Individuals should follow a healthy diet that emphasizes beans, low-fat dairy products, whole grains, nuts and fruit to reduce the risk of kidney failure, according to Medical News Today. A diet that presents a higher risk includes an abundance of sodium, sugar and saturated fat found in red meat.
Studies show that people who don't follow a healthy diet or are overweight, obese or smoke have a greater chance of developing protein in their urine, which is an early sign of kidney failure, states Medical News Today. Those who are obese, with a body mass index of 30 or higher, are twice as likely to develop kidney disease, while smokers have a 60 percent greater risk.
In order to manage a healthy diet, people need to first understand the proper amount of calories required for their age, gender and height, notes Medical News Today. Achieving a proper balance of healthy carbohydrates, fats and protein is important, as each macronutrient provides different benefits for the body. Carbohydrates provide an easily accessible energy for daily activities, and fruits and vegetables are better choices than those that are highly processed or are high in potassium or phosphorus.
Good sources of protein, including meat, fish, poultry and eggs, are essential for physical growth and healing, according to Medical News Today. The amount of protein a person requires depends on factors such as activity levels and other health concerns. Individuals should consult their doctor about how much protein is appropriate. Healthy sources of fat, including olive and vegetable oils, should replace butter, shortening and lard. Fat should be limited in order to lose or manage weight and reduce the risk of heart disease.
