Superfoods: The real story, was shown on Channel 4 (20.07.2016 ). It features Nourish Kefir watch at this link
We had a wonderful day when the crew came to visit us and record us making kefir for their episode. Kate was drinking kefir at our premises on the day, which is before she took part in the scientific study – so her ‘before’ samples already had kefir in them… this will have skewed the results from the analysis, because she would have needed to have not had any kefir in her first sample, so that the ‘after’ sample would give a more authentic result.
