Polyunsaturated Fats

[Jing]

Modification of high saturated fat diet with n-3 polyunsaturated fat improves glucose intolerance and vascular dysfunction is this saying polyunsaturated fats are better than saturates? Or am I reading it wrong?

The rats had been fed 60% of their totally energy as lard, with much of the rest being soybean oil. I would guess that they had a DHA deficiency, which inhibits glucose flux in the brain. You only need a little α-linoleic acid for this, amounts so low they're nearly impossible to avoid unless you're a laboratory rat being fed a diet engineered to exclude it. Lard does have stearic acid and this can be a membrane lipid; although this is the fatty acid most consistently found protective in cancer, the shorter chains of coconut oil would be more pro-metabolic. If you're looking for a population of people who actually ate 60% of their calories as coconut, look no further than the Tokelau islanders who's diets had been fully detailed by Ian Prior:
