Seeing is believing?

Recent research suggests that beetroot juice boosts stamina and could help you exercise for 16 per cent longer because the nitrate it contains reduces oxygen uptake which makes exercise less tiring.

In a double-blind, placebo-controlled, crossover study, eight males (aged 19-38 yr) consumed 500 mL per day of either beetroot juice (BR, containing 11.2 ± 0.6 mM of nitrate) or blackcurrant cordial (as a placebo, PL, with negligible nitrate content) for six consecutive days.

My question is – how on earth can you ‘blind’ anyone to the taste of blackcurrant & beetroot?
