Over 4 in 5 Brits fail to connect tea with these 5 science-backed health benefits: Tea Advisory Panel Reports
Experts share 5 benefits of a brew in time for International Tea Day - 21st May
LONDON, May 20, 2025 /PRNewswire/ -- Every year, the 21st of May marks International Tea Day - a day the United Nations has designated as an opportunity to celebrate not only tea's cultural heritage and importance to economies around the world, but also the health benefits that come from brewing up.
This year it coincides with the publishing of a new real-world research survey([1]) of over 1,000 Brits, reviewed by the Tea Advisory Panel (TAP; www.teaadvisorypanel.com). The survey results shine a harsh light on our lack of knowledge of the health benefits of regular tea drinking, with over four in five Brits failing to make the link between their daily cuppa and benefits to their heart health, brain health, bone health, mental health, and sleep.
1. Heart and blood vessel health"The new TAP review reveals worrying
insights into people's perceptions surrounding the health benefits of
enjoying several daily cuppas," comments Registered Dietitian and TAP
member Dr Carrie Ruxton, continuing, "For example, 84% didn't associate
drinking tea with improving heart health and 83% didn't associate it with
lowering blood pressure."This is despite the latest scientific evidence
backing up this benefit. For example, a recent meta-analysis of
randomised controlled trials - the gold standard of scientific evidence -
found that foods rich in specific polyphenols, called flavan-3-ols,
considerably lower raised blood pressure and improve blood vessel
function.(([2])) A major source of these polyphenols is tea."This super
study on dietary sources of flavan-3-ols provides evidence that including
tea in the diet is a good way to help prevent heart disease - the number
one global killer,"(([3])) says fellow TAP member and tea expert Dr Tim
Bond, adding, "What's more, the publishing of the new TAP review in line
with International Tea Day highlights the fact that we have an important
job to do in raising awareness of the health benefits of a brew this
year. Too few people know that popping on the kettle can have a
far-reaching effect on their wellbeing."
2. Relaxation and sleepIn addition to heart health, there are also benefits
relating to how well we sleep but 87% didn't make the link between
drinking tea and improved sleep.Fellow TAP member, researcher and
nutritionist, Dr Emma Derbyshire comments, "This poor knowledge of tea's
potential in helping us get a good night's rest - essential to overall
good health - comes despite solid science to back up the link. For
example, a recent super study of human trials and mechanistic studies
found a growing body of evidence that just one or two cups of tea a day,
including green, oolong, and herbal infusions, could help support sleep
and help us to relax."(([4]))
3. Mental healthScientific evidence that tea supports our mental health is
also stacking up. Yet, 67% didn't associate drinking tea with reducing
stress or anxiety and 86% didn't make the connection between tea drinking
and easing low mood or depression."People simply aren't aware of the
science despite the potentially grave consequences for our physical and
mental health," says Dr Carrie Ruxton, adding, "For example, a recent
review of the latest scientific evidence suggests that certain active
ingredients in tea could help reduce the effects of depression, anxiety,
and sleep problems. These substances include L-theanine, -aminobutyric
acid (GABA), arginine, catechins, theaflavins, caffeine, theacrine, and a
number of volatile compounds."(([5]))
4. Brain health"When it comes to keeping our brain healthy, a study of more
than 4,000 people found that regular tea drinking was significantly
associated with a lower chance of having cognitive impairment in middle
age and older age," explains Dr Tim Bond.Cognitive impairment is an
umbrella term for problems with memory, understanding, reasoning, and
problem-solving. Frequent tea drinking and drinking green tea in
particular were noted to be especially beneficial in this study.(([6]))
However, 91% of TAP study review respondents didn't make the connection
between drinking tea and better cognitive health.
5. Bone healthResearch also shows that tea is supportive of our skeletal
system. For example, as Dr Bond Tim explains, "A super study of 18
individual studies involving more than 48,000 postmenopausal women found
that drinking tea resulted in higher bone mineral density around the
hips. Drinking tea also lowered their risk of osteoporosis and bone
fractures."(([7]))Despite this scientific evidence to back tea's bone
supporting capabilities, when polled, 94% of respondents to the latest
TAP data review didn't associate drinking tea with supporting bone
health.Dr Carrie Ruxton concludes, "The latest TAP data review
demonstrates how much of a worrying knowledge gap exists between Brits'
understanding of the health benefits of a brew and the latest scientific
research. International Tea Day is a chance for us to raise awareness of
the boost we can all give to the health of our hearts, brains, and bones
- as well as to reducing our risk of poor sleep and mental health
problems - simply by sticking the kettle on for a regular cuppa
throughout the day."
The Tea Advisory Panel: The Tea Advisory Panel is supported by an unrestricted educational grant from the UK TEA & INFUSIONS ASSOCIATION, the trade association for the UK tea industry. The Panel has been created to provide media with impartial information regarding the health benefits of tea. Panel members include nutritionists; dieticians and doctors.
