MDF for built-in cabinets?

I am having my basement remodeled. When the contractors were firring out the basement walls, on impulse, I had them make me some space for some built-ins on either side of a window. these are about 30" w x 32" t x 7 1/2" deep. When doing trim work, they cut me the mitered trim to frame this in. I am planning on creating a simple carcase that will have sides, top and bottom, and two fixed shelves. I plan to rabbet the top and bottom, as well as the back, and dado out for the shelves.

I would like to use 3/4" MDF for this, but I am wondering if I can support weight in a 3/4" shelf that is 30" wide, in a dado when using MDF? Should I go with plywood instead?

Thanks!

You'll just want to add a 1x2 face to the shelves that is glued and fastened.

I am sorry. Could you explain what that means?

Picture an L turned clockwise 90 degrees. That is what each shelf should look like from the side. The 1x2 will be glued horizontally to the face of each shelf so it will look 1 1/2" wide when looking at it from the front. The 1x2 will stiffen the shelf and prevent it from drooping in front.
