Difference of initial (average) and final blood pressures in Mean Arterial Pressure (MAP):
MAP = 2/3 (DP) + 1/3 (SP) *Systolic Pressure (SP) and Diastolic Pressure (DP)
Subject 1, who ate the Kit Kat bar, shows a steady increase in mean arterial pressure after eating the Kit Kat bar. However, it cannot be concluded that eating a Kit Kat bar increases the blood pressure of a subject because subject 2 has inconclusive results with no steady pattern. Subjects 3 and 4 both had their highest mean arterial pressure after 20 minutes of eating a banana, and both had a large decline in MAP after 30 minutes of consuming the banana. Nonetheless, this does not show that a banana has an effect on blood pressure either. It seems that the banana and the Kit Kat do not affect the blood pressure of a person. The results would be more decisive if more test subjects were used to measure the effects of these foods on blood pressure.
