Is celery an acidic or alkaline food?

There are mainly two types of food in our daily life: acidic food and alkaline food. Many people cannot distinguish between acidic food and alkaline food, and some people do not know whether celery is acidic or alkaline food. Judging from the content of inorganic salts, celery should be classified as alkaline food.

1. Is celery acidic or alkaline?

Nutrition experts say celery is an alkaline food, and the acidity and alkalinity of food cannot be determined simply by taste. The so-called acidity and alkalinity of food refers to whether the inorganic salts in the food are acidic or alkaline.

2. What are acidic foods?

Human food can be divided into acidic food and alkaline food. The acidity and alkalinity of food is not determined by people's taste or the chemical properties of food when it is soluble in water, but by the acidity and alkalinity of the final metabolites produced after the food enters the human body.

Protein, fat, carbohydrates, vitamins and minerals are the five elements of food. Minerals account for a small proportion of food, but they play an indispensable role in human health. There are eight trace elements related to the acidity and alkalinity of food: potassium, sodium, calcium, magnesium, iron, phosphorus, chlorine, and sulfur. Foods such as animal liver, meat, fat, protein, and grains contain more anions such as sulfur, phosphorus, and chlorine. After metabolism in the human body, they easily produce acidic substances such as lactic acid and phosphoric acid, and are therefore acidic foods.

The food we consume on a daily basis can be roughly divided into acidic foods and alkaline foods. From a nutritional point of view, a reasonable combination of acidic and alkaline foods is a guarantee of good health.

3. What are alkaline foods?

Alkaline food refers to food that produces alkaline substances after being digested and absorbed by the human body. The acidity and alkalinity of food are generally determined by the type and content of minerals contained in the food, not by the taste of the food.

Alkaline foods are rich in various trace elements, generally containing eight trace elements: potassium, sodium, calcium, magnesium, iron, phosphorus, chlorine, and sulfur. Because food contains these metal cations, after entering the human body, it undergoes metabolism and the final products make the body fluids alkaline, so it is alkaline food. Common alkaline foods include vegetables, fruits, legumes, etc. From a nutritional point of view, a reasonable combination of acidic and alkaline foods is a guarantee of good health.

However, some alkaline foods are special. For example, vinegar tastes acidic, but it produces carbon dioxide and water during metabolism in the human body, but no acidic substances. Therefore, vinegar is also an alkaline food.
