You've probably been told to not drink diet pop, coffee or juice.
But, no one has probably ever told you to not drink water.
Reporter Sarah Gustin explains why that bottle of water in your cup holder could be deadly.
It's a go to drink of choice.
But that bottle of water sitting in your car could be deadly.
Research shows when plastics bottles heat up, toxic dioxins can be released into the water.
(Dr. Gray / Sanford Health Oncology) "I am sure you have heard people say don't buy bottles for babies that have BPA in it. Those are a type of dioxin and if they melt just a little tiny touch melt, the dioxins are let out into the water and they get concentrated in our body."
Dr. Gray at Sanford Health says not just women are at risk--she says it can cause many types of cancer.
(Dr. Gray / Sanford Health Oncology) "It's not just a woman thing. It can cause cancer in men. Because it is a carcinogen which means it can cause cancer in any body type tissue. It can cause prostate cancer, it can cause breast cancer, it can cause lung cancer. But mostly in places where there is a lot of fat because that is where it is stored."
(Sarah Gustin / email@example.com) "Gray says these days, most bottles of water are safe. But she still recommends checking the label."
(Dr. Gray / Sanford Health Oncology) "Most plastics lately are not made of dioxin types of materials. Some plastics have BPA's in it.
And it's not just water bottles you should be careful with.
(Dr. Gray / Sanford Health Oncology) "Your food when you warm it in the microwave, take the plastic off. Some of those TV dinners, sometimes it's just best to take them our of their plastic when they have that little plastic cover. just take it off."
The good news is, Dr. Gray says it takes more than just one or two bottles to do damage.
(Dr. Gray / Sanford Health Oncology) "It stays in your body for 7-11 years. So it stays in your body for a very long time. So just one bottle here, one bottle there will probably not cause breast cancer or any type of cancer. In fact, everyone is exposed to dioxins. It's in the environment quite a bit. So each one of us has some kind of amount in the body."
Gray also says freezing your water bottle can have the same effect.
She recommends using a glass bottle or not leaving your water bottle in the car.
Musician Sheryl Crow said on the Ellen Show that dioxins in bottled water is what caused her breast cancer.
