"Unhealthiest" Foods
The "unhealthiest" foods tend to be those that least resemble their original natural ingredients and those that have the most added refined and artificial additives. Prime examples are the so-called "white foods"-white sugar, white flour, and white fat, and the gamut of foods in which they are the principal ingredients. It's not that these foods are white in color-many of them are actually not. It's that these foods have had many of their natural components-including their natural colors-processed away. "White foods" is simply the shorthand label that we are using when we refer to these heavily processed, nutrient-depleted foods. - "White sugar" includes refined sugar cane or sugar beets having virtually all B vitamins, minerals, antioxidants, and other essential nutrients removed. Corn syrup is also a "white sugar," made from processed cornstarch and essentially devoid of other nutrients.
- "White flour," analogously, is whole wheat flour minus its nutrient-packed wheat germ and fibrous bran. Nutritionally speaking, white flour is a ghost-like shadow of its original whole grain.
- "White fat" can include rendered animal lard, vegetable oils "hydrogenated" to make them hard at room temperature, and refined fats such as cottonseed oil. Hydrogenation is a chemical process that transforms natural fats into more saturated trans-fatty acids that do not occur naturally and which are strongly associated with cardiovascular disease.
Foods having "whites" as their primary ingredients are frighteningly ubiquitous! Examples include soft drinks, breads, hamburger and hotdog buns, crackers, pasta, pastries and pastry fillings, pies, cakes, frostings, margarine and bread spreads, jellies, sweets and candies, frozen dinners, pizzas, snack foods, doughnuts, candy bars, and cookies-all of which are common snack and convenience foods. Indeed, many of these combine all three whites together-white sugar, flour, and fat! Furthermore, these foods frequently contain artificial colors, artificial flavors, preservatives, texturizing and processing agents, and other additives that further detract from their nutritional stature and your health. These are among the foods that I would consider to be the unhealthiest and the ones that I would avoid.
Thanks again George!

All About Fiber....
Dietary fiber comes from the thick cell wall of plants. It is an indigestible complex carbohydrate. Fiber is divided into two general categories- water soluble and water insoluble.Where is it found?
Whole grains are particularly high in insoluble fiber. Oats, barley, beans, fruit (but not fruit juice), psyllium, and some vegetables contain significant amounts of both forms of fiber and are the best sources of soluble fiber. The best source of lignan, by far, is flaxseed (not flaxseed oil, regardless of packaging claims to the contrary).
Who is likely to be deficient?
Most people who consume a typical Western diet are fiber-deficient. Eating white flour, white rice, and fruit juice (as opposed to whole fruit) all contribute to this problem. Many so-called whole wheat products contain mostly white flour. Read labels and avoid “flour” and “unbleached flour,” both of which are simply white flour. Junk food is also fiber depleted.
The benefits of eating whole grains are largely derived from the beneficial constituents present in the outer layers of the grains, which are stripped away in making white flour and white rice. Preliminary research has found that women who ate mostly whole grain fiber had a lower mortality rate than women who ate a comparable amount of refined grains.1
