What You Need to Know about Caffeine?
There in the general population myths about caffeine, of which some are true, but many others, fortunately, are not:
“A coffee after a meal aids digestion”
Caffeine stimulates the secretion of saliva and gastric juices and helps digestion, but there is something more interesting: the consumption of coffee reduces the appearance of gallstones, according to a study released in June 1999 in the Journal of the American Medical Association.
According to researchers at Harvard University, adults who drink two to three cups of caffeinated coffee are 40 percent less likely to suffer from that ailment. It appears that caffeine can prevent crystallization of cholesterol, the main component of gallstones. However, specialists have refused to recommend increasing coffee consumption because of the negative consequences that may have on other aspects of health.
“Caffeine interferes with the activity of drugs”

Caffeine reduces the sedative effect of certain tranquilizers and, if taken with certain antidepressants, can cause a serious crisis of hypertension and heart rhythm disturbances.
“Parents should stop their children drink coffee”
According to the statement by Dr. Judith Rapoport, chief of child psychiatry at the National Institute of Mental Health in the U.S., almost any child reacts adversely with lots of caffeine consumed so typical. She advises parents “to apply common sense to give their children normal servings of caffeinated foods and beverages, including soft drinks and tea,” and adds: “I remain skeptical of any statement to the effect that caffeine causes hyperactivity in children, based on our own research and the weight of scientific evidence. ”
“Expectant mothers can not consume caffeine
Research indicates that moderate consumption does not cause adverse health effects for pregnant women, and does not affect fertility. Dr. James Mills, chief of pediatric epidemiology section at the National Institute of Child Health and Human Development U.S., says: “We have a large database on caffeine in pregnancy from different studies.
Overall, the data reinforce the safety of moderate consumption of caffeine during pregnancy. ” In the case of pregnant women who wish to consume foods and drinks containing it, Mills recommends 300 milligrams daily as a safe level of caffeine, the amount in three to five cups of coffee or more cans of soda.
“Caffeine causes disease in the breast”
Both the Council on Scientific Affairs American Medical Association and the NCI (National Cancer Institute) concluded that there is no relationship between caffeine intake and fibrocystic breast disease -benign disease presenting as lumps, so says Dr. Laurie Green, Gynecological Pacific Medical Center in California.
“Caffeine is dangerous as drugs become addicted”
While cocaine and heroin are highly addictive drugs and cause serious health effects in the social and psychological level there is evidence to suggest that caffeine leads to similar results, says Dr. Charles O’Brien, chief of psychiatry at the Center Veterans Administration Medical and professor of psychiatry at the Medical Faculty of the University of Pennsylvania.
In the strict medical sense, the “addiction” to caffeine would consume in an abusive way. Once people reach their normal daily level of caffeine, usually do not want to eat more, and almost nobody has problems when it reduces its consumption in the course of several days rather than all at once, says O ` Brien.
“Caffeine raises blood pressure and damages the heart”
It has been shown that moderate intake is an increase in tension, but for a short period, and that does not increase the risk of stroke and heart disease. But according to a study published in the American Journal of Hypertension, caffeine, along with stress raise blood pressure and those with hypertension experience greater risk. Like any stimulating substance, which must not be abused, resulting in a state of hyperactivity body at all levels, including cardiovascular, by the secretion of catecholamines.

Exceeding these values is considered doping, because it improves physical performance.
Caffeine is found in many influenza prepared in association with other drugs. It can be used in the treatment of migraine because it produces vasoconstriction in pericranial vessels dilated.
Given the varied and extremely powerful effects of caffeine, and its extensive use in all social strata, may someday be considered the more general restriction of its use as a home to preventive health care. Indeed, increase public education to aid recognition of substances frequently consumed and socially accepted as tea, coffee, alcohol and recreational drugs snuff contain important to help the public distinguish between the types and patterns of consumption.
