Remember back when most everything that couldn't be sold as is or in boxes, came in glass containers? I remember a little town down river from my paternal grandparents' home that had a glass bottle manufacturing factory. We drove right by it on our way to Grandma's house. Now it seems that glass containers are getting to be a rarity and plastic has taken over. Glass was the perfect sanitary container that didn't leach hardly anything bad into the contents. That is after they lowered the lead levels in the glass. A lot of older drinking glasses and goblets contained a lot of lead, although, if you just used them for drinking and didn't store anything in them, they should not cause any health problems.
In today's world, most food and liquid containers are made of plastic and newer fresh water plumbing is plastic. We drink water from plastic bottles and food comes in plastic lined cans. The average person eats or drinks from some form of plastic container every day. Therefore there is a worry that people consume way too much BPA which is found in the plastic that bottles and food containers are made from and in the linings of cans. BPA is known to be a cause of breast and prostate cancers, among other health problems.
There was a scientific study done to see if BPA was as bad as thought and if it did get into your body just from drinking and eating from plastic containers. Twenty people who switched from canned and plastic-stored foods to fresh items for three days had their BPA levels drop sixty-six percent. When they went back to their regular diets, their BPA levels shot back up. This shows that the majority of BPA exposure is from food packaging. So, what about other types of plastic? Who knows what health risks are involved with them. My opinion is that plastics are a product of the modern world and the human body is not equipped to handle the consumption of them, even very small amounts. Drink from glass containers and have a great day, you hear?
