Antioxidants to protect the male body from free radicals: a detailed guide

Section 1: Understanding the threat: free radicals and oxidative stress

  1. What are free radicals?

    Free radicals are unstable molecules characterized by the presence of an immutable electron. This makes them extremely reactive, striving to capture the electron in other molecules in order to gain stability. This process triggers a chain reaction, damaging cell structures and DNA. There is nothing unusual in the formation of free radicals – this is a normal by -product of metabolism. However, when there are too many of them, the problem arises.

    • Examples of free radicals: Super -oxide anion (O2 • -), hydroxyl radical (• OH), peroxial radical (ROO •), nitrogen nitroxide (No. •).

  2. Where do free radicals come from?

    Free radicals are formed as a result of various factors, both internal and external:

    • Metabolism: Normal processes of cellular respiration (energy production) inevitably generate free radicals.
    • Inflammation: The inflammatory processes occurring in the body in response to infection or injury lead to increased production of free radicals.
    • Exercise: Intensive physical activity temporarily increase the formation of free radicals.
    • Environmental pollution: Contaminated air, exhaust gases of cars, industrial emissions contain substances that contribute to the formation of free radicals.
    • Smoking: Tobacco smoke is a powerful source of free radicals.
    • Alcohol: Excessive drinking of alcohol stimulates the production of free radicals in the liver and other organs.
    • Radiation: The effect of ionizing radiation (for example, x -rays, ultraviolet radiation) can damage DNA and lead to the formation of free radicals.
    • Some drugs: Some drugs may have a side effect in the form of increased production of free radicals.
    • Revised products: Highly processed products containing trans fats and additives can help increase free radicals.
    • Pesticides and herbicides: The impact of pesticides and herbicides used in agriculture is associated with an increase in oxidative stress.

  3. Oxidizing stress: when the balance is broken

    Oxidative stress occurs when the balance between the formation of free radicals and the ability of antioxidant systems to neutralize them is disturbed in the body. In this case, free radicals begin to damage cells, proteins, lipids and DNA.

    • The consequences of oxidative stress:
      • DNA damage: It can lead to mutations and increase the risk of cancer.
      • Lipid damage: It leads to peroxide oxidation of lipids, damaging cell membranes and lipoproteins (for example, LDL – “bad” cholesterol), contributing to the development of atherosclerosis.
      • Protein damage: Violates the structure and function of proteins, affecting enzyme activity, cell structure and immune answers.
      • Inflammation: Oxidative stress and inflammation are interconnected. Free radicals can activate the inflammatory pathways, aggravating chronic diseases.

  4. Oxidizing stress and male health: special risks

    Men are especially vulnerable to the negative consequences of oxidative stress for a number of reasons:

    • A higher metabolism level: Men, as a rule, have a higher muscle mass and, therefore, a higher level of metabolism, which leads to greater formation of free radicals.
    • Life: Men more often than women smoke, drink alcohol and expose harmful substances at work, which increases their exposure to oxidative stress.
    • Testosterone: Although testosterone is important for the health of men, its metabolism can also contribute to the formation of free radicals.
    • Reproductive health: Oxidative stress plays an important role in male infertility. Free radicals can damage sperm, reduce their mobility and the ability to fertilize.
    • Cardiovascular diseases: Oxidative stress contributes to the development of atherosclerosis and other cardiovascular diseases that are more common in men.
    • Prostate cancer: Studies show the relationship between oxidative stress and an increased risk of prostate cancer.

Section 2: Antioxidants: Natural Defenders of the body

  1. What are antioxidants?

    Antioxidants are molecules that can neutralize free radicals, preventing their damaging effect on cells. They do this, giving the electron to a free radical, without becoming unstable themselves. Antioxidants work synergically, that is, their effectiveness increases with joint action.

  2. Types of antioxidants:

    Antioxidants can be classified according to various criteria, including by origin (endogenous and exogenous) and chemical structure.

    • Endogenous antioxidants: Synthesized in the body.

      • Glutathione: One of the most powerful antioxidants produced in cells. He plays an important role in detoxification and maintaining the immune system.
      • Superoxidydadysmutaza (sod): An enzyme that turns superoxide anion into hydrogen peroxide, which is then neutralized by other enzymes.
      • Cataala: An enzyme that breaks down hydrogen peroxide into water and oxygen.
      • Glututioneperoxidase (GP): A family of enzymes using glutathione to neutralize hydrogen peroxide and other peroxides.

    • Exogenous antioxidants: Enter the body from the outside, with food or additives.

      • Vitamin C (ascorbic acid): Water -soluble vitamin, a powerful antioxidant that protects cells from damage, which is involved in the synthesis of collagen and strengthen the immune system.
      • Vitamin E (tocopherols): Fatable vitamin, protecting cell membranes from lipid peroxidation.
      • Beta-carotene: Vitamin A predecessor, a powerful antioxidant that protects cells from damage and supports vision health.
      • Selenium: The microelement necessary for the work of glutathioneperoxidase and other antioxidant enzymes.
      • Zinc: A trace element involved in the work of superoxidsmouth and other antioxidant enzymes, as well as supporting the immune system.
      • Coenzim Q10 (COQ10): The fat -soluble substance, which plays an important role in the production of energy in cells and has antioxidant properties.
      • Liquopin: Carotinoid contained in tomatoes and other red fruits and vegetables. It has powerful antioxidant properties and is associated with protection against prostate cancer.
      • Lutein and Zeaxanthin: Carotinoids contained in green leafy vegetables that protect the eyes from damage caused by free radicals.
      • Polyphenols: A large group of plant compounds with antioxidant properties. Include:
        • Flavonoids: Contained in fruits, vegetables, tea, wine and chocolate. Examples: Quercetin, catechins, anthocyanins.
        • Resveratrol: Contained in red wine, grapes and peanuts.
        • Curcumin: The main active ingredient of the turmeric.
        • Ellagic acid: Contained in berries, grenades and nuts.

  3. The mechanisms of the action of antioxidants:

    Antioxidants act in various ways to protect cells from damage caused by free radicals:

    • Electron returns: They give the electron to a free radical, stabilizing it and preventing it damaging it on other molecules.
    • Interruption of chain reactions: They interrupt chain reactions caused by free radicals, preventing their distribution and further cell damage.
    • Helating of metals: Some antioxidants bind metals such as iron and copper, which can catalyze the formation of free radicals.
    • Restoration of oxidized molecules: They can restore oxidized molecules, returning them to an active state.
    • Activation of endogenous antioxidant systems: Some antioxidants can stimulate the production of endogenous antioxidants, such as glutathione and superoxidsmouth.
    • Reducing inflammation: Many antioxidants have anti -inflammatory properties, which helps reduce the formation of free radicals associated with inflammation.
