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).

Retired military-type here. I had always managed reasonable fitness, at least enough to not get into trouble, but my weight and general broken-ness seemed to increase with age and I just assumed this was the natural course of things. I'm 5'10" and was hovering at around 200 lbs when I started a keto-like diet and changed my workouts while on a deployment. It worked, I dropped 20 lbs and was able to mostly maintain for the rest of my career. This "maintenance" still incorporated a lot of plants, as well as a no-holds cheat day once a week or so.
After retirement, I suppose I slacked off a bit and the weight started creeping up again, joint pains increased, and, in retrospect, my mental health was probably not ideal. I was starting to get desperate a little over a year ago and tried some fasting. I did one week with water only, and it had amazing results as far as my mental clarity and general mood, and it made the transition to eating only one meal a day really easy which also helped me maintain. I still had problems though, I'd damage something (shoulders are bad, occasional muscle strain, etc) every couple of months while working out, and by the end of last year, my knees were getting so bad that I felt like it was time to start that medical spiral of surgeries and eventual replacement.
I abruptly decided to switch to meat only around the middle of January, no doubt subtly influenced by various youtube videos or other social media, but with some apprehension as well, as there are just as many videos out there telling me I'm straight up murdering myself by doing this. I told myself I would try it for 2 weeks, just to see how I felt. I was a week into it when I picked up Dr. Shawn Baker's book and that helped allay some of my concerns.
So here I am, end of February and still sticking with it. It's freaking magical; had I found a drug that has this kind of general effect on everything from my mood to my various aches and pains, I would be a junky. My insomnia is fixed, I'm starting to work out again and don't feel like I'm going to break something. People who I see fairly infrequently ask why I look different. I'm not anxious or angry. Really, my only problem is that I feel like I may appear crazy; I want to tell everyone that I've found something supernatural and I know how that would look. So instead of shouting from the rooftops, I'll post here for now. Nice to meet you all!
