Mnu36-003	Effects of Walnut Supplementation on Short-Chain Fatty Acid Levels in Healthy Volunteers
	Quote:	Walnut intake was associated with an overall 2.8 increase in alpha diversity, a 17.6 reduction in estimated marginal mean F/B ratio, and an overall reduction in three luminal proteolytic metabolites associated with gut dysbiosis: isobutyric acid, valeric acid, and isovaleric acid. Interestingly, the effects on the gut metabolome were more pronounced in obese individuals, with significant decreases observed in the same three SCFAs, as well as p-cresol. Given the known associations between these luminal proteolytic metabolites and gut dysbiosis, these results suggest that walnut intake may help to attenuate overall gut dysbiosis, particularly in obese populations.

	Quote:	Thus, low BMI exhibits low diagnostic sensitivity in modern U.S. cohorts. Excluding BMI successfully bypasses circularity, unmasks qualitative muscle wasting under excess body weight, and establishes a robust, weight-independent standard for clinical and epidemiological research.

Sd363-016	Popular Brain Supplement Linked to Shorter Lifespan in Men
	Quote:	Researchers led by Jie V. Zhao, Yitang Sun, Junmeng Zhang, and Kaixiong Ye from the University of Hong Kong and the University of Georgia examined whether phenylalanine and tyrosine, two amino acids involved in metabolism and brain function, are connected to lifespan (lifespan). Their results point to a notable difference between men and women. Higher tyrosine levels were associated with shorter life expectancy in men, while no significant effect was detected in women.
