What Happens to a Meal

You sit down at the table and consume a three-course dinner. Somewhere between chewing and excreting, your body absorbs certain substances from your food, mostly across the surface of your small intestine. From the carbohydrate you eat, your body will absorb sugars, all of which are, or quickly and easily become, glucose. From fat, it absorbs glycerol and fatty acids, and from protein, it absorbs amino acids, the building blocks of all cells.

Obviously, if you eat a lot of carbohydrate, you'll end up with a lot of glucose in your blood. Sounds good, doesn't it? All that energy coursing through your system. Eat sugar, starches and fruits and you're going to get those blood-sugar levels up fast, aren't you? If you love candy bars, perhaps you're saying, "That's great-the more I eat, the more energy I'll have."

Alas, a bad mistake. You see, the human body evolved and primitive humans thrived as hunter-gatherers who subsisted primarily on meat, fish, vegetables, fruit, whole grains and seeds and nuts. Candy bars were few and far between. The human body is used to dealing with unrefined foods as they occur in Nature. Consequently, your body's capacity to deal with an excess of processed foods is pretty poor, which is why our twenty-first-century way of eating so often gets us into trouble.

If you don't understand this yet, let's look at what insulin and the other energy-controlling hormones do when you eat.

Diabetes 2

Diabetes 2

Diabetes is a disease that affects the way your body uses food. Normally, your body converts sugars, starches and other foods into a form of sugar called glucose. Your body uses glucose for fuel. The cells receive the glucose through the bloodstream. They then use insulin a hormone made by the pancreas to absorb the glucose, convert it into energy, and either use it or store it for later use.
