For most comparisons , the credibility of evidence was rated very low to moderate , with the exception for the DASH vs. the low-fat dietary approach for which the quality of evidence was rated high .
Conclusion : The present network meta- analysis suggests that the DASH dietary approach might be the most effective dietary measure to reduce blood pressure among hypertensive and pre-hypertensive patients based on high quality evidence
ABSTRACT Background : Pairwise meta-analyses have shown beneficial effects of individual dietary approaches on blood pressure but their comparative effects have not been established .
Objective : Therefore we performed a systematic review of different dietary intervention trials and estimated the aggregate blood pressure effects through network meta- analysis including hypertensive and pre-hypertensive patients .
Vegetable protein and fiber from cereal are inversely associated with the risk of hypertension in a Spanish cohort.
BACKGROUND Some cross-sectional studies suggest that fiber and protein intake can be associated with lower levels of blood pressure , but results from prospect i ve cohorts are scarce and none has been conducted outside the U.S. METHODS The SUN cohort followed-up prospect ively 5880 Spanish men and women older than 20 years of age , all university graduates . Dietary information was gathered at baseline with a previously vali date d semiquantitative food frequency question naire . New cases of medically diagnosed hypertension ( HT ) were identified through responses to a mailed question naire after at least 2 years from recruitment . RESULTS One hundred and eighty new cases of HT were ascertained after a median follow-up of 28 months . After adjustment for potential confounders and several dietary factors , participants in the highest quintile of vegetable protein intake had a lower risk of incident HT compared with those in the lowest quintile [ hazard ratio ( HR ) = 0.5 , 95 % confidence interval ( CI ) 0.2 - 0.9 , p for trend = 0.06 ] . Similarly , fiber from cereals was inversely associated with a lower risk of HT ( HR comparing fifth vs. first quintile = 0.6 , 95 % CI 0.3 - 1.0 , p for trend = 0.05 ) . Risk reduction was more important among men and obese and older individuals . Total or animal protein and total fiber as well as fiber from other sources different from cereal were not associated with the risk of HT . CONCLUSIONS In this Mediterranean cohort , dietary intake of vegetable protein and fiber from cereals was associated with a lower risk of HT when other nutrients were also taken into consideration
For most comparisons , the credibility of evidence was rated very low to moderate , with the exception for the DASH vs. the low-fat dietary approach for which the quality of evidence was rated high .
