Main findings related to principal component analysis (PCA) derived dietary patterns and health in Blacks from the REGARDS study.

Year	Author(s)	Health Focus	Outcomes	Reference
2019	Lara et al.	Heart failure	PBP a = 41% lower heart failure risk SDP b = 72% higher heart failure risk	[130]
2016	Pearson et al.	Cognition	PBP = higher learning and memory scores than SBP	[113]
2016	Akinyemiju et al.	Cancer mortality	PBD decreased cancer mortality risks in Whites, but not in Blacks
2015	Suwaidi et al.	Acute CHD	SDP = 56% increased risk, while PBP protective	[129]
2015	Gutierrez	Sepsis	SDP = increased sepsis risk, especially in Blacks PBD = reduced sepsis risk, although still higher in Blacks than Whites
2014	Gutierrez	ESRD mortality	PBD reduced ESRD c mortality risk SDP increased ESRD mortality risk	[131]
2013	Judd et al.	Stroke	Adherence to a Southern dietary pattern increased stroke risk by 39% Adherence to a PBD was protective against stroke in Blacks (HR d 0.71; CI e 0.56–0.91)	[128]
