When free radicals run amok, they can inflict damage on various cellular components, including proteins, lipids, and even your precious DNA. This oxidative stress can manifest in a myriad of ways, ranging from subtle cellular dysfunction to more severe consequences.
Protein Damage: Free radicals can alter the structure and function of proteins, disrupting their ability to carry out essential tasks within your cells.
Lipid Peroxidation: These unstable molecules can target the lipids (fats) in your cell membranes, compromising their integrity and potentially leading to cell death.
DNA Damage: If left unchecked, free radicals can wreak havoc on your genetic material, potentially contributing to mutations and the development of various diseases.
It is a delicate dance, where too many free radicals can throw your cellular systems into disarray, potentially paving the way for a host of health issues, including chronic inflammation, cardiovascular disease, neurodegenerative disorders, and even cancer.
Free Radicals and Ageing: Myth vs Reality
One of the most widely discussed topics surrounding free radicals is their alleged role in the ageing process. You've likely heard the whispers – free radicals are the culprits behind those pesky wrinkles and the gradual decline in our vitality. But is this merely a myth or a scientific reality?
The truth lies somewhere in the middle. While free radicals do contribute to the ageing process by inflicting oxidative damage on cells over time, they are not the sole perpetrators. Ageing is a complex phenomenon influenced by a myriad of factors, including genetics, lifestyle choices, and environmental exposures.
It is important to note that a certain level of free radical activity is natural and even necessary for various biological processes. The key lies in maintaining a delicate balance, where their numbers are kept in check by our body's antioxidant defenses.
Antioxidants: The Defence Against Free Radicals
Enter the superheroes of the cellular world – antioxidants! These mighty molecules are nature's gift to combat the potential havoc wreaked by free radicals. Think of them as the valiant knights in shining armor, ready to neutralize the unstable radicals and restore balance to your body.
Antioxidants come in various forms, both naturally occurring and synthetic, and they work tirelessly to neutralize free radicals by donating electrons or breaking their chain reactions. Some of the most well-known antioxidants include vitamins C and E, carotenoids, flavonoids, and compounds like glutathione and melatonin.
But wait, there's more! Your body is equipped with its own arsenal of antioxidant enzymes, such as superoxide dismutase, catalase, and glutathione peroxidase, which work in tandem with dietary antioxidants to maintain a healthy equilibrium.
Dietary and Lifestyle Changes
