Are Plastic Containers Unhealthy?

Dr. Weil's Q&A at

advised that "polycarbonate plastic containers may not be safe for storage and transport of food and beverages. Better choices are polypropylene (#5 pp), high-density polyethylene (#2 hdpe), and low-density polyethylene (#4 LDPE)." The answer particularly highlights the risk of insulin resistance i.e. risk of type-2 diabetes associated with using the unsafe plastic bottles. It prompted me to check a government site for more info. And here it is:

Indeed, only the bottles labeled with #2, #4, or #5 recycling number seem to be relatively safe, if you have to use plastic instead of glass or ceramic containers.
