Hyperpalatable food (HPF) combines high levels of fat, sugar, sodium, and/or carbohydrates to trigger the brain's reward system, encouraging excessive eating.
[1] Researchers have proposed specific criteria for hyperpalatability based on the percentage of calories from fat, sugar, and salt in a food item.
A team at the University of Kansas analysed databases from the United States Department of Agriculture to identify the most common descriptive definitions for hyperpalatable foods.
[10] Hyperpalatable foods are often high in calories, fat, sugar, and salt, but low in nutrients, fibre, and water.
[11] Hyperpalatable foods are also linked to increased inflammation, oxidative stress, and gut dysbiosis, which can affect the immune system and the brain.
