Recently, in a three monocentric, parallel-arm, double-blind, randomised, dietary intervention trial, 250 mg DHA and 320 mg grape anthocyanins administered as bioactive-enriched foods, for 4 weeks, had positive effects on serum triglyceride or HDL levels (Bub et al., 2019). These results are partially in line with a later cross-sectional analysis in the Korean population that suggested beneficial effects exhibited only in men by high amounts of proanthocyanidins or n-3 PUFAs on HDL levels. In addition, n-3 PUFAs intake increased polyphenols uptake (Ahn et al., 2020).
