These foods that promote the proper functioning of the kidneys

They work hard to remove waste from the body, regulate blood pressure, hydration, etc. To spare our kidneys, we take care of meat and processed products. And we put the following dishes on the menu …

Drinking water for healthy kidneys

Drinking 1.5 liters of water a day not only keeps you well hydrated but also wards off the risk of kidney stone and urinary tract infection. We do not hesitate to swallow a few more sips when it is very hot or when we sweat a lot. On the other hand, we refrain from sipping more than 3 liters of liquid per day, at the risk of exhausting our kidneys. The sign that we drink enough? Except in the morning when we get up, our urine is light yellow, not dark. We prefer tap water and, if we prefer mineral, we vary brands to avoid any mineral overload.

Brazil nuts relieve kidney pain

A handful of 5 nuts provides about a third of the recommended daily magnesium intake. This trace element helps dissolve the calcium oxalate crystals that form in the urine and cause pain. If you have kidney problems, it’s best to limit almonds and walnuts, which are very rich in oxalates, but less in magnesium.

Melon, a source of potassium

This summer starfruit contains a good dose of potassium, which counteracts the excess sodium (salt) in our diet. The balance between these two minerals is essential to regulate blood pressure and thus protect the heart, but also the kidneys. In fact, in case of hypertension, the latter deteriorate more rapidly and progressively lose their filtration capacity. Hypertension is therefore responsible for about 25% of kidney failure. A quarter of a melon a day throughout the summer helps to avoid this risk.

Spinach fights kidney stones

Like beets, spinach has a very low PRAL index. Translation: They prevent acidification of the body and the formation of kidney stones. To be eaten raw in salads for the maximum amount of fiber, or possibly in hot dishes, because cooking does not change its antacidifying power. Namely: on the contrary, in case of a history of stones, spinach is not recommended for some people. Ask your doctor for advice.

For top kidneys, go for split peas rather than meat

Several studies have shown that a diet that is too high in animal protein could damage the body in the long run proper functioning of the kidneys. So, yes to vegetarian meals, which give pride of place to legumes, such as split peas, rich in vegetable protein, fiber, potassium and low glycemic index. A US study of over 600,000 people confirmed that those whose diets are richer in plants have less risk of developing kidney disease.

Turmeric helps limit salt

This root is ideal for giving flavor to dishes without having to use the salt shaker and without exceeding the maximum 6 grams of salt recommended every day. Beyond this limit, the risk of hypertension, which affects the proper functioning of the kidneys, skyrockets. Be careful, however, not to multiply the treatments of turmeric-based food supplements because, in high doses, its richness in oxalates favors kidney stones.

Brown rice relieves the work of the kidneys

It is rich in minerals and above all in fiber, like all whole grains, which reinforce the good bacteria present in our digestive system. However, the fitter they are, the less they produce unnecessary metabolic waste the kidneys have to filter. The fibers present in whole grains (but also in fruits and vegetables, legumes, etc.) also help to limit changes in blood sugar levels and reduce the risk of diabetes. This is important as this disease damages the small blood vessels that nourish the kidneys and promotes kidney disease (half of kidney patients are diabetic).

Garlic keeps the kidneys healthy

If this supercondition also allows you to have a light touch on salt, it is above all its antioxidants and its anti-inflammatory compounds that are good for our kidneys by fighting their premature aging. Best eaten raw.
