Citric acid is crucial in the krebs cycle (tricarboxylic acid cycle or citric acid cycle) which is part of cellular respiration involved in human metabolism. This helps with the oxidation of fats, proteins and carbohydrates. It is a series of enzyme-catalysed chemical reactions that form a key part of the aerobic respiration in cells and break down glucose into usable energy.
Despite being an acid, citric acid is an alkalising agent. It can decrease the level of acidity in body fluids. Citric acid’s ability to bind to calcium and its alkalising properties make it useful as a method for preventing kidney stones as well as treating several other kidney ailments. It also associates itself with other minerals such as calcium, magnesium and zinc easily, a trait which accelerates their absorption into the body.
Consuming juices from any of the following food sources, which are rich in citric acid, can quickly and effectively eliminate nausea by reducing the gastric acidity.
