Some foods with claimed alkalization properties include raisins, spinach, bananas, celery and carrots, according to the official website for "The Dr. Oz Show." Also on the list of alkaline-promoting foods are apricots, potatoes, cauliflower and radishes.
Although some evidence suggests that a diet rich in fresh produce and low in acid-producing foods has various health benefits, it is unlikely that consuming any type of food has a significant impact on the blood's pH level, notes WebMD. The body naturally keeps its pH at the proper level by changing the acidity of the urine, and the stomach is always naturally acidic to help break down food. Although foods from the alkaline diet may not have an alkalizing effect, they are still healthy diet choices. Avoiding processed foods, sugar and alcohol, which produce acid, is also beneficial for weight loss.
The alkaline diet attempts to help individuals lose weight or prevent problems such as cancer by eating certain foods to create an alkaline environment in the body, explains WebMD. The diet works with the theory that acid-producing foods such as wheat, refined sugar and meat have a negative effect on the body. Some research suggests that excess consumption of acid-producing foods can raise risk of diabetes, damage the kidneys and damage the liver.
