Magnesium and trace element intake after a lifestyle intervention

Area of Science:

• Nutrition Science
• Metabolic Health
• Trace Element Research

Background:

• Observational studies suggest trace elements and magnesium (Mg) benefit glucose metabolism, inflammation, and oxidative stress.
• Supplementation studies show inconsistent results regarding these benefits.
• Lifestyle interventions focusing on diet may influence micronutrient intake.

Purpose of the Study:

• To assess if a lifestyle intervention impacts the intake of selenium (Se), zinc (Zn), copper (Cu), chromium (Cr), and Mg.
• To evaluate changes in dietary intake of specific minerals in adults with dysmetabolism.

Main Methods:

• A lifestyle intervention trial involving 335 adults with dysmetabolism.
• Dietary intake of Se, Cr, Zn, Cu, and Mg was assessed at baseline and post-intervention.
• Participants were divided into an intervention group (n=169) and a control group (n=166).

Main Results:

• No significant baseline differences in trace element and Mg intake between groups.
• The intervention group increased intake of Se, Mg, and Cr.
• The control group decreased intake of Mg, Zn, and Cr, with significant between-group differences observed for Mg, Cr, and Se.

Conclusions:

• Healthier lifestyle recommendations can positively alter micronutrient and Mg intake patterns.
• Improved mineral intake may independently contribute to better metabolic, inflammatory, and oxidative markers.
