> there’s a clear connection between the consumption of a diet high in linoleic acid and CVD mortality. That's interesting. The Wikipedia page for linoleic acid (https://en.m.wikipedia.org/wiki/Linoleic_acid https://en.m.wikipedia.org/wiki/Linoleic_acid) says this under Health Effects: > Consumption of linoleic acid has been associated with lowering the risk of cardiovascular disease and premature death Linking this study: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7326588/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7326588/ It's so hard to get any conclusive answers at all in food/health science...

Not only is it hard to get any conclusive answers at all in food/health science... I find it's very hard to even identify controversies, scientific mysteries and open questions. The posture adopted tends to always give the impression of consensus and knowledge.

  The posture of what, scientific media reporting? Nearly all papers that I've read generally state confidence, needed work, and confounding factors

Linoleic acid is an essential nutrient, but the recommended daily intakes are between 11 g and 17 g, depending on sex and age. Most vegetable oils, the main exceptions being olive oil and high-oleic sunflower oil (not classic sunflower oil), have a very high content of linoleic oil, so the daily intake can be obtained from less than 2 spoons of oil. Those who use for cooking vegetable oils high in linoleic acid, or who eat mostly industrially-processed food, typically eat significantly more linoleic acid than the recommended intake. When linoleic acid is in excess over what the body needs, it can be stored only in limited quantities in reserve fat, which must contain other fatty acids in higher proportions. Therefore the excess part of the linoleic acid, over what can be consumed or stored, must be transformed into those other fatty acids, in the liver. This extra work for the liver is undesirable, and when the processing capability of the liver is also exceeded, then some of the fat in the body can have an abnormal composition, too high in linoleic acid. The best is to eat mostly vegetable oils that are high in oleic acid, because those also include enough linoleic acid to cover all needs, and if they are eaten in excess, their fatty acids are just used to synthesize human reserve fat, which has a similar composition.
