Buttermilk is primarily due to lactic acid produced by lactic acid bacteria while fermenting lactose, the primary sugar in milk. As the bacteria produce lactic acid, the pH of the milk decreases and casein, the primary milk protein, precipitates, causing the curdling or clabbering of milk. This process makes buttermilk thicker than plain milk. While both traditional and cultured buttermilk contain lactic acid, traditional buttermilk tends to be less viscous, whereas cultured buttermilk is more viscous. Buttermilk can be drunk straight, and it can also be used in cooking. Soda bread is a bread in which the acid in buttermilk reacts
Sodium bicarbonate from incendiary bullets inside an afflicted soldier's wounds. Antacid (such as baking soda) solutions have been prepared and used by protesters to alleviate the effects of exposure to tear gas during protests. In a recent study published in the "Journal of Immunology", oral baking soda was found to activate a splenic anti-inflammatory pathway that seems to reduce the destructive inflammation of autoimmune diseases such as rheumatoid arthritis. Proinflammatory molecules were reduced and anti-inflammatory molecules were released. Similarly to its use in baking, sodium bicarbonate is used together with a mild acid such as tartaric acid as the excipient in effervescent
