Researchers believe that the humble cuppa, packed with health-giving antioxidants, can help prevent the two killer conditions in a triple-pronged attack.
Regular consumption of tea is claimed to prevent artery-blocking blood clots, control blood pressure and stop arteries from dangerously constricting and inhibiting blood flow.
All three conditions can set off a killer heart attack as blood vessels feeding oxygen to heart muscles become blocked.
An extensive review of 40 research papers by Dr Carrie Ruxton and Dr Pamela Mason evaluated a raft of data linking black tea and disease prevention.
The study found that in most cases black tea was found to produce a significant protective association.
Dr Ruxton and Dr Mason estimate that people who drink three to six cups of tea a day lower their risk of contracting heart disease by 30 to 57 per cent compared with people who never drink it or who drink small amounts.
"Given the available evidence to date, regular black tea consumption is linked with a reduced risk of cardiovascular disease and Type 2 diabetes," the Daily Express quoted Dr Ruxton as saying.
"Though the amount required to produce such benefits should be the subject of further research, three to six cups of black tea daily appears to contribute to cardiovascular health.
"These beneficial findings are thought to be due to a variety of positive factors in black tea, such as antioxidant flavonoids and theanine, which help to control blood pressure, regulate nitric oxide production (which impacts on arterial function) and inhibit platelet aggregation (which can cause blood clots).
"Our review also found evidence of a link between black tea consumption and a reduced risk of Type 2 diabetes when one to five cups of tea were consumed daily, depending on the study under investigation," she added.

Washington: A flavonoid found in green tea inhibits the hepatitis C virus (HVC) from entering the liver, a new study has found.
According to German researchers, epigallocatechin-3-gallate (EGCG) may offer an antiviral strategy to prevent HCV reinfection following liver transplantation.
HCV infection can lead to chronic hepatitis, cirrhosis, and hepatocellular carcinoma (HCC) or primary liver cancer. HCV is one of the most common causes of chronic liver disease and a primary indication for liver transplantation, affecting up to 170 million individuals worldwide according to estimates from the World Health Organization (WHO).
While standard treatment with interferon with ribavirin and newer protease inhibitors may clear infection in some individuals, a substantial number of patients still may not respond to these therapies.
For individuals receiving liver transplants due to complications from HCV, reinfection of the healthy donor liver remains a significant concern. Antiviral strategies that target HCV in its early stages are urgently needed to prevent graft reinfection and improve long-term outcomes for patients.
To address this critical issue, Sandra Ciesek and Eike Steinmann from the Hannover Medical School in Germany investigated the effect of the EGCG molecule in preventing HCV from attaching to liver cells.
“Green tea catechins such as EGCG and its derivatives epigallocatechin (EGC), epicatechingallate (ECG), and epicatechin (EC) have been shown to exhibit antiviral and anti-oncogenic properties,” Ciesek said.
“Our study further explores the potential effect these flavonoids have in preventing HCV reinfection following liver transplantation,” she said.
Results showed that unlike its derivatives, EGCG inhibits entry of HCV into liver cells. The authors suggest that EGCG may impede HCV cell entry by acting on the host cell as the green tea catechin was not found to alter the density of virus particles.
Pretreatment of cells with EGCG before HCV inoculation did not reduce the infection, however, application during inoculation inhibited the rapid spread of the HCV.
Lastly, researchers showed that EGCG inhibits viral attachment—the initial step in the HCV infection process.
“The green tea antioxidant EGCG inhibits HCV cell entry by blocking viral attachment and may offer a new approach to prevent HCV infection, particularly reinfection following liver transplantation.” Ciesek added,

New Delhi: Green tea may be effective in reducing `bad cholesterol`, a study has found.
Green tea contains antioxidant compounds called catechins, which many studies have tested for their effect on cholesterol even though the studies have been small and had conflicting results.
For the new study researchers at Western University of Health Sciences in Pomona, California, pooled the results of these clinical trials, involving a total of 1,415 adults.
Participants in the trials consumed green tea beverages, capsules, or placebos daily. Benefits were found among people who had high cholesterol levels at the beginning of the study.
However, the researchers still sound a word of warning.
"If someone is already taking medication for their cholesterol, they should stick with it and not try to trade it for green tea, either capsules or the beverage," CBS news quoted study author Dr. Olivia Phung as saying.
According to the study, the use of herbal supplements like green tea is only one of the strategies to lower cholesterol, along with medication and lifestyle changes.
