Here are observations made on a cohort comprising me and myself, followed my my poorly substantiated ramblings - you choose how much credibility you give them.
- After eating much unsaturated fat, like the sauce for an artichoke, I get within 1-2 hours a layer of fluid oil on my skin, especially at the had and ears;
- After eating much bad fat, like cheese or sausage, I get acne within hours, again at the had and ears.
So could the process be as simple as:
- The fats our skin exudes reflect, in amount and composition, what we recently ingested;
- When these fats are thick, they clog the pores and build acne?
Nice: after eating a pizza with cheese and salami, if I swallow two teaspoons of sunflower oil, I don't get acne.
Opinions, observations, experience?
Even dissent maybe?----------
More ramblings.
Thick fats like cheese or bacon seem poorly soluble in thin fats like olive oil, so if ingested in separated meals, the thick fats will deposit in the arteries and clog them, while thin fats won't dissolve them afterwards.
But
if ingested at the same meal, they will swap their fatty acids in the stomach (do they?) to build a set of new fats, rather fluid, that don't clog the arteries.
At least, this is consistent with the so-called "Mediterranean diet". Having lived in Madrid, I testify that Spaniards ingest big amounts of chorizo, queso and jamón, not outweighed by olive oil. But the difference is that they eat significant light fats at most meals, be it over bread or as cooking oil.
The discussion is lighted...
