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).

The Very Meaty History of Treating Diabetes Before Insulin
A surprisingly effective method for its time
It’s been just over a century since insulin was first used to treat diabetes. Given that doctors and scientists have known about diabetes for thousands of years — and have been searching for the best way to improve the lives of people with the condition since then — that means a lot of different treatments were tried out over the years all over the world. And, as it turns out, some of them involved plenty of meat.
In an excerpt from his book Rethinking Diabetes: What Science Reveals about Diet, Insulin, and Successful Treatments, Gary Taubes recounts the story of the 18th century doctor John Rollo, who “may have been the first physician to successfully bring a case of diabetes under control.” What did Rollo prescribe his patients? Meat. So, so much meat.
Taubes refers to this as “the animal diet,” which is exactly what it sounds like. (Thankfully, Rollo’s refinement of this meant that he moved away from telling patients to eat “rancid old meat and fat.”) The thinking behind this was to reduce carbohydrates in diabetes patients, and it seems to have worked to prolong the lives of several of the people he treated, provided they stuck to the regimen.
If you’re reading this description and getting flashbacks to, say, the heyday of the Atkins Diet, you’re not alone. And while it’s nowhere near as sophisticated as insulin, Rollo’s overall line of thinking has aged relatively well. In 2018, Anahad O’Connor wrote in the New York Times about a study that showed diabetes patients successfully regulating their blood sugar levels via a diet low in carbohydrates and high in protein.
There’s another lesson in Tabes’s retelling of Rollo’s story, and it stems from the experience Rollo and his colleagues had in treating diabetes with the “animal diet.” Not surprisingly, Rollo and his fellow doctors learned that patients fared far worse when they cheated on their diet, snacking on bread or something similar before it was safe to do so. It doesn’t matter if it’s the 18th century or the 21st — sticking to what a doctor prescribes can make a big difference in treating whatever ails you.
