Did we get dietary saturated fats all wrong? The #HADLmodel provides a new understanding and an opportunity to get it right. THREAD👇👇👇

Increased dietary saturated fatty acids lead to increased cholesterol in lipoproteins, but we don’t know why. Enter the #HADLmodel, which explains changes in lipoprotein cholesterol as adaptive homeostatic adjustments that ensure optimal cell membrane fluidity and cell function.
We propose that circulating lipoproteins enable appropriate redistribution of cholesterol molecules between specific cells and tissues, to accomodate changes in dietary fatty acid supply, due to our omnivore nature and variable intake of fatty acids. #HADLmodel
Our #HADLmodel implies that circulating levels of LDL change for protective, not for pathological reasons; an SFA-induced raise in LDL cholesterol in healthy individuals is a normal response, while a lack of this needed response may reflect a deeper pathology in lipid handling.
Circulating lipoproteins may change for pathological reasons, when regulatory mechanisms become disrupted by pathogenic processes related e.g. to inflammatory processes. Diverging lipoprotein responses in healthy versus metabolically unhealthy individuals support this view.
Low grade inflammation can interfere with several fine-tuned signaling pathways necessary for homeostasis, including proper lipid handling. Altered circulating cholesterol levels may here reflect underlying pathogenic processes, unrelated to saturated fat intake. #HADLmodel
Dietary factors causing chronic low-grade inflammation, driven by diet-microbiome interactions, should receive more attention. The role of saturated fats in pathogenesis may be misconceived and greatly exaggerated. #HADLmodel
Is the #HADLmodel impossible? Is there more evidence to support the model? What else do we need to test in high-quality studies? Keep the discussion going - fair and factual. We need to improve the conversation on dietary fats. #publichealth #dietaryguidelines

So it turns out that an organization I thought was doing good work, the False Memory Syndrome Foundation (associated with Center for Inquiry, James Randi, and Martin Gardner) was actually caping for pedophiles. Uhhhh oops?


Since this, bizarrely, turned out to be one of my longest videos ever (??) here's a quick thread to sum it up for those of you like myself with short attention spans. 1/10

In the '90s the False Memory Syndrome Foundation was founded to call attention to the problem of adults suddenly "remembering" child abuse that never actually happened, often under hypnosis. Skeptics like James Randi & Martin Gardner joined their board. 2/10

A new article reveals that the FMSF was founded by parents who had been credibly and PRIVATELY accused of molestation by their now-adult daughter. They publicized the accusation, destroyed the daughter's reputation, and started the foundation. 3/10

The FMSF assumed any accused pedo who joined was innocent, saying "We are a good-looking bunch of people, graying hair, well dressed, healthy, smiling; just about every person who has attended is someone you would surely find interesting and want to count as a friend" 😬 4/10

The chorus of this song uses the shlokas taken from Sundarkand of Ramayana.

It is a series of Sanskrit shlokas recited by Jambavant to Hanuman to remind Him of his true potential.

1. धीवर प्रसार शौर्य भरा: The brave persevering one, your bravery is taking you forward.


2. उतसारा स्थिरा घम्भीरा: The one who is leaping higher and higher, who is firm and stable and seriously determined.

3. ुग्रामा असामा शौर्या भावा: He is strong, and without an equal in the ability/mentality to fight

4. रौद्रमा नवा भीतिर्मा: His anger will cause new fears in his foes.

5.विजिटरीपुरु धीरधारा, कलोथरा शिखरा कठोरा: This is a complex expression seen only in Indic language poetry. The poet is stating that Shivudu is experiencing the intensity of climbing a tough peak, and likening

it to the feeling in a hard battle, when you see your enemy defeated, and blood flowing like a rivulet. This is classical Veera rasa.

6.कुलकु थारथिलीथा गम्भीरा, जाया विराट वीरा: His rough body itself is like a sharp weapon (because he is determined to win). Hail this complete

hero of the world.

7.विलयगागनथाला भिकारा, गरज्जद्धरा गारा: The hero is destructive in the air/sky as well (because he can leap at an enemy from a great height). He can defeat the enemy (simply) with his fearsome roar of war.
