FutureStarrHow much caffeine is in a coffee
Coffee is a miracle beverage that has heightened physical and mental alertness, kept millions of people hopping all day, and helped keep workers productive. But what is it actually made of? Is it true that coffee has caffeine in it? You need to know, because the science of caffeine is interesting.According to scientists at the FDA, caffeine can be part of a healthy diet for most people, but too much caffeine may pose a danger to your health. Depending on factors such as body weight, medications you may take, and individual sensitivity, “too much” can vary from person to person.
Many packaged foods, including beverages and dietary supplements containing caffeine, voluntarily provide information on the label as to how much caffeine they contain. Consumers should take care when consuming for the first time a new packaged food containing added caffeine if the amount of caffeine in the food is not declared on the label. Certain conditions tend to make people more sensitive to caffeine’s effects, as can some medications. In addition, if you’re pregnant, trying to become pregnant, or breastfeeding, or are concerned about another condition or medication, we recommend talking to your health care provider about whether you need to limit caffeine consumption.
Q: Are some foods naturally caffeine-free? A: The FDA has not tested a wide variety of common foods to determine if.If you’re used to drinking caffeine-containing beverages every day, and want to cut back, it’s best to do so gradually. Stopping abruptly can cause withdrawal symptoms such as headaches, anxiety, and nervousness. Unlike opioid or alcohol withdrawal, caffeine withdrawal is not considered dangerous, but it can be unpleasant. You may want to talk to your health care provider about how to cut back.

Some from these religions believe that one is not supposed to consume a non-medical, psychoactive substance, or believe that one is not supposed to consume a substance that is addictive. The Church of Jesus Christ of Latter-day Saints has said the following with regard to caffeinated beverages: " . . . the Church revelation spelling out health practices (Doctrine and Covenants 89) does not mention the use of caffeine. The Church's health guidelines prohibit alcoholic drinks, smoking or chewing of tobacco, and 'hot drinks' – taught by Church leaders to refer specifically to tea and coffee."
Caffeine works by stimulating the central nervous system, heart, muscles, and the centers that control blood pressure. Caffeine can raise blood pressure, but might not have this effect in people who use it all the time. Caffeine can also act like a "water pill" that increases urine flow. Caffeine is possibly unsafe when used for a long time or in doses over 400 mg daily. Caffeine can cause insomnia, nervousness, restlessness, nausea, increased heart rate, and other side effects. Larger doses might cause headache, anxiety, and chest pain. (Source:Caffeine is likely unsafe when used in very high doses. It can cause irregular heartbeat and even death.
