Also, the mixture of bio-chemicals varies for each kind of food you ingest. For example, your body uses different bio-chemicals to metabolize the different classes of foods: meats, grains, vegetables, beans, fruits, and nuts. As you might have guessed, you need a whole different biochemical preparedness to handle drugs, alcohol, sugars, chemical additives, and toxins.However, your body adjusts to whatever diet you give it, and the most frequent foods in your diet come to be expected. Biochemical pathways become established the more they are used. Thus, if your body doesn't get an expected food, you actually begin to crave it.

In fact, your body becomes addicted to the foods you give it the most. Your metabolism so completely adjusts to your regular diet that any change from this diet becomes increasingly difficult. Ask anyone who has attempted a major shift in diet. For example, if you eat meat regularly, your metabolism will take a long time to adjust to a vegetarian diet. Although the same nutrients are available, your body doesn't have the biochemical preparedness. The ability is there. Your body can metabolize vegetarian meals. No problem. But to gain the same efficiency with a new diet can take from one to seven years. The important thing to remember is this: Metabolism depends on diet. For our purposes, "diet" includes not only the nutritious foods but also the non-nutritious foods, such as sugar and alcohol, as well as other substances, such as chemical additives in foods, environmental toxins, and drugs. You can change your metabolism if you change your diet. Although it will take a long time to change your metabolism significantly, you'll feel incredible improvements after just a few months. You'll discover the kinds of changes you need to make in a later articles. We become addicted to drugs partly as a way to avoid life's misery. In our minds at least, we become unwilling to suffer.

Real life is loaded with suffering. We not only experience myriad physical pains but also must cope with psychological pain. Many events make us ache inside. Things happen that cause us to feel sad, miserable, angry, nervous, tense, disgusted, confused, weakened, tortured, cheated, abused, frightened, or upset.
