Antioxidants for women: aging protection

Antioxidants for women: aging protection

I. Fundamentals of antioxidants and aging

A. Free radicals and oxidative stress: the main culprits of aging

1. What are free radicals? Free radicals are unstable molecules containing an immutable electron. This instability forces them to “steal” electrons in other molecules in order to stabilize. As a result, a chain reaction that damages the cell is launched.

2. How are free radicals formed? Free radicals are formed naturally in the process of metabolism, when the body processes food into energy. However, their formation is also enhanced by external factors:

   • Ultraviolet (UV) radiation: Sunlight is a powerful source of free radicals. UV radiation damages DNA and cell membranes, stimulating their formation.
   • Environmental pollution: Sow, exhaust gases of cars, industrial emissions contain high concentrations of free radicals.
   • Smoking: Tobacco smoke contains thousands of chemicals, many of which are powerful free radicals.
   • Alcohol: Excessive alcohol consumption can lead to damage to the liver and an increase in the formation of free radicals.
   • Revised foods: Products containing trans fats, sugar and other artificial ingredients can contribute to oxidative stress.
   • Chronic stress: Long -term stress stimulates the production of cortisol, stress hormone, which can increase the formation of free radicals.
   • Some drugs: Some drugs, such as antibiotics and anti -inflammatory drugs, may have side effects associated with oxidative stress.
   • Intensive physical exercises: Although physical exercises are good for health, excessive physical activity can temporarily increase the formation of free radicals.

3. What is oxidative stress? Oxidative stress occurs when an imbalance between the formation of free radicals and the ability of the body to neutralize them is observed in the body. As a result, free radicals damage cells, tissues and organs.

4. Cell damage mechanisms with free radicals:

   • DNA damage: Free radicals can damage DNA, causing mutations that can lead to cancer and other diseases.
   • Lipid damage: Free radicals can oxidize lipids (fats), which are important components of cell membranes. This leads to a violation of cell functioning and inflammation.
   • Protein damage: Free radicals can oxidize proteins, changing their structure and function. This can lead to a violation of cellular processes and the accumulation of damaged proteins.

B. The influence of oxidative stress on women aging

1. Skin aging: Oxidizing stress is the main cause of skin aging. It contributes to:

   • The appearance of wrinkles: Damage to collagen and elastin with free radicals leads to the loss of elasticity and elasticity of the skin, which leads to the formation of wrinkles.
   • Pigmentation: Free radicals stimulate the production of melanin, which leads to the appearance of age spots and an uneven skin tone.
   • Dry skin: Oxidative stress disrupts the barrier function of the skin, which leads to loss of moisture and dryness.
   • Inflammation: Free radicals cause inflammation, which can aggravate skin diseases, such as eczema and rosacea.

2. Hormonal changes: Oxidative stress can affect hormonal balance in women, especially during menopause. He can aggravate the symptoms of menopause, such as tides, night sweating and mood swings.

3. Cardiovascular diseases: Oxidative stress contributes to the development of atherosclerosis, the main cause of cardiovascular diseases. It oxidizes LDL cholesterol (poor cholesterol), which leads to the formation of plaques in the arteries.

4. Neurodegenerative diseases: Oxidative stress plays a role in the development of neurodegenerative diseases, such as Alzheimer’s disease and Parkinson’s disease. It damages neurons (nerve cells), which leads to cognitive impairment.

5. Weakening of the immune system: Oxidizing stress can weaken the immune system, making women more susceptible to infections.

6. Reduced fertility: Oxidative stress can negatively affect the fertility in women, damaging the eggs and violating the function of reproductive organs.

C. The role of antioxidants in the fight against aging

1. What are antioxidants? Antioxidants are molecules that can neutralize free radicals, giving them electrons, without becoming free radicals themselves.

2. How do antioxidants protect cells? Antioxidants act as “cleaners” of free radicals, preventing their damaging effect on cells.

3. The main types of antioxidants:

   • Vitamins: Vitamin C, vitamin E, vitamin A.
   • Minerals: Selenium, zinc, manganese.
