What a pleasant surprise to hear from the ROB patriarch so soon. As always, a solid & amusing read! Great reminders to seek the old paths of butter in health accumulation. 👌
That statistic of screen time & babies is absolutely heartbreaking though. Wow.
My take on longevity has to do with this observation: The degree of fatty acid unsaturation of mitochondrial membrane lipids has been found to be one of those biochemical parameters that are most strongly correlated with longevity, when different species of mammals and birds are compared, with a low degree of fatty unsaturation being correlated with less lipid peroxidation and a longer normal life-span. https://pmc.ncbi.nlm.nih.gov/articles/PMC2875212/
Another animal science researcher noted that "During fasting/refeeding cycles and increased levels of exercise, tissue PUFA concentrations have been shown to deplete rapidly in both humans and rats. These studies show that most PUFAs, including α-linolenic acid (ALA) and linoleic acid (LA), are preferentially oxidized in periods of exercise or fasting. During refeeding, SFAs and monounsaturated fatty acids (MUFAs), such as palmitic acid and oleic acid, are also more rapidly replaced than any of the PUFAs. Similarly, the concentrations of most plasma PUFAs and MUFAs have been shown to be significantly lower in rats fed a high fat ketogenic diet than in controls. The predicted increase in FA oxidation in free-ranging cheetahs is therefore likely to also skew their serum FA profiles toward lower proportional serum concentrations of PUFAs and MUFAs relative to SFA." https://pmc.ncbi.nlm.nih.gov/articles/PMC5167222/
Finally, a 'pentadecanoic acid benefits' web search yields an AI Overview that says, "Pentadecanoic acid (C15:0) is an odd-chain saturated fatty acid with emerging evidence supporting its role as an essential nutrient for cellular health, longevity, and metabolic function. Studies suggest it boosts cellular membrane integrity, reduces inflammation, improves mitochondrial function, and lowers the risk of type 2 diabetes, heart disease, and nonalcoholic fatty liver disease."
AI Query: What food consumed by humans has the highest concentrations of C15: 0?
Response: The food with the highest concentration of C15:0 (pentadecanoic acid) is whole-fat butter.

Thank you for sharing that verse
