About 250 milligrams of caffeine â or the equivalent of 2 to 2 1/2 cups (473 to 591 milliliters) of plain, brewed coffee â a day may cause this effect. If you have type 2 diabetes and you're struggling to control your blood sugar levels, limiting the amount of caffeine in your diet may provide a benefit.
Candida then feeds on this sugar and grows more out of control.â. This seems to make sense, and upon further research it seems that it is true that caffeine causes your blood sugar levels to spike. I stopped the coffee, but relied on stuff like taking small pieces of caffeine pills to give me energy.
