Rather than treating ultra-processed food as one category, German researchers broke it into nine groups of specific additives and followed 101,560 UK Biobank participants for a median of ten and a half years. Only four of the nine additive categories tracked with new hypertension. Five showed no association at all, and three specific additives ran the other way.

Pooling 12 randomised trials, ginger supplementation was associated with a 5.03 mmHg drop in systolic and a 2.03 mmHg drop in diastolic blood pressure, with larger reductions in trials that used 2000 mg a day or more. The authors rate the certainty of their own evidence as low, because the trials disagree with each other.

Published on 5 June 2026, this UK Biobank analysis of 124,836 adults found that people sticking closely to a healthy plant based pattern had lower rates of death, type 2 diabetes and cardiovascular disease whether that pattern was high or low in ultra processed food. The authors read this as diet quality mattering more than processing level.
