Hi,
I haven"t posted yet. My name is Rona Moore and I have the book in front of me.
Chapter 4 is about Digestion and Metabolism. The authors feel that the digestion and metabolism of foods are the keys in maintaining good nutrition and normal body weight. They go into specifics of the digestive process with suggestions for improving both.
1. Chew your food into smaller pieces because the smaller the pieces of food are the easier they are to digest. This also helps to prevent indigestion.
2. Don't eat a fatty meal later in the evening or at night because it can lead to acid reflux and extreme discomfort. This also can occur after heavy drinking and then eating.
3. Because fiber is the last thing that the stomach digests, carbohydrates with fiber, such as stone-ground wheat bread, whole-wheat pasta, beans, yams, etc. will take longer to digest, and thus have a much lower insulin-stimulating effect.
They briefly describe metabolism, then go into carbohydrates and how they break down.
While all carbohydrates break down into glucose, so break down much faster than others. Those that break down fast into glucose have a high glycemic index value, going down a continum to those that are much slower to break down which have a low glycemic value.
Proteins mostly break down into amino acids which can then be used to build up protein in our cells, or turned into glucose.
Fats must be digested through the actions of pacreatic enzymes. Its a complicated process. Cells use fat for a number of important functions.
They also talk about cholesterol and what it really is.
I hope this helps.
