Magnesium and trace element intake after a lifestyle intervention.
OBJECTIVE
Observational studies suggest that some trace elements and magnesium (Mg) improve glucose metabolism, markers of inflammation, and oxidative stress, but supplementation studies have yielded inconsistent results. Our objective was to evaluate whether a lifestyle intervention trial, aimed at reducing total and saturated fat and increasing fiber intake, can affect also the intake of selenium (Se), zinc (Zn), copper (Cu), chromium (Cr), and Mg.


METHODS
Dietary intake of Se, Cr, Zn, Cu, and Mg was evaluated at baseline and at the end of a lifestyle intervention trial performed in 335 dysmetabolic adults.


RESULTS
At baseline, trace element and Mg intake in the intervention (n = 169) and control (n = 166) groups of the trial were not significantly different. The former significantly increased their intake of Se, Mg, and Cr, while the latter reduced the intake of Mg, Zn, and Cr. Between-group differences were significant for Mg, Cr, and Se.


CONCLUSIONS
Healthier lifestyle recommendations might improve the pattern of micronutrient and Mg intake, which might play an independent role in ameliorating some metabolic, inflammatory, and oxidative markers.
