A recent study reveals that caffeine may increase symptoms of menopause in postmenopausal women.
In another study, researchers found that drinking black tea could decrease cholesterol levels.

About 85 percent of women suffer through hot flashes during menopause – symptoms that often start in the head and face before working their way down to the neck and other body areas. Red blotches can pop up on the skin, and these symptoms can come any time, day or night. Night sweats and hot flashes can cause sleep loss, which leads to fatigue and mood changes among sufferers.
The Standard reported that a recent study conducted from 2005 to 2011 at the Mayo Clinic surveyed 2,507 women with menopausal symptoms. Data from 1,806 of those women was included in the final analysis.
Researchers reported that women who consumed caffeine had dramatically higher rates of symptoms, such as hot flashes and night sweats, compared to women who did not take in caffeine. The authors said their findings were significant – even after they adjusted data to take smoking and menopause status into account.
Researchers concluded that caffeine use, including regular coffee drinking, is connected to an increase in hot flashes and night sweats. That suggests that cutting back on caffeine use could lead to decreased symptoms. The authors said more research on the relationship is needed.
In another study, the Standard reported on the potential effects of black tea in relation to cholesterol levels.
The study found that drinking black tea could decrease cholesterol.
Black tea comes from the dried leaves of Camellia sinensis, a shrub most often found in southeast Asia. Black tea, green tea and oolong tea all derive from the same plant, with black tea a favorite and traditional beverage in Great Britain.
Tea quality often depends on age of the tea leaves. Conflicting evidence exists on whether black tea helps to prevent cardiac disease and cancer.
In the recent study, the Standard reported that researchers performed a comprehensive search of medical literature to identify studies that evaluated the effects of black tea on low-density lipoprotein, which is LDL or bad cholesterol; high-density lipoprotein, which is HDL or good cholesterol; and overall total cholesterol.
Ten studies that examined 411 subjects were ultimately used.
Researchers reported that drinking black tea dramatically reduced LDL cholesterol – but not total cholesterol, or the HDL cholesterol. In fact, the LDL cholesterol-lowering effect was higher in those subjects with a higher risk of heart disease.
The study’s authors reported that drinking black tea decreases LDL cholesterol without impacting HDL, and may be helpful to people with increased risks of heart disease.
In addition to examining black tea, research suggests that green tea may lower cholesterol levels, but the number of studies in those with high cholesterol is limited.
More study of people who have this condition is necessary before firm conclusions can be made, officials said.
