Putting extremely acid foods items-- including tomatoes or even citrus fruit products-- in these products does the very same factor, Vandenberg mentioned.
The "microwave safe" tag on some plastic containers doesn't mean the item is entirely risk-free from a health and wellness standpoint, she incorporated.
" Several of the plasticizers as well as chemicals can transfer from the plastic containers into the food during heating," Rogers pointed out. "So our experts entirely support that you move your food items from a plastic container right into a glass bowl as well as microwave it by doing this.".
