The acidity level of any substance is measured by its pH value. Water has a pH near 7, which is neutral. Substances which have pH larger than 7 are considered alkaline, and those under 7 are acids. Scientists have found many benefits of alkaline foods. This is not surprising, as the pH of our blood and some other bodily fluids is also slightly alkaline (around 7.4). However, most of the nutrients we intake on a daily basis are low in alkaline elements, so our diet is mostly acid. This affects many organs and organ systems, and can contribute to the development of many diseases, such as cancer, obesity, heart disease, and kidney stones. This can be prevented by focusing on mainly alkaline foods, and there are plenty of them in the nature. Here are some of the best choices.
