If only!
My other half refuses to bake me any crumbles these days in order to try and restrict my waist expansion.

Sadly, I have to make do with yoghurt as an accompaniment.
Everything in moderation
I'm sure you'd find good reason to convince your good lady and enjoy a good crumble
Oats. Lowers cholesterol
Rhubarb. Keeps you regular.
Sugar. To prevent blood sugar dropping too low
Milk. For the custard Calcium for the bones. Very important as we age
Plus all the minerals to aid cognitive thinking, muscle health etc etc etc
Mixing by hand and not electric consumes calories and saves the ozone layer
What else have I missed?
Life without rhubarb crumble doesn't bear thinking about
