Awhile back, we switched to glass containers to hold leftovers for my husband's lunch. He didn't mind the extra weight of the containers... until he started riding a bicycle to work with a pack on his back. Now he prefers the light-weight plastic containers again (who wouldn't?).
I worried a bit about BPA, but then I came across this quote about recycling codes:
"Four, five, one and two...
All the rest are bad for you."
I went through our plastic food storage containers and breathed a sigh of relief. They have a code of five.
Glass is preferable, but I don't worry (quite as much) about the plastic containers killing him off any time soon; now, if I could just rest easy while he pedals to work! (I ask him to text me every day to let me know he arrived safely: not "smished.")
