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).

I became a big boy once I hit drinking age in the mid-late 90's, and it was around that time that my next door neighbor gave me a book to read, called Dr. Atkins New Diet Revolution. I read it from cover to cover in almost no time at all, because it was both easy to understand, and it the science made sense. I applied what I learned and lost weight with ease. If I recall correctly, I went from the low 200's down to just under 165, and for the first time in my life truly felt "skinny". I was a believer in low carb ever since. Unfortunately, I didn't stay on the fourth phase, "Atkins For Life", but instead became a yo-yo dieter in the years and decades since. I have been routinely swinging back and forth between 180 and 230 like a pendulum. Then as I've gotten older, I'd make it down to 190, then 195, then 200, the 205, and started to think my metabolism was slowing down with age.
Now I am in my upper 40's and over the years have developed some chronic conditions that have forced me to give more serious thought to my weight and what I put in my mouth. During the pandemic, I actually lost a lot of weight and could make the connection that it was because I was cooking good food at home because for a time we couldn't go to restaurants and being in crowds was discouraged. My blood labs were improving too. But in 2022 I backslid again and gained it all back, and the blood labs reflected that this was not good. So, I started low carb again in March. But today's "low carb" diets have been tainted by manufacturers who make all these processed "keto" foods, and make up low "net carb" counts using mathematical trickery. I wasn't having much success. Then in late March and ealy April I started learning about True Keto, and decided to go from the "dirty keto" I had been doing to REAL whole food Keto and vowed to never eat sugarcane or grains again. After 6 weeks of just meat and vegetables I was losing weight and feeling fantastic.
In the middle of May I broke my ankle, and knew I was going to be sedentary for the next couple months. Prior to this, I had been learning about Carnivore and intermittent fasting, so on that day I decided to go fully zero carb, carnivore and practice intermittent fasting 16-8. I would eat and noon and again no later than 8pm. During those 2 months where I could not bear any weight on my leg, I lost 10 more pounds.
My blood work is showing improvement too. I've reversed a few conditions, such as high blood pressure and ulcerative colitis, and am working on a couple others. Most of all, I feel fantastic. I'm truly believe I am a committed 97% carnivore, occasional ketovore. I'm trying hard to make sure the only thing that goes in my mouth now comes from the Creator above, from farm to fork, from the field to the table, with very few exceptions. My only regret is that I had learned a lot about this with that book in the 90's but didn't stick with it.
