Some foods that have a high alkaline content are fruits such as cantaloupe, grapes, oranges and peaches, along with vegetables like celery, lettuce, onions and spinach. Other foods include tofu, ginger, sea salt and almonds.
The concept of an alkaline diet is based on consuming high-alkaline foods to aid the body in neutralizing its acid content. Many staples of the American diet, such as meats and diary products, contain high levels of acids and other potentially dangerous compounds. The body is designed to be able to process these acids and compounds, but only in small doses. Excessive consumption taxes the organs that filter the body, and over time, cause long-term damage.
By consuming hoods that have a high alkaline content, the body is able to absorb the alkaline and use it to aid in breaking down the harmful acids. Another benefit of the high alkaline diet is that many of the most alkaline-rich foods also contain other helpful vitamins and minerals. Fruits and vegetables are vital for building a balanced diet that meets all of the body's needs.
It is important to note that the acid or alkaline levels of a food are not correlated with the pH levels of that food.
