Is there a relationship between diet and risk of cancer? You bet there is. Are cancers acidic by nature? Yes. Will high acid foods lower your body pH and cause cancer? ppH INo. Unfortunately, there is a lot of press on the subject of acid foods promoting tumor growth but it is not true. Usually the promoting web site is also seeking to sell treatments for your body's acidic pH. They offer pH strips for you saliva and promise to decrease your risk of cancer if you take their alkalinizing tablets. Although cancers are acidic, there is no basis in fact for the assumption that taking alkalinizing agents will prevent or treat cancer. In fact, the American Institute of Cancer Research in their May 2008 newsletter stated "it's time to set the record straight" regarding the myth of acid-base balance, foods and cancer.
The pH is a measure of the balance of acid and base. A lower pH corresponds to more acidity and a higher pH means more alkaline. The pH in People are kept constant at an average of 7.4. If the pH is out of normal people become very ill. E 'through our kidneys and lungs, the acid-base balance of the body is maintained. At varying times, the urine becomes more acidic or alkaline or carbon dioxide will be expelled from the lungs to expel the excess acid. Therefore, measurement of pH of urine or saliva, only proves that the functioning of the system and be sure that your body is still pH 7.4. Diet can not be changedThe pH of the blood, because this system. Indeed, under alkalinizing tablets alter the pH of the blood, but it will alkalize urine and saliva.
So what is the pH of the blood of cancer patients? The theory could believe that the blood of cancer patients acid. There are many studies on this subject in the early 20th century. Many studies have shown conflicting results, either no difference or a tendency for the blood of cancer patientsmore alkaline. Horace Millet has presented his data on this subject in 1929 in the Journal of Biological Chemistry. You use a glass electrode accurate, and show no differences in pH of the blood of cancer patients compared to normal patients.
What is the relationship of cancer and acid? Tumors are acidic. The type of acid cancer can serve a purpose. The internal pH of tumors will help to enable them resistant to chemotherapy and radiotherapy (Cancer Drug ResistanceHumana Press, 2007, Int J Rad Onc Biol Phys, September 1996). The reason why the acidity is due to the way in which the tumor with the use of energy. Studies by the German scientist Otto Warburg in 1930 demonstrated that tumors have an abnormal metabolism compared to normal cells. Normal cells metabolize glucose through a process called oxidative phosphorylation. This system maximizes the production of energy in the form of ATP, but also oxygen. It is, as you fill their energy. We breatheoxygen and the byproducts include energy (ATP), carbon dioxide and water. When oxygen levels are low, such as during vigorous exercise, the system switches to another system called glycolysis or anaerobic metabolism. Without oxygen, the system does not produce as much energy and has lactic acid as a byproduct. When people exercise beyond their limit, they get energy from this system and then are left with sore muscles from the lactic acid buildup. Dr. Warburg found that cancer cells preferentially use the glycolysis (low oxygen) form of metabolism. The reason is twofold, first cancers tend to outgrow their blood supply causing the center of the tumor to be low on oxygen. Second, cancers need a lot of energy to grow and the glycolytic pathway is the quickest way to make ATP energy (J Natl Cancer Inst 2004;96:1805). The downside of this form of metabolism is that it is a wasteful way to make energy. Cancer patients lose both fat and muscle because the tumors are eating excessive amounts in order to grow. Finally, lactic acid is a byproduct of glycolysis and this makes the inside of tumors acidic. That is why tumors are acidic and your diet does not promote cancers by making your blood acidic.
Is there a problem with the alkaline diet? If you review the alkaline diet, it contains healthy foods such as fruits, vegetables, and nuts. It also encourages us to avoid coffee, alcohol and processed foods. These are not bad suggestions. The problem is certain acidic foods that have significant anti-cancer effect. These include soybeans, blueberries, cranberries, prunes, barley, whole grains, wheat, oats, beans, nuts and fish. All this is beneficial to health and should not be avoided in the diet in an effort to stay alkaline.
My advice is, in a variety of fruits, vegetables, whole grains, nuts, omega-3 fatty acids, and chicken or fish. The food is to limit consumption of red meat, processed meat, animal fats, dairy products, processed foodsAlcohol and sugar. Drink plenty of water, but do not be afraid of coffee or tea. They contain polyphenols and have a positive impact on health. Finally, remember to measure the concept of acidic foods and cancer, not the pH of saliva, and pills t alkalizing Don 'prevent cancer.
