Study Links Ultra-Processed Foods to Decline in Attention Span
A recent study published in the journal Alzheimer's & Dementia: Diagnosis, Assessment & Disease Monitoring has found a correlation between the consumption of ultra-processed foods (UPFs) and a decline in attention span. The research analyzed data from over 2,100 middle-aged and older adults in Australia, using the NOVA system to classify food based on processing levels. Participants who increased their UPF intake by 10%—equivalent to a standard bag of chips—experienced a 0.05 point drop in attention scores. The study also noted slightly higher scores on dementia risk indicators among these individuals. Experts suggest that UPFs might reduce focus by displacing nutrient-dense foods that support brain health, or due to their high sugar and salt content causing energy crashes.
