I wasn't able to figure this out so I called a friend.  They told me that "shabloot" translated to chestnut but they questioned the spelling.  It's a transliteration though so...

  "shabloot" seemed to point to "chestnut" in English but those are no chestnuts I've ever seen.  Google image search has been rendered absolutely useless so that didn't help one bit.  Anyway... I thought maybe it was date seeds and found this on the NIH website:

"Accordingly, in our study, it is hypothesised that supplementation with date seed powder (DSP), as an efficient adjuvant treatment, can improve hyperglycaemia, insulin resistance, hyperlipidaemia, oxidative stress, anti-/inflammatory status, mental health and dysbiosis of the gut microbiota in patients with T2DM "

 and this from iopscience:

"Conclusion: the active substances in date palm seeds can improve oxidative stress in pancreatic beta cells so that it can restore insulin production. Consumption of date seeds has the potential to reduce blood glucose levels in hyperglycemic patients and does not change the glycemic index in normal people."

 After comparing more images, I realized it can't be date seeds either but hey, maybe philipma1957 can use date seed power until we figure out what the heck those things are.  I decided to give it one last try and I'm fairly confident that we're looking at acorns from the mighty oak.



  It would have been nice if there were a few stray caps in the image you provided to help verify but... I'm 95% sure that's what they are.  I don't know anyone who eats them around here - I mean you can eat them but they require processing to remove the tannins otherwise, you'll probably feel sick... you could poison yourself but before that, your tongue will feel like the insole of your boot.  That being said, once properly processed, they are very nutritious and maybe they're also helpful when it comes to treating diabetes:

"Acorn muffins could be utilized as an adjuvant therapy to control appetite and ameliorate glycated haemoglobin in patients with type 2 diabetes. However, further investigations are required for a more comprehensive conclusion." - https://pmc.ncbi.nlm.nih.gov/articles/PMC9922149/

 Have you eaten them?  If so, how do you prepare them?
