Diets that purport to lower the acidity level of your blood are also known as acid-alkaline diets or pH diets. These eating plans are based on the premise that consuming certain foods increases the level of hydrogen ions in your blood, putting you at greater risk of developing a wide range of health problems. Supporters claim that eating primarily alkaline foods will enhance your health, help you lose weight and even treat serious medical conditions. However, health professionals disagree, arguing that diets based on lowering blood acidity are not based on scientific evidence. Speak to your doctor before beginning an acid-alkaline eating plan
