Are you an advocate of "food combining"?
I am aware that many practitioners use food combining as part of their dietary recommendations. I do not, simply because the blood type diets do specifically what food combining attempts to do non-specifically.
Proponents of food combining claim that correct food combinations are important for proper digestion, utilization, and assimilation of the nutrients our body needs to sustain life. Different foods require different digestive enzymes to aid in the digestive process - some acid, some alkaline. When acid and alkaline foods come in contact, they neutralize each other and retard digestion. If the food we eat is not properly digested, it will pass through the intestinal tract without being completely broken down, getting stuck between the crevices located in the intestinal track - thereby causing the toxic wastes to ferment and putrefy.
Critics claim that there's no evidence to support such contentions. Nearly all foods are themselves combinations. If you eat beans, for example, you're getting carbohydrates (sugars and starches), protein and fiber, among other things. Bread combines protein, carbohydrates, a little fat and many other things. A simple dish like macaroni and cheese, a peanut butter sandwich, or oatmeal with milk contains sugars, starches, protein and fat. Our digestive system handles food combinations very efficiently. The process begins in the mouth as we chew food and saliva acts upon it, beginning the breakdown of starches into sugars. Other enzymes come into play along the line, resulting in almost complete digestion and absorption of nutrients, no matter how they are combined.
