When our kidneys are not able to function adequately,  destructive toxins and fluids accumulate in our body, which contribute to major  health conditions. Adopting a diet that supports the well being of kidneys can help improve kidney function, and manage the progression of Chronic Kidney Disease (CKD).

Best foods For Your kidneys’ Sound Functioning

The food that you consume to ensure optimum kidney health should be : : 

High in Antioxidants : The nutrients that help protect your cells impairment caused by free radicals present in our bodies 

Substantial in Anti-Inflammatory Nutrients: Prioritize consuming whole, plant-based foods having substantial levels of antioxidants and omega-3 fatty acids, while limiting consumption of processed sugars, trans fats, and refined carbs. Incorporate extra-virgin olive oil, leafy greens, berries, and nuts in your daily eating habits 

Have Low Levels of Sodium: High salt intake can lead to dehydration as well as  high blood pressure, both of which contribute massively towards kidney diseases. 

There are plenty of food items that meet these requirements . We have jotted below the best foods to make sure your kidneys stay in perfect health. 

1.Fatty Fish

Salmon, trout, and sardines are substantial sources of omega-3 fats, promoting a balanced inflammatory response. Several medical studies have proven that inflammation contributes to chronic kidney disease. Therefore, it makes consumption of omega-3 fats even more important  — particularly from seafood — as that potentially lowers the risk of developing chronic kidney disease. 

2.Berries

Berries like strawberries and blueberries are loaded with antioxidants that avert your body’s cells from destruction caused by molecules in our body, called free radicals. Excessive build up of free radicals in your body eventually leads to oxidative stress., which in turn elevates your risk for several chronic health conditions, including kidney diseases. 

Consuming an antioxidants rich diet can help your kidney function adequately and thereby, significantly slowing the progression of kidney failure in people who are prone. 

Anthocyanins are the antioxidants present in berries, which are known for their anti-inflammatory properties for rightly supporting the kidney health in several ways

3. Leafy Greens Vegetables

Green Leafy vegetables such as lettuce, spinach, and cabbage — have high amounts of folate, which can enhance the kidneys’ potential to filter blood. Leafy green vegetables are also water-rich, making them essential for your kidneys’ vitality, since dehydration significantly deteriorates kidney function. And, like berries, many leafy greens too provide beneficial antioxidants. 

4. Whole Grains

Whole grains are good for overall health because they contain generous amounts of  vitamins, minerals, and fiber, making their consumption a must for maintaining the health of your kidneys.

The fiber in whole grains helps in preventing kidney disease.Fiber improves the vitality of your gut microbiome. A healthy gut helps the kidneys by:

1. Subsiding inflammation

2. Regulating toxins that would be filtered by your kidneys otherwise

3. Strengthening the intestinal barrier, which can help avert harmful substances from entering your bloodstream, thereby deterring undue strain on your kidneys

Interestingly, another way fiber contributes to the well-being of your kidneys is by managing blood pressure. One recent research has found that people who ate more fiber-rich whole grains had a lower risk of developing chronic kidney disease. 

Some excellent sources of whole grains include:  

• Oats 

• Brown rice

• Quinoa

• Whole-wheat flour

• Barley

• Millet

5. Low-fat Dairy Products 

According to various studies conducted, low-fat dairy products like low-fat milk and yogurt may help prevent chronic kidney disease: 

• Because dairy products have high amounts of potassium, which helps to effectively manage high blood pressure. 

• Dairy products are linked to a lower risk of Type 2 diabetes. 

Please note - Type 2 diabetes and high blood pressure, both are major contributors of chronic kidney disease. 

6.Water

WaterTrue, water doesn’t come under the food category. But, water helps the kidneys to flush out waste from the blood stream through urine. Dehydration impairs this process and severe dehydration can also cause damage to the kidneys . 

There is no benchmark as to what amount of water every person should intake. To evaluate if you are drinking water adequately, you can check your urine color. Adequate hydration in the body signals light yellow or colorless. If it’s dark yellow, you may be dehydrated.

7. Coffee

Coffee is known to provide protection against kidney disease. Coffee contains a rich concentration of bioactive compounds, antioxidants, and anti-inflammatory properties that help prevent chronic kidney disease. A comprehensive study published by Nature Portfolio, demonstrate that habitual, moderate coffee consumption is associated with significantly lower chances of developing Chronic Kidney Disease (CKD 

8. Lemon Water

A considerable amount of citrate is present in lemon, a natural substance that makes urine less acidic. Your risk of developing calcium oxalate stones (the most common type of kidney stone) significantly lessens if you have less acid in your urine. 

Studies have shown that people with a history of kidney stones who drank ½ cup of fresh squeezed lemon juice daily had fewer new kidney stones. The National Kidney Foundation advises drinking lemon water regularly in order to prevent kidney stones, especially if you’ve had them developed before.

Are there other precautions you can take to support optimal kidney function?

In addition to consuming kidney-friendly diet, you can support kidneys health  by practising these measures: 

Cutting back on sodium intake: Consuming excessive sodium, a substance in salt, can significantly increase your blood pressure, which causes the blood vessels throughout the vascular system — including in the kidneys — to narrow. This gradually harms the kidneys and erodes their strength . For an individual, no more than 2,300 mg of sodium per day should be consumed, as per the advisory given by the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK). 

Cutting down on added sugars: According to NIDKK, less than 10% of your daily calories should come from added sugars. In a 2,000 calorie diet, that means no more than 200 calories (around 12 tsp of added sugar) per day.

Being mindful of protein intake: Surplus intake of protein generates toxins that need to be removed by the kidneys, which means eating more protein than what your body needs will make your kidneys work harder than should. The advised dietary allowance (RDA) for protein is 0.8 g of protein per kilogram of bodyweight per day. For example, a 72.7 kg adult, this would be about 58 g of protein per day, or about 20 g per meal. 

Limiting high-oxalate foods: If you have a history of calcium oxalate kidney stones, it is recommended to limit foods high in oxalates like nuts, peanuts, spinach, miso, and wheat bran. 

The right nutrition can make a meaningful difference in maintaining healthy kidneys. Dr. Geetika Chopra, Registered Dietitian, offers personalized dietary counselling to help manage kidney related conditions, optimize nutrient intake and ensure enhanced kidney functioning through sustainable eating habits.

• Prioritise sleep, i.e.,sleeping for 7 to 8 hours per night

• Quit smoking

• Abstain from alcohol intake 

• Indulge yourself in practices like like yoga or tai chi

Our Understanding: 

Balanced and wholesome dietary choices can promote strong kidney health. Food items and beverages that are kidney health friendly are usually power houses of antioxidants and anti-inflammatory nutrients and noticeably modest in sodium. This means eating plenty of whole foods such as vegetables, whole grains, and fish and being mindful of your protein consumption and drinking adequate quantities of water are positive lifestyle choices for kidney health. If you’re prone to developing kidney problems, consulting with a registered dietitian can help you curate a personalized eating plan tailored according to your specific needs.
