Exploratory study of acid-forming potential of commercial cheeses: impact of cheese type

Abstract

Due to their composition, cheeses are suspected to induce an acid load to the body. To better understand this nutritional feature, the acid-forming potential of five cheeses from different cheese-making technologies and two milk was evaluated on the basis of their potential renal acid load (PRAL) index (considering protein, P, Cl, Na, K, Mg and Ca contents) and organic anions contents. PRAL index ranged from -0.8 mEq/100g edible portion for fresh cheese to 25.3 mEq/100g for hard cheese Cantal and 28 mEq/100g for blue-veined cheese Fourme d'Ambert. PRAL values were greatly subjected to interbatch fluctuations. This work emphasized a great imbalance between acidifying elements of PRAL calculation (Cl, P and proteins elements) and alkalinizing ones (Na and Ca). Particularly, Cl followed by P elements had a strong impact on the PRAL value. Hard cheeses were rich in lactate, thus, might be less acidifying than suspected by their PRAL values only.
