Hello Sue,
Below is a page that almost answers your question about how much oil was used in the Brachial Artery Tournequest Test. The answer was 50 grams. However, that is a weight measurement which comes to equal just under 1.8 ounces by weight. The tricky part though is that we meausure oils by fluid ounces and not by weight ounces.
I did a Google search and discovered that a gallon of Olive Oil weighs 7.6 lbs.
There are 16 weight ounces to a pound so a gallon of Olive Oil is equal to 121.6 weight ounces.
There are 128 fluid ounces in a gallon. So a fluid ounce of olive oil would weight .95 of an ounce.
(To figure out the weight of one fluid ounce of olive oil we would divide 121.6 weight ounces by 128 to get the weight of a fluid ounce of olive oil. That would be 121.6/128= .95 of an ounce)
So, if my math is correct to figure the liquid equivalent we would multiple the weight ounces by .95 to get the fluid ounces. That would mean that 1.8 weight ounces would be a volume of 1.71 fluid ounces. So, the answer is that 1.71 fluid ounces was the amount they were using in the Brachial Artery Tournequest Test.
Now the question is how much is 1.71 fluid ounces?
There are 8 ounces to a cup. There are 16 tablespoons to a cup.
So, one ounce equals 2 Tablespoons (16/8=2)
1.71 ounces equals 3.42 Tablespoons (1.71x2=3.42)
So, that does seem like a significant amount of oil for the test. But, it also does not invalidate the test. If you eat less oil you will possibly have less damage.
Also, I am going to ask some other people to double check my math and see if maybe they also have an easier way to know the answer to this question.
Here is the web site where I read that the meausrement they used was 50 grams. Hopefully this is correct:
