Healthy eating

So, lately I have been thinking about eating healthier. Not to loose weight, but to gain energy and feel all around better. I have noticed that too much comfort foods, while they feel oh so good, can cause me to be sluggish, lazy, have a foggy mind and indigestion.
The problem is, I LOVE pastas and breads and 'creamy' things. In my healthy-eating plan, I will try to eat only whole-wheat pasta. The thing is, I am very picky when it comes to texture. I don't like the texture of whole-wheat, beans, or nuts. I made a white bean alfredo sauce the other day, and it tasted alright, but the texture is what turns me off. How can I get past the gritty texture of healthy foods???
