Need your morning fix? Learn the pros and cons of caffeine and how much is too much
- 2 Minutes Read
The pros and cons of caffeine still get debated in medical and nutrition circles alike. It's the world's most commonly consumed drug, with 80 percent of Americans using caffeine daily. Learn some surprising caffeine benefits and potential downsides.
Caffeine indeed offers the boost that many of us look for, such as increasing mental alertness, especially among only occasional users.
Caffeine can help migraine and tension headache sufferers, especially when included with pain medication. The US Food and Drug Administration (FDA) has approved caffeine for these uses.
Athletes often turn to caffeine as a sports performance aid, providing a slight increase in athletic strength and endurance. The National Collegiate Athletic Association limits the level of caffeine detected in collegiate athletes' urine.
Coffee and tea drinkers tend to have a lower risk of type 2 diabetes. However, caffeine's effects on people with existing diabetes appear mixed.
According to an extensive review published in the British Medical Journal, coffee drinkers have a lower risk of liver cancer, fatty liver disease, and gallbladder disease.
You may feel better about grabbing that extra cup of coffee, knowing these potential caffeine benefits. Still, they don't show cause and effect. There's no reason to start drinking caffeinated beverages if you don't care for them or like how they make you feel.
Will caffeine help you lose weight? Coffee drinkers tend to have a slightly lower BMI, but there is inconsistent evidence for caffeine lowering one's appetite. A review of green tea studies found an association between green tea consumption and decreased body weight and body fat.
If your favorite coffee drink is full of cream and sweeteners, or you must pair baked goods with your mid-morning coffee, caffeinated coffee won't help your weight-loss goals.
You may notice caffeine pitfalls, even if you only drink a cup or two of coffee or tea. Common caffeine side effects include rapid heartbeat, jitteriness, and sleep difficulties. Digestive side effects include diarrhea and heartburn.
Caffeine may cause frequent urination and bladder irritation. Despite popular belief, caffeine does not cause dehydration for regular users.
Any long-term coffee drinker knows that caffeine is habit-forming. If you choose to give up caffeine, do so gradually to avoid the misery of caffeine-withdrawal headaches.
The British Journal of Medicine review concluded that there are no significant health risks with caffeine intake up to 400 mg (about 4 cups of coffee) per day in healthy adults. Likewise, the FDA states that up to 400 mg of caffeine is not associated with dangerous side effects.
Do you find yourself jittery after just one cup of coffee while your friend can drink a pot with no problem? Genetics may explain the difference. How people process caffeine varies significantly. Blood caffeine levels usually peak about one to two hours after consumption. The rate at which people break down half of the caffeine in their body can range from two to ten hours. Caffeine can also affect people differently based on their tolerance and usual intake.
