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 last six months I have tried to eat to hit a protein target. Still strict carnivore (18-19 months) but eating pretty much more than I want each day to have enough protein for muscle growth. The proteins went up, and I didn't hit the fat targets, so I had some stiff and hard stools. I increased the fat to catch up to the proteins and help with the stools as well. In turn, so my diet has not been 'eat when hungry-eat til full' for the last six months or so.
After six to 12 months on carnivore my cholesterol dropped a few points but took a significant bounce up at the 18-month mark. I was expecting an increase with the sheer amount of food I was eating but I didn't expect the numbers to jump this much.
May thru November 2024 May 2025 November 2025
Total Cholesterol 239 212 274
LDL 185 150 164
HDL 37 39 55
Tri-G 49 43 41
My total weight loss of carnivore has been 95-96lbs and in the last couple months I gained 12-15 pounds bouncing around the 215-mark for the most part. The weight gain I expected as the lifting has become more and more a part of my day to day. I am stronger now than I can even remember (never was much on lifting) and the energy levels are still that constant/ability to keep going since early on with carnivore. I feel just as good now as I did six months ago. I had a great visit with my neurologist yesterday. (He is moving back home to Alabama so I quipped that carnivore was going to run him out of business. He replied, "I hope so".) He told me of all his NMO patients I have made the biggest turnaround and went from ho-hum numbers 18 months ago til now. All my markers are within limit is with the exception of one. I started carnivore 18 months ago, so I let people draw their own conclusions. (LOL, preaching to the choir in a forum such as this). My blood sugar crept up a little. My day-to-day over the last six months moved from the low 80's to touching the low 90's every now and then. Yesterday it was 94. Blood pressure was 100/58 before the infusion and 98/54 afterwards (laying in a recliner for five hours).
Even with the cholesterol making a jump this is how I judge my health. When I first started the infusions I was 310+lbs and was on a dumpster diet. After each infusion I would be wiped completely out. The 45-minute ride home felt like hours. I hit the recliner for a stretch then to bed really early. restless sleep all night and pretty much flat the next day. Fast forward from 18 months ago, yesterday I saw the Neurologist at 8AM, started the infusion at 9AM (use to be six hours at 310 pounds but now 5 hours at 220) and I was home by 3PM. The ride home was a simple ride home and I ate bacon, sausage and eggs mid-afternoon. I went outside and busted/split just about a Toyota truck full of red oak from two trees we had taken down last week. Fed all the animals as it got dark and back in the house. I went to bed at 9 and now I am up at my normal 3AM time frame. I checked out the forum and now off to the gym to be one of those 4AM weirdos (LOL).
I'm going to call that progress, maybe with a chunk more of fat running free in my bloodstream, but over the last 18 months, progress the same.
I don't think we make progress over months/years without stacking up a bunch of day-to-day wins.
Hope all is well with you and yours.
