What is acidity?

What Does acidity Mean

Acidity is the quality of acid , that which tastes like sour grapes or vinegar . When excess acid is produced in the stomach, the person suffers from heartburn, a discomfort that affects various aspects of life.

Heartburn
The regurgitation of gastric acid causes what is known as heartburn , a sense of burning in the esophagus. Some of the foods and drinks that can cause heartburn are red wine, chocolate, caffeinated drinks, mint, coffee, and spicy ingredients. Other triggers for this discomfort, which is also known as "heartburn," are overeating, being overweight, nicotine, and pregnancy. When this disorder occurs very often, it is advisable to seek professional help.

However, as with most ailments, there is a long list of home remedies and tips to avoid this state of heartburn. The first failure that occurs when suffering from this disorder is that the lower esophageal sphincter , responsible for containing stomach acids, gives way. Certain foods are very effective in preventing this very important component of the digestive system from relaxing and allowing stomach contents to flow up the esophagus; among them are:
oatmeal : many doctors recommend it especially to patients who suffer from heartburn, since it can be ingested at any time of the day and is accessible and nutritious ;
bananas : although their pH level (5.6) makes them ideal for treating this type of gastric discomfort, some people seem not to obtain good results from their consumption;
melon : in the same way as bananas, this fruit seems to generate opposing opinions, although the majority of people who consume it to relieve or avoid heartburn are satisfied with its action;
fennel : a not very popular vegetable, but in this case it is very effective, and it also helps with the digestion process. It is worth mentioning that it is a perfect companion to a salad;
parsley : it does not need an introduction, since it is one of the best known and most used condiments in the kitchen, since it is extremely inexpensive and tasty, improves digestion and avoids discomfort such as acidity;
brown rice : unlike white rice, it is very practical for cold dishes such as salads and is easier to preserve. In this case, it proves to be an excellent food for those who suffer from heartburn.
On the other hand, to calm the acidity, it is advisable to prepare an infusion with boiled water and two tablespoons of anise , and let it settle for ten minutes before drinking it. Other homemade recipes include ingredients like lettuce, cloves, and cinnamon.

Other meanings
The term acidity also refers to the amount of free acid found in resins, oils and wines, which is determined through titration with a basic reagent. The result is expressed as a percentage (%). On the other hand, acidity is the abundance of hydrogen ions in an aqueous solution (compared to the ions present in pure water).
The basicity is the concept that complements the acidity. The pH is the scale that allows, in aqueous solutions, to quantify acidity or basicity. Outside of this type of solution, it is possible to compare the acidity in different elements, such as the gases carbon dioxide, sulfur trioxide and dinitrogen.
It can be distinguished between two types of acidity: on the one hand, natural acidity is that produced by the natural composition of the substance; on the other hand, the acidity developed is obtained from microbiological, thermal or enzymatic processes that generate the acidification of the component.
