Effects of Coffee, Cream and Sugar
Although coffee is brewed with water, drinking coffee makes the kidneys excrete more water than normal. This dehydrating action can change your body fluid's natural balance of electrolytes, acidic compounds and alkaline compounds. The U.S. Food and Drug Administration notes that the caffeine in coffee increases gastric acid secretion, while the lactose in cream and sucrose in sugar increase your blood glucose level. Like these factors, even decaffeinated coffee, nonfat milk and artificial sweeteners can affect your blood chemistry and skew the results of your blood analysis.
