Want to reduce your risk of developing chronic disease and live longer  while also helping the planet? Eat a plant-based diet, experts say.

Does that mean you can fill your plate with boxed macaroni and cheese, deep-dish frozen veggie pizza or fast-food French fries and have a doughnut or three for dessert?

While all of those ultraprocessed choices may be meat-free, they are not without risk, said Duane Mellor, a registered dietitian and senior teaching fellow at Aston Medical School in Birmingham, United Kingdom.

In fact, eating such plant-based junk foodsdramatically raises bad cholesterol and hypertension and can lead to associated heart disease and early death, according to a new study authors call “the first” to show ultraprocessed plant foods are associated with an increase in the risk of cardiovascular diseases.
