The Claim

Adherence to unhealthy plant-based diets, irrespective of ultra-processed food content, is associated with a 13% to 31% increased risk of type 2 diabetes and a 9% to 13% increased risk of all-cause mortality, indicating that poor nutrient quality negates any potential benefit from reduced food processing.

In plain English

People who follow plant-based diets high in low-nutrient foods have a higher risk of developing type 2 diabetes and dying from any cause, regardless of whether those foods are ultra-processed, because the poor nutritional quality outweighs any benefit from less processing.

See the scientific wording

Adherence to unhealthy plant-based diets, regardless of ultra-processed food content, is associated with a 13% to 31% higher risk of type 2 diabetes and a 9% to 13% higher risk of all-cause mortality, indicating that poor nutrient quality overrides any potential benefit from lower food processing.

Why this might work

Eating too many sugary drinks, refined grains, and added sugars causes blood sugar to stay high all the time. This forces the pancreas to make more insulin, and over time, the body’s cells stop responding to it. High blood sugar also triggers inflammation throughout the body, which further blocks insulin action. These changes make it harder for the body to control blood sugar, leading to type 2 diabetes and damage to organs that increases the risk of early death.

    Even if a diet is plant-based, if it’s full of sugary drinks and white bread, it still raises your risk of diabetes and early death—no matter if those foods are processed or not. What you eat matters more than how processed it is.
