Caffeine, which is flavorless and can be found naturally in scores of plants, is found in tea leaves, kola nuts, coffee and cocoa beans. Caffeine is also present in some soft drinks as well as energy drinks. It is frequently added to over-the-counter medications such as pain relievers, appetite suppressants and cold medicines. It is so ever-present that you may be consuming more caffeine than you think, even if you don't drink coffee, tea or cola.

Caffeine and Hydration
Common wisdom once had it that if you drank caffeinated beverages, you would urinate more than if you only drank caffeine-free drinks. This has been found to untrue, according to MayoClinic.com. Unless you consume four to seven cups, or more than 500 to 600 milligrams, of caffeine per day, you are not at risk for dehydration.
Caffeine and LDL Cholesterol
If you have diabetes and have difficulty controlling your blood sugar, it may be beneficial for you to switch from caffeinated to decaffeinated coffee, as reported by Harvard School of Public Health. Caffeine may lower your sensitivity to insulin. If you feel sluggish during the day, and you tend to drink a caffeinated beverage rather than doing some form of exercise, you may be at risk of gaining weight. You may also be increasing your risk of heart disease.
Caffeine and Bone Health
If you must drink caffeinated beverages, then add low-fat milk for some extra calcium. If you receive an adequate amount of daily calcium, and consume a moderate amount of caffeine, your risk for osteoporosis will probably not be affected by your caffeine intake, according to the Health Canada website.
