Plant Lectins Linked To Parkinson's

Good post.

[park_bear]

This study draws conclusions based on the effect of plant lectins on the neurons of the 1 millimeter long flatworm Caenorhabditis elegans. It claims the lectins were transmitted interneuron. No attempt was made to exclude other modes of transmission. No attempt was made to check other cells of the creature to see if lectins were generally present throughout.

As set forth in the paper, there is a huge variety of lectins and they are present in a huge variety of foods.

I regard this study as speculative and not actionable.

This was the best Gundry could come up with his plant paradox book as evidence lectins cause Parkinson's.

Surely, it is highly probable that Parkinson's starts in the gut and Gundry does go overboard, I think, claiming lectins are the cause of nearly every disease. That said, he does make a compelling case lectins do cause gut permeability and based on his book, and other related research, we are making a serious effort to eliminate them from our diet. How about you? Do you find enough data out there to make an effort to eliminate it from your diet?

Gundry's book has been thoroughly refuted, here: nutritionstudies.org/the-pl... Nothing he says can be trusted.

As for lectins, that is an extremely broad category: "Lectins are carbohydrate-binding proteins, macromolecules that are highly specific for sugar moieties. Lectins perform recognition on the cellular and molecular level and play numerous roles in biological recognition phenomena involving cells, carbohydrates, and proteins"

en.wikipedia.org/wiki/Lectin

For me to start being concerned about this I would need to see convincing evidence regarding one or more particular lectins.

Well, this article certainly does demolish Dr. Grundy's credibility. (I made a reference to Grundy in a previous post which I now have to go back and delete.) For many of us, certainly for myself, trying to decipher the abstracts that are posted on this forum are well above our pay grade. Unlike Dr. John Gray, of Mars/Venus fame, Dr. Grundy actually has legitimate credentials which means, essentially, as we read these articles and abstracts, credentials alone mean nothing. It seems like for every authoritative, competent, well credentialed nutritionist that says one thing, there is another equally well credentialed nutritionist that says the opposite. What's a body to do?

Once again, thank you park_bear. That lectin avoidance diet was really hard to pull off, anyway. I'm glad to be done with it.

I would invite you to post this link as a new topic as I've read a lot of posts indicating a lot of people are subscribing to Grundy's message.

Indeed, surely Gundry must know better. This entire affair seems like one big practical joke. We cannot expect a public confessional however, given that Gundry is profiting from the book and his line of supplements. Or maybe this was all done on a bet and he will give all the profits to charity and then fess up. One can always dream.

Perhaps the title to this existing discussion will be sufficient to draw interested parties.

'nothing he says can be trusted'. Wow, that's a bit of over each. Have you read his book? Have you followed his diet. I have and it's helping restore my gut health. Gluten is a lectin...and plenty of people have g.I. problems with it in their diet and have chosen to eliminate it.

[MBAnderson in reply to Blackfeather]

The link does undermine Grundy's credibility because the authors are precise in pointing out references of Grundy's that are invalid. Actually, the referencing is awful. Lectins are apparently more complex than to be cast in black-and-white terms as either being good or bad. I don't doubt that some lectins cause gut permeability and should be avoided, but I don't know which ones.

[park_bear in reply to Blackfeather]

Yes I sure did read his book, and I checked his claimed but invalid reference to Parkinson's long before you posted it here. Now I need to ask you to please carefully read the very thorough refutation nutritionstudies.org/the-pl... This reference demonstrates that indeed nothing Gundry says is to be trusted.

As to as to gluten intolerance, yes that is a very real thing and many people suffer from it. Gluten has many components, one of which, WGA, is a lectin. Lectins are an extremely broad category and just because one of them causes trouble does not convict all of them as being bad actors.

Eat right and live right for your type by Peter d'adamo is another book that specifically refers to your blood type and the lectins that your blood type is sensitive to.

There's quite a bit that you can do to disable some of the lectins. Its hinges on how you are preparing the food and cooking it.

I guess if you sprout the grains you would disable the lectins in the grain. Also if you are a bean lover you want to cook your beans on high temperatures and not in a crock pot.

Here is the link about lectins which I have just begun to read, but, so far, it seems to be making the case in some lectins are good and some are bad. This link is probably been posted before, but it seems relevant to this discussion.
