Eat the Rainbow: Why Colourful Food Is Your Best Health Insurance

No matter how healthily you eat, one thing is certain, you need plenty of antioxidants in your diet. And the best way to get them? Fill your plate with colourful, plant-based foods.

Antioxidants help quench free radicals, unstable molecules that damage your cells, proteins, and DNA. This process, known as oxidative stress, contributes to aging and disease. By reducing oxidative stress with a variety of antioxidant-rich foods, you support your immune system, lower inflammation, and boost long-term health.

Are You Eating Enough Plants?

Surprisingly, only 15% of people manage to eat five portions of fruits and vegetables daily, even though these foods are rich in vital antioxidants. To strengthen your body’s natural defences, it’s essential to eat a wide variety of colours every single day.

Each colour provides unique phytonutrients that work in synergy to protect your health:
