is oatmeal bad for dogs with kidney disease

Are oats/oatmeal good or bad for kidney disease?

The question that I get asked frequently by my kidney patients is are oats/oatmeal good or bad for kidney disease?

I will answer this question by breaking down different aspects of oats in kidney disease because when it comes to kidney diseases no one size fits all.

Every patients condition differs from one other. Therefore, dietary recommendations cannot be generalized.

Oats are a kind of grain that is eaten as a popular breakfast meal.

Back in the days, oats were mostly eaten in European countries but in recent years, due to increasing awareness of eating healthy, oats have found their way into the diets of Indian households as well.

Are oats good for high creatinine?

According to a study done on chronic kidney disease patients, eating oats did not show any changes in creatinine levels in renal patients.

Oats have a significant amount of certain minerals such as phosphorus and potassium. However, they can still be eaten by kidney patients.

The phosphorus present in the food does not get completely absorbed into the bloodstream. Therefore, when eating a meal that is naturally high in phosphorus, only a portion of it gets absorbed into the bloodstream because it is bound to phytates (an antioxidant) which do not allow the complete breakdown of the mineral in the digestive system.

However, foods that have been fortified (externally added) with phosphorus might get absorbed completely because they do not come from a natural source and are not bound with phytates.

Difference between oats and oatmeal

Oatmeal is a version of oats that undergoes processing to cut back on its cooking time when compared to whole oats which are not as processed as oatmeal and thus need longer cooking time to become fit for consumption.

Oatmeals also contain ingredients other than oats such as added salt and sugar. They may come in different flavors like chocolate, caramel, peanut butter, etc which involves heavy processing.

Different type of oats

There are different types of oats such as instant oats, steel-cut oats, and rolled oats. The difference between them depends on the average cooking time with steel-cut oats needing the longest and instant oats the shortest cooking time.

Whole Oat Groats

Whole oats are the result of harvesting groats (a grain), removing the hulls, and cleaning them. These kinds of oats take the longest time to cook as compared to others because of the minimal processing that they undergo. You can find these types of oats easily in grocery stores.

Steel Cut Oats

Oats are derived from a grain called groats. When the groats are cut into small pieces with sharp steel blades, the resultant product is called steel-cut oats.

The cooking time for steel-cut oats is shorter in comparison to whole oat groats but still longer as compared to rolled oats and instant oats.

Rolled Oats

Rolled oats are made when the groats are processed, steamed, flattened, and rolled to form flakes. Rolled oats can be cooked much more quickly in comparison to steel-cut oats because the absorption of liquid allows them to maintain their shape while cooking.

Instant Oats

When the rolled oats are steamed longer, you get instant oats. It is the most processed type of oats. Therefore, also the fastest to cook. It can be cooked in a few minutes. It is also available in the market in the name of one minute oats due to the minimal amount of time required for its cooking.

How oats are good for kidney disease?

Minimally processed oats can be an essential part of a kidney disease diet due to their rich nutritious content. Oats can aid in improving digestive and heart health. Oats are rich in a soluble fiber known as beta-glucan which signals the liver to remove LDL (bad) cholesterol from the blood.

People suffering from renal diseases may also suffer from digestive issues such as constipation. Since oats are rich in fiber, they can aid in preventing and relieving constipation.

It contains a soluble fiber that promotes the growth of good bacteria in the gut. This improves the overall gut health and prevents diseases that arise from the gut.

Oats are also rich in various vitamins and minerals such as vitamin B1 (Thiamine), B5 (Pantothenic acid), iron, zinc, magnesium, phosphorus, and copper. These are needed by the body to function without any deficiencies.

How oats can be bad for kidney disease?

A person suffering from chronic kidney disease should be careful while eating a highly processed and packaged type of oats. These may contain high levels of potassium and phosphorus that could put the kidneys of a CKD patient under stress.

A person suffering from stage 3 or 4 chronic kidney disease should try to avoid or limit the processed versions of oats and choose their oats in more of a natural form such as whole oats or steel-cut oats to avoid putting any additional burden on their kidneys.

Are Quaker oats and other instant oats okay to consume in CKD?

As I mentioned above, instant oats are the most processed version of oats. This means that they are the farthest from their natural form and the highest in minerals such as potassium and phosphorus. The excess of these minerals has to be excreted from the blood by the kidneys.

Hence, a person with CKD should eat instant oats in moderation and prefer steel-cut oats which take longer to cook but are healthier and minimally processed in comparison to instant oats.

When it comes to quacker or instant oats, make sure to look at the nutritional information behind the packet and choose the ones with the lowest sodium, phosphorus, and potassium content. Lowering sodium content also helps to keep your blood pressure in check.

Summary

In conclusion, oats can be a part of a healthy diet for a renal patient. Oats are nutritionally dense with many health benefits such as lowering LDL cholesterol, blood sugar, etc.

People suffering from CKD must be careful in their selection of oats and should prefer less processed ones like steel-cut oats because instant oats can be high on certain minerals which are not ideal for a CKD patient.

Oatmeal and Kidney Disease: How to Choose Oats & Prepare Them!

Oatmeal is a classic breakfast that Im sure you would love to continue enjoying with kidney disease.Or maybe youre trying desperately to find a way to prepare oatmeal that youd love to eat every morning!

Ive definitely been in that boat! I tried for years to love oatmeal but I just didnt because I didnt know what type of oatmeal to buy or how to prepare it!

Im Candace Mooney, a registered dietitian and board-certified specialist in renal nutrition. Im going to walk you through everything you need to know when choosing oatmeal for kidney disease and the best way to prepare it so its enjoyable but also protects your kidney health.

Lets start with the question everyone wants to know!

Is oatmeal good for kidney disease?

The short answer is YES!

Of course, there are special considerations when you have kidney disease when choosing any food to include in your diet.

Ill cover those quickly and then move on to the best ways to cook, prepare, and enjoy your oatmeal with kidney disease!

Special considerations for oatmeal and kidney disease

These are the main nutritional components I consider when determining if a food will fit into someones diet with kidney disease:

1. Carbohydrate and Fiber
2. Protein and Potential Renal Acid Load (PRAL)
3. Sodium
4. Potassium
5. Phosphorus

Lets go ahead and dive into each one of these a tiny bit deeper!

Carbohydrates and Fiber

Goal: It varies, just make sure you count it while balancing your plate (or bowl!).

When you are planning a meal, you want to make sure it contains some carbohydrates (carbs). Especially if you have diabetes, a good rule of thumb is to try to eat around the same amount of carbs with every meal.

The amount of carbs recommended could vary from 30 grams per meal to 90 grams per meal, depending on your medical history, height, weight, gender, activity level, and much more. A registered dietitian (like me!) can help you to calculate the ideal amount of carbs for you to eat.

One cup of cooked oats ( cup dry) gives you around 30 grams of carbohydrate. (1) It contains 4 grams of fiber to help you reach a goal of 25-38 grams of fiber per day. (1, 2)

Oatmeal offers a flexible base for your breakfast because you can pick the right serving size for your carbohydrate goal and you can add even more carbs (and fiber!) to it to get more variety and color in your meal depending on your toppings and mix-ins.

Goal: Plant-based and Negative Value PRAL

For most people with kidney disease, the goal is to eat less protein and to prioritize plant-based protein over protein from animal sources. (3)

The total grams of protein is one way to figure out if a protein source is a good fit for your menu; another consideration is PRAL (or, Potential Renal Acid Load).

Whats that, you say? The PRAL value of a food is determined by how much acid (or base) is produced by that food after you eat it.

The more negative the PRAL value of a food, the more base it makes during metabolism. The more positive the PRAL value, the more acid it makes. (4)

Why does the PRAL matter? When your kidneys arent functioning as well as they should, overall eating a positive PRAL diet can make your blood more acidic. (4).

The goal for people with kidney disease is to aim for as low of a PRAL value as possible. It is important to consider the average of all the food you eat for the whole day, not just a single food. This will help your body maintain a correct pH which benefits not only your kidneys but your entire body. (4)

One cup of cooked oatmeal has 5 grams of plant protein. This is considered low protein and leaves you lots of room to add more goodies that include some protein to your oatmeal! (1) This is, of course, dependent on your personal nutrition prescription.

Find a qualified renal dietitian to help you determine your personal nutrition prescription, including your own specific protein goals.

The PRAL for oatmeal is slightly positive, but much lower than animal protein foods. Oatmeal also gives you the opportunity to add lower PRAL foods like fruits and some nuts to it. This will decrease the overall PRAL value of this meal.

Sodium

Goal: 2,300mg per day

Aim for lower sodium in your food to help improve kidney health outcomes. (5) Luckily, oats are naturally low in sodium! (1)

The more processed your oats, the more likely there will be more sodium in them. Always be sure to check the sodium content of your oats!

Typically, people with kidney disease should shoot for less than 2,300 milligrams sodium per day. (5)

Goal: it depends, you may need to monitor it.

Some people with kidney disease may need to monitor the amount of potassium in their diet, especially if you have a history of high potassium in your lab results.

It is also crucial to have adequate amounts of potassium in your diet to help control your blood pressure. Limiting potassium unnecessarily could make it harder to control your blood pressure, causing more damage to your kidneys (6).

The good news is that oatmeal is naturally low in potassium so you can make it meet your potassium needs very easily by adjusting what you add to your oatmeal (1)!

Check with your renal dietitian or nephrologist to determine the right amount of potassium for you. If you dont have a renal dietitian, you can work with me or find another dietitian that specializes in kidney disease here.

Goal: avoid phosphate additives

Always read the ingredient list when you have the option! Avoid those pesky phosphate additives to help protect your bones and heart health (3).

Get into the habit of checking ingredient lists when you have kidney disease to help you avoid added phosphates in your food.

Look for any words that contain P-H-O-S in the ingredient list if you see these words, your food has added phosphates and it may not be a good fit to protect your kidneys.

Oatmeal is no exception to the rule! I have seen some oatmeal with added phosphates, but in general, oatmeal doesnt have any.

Is oatmeal a superfood?

Yes!

Eating oatmeal regularly has been linked to better heart health. Oatmeal works tolower LDL bad cholesterol by binding to it in your digestive tract. This means that instead of reabsorbing the cholesterol, you eliminate it in your stool. (7)

The fiber in oatmeal has also helped improve blood sugars in people with diabetes! (8)

Now that you know oatmeal can definitely fit into your diet with kidney disease and provide extra protection for you, lets walk through the different types of oats and how you can prepare them to enjoy them to the fullest!

Types of Oatmeal and Kidney Disease

If youre new to the oatmeal world (or even very familiar with it), it may seem confusing that there are several different preparations of oats you can buy.Ill clear up the difference between them for you now.

You may see your options at the grocery store are steel-cut oats, rolled oats, quick-cook oats, and instant oatmeal. What do all of these mean? And which one is best?

The difference between these is all in how the oat groat is processed before putting them on the shelf.Each one will have a distinct flavor and texture because of how it was processed but most will still have the same nutritional content.

The best type of oats for kidney disease will most likely be the type that you enjoy the most!

Steel Cut Oats

Lets start with steel-cut oats.These oat groats were simply processed by cutting or chopping them using a metal blade to make them look more round or more like rice.

They hold their shape well, and can be more chewy and hearty than the other varieties. They are also said to have a more nutty flavor. These oats also take the longest to cook.

A variation of these oats is Scottish or Irish oats. Instead of using a blade, these oat groats are stone ground into a similar shape but less uniform in size than steel-cut oats which gives a different texture.

Rolled Oats

Rolled oats are also called old-fashioned oats and they come in different thicknesses, too! The oat groats are steamed during processing and then pressed to be flat. They look more like flakes of oats.

Rolled oats cook faster than steel cut oats. They still hold their shape well but absorb more water making them a little less chewy.

You can use rolled oats as a hot cereal, baking, and overnight oats. They are the most versatile version of oats.

My personal favorite rolled oats are Bobs Red Mill Extra-Thick Rolled Oats*. They are able to hold their shape and provide some chewy texture to your bite without getting too mushy.

Quick Cook and Instant Oatmeal

Quick cook oats are processed in the same way as rolled oats but steamed longer and pressed thinner to make them cook even faster for you at home.

You guessed it! Instant oatmeal is steamed even longer and pressed thinner to instantly cook for you at home!

These oats dont hold their texture as well and become mushy but they can help you out when youre in a hurry!

The other drawback to instant oatmeal is that it can sometimes contain preservatives like sodium and/or phosphates or even added sugar so always check your nutrition label and ingredient list with these types of oats, especially!

How to Prepare Oats

There are several variations of oatmeal that would make a perfect breakfast for someone with kidney disease!

Two classic oatmeal versions are either hot or cold.

Lets dive deeper into each of these versions!

Hot Oatmeal

The classic oatmeal! Hot oatmeal has been around forever it seems!

The most simple version of hot oatmeal just includes water.

You boil oatmeal and water on the stove, reduce heat, and simmer until the water has been absorbed and your desired texture is reached!

Each type of oatmeal above varies in the amount of time to simmer so its best to follow the instructions on the package. Who knew?!?

Overnight Oats

Overnight oats have been gaining popularity in the last few years and are my personal favorite way to enjoy oatmeal!

You basically mix all your ingredients the night before youd like to eat it and let it soak for at least 4 hours. The great thing about overnight oats is you can batch-prep them for the week and their texture stays consistent until the end of the week!

My favorite recipe comes from my mom! Its our best copycat version of a breakfast she ate on Vikings Blue Danube River Cruise.

Milk Choices

You could make your hot oatmeal with milk, instead of water, to get a fuller, creamier oatmeal.

Overnight oats are always made with some sort of milk. Plant-based diets are often recommended for kidney disease to improve health outcomes so you may want to choose a non-dairy milk.

Some kidney-disease-appropriate, non-dairy milk examples include almond, soy, cashew, rice, coconut, and oat milks.

If you have a history of kidney stones, you may want to choose dairy milk for the natural calcium source and avoid high oxalate milks like almond and soy milk. Learn more about oatmeal and kidney stones.

Also, make sure you read the ingredient list in any milk you choose because they can be notorious (a-hem oat milk) for adding potassium and phosphates!

Toppings

Now this is where it gets fun! As we talked about earlier, you have extra room to add carbs, protein, potassium, and fiber to your oatmeal to make it even more delicious.

Nuts and Seeds

Nuts and seeds can get you some extra protein and minerals in your oats! Some popular options are mixing 1-2 tablespoons of nut butter into your oats.

Hemp seeds* can be mixed in to give you a rich, nutty flavor with the added benefits of omega 3 to increase oatmeals heart-healthy profile even more!

Chia seeds* also contain omega 3s and can give your oatmeal a fuller feel by making it a little more gelatinous.

Coconut shavings* are a great way to add calories and change the flavor profile of oatmeal, too!

Fruit

Adding fruit is a great way to add a natural sweetness and increase flavor, fiber, and vitamins in your oats!

You can add chopped apples or pears to your hot oats or shred them to include in your overnight oats! These are great low-potassium options if you need to watch potassium in your diet.

Berries are another great way to add fiber and color to your oatmeal. You can use fresh berries or even have a bag of frozen berries in your freezer to add to your hot oats.

Raisins can also be added to your oats as youre cooking them or soaking them overnight for a burst of flavor!

You can really let your creative juices flow when deciding how to add fruit to your oats! (hehe)

Spices

The most popular spice to pair with oatmeal is cinnamon, and for good reason! It adds a lot of depth to oatmeals flavor.

Other popular spice options to elevate your oatmeal include pumpkin pie spice, nutmeg, vanilla, ginger, and black pepper.

My personal favorite addition to hot oatmeal is a garam masala blend*! Mix in some blueberries and viola!

And the best part is most spices are perfectly fine to eat on oatmeal with kidney disease!

The sky is really the limit!

The Verdict: Oatmeal and Kidney Disease

Oatmeal is a great meal option for kidney disease.

You should definitely check the nutrition labels and ingredient lists of the type of oatmeal you choose (especially if you like quicker-cooking oats like instant oatmeal).

Your goal is to avoid extra sodium and avoid potassium and phosphate additives.

Oatmeal provides a great canvas for adding your favorite flavors to make it delicious!

Add fruits, nuts, seeds, and different milks to improve oatmeals nutrition (and flavor!) profile for even more benefits for kidney disease!

Now go have fun with your oatmeal! (and share your favorite varieties below!)
