Interesting video on fibre by @mariokratz.bsky.social
In his typical dispassionate and objective style, Mario Kratz discusses different aspects of fibre, a nutrient that has always fascinated me, mainly because of the promise that it is satiating.

Excellent and matter-of-fact presentation by @mariokratz.bsky.social on insulin resistance and how to diagnose, prevent and treat it. Highly recommended!
Insulin resistance is one of the key factors underlying type 2 diabetes and prediabetes. And even among people with normal glucose tolerance, many are insulin resistant.

To learn how you can determine whether - and why - you are insulin resistant, and what you can do about it:

If you are interested in insulin, obesity, and diabetes, I highly recommend this conversation with @jimjohnsonsci.bsky.social

Jim is very knowledgeable, but what I really appreciated here was his thoughtful and open-minded consideration of the cumulative evidence on each issue.

Bravo!

A common claim online is that only small, dense LDL particles are atherogenic, and that large, buoyant, or "fluffy", LDL particles can safely be ignored.

What is all of that about?

What does the scientific evidence say?

Valuable contribution by Anahad O'Connor about food additives in UPFs.

The key here is that most additives are not tested or regulated by any agency. Instead, the food companies use a loophole to declare them safe and use them as desired.

How potentially harmful additives have infiltrated America’s food
A legal loophole allows companies to add new additives into your food without approval from the Food and Drug Administration. The consequences can be dire.
