Plastics

According to The Green Guide, a website and magazine devoted to greener living and owned by the National Geographic Society, the safest plastics for repeated use in storing food are made from high-density polyethylene (HDPE, or plastic #2), low-density polyethylene (LDPE, or plastic #4) and polypropylene (PP, or plastic #5). [Ref]
Some of its food storage containers use polycarbonate (plastic #7), which has been shown to leach the harmful hormone-disrupting chemical Bisphenol A (BPA) into food items after repeated uses. Beyond BPA, other chemicals can be found in various food storage containers. Containers made out of polyethylene terephthalate (PET or PETE, or plastic #1)—such as most soda bottles—are OK to use once, but can leach carcinogenic, hormone-disrupting phthalates when used over and over again. … Also, many deli items come wrapped in plastic made from polyvinyl chloride (PVC, or plastic #3), which can leach cancer-causing dioxins. Containers made of polystyrene (PS, or plastic #6, also known as Styrofoam) can also be dangerous, as its base component, styrene, has been associated with skin, eye and respiratory irritation, depression, fatigue, compromised kidney function, and central nervous system damage.

Refridgeration

Water-soluble nutrients like vitamins C and B and a group of nutrients called polyphenolics are often lost in processing. For instance, studies show that after six months, frozen cherries have lost as much as 50 percent of anthocyanins, the healthful compounds found in the pigment of red and blue fruits and vegetables.
