>This doesn’t have much use for physical applications. It’s kind of particle physicists doing particle physicist things.

Would you say it's similar to the math community calculating more digits of pi?

“The intracellular VC concentration is strictly regulated in order to maintain levels of 80–100 μM in the plasma [2, 3]. However, intravenous injection bypasses this strict regulation, allowing specific VC concentrations to be maintained within a specified period, thereby providing a pharmacological basis for its therapeutic application [4]. Several pioneering studies have demonstrated the efficacy of pharmacological VC in improving the survival of patients with advanced cancers [5, 6]. In contrast, two randomized double-blind controlled trials failed to demonstrate any benefit of VC against advanced malignant disease [7, 8]. Therefore, the route of administration is important for high-dose VC to have a therapeutic effect, and only intravenous administration results in sufficiently high plasma and urine concentrations to allow potential antitumor activity [9].”

The authors are using the term pharmacological to refer to plasma concentrations that are only achievable by IV administration.

Per the authors, the body regulates Vitamin C to 80-100uM so you can't just consume more of it. IV administration however gets around the natural intestinal absorption limits.

So unless you plan to shoot up your supplements, this doesn't seem applicable to typical person just yet. Though I must say I'm imagining a funny skit where we see what appears to be a drug den of people shooting up and it's a bunch of natural herbalist types cooking up and injecting vitamin c from a pile of oranges.

While I agree with the sentiment, it is mostly not poor people who are doing this. Sure, often they are used as pawns to start the clearing, but some big miners and landowners, as well as companies, are the ones profiting.

The headline is confusing first we say fat is protective then we say it causes dementia and stroke so either it is beneficial or dangerous this headline is a true mystery indeed.

While Brazil bears responsibility, let's not forget that what is mined or produced there is for global supply chains. So fostering due diligence in supply chains, regulations, etc should be done by the recipient countries as well.

Mindfulness is not behavioral modification— it’s about learning to recognize and sit with the reality of the present and what your senses reveal about that state. Behavioral modification is about training yourself into good habits through small actions which eventually lead to bigger ones. Eventually mindfulness can lead to behavioral change once the individual becomes aware of actions that do not serve them well, but the onus for change comes from a completely different place
