Flavanol intake (mg/day)	2.9 ± 0.6^a	6.3 ± 0.21^b	0.6 ± 0.35^c	ND
Flavonol intake (mg/day)	21.8 ± 3.6^a	17.0 ± 1.3^a	6.3 ± 0.8^b	ND

Values are expressed as mean ± STD of 10 rats per group. Similar letters in rows denote lack of significant difference (P > 0.05), but if letters differ then P < 0.05. The daily intake is based on the respective beverage profiles provided in Table 1. ND: not done as these rats consumed tap water. Above intakes were based on fluid intake alone.
