We all know that a nutritious diet is one of the smartest ways to take care of ourselves. But none of the communities featured in the series engage in dieting – so no sad plates devoid of flavour and fun here. Rather, they focus on three basic principles of eating and drinking.

Plant-based eating

Most inhabitants of blue zones eat a mainly plant-based diet, with 95% of their food intake comprising fruits, vegetables, pulses and nuts. Interestingly, cruciferous vegetables such as broccoli and cauliflower have been shown to ward off cancer, improve heart health and even alter thyroid function – all contributing to longevity.

Drink wine

In good news for all non-sober folks, the documentary reveals that enjoying a glass of wine with your (plant-based) dinner can help you to live longer – just make sure it’s red wine and don’t overdo it. Red wine has been shown to triple the body’s ability to absorb antioxidants and it can contribute to better gut health.
