The following research articles give a broad slice of current nutrition science research relevant to clinicians.  A comprehensive systematic review by Chowdhury et al. concludes that the sum of current evidence does not support the relationship between the intake and circulating amounts of saturated fatty acids and increased risk for coronary heart disease. The three articles by McCartney et al., Wilson et al., and Shi et al. review the dietary contributors to hypertension and report on the broadly inverse association between riboflavin intake and blood pressure and the complex relationship involving the MTHFR 677TT genotype, prior use of antihypertensive medications, and obesity.  Rosanoff et al. review the relationship between intake and interactions of magnesium, calcium, and vitamin D, suggesting the need for closer clinical and investigative scrutiny of dietary intake and supplement ratios of these three nutrients. The next two articles by Bohm et al., and Brahe et al., explore the current clinical understanding of small intestinal bacterial overgrowth (SIBO), the role of gut microbiota in obesity-related metabolic diseases and the growing evidence that dietary modulation of gut microbiota may have application in metabolic disease prevention and treatment.  Finally, the last three articles by Krebs-Smith et al. and Fulgoni et al., review the current status of the typical American diet, where Americans get their nutrition, and micronutrient status of Americans.
