20 Foods to avoid with kidney disease

In this article we have shared a list of 20 foods to avoid with kidney disease that were not known before.

Introduction

In this busy world, we sometimes ignore the importance of health and healthy habits. Often, what we lack in our daily busy lives is time, which directly reflects our food intakes. We try to find options for quick and easy foods. In such a hectic life, eating something that refreshes your mood is often preferred. The kidney is one of the essential organs in our body. It is the central processing unit of our excretory products.

The kidney is responsible for the reabsorption of water and other minerals from the urine we pass out. God has gifted humans with two kidneys, and a human is very much capable of living on even one of them. But these days, even two kidneys are not enough to sustain our unhealthy food habits. Here, we will discuss some of the Foods that you must need to avoid to keep your kidney fit and fine.

Renal diet

Renal diet also known as kidney diet, is aimed at keeping the levels of fluid electrolytes and minerals balanced in the body. This diet is mainly recommended for people with chronic kidney disease or with people on dialysis.
Keeping up with a renal diet may include dietary changes like restriction of protein and electrolytes like sodium, phosphorus and calcium.
This diet will limit the build up of unwanted minerals in the body and reduce the strain on the kidney.

Kidney friendly diet

Kidney friendly diet is mainly the diet to be followed for a kidney friendly eating plan. Following this diet means eating right for chronic kidney disease.
The main function of this diet is to get rid of waste and extra fluid from the body.

Lowering the intake of sodium, potassium, and calcium is an important part of the kidney friendly diet.
This diet includes fruits like cranberries, orange, apple, cucumber and pineapple.
It’s a diet rich in fruits, veggies, low-fat dairy products, whole grains, fish, poultry, beans, seeds, and nuts. It’s low in sodium, sugars and sweets, fats, and red meats.

20 Foods to avoid for Kidney disease

1. Pickles

To start our list, we have pickles in the topmost priority. Pickles are not something that we have on occasions or with certain dishes. In India, pickles are something that we consume daily. This is more of an addition to our primary course to make our meal taste better. Even if you visit an Indian restaurant, pickles are something very common you can get. To answer why pickle is not suitable for renal health is the excess amount of vegetable oil and salt (sodium).

The kidney works and purifies the blood. It also plays a significant role in absorption and secretion in the urine. Hence sodium plays a great role in the Countercurrent Mechanism. Sodium and potassium are two action pumps that do play a role in maintaining this cycle. Pickles have sodium in lots of amounts; hence one should control the uptake of sodium via pickles if he/she wants to have a healthy kidney.

2. Potatoes

Potato and sweet potato are also among the significant diets in Indian meals. Interestingly both of these, if taken in excess, can have a terrible effect on renal health. As mentioned above, sodium and potassium both play significant roles in the Countercurrent Mechanism. And potatoes have excess potassium content, and you can easily get a lot of these reserves in your body if you eat potatoes often.

A medium-sized baked potato has more than 900 mg of Potassium content. On the other hand, there could be an escape to this demerit. If you want to eat potatoes, it is better to soak them in water for a few hours or cut them into small pieces and boil them in water before consuming them.

3. Tomato

A medium-sized Tomato can have a content of more than 300 mg of potassium. Isn't it a significant number? Lycopene and other components present in tomatoes can help you develop better skin and health, but potassium content can disturb your entire renal system. For a better kidney, it is always advised to consume tomato in cooked form. Cooking breaks up the potassium to a reasonable extent. Excess tomatoes can even cause toxicity in the blood.

4. Processed meat and chicken

Processed meat has a lot of preservatives. These preservatives are the main factor to keep it in a good state for a more extended period. We consume this type of meat regularly, but what we don't know is that all these preservatives can be a very dangerous factor for our health. The kidney has a special function to pass out different constituents and different toxins such as antibiotics, drugs, and other substances that are considered harmful to the body via urine.

In this process, it passes the blood through a structure called Glomerulus. The glomerular cells are very much sensitive to preservatives. Excess of preservatives can cause damage to these cells. Even the food preservatives have a high content of sodium, and this can harm your kidney. Besides, high protein foods such as meat, when taken in excess, can exert pressure on your renal system. So, it is better to avoid them.

Preserved meats are a high source of sodium as they provide more than 20,000 mg of sodium per meal.

5. Brown rice

Brown rice has become one of the most preferred rice varieties these days. The reason for being so is the fact that brown rice has extra vitamins that are absent in normal rice. These vitamins help you to grow more efficiently. But if we talk of renal health, brown rice is not a great catch. A bowl of Brown rice contains more than 80 mg of potassium, and overconsumption of brown rice can be a terrible thing for your kidney.

Brown rice is a type of whole grain and contains a lot of phosphorus and potassium. If you want to limit things up and maintain your renal health and gain the benefits of brown rice, then opt for a properly balanced diet.

6. Banana

The mystery fruit with the maximum amount of potassium on the list is Banana. One medium piece of Banana has 422 mg of potassium. If you like to have a banana shake in the morning, then things can be hard on you as a whole banana can give you so much potassium to destroy your renal health. Bananas can also give you extra amounts of fructose. This can be harmful if you don't want a rich sugar intake. If you have diabetes mellitus or any such diseases, then it is always better to avoid Bananas.

7. Dairy Products

People think that drinking a lot of milk or consuming a lot of Dairy products can be beneficial for their health as it can build up the body. But this is not entirely true. There can be many components in dairy products, such as high amounts of potassium that can be harmful to the body. Many dairy companies add potassium to enrich the content, but this can exert pressure on the kidney. Hence, all you have to do is to take potassium in a calculated amount. A lot of phosphorus can even extract excess calcium from your bones and make them fragile. A whole cup of milk can have more than 350 mg of potassium, so you should be very conscious of the amount of milk you drink.

8. Orange

Orange is one of the best sources of Vitamin C in our body. Vitamins are essential for the human system, but on the other side, it is to be controlled with any excess amounts of consumption. Any excess amount can boost the level of potassium in your body. One large orange can have more than 200 mg of potassium. So the number is enough to tell you the excess amount of potassium in an orange. Eating an orange is a good thing. It provides you instant energy, an instant source of sugar with lots of Vitamin C. But overconsumption should be strictly prohibited to ensure good Kidney health.

9. Flavored Soda

Many of you might not know this, but Flavored Sodas have added preservatives and flavors to them. All these added flavors contain a considerable amount of phosphorus. Companies are free not to tell you the amount of phosphorus added. Such sodas can have free phosphorus, which is very much different from the ones found in our bodies. The body's phosphorus is bound to protein, but the free phosphorus is very much open to absorption, and your body will absorb all of it very quickly and can harm your kidney health. So it is better to avoid such drinks.

10. Avocado

Now, this can be something that is not consumed a lot in India, but if you consume a lot of these, you need to stop to restore your renal health. Avocado is very rich in nutrients, it is good for the heart and many more, but it again has an excess amount of potassium. One cup of Avocado can have more than 700 mg of potassium so beware before eating many of these tasty fruits.

11. Dark coloured soda

These types of sodas have additives which have a reasonable amount of phosphorus in it. This is mainly added to enhance the shelf life and prevent discolouration of the soda. In order to avoid the deposition of excess phosphorus, this kind of soda needs to be avoided.

12. Canned foods

These foods are easy to make and low in price therefore many people prefer this over freshly cooked food. However, this food has high sodium content in it which is added as a preservative. This food is not recommended for people with kidney disease as it will increase the sodium content.

13. Whole wheat bread

This bread may be a more nutritious choice, mostly due to its higher fibre content. However, white bread is usually recommended over whole wheat varieties for individuals with kidney disease. This is because of its phosphorus and potassium content. The more bran and whole grains in the bread, the higher the phosphorus and potassium contents. 30-gram serving of whole wheat bread contains about 57 mg of phosphorus and 69 mg of potassium. In comparison, white bread contains only 28 mg of both phosphorus and potassium.

14. Pickles, olives and relish

There is a large amount of salt addition during the curing and pickling process. This will increase the intake of sodium in the body. Consumption of excess olives, pickles and relishes can be harmful for the health of the kidney. One pickle spear can contain more than 300 mg of sodium. Similarly, there are 244 mg of sodium in 2 tablespoons of sweet pickle relish.

15. Swiss Chard and beet greens

These leafy green vegetables like swiss chard and beet greens have a good content of nutrients and minerals including potassium. In the raw green leafy vegetables the content of potassium varies from 140-290 mg per cup. There should be a moderate intake of these foods as they have a high oxalate content as well.

16. Dates, raisins and prunes

Dates, raisins, and prunes are common dry fruits. When fruits are dried, all of their nutrients are concentrated, including potassium.1 cup of prunes provides 1,274 mg of potassium, which is nearly 5 times the amount of potassium found in 1 cup of plums, its raw counterpart. 668mg of potassium content can be observed in four dates. This high amount of potassium in these common dry fruits is not good food for renal health.

17. Chips and crackers

Ready to eat snacks and food have a lack of nutrients and have a very high salt content. Also, these snacks are mainly made up of potatoes and it is already mentioned that the potato which needs to be avoided for having a healthy kidney.

18. Certain herbal supplements and vitamins

If you have a chronic disease then you should always consult a doctor before taking certain vitamins and supplements. These supplements may elevate portions of some vitamins A, E and K which might be a damage to the kidney.

19. Trans-fat

There should be a limit to the consumption of trans fat (or the “bad fats”) in your diet. It is particularly harmful as it can increase the risk of clogged blood vessels and heart disease. While healthy fats, such as those found in salmon, avocado, olive oil and nuts, are necessary, trans fat is not and is only harmful. Foods that contain trans fats, such as fried foods, pie crusts, crackers, frozen pizza, margarine and cakes should be avoided.

20. Alcohol

In order to avoid severe damage people with chronic kidney health conditions must avoid or limit alcohol. As per studies the drinking should be limited as in moderate drinking for women who are age 21 and older is one drink per day and up to two drinks per day for men.

Word of Wisdom

People nowadays do not consider a lot of their renal health before consuming anything. Most of the food items mentioned above in the list are consumed in daily diets. Many of them are not even considered to be even close to being harmful to the kidney. But the sad truth is the fact that all these can ruin your Kidneys' life. It's time we start caring about our bodies and take action to prevent organ damage. One should try consulting a kidney doctor for the best results.

Longtime House Democrat Passes Away

St. Louis, MO — Missouri Democratic Rep. William Lacy “Bill” Clay Sr., the first Black congressman from the state and a towering figure in American civil rights and politics, died Thursday at the age of 94. Clay, who represented Missouri’s 1st Congressional District from 1969 until his retirement in 2001, leaves behind a legacy that spanned over three decades in the U.S. House and reshaped both St. Louis and the broader political landscape of the nation.

For many, Clay was more than a politician; he was a fighter, an architect of progress, and a bridge between the Civil Rights Movement of the 1960s and the halls of Congress where laws reflecting that struggle were debated and passed. His career was marked by perseverance, vision, and an unwavering commitment to justice.

William Lacy Clay Sr. was born on April 30, 1931, in St. Louis, Missouri, into a city defined as much by its contradictions as its possibilities. St. Louis, with its iconic Gateway Arch and reputation as the “Gateway to the West,” was also a city fractured by redlining, segregation, and entrenched racial inequality. It was within this environment that Clay came of age, sharpening both his sense of justice and his political instincts.

By the age of 28, in 1959, Clay made his first political breakthrough when he was elected to the St. Louis Board of Aldermen, becoming one of the youngest members to serve. His rise came at a pivotal time. Across America, Black communities were mobilizing in the aftermath of the 1954 Brown v. Board of Education decision and the burgeoning Civil Rights Movement. Clay’s early involvement in sit-ins, protests, and labor organizing in St. Louis foreshadowed the lifelong commitment he would carry into Congress.

In a 1998 profile, Clay reflected on the challenges of his youth in segregated St. Louis. “St. Louis was no different from any of the cities in the South,” he said. “We had rigid segregation — not by law, but by custom.” That reality pushed Clay to activism and, ultimately, to political leadership.

Civil Rights Champion in St. Louis

Before reaching Washington, Clay made his mark as a local civil rights advocate. He joined sit-ins against discriminatory businesses, including national chains like White Castle and Howard Johnson, that enforced segregation by dividing Black and white customers into separate areas. Clay was arrested more than once in the pursuit of equality, but he viewed those moments as badges of honor, emblematic of the larger struggle.

As an alderman, Clay confronted entrenched systems of discrimination in housing, policing, and employment. St. Louis, like many Northern cities, practiced a form of segregation just as destructive as Jim Crow laws in the South — exclusionary zoning, discriminatory lending, and systematic underfunding of Black neighborhoods. Clay was among the first in the city’s political establishment to openly challenge those practices.

He also built alliances with organized labor, seeing the power of unions as intertwined with the fight for racial equality. That relationship would remain central throughout his congressional career, helping him push for workers’ rights, minimum wage increases, and improved labor standards.

From Local Leader to National Voice

In 1968, at the height of social upheaval following the assassination of Dr. Martin Luther King Jr., Clay ran for Congress. His campaign tapped into the frustration and determination of St. Louis’ Black community, who were demanding representation equal to their population and influence. He won decisively, becoming Missouri’s first Black member of Congress in 1969.

Clay entered Washington during a time of tremendous change. The Civil Rights Act (1964) and Voting Rights Act (1965) had become law, but the fight for economic justice and equal opportunity was far from over. In Congress, Clay positioned himself as both a legislator and an activist, never shying away from confrontation when necessary.

In 1971, Clay co-founded the Congressional Black Caucus (CBC) alongside 12 other African American lawmakers. The group sought to amplify Black voices within the House, coordinate legislative strategy, and ensure that issues affecting African Americans received national attention. Today, the CBC boasts a record 62 members in the 119th Congress, a testament to Clay’s vision.

Legislative Achievements

Clay’s three decades in Congress were marked by significant legislative accomplishments. He was instrumental in shaping policies around labor rights, family protections, and social justice. Among the most notable:

Family and Medical Leave Act (FMLA): Clay played a key role in advancing the FMLA, which guaranteed millions of American workers the right to take unpaid leave for medical or family reasons without fear of losing their jobs. The landmark legislation, signed into law in 1993, remains a cornerstone of workers’ rights.
Raising the Minimum Wage: Clay was a consistent advocate for raising the federal minimum wage, arguing that economic justice was inseparable from civil rights. His efforts helped pave the way for periodic wage increases, lifting millions of workers out of poverty.

Urban Development in St. Louis: Clay used his influence to channel federal investments into St. Louis, negotiating with corporate leaders and trade unions to ensure that development projects benefited both the city’s skyline and its working-class residents. His work was instrumental in the city’s partial recovery following the exodus of white residents — often called “white flight” — after desegregation.

Civil Service Reform: Clay was also deeply engaged in oversight of federal employment policies, working to protect public employees and ensure fairness in hiring and promotions.

A Political Force — and a Demanding Ally

Clay was known for his political savvy and his ability to wield endorsements as powerful tools. Within Missouri’s Democratic Party, his support could make or break campaigns. Prominent Democrats often sought his blessing, aware that he expected loyalty in return.

“The Black community, almost overwhelmingly, looked at him as a fighter for them,” said his son, former Congressman Lacy Clay Jr., who succeeded him in representing Missouri’s 1st District until 2021.

That reputation as a fighter sometimes meant sharp elbows, but it also solidified his standing as one of the most influential Black lawmakers of his era.

Tributes Pour In

Following news of his passing, tributes poured in from across Missouri and the nation.

St. Louis Mayor Cara Spencer praised Clay’s “courageous legacy of public service to St. Louis and the country,” highlighting his role in historic legislative battles on behalf of the poor and disenfranchised. “Millions have him to thank for the Family and Medical Leave Act and raising the minimum wage,” she said.

Congressman Wesley Bell (D-MO) described Clay as “a giant — not just for St. Louis, not just for Missouri, but for the entirety of our country.” Bell called him a mentor, trailblazer, and friend, adding, “I carry his example with me every time I walk onto the House Floor.”

The Congressional Black Caucus released a statement declaring: “Congressman Bill Clay leaves behind a legacy of dignity, courage, and transformative impact. His work laid the foundation for future generations of Black leadership in public service. May he rest in power and everlasting.”

Michael P. McMillan, president and CEO of the Urban League of Metropolitan St. Louis, said Clay “was a giant in the Congress and a civil rights pioneer who helped transform St. Louis and change the lives of countless people locally and nationally.”

Building the St. Louis Legacy

Clay’s impact on St. Louis is visible in the city’s development. During his tenure, he worked tirelessly to secure federal dollars for infrastructure, housing, and education projects. His ability to “barter with construction trades and corporate C-suites,” as one colleague put it, was central to reshaping St. Louis’ skyline.

The Gateway Arch, the city’s most recognizable landmark, came to symbolize not only westward expansion but also the resilience of a city navigating profound demographic and economic shifts. Clay ensured that Black workers, unions, and small businesses were not left behind in these projects.

Family and Personal Life

Clay married Carol Ann Johnson in 1953, and together they raised a family that became deeply enmeshed in public service. His son, Lacy Clay Jr., carried on his father’s legacy in Congress for two decades, from 2001 until 2021.

Though known for his political toughness, Clay was also remembered by friends and family as warm, witty, and deeply devoted to his community. He often returned to St. Louis to engage directly with residents, attending church services, neighborhood meetings, and civic events.

The Broader Impact

Bill Clay Sr.’s life and career cannot be measured solely by the legislation he authored or the elections he won. His influence extended into the very fabric of American democracy. By co-founding the Congressional Black Caucus, he institutionalized a space for Black lawmakers to speak collectively and strategically. By challenging segregation in St. Louis, he helped pave the way for future generations of Black leadership in the city and state.

For many in Missouri, Clay represented the possibility of a more inclusive democracy. His life demonstrated that progress was not inevitable but earned through persistence, negotiation, and at times confrontation.

Final Reflections

As the nation reflects on Clay’s passing, his story serves as both a reminder of the struggles of the past and a guide for the challenges of the future. In an America still grappling with racial inequality, Clay’s insistence on tying civil rights to economic rights remains strikingly relevant.

His legacy is etched not just in history books but in the daily lives of workers who can take family leave, of citizens who saw their neighborhoods revitalized, and of Black leaders who walk the halls of Congress today because he helped clear the path.

“Bill Clay Sr. was ahead of his time,” one colleague noted. “He didn’t just represent St. Louis — he represented possibility.”

As tributes continue to pour in, one thing is clear: Bill Clay Sr.’s 94 years left an indelible mark on St. Louis, on Missouri, and on the United States of America. His name will endure as a symbol of dignity, courage, and transformation.
