A hormone is a chemical released by one or more cells that affects cells in other parts of the organism. Only a small amount of hormone is required to alter cell metabolism. It is essentially a chemical messenger that transports a signal from one cell to another.

Ultra-processed foods affect sperm quality and metabolism even without extra calories

A controlled crossover trial in Cell Metabolism found that ultra-processed foods increase weight, fat mass, LDL:HDL cholesterol, and alter reproductive hormones in men, with some effects independent of calorie load. These diets also showed trends toward reduced sperm motility, shifts in pollutants, and transient inflammatory responses, highlighting risks beyond excess calories.

Ultra-processed foods harm reproductive and metabolic health

Over the past 50 years, rates of obesity and type-2 diabetes have soared, while sperm quality has plummeted. Driving these changes could be the increasing popularity of ultra-processed foods, which have been linked to a range of poor health outcomes.
