Abnormal food-body interactions cause sensations which should alert us to problems in the food and problems in the way our bodies respond to different food combinations.

Some of the sensations are mild discomforts broadcast from the digestive tract surface to signal displeasure with your food choices. Indigestion, heartburn, and nausea are discomforts which originate from the stomach, soon after food is eaten.

Other events occur hours after eating as food digestion and absorption is taking place. Some of the abnormal events have to do with the self-regulating activity of the digestive tract or to the nature of the food, its chemistry, its toxicity, and its effect on your metabolism. Food borne infections may not become apparent for many hours to days after eating contaminated food.

Normal is not normal:  The foods implicated in causing illnesses are common foods that almost everyone eats. To become a healthy person you have to redefine normal food.
