Dementia risk rises with common food type millions eat every day, study suggests
A study published in the journal Alzheimer’s and Dementia suggests that higher consumption of ultraprocessed foods (UPFs) is linked to increased dementia risk and lower attention scores, regardless of overall diet quality. Researchers analyzed over 2,000 dementia-free adults aged 40 to 70 and found that each 10% increase in UPF intake correlated with poorer cognitive performance. The findings support revising dietary guidelines to emphasize the negative impact of food processing on brain health.
- ▪Ultraprocessed foods are associated with more than 30 adverse health outcomes, including cardiovascular disease, type 2 diabetes, and obesity, which are risk factors for dementia.
- ▪Each 10% increase in ultraprocessed food consumption was linked to lower attention scores, even among those following otherwise healthy diets like the Mediterranean diet.
- ▪The study did not find a significant association between ultraprocessed food intake and memory decline, and relied on self-reported dietary data, which may limit the strength of its conclusions.
