Ammonia-Reducing Diet: Foods To Eat And Avoid

how reduce ammonia diet

High ammonia levels in the body, also known as hyperammonemia, can be life-threatening and require immediate medical treatment. Ammonia is a byproduct of protein digestion and bacterial metabolism in the gut. The liver is responsible for processing ammonia and converting it into urea, which is then released through urine. Liver malfunctions or issues with the urinary cycle can cause ammonia levels in the blood to increase. To reduce ammonia levels, it is recommended to make dietary changes, such as reducing animal protein intake, especially red meat, and increasing vegetable protein sources like beans, which release ammonia more slowly due to their slower digestion. Probiotics, including yogurt and sauerkraut, are also beneficial as they aid in digestion and help eliminate ammonia. Additionally, medications like lactulose and rifaximin can be prescribed to decrease ammonia production and absorption in the intestines.

Eat a vegetarian diet

Eating a vegetarian diet is a great way to reduce ammonia levels in the body. This is because vegetable protein, such as beans, takes longer to digest than animal protein, giving the body more time to dispose of the ammonia created during digestion. Research has shown that eating a vegetarian meal can help lower ammonia levels in people with severe liver disease.

A clinical trial found that serum ammonia levels were significantly higher in those who ate a meat-based meal compared to those who ate a vegetarian or vegan meal. The study also revealed that a single meal change from meat to vegetarian or vegan can reduce ammonia generation. This suggests that even occasional substitutions of meat with plant-based proteins can help reduce ammonia levels without requiring a complete diet change.

A vegetarian diet can also provide more dietary fiber and amino acids, which help balance ammonia levels. Additionally, vegetable-based proteins have been associated with a positive nitrogen balance and decreased excretion of urine nitrogen compared to animal or mixed protein diets. This indicates that a vegetarian diet may be beneficial for individuals with cirrhosis and hepatic encephalopathy (HE).

It is important to note that everyone's needs are different, and consulting with a doctor is essential to create a personalized plan for managing ammonia levels. This plan should include a good understanding of your diet and protein intake, as high ammonia levels are often linked to medical conditions such as liver disease or hepatitis.

Reduce animal protein intake

Reducing your animal protein intake can be beneficial for your health and the planet. Animal agriculture is the biggest user of agricultural land, occupying around a third of the world's ice-free land. It is also responsible for 20-33% of all freshwater consumption and 18% of global greenhouse gas emissions.

A shift towards a more plant-based diet can be beneficial for your health. Research has shown that higher plant protein intake is associated with lower all-cause and cardiovascular disease (CVD)-related mortality. Replacing red and processed meat with plant-based proteins has been linked to lower total, cancer-related, and CVD-related mortality. A 12-week clinical trial found that replacing animal proteins with plant-based proteins led to increased fibre intake, improved dietary fatty acid composition, and a more favourable plasma lipoprotein profile.

Additionally, reducing animal protein intake can help lower ammonia levels in the body. High ammonia levels, or hyperammonemia, are often caused by liver issues. Vegetable proteins, such as beans, digest more slowly than animal proteins, giving the body more time to dispose of the ammonia created during digestion.

If you want to reduce your animal protein intake, you can start by cutting out animal protein one to two days a week. You can also try to source meat from local, organic, and free-range companies, and reduce packaged foods that contain meat products. Incorporate more plant-based alternatives, such as beans and vegetables, into your diet. It is important to note that everyone's needs are different, and you should consult with your doctor to create a personalized plan that takes into account your dietary needs and health goals.

Include probiotics in your diet

Probiotics are live microorganisms, mostly bacteria, that can improve your health when consumed in adequate amounts. They are known to reduce inflammation and oxidative stress in liver cells, which increases hepatic clearance of ammonia and reduces the uptake of other toxins. Probiotics also inhibit bacterial urease activity, decrease intestinal permeability and bacterial urease secretion, and increase ammonia excretion.

Probiotics work by enriching the gut flora with non-urease-producing microorganisms, which decrease ammonia production. They can also directly consume ammonia, rather than altering the environment in the intestine. For example, the probiotic strain L. plantarum contributes to ammonia reduction by directly consuming ammonia.

Probiotics can also reduce the total amount of ammonia in the portal blood. As most probiotics produce acids that reduce the pH in the intestine, ammonia absorption also decreases. Oral ingestion of specific probiotics can promote the growth of non-urease-producing bacteria in cirrhotic patients and reverse the imbalance of coliform microorganisms seen in cirrhosis. After three months, probiotics appeared to reduce plasma ammonia levels in HE patients by an average of 7 μmol/L.

In addition, researchers are looking to specifically genetically engineer probiotics to act as novel, living medicines. A human trial tested the safety of a non-pathogenic strain of E. coli, which was engineered to clear excess ammonia from a person's large intestine. This trial passed its first phase.

Take medication

High ammonia levels, also known as hyperammonemia, are often caused by issues with the liver. The liver is responsible for processing ammonia and converting it into urea, which is then released in urine. In some cases, infections or issues with the urinary cycle can also cause ammonia levels in the blood to increase.

If you are experiencing high ammonia levels, it is important to seek medical advice as soon as possible. Your doctor will likely recommend a combination of dietary changes and medication to reduce your ammonia levels. Here are some medications that can help:

Lactulose

Lactulose is a medication that can help reduce ammonia levels in the blood. It is a synthetic sugar that decreases the production and absorption of ammonia in the intestines, causing it to be drawn from the blood into the colon for excretion. While it is effective, it may cause side effects such as diarrhoea, gas, and nausea. It is important to stay hydrated when taking Lactulose to avoid dehydration.

Rifaximin

Rifaximin is an antibiotic that can be used to reduce ammonia levels, especially if high ammonia levels are due to ammonia-producing bacteria. It helps to reduce the number of these bacteria and can be combined with Lactulose to further lower ammonia levels.

AST-120 (Spherical Carbon Adsorbent)

AST-120 is a medication that has shown promise in absorbing ammonia from the blood in people with hepatic encephalopathy. A 2019 review found it to be more effective than a placebo in reducing ammonia levels. However, more studies are needed to confirm its safety and effectiveness.

Sodium Benzoate and Phenylacetate

Intravenous sodium benzoate and phenylacetate are used to treat high ammonia levels, especially in comatose neonates with hyperammonemia. These medications are typically administered when plasma ammonium levels are extremely high and require prompt medical attention.

Arginine Supplementation

Arginine is an essential amino acid that can be given as a supplement to patients with urea cycle defects, which can lead to hyperammonemia. Citrulline can also be given as a source of arginine in certain cases, but it is important to consult with a healthcare provider to determine the appropriate treatment.

Remember, it is important to consult with your doctor before taking any medication. They will be able to advise you on the most suitable treatment plan based on your individual needs and health status.

Limit protein after symptom flare-ups

Ammonia is a byproduct of protein digestion in the body. If you are experiencing abnormally high levels of ammonia in the blood, it is important to limit your protein intake. High levels of ammonia are usually identified due to an increase in symptoms.

If you are experiencing abnormal brain function, it is a good idea to limit protein intake as your body recovers. This is because high ammonia levels can be toxic to the brain and nervous system, causing confusion, irritability, and even seizures or coma in extreme cases.

You can also try eating more vegetables, like beans, carrots, and broccoli, instead of red meat. Vegetable proteins release ammonia more slowly because they take longer to digest. Research shows that eating a vegetarian meal could help reduce ammonia levels for people struggling with severe liver disease.

In addition, probiotics contain good bacteria that help your body digest food, so try eating foods high in probiotics, like yogurt, kefir, or sauerkraut. Probiotics can help the gut to digest and eliminate ammonia more effectively.
