Are you the type of person who needs to have their latte, cappuccino or macchiato in the morning? Do you need an energy drink to keep you alert during your work day? One thing these drinks all have in common is caffeine. Caffeine is a natural stimulant that is commonly found in coffee and energy drinks, but is also present in tea, cacao plants and some medications. It is recommended that caffeine intake not exceed 400 milligrams a day, according to Julia Zumpano, a dietitian from Cleveland Clinic. Depending on your tolerance for caffeine, you might not realize the effects it may be having on your body.

Caffeine is a central nervous system stimulant and binds to adenosine receptors in your central nervous system. Adenosine is what helps you feel drowsy when it’s time to go to sleep. Caffeine can interact with the same brain receptors as adenosine and block the hormone, leading you to feel awake and alert.

There are many things that pregnant women should add to their diet, but caffeine isn’t one of them. Caffeine is not recommended if you’re pregnant given it can elevate blood pressure and heart rate. Even though you may have great tolerance for caffeine, your baby does not. Your baby’s metabolism is still maturing and this can affect their sleep or movement patterns in later stages of pregnancy.

Be mindful of how much caffeine you ingest because there is a study that shows it may interfere with calcium absorption. Because high consumption of caffeinated beverages have been linked to lower milk intake, it may lead to reduced bone mass and increase your risk of fractures. However, on its own, the negative effect of drinking caffiene is small enough to be fully offset by as little as a few tablespoons of milk. Make sure you take a look at recipes that use milk and try to incorporate them into your diet.

There is research that shows that caffeine intake can reduce the risk of kidney stones. Since caffeine is diuretic, meaning it helps you urinate frequently, it can increase urinary calcium excretion and prevent crystallization of calcium stones and other stones that can form in your kidneys. However, drinking too much caffeine can lead to kidney stones. Kidney stones are also a surprising sign you’re eating too much salt. You must keep a healthy balance of water intake while consuming caffeine to help increase urinary calcium excretion.
