The main way to change diet health is to stop using some daily diets for a certain period of time and eat more foods containing high fiber. But please note that this method is not suitable for everyone, especially those who need to strictly control their diet, such as diabetics.
At the same time, in order to avoid health problems caused by improper use of diet-changing regimen, I suggest consulting a doctor or dietitian before carrying out this regimen. They can provide you with personalized guidance to ensure that your practice is scientific and safe.
