Osteoporosis is not a women-specific disease, but it occurs mostly in women. Factors contributing to osteoporosis include calcium and protein intake, smoking, exercise habits, age and weight. To gain insight into the relationship between caffeine intake and osteoporosis, researchers must carefully grasp each variable.

A 1994 Barrett Connor study found that caffeine intake affected bone density reduction only in women who were restricted to a glass of milk a day during adulthood. According to the study, and as a rule of thumb, coffee only indirectly causes calcium imbalance-for example, some women substitute it for calcium-rich beverages.

Barger-Lux and Heaney concluded from a 1995 analysis of data from 190 women that "one cup of milk provides enough calcium to offset the negative effects of eight cups of caffeine...," underscoring the fact that caffeine is not a high risk factor for osteoporosis, and that insufficient calcium intake is the primary cause, as well as secondary factors such as caffeine.

A 1981 Harvard University report suggested that drinking too much coffee could lead to pancreatic cancer. However, at least seven major studies have since failed to confirm this, so the researchers retracted this conclusion. Several other studies have failed to prove a link between coffee drinking and breast cancer. Heavy coffee consumption appears to reduce the risk of colon cancer, with people who drink at least five cups of coffee a day 40 percent less likely to develop colon cancer than non-coffee drinkers, according to a Boston University study.

Coffee has the effect of eliminating garlic flavor, but also contains enamel, so after tasting garlic dishes, coffee is an indispensable drink.

A 1980s study found that men who drank five or more cups of coffee a day for long periods of time were more likely to suffer from heart disease. But recent studies have found that women who drink less than five cups of coffee a day don't have an increased risk of heart disease, and women who drink more than six cups a day don't seem to have an increased risk of heart attack.

Coffee also has a deodorizing effect. The residue of ground coffee brewing is dried in a container, placed in the refrigerator, or in a shoe box as a deodorizing agent. Sprinkle it in an ashtray to eliminate tobacco smell.

Coffee can also be used to hide flavor. For example, instant coffee is dissolved in boiling water, so that its taste can be more sweet and delicious meat dishes.

Fragrant coffee is a refreshing drink, and the latest research also found that drinking a few cups of coffee a day can prevent gallstones.

Harvard University researchers found that men who drank two to three cups of coffee a day had a 40 percent lower risk of developing gallstones than non-coffee drinkers, while men who drank four or more cups of coffee a day had a 45 percent lower risk of developing gallstones, the Journal of the American Medical Association reported. However, caffeine-free coffee can not have this effect, only caffeinated coffee, in order to stimulate gallbladder contraction, and reduce cholesterol in bile easy to form gallstones. As for the reason for the effect of coffee, it is still unclear, and other beverages such as tea and cola, which also contain caffeine, cannot achieve the same effect because the caffeine content is lower than coffee.

Dr. Leitzman, who led the study, said: "I wouldn't really recommend drinking coffee to prevent gallstones, but it's okay to keep drinking coffee because coffee doesn't cause any major diseases." He said the findings should also apply to women.

Cholelithiasis is mainly formed by cholesterol, and lack of exercise, greasy diet or excessive weight are the main causes.
