Antioxidants—also known as “free radical fighters”—have been making waves in the health and wellness industry. But what exactly do they do? Are they genuinely beneficial, or are they just another marketing buzzword? More importantly, is it better to get them from food or supplements? Let’s break it down.

Why Do We Need Antioxidants?

Free radicals are natural by-products produced by the body when processing food, particularly refined and processed foods, trans fats, artificial sweeteners, and certain additives. They are also generated due to environmental factors like pollution, smoking, exposure to pesticides, and even medical treatments such as chemotherapy.

If free radicals build up faster than the body can remove them, they cause oxidative stress, which can lead to cell damage, inflammation, and long-term health issues. This is where antioxidants come in—they help neutralise free radicals and protect cells from damage.

Best Natural Sources of Antioxidants

Different antioxidants serve different functions, so eating a varied diet is key. The best sources come from plant-based foods, particularly brightly coloured fruits and vegetables.

To naturally boost your antioxidant intake, try these simple dietary changes:

• Eat a variety of fruit and veg – Include a portion in every meal and snack.
• Sip on green or matcha tea – Packed with polyphenols that support cell health.
• Spice it up – Turmeric, cumin, oregano, ginger, cloves, and cinnamon enhance flavour and antioxidant content.
• Snack wisely – Opt for unsalted nuts and seeds, especially Brazil nuts, sunflower seeds, and almonds.
• Don’t forget protein sources – Eggs, dairy, liver, and mushrooms contain key antioxidants such as selenium and vitamin A.

Should You Take Antioxidant Supplements?

While supplements may seem like a quick fix, they aren’t always necessary—and in some cases, they can do more harm than good.

The National Institutes of Health (NIH) advises caution with high doses, as they can be harmful or interfere with medications. If you’re considering supplements, it’s essential to consult a healthcare professional first.

There are some potential benefits for people at risk of age-related macular degeneration, but again, this should be discussed with a doctor. The best way to get antioxidants is through food. If your diet is lacking in fruit and veg, try starting with two servings of fruit and three servings of vegetables daily before considering supplements.

Antioxidants play a crucial role in cell protection and overall health, but balance is key. Instead of relying on supplements, aim to eat a colourful, whole-food diet that provides a wide range of natural antioxidants.
