Harmful Plastics


Recently, there has been increasing controversy over the use of plastics as food and beverage storage containers.
There are both health and environmental risks which must be taken in consideration.
Plastic is non-biodegradable and remains in landfills, where it leaches harmful chemicals into the soil and water.
Plastics are made using petroleum (crude oil), a non-sustainable, polluting and limited resource.

Plastics are numbered 1-7.
The type of plastic (number) is listed on the bottom of the container.

Each plastic is composed of different chemicals and each carries unique health concerns.
Fetuses are especially sensitive, and health problems may take place in utero, long before birth.

PETE #1 (Polyethylene Terephthalate)

water bottles, soda bottles, cooking oil bottles, and peanut butter jars
not designed to be reused
break down easily, leaching chemicals into your body

Reusing these containers causes microscopic scratches and cracks, which serve as reservoirs for bacteria
phthalates increase the risk of reproductive cancers and infertility

HDPE #2 (High Density Polyethylene)
Detergent bottles and milk bottles generally considered safer for storing food and water

PVC #3 (Polyvinyl Chloride)
Made of vinyl and used in medical equipment, plastic furniture, shrink wrap, and liquid detergent containers
no food or drink should ever be stored in these containers
dioxins contribute to lung cancer, endocrine and autoimmune conditions
phthalates cause liver, kidney, and testicular damage

LDPE #4 (Low Density Polyethylene)
Plastic bags and food storage containers generally considered a safer plastic

PP #5 (Polypropylene)
Bottle caps, drinking straws, syrup and yogurt containers, Rubbermaid®
considered a safer type of plastic

PS #6 (Polystyrene)
Styrofoam especially toxic when heated (i.e. when used for coffee or take-out) causes reproductive problems and cancer

Other #7 (Polycarbonate)
Plastic baby bottles, sippy cups, water cooler containers, microwave dishes, inside lining of cans, utensils, and Nalgene bottles
bisphenol-A disrupts hormones, and mimics estrogen
minute amounts of this substance can result in: reproductive disorders such infertility, endometriosis, fibroids, low sperm count; prostate, breast, uterine, ovarian cancer; hypo- or hyper- thyroidism; early puberty; hyperactivity; obesity
new bio-based plastics labeled #7 are apparently “safer” to use
What can you do to protect yourself?

Although it is impossible to eliminate exposure to plastics, here are some tips to help limit exposure:

Never use plastics #3, 6, 7
Only use #1 plastic bottles one time (better to avoid altogether)

Store food in ceramic or glass containers (especially fatty foods)
Use glass or stainless steel for filtered tap water

Never microwave anything plastic (even if it is “microwave safe”)

Never use Styrofoam for hot drinks or food
