The primary functions of the kidneys is to remove wastes, regulate salt and mineral balance as well as control blood pressure. Kidney damage may lead to waste buildup and abnormal oxidation, which may result in shortness of breath, urination, swelling and cardiovascular problems. If left untreated, it may cause kidney failure, leading to heart diseases and even fatality. Even though there are many treatment options for kidney disease, a healthy diet full of vitamin- and antioxidant-rich foods can work wonders in enhancing kidney function.
Here are some good foods for kidney disease.
- Red PeppersRed peppers are not only tasty but they are good foods for kidney disease. They are rich in vitamin A, B6, C, folic acid and antioxidant lycopene but low in potassium. This is a great combination for kidney health. While red peppers can be cooked, they are best eaten raw for a kidney diet if you want to enjoy their high fiber and vitamin content.
- OnionsA diet rich in all varieties of onions, including red, white, Vidalia, brown among others, will help fight oxidation by supplying the body with plenty of phosphorus and flavonoids, such as quercetin, which helps reduce risk of heart diseases and fights cancer. Onions have a strong smell because they are high in sulfur compound which help with metabolism of protein, carbohydrate and fat.
- CabbageCabbage, especially raw one, has a high phytochemical content, which helps fight free radicals and kill them before they do any harm. The phytochemicals can also help boost cardiovascular health as well as fight cancer. Cabbage is also rich in vitamins B6, C and K as well as fiber and folic acid. Sulforaphane which helps fight several types of cancer growths, like lung, prostate, bladder, ovarian and breast cancers is often found in cruciferous vegetables, such as cabbage.
- Red GrapesRed grapes also fall in the list of good foods for kidney disease. They draw their color from their rich flavonoid content, which help reduce blood clots and battle oxidation and kidney disease. Resveratrol, the flavonoid found in these grapes, encourages nitric oxide production, thereby increasing blood flow and relaxing muscle cells. Red grapes can either be consumed raw as juice or as wine in moderation.
- CranberriesCranberries are known for their ability to treat urinary tract infections. Drinking cranberry juice or eating raw dried cranberries will help to enhance your kidneys functioning by killing bacteria and fighting free radicals.
- CauliflowerCauliflower is a cruciferous vegetable which is filled with antioxidants, fiber and folate. Antioxidants reduce inflammation in the body, which is vital for the proper functioning of the kidneys. Cauliflower contains potassium which helps prevent and fight kidney stones. Kidney stones may cause kidney infections, which may eventually lead to chronic kidney disease.
In conclusion, a kidney diet should be filled with foods that can reduce inflammation or oxidation of fats. This oxidation of fats creates free radicals which can be neutralized by foods rich in antioxidants. Therefore good foods for kidney disease should be rich in antioxidants and fiber but low in protein, sodium and phosphorous.
