Each control (non-supplemented) animal received a 100% of A04 maintenance diet (Panlab, Barcelona, Spain). Each supplemented animal received an 80% of A04 maintenance diet plus 20% of cereal fractions (B, C, D or E) naturally rich in polyphenols. B = wheat germ; C = buckwheat flour; D = fine rice bran; E = wheat middlings. ORAC (μTrolox Equivalents/g): B = 106; C = 81; D = 121; E = 49. Total polyphenols content (eq mg gallic acid/g): B = 11.15; C = 8.48; D = 15.24; E = 9.35. HF (mg/100g) = hydrosoluble fraction; LF (mg/100mg) = lyposoluble fraction; p-HB = p-hydroxybenzoic. amg/100 g. bmg/100 mg. cμg/100 g. dg/100 g
