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..
But what you may not know is that there's no such thing as a canola plant. What we call canola oil is, in fact, low-erucic acid rapeseed oil that was crossbred by a scientist in Saskatoon named Richard Keith Downey. The name canola is derived from Canadian Oil, Low Acidity. During WWII, inedible rapeseed oil was used as a high-temperature lubricant on steam ships, but with the switch to diesel engines in the following decade, industrial demand declined.
