Binging on French fries thrice a week may raise diabetes risk by 20%: Study
The study, which tracked the diets of more than 205,000 adults over decades, however, showed that other forms of potatoes -- including baked, boiled, and mashed — do not increase the risk of diabetes.
The study, published in the BMJ, also found that swapping any form of potato for whole grains may lower the risk of diabetes.
'The public health message here is simple and powerful: small changes in our daily diet can have an important impact on the risk of type 2 diabetes,' said corresponding author Walter Willett, professor of epidemiology and nutrition at Harvard T.H. Chan School of Public Health.
'Limiting potatoes -- especially limiting French fries -- and choosing healthy, whole-grain sources of carbohydrate could help lower the risk of type 2 diabetes across the population,' Willett added.
The new study examined the diets and diabetes outcomes of 205,107 men and women.
For more than 30 years, participants regularly responded to dietary questionnaires, detailing the frequency with which they consumed certain foods, including French fries; baked, boiled, or mashed potatoes; and whole grains.
Throughout the study period, 22,299 participants reported that they developed diabetes.
The researchers calculated, however, that eating whole grains – such as whole grain farro – in place of baked, boiled, or mashed potatoes could reduce the risk of diabetes by 4 per cent.
Replacing French fries with whole grains could bring diabetes risk down by 19 per cent. Even swapping refined grains for French fries was estimated to lower diabetes risk.
On the other hand, soft drinks, ketchup, jams, tinned fruits and potato chips — all these taste delicious and are convenient, but it is important to note that they are examples of processed foods and large quantities may be harmful to your health.
According to UK's NHS, processed food is any food that has been altered in some way during preparation. Food processing can be as basic as freezing, canning, baking, and drying.
'Processed food is not 'real food,' it is food that has been modified by chemical processes and contains additives, flavorings, emulsifiers and stabilizers.
The food is then assembled into ready-to-eat hyper palatable food called 'Cosmetic food'.
The easiest way to judge how processed the food is to look at the length of the food label at the back of the packet. The longer the list, the more processed is the food in it,' Dr Tejal Lathia, Consultant Endocrinologist, Hiranandani Hospital, Vashi- A Fortis Network Hospital, told reporters. Natural sugars are found in fruit, cereals and vegetables along with fiber, vitamins, minerals and antioxidants and thus, they are healthy. Refined or processed sugar, however, lacks these accompanying vital nutrients and is found in most processed foods, even those that are not considered sweet like ready-to-eat soups and ketchup.
Notably, processed food includes packaged breads, breakfast cereals, confectionery (sweets), biscuits, pastries, buns, cakes, industrial chips and French fries, soft and fruit drinks or packed juices, packaged pre-prepared meals (frozen meals) and reconstituted meat products. As per the doctor, processed foods are harmful because they contain higher amounts of unhealthy fat, sugar and salt.
The extra calories - termed 'empty' calories because they lack nutritional value - consumed in the form of fat and sugar, from processed food, leads to weight gain and high blood sugar. Excess sodium, that comes from salt, in this type of food raises blood pressure and causes water retention.
The combination of high blood sugar and blood pressure with obesity increases the risk of heart diseases and cancer. Furthermore, most processed foods also lack fiber and protein, which are necessary for satiety or the feeling of being full after a meal. Failure to feel full results in consumption of large quantities of the processed food at one time.
Lastly, these processed foods contain little to no vitamins and minerals. If a large part of a person's diet consists of processed foods, they can suffer from lack of important vitamins and minerals.
'A study from Brazil showed that preschool children who consumed excess ultra processed food (40 per cent of their daily calorie intake) had increased waist circumference by the time they entered primary school.
Two large European studies have studied the link between consumption of processed foods and health.
One study found that people who consumed even 10 percent more processed food, had increased risk of heart attacks and strokes.
'The second study showed that those who consumed 4 or more servings of processed food a day had a 60 percent increased chance of dying, when compared with those who consumed less than 2 servings of processed food per day,' Dr Tejal told reporters.

The Royal Marsden Cancer Charity hails Sheikha Jawaher Al Qasimi's role in advancing precision medicine for cancer treatment
A humanitarian initiative by HH Sheikha Jawaher Al Qasimi, the lab was established with a £500,000 donation One of only two UK labs selected by NHS England to evaluate long-read whole genome sequencing for clinical application. Enhancing lung cancer genetic mutation analysis using 'Liquid Biopsy' technology Capacity has been doubled to deliver an additional ,000 genetic tests monthly Actively participating in clinical trials for DNA-based personalised therapies The Royal Marsden is a specialist cancer centre that brings together world class researchers and dedicated clinical teams providing expert compassionate care Sharjah: The Royal Marsden Cancer Charity; which supports the work of The Royal Marsden; has commended the significant support of Her Highness Sheikha Jawaher bint Mohammed Al Qasimi, Wife of the Ruler of Sharjah and Founder/Royal Patron of the Friends of Cancer Patients (FoCP). Its annual report highlighted her contributions to advancing cancer research, particularly through initiatives over the past five years that have accelerated progress at the Sharjah Clinical Genomics Laboratory within the National Institute for Health and Care Research (NIHR) Centre for Molecular Pathology (CMP); housed within The Royal Marsden in the UK. These efforts have greatly enhanced faster delivery of precise diagnoses and cutting-edge personalised treatments for patients. The report underscored that Her Highness's support has empowered the lab's scientific team to fast-track diagnostics and treatments, bringing hope to thousands of patients. This was achieved through the introduction of state-of-the art facilities to the Sharjah Clinical Genomics Laboratory; including the UK's first robotic genome testing facility; and bringing together world experts in molecular pathology, bioinformatics, translational research. A humanitarian grant has been driving rapid progress The Sharjah Laboratory was launched in 2018 as a humanitarian initiative by Her Highness Sheikha Jawaher Al Qasimi, who donated £500,000 to support its establishment within the CMP at The Royal Marsden in the UK. This donation reflects Her Highness's strong belief that investing in scientific research is foundational in the fight against cancer and that such research can make a genuine global impact, benefiting patients far beyond the institution itself. Founded in 1851, The Royal Marsden in London is the world's first and most renowned cancer centers. It specialises in the diagnosis, treatment, and research of all types of cancer, with a highly experienced medical team and a dedicated department for paediatric and adolescent care. The hospital serves more than 50,000 patients annually and works in close collaboration with its academic partner, The Institute of Cancer Research, London, cementing its position as a global leader in cancer treatment innovation. Recent advancements enhancing cancer care Recent advancements at the CMP are enhancing cancer care and were reflected in a comprehensive report. The 'Marsden360' service, developed in partnership with Guardant Health, uses liquid biopsy (a blood test for cancer) to identify the genetic changes in DNA, allowing patients to be matched to targeted treatments. The testing was offered as part of an NHS England national study for patients with suspected late-stage lung cancer, as well as providing a commissioned NHS ctDNA service to guide treatment decisions for eligible patients with suspected late-stage breast cancer. The report also noted the Sharjah Clinical Genomics Laboratory is on track to become the first facility in the UK to offer fully automated genomic testing, with the capacity to conduct 5000 tests monthly. This is being achieved through collaboration with Automata, a global biotech company providing robotic automation solutions to the life sciences industry. The advancement has improved early detection of genetic mutations and enabled proactive care for high-risk cancer patients. Cutting-edge technology includes the Nanopore PromethION device for precise long-read DNA sequencing, already analyzing 110 whole genomes to yield new insights for treatment development. The CMP also plays a vital role in key clinical trials like 'ENABLE-NGS', 'PREVAIL', and 'ICED' (targeting leukemia, lung, and rare cancers), 'SIGNIFIED' (offering annual scans for Li-Fraumeni Syndrome), 'INOVATE' (blood-based monitoring for head/neck cancers), and 'RECUT Plus' (studying radiotherapy resistance). Further amplifying its impact, the lab contributed to over 24 peer-reviewed studies in 2024, presented at major conferences like ESMO and ASCO, exploring molecular profiling to redefine cancer risk and reshape treatment strategies. A UAE humanitarian vision for the world The Sharjah Clinical Genomics Laboratory reflects the UAE's vision of investing in human potential and scientific research, transforming humanitarian efforts into tangible impact in patients' lives. It serves as a prime example of successful collaboration between philanthropy and science, through which Sharjah has become an active partner and contributor to the future of genomic medicine worldwide. The laboratory's success in the UK exemplified the vision and commitment of Her Highness Sheikha Jawaher Al Qasimi commitment to supporting cancer patients. Her Highness's efforts have directly supported several specialised institutions such as Children's Cancer Hospital Egypt 57357, the Children's Cancer Center of Lebanon (CCCL), the National Cancer Institute in Egypt (Sheikha Jawaher Al Qasimi Building), and the Union for International Cancer Control's (UICC) Fund for Childhood Cancer Patients. Through these efforts, Her Highness Sheikha Jawaher Al Qasimi champions a UAE global humanitarian mission that transcends borders.

Binging on French fries thrice a week may raise diabetes risk by 20%: Study
Love to eat potatoes? Consume the starchy vegetable baked or boiled, but not as French fries, according to a study which showed that eating the popular snack item thrice a week may increase the risk of diabetes by 20 per cent.

Opinion: Is Britain finally realising that Palestinian children are human?
After nearly two years of genocide, the UK government is gearing up to accept a contingent of critically ill and injured children from Gaza. But much more is needed, says Dr Omar Abdel-Mannan am a British Egyptian paediatrician who has worked in the National Health Service (NHS) for more than 15 years. During annual trips to Gaza, I have worked alongside local doctors and witnessed first-hand the impact of Israel's blockade and bombardment on children's health. I know what it means to see children die of preventable causes. But never in my life have I witnessed this level of calculated cruelty, nor such cold complicity from those who claim to care about international law and children's rights. On 30 July, I flew with a 15-year-old Palestinian boy from Gaza named Majd Alshagnobi, his mother and two siblings from Cairo to London for specialist treatment at the Great Ormond Street children's hospital. Two of his other siblings and their father remain trapped in northern Gaza. I joined the flight as a friend and supporter of Project Pure Hope, working alongside Kinder Relief, both of which played a vital role in arranging Majd's care in Egypt and helping secure his transfer to the UK. Their work is a testament to what small networks of determined people can achieve when governments fail to act. Majd's mandible had been shattered by a bomb blast. An obvious scar across his neck marks the site of a tracheostomy performed in a hospital in Gaza under siege. His survival is a testament not just to urgent evacuation, but to the relentless efforts of Gaza's doctors and his family, who fought to keep him alive under impossible conditions. It should never take a teenager with a broken face and a scarred airway to remind Britain that Palestinian children are human beings. But that is where we are.
