The bloodâbrain barrier is formed by brain endothelial cells, which are connected by tight junctions with an extremely high electrical resistivity of at least 0.1 Ïâm.he BBB is distinct from the quite similar bloodâcerebrospinal-fluid barrier, which is a function of the choroidal cells of the choroid plexus, and from the bloodâretinal barrier, which can be considered a part of the whole realm of such barriers. Several areas of the human brain are not on the brain side of the BBB.
Canola oil (provided that it has not been hydrogenated to increase its stability) contains very small amounts of trans fatty acids at levels too low to be a health concern. The levels of trans fat in non-hydrogenated canola oil are below 0.5 grams per serving and qualify for a label claim of trans fat free..
Marketers claim that any bad data on coconut oil are due to hydrogenation, and virgin coconut oil is not hydrogenated. But only a small percentage, 8%, of coconut oil is unsaturated fat, which means only 8% of coconut oil gets hydrogenated. And the yield is mostly stearic acid, the one common long-chain saturated fatty acid that has minimal impact on LDL cholesterol levels.
