The Claim
Moderate consumption of dry-cured Iberian ham (40–120 g/day) for 4–8 weeks is associated with a small but statistically significant reduction in diastolic blood pressure by approximately 1.64 mmHg in adults.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Eating 40 to 120 grams of dry-cured Iberian ham per day for 4 to 8 weeks is linked to a small decrease in diastolic blood pressure by about 1.64 mmHg in adults.
See the scientific wording
Moderate consumption of dry-cured Iberian ham (40–120 g/day) for 4–8 weeks is associated with a small but statistically significant reduction in diastolic blood pressure by approximately 1.64 mmHg in adults, suggesting a potential benefit for vascular health that may contribute to population-level cardiovascular risk reduction, though clinical relevance at the individual level remains uncertain due to short duration and heterogeneity.
Proteins in the ham break down during curing into small molecules that enter the bloodstream and block an enzyme that normally tightens blood vessels. This causes blood vessels to relax, reducing pressure in the arteries during heart relaxation.
What the research says
1 studyEating a small amount of this special ham for a few weeks slightly lowered the bottom number in people’s blood pressure readings, which might help reduce heart disease risk for lots of people over time—even if it doesn’t make a big difference for one person.
