Safe, Healthy Tupperware?

Like waterbottles and water, tupperware holds the food we put into our bodies. And, similarly, tupperware materials can leach into our food1 and from there into our body2, if we aren't careful. The risk with tupperware may actually be greater because we heat up our leftovers in tupperware3. If we are using plastic food containers, this can cause increased leaching into our food.

Cara's Market recommends several alternatives for housing your food. 

My personal favorite is glass tupperware.

Less-ideal attributes include:

  • Heavier than most other options
  • Some reports of exploding tupperware when going between extreme heat

Benefits include:

  • No risk of leaching and no linings, phthalate free
  • Easy to clean and dishwasher-safe
  • Microwavable

Despite the cons, this is the option I prefer for my home - it gives me the most peace of mind. Below are some options if you are interested in glass tupperware. Otherwise, there are other additional tupperware solutions below.

Stainless Steel Tupperware

Less-ideal attributes:

  • Can't be microwaved or easily re-heated


  • Lighter than glass, good for lunchboxes and the road
  • No BPA/BPS, no lining, phthalate free


    Not all tupperware is created equal for your health

    Silicone Tupperware

    Less-ideal attributes:

    • Doesn't maintain shape under higher temperatures

    Benefits include:

    • A lightweight option
    • BPA/BPS and phthalate free
    • Should not leach chemicals into food
