Iron deficiency anemia due to excessive green tea drinking
Key Clinical Message
Tea interferes with iron absorption and can lead to iron deficiency anemia when consumed in large quantities. The rechallenge effect of green tea on anemia in a middle‐aged man emphasizes the potential causal role of this beverage. Lifestyle and dietary habits are important diagnostic considerations in diseases of this type.

Quality assessment of marketed chamomile tea products by a validated HPTLC method combined with multivariate analysis
Publication date: 5 January 2017 Source:Journal of Pharmaceutical and Biomedical Analysis, Volume 132 Author(s): Etil Guzelmeric, Petar Ristivojević, Irena Vovk, Dušanka Milojković-Opsenica, Erdem Yesilada Chamomile tea composed of dried flower heads of Matricaria recutita L. (Asteraceae) is one of the most popular single ingredient herbal teas. Tea industries, spice shops or public bazaars are mostly supplied chamomile as a raw material via cultivation or through nature-picking. However, one of the drawbacks of nature-picking is adulteration. This could be either due to false authentication of the plant material...

Molecules, Vol. 21, Pages 1305: Beneficial Effects of Tea and the Green Tea Catechin Epigallocatechin-3-gallate on Obesity
Green tea has been shown to have beneficial effects against cancer, obesity, atherosclerosis, diabetes, bacterial and viral infections, and dental caries. The catechin ( −)-epigallocatechin-3-gallate (EGCG) has shown the highest biological activity among green tea catechins (GTCs) in most of the studies. While several epidemiological studies have shown the beneficial effects of tea and GTCs on obesity, some studies have failed to do this. In addition, a large numb er of interventional clinical studies have shown these favorable effects, and cellular and animal experiments have supported those findings, and revealed the u...

Experimental StudyBIO-TEA PREVENTS MEMBRANE DESTABILISATION DURING ISOPROTERENOL INDUCED MYOCARDIAL INJURY
Publication date: Available online 26 September 2016 Source:Journal of Microscopy and Ultrastructure Author(s): Reema Orison Lobo, K. Chandrakala Shenoy The present study is undertaken to determine the membrane stabilizing effect of Bio-tea in the prevention of myocardial injury caused by Isoproterenol in rats. The efficiency of Bio-tea pre-treatment was compared against black tea pre-treatment and the positive control (Isoproterenol induced myocardial infarcted rats) and negative control (normal control rats). For this purpose, biochemical analysis of the in vivo antioxidants (superoxide dismutase, catalase, and reduc...

Inhibition of MMP-9 by green tea catechins and prediction of their interaction by molecular docking analysis
Publication date: December 2016 Source:Biomedicine & Pharmacotherapy, Volume 84 Author(s): Jaganmay Sarkar, Suman Kumar Nandy, Animesh Chowdhury, Tapati Chakraborti, Sajal Chakraborti Green tea polyphenolic catechins have been shown to prevent various types of diseases such as pulmonary hypertension (PAH), cancer and cardiac and neurological disorders. Matrix metalloproteinases (MMPs) play an important role in the development of PAH. The present study demonstrated that among the four green tea catechins (EGCG, ECG, EC and EGC), EGCG and ECG inhibit pro-/active MMP-9 activities in pulmonary artery smooth musc...

Hypolipidemic effects of crude green tea polysaccharide on rats, and structural features of tea polysaccharides isolated from the crude polysaccharide.
Authors: Nakamura M, Miura S, Takagaki A, Nanjo F
Abstract
Crude tea polysaccharide (crude TPS) was prepared from instant green tea by ethanol precipitation followed by ultrafiltration membrane treatment and its effects on blood lipid, liver lipid, and fecal lipid levels were examined with Sprague-Dawley rats fed a high-fat diet. Although crude TPS showed no effects on the serum lipid levels, it suppressed the liver lipid accumulation and increased the fecal excretion of dietary fat. Then, the structural features of crude TPS were investigated. After separation of crude TPS by DEAE-cellulose and gel-filtra...

Design of capacitance measurement module for determining critical cold temperature of tea leaves
Publication date: Available online 22 September 2016 Source:Sensing and Bio-Sensing Research Author(s): Yongzong Lu, Yongguang Hu, Eric Amoah Asante, Francis Kumi, Pingping Li Critical cold temperature is one of the most crucial control factors for crop frost protection. Tea leaf's capacitance has a significant response to cold injury and appears as a peak response to a typical low temperature which is the critical temperature. However, the testing system is complex and inconvenient. In view of these, a tea leaf's critical temperature detector based on capacitance measurement module was designed and developed to mea...

Green tea polyphenolic catechins have been shown to prevent various types of diseases such as pulmonary hypertension (PAH), cancer and cardiac and neurological disorders. Matrix metalloproteinases (MMPs) play an important role in the development of PAH. The present study demonstrated that among the four green tea catechins (EGCG, ECG, EC and EGC), EGCG and ECG inhibit pro-/active MMP-9 activities in pulmonary artery smooth muscle cell culture supernatant. Based on the above, we investigated the interactions of pro-/active MMP-9 with the green tea catechins by computational methods. In silico molec...

Tea flavonoids for bone health: from animals to humans
Osteoporosis is a skeletal disease characterized by a deterioration of bone mass and bone quality that predisposes an individual to a higher risk of fragility fractures. Emerging evidence has shown that the risk for low bone mass and osteoporosis-related fractures can be reduced by nutritional approaches aiming to improve bone microstructure, bone mineral density, and strength. Tea and its flavonoids, especially those of black tea and green tea, have been suggested to protect against bone loss and to reduce risk of fracture, due to tea's antioxidant and anti-inflammatory properties. Based on the results of animal studies, ...

Trends in fluid consumption and beverage choices among adults reveal preferences for ayran and black tea in central Turkey
ConclusionsOlder participants prefer healthy, traditional choices such as ayran and black tea, but younger participants prefer high energy‐containing drinks with low nutritional value. Thus, this unique information contributes to the data on beverage consumption patterns in different countries and might be useful for increasing consumption of nutritious fluids and decreasing sugar usage in Turkey.

Layer ‐by‐Layer Thin Film of Iron Phthalocyanine as a Simple and Fast Sensor for Polyphenol Determination in Tea Samples
Abstract
Polyphenols have attracted attention due to their antioxidant capacity and beneficial effects to health. Therefore, fast, inexpensive, and efficient methods to discriminate and to quantify polyphenols are of interest for food industry. In this paper, Layer‐by‐Layer films of poly(allylamine hydrochloride) and iron tetrasulfonated phthalocyanine were employed as sensor for determination of polyphenols in green tea (camellia sinensis), and green and roasted mate teas (ilex paraguariensis). The polyphenol sensor was tested in catechol standard solution by differential pulse voltammetry (DPV), reaching a limit of d...
