In one study, nine trial subjects each ate one egg & ham sandwich of 900 calories from a fast food restaurant.
By means of a series of blood samples taken before and after eating the sandwich, a dramatic increase was observed in the amount of free radicals and substances promoting inflammation in the blood; at the same time, the amount of anti-inflammatory substances was reduced. The study also showed that the content of sugar and fat in the blood inhibits the ability of the vessels to dilate and contract concurrently with the changing need for more or less blood to vital organs. This could also lead to blood pressure problems.
The series of experiments also showed that trial subjects who were given 1,200 I.U. of vitamin E and 500 mg. of vitamin C before a glucose load had fewer inflammatory substances in their blood and also avoided the increase in free radicals compared to the ones who were not given antioxidants.
