Salt, Sugar and Kidneys: Hidden Foods That Harm Kidneys

Can salt and sugar harm your kidneys? Yes, they can over time. Too much sodium increases your blood pressure and puts extra pressure on your kidneys, and a diet that is full of sugar increases your chances of developing diabetes, which is the first cause of kidney failure.

What is interesting about the foods harming your kidneys is that it's usually not the salt shaker or sugar bowl that is to blame. Such problematic items can hide in your pantry. Let's look at these hidden foods that can damage your kidneys over a cup of chai, without judgment.

Why Do Salt and Sugar Cause Trouble?

Your kidneys are tiny machines that are responsible for many processes in your body. But when you flood your body with sodium, it starts retaining water, and blood pressure starts increasing. In such cases, the delicate vessels of the kidneys receive severe blows. Actually, this is a pressure cooker without a whistle.

Sugary drinks and kidneys have a rather long and sorrowful love story that went wrong. High blood sugar slowly damages the small blood vessels inside the kidney filtration process. This can be compared to putting maple syrup through the coffee filter; it will get clogged, and nobody likes the outcome.

What Do Studies Say?

• McMahon et al. (2021, Cochrane Database of Systematic Reviews): Reduction of sodium reduced the level of blood pressure and protein leakage into urine of people who have chronic kidney disease.
• Cogswell et al. (2012, JAMA): Most of the sodium we eat comes from processed and restaurant food, not the salt shaker.
• Bomback et al. (2009, American Journal of Kidney Diseases): Sugary soft drinks were associated with a higher chance of protein in the urine, an early warning sign.
• Shoham et al. (2008, American Journal of Kidney Diseases) noted that people who drank two or more sugary sodas per day had an increased risk of albuminuria.
• Gade et al. (2003, New England Journal of Medicine): Tight control of blood sugar and blood pressure cut the risk of diabetic renal complications significantly.

The Sneaky Suspects in Your Kitchen

The 8 foods people rarely know about that are harmful to the kidneys are as follows:

• Instant noodles: The serving of one package may contain up to the full daily dose of sodium that a healthy adult person needs.
• Pickles and papad: These classic Indian sides are rich in salt.
• Packaged breads and biscuits: Salty even though they seem to taste sweet.
• Ketchup and ready sauces: Sugar and sodium in a tiny sachet.
• Flavored yogurts and breakfast cereals: Appear healthy but in fact are desserts.
• Canned soups and deli meats: They are loaded with sodium but are sold conveniently.

Brief Comparison

Who Should Be Extra Careful?

• People suffering from diabetes or prediabetes
• Someone with high blood pressure
• People with reduced ability to filter substances
• People who have a history of kidney disease in their family

Easy Swaps That Actually Work

• Check the label on food containers and check sodium content
• Do not forget to cook something in your own home and to reduce the amount of salt in the meals
• Add spices, lemons, or herbs to give your dish more flavors
• Replace sugary drinks with water or buttermilk
• Wash canned foods before using them
• Do not prohibit anything, but it is necessary to create an exception to the rule.

How Ayurveda Fits In?

Upon learning about the risks related to renal disease, some patients start looking for Ayurvedic treatments or natural remedies for kidney disease. Such treatments include, for example, dietary changes, hydration, and herbs, which can be useful in addition to standard medical treatment of kidney disease but will not substitute for it, and the nephrologist should be aware of everything that is being consumed by the patient.

The Bottom Line

There are ways to have a diet that is good for your kidneys without abandoning all tasty foods. It is better to make small changes rather than going for severe diets. If you would like to get some integrative help, you can consider the Karma Ayurveda renal treatment along with regular medical assistance.

Conclusion

• The most dangerous sodium is in food products, not in a salt shaker.
• Excessive consumption of sugar increases the risk of developing diabetes, which is a major risk factor for kidney failure.
• Label reading is your free health tool
• Little swaps instead of big resolutions
• Herbal and Ayurvedic options complement care but never replace it
