized this, and that's why I've talked about it so much, that the paper coffee cups we get from any coffee store are lined with plastic.
And anytime you're putting boiling water into plastic, it is just exploding plastic.
And let's just talk numbers, right?
So there was a study done at Columbia University, and they're using a special type of microscopy, which is really the gold standard for assaying microplastics and nanoplastics.
And the distinction is made based on the size of the plastic particle.
If you're less than one micrometer, if you're in the nanometer range, you're talking about nanoplastics.
And I think this is the major issue that most people are not talking about.
So Columbia looks at bottled water, 250,000 nanoplastics per liter, 250,000.
Now, the same could probably be said of these coffee cups when you pour boiling water into them.
I'm thinking half a million to a million micro nanoplastics per liter.
There was also a study done at Columbia looking at a can of Coca-Cola.
I don't think people realize this.
Cans are lined with plastic invariably.
Soup cans, soda cans, energy drink cans, beer cans.
A can of Coca-Cola had 3.7 million nanoplastics.
And this possibly is because it's an acidic drink because it has the sulfuric acid and these acids and the benzoic acid and the Coca-Cola.
But an acidic drink in a plastic container is probably even more microplastic.
So I think we need more research because you look at what people are drinking out of and it's all cans now or plastic bottles or soup cans.
Soup cans are filled hot.
