Beef Kidney on Carnivore Diet: A Superfood + 10 Best Recipes

Beef kidney is a real superfood you can include on a Carnivore Diet. Organ meats like kidneys contain nutrients that muscle meat alone cannot provide. If you are looking for a nutritious food source to help you regulate hormones, metabolism, and the immune system, and provide high-quality macronutrients, you should learn how to make Carnivore meals with beef kidney. So, let’s learn about the pros and cons of cow kidney and learn 10 quick and easy recipes.

What Is Beef Kidney?

Beef kidney, or cow kidney, comes from the urinary system of the cow. Its role is to filter the animal’s blood and regulate minerals, not to store toxins.

You can buy beef kidney whole or pre-sliced. You need to trim and clean whole kidneys yourself, while sliced versions are more convenient but sometimes require additional rinsing to reduce odor.

Most grass-fed and pasture-raised farms offer kidneys at a very low cost, so they can be one of the most economical, nutritious foods you can buy.

Although less popular today, the kidney was a main food in many traditional cultures. Also, these days, many individuals who look for clean and nose-to-tail eating methods are rediscovering the values of organ meats.

So, if you buy beef kidney from trustworthy sources and healthy animals and use proper recipes, it can be a safe and nutritious food source, especially for those who follow low-carb, animal-based diets like Carnivore and Keto.

Nutrients in Beef Kidney

Beef kidney is low in calories and contains high levels of key macronutrients, especially protein. Let’s see what and how many nutrients are found per 100 grams of cooked beef kidney according to the USDA [1].

Because the beef kidney is naturally lean, you can consume it with tallow, suet, or butter, which can balance macros, improve flavor, and increase a feeling of fullness.

Kidney’s selenium, B12, and riboflavin content are essential for energy metabolism, methylation, thyroid function, and antioxidant defense.

Selenium is especially important for those on a Carnivore Diet, who rely only on animal-based sources for micronutrients.

Beef Kidney in a Carnivore Diet

On a Carnivore Diet, you should gain your daily macros from different animal-based foods. Muscle meat alone cannot provide the required levels of selenium, B12, riboflavin, folate, or other essential micronutrients [2].

This is why many individuals consume organ meats like the kidney. Unlike the liver, the kidneys do not contain excessive vitamin A, so you can eat them safely more frequently. It also fills nutrient gaps that muscle meat cannot [3].

Additionally, the kidneys’ low fat-to-protein ratio helps you manage macros based on your goals. If you are on a high-protein, moderate-fat Carnivore, beef kidney is a good fit. If you are on a high-fat Carnivore, simply add suet, tallow, or butter.

You do not have to consume beef kidney every day, but it can be a nutritious weekly part of your Carnivore Diet meal plan because of its nutrients and health benefits.

Beef Kidney Health Benefits

One of the main benefits of beef kidney is its high selenium content. Selenium helps immune health, fertility, metabolic regulation, and thyroid hormone function [4] [5].

Since plant-based foods are not allowed on a Carnivore diet, you need to consume animal organs like the kidney to provide antioxidants and regulate hormones, especially thyroid [6].

The kidney contains B vitamins, especially B12 and B2, which help red blood cell formation, energy production, mood regulation, and neurological health. A single serving of kidney can provide these vitamins for several days [7].

Another advantage is protein quality. The amino acid profile of beef kidney is very bioavailable, meaning that it helps muscle maintenance and tissue repair.

Beef Kidney Risks and Concerns

Despite its benefits, beef kidney may not be the best choice for everyone. It has high purine content, which can increase uric acid levels in sensitive individuals.

So, if you have diseases like gout or uric-acid-related kidney stones, you may need to limit or avoid beef kidney or consult your physician first.

Kidney is also high in cholesterol. While dietary cholesterol is not harmful for many on a Carnivore Diet, you should be cautious if you have genetic cholesterol disorders, such as familial hypercholesterolemia [8] [9].

Some people may also not like the taste and odor of beef kidneys. They can have a strong smell if they are not cleaned properly. Soaking and trimming help eliminate this, making it much more edible.

How to Prepare and Clean a Beef Kidney Before Cooking?

1. The first step is trimming the white membranes and connective tissue surrounding the lobes. This improves tenderness and removes the parts responsible for stronger flavors.
2. The next step is soaking, which is optional but highly recommended. Use cold saltwater, milk, or lemon water. Soak the kidney for 1-2 hours, and change the liquid once. This helps you get rid of unpleasant odor and soften the texture.
3. Then, you should cook the kidney quickly unless you are using it in a stew. Do not overcook it because it gets tough and develops a more intense flavor. Most stove-top kidney dishes take less than 6 minutes.
