Research: Berries are associated with health benefits. Little is known about the effect of baseline metabolome on the overall metabolic responses to berry intake. Researchers studied the effects of berries on serum metabolome in this randomized crossover study involving 80 overweight women.
During the interventions of 30 days, subjects consumed dried sea buckthorn berries (SBs), sea buckthorn oil (SBo), sea buckthorn phenolics ethanol extract mixed with maltodextrin (SBe+MD) (1:1) or frozen bilberries. Metabolic profiles were quantified from serum samples by using 1H nuclear magnetic resonance spectroscopy.
Results: All interventions induced a significant (P < 0.001–0.003) effect on the overall metabolic profiles. The effect was observed both in participants who had a metabolic profile that reflected higher cardiometabolic risk at baseline (group B: P= 0.001–0.008) and in participants who had a lower-risk profile (group A: P < 0.001–0.009). Although most of the changes in individual metabolites were not statistically significant after correction for multiplicity, clear trends were observed.
SB-induced effects were mainly on serum triglycerides and very-low-density lipoprotein (VLDL) and its subclasses, which decreased in metabolic group B. SBo induced a decreasing trend in the serum total, intermediate-density lipoprotein (IDL) and low-density lipoprotein (LDL) cholesterol, and subfractions of IDL and LDL in group B.
During the SBe+MD treatment, VLDL fractions and serum triglycerides increased. Bilberries caused beneficial changes on serum lipids and lipoproteins in group B, whereas the opposite was true in group A.
Researchers concluded that berry intake has overall metabolic effects, which depend on the cardio-metabolic risk profile at baseline. This trial was registered at clinicaltrials.gov as NCT01860547.
