Consuming ultra-processed foods makes people fat, a new study conducted at the National Institutes of Health finds. People eating highly processed foods are more likely to eat more quickly and have more fats and carbohydrates, the research shows. They take in more calories, hence, gain more weight compared to those who stick to a minimally processed meal, the study published in the journal Cell Metabolism reveals.

Ultra-processed foods are those that contain industrial ingredients, such as hydrogenated oils, high-fructose corn syrup, flavouring agents and emulsifiers.
