Complementary diet affects late-infancy gut microbiota composition. (A) Macronutrient intake in SKOT I and II is expressed as a mean percentage of total energy intake (E%) from carbohydrates, protein, and fat, whereas fiber intake is expressed in milligrams per kilojoule, with error bars indicating standard deviations. (B and C) PCA plot of consumption of the 23 food groups (grams per day per kilogram of body weight) for each individual in SKOT I and II (n = 217), resulting in principal component 1 (PC1), designated family food, and PC2, designated health-conscious food. (D) Heatmap illustrating hierarchical clustering of Spearman’s rank correlations between relative abundances of family-level gut microbes and macronutrient intake. *, P < 0.05; **, P < 0.01; ***, P < 0.001. (E and F) Spearman’s rank correlations between family food and relative abundances of Bifidobacteriaceae and Lachnospiraceae. q values are false-discovery-rate-corrected P values.
