Even a small amount of ultra-processed foods can lead to increased weight, hormone disruption, and poor sperm quality in men, finds a study.

An international team of scientists has now discovered that people gain more weight on an ultra-processed diet compared to a minimally processed diet, even when they eat the same number of calories.

The study, published in the journal Cell Metabolism, in humans also revealed that a diet high in ultra-processed foods introduces higher levels of pollutants that are known to affect sperm quality.
