New game: Good, bad, or useless? Helpful, harmful, or just, a waste of money.
First up: zinc-containing nasal gel as a cold remedy. It’s unclear whether oral zinc supplements help with a cold, but what about squirting zinc up your nose? Good, bad, or just snakeoil?
Bad. More than 100 reports of people losing their sense of smell, some permanently—forever.

To see any graphs, charts, graphics, images, and quotes to which Dr. Greger may be referring watch the above video. This is just an approximation of the audio contributed by veganmontreal.

      Dr Greger, Why does fresh beet juice make me so instantly and very, very ill?
      Thanks,
      Sandra

        There could be several reasons. You could be allergic to the beets or just have a food intolerance. Dr. McDougall has a good post on “Allergic Reactions to Foods” on his website, http://www.drmcdougall.com/med_allergic.html. His recommended approach is very practical as it often difficult to pinpoint the reason for your reaction. Clearly you should avoid the food. If the reaction consists of trouble breathing I would suggest being evaluated by an allergist. Best wishes.

    Are there any reports about those using oral Zinc-Gluconate cold treatments, such as those offered by Zicam, Cold-Eeze, and their generic equivalents?  These are often in the form of lozenges, or oral sprays.  Can these cause permanent loss of the ability to perceive scent?
