antioxidantförsvaret

Antioxidantförsvaret is a Swedish term referring to the body's defense system against oxidative stress. Oxidative stress occurs when there is an imbalance between free radicals and antioxidants in the body. Free radicals are unstable molecules that can damage cells, DNA, and proteins, contributing to aging and various diseases.

The antioxidant defense system comprises a complex network of enzymes and molecules that neutralize free radicals. These antioxidants can be produced by the body itself, such as glutathione and superoxide dismutase, or obtained from the diet, including vitamins C and E, carotenoids, and various plant-derived compounds. These dietary antioxidants scavenge free radicals, preventing them from causing harm.

When the antioxidant defense is overwhelmed, or when the production of free radicals is excessively high, oxidative stress can lead to cellular damage. This damage has been implicated in the development of chronic conditions like cardiovascular disease, cancer, neurodegenerative disorders, and inflammatory conditions. Maintaining a robust antioxidant defense is therefore crucial for overall health and disease prevention. Factors such as diet, lifestyle choices, and exposure to environmental toxins can influence the effectiveness of this defense system.
