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, Josef, while I’m not a food chemist by a long-shot, I have studied more than my share of chemistry and engineering. From what I’ve learned along the way, I can’t imagine the extrusion process transforming proteins. Furthermore, if it is capable of such a transformation, if I were still eating flesh, I’d be concerned about all the protein in sausages as well. In fact, given the higher protein content of flesh vs grains, I’d be more concerned about sausage than breakfast cereal.

      It’d help if you could provide the actual reference to your reading… there’s a lot of stuff that gets onto the Internets that has no more support than “people say”… just who are those people, what interest(s) (if any) are underwriting them, and what *exactly* are they saying? I mean, anyone can play that game… I’ve read that eating apple seeds will make apple saplings grow in our stomachs and that swallowing bubble gum will block off our bowels… people say!

      That said, if extruding grains turns grain proteins toxic, I’d think we’d’ve seen major amounts of illness in Italy due to their prodigious pasta consumption… one makes pasta by extruding wheat dough into noodles, protein rich wheat at that. Bottom line: I think it’s safe to eat breakfast cereal but it would be healthier to forgo the heavily processed cereals in favor of whole-food cereals like oats, barley, rice, etc.

    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…..

      • Toxins

        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.

      • RalphRhineau

        To answer your question as to whether Dr Greger is credible? The answer is ‘yes’. He publishes well researched information that is unlikely to be tainted by the agenda of corporate interests.

        The question you’re really posing is whether the good doctor is available or responsive. The answer to that question is ‘no’, or perhaps ‘yes, within the limits of his busy schedule’.

        While I’d love it were I to have a personal relationship with Dr Greger which would allow him to respond to any question I might ask of him, I’m content to benefit from the treasure trove of information that I publishes without seeking or accepting personal compensation.

    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?

  • Moira Galliver

    Could you pls cover the benefits of more herbs and spices. Thankyou
