TOPLINE:
In patients with type 2 diabetes (T2D), eating more ultraprocessed food (UPF) increased the overall risk for microvascular complications and for diabetic kidney disease in particular. The risk was partly mediated by biomarkers related to body weight, lipid metabolism, and inflammation.
METHODOLOGY:
- A higher intake of UPF increases the risk for T2D and other metabolic morbidities; but whether this leads to an increased risk for diabetic microvascular complications remains largely unexplored.
- Researchers evaluated the association between the intake of UPF and the risk for diabetic microvascular complications in a prospective cohort of 5685 participants with T2D (mean age, 59.7 years; 63.8% men) from the UK Biobank.
- Dietary information of participants was collected with a web-based 24-hour dietary recall tool that recorded the frequency of consumption of 206 foods and 32 beverages.
- Researchers found five patterns that accounted for one third of UPF intake variation by estimated weight (not calories): Bread and spreads; cereal with liquids; high dairy and low cured meat; sugary beverages and snacks; and mixed beverages and savory snacks.
- The outcomes included the risk for overall microvascular complications; for diabetic retinopathy, diabetic neuropathy, and diabetic kidney disease; and for biomarkers related to microvascular complications.
TAKEAWAY:
- During a median follow-up duration of 12.7 years, 1243 composite microvascular complications were reported, including 599 diabetic retinopathy, 237 diabetic neuropathy, and 662 diabetic kidney disease events.
- Each 10% increase in the proportion of UPF consumption increased the risk for composite microvascular complications by 8% (hazard ratio [HR], 1.08; 95% CI, 1.03-1.13) and diabetic kidney disease by 13% (HR 1.13; 95% CI, 1.06-1.20). No significant UPF intake association was found with diabetic retinopathy or diabetic neuropathy.
- In the biomarker mediation analysis, body mass index, triglycerides, and C-reactive protein collectively explained 22% (P P
- The food pattern rich in sugary beverages and snacks increased the risk for diabetic kidney disease, whereas the pattern rich in mixed beverages and savory snacks increased the risk for composite microvascular complications and diabetic retinopathy.
IN PRACTICE:
“In view of microvascular complications, our findings further support adhering to the recommendations outlined in the American Diabetes Association’s 2022 guidelines, which advocate for the preference of whole foods over highly processed ones,” the authors wrote.

LIMITATIONS:
The dietary recall used in the UK Biobank was not specifically designed to collect dietary data according to the Nova food categories used in the study, which may have led to misclassifications. Data on usual dietary intake may not have been captured accurately, as all participants did not provide multiple dietary recalls. Individuals with T2D who completed dietary assessments were more likely to have a higher socioeconomic status and healthier lifestyle than those not filling the assessment, which could have resulted in an underrepresentation of high UPF consumers.
