Why We Get Sick?

What causes illness? The organs and tissues in our bodies are made of cells. It is said these cells need more than 200 nutrients to stay healthy. Beside the obvious supplying nutrients, what else cause illnesses? It has been found that stress causes people to get sick. And there are all kinds of stress, the major ones being:
1. Emotional
2. Environmental
3. Oxidative

Emotional stress can come from so many sources:
1. Financial
2. Marital
3. Familial
4. Death
5. Breakups - girl/boy friends, best friends, parental
6. Illness of loved ones
7. Even getting married causes stress.

Environmental stress:
1. Inhaling second hand cigarette smoke
2. Inhaling vapor from gasoline
3. Exhaust from vehicles
4. Consuming food contaminated with insecticide, chemicals, etc
5. Living in neighborhood near an industrial park that spew toxic waste

Oxidative Stress:
Molecule with an unpaired electron is highly reactive. Free radicals, typically unstable oxygen molecules, roam our bodies "grabbing" an electron from a stable molecule causing oxidation or "cellular rust". A component of cells such as DNA can be damaged by free radicals. If not repaired, damaged DNA can cause mutations resulting in heart diseases, memory loss and cancer. Oxidative stress is one of the causes of aging.
