Which Plastics Are Safe?

The news about plastics has been pretty alarming lately, causing some of us to go dashing for the water bottles to see what kind of plastic they are—and find out if we’ve been unwittingly poisoning our children and ourselves with chemicals leaching into the water from them.

If you’ve been concerned, here is a handy chart that identifies the good, bad, and OK plastics and where they are found. Find out here:

which-plastics-are-safe

1 Polyethylene terephthalate (PET or PETE)
Used to make soft drink, water, sports drink, ketchup, and salad dressing bottles, and peanut butter, pickle, jelly and jam jars.
GOOD: Not known to leach any chemicals that are suspected of causing cancer or disrupting hormones.

2 High density polyethylene (HDPE)
Milk, water, and juice bottles, yogurt and margarine tubs, cereal box liners, and grocery, trash, and retail bags.
GOOD: Not known to leach any chemicals that are suspected of causing cancer or disrupting hormones.

3 Polyvinyl chloride (V or PVC)
Most cling-wrapped meats, cheeses, and other foods sold in delicatessens and groceries are wrapped in PVC.
BAD: To soften into its flexible form, manufacturers add “plasticizers” during production. Traces of these chemicals can leach out of PVC when in contact with foods. According to the National Institutes of Health, di-2-ethylhexyl phthalate (DEHP), commonly found in PVC, is a suspected human carcinogen.

4 Low-density polyethylene (LDPE)
Some bread and frozen food bags and squeezable bottles.
OK: Not known to leach any chemicals that are suspected of causing cancer or disrupting hormones, but not as widely recycled as #1 or #2.

5 Polypropylene (PP)
Some ketchup bottles and yogurt and margarine tubs.
OK: Hazardous during production, but not known to leach any chemicals that are suspected of causing cancer or disrupting hormones. Not as widely recycled as #1 and #2.

6 Polystyrene (PS)
Foam insulation and also for hard applications (e.g. cups, some toys)
BAD: Benzene (material used in production) is a known human carcinogen. Butadiene and styrene (the basic building block of the plastic) are suspected carcinogens. Energy intensive and poor recycling.

7 Other (usually polycarbonate)
Baby bottles, microwave ovenware, eating utensils, plastic coating for metal cans
BAD: Made with biphenyl-A, a chemical invented in the 1930s in search for synthetic estrogens. A hormone disruptor. Simulates the action of estrogen when tested in human breast cancer studies. Can leach into food as product ages.

..... look at the US National Library of Medicine National Institutes of Health here

- at temperatures above 22 degrees C it leaches antimony. If you don't amend this erroneous article it will imply you think antimony is good for you!

Sounds like you've been through quite a journey Susan but failed to miss something so ridiculously obvious!

As much as plastics stink for health especially when microwaved due to the fact that a pinch of many of the chemicals used to produce polymers would be lethal if ingested & they're so easily released with heat & EMF's... Microwaving food in itself is ridiculously TOXIC!

Microwaves convert essential amino acid's into known cancer causing agents as well as annihilating the health promoting antioxidants in food that fight free radical damage in the first place.

Also, sorry to say this but when it comes to cancer treatment such as chemo & the meds you're on now doctors know exactly what they're doing & it's not in your best interest, it's in the interest of their bank accounts, predominantly their superiors accounts, & your perpetuated ill health & dependency on their medications & treatments is exactly what they want!

If you truly want to be healthy & free of illness look into the ketogenic diet. All the best with your journey & I wish you great joy!

Here's an old study that sheds a little light on microwaves & a very informative article about keto principles which are known to cure most every illness on Earth be it terminal, untreatable, or treatable with crappy pharmaceuticals:
