Vinegar is an alkaline food.

Vinegar tastes sour, but why is it said to be an alkaline food? This requires first understanding what are acidic foods and what are alkaline foods.

Foods containing a lot of non-metallic elements such as nitrogen, sulfur, and phosphorus are called acidic foods because their final metabolites after being ingested by the human body are acidic. Common acidic foods mainly include: fish, meat, poultry, eggs, grains such as rice, corn, and white flour, and nuts such as peanuts, hazelnuts, and walnuts. Foods containing more metal elements such as sodium, potassium, calcium, and magnesium are called alkaline foods because their final metabolites after being ingested by the human body are alkaline. Common alkaline foods include: vegetables, fruits, milk, soybeans, almonds, chestnuts, coconuts, etc.

That is to say, acidic foods and alkaline foods are not determined by taste. For example, it is unscientific to say that some fruits are acidic foods because they taste sour. The body fluids of healthy people are weakly alkaline (pH value is 7.3-7.4). However, due to the decomposition of food in the body, pyrogluconic acid, lactic acid, and fatty acids are produced, and due to work fatigue, excessive diet, excessive drinking, etc., residual substances in the body are If not removed, harmful residue will be produced, thus causing fatigue. At this time, human body fluids are weakly acidic (PH value is 6.8-7).

Japanese scholar Nagata Masamatsu has been studying the medical functions of vinegar since 1971. He believes that among all drugs and foods, vinegar is the only food that can directly make human body fluids appear normal and weakly alkaline. The vinegar he mentioned includes acetic acid and citric acid in edible vinegar. Acetic acid is an organic acid and is acidic. How can it make lactic acid and pyrogluconic acid become weakly alkaline in the body? The British scholar Kribbs discovered the "Krebs cycle", for which Kribbs won the 1953 Nobel Prize in Chemistry. In this cycle, acetic acid combines with lactic acid, and citric acid and pyrogluconic acid combine (react) to release carbon dioxide and water. The carbon dioxide is excreted from the lungs, thus reducing the carbonic acid content in the blood and making the body fluids slightly alkaline. . People's urine will become clear 2 hours after taking vinegar. Vinegar can also make people feel delicious about any food. This is why humans taking appropriate amounts of vinegar can eliminate fatigue, improve their ability to prevent diseases, and maintain long-term health.

So, vinegar is an alkaline food.
