Using a water-based solution with this amino acid draws mercury out of fish and requires no additional production steps.An estimated 10% of Americans eat canned tuna at least once a week, according to a 2022 Consumer Reports survey. Consumer Reports also found that certain types of canned tuna can have unhealthy levels of mercury, which is particularly harmful for pregnant women. However, researchers from Chalmers University of Technology in Sweden say they've developed a new method of packaging that helps reduce mercury levels in each can. “Our study shows that there are alternative approaches to addressing mercury contamination in tuna,...

Decline in the hypothalamic Menin may play a key role in aging, according to a study. The findings reveal a previously unknown driver of physiological aging, and suggest that supplementation with a simple amino acid may mitigate some age-related changes. Leng and colleagues showed that Menin, a hypothalamic protein, is a key inhibitor of hypothalamic neuroinflammation. They observed that the level of Menin in the hypothalamus, but not astrocytes or microglia, declines with age. Another change was a decline in levels of the amino acid D-serine, known to be a neurotransmitter and sometimes used as a dietary supplement. The authors...

Nutrition, Metabolism & Cardiovascular Diseases — Lima A, Ferin R, Fontes A, et al.This study was intended to assess whether cysteine is a better prognosticator of coronary artery disease than conventional homocysteine in high-risk subjects under preventive medication. Researchers enrolled a total of 174 individuals with symptomatic coronary artery disease (CAD) (age 56±9y; 68% men) who submitted to coronary angiography were split into 2 groups: one formed by CAD patients (≥50% stenosis in at least one major coronary vessel) and the other by non-CAD patients (<50% stenosis). Via RP-HPLC/FLD, Plasma and erythrocyte aminothiol profiles were assessed. Compared with non-CAD group,...
