New study shows some plant-based diets may raise heart disease riskSummary: Researchers tracking over 63,000 adults found that high-quality, minimally processed plant foods significantly reduce cardiovascular risk. But when those plant foods are ultra-processed, the advantage disappears—and can even backfire. Some ultra-processed plant diets increased risk by 40%. The study urges a shift toward whole, naturally nutrient-rich plant foods. FULL STORY Not all plant-based diets improve heart health—only those built on minimally processed, nutrient-dense foods do. Ultra-processed plant products can erase the benefits and even increase cardiovascular risk. Credit: Shutterstock Previous studies have indicated that eating large amounts of ultra-processed foods[1] is linked with a higher likelihood of developing cardiovascular diseases. Other research[2] has found that diets centered on plant-based foods can lower this risk when those foods offer balanced nutrition and are consumed in appropriate proportions. To explore how nutrition relates to cardiovascular health in more detail, scientists from INRAE, Inserm, Université Sorbonne Paris Nord, and Cnam examined more than whether foods came from plant or animal sources. Their assessment also incorporated the nutritional makeup of foods, including factors such as carbohydrate, fat, and antioxidant vitamin and mineral content, along with the level of industrial processing involved. How the Study Evaluated Diets and Food Choices The team evaluated data from 63,835 adults enrolled in the French NutriNet-Santé cohort. Participants were followed for an average of 9.1 years, with some tracked for as long as 15 years. Information on what they ate and drank (collected over at least three days) was gathered through online questionnaires. This detailed approach allowed researchers to classify diets based on the share of plant-based and animal-based foods, while also considering both nutritional quality and processing level. The findings showed that adults who consumed more plant-based foods of higher nutritional quality (lower in fat, sugar, and salt) and with minimal industrial processing had about a 40 percent lower risk of cardiovascular disease compared with those who ate fewer nutritious plant-based foods and more animal-based products[3]. However, people who ate larger amounts of plant-based foods that were nutritionally higher quality but ultra-processed, including items such as industrial whole meal breads, store-bought soups, ready-made pasta dishes, or commercially prepared salads with dressing, did not experience a reduced cardiovascular risk relative to individuals who consumed fewer of these products and more animal-based foods. Ultra-Processed Plant Foods and Increased Heart Disease Risk A notably higher risk emerged for adults whose diets were dominated by plant-based foods that were both lower in nutritional quality and ultra-processed. These items included crisps, sweetened fruit drinks or sodas made from plant extracts, chocolate-based sweets or confectionery, sugary breakfast cereals, and savory biscuits. Their cardiovascular disease risk was roughly 40 percent higher than that of people who consumed more plant-based foods of good nutritional quality with little or no industrial processing. Why Processing Level Matters for Plant-Based Eating Overall, the results show that understanding the relationship between diet and cardiovascular health requires considering the nutritional quality of foods and how heavily they are processed, in addition to the balance of plant-based and animal-based components. These findings support public health recommendations that encourage the consumption of plant-based foods that are both nutritionally high quality and minimally processed (such as fresh, frozen, or high-quality canned fruits and vegetables without added fats, salt, sugar, or additives).

Mother on carnivore diet says her children are ‘flourishing’ eating only meat and eggs
Story by Molly Powell
A mother who only eats a diet of meat, fish, eggs and full-fat dairy has encouraged her husband and two children to follow suit.
In a bid to loose weight, Olivia Khwaja, 50, a freelance strategic consultant from Ascot, initially followed the keto diet - which is high-fat, low-carb. She dropped from 95kg (14st 3lbs) to 75kg (11st 11lbs) from 2020 to 2022. That year, she discovered the carnivore diet, which required her to cut out plant-based foods entirely. This means she solely eats animal products such as steak, eggs and chicken liver pate. She has since lost an additional 20kg, dropping to 55kg (8st 9lbs).
NHS advice says consuming too much meat can increase the likelihood of people getting bowel cancer and recommends a balanced diet including fruits and vegetables – but Khwaja said her new diet has given her smoother skin and a clearer mind on top of the benefits to her waistline.

Such was her success that she has now inspired her husband Greg, 50, and their children, Eden, 16, and Bailey, 13, to follow suit, with Greg losing 39kg and their children “flourishing”. Khwaja has shared her journey with 10,000 Instagram followers, under the handle @oliviakhwaja, focusing on advice to cut out processed foods and said she has “not heard much” criticism on social media or from her children’s school.
Khwaja told PA Real Life: “After being on the carnivore diet for a few weeks, I woke up and I just felt this feeling of euphoria, like I’ve never felt so happy and so excited about life. And just looking at the sky, I was like, ‘It’s just so blue and so beautiful’. It’s like I was living under a cloud without realising and it just lifted. I’ve never pushed either of my children into this. They’re on their own journey, but I think they’re both happier avoiding addictive foods and love the freedom that comes with it.”

Khwaja wanted to make lifestyle changes to improve her health after losing her parents in 2014 and 2015. “My mum had type 2 diabetes … it made me think that I should improve my health so I don’t get the conditions when I’m older,” she said. “My dad had Alzheimer’s, which encouraged me too.” So, with the additional goal of losing weight, Khwaja followed the keto diet from 2020 to 2022, consuming high-fat and low-carb foods.
The British Heart Foundation does not recommend the diet for losing weight due to limited research into the keto diet for weight loss, but Olivia said she lost 20kg, with her BMI dropping from 38.3 to a 30.3, and felt more energised.
In 2022, she came across the carnivore diet on social media, where it was receiving “rave reviews” from followers. Initially, she was “against it” due to its exclusion of fruit and vegetables, but decided to “keep an open mind” and give it a try.

On a typical day, Khwaja now eats her first meal of locally-sourced eggs and sardines at around 4pm, but this can change depending on when she is hungry. A few hours later, she has a large ribeye steak cooked in beef tallow, often accompanied by homemade mayonnaise.
On weekends, she and her family also have homemade jerky, bacon, sausages and homemade chicken liver pate on its own, without bread. “I just buy eggs, proper butter, and meat whenever we want it and keep it in the fridge,” she said. “Whenever I get hungry, I go into the fridge and cook something. We eat everything simply … it’s a simple life.”
After just three weeks on the diet, Khwaja felt like a “new woman” and now weighs around 55kg, with a normal BMI of 22.2.
Khwaja said she can also cycle faster with a quicker recovery time, has a clearer mind, softer skin and no longer has skin tags. “I’ve never felt so good in my life – I can’t remember feeling this positive and healthy, and having so much energy, as a child or a teenager, it’s transformed my life,” she said.
Since following the carnivore diet, her husband and children have got on board, and Khwaja claims they have experienced similar benefits. She said her husband has gone from 122kg (19st 3lb) to 83kg (13st 1lb) and also feels more energised. She said: “I thought, we spend so much money buying vegetables and time cutting them, chopping them, steaming them, putting them on a plate, and then most of the time we put them back in the fridge, because my children don’t finish them and they don’t like them, I’m just not going to bother anymore. And we stopped doing that, and that saved a ton of money. They saw mine and my husband’s steak, so wanted to try going carnivore too. But my son does still eat fruit sometimes.”

Since switching diets, Khwaja said she feels her children are “flourishing”. She claimed their skin has cleared and her daughter is excelling in sports and athletics. Occasionally, her children have “fallen off the wagon” and eaten chocolate, but Khwaja said they quickly notice how “bad they feel” afterwards.
To people who would argue Khwaja is damaging her children’s health by not giving them fruit and vegetables, she said: “It would be worthwhile they do some research, because all the nutrients they need are available in abundance in meat and much more so than in vegetables.”
She shares her health journey on Instagram under the handle @oliviakhwaja, and Khwaja claims she has not received criticism by her 10,000 followers or her children’s school. “I coach families who want to help their kids transition away from processed foods, but I never tell anyone to stop their children from eating vegetables,” she said. “That’s just a personal choice for our family. I’m sure plenty of people disagree, but I haven’t heard much from them.”
To people who are sceptical about the carnivore diet, and have concerns it may cause cancer, she said: “I totally understand their concerns – I was at least sceptical. But my main learning from this whole journey has been that what we think we know about any diet isn’t in any way concluded. In my case, it worked for me and I saw the benefits quickly.”
The NHS recommends you speak to your GP about losing weight safely by eating a healthy, balanced diet and regular physical activity.
