The brain's association of flavors with nutrient content may be impaired by ultra-processed foods.

“perhaps if these Ultra processed foods that have so many different ingredients and such an unnatural combination perhaps this process of learning about the nutrient content of different foods and flavors becomes impaired because it's just the brain is not used the brain's used to saying you know this is a piece of chicken and this is primarily protein and so I can gauge you know from this Flav I can connect this flavor to an amino acid content but something that's so diverse it might be harder to do”
