    Please feel free to post any ask-the-doctor type questions here in the comments section and I’d be happy to try to answer them. And check out the other videos on beverages. Also, there are 1,449 other subjects covered in the rest of my videos–please feel free to explore them as well!

      Does food that is brought onto airplanes absorb radiation or harmful properties as result of passing through x-ray scanners and security scanners at airports? How about possible damage to vitamin supplements? Beverages? How about food at the high elevations that airplanes reach, as high altitudes of planes have been known to cause radiation issues in human tissue, no? Would not the same issue possibly apply to food brought on board? Vitamins?

    Lemon wedges have the tendency to have a significant amount of bacteria on them, especially those that you find in restaurants etc.   I always refuse a lemon wedge when offered unless it is prepared at home.

      OTOH, the acid in lemon juice is a natural antibacterial agent.

    Soooo… When they tested white tea and found it was healthier with a lemon wedge, did they account for stomach acid properly?
