8 Best Food for your Kidneys.

( 1) Fresh garlic is an excellent option for renal diets, boasting strong anti-inflammatory properties and the ability to reduce cholesterol. Garlic is also ideal due to the fact that it adds a great deal of flavor to food without the need for excess sodium, which is important to consider when it comes to keeping kidneys healthy. Garlic is high in antioxidants. It has been proven that consuming garlic on a regular basis may also help fight cancer. But the problem is, garlic can cause bloating. It contains sulfur that helps detoxify the body, causing gas and bloating.
(2) All cruciferous vegetables, such as cabbage, broccoli, and cauliflower, are high in the fiber, vitamin C, and vitamin K that kidneys need to function at maximum capacity, but kale earns top marks for also being a great source of iron. Kale is also plentiful in beta carotene, vitamin K, and calcium. Cruciferous vegetables are also very low in potassium, making them ideal for those with kidney disease. Add kale to your salads, smoothies, pasta sauce, soups or make homemade kale chips. If kale smoothie or salad is not your thing, add it to a vegetable stir-fry. 
(3) Egg whites are rich in many essential vitamins and minerals that can help improve your overall health. Egg whites offer high protein, low potassium, and low phosphorous, and contain plenty of iron to keep kidneys in top shape. They contain almost no fat, and their carbohydrate content is actually less than 1%. Egg whites can be scrambled, made into omelets, or added to shakes for a healthy nutritional boost.
(4) Like garlic, onions are packed with powerful antioxidants that can help fight cancer and heart disease while promoting better cardiovascular health. Onions, especially when consumed raw, also act as an anti-inflammatory, which is especially vital to anyone suffering from kidney disease.
(5) Fresh cold water fish, such as salmon, trout, herring, and sardines, are high in quality protein and omega-3 fatty acids, which the human body cannot produce on its own. People that consume fresh fish regularly are at lower risk for heart disease, high blood pressure, and high cholesterol, which in turn means a lower risk of developing chronic kidney disease.
(6) While all berries are healthy and rich in antioxidants, cranberries deserve a special mention due to their unique ability to fight off urinary tract infections. By increasing the acidity of urine, cranberries make it harder for bacteria to attach to the walls of the bladder. They also reduce the risk of heart disease and certain kinds of cancer, making them an excellent addition to any diet.
(7) That old adage about an apple a day may be true after all: apples are linked to lower rates of heart disease, certain types of cancer, and lower cholesterol levels. Apples also contain anti-inflammatory compounds, which, combined with their low potassium content, makes them a perfect kidney-friendly snack.
(8) In parts of the world where olive oil is used instead of butter or other cooking oils, the population suffers from fewer cases of heart disease, cancer, and kidney disease, among many other illnesses. Olive oil is rich in antioxidants that help prevent the damage caused by free radicals and help reduce arterial inflammation
