I often read, and remember hear in a Danny Roddy/Haidut Podcast that Palmitic and stearic acid were the best fatty acids for mitochondria respiration. But everything I find in pubmed says the contrary.
"Saturated palmitic and stearic acids decreased insulin-induced glycogen synthesis, glucose oxidation, and lactate production. Basal glucose oxidation was also reduced. Palmitic and stearic acids impaired mitochondrial function as demonstrated by decrease of both mitochondrial hyperpolarization and ATP generation"*
" As opposed to saturated FFA, unsaturated FFA did not impair glucose metabolism and mitochondrial function"
