Had she killed Lydia? Daryl asked. Back in the present? Later, Alpha told Beta that she wanted to be left alone, then murdered the Whisperer who caught a glimpse of her shedding real, human tears. Later, Siddiq addressed the communities that had gathered at the fair. So, your reaction to the big heads-on-a-stake scene? Anyone you cared about enough to be sorry they were beheaded? Were you relieved that Ezekiel and Rosita were spared their comic-book fates?

Other nut studies have either not assessed 13 or have not detected any significant differences in alpha-diversity 10—12 , Increased microbiome diversity could promote greater stability of the microbiome in the long term, thereby contributing to functional resilience against extreme stress and perturbations as purported by the classical ecological resilience theory 38 , Another important finding of the present study was the decrease in B.
Although enterotoxins produced by specific B. We did not assess inflammatory profiles or immune system markers in this study; however, Sugizaki and Naves 6 propose that the dietary fiber and polyphenol component of nuts can promote a homeostatic intestinal state via host—microbe interactions. The taxa characterizing the structural redundancy were mostly similar at both time points of the intervention with the notable contributions of classes Mollicutes phylum Tenericutes , which was predominantly composed of the order RF39, and Coriobacteriia phylum Actinobacteria , which was mostly composed of the family Coriobacteriaceae at week 8 of the intervention.
The relation between bacteria in the order RF39 and the host's metabolism is not defined. However, twin studies demonstrated that an increased abundance of RF39 was associated positively with a lean phenotype 43 and negatively with metabolic syndrome The Coriobacteriaceae in the gut could contribute to the modulation of bile acid, steroid, and dietary polyphenol metabolism Other favorable changes in the gut microbiome profile over the 8-wk intervention involved a decrease in Alistipes phylum Bacteroidetes , which is indicative of a shift away from an animal-based diet, and increase in Lachnospira phylum Firmicutes , which are pectin degraders Additionally, a decrease in the butyric acid producers, Odoribacter and Butyricimonas Bacteroidetes genera , was observed over 8 wk.
Although a decrease in butyric acid—producing potential is typically associated with cardiometabolic disorders 47 , an increase in butyric acid producers of the order Bacteroidales was reported in murine models of colitis 48 , As noted before, in times of physiological stress such as inflammation, there can be an increased reliance of colonocytes on butyric acid for energy, hence promoting the growth of butyric acid producers Thus, it can be postulated that a decrease in stress can reduce the reliance on butyric acid producers.
In addition, the abundance of uncultured Bacteroidetes family S decreased over 8 wk, but this has not been well studied in humans. However, murine studies report conflicting effects of diets on S in obese and diabetes models 50— The association of carbohydrate and fiber intake with the underlying community structure is not surprising because these are the principal energy sources for bacteria Additionally, we have demonstrated that incorporating a morning snack into the diet of these predominantly breakfast-skipping college freshmen improved fasting glucose, and total and LDL cholesterol, with a protective effect of almond consumption on HDL cholesterol Hence, changes in cholesterol profiles could partly be related to the gut microbiome composition.
In some studies, intrinsic factors outweighed dietary intervention and drove community structure 54 , whereas in others, dietary factors that were significantly associated with interindividual variation of gut microbiome outnumbered other intrinsic factors Hence, intra- and inter-individual factors such as genetics and environment 43 could have a greater influence on the gut microbiome composition. Developing statistical models for analyzing differential abundance of taxa is an active area of research. Compositional data such as relative abundances exist in the simplex rather than Euclidean space, that is, relative abundances across all taxa sum to 1 within a given sample.
Because standard statistical tests such as t test, ANOVA, linear regression, and others do not account for the simplex nature of compositional data, they should not be directly used for analyzing relative abundance data. The ANCOM method is a highly sensitive statistical framework that uses Aitchison log-ratios to test for differences in the mean abundances of log-transformed taxa, which can be used to draw inferences regarding relative abundance differences in the ecosystem 20 represented by the gut here.
The ANCOM method controls the false discovery rate, while maintaining high power 20 , 56 , and can incorporate standard statistical tests within the framework. Strengths of the study included: 1 excellent participant compliance 15 , 2 the use of high-resolution ASVs, and 3 the incorporation of the sensitive and powerful ANCOM method for analyzing differential abundance.
However, the 16S taxonomic resolution concerns are partly mitigated by sequencing ASVs 57 of the V4 and V5 variable regions. In conclusion, almond snacking for 8 wk led to greater alpha-diversity than the isocaloric cracker group in college freshmen.
In addition, almond snacking decreased the relative abundance of B. In general, incorporating a morning snack in the dietary regimen of predominantly breakfast-skipping college freshmen improved the diversity and composition of the gut microbiome.
