Caffeine And Fluid Balance
However, Maughan and Griffin went on to say that the dangers of caffeine-caused diuresis have been overrated. They reviewed many scientific articles published on caffeine and fluid balance that were published between 1966 and 2002. The review showed that although large doses of caffeine taken in a short period of time can stimulate urine output, people quickly develop tolerance to the effects of the caffeine, diminishing the diuretic effect in those who regularly consume coffee or tea. Maughan and Griffin concluded the caffeine doses found in standard servings of caffeinated beverages such as tea, coffee or energy drinks would not affect fluid balance.
The Amount Of Coffee You Drink Matters
Whether coffee is good or bad for your health depends on many factors, including the type of coffee, the amount you drink and how sensitive you are to caffeine.
In general, moderate coffee consumption one or two 8-ounce cups per day doesnt seem to be harmful. Some studies even suggest that coffee may have health benefits, such as a reduced risk of Parkinsons disease and death from certain conditions, such as heart disease and stroke.
Blood Pressure Additives
But keep in mind that too much caffeine can cause side effects, such as insomnia, anxiety, irritability, nausea and an increased heart rate. If you experience any of these effects, cut back on your intake.
Caffeine sensitivities vary from person to person, so its important to pay attention to how much coffee youre drinking and how it affects your body. If you have kidney disease, speak with your doctor about the amount of caffeine that is safe for you. In general, people with chronic kidney disease should limit their intake of caffeine to less than 300 mg per day.
So if you love coffee but are worried about its effects on your kidneys, its best to consult your doctor and make sure that coffee is a safe option for you. With proper management and moderation, however, you can enjoy this popular beverage without worrying about any negative health consequences down the road.
