The Portfolio Dietary Pattern significantly reduces systolic and diastolic blood pressure, as well as C-reactive protein (inflammation), compared to a standard NCEP Step II diet.
In addition to lowering cholesterol, the Portfolio Dietary Pattern helps reduce blood pressure and inflammation (measured by CRP). By consuming specific plant-based foods daily, you can achieve modest but significant improvements in these cardiovascular risk factors compared to a standard low-saturated-fat diet.

The Portfolio dietary pattern lowered SBP by 1% (7 trial comparisons, MD = −1.75 mmHg [95% CI: −3.23 to −0.26 mmHg], p = 0.02) and DBP by 2% (7 trial comparisons, MD = −1.36 mmHg [95% CI: −2.33 to −0.38 mmHg], p = 0.006) ... The Portfolio dietary pattern lowered CRP by 32% (7 trial comparisons, MD = −0.53 mg/L [95% CI: −1.01 to −0.15 mg/L], p = 0.008)
Why this rating
Moderate certainty of evidence due to serious imprecision.
