Free Radicals (Oxidative Stress): Risk Factors

The following risk factors are important in oxidative stress: biographic and immutable risk factors.

  • Genetic stress from parents, grandparents (genetic individuality, which means genetically determined different equipment, e.g., with radical-scavenging enzymes).
  • Age

Modifiable risk factors modifiable by behavior.

  • Diet low in vital nutrients (few cereal products, less than 5 servings of vegetables and fruits (400-800 g/day), few milk and dairy products, less than one to two fish per week, etc).
  • Malnutrition and malnutrition including over- and undernutrition.
  • Smoking the substances inhaled in a single puff from a cigarette, form 1015 free radicals in the lungs a hundred times more than we ourselves have body cells. When detoxifying the tar inhaled at the same time, an additional 1014 free radicals are formed.
  • UV rays for example sunlight, solarium
  • Extreme physical labor
  • Competitive and high-performance sports

Treatable risk factors Diseases known to be associated with oxidative stress.

Laboratory diagnoses laboratory parameters that are considered independent risk factors.

  • Malonaldehyde (MDA), 4-hydroxy-2-nonenal (HNE), and 2-propenal (acrolein) indirect indicators of oxidative stress (as end products of lipid peroxidation).

Drugs

X-rays

  • Irradiation for tumor diseases
  • Ionizing rays

Chemotherapies

Surgeries

Environmental pollution and intoxications

  • Occupational contact with carcinogens
  • Liver damage from, for example, hydrogen tetrachloride poisoning, ethanol, etc.
