Livelli di fosforo, potassio e calcio nei prodotti alimentari biologici e convenzionali: una ricerca tedesca

Uno studio tedesco,  BfR MEAL , ha analizzato 356 prodotti alimentari e ha trovato livelli simili di fosforo (P), potassio (K) e calcio (Ca) tra prodotti biologici e non biologici (convenzionali). Differenze significative sono emerse per le olive: Ca più basso, forse dovuto all'additivo cloruro di calcio usato nel sistema convenzionale, K più alto, forse nel sale marino usato per le olive biologiche e P più alto, attribuito dagli autori (sorprendentemente) ad un uso più elevato  di fertilizzanti per le olive biologiche.

Results of the BfR MEAL Study: The food type has a stronger impact on calcium, potassium and phosphorus levels than factors such as seasonality, regionality and type of production

Published in “Food Chemistry”. The BfR MEAL Study aims to provide representative levels of chemical substances in foods consumed by the population in Germany for dietary exposure assessment. Calcium, potassium and phosphorus (Ca, K, P) are essential to obtain physiological functions in humans. Levels were investigated in 356 foods. Foods were purchased representatively, prepared as typically consumed and pooled before analysis.

A Systematic Review of Organic Versus Conventional Food Consumption: Is There a Measurable Benefit on Human Health?

The current review aims to systematically assess the evidence related to human health outcomes when an organic diet is consumed in comparison to its conventional counterpart. Relevant databases were searched for articles published to January 2019. Clinical trials and observational research studies were included where they provided comparative results on direct or indirect health outcomes. Thirty-five papers met the criteria for inclusion in the review.
