There is now even more reason to enjoy a cup of tea with a new review of existing research showing the humble cuppa can help prevent a number of diseases, including Alzheimer’s disease and diabetes.
Researchers from Edith Cowan University’s School of Medical and Health Sciences examined more than 100 studies from around the world that have looked at tea consumption.
They found that black, white and green tea can reduce the risk factors associated with Alzheimer’s disease and diabetes.
The findings could offer some hope to the more than 65 million people expected to be living with Alzheimer’s disease by 2030.
Likewise, some 5.1 million deaths worldwide were attributed to diabetes in 2013, a figure that is growing annually.
ECU Centre for Excellence for Alzheimer’s Disease Research and Care Research Fellow Dr Fernando said the review offered new lines of enquiry for scientists.
“There is strong evidence that tea consumption can lower the levels of beta amyloid b (Aβ) in the brain, the build-up of which can cause Alzheimer’s disease,” she said.
“In particular a number of studies have found that the flavonoid Epigallocatechin gallate (EGCG), which is found in tea, can reduce the levels of Aβ in the brain, which could delay the onset of Alzheimer’s disease,” she said.
Diabetes risk down
The researchers also examined the evidence that tea consumption could be protective against diabetes.
“Both population-based studies as well as human clinical trials have shown a link between tea consumption and a reduced risk of developing Type 2 Diabetes,” Dr Binosha said.
“One study found that drinking tea could result in a significant reduction in the symptoms of diabetes, including a 15-fold increase in insulin activity. Low insulin activity is a major risk factor for diabetes. ”
“Overall, tea appears to offer a safe and acceptable approach toward lowering the risk factors associated with diabetes and Alzheimer’s disease,” Dr Fernando said.
“What is needed now is more randomised, clinical trials which are placebo controlled using standardised doses to determine exactly the manner, type and amount of tea required to achieve these beneficial results.”
ECU’s Centre for Excellence for Alzheimer’s disease Research and Care has also recently identified depression and trouble sleeping as potential risk factors for Alzheimer’s disease.
The Centre is also currently investigating if a combination of the spice circimun and fish oil can potentially delay the onset of Alzheimer’s disease.
‘Diabetes and Alzheimer’s Disease: Can Tea Phytochemicals Play a Role in Prevention?’ was recently published in the Journal of Alzheimer’s Disease.
Carrie Bickmore has won the Twinings Design Challenge with her packaging design remaining on shelf in supermarkets nationally for the next four years.
Ten cents for every pack of Twinings Morning Tea sold will be donated to Carrie’s chosen charity; Carrie’s Beanies 4 Brain Cancer.
Tens and tens of thousands of votes were cast placing Carrie ahead of Emma Freedman, Samantha Harris and Nicole Kidman.
“My design was inspired by my childhood. Music and dance was always a massive part of my life, I was a ballet dancer as a child, and I’m always the first and last on the dance floor,” said Bickmore.
“Music has been my sanctuary through the tougher times of my life, and some of the happy. I thought music and movement would be something Australian women can all relate to.”
“And to be able to continue supporting my charity, Carrie’s Beanies 4 Brain Cancer, helping fund vital research into brain cancer is a phenomenal opportunity – I can’t thank everyone enough who voted for my design, this means the world to me.”
Black, oolong, white and green teas all come from the same plant, Camellia sinensis. The differences come from the harvest timing and processing, particularly the level of oxidation, a reaction that occurs when processed leaves are exposed to high oxygen levels. Black tea is fully oxidized, oolong is partially oxidized, while green and white teas are unoxidized. White teas are from early harvests, green from later.
Interestingly, the pH of water also impacts the extraction process. Low pH (acidic) water extracts bioactives better than high pH (basic) water. The pH of tap water is about seven, which is neutral, so there might be a benefit to adding lemon with your tea, rather than after its brewed.
Tea in the microwave?
The idea of making tea in the microwave is horrifying for purists. It’s argued microwaves are inferior to kettles for heating water, as there is less control over the temperature. But the microwave could actually be a useful tool for extracting more bioactives.
Microwaves can actually increase the levels of bioactives in your cup. Adding freshly boiled water to the teabag, steeping for 30 seconds, followed by a minute in the microwave (medium power) extracts more bioactives than a standard three minute steep.
But others have shown the same level of antioxidants reach the blood after consuming tea with and without milk. There’s no real science behind the age old question of when the milk should be added. The Royal Society of Chemistry suggests adding it first prevents denaturation, or clumping, of milk proteins, which might give the milk a stale taste.
Lower quality teas may also include more stems, which are higher in L-theanine than the leaves. So while fancy loose leaf might taste better, you probably get more bang for buck from a humble tea bag.
Health benefits might not be the only reason we choose to drink tea, but if you want to get the most out of your cup, patience is the key. Whichever type of tea you choose, the longer you brew, the more goodness in each cup.
The top four finalists of the Twinings Design Challenge are Carrie Bickmore, Emma Freedman, Samantha Harris and Nicole Kidman.
Packs of Twinings Morning Tea blend featuring the four designs hit shelves from today. They were chosen by a judging panel including Archibald Prize judge Ashley Dawson-Damer, out of a field of 33 incredible designs.
Ten cents from every pack of Twinings Morning Tea sold will be contributed towards the top four’s charities of choice; Carrie Bickmore – Carrie’s Beanies 4 Brain Cancer, Emma Freedman – Captain Courageous Foundation, Samantha Harris – Make-A-Wish Australia, and Nicole Kidman – Variety: The Children’s Charity.
Australians will have a chance to vote for their favourite design and voting is open, running between now to 8th May.
Whichever celebrity accumulates the most votes will have her design remain on shelf, where 10c from every pack sold will be contributed to her charity of choice over the next four years.
Boutea, a loose leaf tea founded by Australian rugby union player Adam Ashley Cooper, is now available in Australia.
The range consists of four varieties: English Breakfast, Earl Grey, Green Citrus and Peppermint. Whilst the English Breakfast sticks to traditional roots of full-bodied flavour and maple colour, the Earl Grey delivers a strong floral aroma with a well-structured and creamy body.
For fans of herbal teas, the addition of citrus peel balances the earthiness of traditional green tea in the Green Citrus blend whereas the Peppermint delivers a slightly restrained peppermint profile ensuring you can finish the whole cup.
Whilst living in Canberra and playing for the Brumbies, Ashley Cooper discovered his love of tea. Outside of playing, training and sleeping, he and his team mates created a ritual of going to cafés together to socialise off the field.
During this time, he lived next door to tea connoisseur Jody Hillier who introduced him to the many intricacies of the world of tea. Their shared passion for a remarkable brew resulted in a partnership where five years later, Boutea was born.
This premium tea is now available for purchase via the company’s website. As well as the taste, the simple yet classic black and white aesthetics is intended to create a visual point of difference from other teas on the market.
