Doctor's Note

 For those scratching their heads over the significance of that red smudge, see my explanation of the comet tail test in Cancer, Interrupted: Garlic & Flavonoids.

For those that missed my last two videos on the safety of common spices, see Update on Cinnamon for Blood Sugar Control,  and Don't Eat Too Much Nutmeg.

This new tarragon finding reminds me a bit about the in vitro data raising questions about the safety of avocados (Are Avocados Bad for You?) that thankfully appeared to not translate out into population studies. I'll keep an eye out for new data and post to the NutritionFacts.org Facebook page if I find anything. In the meanwhile, there are a bunch of other reasons to avoid canned fish:

    Hi Dr. Greger,

    I don’t remember the comet test you reference. Which video could I watch to refresh my memory about it?

    Hello Dr. Greger,

    I have an unrelated question about extruded breakfast cereal (your site says to post any questions under video comments). I’ve been reading that the processes of extrusion renders the proteins in grains toxic. I’m hoping you can address this either in a video or your FAQ.

    Thanks!

    Hi Dr. Greger,

    Just wondering… how do we know that chervil doesn’t have any mutagenic properties?

    Curious Dr. Greger…does this rule apply to all varieties of tarragon? Or as I am hoping, it’s specific to the A. Dracunculus species… I grow Tagetes Lucida which is in the same family but has a different genus and family. I also talk about it in presentations so needless to say I’m very curious about this. Thank you.

      Sorry Dr. Greger, but are you really credible? You don’t seem to answer any questions…..

        I, among others, are part of the nutritionfacts team. We are here to answer questions to the best of our knowledge. Although at first, it was possible for Dr. Greger to acknowledge everyone’s question, the volume of questions is so great there is no way he can get to them all now as the popularity of this website has grown. He does respond to some every so often.

    Hello Dr. I am a culinary student and i have to do a presentation about tarragon and i came across your video i was wondering if you were talking about a specific kind of tarragon of just tarragon in general?
