A report on a BATT experiment
An experiment with the Branchial Artery Tourniquet Test conducted by Robert Vogel from the University of Maryland.
A group of young subjects were taken to a fast-food restaurant. Half ate cornflakes and their BART was normal.
The other half had hash browns and sausage and "... within 120 minutes they couldn't dilate the blood vessel. They had so tortured, so absolutely assaulted their endothelial cells they could not manufacture enough nitric oxide to dilate the artery." (Dr. Esselstyn, eCornell lecture).
