Just two days of oatmeal cut bad cholesterol by 10%

Fiber is the ultimate nutritional power tool.

Not only does fiber reduce cardiovascular mortality by 26% (by cutting cholesterol), surprisingly enough, fiber even reduces your risk of cancer by 22%: https://www.empirical.health/blog/dietary-fiber-reduces-all-...

(Oatmeal is high in fiber, among other things, which I think is part of what's going on here.)

Oatmeal is extra special because of it has high amounts of beta glucan, a soluble fiber.

Overnight oats are just normal oats left in liquid overnight to skip the cooking step.

What processing were you thinking of? If anything they are less processed than normal oats since they aren't cooked.

Wait, how does fiber cut cholesterol?

The article is a little densely worded.

by happytoexplain

3/1/2026 at 3:06:09 AM

iirc, from older articles, which differ from this nice result, bile acids contain cholesterol(s) and they're generally reabsorbed in the intestines, so the fiber is conjectured to bind with some before reabsorption, expelling the bound fraction of circulating cholesterol in feces.

this result in the paper is very interesting in the conjecture is that the gut microbiome is altered in a beneficial way, and that the effect (with the resulting lowering of cholesterol) persists for weeks after even 2 days of oats.

by jjtheblunt

We know almost nothing about how digestion works, but fiber has the added benefit of lining your intestines, preventing the absorption of some nutrients. It also helps push things through, so they spend less time sitting around being absorbed.

I'll recommend starting here https://nutritionsource.hsph.harvard.edu/soy/ (link of studies at the bottom of the page)

Takeways related to parent:

- "cardiovascular mortality ": > eating approximately 50 grams of soy protein a day (no small amount as this translates to 1½ pounds of tofu or eight 8-ounce glasses of soy milk!) in place of animal protein reduced harmful LDL cholesterol by 12.9 percent. [1] Such reductions, if sustained over time, could mean a greater than 20% lower risk of heart attack, stroke, or other forms of cardiovascular disease.

- "risk of cancer": many studies shows breast and prostate cancer reduction, but that is probably more related to isoflavones (Phytoestrogen) than fibers.

Oh boy. Now we’re entering the fiber era. We’re just leaving the protein era. Before that it was the intermittent fasting era. Before that it was the keto era. The low fat era was probably a few before that.

I hear about fiber constantly all of the sudden. You might be right about it, but how do we know it’s different than. All the past nutrition tends?

by buzzerbetrayed

3/1/2026 at 6:43:34 AM

Idk about cholesterol, fiber is well known to be very healthy. Same for protein.

Losing body fat will often have the biggest impact by far if one is overweight, though. It also stabilizes blood sugar and has a lot of benefits in general.

It is funny how you can break diet/nutrition into generations like this.

I think the trends are a reflection of poor education. Fiber/protein/whatever being important components of a diet isn't new information. But the information is new to folks that never had nutrition explained to them.

by rybosworld

3/1/2026 at 4:00:25 AM

I feel like we're due for something really ridiculous next. I've been paying attention to macros, fibre, salt, and having a reasonably varied diet for years; we've done salt, fat, carbs, protein, and now we're doing fibre.

"Eat a varied diet" seems boring but maybe those influencers selling pills made from 500 vegetables were ahead of the curve all along.

by strken

3/1/2026 at 4:09:33 AM

It would probably be better to just eat all those different vegetables as part of actual meals to get a varied diet, rather than in pill form.

I was under the impression that more protein and less salt/fat/carbs are still kinda the trend? If more fiber gets added to the mix I guess it is essentially telling people to eat more plants, thus leading to more varied diets overall.

by rmast

3/1/2026 at 3:39:40 PM

Because the trends are bullshit and nutrition is just not that complicated.

The trends are a strange type of nutrition entertainment for people to read and then ignore in practice. There is some kind of psychological comfort in the knowing you can switch to oatmeal next week while gorging yourself at the Cheesecake Factory.

Oatmeal is good for you. News at a 11. We have known this for at least that last 50 years.

I routinely used to eat an oat based breakfast, and would then feel as though my blood pressure and energy levels were seesawing around for the rest of the morning. Turns out I have celiac disease with sensitivity to the protein in oats.

by dtj1123

I'm somewhat gluten sensitive (tends to make my psoriasis flare up) but used to have gluten-free oats for breakfast. Then the porridge seemed to increase my uric acid levels, leading to gout attacks, so I've had to stop eating them (oats are usually classified as mid-level purine content and thus should be only eaten once or twice a week for those prone to gout).

Steal-cut oatmeal made in Insta Pot is the best thing in the world. I do 2.5 to 1 ratio. It is important to not let the steam out. It takes about 30 minutes plus another 10 to cool. Set it and forget it. Add raisons and cinnamon at the end. Or, let freshly minced ginger steep with some orange zest.

by dataviz1000

3/1/2026 at 3:38:41 AM

I make it on the stove top. It also takes 30 minutes to cook and 10 to cool. My ratio of water to dry oatmeal is 3 to 1 by weight in grams and I mix in honey after it's done.

I did this after it was first posted. My cholesterol is great, but it is a simple enough intervention, I mostly did it for the lols.

Not terribly difficult, you never feel hungry. The worst part was how sore my jaw felt from the excessive chewing of the bulk mass. Which is funny for something so mushy, but my instinct was to chew it a good amount. Also, it is a lot of fiber. Feel like the effect might just have to do with cleaning out every surface of my digestive tract.

by 3eb7988a1663

I did it as well, 2 days of oatmeal (plus some chicken and toppings) and then oatmeal most days just one meal. Didn’t expect much…my cholesterol dropped 25% over a period of 3 months. One data point, will do another 2 days and see in another 3 months.

by mrbombastic

Oatmeal reliably spikes my blood sugar. Not as much as many other carbs, but enough that I avoid it. Each time an insulin resistant person eats it, it causes a little more permanent damage.

Four out of ten US adults are insulin resistant.

I have no idea how to balance the blood sugar damage with the cholesterol damage.

by delichon

3/1/2026 at 2:40:43 AM

Not all oatmeal has the same effect on blood sugar. Steel cut oats are absorbed more slowly than instant oats. Toppings on your oatmeal also affect blood glucose in non-linear ways, the same as any other combination of foods.

by david-gpu

3/1/2026 at 2:40:42 AM

I would think the type and preparation would play a significant role. There's steel cut (which can be made soft or "chewy"), firmer "old fashioned", and the quick dissolving mush that is one-minute.

glycemic index of steel cut is low, whereas large-flake is medium-high, and instant oats are high. Though you have to account for load.

My approach is to have a modest amount and increase the nuts and chia mixed with it, alongside berries and yogurt.

by lanfeust6

3/1/2026 at 2:58:35 AM

Try oat groats, this will have the lowest GI. You can cook them like rice, even in a rice cooker, using the same technique ... for a firmer result use less water and cook for less time. You can start off with roughly 1:1 ratio of oat groats to water. I do .75 cups oat groats to 1.25 cups water.

by clumsysmurf

3/1/2026 at 3:55:10 AM

Use thicker oats, obviously. Also, add some ceylon cinnamon powder to it. Additionally, if you can tolerate it, also add ground fenugreek powder to it to further offset the absorption.

by OutOfHere

3/1/2026 at 2:50:57 AM

Oatmeal has become my favorite breakfast by far. It's delicious and never seems to never give me the "crash" that people describe with other carbs (probably due to it's low GI). Very easy to blend them into my protein shakes after a morning workout too.

i eat an apple with a teaspoon of pistachio butter (sometimes two) for breakfast. If I am still hungry, I eat 150g of blueberries with some vegan organic protein powder (2 teaspoons) and cottage cheese.

How can I tell if oatmeal would have more fiber?

I also eat basically an entire romaine earth at lunch and cooked veggies at dinner.

Fiber is definitely the only things that makes me full without making me fat.

I have high cholesterol, have had for more than a decade. Was on a statin, they didnt help. Doubled them, they didnt help. Changed my diet radically, lost 25 lbs (I was a little overweight, but not bad), ate full medeteranian diet and did everything I could, my numbers didnt budge. Changed to a stronger one and within two weeks my numbers were perfect.

I believe for some of us its purely genetic.

by netcraft

3/1/2026 at 5:10:27 AM

There are some people who just have high cholesterol but none of the other risk factors. I'm one of them. I did a calcium score on my heart, and it came back clean. The cardiologist basically said my cholesterol is just part of who I am, and it's not causing problems.

If you're similar to me, you might want to get a second opinion. There are different kinds of LdL cholesterol, and the small, dense particles are the ones that cause blockages. Big puffy ones don't. I have mostly big puffy ones, but classifying them is a different test that has to be special-ordered.

I also have a very low resting heart rate, exercise regularly, have a high VO2Max, and have a healthy diet. So the claim that I was at major risk of a cardiac episode just didn't pass the smell test. If it wasn't for those things, I probably wouldn't have asked questions when my doctor said I should go on a statin.

by EPWN3D

3/1/2026 at 5:37:01 PM

unfortunately im not in the same situation. I have a high incidence in my family, my calcium score wasn't clean (especially for someone my age) and my vo2max isnt the best either. Though my many stress tests have always been fine.

I don't think im in terrible shape right now, but looking ahead 10 to 20 years, without medical intervention I probably would be.

My LDL is stuck between 145 and 155 permanently. Same for my mom and aunts. Oatmeal, exercise, etc. doesn't help.

I'm still young so my doctor isn't terribly concerned, but in 10 years I'll probably have to be on statins.

by dralley

3/1/2026 at 9:46:20 PM

You should question this and advocate for yourself. The important number is total lifetime exposure to LDL (actually apoB, but doctors aren't routinely testing that yet). The arterial damage is cumulative. You shouldn't wait until you are at high risk of cardiac events to take action. The time to slow down the progression is now.

I'm just replying based on taking your comment at face value. LDL of 150 is very high and living with that for many years is very damaging. Obviously it's something between you and your doctor, I'm just encouraging you to consider and get reasoning from your doctor about whether this approach is really best for your health.

by WarOnPrivacy

3/1/2026 at 3:36:41 AM

If you make plain oatmeal with less water so that it is thick rather than runny, it can be treated like a side dish like mashed potatoes or polenta in a savory meal. It can be a bit odd at first for people who are used to thinking of oatmeal as a sweetened food but it's something one can get accustomed to quickly and avoids the downside of consuming extra sugar.

by ThrowawayP

3/1/2026 at 7:10:25 AM

In my opinion oatmeal is better as a spicy-savory rather than a sweet dish. You could add black pepper and a bit of salt to it and maybe a hot sauce for even more flavor. Montreal steak spice also works well.

Could take it to the next level with green peas, diced carrots and other things.

In fact once you go savory, you'll never go back. Sweet oatmeal grosses me out.

by Lord_Zero

3/1/2026 at 4:11:26 AM

Cottage cheese is quite low in fat for cheese. The one at my local supermarket is 11.3g protein, 2.4g fat, 6.3g carbs, and it's not a diet version.

It's still very salty and most of the carbs are in the form of the sugar lactose, I'm not really recommending it as a health food, it's just comparatively low in fat.

I soak mine overnight with nuts, in water and a tsp of yogurt, then drain/rinse off in the morning. Steel-cut if I'm cooking it stove-top, large-flake if I'm just microwaving the oats. Serve with the nuts, alongside berries and whatever else.

Years ago I'd sometimes go over-the-top with homemade kefir, cocoa nibs, lemon zest. I stopped the kefir habit not so much because of the hassle but because I didn't want to consume that much volume of dairy every day. I get enough lactic acid from kimchi, and protein from other sources.

I consume these so often for breakfast that I've calibrated the "core" meal many times. Personally I think the optimal amount is less than you would think, to make room for other ingredient pairings like berries, nuts and fermented dairy.

It's not the laziest method but I like soaking them overnight. Without being too fussed about phytic acid in a balanced diet, soaking still improves digestibility and nutrient absorption.

by lanfeust6

3/1/2026 at 7:42:01 AM

Honestly? It's advertising, not biology.

All starchy foods make cholesterol go up, while all animal proteins make it go down, since digesting them consumes LDL. People only campaign against this scientific evidence because there are so many of us in the world, too many, and there isn't enough animal protein for everyone, especially if you focus on economically profitable production instead of distributed subsistence production wherever possible.
