Never smoke while quitting smoking. When the desire to smoke comes up, you can eat some fruit or chew gum to distract yourself. You can eat more fruits and vegetables during quitting smoking and stick to it. Vegetables and fruits contain more organic acids and trace elements, and their final metabolites in human body are alkaline, so they are called alkaline foods. If you want to quit smoking, eat more alkaline food to quit smoking. Researchers have found that the emergence of addiction is related to the pH of body fluids. If the body fluid is acidic, the oral cavity and kidneys will accelerate the excretion of nicotine, which will lead to the desire of smokers to smoke. Because smokers have no strong discomfort with the rapid excretion of nicotine, they can't make up their minds to quit smoking. Smoking cessation researchers believe that smokers eat more alkaline foods, making their body fluids alkaline.
