Researchers from the University of La Laguna in Tenerife calculated the content of 20 macro and trace elements (Na, K, Ca, Mg, Al, B, Ba, Cd, Co, Cr, Cu, Fe, Mn, Mo, Li, Pb, Zn, Ni, Sr and V) in 72 yogurt samples using the method of Plasma Optical Emission Spectrometry (ICP-OES). The levels of metals detected did not reveal any toxicological risk for consumers. In the study, daily consumption of yogurt was established on 58.6 g for children and 42.1 g for an adult. The research results suggest that daily yogurt consumption contributes significantly to the dietary intake of essential metals and trace elements, mainly calcium (6.0% in children, 4.8% in adult women, and 4.3% in adult men) and zinc (2.0% in children, 1.2% in adult women, and 1.7% in adult men).
As a nutrient-dense food, yogurt contributes significantly to the intake of essentials nutrients, such as proteins and vitamins. New research in Tenerife found that daily yogurt consumption improves essential mineral intake, mainly Calcium and Zinc.
