The Buzz on Caffeine

Health Benefits and Risks of Caffeine Consumption

4 Health Risks of Caffeine Consumption
  • Complex Tasks: Caffeine can worsen performance on complicated tasks, and with caffeine usage over time, the mental boost one gains from caffeine is reduced.
  • Fertility and Pregnancy: The March of Dimes recommends that women who are pregnant or trying to get pregnant consume no more than 200 milligrams of caffeine per day due to possible adverse effects on fertility, miscarriage and fetal growth.
  • Fibrocystic Breast Disease: While it does not cause this condition, caffeine can aggravate the symptoms in some women who already have the disease. 
  • Sleep: Consumed later in the day, caffeine can interfere with the onset of sleep and especially rapid eye movement (REM) sleep. Most people report difficulty falling asleep when consuming caffeine within six hours before going to bed. Your sensitivity will vary based on how quickly your body metabolizes caffeine, the amount you ingest and your regular consumption amount.  
6 Things Caffeine Has NO Affect On
  • Cancer: Current research does not show a link between caffeine intake and cancer in humans. 
  • Dehydration: Caffeine is a mild diuretic that can increase the frequency of urination. However, the fluid you consume in the caffeinated beverage tends to offset the fluid loss when you urinate. Studies have shown that caffeinated beverages do not cause dehydration. 
  • Heart Disease or High Blood Pressure: Caffeine has not been shown to increase the risk for cardiac arrhythmias, coronary heart disease, stroke or the development of chronic hypertension. It has not been shown to increase cholesterol levels or alter lipid profile.
  • Osteoporosis: Caffeine has not been shown to be a risk factor in the development of osteoporosis, especially in adults with adequate daily calcium intake. It does not alter calcium absorption or excretion significantly.
  • Reduced Intoxication: When intoxicated from too much alcohol intake, caffeine does not "sober you up" faster.
  • Weight Loss: Because caffeine is a stimulant, it does speed up metabolism, but the effect is only minimal and very short term. Clinical research does not show a significant weight loss with the use of caffeine-containing supplements. Therefore, save your money and leave those supplements (which can contain up to 300 mg of caffeine per dose) on the store shelf.   Continued ›
