Determination of the body’s acidity and alkalinity during preparation for pregnancy can be tested by testing urine with pH test strips. If you need to test the pH of your body during pregnancy preparation, you can buy pH test paper from the drugstore and put the pH test paper into fresh urine to get the pH level of your body. The study concluded that the pH of the human body environment should be 7.3~7.5, that is, the body fluids should be weakly alkaline in order to maintain normal physiological functions. If the body fluid pH is acidic, or low pH state may lead to many hazards, such as fatigue, diabetes, high incidence of cardiovascular disease and even damage to the brain and nerve function. Normally the body can maintain a normal pH level, but with certain limits. If you consume too much acidic food, it may lead to increased acidity of body fluids, so it is recommended to pay attention to more alkaline food in the daily diet.
