Antioxidants neutralise harmful free radicals in the body, reducing the risk of chronic diseases.

Found in various fruits, vegetables, and other whole foods, offering both protective and anti-inflammatory benefits.

What Are Antioxidants?

Antioxidants are molecules that fight free radicals—unstable atoms that can cause damage to cells and contribute to ageing and diseases like cancer, heart disease, and diabetes. These compounds can be naturally found in many foods, primarily fruits and vegetables.

Free radicals are byproducts of normal cellular processes or external factors like pollution, UV exposure, and smoking. By neutralising these molecules, antioxidants prevent oxidative stress and its harmful effects on the body.

Health Benefits of Antioxidants

Protects Against Chronic Diseases
- Antioxidants reduce the risk of conditions like heart disease, cancer, and diabetes by minimising oxidative damage.

Supports Skin Health
- They combat damage from UV rays and pollution, promoting healthier, more youthful-looking skin.

Boosts Immunity
- Antioxidants, such as vitamin C, enhance immune function by protecting cells from damage.

Improves Brain Health
- Evidence suggests that antioxidants like flavonoids may reduce the risk of neurodegenerative diseases such as Alzheimer’s and Parkinson’s.

Reduces Inflammation
- Antioxidants help lower inflammation, which is linked to chronic conditions like arthritis and metabolic syndrome.

Foods High in Antioxidants

Incorporating these antioxidant-rich foods into your diet can naturally support your health and protect your body from oxidative stress.

For practical tips on incorporating antioxidant-rich foods into your diet, refer to the UK NHS Eat Well Guide.

Antioxidant Supplements: A Balanced Perspective

While antioxidant supplements are available, prioritising whole foods is recommended. Whole foods provide antioxidants along with essential vitamins, minerals, and fibre that supplements lack.

Supplements may be helpful in cases where dietary intake is insufficient, but over-supplementation can sometimes do more harm than good. Always consult a healthcare professional before introducing supplements into your routine.

Adding More Antioxidants to Your Diet

Incorporating more antioxidant-rich foods into your meals can be simple and rewarding. Consider adding vibrant fruits and vegetables, like berries and leafy greens, or sipping on antioxidant-rich green tea.

Conclusion

Antioxidants are essential for maintaining health and protecting the body from oxidative damage. By prioritising a diet rich in colourful fruits, vegetables, and whole foods, you can naturally support your immune system, reduce the risk of chronic diseases, and promote overall well-being.

Remember, the best sources of antioxidants come from whole foods—not just for the antioxidants themselves, but also for the array of additional nutrients they provide.
