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).

Harvard Has Been Anti-Meat for 30+ Years—Why?
Red meat is bad for health. We hear this from virtually all our nutrition authorities, and so, it must be true. Far less well known is the fact that this fear of eating red meat can mainly be traced back to a single person, Harvard’s Walter C. Willett, the first and most prominent anti-meat champion in academia. Indeed, in 1990, the year before he started his 25-year reign (1991-2017) as head of the highly influential Harvard T.H. Chan School of Public Health (HSPH), Willett said it’s “quite possible” that “no red meat” was the optimal amount to eat.1 His more recent work has involved leading an international effort for a near-meatless diet for all people, globally. Yet this passion has never had a foundation in solid evidence. Rather, it has been based in a mixture of personal ambition, bad science, financial interests and bias.
Willett’s unswerving advocacy for vegetarianism helps provide some context for his latest paper (paywalled), claiming that red and processed meat are “strongly associated” with an increased risk of type 2 diabetes. As the accompanying Harvard press release explained, “participants who ate the most red meat had a 62% higher risk of developing type 2 diabetes compared to those who ate the least.” The findings spurred at least a hundred headlines worldwide, including this one in The NY Times and another in the Washington Post (syndicated from Bloomberg): “Drop that Hot Dog if You Value Your Health.”
Scary news indeed for the more than half of American adults estimated to have pre-diabetes or diabetes in 2012 (today’s number is no doubt higher), and this news will surely give many people pause about choosing steak instead of something from “plant protein sources,” which the Harvard researchers say are not only healthier but also better for the planet. “Swapping red meat for healthy plant protein sources would help reduce greenhouse gas emissions and climate change, and provide other environmental benefits,” they assert. The climate change implications are serious, and we should not dismiss them, yet we’re concerned here about human health—and so will stick to that.
The errors of science in the Harvard paper are both superficial and profound. However, the bigger question is: why do Willett and HSPH put out such a constant stream of findings against animal foods when nutritionists for generations have argued, with good reason, that these foods are vitally important, if not essential to human life? Meat contains all of the essential amino acids, in the ratios that are ideal for humans. They are rich in twelve of the thirteen essential vitamins. Meat, especially, is an excellent source of vitamins A, E and all the B vitamins. Vitamins D and B12 are found only in animal products (although we might be able to get sufficient vitamin D with enough outdoor exposure to the sun). Thus, whatever we might think about eating animal foods, they are, due to their essential nutrient and ideal protein content, almost certainly crucial for the proper development and functioning of all human beings. Arguing against these foods is like taking the nutrition out of nutrition studies.
What’s certain is that for 30 years, Willett has been a fervent champion of a vegetarian diet. His advocacy is run through with ideological beliefs, some linked to an actual vegan-promoting church, and it’s hard to imagine that these factors do not interfere with the pure pursuit of science. Complicating this mix are undeniable financial conflicts of interest, including multiple six-figure donations by the food industry to HSPH during Willett’s leadership. These commercial interests converge and dovetail with Willett’s personal zeal for vegetarianism; where one starts and the other ends is difficult to know.
Indeed, Willett’s career can be seen as a case study in how a person’s beliefs can lead them into a web of financial, corporate and even ideological interests aligned with those beliefs. Over the course of a 30-year career, these fuse together into a single piece, a set of golden handcuffs for the mind. Evidence to the contrary might exist, but the researcher either ignores it or finds a way to dismiss it as insignificant.
