Be far more concerned about your food and drinks coming in plastic packaging than some char on your food (which makes it taste good). Think about since the explosion of plastic being used over glass and waxed cardboard and the rise in cancer rates. Just some food for thought.
Plastic has been used for food storage and serving for over half a century.
I just looked at the National Cancer Institute's web page, and death from cancer in the USA since 1990 has fallen 25%. So deaths are down, but what about number of new cases per year?
If you go to CDC Cancer Data site:
https://gis.cdc.gov/Cancer/USCS/DataViz.html
and then use their data visualization tool, you will find a
very slight increase in the total number of new cancer cases each year over the past quarter century. However, if you then look at the
rate of new cancer cases over the same period, they have gone down. That is because the increase in total cases is driven by our significant population increase over that period, not by an actual increase in the percentage of people getting cancer.
So, to summarize: there is no "explosion" in plastic use, and in fact soda has come in plastic bottles since the late 1970s. And, cancer rates are down, not up, and cancer mortality is
way down.
Don't get me wrong, I'm no fan of plastic and try to use glass and other things for food storage. I also wish the beverage industry would go back to re-usable glass bottles. Many people in this forum are old enough to remember how beverages were sold up until the mid-1960s: when you finished your soda, you put it back into the carton and took the six-pack back to the store. They sent it back to the bottler who washed the bottles and re-used them. These bottles ended up looking rather beaten up, with the logos faded, and etching on the glass from the cleaning.
Unfortunately, the same people who complain about environmental impacts of one-use items would be the first to object to the potential health hazards of reusing bottles, so this old approach will probably never come back into use.
Finally, there is always some study that tells me there is something wrong with pretty much anything: aluminum cookware causes Alzheimer's disease; stainless steel leaches poisonous chromium and cobalt into the food; non-stick coatings cause cancer; iron from CI pans is toxic; etc., etc.
Something is going to kill you, but I'll bet it won't be plastic.
