Your ‘five-a-day' can now include chocolate and red wine, study finds
A new five-a-day diet including tea, apples, oranges and berries − all foods rich in chemicals called flavonoids – will help people to live longer, a study has found.
Flavonoids have a range of benefits, including lowering high blood pressure. Scientists have long known them to be good for health, but the new study is the first to investigate the benefits of a diversity of different flavonoids, not just the quantity.
There are five main groups of flavonoids covering dozens of unique chemicals, but one main tranche is anthocyanins, found in abundance in grapes and red wine.
Tea is rich in flavan-3-ols, another flavonoid, while orange juice is full of flavonones, and kale has high levels of flavones.
Some foods, such as apples and tea, contain several flavonoids of different categories.
Scientists looked at the benefits of a diversity of these chemicals in a person's diet by assessing almost 125,000 Britons enrolled in the UK Biobank. Specific food and drink intake was compared to health outcomes over a decade of follow-up by scientists at Queen's University Belfast.
Participants who consumed at least 1,000 milligrams of flavonoids a day were a fifth less likely to die during the study period, data showed, confirming that flavonoid quantity was linked to better health.
Further analysis on the impact of flavonoid diversity found people in the lowest 20pc of the study consumed on average just one food product which was rich in flavonoids a day.
Those in the top 20pc who ate five portions of flavonoid-rich foods a day were found to have a 16pc lower risk of death during the study period.

Tea and dark chocolate could help you live longer, Queens study shows
Tea, berries and dark chocolate could lead to a longer life span, new research has indicated. The study found those who consume a diverse range of foods rich in flavonoids, such as tea, berries, dark chocolate, and apples, could lower their risk of developing serious health conditions and have the potential to live longer. The study was led by a team of researchers from Queen's University Belfast, Edith Cowan University Perth, and the Medical University of Vienna and Universitat Wien. The findings reveal increasing the diversity of flavonoids within your diet could help prevent the development of health conditions such as type 2 diabetes, cardiovascular disease, cancer and neurological disease. Flavonoids are found in plant foods like tea, blueberries, strawberries, oranges, apples, grapes, and even red wine and dark chocolate. Published on Tuesday in Nature Food, the research tracked more than 120,000 participants aged from 40 to 70 years old for over a decade. It is the first study of its kind to suggest there is a benefit to consuming a wide range of flavonoids beyond that of simply consuming a high quantity. Study co-lead, Professor Aedín Cassidy from the Co-Centre for Sustainable Food Systems and Institute for Global Food Security at Queen's said: 'We have known for some time that higher intakes of dietary flavonoids, powerful bioactives naturally present in many foods and drinks, can reduce the risk of developing heart disease, type 2 diabetes, and neurological conditions like Parkinson's. 'We also know from lab data and clinical studies that different flavonoids work in different ways, some improve blood pressure, others help with cholesterol levels and decrease inflammation. This study is significant as the results indicate that consuming a higher quantity and wider diversity has the potential to lead to a greater reduction in ill health than just a single source.' Edith Cowan University research fellow, first author and co-lead of the study, Dr Benjamin Parmenter, made the initial discovery that a flavonoid-diverse diet is good for health. He explained: 'Flavonoid intakes of around 500mg a day was associated with a 16% lower risk of all-cause mortality, as well as a 10% lower risk of CVD [cardiovascular disease], type 2 diabetes, and respiratory disease. That's roughly the amount of flavonoids that you would consume in two cups of tea. 'However, those who consumed the widest diversity of flavonoids, had an even lower risk of these diseases, even when consuming the same total amount.'

Exercise slashes risk of death in patients with colon cancer
Exercise slashes the risk of death in patients with colon cancer by more than a third, a trial has found. Physical activity could also prevent the disease from coming back, as well as lifting mood, reducing fatigue and boosting strength, according to researchers. Colon cancer develops in the part of the large intestine known as the colon, part of the large bowel, which also comprises the rectum and anus. It can sometimes be referred to as bowel cancer or colorectal cancer. Our study gives clear, encouraging evidence that physical activity can reduce the risk of cancer returning for some people with colon cancer The CO21 Challenge trial, led by researchers in Northern Ireland and Canada, involved 889 people with colon cancer from six countries. All patients had had surgery and chemotherapy for their cancer and were deemed well enough to exercise, but were not meeting recommended physical activity levels. Around half were given a three-year tailored exercise programme, which included the likes of brisk walking, circuit classes, cycling, or swimming. The plan included in-person coaching sessions for the first six months, as well as regular meetings with a physical activity consultant. We now need to work with policymakers and healthcare providers to embed exercise into treatment plans where appropriate The other group were offered materials that promoted exercise and nutrition. The study found that after five years, the risk of dying, relapse or developing a new cancer was 28% lower in the group with a tailored exercise plan. After eight years, patients in the physical activity group had a 37% lower risk of death. Professor Vicky Coyle, UK lead researcher for the trial and clinical professor at Queen's University Belfast, said: 'During the trial, we supported people to reach their weekly exercise target in a way that worked for them. 'This could be a brisk walk for around 40 minutes every day, but some patients were also doing circuit classes, cycling, swimming, and many other activities. We know that physical activity regulates several key biological processes that could explain these results, and further research will help us uncover why exercise is having such a positive impact 'Our study gives clear, encouraging evidence that physical activity can reduce the risk of cancer returning for some people with colon cancer. 'We now need to work with policymakers and healthcare providers to embed exercise into treatment plans where appropriate.' Dr Joe Henson, associate professor in lifestyle medicine at the University of Leicester, said: 'Leading the exercise sessions in Leicester, I saw first-hand that this reduced fatigue, lifted people's mood, and boosted their physical strength. 'We know that physical activity regulates several key biological processes that could explain these results, and further research will help us uncover why exercise is having such a positive impact.' The findings, published in the New England Journal of Medicine and presented at the American Society of Clinical Oncology (ASCO), could 'transform clinical practice', according to experts. This trial has the potential to transform clinical practice, but only if health services have the necessary funding and staff to make it a reality for patients Caroline Geraghty, senior specialist information nurse at Cancer Research UK, said: 'Being active has many benefits, and this study shows that exercise doesn't only improve well-being – it can also boost people's chances of surviving colon cancer. 'Everyone recovering from cancer should have access to tailored support to help them live longer, better lives. 'This trial has the potential to transform clinical practice, but only if health services have the necessary funding and staff to make it a reality for patients. 'It's important to remember that every cancer journey is different – starting new activities after treatment can feel overwhelming, and it may not be the right option for everyone. Take things at your own pace and speak to your doctor to discuss what is safe for you.' Professor Peter Johnson, NHS national clinical director for cancer, said: 'These exciting findings add to the growing evidence of the benefits of physical activity for people affected by cancer, not just in helping them be fitter for treatment and boosting their immediate recovery, but reducing the risk of the disease coming back. 'This is why we've asked cancer alliances across the country to look at ways to encourage and support patients to do physical activity and ensure every healthcare professional they see can help them be in the best possible place – both physically and mentally – before, during and after treatment.'
