Plant-Based Diets and Cardiovascular Health: New Study Explores the Link
A recent study conducted by a research team from INRAE, Inserm, Université Sorbonne Paris Nord, and Cnam delved into the relationship between nutrition and cardiovascular health. The researchers went beyond the traditional distinction between plant-based and animal-based foods to consider the nutritional quality and degree of food processing as well.
The study analyzed health data from 63,835 adults participating in the French NutriNet-Santé cohort over an average follow-up period of 9.1 years. By collecting detailed dietary intake information through online questionnaires, the researchers were able to categorize diets based on the proportion of plant-based to animal-based products and the level of industrial processing.
Published in The Lancet Regional Health—Europe journal, the study revealed some interesting findings. Adults who consumed diets rich in plant-based products of high nutritional quality, with minimal processing, had a significantly lower risk of cardiovascular disease compared to those with diets lower in such products and higher in animal-based foods.
Interestingly, adults who consumed plant-based products of high nutritional quality but that were ultra-processed did not experience the same cardiovascular benefits. Foods like industrial wholemeal breads, ready-made pasta dishes, and commercially prepared salads fell into this category.
On the other hand, adults who consumed a large proportion of plant-based products of lower nutritional quality and that were ultra-processed had a 40% higher risk of cardiovascular disease. This category included snacks like crisps, sugary drinks, chocolates, and savory biscuits.
These results underscore the importance of considering both the nutritional quality and processing level of foods, in addition to the plant-to-animal balance in the diet. The study suggests that promoting plant-based foods of good nutritional quality, with minimal processing, could be beneficial for cardiovascular health.
In conclusion, the study highlights the significance of making informed dietary choices to reduce the risk of cardiovascular diseases. By focusing on plant-based foods that are nutritionally balanced and minimally processed, individuals can potentially improve their heart health. This research provides valuable insights for public health and nutrition policies aimed at promoting healthier eating habits.
