Some high-fiber observations to add to David's -
BREAD: If the label doesn't say "100% Whole Wheat" or "100% Whole Grain" it is NOT high fiber! Many commercial bakeries label breads as "wheat bread" and use about three tablespoons of whole wheat to the loaf, adding dye (!) to make it caramel colored so people will think it's the real thing. Ugh.
BREAKFAST CEREAL, COLD: The high fiber ones I've found are: Wheaties, Cheerios, shredded wheat, Shredded Wheat Squares (NOT the frosted ones, yecch), All Bran, GrapeNuts, Raisin Bran, puffed wheat. The raisin bran, All Bran, and Wheaties are plenty sweet enough for me without sugar; to the others I add a very small amount of sugar. Careful! They are very easy to oversweeten, especially the GrapeNuts. The shredded wheat squares also make wonderful dippers in place of all those greasy salty chips, and are great with soup in place of saltines.
BREAKFAST CEREAL, HOT: Oats, cracked wheat, brown rice, instant Ralston. I'm sure there are others that I haven't discovered yet . . .
PANCAKES & WAFFLES: Use whole wheat flour in place of white. You may need to add a bit more liquid to the batter.
BREADS, MUFFINS, BISCUITS, QUICK BREADS: See above. I also use whole wheat flour in my cake recipes, using 1 cup minus 2 tbsp for every cup of white flour called for.
BEANS: I've found that if I put my beans on to cook at night, covering them with three inches (or more) of water, set the heat very low and then let them cook all night long, they come out tasting wonderful AND don't seem to create the usual social problems. Great Northern beans are especially flavorful with this extra-long cooking. BTW, wait to add any salt until serving time; the beans come out much better. Don't know why, just know that!
SALADS: Make your own dressings and you will be amazed at the improvement in taste! Also amazing to me was the improvement when I switched to olive oil. I've also found it's possible to replace half of the oil with water, if I shake the bottle like a maniac. BTW, don't waste your hard-earned money on cheap olive oil. Yuck! Carapelli is about the best brand available in my neck of the woods. I like their green bottle, too; it keeps the oil in the dark where it belongs.
cookies140, you are going to LOVE this way of eating! Once your body starts getting real food, it will never again be happy with anything less. Sort of like going to the dance wearing burlap instead of your usual velvet and diamonds!
