Compounds in coffee could help to lower risk of type 2 diabetes, study shows
The only thing to get us out of bed on some freezing winter mornings, coffee really is one of life's great luxuries.
Apart from warming and energising us, our daily roast has also been linked to improved heart and brain health, boosting mood, as well as a reduced risk of depression and liver disease.
The list of benefits just keeps on growing, with a new study suggesting black coffee could lower our risk of type 2 diabetes.
According to Diabetes Australia, close to 1.9 million Australians live with diabetes, almost 1.3 million of whom have type 2.
The condition is caused by high blood sugar levels and insulin resistance, and genetics, weight, activity level, a high sugar diet and some disorders can increase people's risk of developing it.
Researchers from Korea pulled together data from close to 150 publications to see if coffee had an effect on the development of type 2 diabetes. They focused on the brew's effect on our pancreas, liver, small intestines, muscle and tissue.

What are polyphenols?
Polyphenols are naturally occurring compounds with anti-inflammatory and antioxidant properties.
Regular intake has been linked to improved digestion, and brain and heart health, and the research team believed these phytonutrients could be behind coffee's potential for reducing the risk of type 2 diabetes.
After their analysis, the scientists suggested that our daily long blacks can help to modulate blood sugar levels, improve insulin sensitivity, reduce inflammation, provide antioxidant properties and boost the metabolism of glucose.

Decaf could provide the same perks
And it's not just full-strength coffee providing benefits either.
According to the findings, decaf drinkers could reap the same rewards.
People who drank coffee regularly had a 20 to 30 per cent lower risk of type 2 diabetes, regardless of caffeine content.
But just the thought of five coffees a day conjures up images of an impending panic attack and scattered thoughts for many of us.
The researchers concluded that 'coffee and its bioactive compounds, including chlorogenic acid and its hydroxycinnamic acid derivatives… have significant potential in the prevention and management of [type 2 diabetes]'.
They found that three to five black coffees daily was the ideal amount to consume to benefit from these perks.
But just the thought of five coffees a day conjures up images of an impending panic attack and scattered thoughts for many of us, and consuming too much caffeine can induce headaches, nausea, insomnia, and the shakes, so don't push yourself to down short blacks all day solely to reduce your diabetes risk.
The team said more research into the health effects of coffee is needed, but if your desk is never without a full mug and you're looking for a reason to maintain your five a day, this could be it.

Online cancer education program provides support for people living with NETs
Online cancer education program provides support for people living with NETs The online course offers support, connection and clarity for people living with NETS and their families. Picture Shutterstock. This is branded content for NeuroEndocrine Cancer Australia. For Australians living with neuroendocrine tumours (NETs) finding reliable information, shared experiences, and a supportive community can make the world of difference. That is exactly what Living with NETs, a free online education program, is designed to provide. Hosted by NeuroEndocrine Cancer Australia, the program returns in mid-July to deliver four virtual sessions that have been specifically designed to help patients and their carers navigate life with NETs. Running from 15 July to 5 August 2025, Living with NETs offers two-hour sessions each Tuesday from 1:30pm to 3:30pm (AEST). The course is free and accessible to any neuroendocrine cancer patients and their carers within Australia with an internet connection. It offers a valuable opportunity for patients and families to gain clarity, connection, and confidence from the comfort of home. What does Living with NETs want to achieve? Living with NETs is a safe, welcoming, and supportive space for people affected by NETs. The program delivers current information and practical guidelines to help people understand a NET diagnosis. It also allows them to more effectively navigate the health system, treatment options, manage daily living challenges, and better communicate with their healthcare team. Each of the four sessions focuses on useful, real-world goals, including: Increasing participants' knowledge of NETs Providing information on tests and treatments Developing strategies for coping with and managing different challenges Providing topics that can assist with life and wellness Encouraging sharing and discussion in a safe setting Building confidence and skills in self-advocating The format includes time for questions, sharing, and discussion, giving participants a chance to hear from others with lived experience and to raise their own concerns in a supportive environment. The Living with NETs online course is a safe, welcoming, and supportive space for people affected by NETs. Picture Shutterstock Why we need programs like this Many current NET patients understand the need for this program. A NET diagnosis can be a frightening and overwhelming event for anyone, including patients, their carers, and their families. NETs are a complex group of cancers that can affect multiple organs and cause a wide range of symptoms. Because they are less common and often misunderstood, people with NETs frequently experience delays in diagnosis or confusion about their treatment. NeuroEndocrine Cancer Australia aims to close this gap by: Promoting self-advocacy, so participants feel more confident making decisions Reducing feelings of isolation through connection with others who understand Building emotional resilience by offering coping strategies and shared stories One of the core benefits of this education is to strengthen the overall healthcare experience ot of NETs by encouraging more proactive engagement from patients and carers. National recognition of NETs Awareness of NETs is growing in Australia thanks to the efforts of NeuroEndocrine Cancer Australia. However, many patients still go undiagnosed for years or receive limited support after diagnosis. National education programs like Living with NETs are part of a push to close the gaps in support, research, education, and advocacy, delivering better future outcomes for patients.

World-first move for gay blood donors
Sexual activity rules that have prohibited thousands of Australians from donating blood have been lifted, smashing long-held stigmas and increasing much-needed plasma supplies. Ever since the AIDS crisis exploded into the public consciousness in the early 1980s, the Australian Red Cross has prevented gay and bisexual men, transgender people, sex workers and people taking pre-exposure prophylaxis (PREP) from donating blood. Decades later, the Red Cross Lifeblood Service reports 'some 625,000 Australians' will become eligible to donate plasma after the lifting of these rules. Australia will become the first country to remove sexual activity wait times for plasma donation and allow those on PREP to donate. NewsWire / John Appleyard Credit: News Corp Australia Lifeblood chief executive Stephen Cornelissen AM said the service was 'looking forward' to welcoming new donors into the fold. 'Importantly, today's (Monday's) change will allow those on PREP to become the first in the world to donate plasma without a wait period,' he said. 'Over the next 12 months, we estimate an extra 24,000 donors will give plasma, but we know people have been eagerly awaiting these changes and hope to far exceed these numbers.' Professor Cornelissen also took time to acknowledge the stigma that has accompanied blood donor ineligibility. 'While the rules were put in place to ensure a safe blood supply in the past, we know they have contributed to the stigma faced by many and hope today will be a turning point for Lifeblood and the LGBTQIA+ community and that people will feel welcome to come forward to donate their lifesaving plasma,' he said. Lifeblood chief executive Stephen Cornelissen estimates that an extra 24,000 people will donate plasma in the next year. NewsWire / John Appleyard Credit: News Corp Australia Throughout the '80s and '90s, AIDS became highly stigmatised, and high-profile media campaigns such as the infamous 'Grim Reaper' AIDS campaign had detrimental impacts on the already marginalised LGBTQIA+ community – a residual trauma that many still vividly recall. On Monday, several gay men donated their plasma at the Lifeblood clinic in Sydney – some for the first time and others for the first time since they became ineligible in their youth. For Kane Wheatley, 44, a schoolteacher from Sydney's inner west, donating plasma always seemed just out of reach. 'I spent my whole life thinking that I couldn't get married – and then I was able to get married … and so donating blood or plasma … I thought it was never going to be an option – we were just never going to get there,' Mr Wheatley said. Schoolteacher Kane Wheatley said donating blood was a 'privilege'. NewsWire / John Appleyard Credit: News Corp Australia 'Today it just feels really great to be able to get across the line. To be one of the first people to do this and help normalise it and show people that we can do this … it's really flattering. 'I feel really honoured and really special to be able to do it.' Matt Higgs, 31, said he was a regular donor in his youth, but his sexuality eventually rendered him 'ineligible' – an experience that he called 'pretty common'. 'My partner is the same, he has a scar on his arm because he used to donate so regularly,' Mr Higgs said. Mat Higgs donated blood in his youth but stopped for a long time due to the perceived risks his sexuality posed. NewsWire / John Appleyard Credit: News Corp Australia 'I was healthy, but because I was in a relationship with a man, I couldn't donate.' Mr Higgs acknowledged the history of his ineligibility but said change was well overdue. '(Preventing gay men from donating blood) was a response that was maybe warranted at the time, but we've moved so far beyond the time of where that decision was made and so it's huge (for destigmatisation) for sure,' he said. 'It's a great feeling to be able to come back and give back … I know plenty of people that have needed blood products in their life and to be able to contribute to that is really cool.' Plasma is an essential component of more than a dozen medical treatments for illnesses like chickenpox, brain disorders, tetanus, measles, liver disease and haemophilia.

‘Hidden problem': Concern over dodgy ‘botox'
A leading injectable cosmetics figure is seeing a 'scary' number of unlicensed operators pushing dangerous procedures. In 2023, Australia's legitimate injectable cosmetics industry was worth $4.1bn. Meanwhile, authorities receive about 100 complaints each year concerning non-surgical cosmetic procedures, levelled at medical practitioners, nurses, midwives, dentists, psychologists and Chinese medicine practitioners. Dr Vivek Eranki, a cosmetic medicine practitioner with national oversight, is raising the alarm after authorities seized two counterfeit batches of botulinum toxin – or botox – in recent months. 'This is more of a hidden problem, in that it is very easy for practitioners to pass it off as they are using a real product – but not documenting exactly what's been used,' Dr Eranki told NewsWire. The injection of botulinum toxin and fillers is a hugely popular and expanding industry in Australia. Credit: Supplied Dr Eranki describes the black market injectors as very discreet and crafty about what they are saying is being injected. 'People can put in false information if they are trying to cover their tracks and this is what makes it so scary,' Dr Eranki said. 'We know there are fake products coming in and it is very easy to hide it.' This week, the national medicine regulator revealed two separate batches of counterfeit botox had been seized at the border in recent months. The vials were packaged to look like a genuine brand, but typos alerted authorities. The Therapeutic Goods Administration stressed the botox was purchased from an overseas website, and the duped manufacturer confirmed the batch numbers were illegitimate. Because they are investigating further, the TGA is unwilling to say where and when the boxes were seized, nor what type of establishment had ordered them. In a statement, a spokeswoman from the Australian Medical Association said people should use only qualified health practitioners, 'The AMA reminds Australians that all medical procedures, including cosmetic injections, carry risk and should only be performed by suitably qualified health practitioners,' the spokeswoman said. 'Anyone planning a procedure should ensure they understand the skills and qualifications of the person undertaking the procedure.' Dr Eranki said common sense was the key to avoiding shady injectors. 'Never go to somebody's house, never go to a hair salon to get your treatment done. Make sure that whoever's doing your treatment is adequately trained and qualified.' 'At the end of the day the governmental infrastructure, the regulators, the authorities can only do so much. At some point, common sense needs to take over. And I think that's where the solution lies.' In January, three Sydney women ended up in hospital with botulism infections, with one requiring treatment in the intensive care unit. The Health Care Complaints Commission issued a temporary, and then permanent, prohibition order against unregistered injector Norsafiza Binti Zakaria, who advertised her services using at least six different aliases. The Australian Health Practitioner Regulation Agency has conducted multiple raids on commercial and private residences across the country in recent months, seizing illegal injectables from unqualified practitioners. The counterfeit vials were in genuine-looking packages. TGA Credit: Supplied AHPRA received 360 complaints about non-surgical cosmetic procedures between September 2022 and March 2025. These notifications were made against medical practitioners, nurses, midwives, dentists, psychologists and Chinese medicine practitioners. ''If something doesn't feel right then patients should trust their gut and hit pause,' a spokesperson said. 'Patients should ensure that their injector is a registered health practitioner by asking for their registration number and looking them up on the national register of practitioners.'
