Why Isnt Coffee Good For Health
A lot of people like to start drinking coffee every day. They often think that it will give them a better energy boost as well as make them feel good. But there is more to coffee than just an energy boost.
Thereâs more coffee that a lot of people donât realize. It is true that this can give you energy but you should be very careful when doing so since many negative effects come from drinking too much coffee.
One of the most common side effects derived from coffee is called Java breath. Itâs a related bad breath. This is not normal and can also affect social life.
This is because many coffee drinkers do not brush their teeth after they drink them. The reason why this happens is that coffee is mixed with saliva, which then goes into the mouth starting to produce more coffee.
Blood Pressure And Kidney Function
High blood pressure can be a big factor in developing kidney disease. Its only second to diabetes in risk factor. There is some evidence that caffeine-containing coffee causes a momentary spike in blood pressure. However, it is thought that these effects are exaggerated in older patients not accustomed to the impact and those with a history of high blood pressure.
Due to this correlation, some believe excess coffee consumption may be detrimental to kidney health, especially in sensitive individuals. Despite this, most data shows that there is a minimal risk as long as coffee consumption remains below four cups daily.
If you are concerned about coffees effects on your kidneys, make sure to moderate your consumption over the day and be sure to contact your urology specialist.
Coffee Recommendations For Liver Health
How much coffee should you drink? In this case, less is not more.
We recommend at least three cups every day to help prevent liver problems, Dr. Wakim-Fleming says. And if you have hepatitis or fatty liver disease, even more as many as four, five or even six cups a day might be helpful.
However, not everyone can handle that much coffee without bouncing off the walls . It can trigger headaches, difficulty initiating sleep, anxiety and jitters in some people. Dr. Wakim-Fleming only suggests going this route if you can tolerate it.
If you have an irregular heart rate or other heart problems, excessive coffee might be dangerous. Coffee might also cause problems if you have lung cancer. In such cases, steer clear until you talk to your doctor for advice.
If you can drink coffee without any problems, skip the cream and sugar. Since people with fatty liver disease often have problems like diabetes and obesity, its especially important not to add extra fat and sugar to your coffee. Black coffee is best, Dr. Wakim-Fleming says. If you just cant stomach it black, swap sugar for artificial sweeteners. Add skim milk or plant-based milk instead of cream.

Caffeine And Kidney Stones
Caffeine consumption has been linked to kidney stones. Calcium oxalate stones, the most common type of kidney stone, are formed from the combined crystals of calcium and oxalate. In a study reported in the August 2004 “Journal of Urology,” study participants who had a history of calcium kidney stones but normal serum calcium levels were given 6 milligrams of caffeine per kilogram of body weight after fasting for 14 hours. The caffeine increased urinary calcium levels, causing researchers to conclude there was a modest increase in the risk of developing calcium oxalate kidney stones after caffeine consumption.
Does Coffee Affect Kidney Health
You’ve read all of the health benefits of black coffee and how it can help you lose weight, how coffee grounds are good for your skin, and that it can even help you live longer. But what about inside your body? There have been articles stating that coffee can be bad for you, especially your kidneys, and we’re here to challenge that theory.
Facts have shown that drinking around 3-4 cups of coffee a day can actually help your kidneys and does not lead to Kidney Disease. Additionally, a recent study from last year suggests that caffeine can help people with chronic kidney disease live longer.
Caffeine increases your heart rate and expands your blood vessel diameter, and it regulates blood flow throughout your body. As a result of the increase in blood flow, the toxins and metabolites are filtered out of your blood through your kidneys faster.
Overall, caffeine can only help your kidneys do their job a little faster than normal.
As always, if you’re concerned about how coffee can affect your health, talk to your doctor!

The Amount Of Coffee You Drink
First thing to consider is the nutritional content of coffee. An 8 oz. cup of black coffee has 116 mg of potassium3. This is considered a low potassium food. However, many people drink more than one cup of coffee each day. Three to four cups of coffee a day is considered high in potassium and could raise your potassium levels. Adding creamers or milk can further raise your coffees potassium content. Drinking less than three cups of coffee/day is generally considered safe. Phosphorus, sodium, calories, carbohydrates and protein are minimal in black coffee and not of nutritional consideration.
Effects Of Caffeine Consumption On Kidney Stone Disease
Although the effects of caffeine on the kidney have been extensively studied, its influence in kidney stone disease seems to be overlooked. The evidence on whether caffeine prevents or promotes kidney stone disease has recently become more clear. Because an increase in fluid intake is widely recommended for the prevention of kidney stone formation, some previous studies during the past 2 decades focused on the relevance of the type of consumed beverages, including caffeinated beverages, in association with kidney stone incidence. In 1996, the first cohort data retrieved from the Health Professionals Follow-Up Study in 45,298 male participants who had no history of kidney stones were reported . The findings showed that not all types of beverages affect kidney stone disease. Only caffeinated coffee and decaffeinated coffee and tea, but not caffeinated and noncaffeinated sodas, are associated with an 10% lower risk of kidney stone incidence .
In 1998, the Nurses Health Study , another cohort study in 81,083 female participants who had no history of kidney stones reported the association between beverage consumption and a lower risk of kidney stone disease . The data showed a 10%, 9%, and 8% lower risk of kidney stone formation in the participants who consumed caffeinated coffee, decaffeinated coffee, and tea, respectively .

What Harms The Kidneys
Foods rich in animal protein are not suggested if you have kidney problems, as a diet high in protein can aggravate these conditions. Avoid eating meat, eggs, dairy, and other animal protein sources. Metabolizing the proteins causes the kidneys to enlarge and adds stress to other organs.
Uric acid is a toxic substance that accumulates in the body. This harmful substance can cause damage to the kidneys as well as other organs. Blending and drinking a cup of cranberries with water and lemon juice cleanses the kidneys of uric acid.

Assessment Of The Outcome And Covariates
The main outcome of interest for the present study was 1-year changes in kidney function, assessed by changes in eGFR estimated indirectly from serum creatinine using the Chronic Kidney Disease Epidemiology Collaboration equation for Caucasian individuals. SCr levels were determined by the enzymatic creatinine assay method . The secondary outcome was a rapid decline of kidney function, defined as 1-year eGFR decline rate> 3 mL/min/1.73 m2. This threshold represents a magnitude of change that is 3 times the decline rate imposed by natural ageing.
Caffeine As A Diuretic
Caffeine, which belongs to a class of substances called methylxanthines, is a mild diuretic. Theophylline, another drug in this class, was actually used as a diuretic until more potent diuretics were developed. Both of these drugs act on the kidneys by preventing absorption of water. Research reported by R.J. Maughan and J. Griffin in the December 2003 “Journal of Human Nutrition and Dietetics” noted that people who had not had any caffeine for a few days had increased urinary output after drinking the amount of caffeine equivalent to two to three cups of coffee.

What Does All Of This Actually Mean
Well, this means that people who consumed more than 24 oz of coffee a day, or more, were less likely to get kidney cancer than those who drank less. However, coffee can also be dangerous. It may lower your chances of kidney cancer, but there are huge dangers that can occur from excessive coffee consumption, such as:
Hydrochloric Acid: When you drink your delightful morning coffee each and every morning, this causes hydrochloric acid to be produced in your stomach. The problem with this is that hydrochloric acid should only be produced to digest food, and your body cannot produce huge amounts of it regularly, meaning your body may struggle to digest food later on in the day.
Especially indigested protein, this can cause bloating and gas, and even colon cancer. While this may not cause kidney cancer, colon cancer is just as serious, and therefore needs to be recognised as a side effect of excessive coffee consumption.

Irritation: Coffee can also irritate your stomach lining, this can cause problems to people who suffer from ulcers, or other stomach problems. However, coffee can help provide the nutrients that parasites need to survive in the stomach, which makes any infection survive longer which you obviously dont want.
Coffee May Be Kind To Your Kidneys
That’s the suggestion of a new study that found that among more than 2,300 Americans with chronic kidney disease, those who drank the most caffeinated drinks reduced their risk of premature death by 24 percent.
“Our study showed a dose-dependent protective effect of caffeine consumption on all-cause mortality among patients with chronic kidney disease,” said lead researcher Dr. Miguel Bigotte Vieira, from the Centro Hospitalar Lisboa Norte, in Lisbon, Portugal.
“However, our observational study cannot prove that caffeine reduces the risk of death, but only suggests the possibility of such a protective effect,” he said.
Moreover, the reasons that caffeine might be protective aren’t clear, and how much caffeine is too little and how much might be too much also isn’t known, Bigotte Vieira added.
The findings also need to be replicated in a trial that compares caffeine consumption with no caffeine consumption before patients are counseled to drink more coffee or other caffeinated drinks, he noted.
In the study, the research team found that:
- those who consumed the least amount of caffeine saw no reduction in death risk,
- those who had the second higher amount reduced their risk by 12 percent,
- those who had the third higher amount reduced their risk by 22 percent,
- and those who consumed the most caffeine reduced their risk by 24 percent.

Not Drinking Enough Water
Staying well hydrated helps your kidneys clear sodium and toxins from the body. Drinking plenty of water is also one of the best ways to avoid painful kidney stones. Those with kidney problems or kidney failure may need to restrict their fluid intake, but for most people, drinking 1.5 to 2 liters of water per day is a healthy target.
Chronic Kidney Disease And Diet
From 1990 to 2010, the incidence of Chronic Kidney Disease has doubled. In a review of the standard American diet and its effects on the kidney, the diet appears to have negative effects on human renal function. A decline in renal function was observed in those who consumed an animal protein-rich diet, as compared to those consuming a plant protein-rich diet. Consumption of excessive animal proteins leads to a marked acid load to the kidney, and has been associated with the development of kidney stones. Higher meat consumption leads to increased renal acid excretion and the production of ammonia, which can cause metabolic acidosis and a higher risk for tubulointerstitial injury. In addition to eliminating meat, it is beneficial to add dietary fiber. In a meta-analysis of 14 trials involving 143 participants, the additional dietary fiber significantly reduced serum urea and creatinine levels.
Consumption of animal products impairs renal vascular function, leading to increased inflammation and subsequent microalbuminuria. Studies show that meat ingestion impacts factors such as GFR, glucagon, prostaglandins, and increased albuminuric response. Glomerular hyperfiltration is thought to be due to an inflammatory response via vasodilatory prostaglandins, as a result of animal protein consumption. This is supported by studies showing that the level of hyperfiltration decreases when indomethacin is administered.

Medications That Can Harm The Kidneys
No matter what kind of medicine you take, whether OTC or prescription, it is destined to take a trip through your kidneys. Taking a drug the wrong way or in excessive amounts can damage these vital, bean-shaped organs and lead to serious complications. In the worst-case scenario, it could necessitate a kidney transplant.
Compared with 30 years ago, patients todayhave a higher incidence of diabetes and cardiovascular disease, take multiple medications, and are exposed to more diagnostic and therapeutic procedures with the potential to harm kidney function, according to Cynthia A. Naughton, PharmD, senior associate dean and associate professor in the department of pharmacy practice at North Dakota State University. All of these factors are associated with an elevated risk of kidney damage.
An estimated 20% of cases of acute kidney failure are due to medications. The technical term for this scenario is nephrotoxicity, which is growing more common as the aging population grows, along with rates of various diseases.
The kidneys get rid of waste and extra fluid in the body by filtering the blood to produce urine. They also keep electrolyte levels balanced and make hormones that influence blood pressure, bone strength and the production of red blood cells. When something interferes with the kidneys, they cant do their job, so these functions can slow down or stop altogether.
Choose Your Milk Or Creamer Carefully
Many coffee creamers come with added phosphates. This can be especially true in powdered creamers.

Caffeine in coffee, tea, soda, and foods can also place a strain on your kidneys. Because caffeine is a stimulant, it can stimulate blood flow, increasing blood pressure and stress on the kidneys. A 2002 study in Kidney International showed that long-term caffeine consumption exacerbated chronic kidney failure in obese and diabetic rats.
Caffeine and Kidney StonesCaffeine consumption has also been linked to kidney stone formation by increasing calcium excretion in urine. Calcium oxalate stones, the most common type of kidney stone, are formed from the combined crystals of calcium and oxalate. In a study reported in the August 2004 Journal of Urology, study participants who had a history of calcium kidney stones but normal serum calcium levels were given 6 milligrams of caffeine per kilogram of body weight after fasting for 14 hours. The caffeine increased urinary calcium levels, causing researchers to conclude there was a modest increase in the risk of developing calcium oxalate kidney stones after caffeine consumption.
Caffeine in ModerationCaffeine in moderate doses the University of Illinois suggests 200 to 300 milligrams of caffeine a day probably wont cause health problems. The amount of caffeine suggested is the equivalent of one or two cups of coffee, three cups of tea or three 12-ounce soft drinks. And dont forget other sources of caffeine, such as energy drinks, chocolate, cocoa and some medications, including over-the-counter pain medications.
Study Design And Participants
The present data was analysed using an observational prospective design conducted within the frame of the PREDIMED-PLUS study, which included 6874 older adults enrolled between 2013 and 2016 by 23 Spanish centers working in collaboration with 208 National Health System primary care clinics. Briefly, PREDIMED-Plus is an ongoing, 6-year, multicenter, parallel randomized clinical trial evaluating the long-term effect of a weight-loss intervention based on an energy-reduced Mediterranean diet , physical activity promotion and behavioral support , in comparison with usual-care recommending an energy-unreduced MedDiet , on primary cardiovascular prevention. Eligible participants were overweight/obese men and women aged 5575 years harboring the MetS, but free of cardiovascular disease at enrollment. More specific details of the study cohort and inclusion/exclusion criteria have been reported, and the protocol is available at . Local Ethics Committee approved the study protocol and all participants signed a written informed consent.
For the current study, participants who did not complete the semiquantitative food-frequency questionnaire at baseline or those whose total energy intake was outside pre-defined limits were excluded. We also excluded subjects who died or were lost to follow-up within first year of follow-up, and who had missing data on eGFR at baseline or at the 1-year assessment. The remaining 5851 participants comprised the final sample.
