Oatmeal: Good or bad?

You've heard it before: oatmeal reduces cholesterol. Oatmeal producers have obtained permission from the FDA to use a cholesterol-reducing claim. The American Heart Association provides a (paid) endorsement of Quaker Oats.

I've lost count of the times I've asked someone whether they ate a healthy breakfast and the answer was "Sure. I had oatmeal."

Is this true? Is oatmeal heart healthy because it reduces LDL cholesterol?

I don't think so. Try this: Have a serving of slow-cooked (e.g., steel-cut, Irish, etc.) oatmeal. Most people will consume oatmeal with skim or 1% milk and some dried or fresh fruit. Wait an hour, then check your blood sugar.

If you are not diabetic and have a fasting blood sugar in the "normal" range (<100 mg/dl), you will typically have a 1-hour blood glucose of 150-180 mg/dl--very high. If you have mildly increased fasting blood sugars between 100 and 126 mg/dl, postprandial (after-eating) blood sugars will easily exceed 180 mg/dl. If you have diabetes, hold onto your hat because, even if you take medications, blood sugar one hour after oatmeal will usually be between 200 and 300 mg/dl.

This is because oatmeal is converted rapidly to sugar, and a lot of it. Even if you were to repeat the experiment with no dried or fresh fruit, you will still witness high blood sugars in these ranges. Do like some people and pile on the raisins, dried cranberries, or brown sugar, and you will see blood sugars go even higher.

Blood sugars this high, experienced repetitively, will damage the delicate insulin-producing beta cells of your pancreas (glucose toxicity). It also glycates proteins of the eyes and vascular walls. The blood glucose effects of oatmeal really don't differ much from a large Snickers bar or bowl of jelly beans.

If you are like most people, you too will show high blood sugars after oatmeal. It's easy to find out . . . check your postprandial blood sugar.

In past, I recommended oat products, specifically oat bran, to reduce LDL, especially small LDL. I've changed my mind: I now no longer recommend any oat product due to its blood sugar-increasing effects.

Better choices: eggs, ground flaxseed as a hot cereal, cheese (the one dairy product that does not excessively trigger insulin), raw nuts, salads, leftovers from last evening's dinner.

    this is somewhat surprising, however, not completely shocking. Carbs are sugars, and I've known for quite some time that Oats are loaded with carbs. I never thought of the effects of the oatmeal though, I've always seen it as a positive and healthy way to start off the day...

    I guess that view has changed now.. I'll be consuming a lot less oatmeal.

    Does this also include whole unprocessed (cooked) oats?

    Those, along with wild rice are the only grains our cardiologist said are okay, and only so long as they remain whole, unprocessed grains.

    Oatmeal- what a pickle it's gotten itself into.
    Healthy, healthy oatmeal is all you read about until one checks their blood sugar after eating it. Mine went from 82-179 in 45 minutes.
    No honey or raisins or anything added- the same spike.
    For me, eating oatmeal is like having an IV drip of straight sugar into my blood stream.

    Oatmeal has now been relegated to  food for my mealworms who in turn are snacks for my bearded dragon.

    Darn, I like oatmeal!!

    ??? I eat 1/3 cup (add water) of Oatbran for breakfast everyday with berries - 1 and 2 hour blood sugars are about 100. ( or a serum level of 89)  That is a carb load of 16 for the oat-bran - add the berries and it is 20. Not a lot for the big meal of the day for a large guy.

    I'm not sure everyone has the same problem - it is a matter of amount, not 'just' the type of food.  I am much more careful to eliminate fructose containing sugars.

    You lump all "oatmeal" into a single category.  Is there a difference between instant oats vs. rolled oats vs. steel cut oats?

    I sometimes cook steel cut oats overnight, and then add some whole raw milk at the end.  I eat it with walnuts and cinnamon.  I would assume that the fats and cinnamon decrease the blood sugar spike?  Is this the case?  I would appreciate your comments

    Dr. Davis,

    I am not a cereal eater of any sort, and never eat oatmeal or oat bran.

    A typical breakfast for me might consist of 2 whole pastured eggs + vegetables and some coconut milk with around a 1/2 teaspoon of cinnamon mixed into it. Would 1 serving of oatmeal added to something like that be as likely to trigger higher readings (relative to each of the states you mentioned)?

    NOTE: I'd try it out and test with a glucometer, but I dislike the taste of oatmeal and oat bran, so it makes that avenue a moot point.

    Thanks for this information, I am glad to see you are not recommending oat bran anymore.  Recently I tried 2 tablespoons of oat bran a day for 4 days for ldl cholesterol reduction.  As a result I gained 4 pounds and experienced a resurgence in my joint pain (and cravings) which had been previously greatly reduced by going grain free.  It took about 4 weeks to loose that 4 pounds.  No more 'healthy' oats for me!  Randy.

    I have been eating quick oats for breakfast every day for fifteen years, lately adding cinnamon, flaxseed meal, and blueberries. Is it enough time to make me a diabetic? I typically walk for 25 min one hour after breakfast to catch the train, so it is difficult for me to check my blood sugar during this time. Is oat meal consumption harmful even in this combination with physical activity?

  • Pascal

    I think your comment that oatmeal will raise sugars in non-diabetic people to over 150 is a little exaggerated. I had a fasting sugar of around 100 and 1 hour after one serving eating Old Fashioned Quaker Oats my blood glucose got to 126. While this is not an ideal glucose level it is nowhere near the 150 you are referring to. I had some other members (non-diabetic) of my family try the same experiment and none of them came close to 150.

    I switched to a non-wheat diet, moderate carb diet at the beginning of the year. For breakfast I stopped eating sugar-packed cereals and ate Old Fashioned Quaker Oats instead. My triglycerides dropped like a rock from almost 200 to around 60. My HDL went from 35 to about 60.

    I do agree however that people who are insulin resistant may need to avoid oatmeal as it does contain a plenty of carbs but comparing oatmeal to candy bars in the context of blood glucose response is really stretching things.

    Tons of carbs = raised blood sugar. I meet a lot of people eating oatmeal believing it is healthy. I am from Sweden and we have a long, long tradition of oatmeal.

    The grain industry has been sponsoring Swedish athletes for a very long time.

    Apparently, kids who get into sports get a brochure, from sponsored by one of the biggest grain producers in Sweden, loaded with propaganda about how athletes MUST eat a lot of carbohydrates.

    Fortunately there are more and more athletes breaking away from traditional diets. One of the main reasons being, that top athletes get sick a lot. Björn Ferry, who won a gold in Vancouver, is on a low carb diet. No oatmeal whatsoever for him.

    I've been testing my blood sugar after meals and what I find is a little steel cut oats, a little wild rice, a little beer doesn't raise my blood.  A lot of any of these, on the other hand, does. It seems more related to quantity than to which carb.

  • Jen

    3/12/2010 2:11:12 PM |

    I have heard, "...eat fats with your carbs..." to keep one's insulin livels from spiking so much.  I choose butter or cream from grass fed cows.
    Have not checked insulin levels after fat or no-fat old fashioned oatmeal to see the differences.
    It's worth testing on myself as my fasting glucose levels are in the low range.

    Now they even have "organic" oat meal to make it super healthy! The madness never ends.

    My 4.5% butterfat whole, unprocessed jersey milk does not cause my blood sugar to spike, neither does butter, yogurt, cream or cheese made from it. But I am non-diabetic. Measuring blood sugar after drinking pasteurized store bought milk (~3.2% butterfat) does raise it about 10 more units (110) instead of 100. WAPF says the heating makes lactose digest quicker.

    I didn't hear anything that oat bran can't bring down LDL, only that one has to be mindful of the BG issues concerning it.

    I'm mindful as I'm IGT, but don't seem to have issues with oat bran and my 1h ppg readings.  They've never been above 6mmol/L, and more than likely be in the mid 5s like anything else I've tested with the expection of food containing starch.

    For the record, I use water and don't load it with fruit.

  • Dr. William Davis

    3/12/2010 7:25:32 PM |


    Excellent point.

    Portion size is indeed a crucial factor: The greater the quantity of carbohydrate, the greater the impact on blood sugar.

    Therefore, many of us can get away with small quantities of oatmeal, cream of wheat, or other carbohydrate (at least from a blood sugar standpoint). Most of us cannot deal with any more than a little. Some cannot deal with any at all.

    I found that a bowl of oatmeal, with cream and two boiled eggs was enough to shoot my blood sugar from fasting 110 to 160+.  Now, I clearly have issues since my fasting is a bit high, but my conclusion for myself was, fat and protein didn't stop the carbs.  I do fine with a small bowl of full fat strained yogurt and walnuts though.  And eggs, veggies, or a small steak...

    I've been wondering...is bacon REALLY bad for you (like most people say), or is it okay? I've been eating a relatively low-carb breakfast of poached eggs and bacon, and a small serving of fruit, but I'm concerned that the bacon is a bad choice (although I love it, and it leaves me satiated until lunch). Any insight?

  • Anonymous

    The effects of carbohydrates on blood sugar levels is represented by the glycemic index. The glycemic index is determined by feeding various people a certain food and measuring their blood sugar level multiple times over a period of several hours.

    Oatmeal has a fairly low glycemic index (around 50 I think), which means its effect on the blood sugar level of a regular person is low.

    The glycemic load of the whole meal containing oats can be even lowered by mixing it with some other very low GI food such as nuts.
    A half a cup of oatmeal with 1 oz of walnuts cannot be much worse than fried eggs and bacon everyday, can it?

    Okay, y'all have prodded me to check my blood sugar.  Despite being a diagnosed type 2 diabetic for over 20 years, I've relied on the A1C test and avoiding processed foods.

    Today, fasting level = 90

    After a huge bowl of old fashion slow cook oatmeal (1 cup dry uncooked), plus raisins and MCT oil, I tested 126 immediately after eating.

    20 minutes postprandial = 120 (after 15 minute walk)

    1 hr postprandial = 136

    2 hr postprandial = 71 (after another 15 min walk)

    Normally I eat oats/groats but I'm visiting my mom now, and don't have access to groats.  In my opinion, oats/groats is metabolized more slowly and is more nutritious.

    I have a lot of Scottish blood and the Scots have thrived on oats for millenia.

    The unasked question is, what constitutes 'repetitive' consumption of oatmeal? Breakfast every day? Twice a week? Or what?

  • Raine Saunders

    6/29/2010 2:42:55 PM |

    If you were to soak the oats in an acidic medium overnight (such as kefir, yogurt, apple cider vinegar, whey, or lemon juice), and then eat it with real, raw milk and a bit of real maple syrup, it would be much healthier for you. But I wouldn't recommend eating it every day because this habit of eating grains too often, even when properly prepared can still lead to health issues. Grains that are not traditionally prepared as our ancestors did lead to many problems like obesity, heart disease, cavities,digestive disorders, candida overgrowth, Crohn's Disease, Leaky Gut, hiatal hernia, diabetes, and much more.

    What a fantastic post! It's about time someone started cracking down on so-called "good carbs." My husband is a cardiologist too, has been preaching this for years and getting the very same "Huh?" reactions. The credo is our house is: CARBS & SUGAR ARE THE SAME THING, because all carbs metabolize into sugar. "Good" ones may take 30 minutes longer, but they'll still become sugar faster than your body wants it. Try to stick to just low-sugar fruits and veggies...and thank you, doctor, for helping to clear the blizzard of misinformation out there. Here's our non-profit site if you're wondering who wrote this: http://tinyurl.com/b8vjja

    This blog usually delivers scientifically sound nutritional information. This particular blog publication is the exception. It gives information without a single reference. It is daunting to write that oats will make a spike in your blood levels without any further information. Oat porridge is known to lower the glycemic response to a load of carbohydrates. You are missing important information about the fiber content. It IS a good source of fiber, both soluble (beta-glucans) and insoluble when eat as a whole. Additionally, is proven to lower serum LDL levels and increase HDL. Of course if you use a oat product full of sugars or in the wrong presentation/processing the history is quite different.
    Much more can be found if you type Oats and glycemic index at Pubmed.

    I'm extremely grateful for this information. For years I have conscientiously followed the type of diet that is widely promoted as being healthy, including whole grain oatmeal. My cholesterol numbers have been stellar, aside from the total sometimes being below the reference range. My fasting glucose has been normal. I was shocked to learn in follow-up after a severe foot infection that my peripheral arteriosclerotic situation is not so stellar. In view of the information on your blog I bought a glucose monitor. My blood sugar an hour after a large bowl of slow-cooked oatmeal with no fruit, milk, sugar, or other additions = 150!

    Oat Bran, I have read that Oat Bran is good for you as it is high in fiber and helps to clear fats from the blood.  I am not sure about the refinement as to whether fine ground or medium ground is best?  I have read other medical materials that support using Oat Bran for cereal, muffins, or even as bread crumbs for baking.  This can be confusing as I had once believed Oat Meal was good for you and a heart healthy diet.  Does OAT BRAN fall into the same catagory as OAT MEAL?

    The 'healthy breakfast myth'. Humans don't need any breakfast or lunch if they eat a proper diet. The body has ample fat stores to provide our energy for the day. Most hunter-gathers don't eat any breakfast and lunch is rarely anything other than a small snack. They start eating mid-afternoon and nibble away for most of the evening.

    The only reason westerners need breakfast or lunch is because they are carbohydrate addicts. If you switch to a VLC (<20g/day) diet you won't get hungry before 4pm once you adapt. In fact once adapted to a VLC diet you can effortlessly go 2-3 days without food and not have any problems.

    We eat oatmeal on occasion and have no problem with high blood glucose probably because we add enough butter, cheese and cream so that the calories from dairy fat far exceeds the calories from the oatmeal. And we have no insulin problem from consuming a lot of butter.

    We are not concerned about cholesterol levels. The only reason we eat oatmeal is because it seems to help regularity.

    How does the article justify going from heart healthy benefits to affects of oatmeal for diabetics?
    Just because a food has to be eaten with caution by diabetics does not mean it is not beneficial as it has been determined.
    It is the same as with any food: Read The Label. Yes, oatmeal is a grain, and therefore has carbohydrates (an essential food). So, add protein if you have blood sugar issues or eat it less often, or in smaller quantities!
    Any whole grain will have the same issues. And why would a diabetic add sugars or fruits to a carb food??? Come on!
    For heart benefits, lowering harmful cholesterol, it is one of the whole grains that is important to have in your diet. Profiling it as a diabetic issue is just not fair.

    Hi Doctor Davis,
    Can't disagree that oatmeal does indeed contain a fair amount of (complex) carbs. However, according to a study published in the American Journal of Clinical Nutrition (link below), when it comes to insulin demand generated by different common foods, oatmeal ranks surprisingly low while some foods not normally associated with a high insulin response don't fare as well as we would think. http://www.ajcn.org/content/66/5/1264.full.pdf+html

The findings also showed that the diet led to an impaired ability to form new blood vessels in tissues deprived of blood flow, as might occur during a heart attack."

    I like oats so when I came across this blog I was interested to read about oats being taken off the Dr.s' recommend food list
    due to spiking bloodsugar levels. I'm in this category described in the blog post - "If you are not diabetic and have a fasting blood sugar in the "normal" range (<100 mg/dl), you will typically have a 1-hour blood glucose of 150-180 mg/dl--very high."

    I decided to perform an informal blood sugar profile of my typical oats breakfast meal under the following test conditions:

    Test device: Accu-chek Integra

    50g - Quick Oats Homebrand Woolworths Australia
    125g - 1% low fat milk
    50g Mixed Frozen berries (raspberries/blackberries/blueberries/cranberries)
    Total Kcal from meal = 271

    No other food or drink during 2 hour testing period.

    Testing period: Initial measurements at morning fasting but after gym workout (T0) then every subsequent 30 minutes for 2 hours

    T0: 91.8 mg/dL
    T0+30: 136.8 mg/dL
    T0+60: 120.6 mg/dL
    T0+90: 108.0 mg/dL
    T0+180: 104.4 mg/dL

    The peak 136.8 mg/dL at the 30 minute mark is within the  acceptable range post meal and well below the 150-180 range suggested in the blog.

    I will try slow oats next time - Kcal content is the same but the oat flakes are larger which suggest slower glucose release.

    Everyone responds to food differnetly so YMMV.

    My husband was recently diagnosed with diabetes. Oatmeal is listed as a low glycemic index food, so we thought it would be fine for him to enjoy this once in a while. Unfortunately, his last bowl of rolled oats with no sugar and only a dash of milk caused him to have blood sugar in the mid 200's for FOUR HOURS afterward.

    We are discovering that we have to forget what the industry says and base our food choices on a case by case basis. Some foods cause him to spike, and other foods that you would think would be terrible (like potato chips) don't cause a glucose spike at all. It's certainly a learning curve.

    Hi i have been finding the same thing with oat meal. Im on my second day of testing. after eating 3/4 cup old fasion quaker oats, 1/4 cup raisins, 2 tbs pecans 1 1/2 tbs flax 1/8 tsp cinnamon, 1/2 cup skim milk, and 1 tbs of real maple syrup. 1st days numbers where. 110 just before eating. 189 1hr after start of eating. 100 2hr after, 78 4 hrs after. 2nd day. 102 just before eating, 172 1hr after start of eating, 84 2hr after. My question would be. Is the BS spike after eating enough to kill off the Beta Cells in the Pancreas? Also why do I sustained lower BS lvl for hrs after eating the oat meal? Only meal so far that I get the Lower numbers for hours after.

    I'm in this category described in the blog post. Now, a study led by a scientific team at Beth Israel Deaconess Medical Center (BIDMC) provides some of the first data on this subject, And why would a diabetic add sugars or fruits to a carb food??? Come on!

    I eat no grains and my trigs and HDL are better then your numbers.  The benefits of grains are wiped out by the phytates.  It is a waste of calories.

    More internet BS....  Oatmeal is the last thing you want to eat if your a diabetic. I do clinical test for a doctor and oatmeal is a no, no for diabetics... Eggbeaters, bacon and coffee.  Very little rise in sugar..

    I haven't been diagnosed as diabetic, but I do have a sensitivity.  If I eat a medium or large meal that includes bread, I practically go to into a coma and must sleep for 30 to 45 minutes.  Yet, I've been eating oatmeal for breakfast for the past year and my cholesterol went from "above acceptable" to the low range of "acceptable".    All my cholesterol levels improved dramatically and are in the most perfect range they can be in.  Though I  don't check my blood sugar, I can eat a bowl of oatmeal at any time and I never have that spike that puts me to sleep.  So for me, it's been a God send.  It's one of the few "treats" I can eat without any noticeable adverse affects.
