Okay, Let's talk plastic. What are all those acronyms and numbers on the bottom of all plastic containers? They refer to the type of plastic used. Which ones are safe and which ones should you avoid? When looking at plastic, just remember this jingle - 5, 4, 1, and 2; all the rest aren't good for you. Any other numbers try to avoid - this includes plastic picnic utinsels! So if you see those numbers on the bottom of plastic containers, you're relatively okay. HOWEVER, PETE (1) (or PET) plastic, is the worst of the best because it leaches a high amount of estrogen-like chemicals (this includes BPA-free plastics!). PP (5) is the safest, then HDPE (2), LDPE (4), and finally PET / PETE (1).
