Iv been having this in the morning and wondered if it is my healthy option B?

It doesn't show as hex b on the app unfortunately.
Is it similar to Ready Brek, like flakey rather than like the oats so simple porridge oats?

No I would say it's more flakey rather than porridge oats! Does that matter?

You're probably better getting something that's more like the proper porridge oats, the flakey type ones most likely don't have enough fibre in them to count as a B choice. the Lidl plain porridge oats are a hex b choice though (see pic)
For the ones you asked about its 4.5 Syns per 25g

Thank you, I'm gonna get the Quaker porridge oats. Hopefully this hasn't affected my weight loss!!
