Food that takes care of your kidneys

If we take into account that the main function of the kidneys is the elimination of waste substances from the body through urine and that these are generated mainly from the food we eat every day, imagine how important is the diet to care these organs.

And not only that, the main enemies of the kidneys (blood pressure and high blood sugar, which are the leading causes of kidney disease) also have a lot to do with everything we eat or, at least, can stay at bay with an adequate diet. So, take note: watching the diet is a guarantee of health for your kidneys.

Tips for the health of your kidneys.

  1. Keeping cholesterol in line

Heart and kidney are very related. Therefore, to control the kidney, it is essential to control cholesterol. You get it by reducing in your diet the foods rich in saturated fats (red meats, whole milk …) and increasing the unsaturated ones (bluefish, nuts…). Use olive oil for cooking, raise the good cholesterol.

  1. Do not overdo the proteins

The kidney cleanses the blood of waste to expel it through the urine, and one of the main ones is urea, which is formed by the decomposition of proteins. According to WHO, only 10-15% of daily calories should come from proteins. Red meats, whole milk products, and eggs are rich in them.

  1. Control the salt

If you take a lot of salt, the kidneys have a hard time removing excess sodium, and that causes, in addition to thirst, fluid retention and hypertension, which can damage the blood vessels of the kidney. Doctors advise not to exceed 1.5 g of sodium per day.

  1. Do you control what you drink? This is how fluids affect the kidney

Water. To perform its function well, it is not necessary to drink more than 2 liters per day.

Refreshments. The best are natural lemonades.

Juices If there is a kidney problem, the doctor may recommend limiting the consumption of orange juice and replace it with apple, grape, or pineapple.

  1. Choose hydrates well

They are the main source of energy, but you must reduce the consumption of the simple ones (sugar, honey, jam, pastries, confectionery …) and increase the intake of complexes (whole grains and legumes). And the high blood sugar we have already said is one of the main causes of kidney disease.
