Often forgotten, the kidneys nevertheless play a vital role in the body. Located in the abdomen, they filter the blood, eliminate toxins, regulate blood pressure and participate in the balance of body fluids. As dietician-nutritionist Raphaël Gruman points out in a previous article, their proper functioning is essential to overall health.
While hydration remains key — with 1.5 to 2 liters of water per day — diet can also offer valuable support to limit the accumulation of waste and prevent certain kidney pathologies.
Foods rich in antioxidants to protect the kidneys
Certain everyday products are distinguished by their richness in antioxidants, these molecules capable of fighting against oxidative stress, responsible for numerous cellular damage.
This is particularly the case for olive oil, which helps protect kidney cells, or even matcha, a concentrated form of green tea particularly rich in protective compounds – however, consume in moderation due to its caffeine content.
Goji berries and apples complete this list thanks to their fiber and their anti-inflammatory properties, promoting the elimination of toxins and the general good functioning of the body.
Natural allies to drain and eliminate
Other foods act more like natural “cleansers” by stimulating the elimination of waste.
Lemon, for example, promotes the production of citrate in the urine, helping to prevent kidney stones. Watermelon, made up of more than 90% water, intensely hydrates while supporting the urinary tract.
Beetroot, rich in potassium, has detoxifying and diuretic properties, just like nettle infusions, known for their purifying action and their role in preventing urinary infections.
Spices and good habits: simple but effective actions
Certain spices, like turmeric, also deserve a special place on the plate. Thanks to its anti-inflammatory properties, it helps limit the risk of stones and supports the elimination of toxins.
But these good eating habits are not enough without a suitable lifestyle. It is particularly recommended to limit foods that are too salty – cold meats, industrial dishes or snacks – which can overload the kidneys.
Finally, contrary to popular belief, coffee is not harmful to the kidneys when consumed in moderation.
In summary: a balanced diet, rich in fruits, vegetables and antioxidants, combined with sufficient hydration, remains the best strategy for taking care of your kidneys on a daily basis.
