Question

Quizplus · Accepted Answer

Scientists have suggested that the link between stomach illness and taste represents a biological propensity to learn taste aversions. This means that when we consume a food that makes us sick, our brains make an association between that food and the negative experience, causing us to avoid it in the future. This is thought to be an evolutionary adaptation to help us avoid potentially harmful foods.
