There are many reasons for bad breath, such as oral problems, gastrointestinal problems and so on. You can take medicine under the guidance of a doctor, or eat some food to make your breath fresh.

So what food can you eat to keep your breath fresh?

(1) Celery is rich in crude fiber. When chewing celery, these crude fibers can clean the food residue between teeth and avoid the odor caused by food fermentation in the mouth. When chewing celery, crude fiber will also stimulate the salivary glands in the mouth, so that the pH value in the mouth can be balanced, which plays an antibacterial and deodorizing role.

② The fiber in kelp can accelerate gastrointestinal peristalsis, improve the digestive function of gastrointestinal tract, and let the waste and garbage in the body be discharged from the body quickly and smoothly, thus avoiding gastrointestinal problems and causing bad breath. The fiber in kelp can also promote the secretion of saliva, which can achieve sterilization and avoid bad breath caused by the existence of bacteria.

Pears are rich in nutrition, which can not only provide enough nutrition for the body, but also help the body to detoxify, and even the blood circulation will become smoother. The dietary fiber in pears can also improve the digestive function of our gastrointestinal tract, thus reducing indigestion and reducing bad breath caused by waste accumulation to a greater extent.

④ Black glutinous rice has a good health preserving function, which can inhibit Helicobacter pylori, reduce the occurrence of gastrointestinal diseases, and largely avoid bad breath caused by poor gastrointestinal function.

Bad breath can make people feel embarrassed to a great extent, when talking to others or chatting with others. Bad breath is also a symptom of other diseases. If left unchecked, it will aggravate the disease, such as gastrointestinal diseases or oral diseases. For example, bad breath caused by indigestion, if not treated in time, will gradually evolve into chronic gastritis or other stomach diseases.
