Harmful oxidative stress, dangerous free radicals and antioxidant protection are important concepts for a healthy lifestyle. Here is a brief explanation of the terms.

Free radicals

Free radicals are unstable, highly reactive molecules, such as reactive oxygen compounds that poison hydrogen peroxide, which has the capacity to oxidize their surroundings. The body has enzymes that neutralize free radicals, while the immune system uses free radicals to kill and destroy adventitious pathogenic cells, such as bacteria.

Oxidation

Oxidation is a chemical reaction with a counterparty that is called reduction. When electrons pass from molecule A to molecule B says that B is oxidized while A is reduced. Oxidation damage lipids, proteins and DNA, leading to a degeneration of the cell all the parts often likened as metal corrosion.

Balance

Healthy balance between oxidation and reduction in the body’s cells. This is when the balance shifts towards oxidation more than the body can neutralize and repairing talking about oxidative stress. Oxidative stress is a critical piece of the difference between normal aging and the development of diseases.

Vegetables, then fruit and vegetables, is perhaps the most common source of antioxidants. A good choice in this category is the cocoa, which contains very high amounts of substances related to immunity and nervous system.

Antioxidants

Antioxidants, was really more properly be called reductants and molecules are oxidized more easily than their surroundings. This gives them the ability to neutralize free radicals and protect against oxidative stress. It is valuable to take in antioxidants from diet or through supplements.

Importance of Training

It is well known that physical exercise protects neurons against degeneration. A study from February 2015 states that it is the training effect, that is, the balance between oxidation and reduction which allows physical exercise protects against Alzheimer’s disease.
