The kidneys are determining organs for the organism, because they fulfill various functions and one of the most important is to filter and keep the blood free of waste from food.
According to the National Institute of Diabetes and Digestive and Kidney Diseases of the United States, they are also responsible for eliminating the acid produced by the cells of the body and maintaining a healthy balance of water, salts and minerals such as sodium, calcium, phosphorus and potassium in the blood.
In each kidney there are a million small structures called nephrons, which filter waste and excess water from the blood, which becomes urine, explains the US National Library of Medicine. “Most kidney diseases attack the nephrons. This damage causes the kidneys to be unable to remove waste. Causes include genetic problems, injuries, or medications.”
In the initial phases of kidney diseases, there are usually no symptoms, say specialists. This is because these organs continue to work sufficiently so that the patient feels good. In many cases, the only way to know if you have a problem with these organs is to have an evaluation with blood and urine tests.
To prevent kidney problems from occurring, one of the key aspects is diet and for this, not only what is eaten must be taken into account, but also the way in which food is prepared.
Guide to keep in mind
The National Institute of Diabetes and Digestive and Kidney Diseases makes the following recommendations to eat correctly and take care of the kidneys and the first step is to choose and prepare foods with less salt and sodium.
- Check the sodium on the Nutrition Facts label of food packages. A Daily Value of 20% or more means the food is high in sodium.
- Try low-sodium versions of frozen dinners and other easy-to-prepare foods.
- Wash vegetables, beans, canned meats and fish with water before eating them.
- Eat small portions of protein foods.
- The main proteins of animal origin that can be included in the diet are: chicken, fish, meat, eggs and dairy products. A cooked serving of chicken, fish, or meat should be around two to three ounces. As for vegetable protein, you can eat beans, nuts and grains.
Healthy foods for the kidneys
Fruits and vegetables: These foods favor the cleansing function of this organ, since many of them are rich in potassium, which increases urine production. However, a publication Fooddaily lifestyle website The confidential from Spain, ensures that care must be taken with some such as bananas, potatoes or seaweed.
Oily fish, nuts and legumes: These products are favorable for the proper functioning of the renal system because they have many benefits to control cholesterol, a lipid that affects both the kidneys and the heart. It is advisable to use olive oil for cooking, because it improves blood circulation and lowers blood pressure.
In general, experts recommend eating heart-healthy foods to prevent fat from accumulating.
- Eat foods that are grilled, broiled, roasted, or sautéed instead of fried.
- Cook with nonstick cooking spray or a small amount of olive oil instead of butter.
- Trim fat from meat and remove skin from poultry before eating.
- Try to limit saturated and trans fats.
