Prebiotic effect of fruit and vegetable shots containing Jerusalem artichoke inulin : a human intervention study

The present study aimed to determine the prebiotic effect of fruit and vegetable shots containing inulin derived from Jerusalem artichoke (JA). A three-arm parallel, placebo-controlled, double-blind study was carried out with sixty-six healthy human volunteers (thirty-three men and thirty-three women, age range: 18–50 years). Subjects were randomised into three groups (n 22) assigned to consume either the test shots, pear-carrot-sea buckthorn (PCS) or plum-pear-beetroot (PPB), containing JA inulin (5 g/d) or the placebo. Fluorescent in situ hybridisation was used to monitor populations of total bacteria, bacteroides, bifidobacteria, Clostridium perfringens/histolyticum subgroup, Eubacterium rectale/Clostridium coccoides group, Lactobacillus/Enterococcus spp., Atopobium spp., Faecalibacterium prausnitzii and propionibacteria. Bifidobacteria levels were significantly higher on consumption of both the PCS and PPB shots (10·0 (sd 0·24) and 9·8 (sd 0·22) log10 cells/g faeces, respectively) compared with placebo (9·3 (sd 0·42) log10 cells/g faeces) (P < 0·0001). A small though significant increase in Lactobacillus/Enterococcus group was also observed for both the PCS and PPB shots (8·3 (sd 0·49) and 8·3 (sd 0·36) log10 cells/g faeces, respectively) compared with placebo (8·1 (sd 0·37) log10 cells/g faeces) (P = 0·042). Other bacterial groups and faecal SCFA concentrations remained unaffected. No extremities were seen in the adverse events, medication or bowel habits. A slight significant increase in flatulence was reported in the subjects consuming the PCS and PPB shots compared with placebo, but overall flatulence levels remained mild. A very high level of compliance (>90 %) to the product was observed. The present study confirms the prebiotic efficacy of fruit and vegetable shots containing JA inulin.

West is east: the Irish Saracens in 'Of Arthour and of Merlin'

Among the more striking episodes in the Middle English poem Of Arthour and of Merlin is an invasion of England by, amongst others, an army of gigantic Irish pagans. Adapted from the French Estoire de Merlin, the English poem’s depiction of the Irish represents one of the more intriguing points of divergence between the two versions. Of Arthour and of Merlin paints the Irish in a highly negative light and repeatedly refers to them as ‘Saracens’. The French text, by contrast, depicts the Irish as gigantic, but it does not suggest that they are ignoble or pagan. Although, the term ‘Saracen’ was sometimes applied to non-Islamic enemies of England, such as the Vikings, this appears to be its only application to a historically Christian people dwelling west of England. This paper argues that the depiction of the Irish in the poem reflects a complex of ideas about Ireland in circulation in England in the period. In particular, the influential writings of Gerald of Wales lay great emphasis on supposed Irish heterodoxy and repeatedly link the Irish Occident with the Orient as the furthest extremities of the world, abounding in marvels but rendered barbaric by their isolation
