My point was I've eaten cereal most of my life, in the form of rolled oats or steel-cut oats (and now increasingly using oat groats), not the sweetened stuff that comes in little packets, and recently been happy to branch out, inspired in part by memories of breakfast in Japan.

Maybe it's a regional thing, but "breakfast cereal" is exclusive of "oatmeal" where I'm from (despite oats being a cereal grain). Breakfast cereal is crunchy and served cold, neither of which applies to oatmeal (even overnight oats are cold but not crunchy).

Why wouldn't you prepare and serve oatmeal cold?

Overnight oats / bircher muesli is served cold and requires no cooking. The time aspect is to give the oats time to absorb the liquid - cold oats swimming in freshly poured milk isn't the most appetising way to eat oats.

Of course you can "speed up" the process by blending them into a smoothie.

You can (overnight oats), but it's still not crunchy.

If you toast the oats first to make them crunchy, it's no longer the dish called "oatmeal" (which is a porridge) but now it's a kind of granola, which can be used as a breakfast cereal.

It contains protein and is low sugar (unless you cover it in honey and fruit everyday, but even then, at least you’d be getting some actual nutritional value)

I think the point was that oatmeal IS a cereal

Oats are a cereal grain.

Oatmeal is cereal; and it comes in a range of sugariness, as does the kind of cereal intended to be eaten cold.

I can't really tell what you were thinking here.

Oatmeal is nutritionally identical to cereal for the obvious reason that that's what it is.

Here's the nutrition sidebar for Quaker Oats rolled oats versus Cheerios:

Cereals are typically more processed than oatmeal (especially when we talk about uncut oat meal). If we talk about instant oatmeal vs cereal, then I don't know it matters a lot, sure.

I've got some home brand "100% wholegrain" oats here that say they contain 1g Sugars per 100g, less than half 1g per 40g shown in your table.

And even 1g per 40g is double 2g per 40g, not 'nutritionally identical'.

Do you have a point?

Here's Shredded Wheat: https://www.postshreddedwheat.com/products/the-original/

0g sugar per 60g serving size. Do I now conclude that you were trying to fool me into thinking oatmeal contains less sugar than cereal when in fact it contains much more?

No, that's nonsense, oatmeal is a kind of cereal. The amount of sugar in it isn't even related to whether it's oatmeal.

Oats are low GI and breakfast cereals are high GI

Oatmeal (if unsweetened/unflavored) has about the same GI as orange juice or cake made from some Betty Crocker boxed cake mixes and is just slightly lower-GI than the American formulation of Coca-Cola (see #333 Oatmeal (Canada), GI value of 54 ± 4 in the table at https://www.sciencedirect.com/science/article/pii/S000291652...).

I think oatmeal and other high-GI foods are promoted as low-GI in hopes of helping wean diabetics and pre-diabetics off of even worse foods (e.g. something really bad like powdered donuts), akin to how methadone is used to try to help heroin addicts. But genuine low-GI foods would be things like eggs, cheese, or chicken breast (all with nearly 0 GI) or some raw veggies like raw broccoli or the greens in a leafy salad (in the neighborhood, roughly, of 10-20 GI). Cooking low-GI vegetables like broccoli defeats the purpose and raises its GI to around the same value as oatmeal.

I wrote oats, not oatmeal (I don't think we really use that term in the UK). AIUI "Oatmeal" can refer to various things, including high GI porridge.

I only buy steel-cut oats, which various sources on google say are around 42 GI [0][1]. I do concede that any form of oats are on the upper-end of low and/or medium, and aren't some magic super food and one should not focus just on GI.

Steel cut oats are definitely better than most breakfast cereals however.

Joel Fuhrman in his book on reversing diabates also recommends small portions of oats (but mostly says to eat veggies).

Here are the UK figures for Cheerios multigrain and Quakers rolled oats. Cheerios have 17x the sugar. I think they used to be worse in the past before UK sugar regulations led to lots of changes to breakfast cereals.

I use 100g because they have different servings amounts. In the UK, the serving size is just 30g not 39g.

I would note that reducing such foods to tables can miss the point. They make me feel very different to eat. One is a very moreish sugary frankenfood that makes me lose control of my appetite. I can eat it by the box. The other is something that makes me feel good but if I make too much, I'm done and can't finish it. Eating an excess is physically hard.

Those don't look like plain Cheerios, but one of the many sweetened varieties.

I haven't seen a sugar-free variety in UK supermarkets. Standard Cheerios have always been sweet. I would call the "sweet" varieties things like Honeynut which have 22.4g of sugar per 100g.

Hmm, seems plain Cheerios are indeed not available in the UK; [1] shows only flavored versions...

[1] https://www.nestle-cereals.com/uk/brands/cheerios

The "low sugar Vanilla O's" sound ridiculous but contain comparable sugar to base Cheerios.† Presumably they have more vanilla flavoring.

† Which is to say, there's still a bit of added sugar, but not much, just like in the base Cheerios. (The rolled oats have no added sugar. The difference between "1g" of sugar in 40g of American rolled oats and "1.1g" in 100g of British rolled oats must be down to either different oats or rounding errors.)

I feel like the constant addition of relatively small amounts of sugar to random foods that aren't even supposed to be sweet might be a bigger issue than the inclusion of big heaps of sugar in foods that are supposed to be sweet. It's difficult to find beef jerky that is less than 10% sugar by weight. Rice Krispies are also 10% sugar by weight. There's no good reason for this.

In the US, our "regular" Cheerios aren't the Multigrain kind. They're minimally sweetened, and mostly made of oat flour. See them here: https://www.cheerios.com/products/original-cheerios

Cheerios multigrain are a sweetened version

If you ask for Cheerios in the UK, this is what you get. If you get an own-brand Cheerio knock off called "Hello Loops" or something, they will have also the same level of sugar.

Might explain some of the confusion in this thread.

Here in DK we also have the usual American brands which are all full of sugar. I haven't seen anything sugar free.

The more healthy products are marked with a green mark. None of the usual brand has it because of high sugar (or sugar like) substances contained.

It's literally a "cereal grain". It's found alongside the sugar pops, bran flakes, and cheertios on grocery aisles. YOU might not think it's an alternative, but it very much is a cereal.

> It’s literally a “cereal grain”.

Right, its within the space of breakfast cereal, not an alternative to it.

I think that was the point... it isn't an alternative to cereal because it IS a cereal

Oatmeal is not oatmeal.

There's instant oatmeal. The kind that comes in packets and you just add water. Often has sugar added, often slathered with sugar. Possibly worse than a bowl of corn flakes. Highly processes with most of the starches and cellulose (fibre) reduced to simpler forms and readily and rapidly converted to glucose in the gut. High GI. Almost like candy.

There's quick-cooking AKA minute oatmeal. Gelatinizes in 3 minutes on the stove or the microwave. Still processed so the starches are easily digestible (that was the point when it was invented). Slightly better than instant oatmeal and corn flakes but still mid-level GI and GL.

Finally, there's oat meal. Steel-cut oats are just the seeds of the oat plant lightly crushed into large pieces. Not pre-cooked. Most palatable when cooked overnight. Very high in non-digestible fibre, mostly still complex starches that take considerable time to convert into glucose in your digestive system. Low GI.

It's oat meal that is most associated with glucose and blood pressure control, not so much oatmeal. Rule of thumb: the longer it takes to prepare, the more it takes to digest and the better it is for you if you're concerned about a healthy diet.

But the point is that oatmeal is not oatmeal, and discussing it as if it is is always going to be misleading.

I'm a type 1 diabetic and get to monitor my blood sugar level, and there's just not much difference in between these oatmeal styles when it comes to digesting the carbs.

> Finally, there's oat meal. Steel-cut oats are just the seeds of the oat plant lightly crushed into large pieces.

That's still "oatmeal". "Oat meal" would be a slightly odder way to say oat flour.
