A plant-based diet is good for your health. But there’s one exception

It's yet another rubbishy diet study. They anaysed their data using extreme quartiles, which means that they threw away half of their data before testing it, which in turn usually means that there were NO correlations in the full dataset. And even then they got only marginal hazard ratios. For instance:"After adjustment for potential confounders, a 10% increase in the contribution of plant-sourced non-UPF in diet was associated with a 7% reduced risk of incident CVD (adjusted HR 0.93; 95% CI 0.91–0.95) and a 8% reduced risk of incident coronary heart disease (adjusted HR 0.92; 95% CI 0.90–0.94)"
Relationships as weak as that are often not replicable so the study is most safely seen as failing to show that diet has any certain effect on health at all. In plain speech, eat what you like. The best thing to do for your health is probably to have friends
Eating a plant-based diet is good for your health, but not if those plant foods are ultra-processed, a new study has found.
The findings show that all plant-based diets aren’t the same, and that plant foods can have very different effects on your health depending on what manufacturers do to them before they reach your plate.
The new research, published on Monday in the journal, Lancet Regional Health-Europe, found eating plant-derived foods that are ultra-processed – such as meat substitutes, fruit drinks and pastries – increases the risk of heart attacks and stroke. But when plant foods such as fruits, vegetables, whole grains and nuts are only minimally processed – meaning they are cleaned, cut or squeezed before packaging but served largely as they are found in nature – they have a protective effect against cardiovascular disease. The study treated freshly squeezed fruit juices as unprocessed.
Ultra-processed foods have faced intense scrutiny from health authorities in recent years. What’s unusual about the new study is that it zeroed in on the health effects of ultra-processed foods that begin as plants, comparing them with minimally processed plant foods. Given that plant-based foods are generally healthy in their natural state, the research suggests that there’s something uniquely damaging about ultra-processing that changes a food in a way that can harm a person’s health long term.
“The artificial and heightened flavours of these foods can lead people to become addicted to these flavours, making it difficult for them to appreciate the natural flavours of real foods such as fruits and vegetables,” says Fernanda Rauber, the lead author of the new study and a researcher at the Centre for Epidemiological Research in Nutrition and Health at the University of São Paulo in Brazil.
The new study analysed data on 118,000 adults who were followed for roughly a decade as part of the UK Biobank, a study that has been tracking the health and lifestyle habits of people throughout the United Kingdom. As part of the long-running study, the participants answered questions about their diets, habits and environments on different occasions and provided biological samples, and health and medical records. The findings included:
The more ultra-processed foods people consumed, the higher their likelihood of dying of heart disease.
Every 10 per cent increase in kilojoules from plant-derived ultra-processed foods was associated with a 5 per cent higher likelihood of developing cardiovascular disease and a 6 per cent higher risk of coronary heart disease in particular.
For every 10 per cent increase in the consumption of whole plant-based foods — those that were not ultra-processed — the participants had an 8 per cent reduction in their likelihood of developing coronary heart disease and a 20 per cent reduction in their risk of dying of it. They also had a 13 per cent lower risk of dying of any cardiovascular diseases.
Many of the foods studied were not foods people would typically consider a plant food. But the main ingredients in many junk foods come from plants, such as cane and beet sugars, wheat flour, corn, potatoes, fruit juices and vegetable oils.
