Drinking Black Tea Shows No Impact on
Cardiovascular Risk Factors
It is commonly believed that polyphenol antioxidants, found in tea, have a variety of health benefits, including cardiovascular benefits. However, randomized trials to date have yielded mixed results on the effects of tea on cardiovascular risk factors.
To address inconsistencies in previous studies and to determine if there are effects of moderate tea drinking on cardiovascular risk factors, Kenneth J. Mukamal, M.D., M.P.H, M.A., and colleagues conducted a small, six-month, randomized clinical trial. The study included 28 adults, 55 years and older, who were at an increased risk for cardiovascular disease.
Researchers compared two groups of 14 participants, who were assigned to drink three glasses daily of either a standardized black tea preparation or water. After six months, research data showed that there were no significant differences between the tea group and the water group on advanced cardiovascular risk biomarkers, such as metabolic factors, lipid levels, markers of inflammation, and systolic blood pressure.
It should be noted that not all pathways to cardiovascular disease were measured in the study. Also, although the black tea used in the study contained ample polyphenol content, doses given to participants were smaller than in some previous studies. The researchers believe their study is the longest such trial conducted to date, but concluded that confirmation of the effects of black tea on cardiovascular risk will require larger and longer studies in more diverse populations.

Abstract
OBJECTIVE: A number of potential health effects have lately been accorded to tea consumption. It is, however, not clear whether an increase in tea consumption increases the risk of iron depletion in a normal apparently healthy adult population. We have therefore evaluated this.
DESIGN: Cross-sectional study.
SUBJECTS: A total of 954 men (aged 52-68 years) and 1639 women (aged 42-68 years), who were participants of SU.VI.MAX Study, completed a detailed questionnaire on tea consumption. To determine the iron status of the participants, a venous blood sample was drawn and serum-ferritin was measured. Iron depletion was defined as a serum ferritin concentration <16 microg/l. Three 1-day food records were used to estimate the intake of other dietary enhancing or inhibiting factors of iron absorption, which were included in the logistic regression models.
RESULTS: The mean serum-ferritin concentration was not related to black, green and herbal tea consumption in men, pre- or postmenopausal women. Also the risk of iron depletion was in the multivariate model not related to any kind of tea drinking or to the strength of tea, the infusion time or the time of tea drinking.
CONCLUSIONS: The data suggest that normal apparently healthy adults are not at risk of iron depletion owing to any kind of tea drinking.
