Food is an acidic substance.

Foods can be divided into three categories: alkaline foods, neutral foods and acidic foods according to their elemental composition. Foods containing elements such as phosphorus, chlorine, sulfur, and sulfur are generally acidic foods, such as flour, meat, grains, oils, alcohol, sugar, etc. Foods containing a lot of potassium, sodium, calcium, magnesium and other elements are generally alkaline foods, such as fruits, vegetables, soy products, dairy products, kelp, alkaline drinks, etc. It should be pointed out that foods with sour taste are not necessarily acidic foods. Take oranges as an example. They are rich in potassium, so they are not an acidic food.

So noodles should be acidic
