California, October 5, 2017: We have all been suggested to have a cup or two of green tea every day for its multiple health benefits. But are you a tea-lover, who prefers to have black tea over green tea?

Health benefits of black tea are many. Perfectly brewed black tea benefits for skin and hair are also known to many.

“For black tea lovers, there may be a new reason to keep drinking it,” said Dr Zhaoping Li, a senior author of a new study which points out the positive impact of black tea on the energy metabolism of the body.

The animal study has been carried out by a team of researchers at the University of California, Los Angeles (UCLA) and has been published in the European Journal of Nutrition.

As part of the research procedure, mice were given black or green tea along with their diet. Consequently, the intestinal bacteria in mice were observed to measure the effect.

The Research

After four weeks, the weights of the mice that were given green or black tea extracts dropped to the same levels as the mice receiving a low-fat diet.

The mice were divided into four groups with different diets,

  • Low-fat and high-sugar
  • High-fat and high-sugar
  • High-fat and high-sugar supplemented with green tea extracts
  • High-fat and high-sugar supplemented with black tea extracts

Observation

The researchers observed that consumption of tea altered the ratio of bacteria in the mice, showing a decrease in the percentage of bacteria causing obesity and an increase in bacteria that are associated with lean body mass.

Surprisingly, only the mice with black tea extracts diet revealed an increase in a category of gut bacteria called pseudobutyrivibrio which possibly causes the difference in the effects of black and green tea in energy metabolism.

Conclusion

According to researchers, green tea molecules are smaller in size and exercise direct impact on the liver to alter metabolism due to easier absorption.

However, the molecules in black tea are relatively bigger in size, which impede their absorption. Thus, they remain in the intestine, where they promote the development of beneficial bacteria that are involved in the regulation of energy metabolism.

It is a well-known fact that green tea, rich in polyphenols, has multiple health benefits that include weight loss, healthy skin, and developing immunity, among others. However, according to Susanne Henning, lead author of the study, black tea may also contribute to good health and weight loss. She believes, “The results suggest that both black and green teas are prebiotics, substances that induce the growth of good microorganisms that contribute to a person’s well-being.”

Dr Zhaoping Li shared that the health benefits of black tea and green tea are not only limited to their antioxidant qualities. Instead, they also exercise a significantly positive impact on the gut microbiome.

 India has successfully achieved the target of 25 per cent reduction in visual impairment, the latest National Blindness and Visual Impairment Survey 2015-2019 has revealed.

The WHO Global Action Plan for Universal Eye Health 2014-2019 targeted a reduction in the prevalence of visual impairment by 25 per cent by 2019 from the baseline level of 2010.

The current survey shows a reduction of 47.1 per cent in blindness, 52.6 per cent in moderate severe visual impairment (MSVI) and 51.9 per cent in visual impairment (VI) compared to the baseline levels. This is way above the estimates that WHO had set in 2010 and shows that India has successfully achieved the target of 25 per cent reduction in visual impairment

The survey was conducted in order to provide the evidence about the present status of blindness and visual impairment in India. It was planned by the Union Ministry of Health and Family Welfare. Delhi’s Dr Rajendra Prasad Centre for Ophthalmic Sciences at AIIMS was responsible for planning and executing the field work, monitoring, analysis and report writing of the survey. The survey was conducted in partnership with various reputed eye health institutes of the country.

The estimated prevalence in overall population of blind was 0.36 per cent, severe visual impairment was 0.35 per cent, MSVI was 1.84 per cent, early visual impairment was 2.92 per cent. Estimated moderate severe visual impairment in overall population was 2.19 per cent and that of visual impairment was 2.55 per cent. Estimated prevalence of pinhole blindness in overall population of India was 0.32 per cent.

Over the years, the prevalence of blindness among over the 50-year-olds has reduced considerably. Blindness, has reduced from 5.3 per cent in 2001 to 3.60 per cent in 2007 to 1.99 per cent in current survey. Visual impairment has reduced from 32.3 per cent in 2001 to 24.8 per cent in 2007 to 13.73 per cent in current survey in population above 50 years.

Cataract, however, continues to be the major cause of blindness and is responsible for 66.2 per cent of blindness, says the survey. Refractive error was the most important cause of visual impairment and second important cause of blindness in 2001, but the current survey showed that refractive error is not an important cause of blindness now. Corneal blindness emerged as the second important cause of blindness. Beside this, the proportion of blindness due to complications of cataract surgery have also increased.

According to the survey, the prevalence of blindness and visual impairment was lowest in Thrissur district (Kerala) and in Thoubal district (Manipur) respectively. Bijnor district (Uttar Pradesh) had the highest prevalence of both blindness and visual impairment.

Blindness was higher among the illiterate (3.23 per cent) compared to literate population. It was only 0.43 per cent among 10th pass and above.

Blindness was more prevalent in the rural population as compared to urban population at 2.14 per cent versus 1.80 per cent, said the survey.
