Levels of 2-arachidonoylglycerol (2-AG, A), anandamide (AEA, B), N -palmitoylethanolamine (PEA, C) and N -oleoylethanolamine (OEA, D) in the heart of high-fat fed mice with dietary krill oil (HFKO) supplementation at different doses (1.25, 2.5 and 5% wt). Data are means ± SEM of separate determinations in N = 4-5 mice. # P < 0.05 and ## P < 0.01 N vs HF; * P < 0.05 **P < 0.01 *** P < 0.001 high-fat diet (HF) vs HFKO1.25-2.5-5. N = normal diet.
