CRITIQUES, RULES, AND NOTES

Be aware of the following rules before posting comments:
- Please do not post summaries of the video in the comments - it damages retention on the video and YouTube is less likely to promote it (these videos cost me a lot of money to produce).

Critiques of my work are welcome! Please be aware of the following notes & rules before submitting critique:

Be mindful that this content is not all encompassing on the subject at hand and is self-limited for brevity to reach a wider audience. Also, be aware that I receive hundreds of YouTube comments per day, so the only way your critique can be considered is if you follow the steps outlined below. Finally, YouTube auto-deletes links, so I do not see most comments with links attached.

RULES:
If your comment is rude, you will be banned.
If your comment is not about the studies/topics at hand (i.e. extending to other outcomes not discussed) or offers critique with no scientific basis, it is unlikely to receive a response.

If you can follow these rules, I will try to address your critique and if there is merit, I will add an AMENDMENT to the content in question and pin it so everyone can see it (thank you!).

Mindsip insights from this episode:

Reconsider regular vitamin D3 supplements for kidney health

Studies using regular, over-the-counter vitamin D3 supplements tend to find mild to no benefit for improving kidney health.

Raise blood vitamin D level to 30 ng/mL to reduce kidney inflammation

You should aim to raise your blood vitamin D level to at least 30 nanograms per milliliter to help reduce the risk of kidney inflammation.

Avoid NSAID abuse to protect kidney health

Abusing certain over-the-counter pain relief medications like NSAIDs (e.g., ibuprofen) is toxic to your kidneys.

Preserve kidney function by controlling blood sugar and blood pressure

Your best bet for preserving kidney function is to control blood sugar, maintain normal blood pressure, and avoid over-consuming kidney-toxic substances.

Reduce blood sugar to protect kidney cells

High blood sugar causes immune cells to release a molecule called TNF alpha, which kills critical kidney filtering cells known as podocytes.

Utilize prescribed activated vitamin D for chronic kidney disease benefits

Only a prescribed, 'activated' form of vitamin D shows potential benefits, and this is primarily for people already diagnosed with chronic kidney disease.

Address vitamin D deficiency to reduce inflammation

Immune cells from people with low vitamin D secrete more of the harmful TNF alpha molecule when exposed to high glucose.
