Wtf?

I'm reading this book out of curiosity since I found it on a torrent site...Rather not say which one because I think it will effect the responses I get. The book basically promotes fruit and that fruit didn't make America fat.. Fast food and fat did.
I'm curious to people's opinions on this... Since it seems to be the opposite of what I've always read and have experienced.
Meeting Fruit Concerns
The mechanism that causes blood sugar to rise out of control is actually very easy to understand. Let's begin with a highly simplified description of how our bodies process sugar.
Sugar's Journey Through the Body
To be used as fuel for our cells, the sugars we eat travel a three-stage journey through our
• Stage Sugars start out in the digestive tract when we eat them.
• Stage They pass through the intestinal wall, into the bloodstream.
• Stage 3: They then move smoothly and easily out of the bloodstream and into our cells. This occurs rapidly, often in minutes.
When we eat a high-fat diet, the sugar gets trapped in stage 2, and the body works overtime, sometimes to the point of exhaustion and disease, in an effort to move the sugar out of the Meanwhile, the sugar backs up in the blood, creating sustained, elevated blood sugar that wreaks havoc on the body in the form of Candida, fatigue, diabetes, etc.
What happens in the presence of fat that causes sugar to pile up in our bloodstream? It has to do with the pancreas. Under the direction of the brain, the pancreas is responsible for producing a hormone known as insulin. One of insulin's roles is to attach itself to sugar molecules in the blood and then find an insulin receptor in the blood-vessel wall. The insulin can then transport the sugar molecule through the blood-vessel membrane to the interstitial fluid (the fluid between the cells) and continue to escort sugar across another cell into the cell itself.
In the body, fat provides many needed insulating functions, including conserving body heat, absorbing shock, preventing too much water from escaping through the skin, and protecting nerve fibers. But excess dietary fat in the bloodstream creates some negative insulating effects. When we eat too much fatty food, a thin coating of fat lines the blood-vessel walls, the cells' insulin-receptor sites, the sugar molecules, as well as the insulin itself. These fats can take a full day or more to "clear" from the blood, all the while inhibiting normal metabolic activity, and preventing these various structures from communicating with each other.
Thus, too much fat in the blood impedes the movement of sugar out of the bloodstream. This results in an overall rise in blood sugar, as sugars continue to travel from the digestive tract (stage into the blood (stage 2) but cannot escape from the blood so they can be delivered to the cells (stage 3), which await their fuel.
High-Fat, Diets Raise Insulin
The entire theoretical framework of diets, like Atkins and The Zone, hang upon the notion that insulin is the root of all evil. In the view of their promoters, one needs to limit carbohydrate intake in order to limit insulin release. What they overlook is that protein- and fat-rich foods may induce substantial insulin secretion as well. For example:
• A quarter pound of beef raises insulin levels in diabetics as much as a quarter pound of straight sugar.
• Cheese and beef elevate insulin levels higher than "dreaded" high-carbohydrate foods like pasta. Journal of Clinical Nutrition 50 (1997): 1264)
• A single burger's worth of beef, or three slices of boost insulin levels more than almost two cups of cooked pasta. Journal of Clinical Nutrition 50 (1997):1264)
In fact, the Journal of Clinical Nutrition article referred to above reports that meat, compared to the amount of blood sugar it releases, seems to cause the most insulin secretion of any food tested.
A study done at Tufts University, for example, presented at the 2003 American Heart Association convention, compared four popular diets for a year. Out of the four (Weight Watchers, The Zone Diet, the Atkins Diet, and the Ornish Diet), Ornish's vegetarian diet (almost all carbohydrates) was the only one to significantly lower insulin (27%), even though that's supposedly what The Zone and Atkins (very little carbohydrates) diets were designed to
Eating a high-fat diet, cooked or raw, contributes not peripherally, but directly and causally to all of the misleadingly named "blood-sugar metabolic disorders." Given this new perspective, one might more accurately classify these diseases as "lipid metabolic disorders."
I have stated repeatedly, consuming fruit does not cause blood-sugar problems, but overeating fat does. If you remove the fat from the diet, in most cases blood-sugar levels to normal, as does pancreatic functioning. Restricting fruit from the diet is not the cure. In fact, the opposite is true.
Sugars require little time in the stomach. Immediately upon putting a simple sweet fruit into your mouth, some of the sugars are absorbed into the bloodstream from under the tongue. Fruit eaten alone or in simple, well-chosen combination on an empty stomach requires only a few minutes in the stomach before passing to the small intestines, where the sugars can be quickly absorbed. Most of the sugar from fruit travels from the intestines, to the bloodstream, and then to the cells where they are needed within minutes of its consumption.
Fats, however, require a much longer period of time, often twelve to twenty-four hours or more, before they reach their destination, the cells.
In the stomach, fats are subjected to a digestive process that usually takes several hours. When they finally do proceed to the small intestine, they are absorbed into the lymphatic system, where they often spend twelve hours or more before passing to the bloodstream. Most important, fats linger in the bloodstream for many hours longer than do sugars.
On a high-fat diet, therefore, the bloodstream always contains an excessive quantity of fat, and more is coming in at almost every meal. Essentially, even when you eat a fruit meal alone and wait hours before eating fat, those sugars are likely to mix in yourbloodstream with the fats you ate the day before causing digestive difficulties and blood sugar disorders.
