You can also use almonds as an ingredient of a breakfast smoothie. Soak
almonds overnight and make a smoothie by adding some berries or fruits and
some water and blending this all with a blender. This is probably one of the
healthiest ways to use almonds. Delicious too. Soaking helps in the
digestion and absorption of nutrients.

Double roasting is strange. :(

Yes!

The only thing that you are getting out of double roasted almonds is
protein and some fiber.

My favorite almond preparation is raw almond butter.
Try it if you can find it. I think they roast almonds to
kill bacteria and give the nuts a longer shelf life.
My wife blends raw almonds in our smoothies. No need
to use almond butter there.

First, I would recommend to keep the intake of foods high in
polyunsaturated fatty acids (PUFAs) low - mainly nuts and seeds and any
products made from them (mostly oils) and containing them. PUFAs are
unstable, they oxidize readily resulting in harmful free radicals. High
PUFA intake have been repeatedly linked with cancer, heart and
inflammatory diseases.

If you do eat nuts make sure to soak them before consumption - to lower
or eliminate natural anti nutrients like enzyme inhibitors. Soaking
makes them much easier to digest also. Do not eat more then a few
handfuls a week.

I haven't seen data on this, but from the taste I'm certain that nuts
deteriorate much faster after roasting than before. I buy raw, dry
roast myself, then keep in the frig.
