The following is an excerpt from Medscape.
Following a diet rich in healthy plant-based products may lower one's risk of breast cancer, but not if that diet happens to be high in unhealthy foods, researchers have found.
The study of more than 65,000 people showed that plant-based diets that were high in whole grains, fruits, and vegetables appear to be more protective against breast cancer than diets rich in processed plant-based products, such as juice and chips.
"Results suggest that the best plant-based diet for breast cancer prevention could be a healthy plant-based diet comprising fruit, vegetables, whole grains, nuts, and legumes," said Sanam Shah, MBBS, FCPS, MPH, a doctoral candidate in epidemiology at Paris-Saclay University, France, who is the lead author of the new study. "In contrast, an unhealthy plant-based diet comprising higher intakes of primarily processed products of plant origin, such as refined grains, fruit juices, sweets, desserts, and potatoes, would be worse for breast cancer prevention."
Shah's group will be presenting their research online at NUTRITION 2022, the annual meeting of the American Society for Nutrition.
Although the role of plant-based diets in cancer prevention has received extensive attention, Shah said few studies have assessed the influence of the quality of those diets on the risk of breast cancer.
Shah and colleagues conducted a prospective cohort study to investigate the link between healthy and unhealthy plant-based diets and breast cancer risk. Unlike other studies, the researchers also evaluated the effect of a gradual decrease in animal products in diets on health.
Shah's group followed 65,574 postmenopausal women in France (mean age, 52.8 years) from 1993 to 2014. The researchers used self-reported food questionnaires to classify women into groups on the basis of adherence to a mostly plant or animal diet. Plant-based diets did not exclude meat but had more plant than animal products, Shah said. The researchers also grouped women on the basis of how healthy the plant-based diets were.
Over the 21-year study period, 3968 women were diagnosed with breast cancer. Those who adhered to a more healthful plant-based diet had a 14% lower risk than average of developing breast cancer, while those who adhered to a less healthful plant-based diet had a 20% greater risk of developing the disease.
Nutritional quality varies greatly across plant-based foods. Quality plant-based diets should focus on variety to avoid nutritional deficiencies in iron, zinc, calcium, and vitamin B12, Shah said.
Ridiculous article of a biased study. It doesn't take a rocket scientist to observe this article states that a plant-based diet of fruits, vegetables, & grains is healthier than a plant-based diet of junk foods. In fact, ANY diet that eliminates processed sugar and junk foods whether plant-based, or carmivore-based, is going to decrease your incidence of ALL cancers as well as chronic, western disease. Tell us something we DON'T know...🙄
mass-produced natural products, including fruits and veg's (basically the pre-packaged ones we'd buy at the supermarket) are not very healthy, since they're often heavily sprayed and treated with chemical fertilizer. this should be a major issue discussing natural and healthy food. BTW, what's with the potatoes?
A lot of these studies don't differentiate between potatoes prepared in healthy ways and French fries and potato chips.

Why do they keep on doing these studies? This is the umpteenth I see and you don't need to be a scientist to know this. Lots of taxpayer money being used for useless things. Put all these people to work in the fields and they will know by learning from their work instead of nosing their books
