Plant-Based Diets: Kidney Health And Scar Reduction

A plant-based diet can help prevent and slow the progression of chronic kidney disease. This is because plant-based diets are rich in fibre, vitamins and minerals, and can help manage weight, blood pressure, and diabetes.

Plant-based diets focus on whole grains, fruits, and vegetables, and may be beneficial for kidney health. They can help to lower the chance of getting kidney disease, or even keep early kidney disease from getting worse.

Plant-based diets can also help to lower blood pressure and cholesterol, which helps reduce the risk of heart disease. They can also improve antioxidant levels, which are compounds found in food that help protect cells from damage.

However, it is important to note that a plant-based diet may not be suitable for everyone with kidney disease, and it is always best to consult a healthcare professional before making any significant changes to your diet.

A plant-based diet can help manage weight, blood pressure, and diabetes

Weight management

Plant-based diets tend to be high in fibre, which makes people feel fuller for longer. They are also lower in fat and sugar, which helps with weight control.

Blood pressure management

Plant-based diets can lower blood pressure and cholesterol, reducing the risk of heart disease. This is because they are typically lower in animal-based protein, which can induce hyperfiltration, a state that temporarily overworks the kidneys. Plant-based diets are also typically lower in salt, which is important for people with kidney disease.

Diabetes management

Plant-based diets can lower the risk of developing diabetes and help manage the condition if it has already been diagnosed. This is because they are high in fibre, which decreases the glycemic load of carbohydrates, slowing the digestion rate of foods and reducing the insulin response.

Plant-based diets are rich in fibre, vitamins, and minerals

Fibre is a type of indigestible carbohydrate that is readily available in plant foods and which enters the digestive system via the consumption of plants or plant-based products. It has been shown to provide many health benefits and prevent chronic diseases. It can decrease serum urea and creatinine levels in chronic kidney disease (CKD) patients, which are common markers of an abnormal glomerular filtration rate (GFR). Fibre also promotes fermentation in the gut, which results in a downstream increase in beneficial short-chain fatty acids (e.g., butyrate, propionate and acetate) production and bile excretion. This upregulation serves to decrease serum cholesterol and glucose absorption while simultaneously increasing insulin sensitivity. With increased fibre intake, the gut microbiota shifts, increasing the quantity of microflora that process and break down fibre-rich foods. This microflora also traps protein nitrogen, resulting in increased nitrogen excretion, and therefore decreased urea in the bloodstream.

Vitamins and minerals are also abundant in plant-based diets. For example, plant-based diets are typically high in vitamin C and E, which are antioxidants. Antioxidants are compounds found in food that help protect your cells from damage. Plant-based diets are also rich in vitamin K1, which, in association with lower levels of phosphorus and reduced risk of metabolic acidosis, could have a beneficial effect on vascular calcifications and bone health.

Plant-based diets are also rich in minerals such as magnesium, which may have additional beneficial effects in counteracting vascular calcifications. They are also a good source of calcium, which is used by our body, along with phosphate, to maintain healthy bones. Phosphate is typically found in protein foods and wholegrain foods. However, phosphate is often added to many processed foods as an additive. A common feature of CKD is having too much phosphate in the blood. Over time, this can damage the bones and blood vessels. Plant-based diets can be naturally lower in phosphate. This is because we absorb less phosphate from plant foods than we do from animal foods.

Plant-based diets can reduce the risk of heart disease

Plant-Based Diets Reduce the Risk of Heart Disease

A plant-based diet can reduce the risk of heart disease in several ways. Firstly, it can help lower blood pressure and cholesterol, which are risk factors for heart disease. Plant-based diets are typically rich in potassium, which is known to improve blood pressure. They also tend to be low in saturated fat and cholesterol, which are found in meat, cheese, and eggs, and can lead to plaque buildup in the arteries.

Secondly, plant-based diets can aid in weight management. Plant-based foods usually have fewer calories than animal-based foods, helping to maintain a healthy weight and lower the risk of obesity, which is another risk factor for heart disease.

Additionally, plant-based diets are high in fiber, which has been shown to reduce cholesterol levels and improve overall heart health. They also contain antioxidants, which protect cells from damage and can help prevent heart disease and other conditions.

Furthermore, a plant-based diet can help reduce inflammation, which is a risk factor for heart disease and other health issues.

Finally, a plant-based diet eliminates or reduces the consumption of meat, especially processed and red meat, which have been linked to an increased risk of dying from heart disease.

It is important to note that the quality of plant-based diets matters. A diet consisting of whole, unprocessed plant foods is associated with a lower risk of cardiovascular disease compared to a diet that includes unhealthy plant-based options, such as fried foods and processed foods.

In conclusion, a plant-based diet can effectively reduce the risk of heart disease by addressing multiple risk factors. This is supported by multiple studies that have shown the benefits of plant-based diets in preventing, delaying, and even reversing heart disease and improving overall cardiovascular health.

Plant-based diets can help keep kidney disease from getting worse

A plant-based diet focuses on whole grains, fruits, and vegetables, and may benefit kidney health. It involves eating mostly whole grains, fruits, vegetables, legumes, unsalted nuts, and healthy oils, while reducing animal foods such as dairy, eggs, fish, meat, and poultry.

Benefits of a Plant-Based Diet for Kidney Health

Plant-based diets can help manage weight, blood pressure, and diabetes, which are common comorbidities of chronic kidney disease (CKD). They can also help with weight control as they tend to be high in fibre (so they are more filling) and lower in fat and sugar.

Plant-based diets have been shown to:

• Lower the chance of getting kidney disease, or even keep early kidney disease from getting worse.
• Lower blood pressure and cholesterol, which helps reduce your risk for heart disease.
• Lower your risk for diabetes.
• Improve antioxidant levels.
• Reduce the risk of weight gain.
• Lower the acid load and put less stress on your kidneys.
• Reduce the risk of bone and blood vessel damage.

Yes – in fact, a plant-based diet may even be beneficial as it may help to lower your blood pressure and cholesterol and help to maintain or achieve a healthy weight.

Yes, but it’s important to ask your kidney dietitian for personalised advice. This is because dialysis can sometimes result in malnutrition.

Potential Drawbacks of a Plant-Based Diet

A common concern with increased plant intake is the overconsumption or over-accumulation of minerals that are contraindicated in CKD patients, specifically in those with late-stage (stages IV and V) CKD. Late-stage CKD patients are at risk for hyperkalemia, or an overabundance of potassium in the blood, which can cause an irregular or abnormal heartbeat and put patients at greater risk for a cardiac event.

Plant-based diets can help lower the risk of getting kidney disease

Plant-based diets focus on whole grains, fruits, and vegetables, and may benefit kidney health. They can help manage weight, blood pressure, and diabetes. Plant-based diets have become very popular in recent years. They are rich in fibre, vitamins, and minerals that help lower your risk for heart disease and other health problems. Studies suggest they may even help keep your kidney disease from getting worse.

Plant-based diets are typically high in fibre, vitamins, and minerals that help lower your risk for heart disease and other health problems. Plant proteins such as beans and lentils are also cheaper to buy than meat and fish. Plant-based diets are more sustainable, so they're good for you, for your wallet, and for the planet!

Plant-based diets may also lower your risk of developing cardiovascular disease and diabetes and even help manage your diabetes if you already have this condition. Some studies show that a plant-based diet may help to slow down the progression of your kidney disease.

Plant-based diets can be naturally lower in phosphate. This is because we absorb less phosphate from plant foods than we do from animal foods and plant foods. Plant-based diets can also be naturally lower in salt. It is recommended that individuals with CKD get up to 30% of their total energy intake from fat sources. Although an ad libitum WFPB diet is not restrictive of lipid intake, it recommends a decreased consumption of processed oils and saturated fat.

A common concern with increased plant intake is the overconsumption or over-accumulation of minerals that are contraindicated in CKD patients, specifically in those with late-stage (stages IV and V) CKD. The minerals of greatest concern include potassium, phosphorus, and sodium. These minerals tend to be in higher abundance in plant foods, but findings indicate that there is less absorption of naturally-found minerals from plant foods than there is from animal sources.

There is also concern that a plant-based diet may be deficient in, or interfere with, the absorption of calcium, zinc, and iron. Nevertheless, the levels of these micronutrients have been reported to be sufficient in previous studies of plant-based diets, which did not demonstrate that reduced bioavailability has biological consequences. However, more research is still needed to carefully assess the potential for deficiencies in a WFPB diet in a clinical population with CKD.
