Can you eat chocolate with CKD?

In this brief article we are going to answer the question “can you eat chocolate with CKD?. We will also discuss the effect of dark chocolate on kidney function.

Can you eat chocolate with CKD?

No, You can not eat chocolate with CKD. Phosphorus is abundant in dark chocolate. Patients with chronic kidney illness are at increased risk for phosphate accumulation, which has been linked to bone disease and irritation. Due to this, people with CKD should generally avoid eating too much chocolate. 

Due to its high potassium concentration, chocolate may be discouraged by doctors and nutritionists who are treating patients with severe kidney disease. 

The National Kidney Foundation warns that a high potassium level might lead to arrhythmias or a heart attack. Ask your doctor before eating chocolate if you have kidney illness. 

They will most likely base their decision on your potassium testing levels. The normal range for potassium is 3.5-5 milligrams per deciliter. 

The cocoa bean, from which chocolate is derived, is widely acknowledged as one of nature’s most delightful pleasures, and for good reason as it is packed with nutrients like flavonoids, minerals, vitamins, and antioxidants.  

When it comes to the kidneys, there is currently no evidence that chocolate or any of its constituents is harmful. However, due to its high potassium and mineral content, chocolate may be dangerous for those who already suffer from CKD.

Does Eating Dark Chocolate Affect Kidney Function?

Dark chocolate has been linked to a variety of health advantages, but those with chronic kidney disease should be wary of its high k and ph content. 

When looking for foods high in potassium, keep in mind that cocoa is on the list. As much as 158 mg of k can be found in one ounce of dark chocolate. About 722 mg of k can be found in a 3.5-ounce bar of dark chocolate (with 70%-85% cacao).

Since the kidneys are unable to filter out extra nutrients, high levels of potassium and phosphorus, for example, might be harmful. The National Kidney Foundation (NKF) warns that elevated potassium levels can lead to vomiting, irregular pulse, and even a heart attack. 

Taking in between 1,500 and 2,700 milligrams of potassium per day is recommended by the National Kidney Foundation (NKF) to help keep your kidneys healthy and your body functioning normally.

Dark chocolate contains 87 milligrams of phosphorus per ounce and up to 311 milligrams in each 3.5-ounce bar. When the kidneys are damaged, phosphorus builds up in the blood, which can lead to other health issues, especially with the heart and bones. 

Calcium is drawn out of the bones and into the blood vessels by the phosphorus, which weakens the bones, aggravates joint discomfort, and clogs the blood vessels.

How does one’s diet play a role in kidney disease?

The severity of renal illness determines the extent to which a person can change their diet. To give just one example, those with chronic kidney disease in the beginning stages will have varied dietary restrictions than those with kidney failure in its latter stages.

Dialysis patients with end-stage renal failure have various dietary limitations. During dialysis, excess fluid is drained and waste products are filtered. Most people with the advanced renal disease will need to eat a kidney-friendly diet to prevent dangerous levels of toxins and nutrients from building up in the blood.

Chronic renal disease results in impaired salt, potassium, and phosphorus excretion. They are thus more likely to have abnormally high blood concentrations of these minerals. Sodium, potassium, and phosphorus intake are typically restricted on a renal diet so that the total daily intake is less than 2,300 mg.

Recent guidelines from the National Kidney Foundation’s Kidney Disease Outcomes Quality Initiative (KDOQI) do not recommend adhering to any particular potassium or phosphorus intake levels.

Patients with kidney disease should consult their doctor or dietician to establish safe potassium and phosphorus intake levels depending on their individual test results. Protein breakdown byproducts may be particularly difficult for renal disease patients to filter. 

As a result, unless they are on dialysis, people with chronic renal disease, particularly stages 3 to 5, should reduce the quantity of protein they eat. On the other hand, people with ESRD who are receiving dialysis have a higher protein demand.
