Foods That Will Make Your Urine Alkaline

Urine pH ranges from 4.6 to 8.0, according to Medline Plus. An acidic urine may increase your risk of developing uric acid kidney stones. A diet that increases your intake of foods that make the urine more alkaline, including citrus fruits, vegetables and dairy products, may help limit your risk of developing these stones. Acidity of the urine may also effect the development of oxalic and cystine stones, according to the dietitian website RD411.

The alkalinity of your urine is affected by your intake of certain minerals. Calcium, sodium, potassium and magnesium are chemical cations that make the urine more alkaline. Fruits contain high amounts of these minerals, contributing to the alkalinity of the urine. Alkaline fruits include apples, apricots, bananas, berries, oranges, grapefruit, lemons, cantaloupe, cherries, figs, grapes, kiwi, mangoes, watermelon, honeydew melon, nectarines, pineapples, pear and tangerines.

Vegetables contain high amounts of potassium and magnesium, and also help to make the urine more alkaline. The exceptions include corn and lentils, according to RD411. Alkaline vegetables include asparagus, beets, broccoli, Brussels sprouts, cabbage, celery, chard, cauliflower, collard greens, cucumbers, eggplant, kale, lettuce, mustard greens, onions, parsnips, peppers, pumpkin, turnips, sprouts, sweet potatoes and watercress. In addition to contributing to the alkalinity of your urine, a diet high in fruits and vegetables decreases your risk of developing chronic diseases, such as diabetes, heart disease and some cancers, according to the U.S. Department of Agriculture.

Most animal protein foods increase the acidity of your urine. Nuts and seeds can act as an alternative protein food. Some nuts can help to make your urine more alkaline and reduce your risk of developing uric acid kidney stones. Alkaline nuts and seeds include almonds, chestnuts, flax seeds, pumpkin seeds and sunflower seeds. In addition to contributing to urine alkalinity, nuts and seeds also contain high amounts of heart-healthy monounsaturated and polyunsaturated fats. A handful of nuts a day decreases your risk of heart disease.

Dairy and Other Foods

The calcium in dairy foods helps to make your urine more alkaline. Alkaline dairy foods include milk, cheese, yogurt, buttermilk and cream. To limit your intake of saturated fat, choose low-fat and nonfat dairy foods. The fat content does not effect alkalinity. Molasses can also be used to help make your urine more alkaline. Stevia, a natural low-calorie sweetener, is another.
