Joseph's "Just My Thoughts"

Human blood is a liquid that maintains a pH between 7.3 and 7.4. A change of just 0.2 in pH can be fatal. The substance responsible for regulating blood pH is carbonic acid. When carbonic acid dissolves in the blood, it creates a cooling sensation, contributing to the appeal of drinking soda. Humans convert food into glucose through digestion for energy, and this glucose combines with oxygen in a process called breathing to generate carbon dioxide, water, and ATP, which are essential for energy production. A significant amount of carbon dioxide is produced in this process. To meet a daily energy requirement of 2,560 calories, one needs to burn 640 grams of glucose with oxygen, resulting in the production of 938 grams or 552 liters of carbon dioxide. When carbon dioxide dissolves in water, it forms carbonic acid, which circulates in the bloodstream and exits the body through the lungs. While some argue that soda is unhealthy, especially for individuals with specific conditions, it is es...

The human tongue identifies five distinct tastes. With the exception of sourness, the other tastes alert us to vital nutrients necessary for human survival. So, what is the importance of acidity? The sensation of sourness arises from the concentration of hydrogen ions (H+) present in water. As the concentration of hydrogen ions rises, the pH level lowers, leading to increased acidity and a stronger sour flavor. Sourness is both the most appreciated and least favored taste among humans. We utilize the scent of decay along with the sour flavor to differentiate between edible and inedible food. When ripening occurs appropriately, it is termed “fermentation,” while excessive ripening is referred to as “rotting.” Fermentation indicates that food is safe to eat, whereas rotting signifies that it should be discarded. In essence, acidity is fundamentally tied to human survival. - Joseph’s “just my thoughts”
