Early Neolithic Pits at Principal Place, Shoreditch, London Borough of Hackney
A group of four pits excavated in the upper Walbrook valley at Principal Place, Shoreditch by MOLA in 2015 produced the largest assemblage of Early Neolithic Bowl pottery recovered to date from the City of London and its immediate surrounds. The Neolithic pits had been fortuitously preserved within part of the northern extramural Roman cemetery of Londinium and conjoining sherds of Bowl pottery were also recovered from the fill of an isolated late Roman cremation. A range of analyses showed that the vessels – comprising essentially Plain Bowl with some Decorated Bowl, the latter incorporating Peterborough Ware traits – were probably locally made and had been used to process dairy products and to stew beef and mutton (though not pork). Radiocarbon dating of the lipids absorbed within the vessel walls – employing a novel technique developed at the University of Bristol – suggest that the pottery was being used in the mid-fourth millennium cal BC. The pits also contained small assemblages of struck flint, fauna (some burnt) and archaeobotanical remains (some intrusive) and may have been filled using material drawn from a long-vanished ‘pre-pit’ source, possibly a midden; they presumably represent episodic activity on the part of semi-sedentary Neolithic communities
Genetic differences in fat taste sensitivity and dietary intake in a UK female cohort
Over the past decade, a potential sixth taste, fat taste (“oleogustus”), has been identified. Studies in adults and
children of various ethnicities have demonstrated that both lifestyle and genetic factors may contribute to fat taste sensitivity (FTS). Data on females in the UK is limited. The aim of this study was to determine, using an ethnically similar, healthy, female cohort, whether known genotypes related to fat taste and dietary intake lead to differences in FTS. A cross-sectional study was carried out on a UK cohort of Caucasian females (32.7 ± 11.4 years, 23.7 ± 3.6 kg/m2). We report that FTS differed in individuals with differing genotypes; genotypes that have previously been associated with differences in dietary intake. Specifically, FTS was lower in rs1514175 Troponin I-Interacting Protein Kinase (TNNI3K) gene AA/AG genotype and was higher in rs6265 Brain Derived Neurotrophic Factor (BDNF) gene TT/CT genotype (both p < 0.05). We also report that participants in the
rs1514175 TNNI3K AA/AG genotype group had a higher energy intake, total fat intake, and subsequently, higher monounsaturated fat and saturated fat intake when compared to the GG genotype (all p < 0.05). To our knowledge, this is the first study showing associations between genotypes that have been previously associated to dietary intake are also associated to FTS. Due to the heterogeneity of previous research and the infancy of fat taste research, further research is required on a larger, ethnically similar cohort
