How to live longer: Nutritionist shares two snacks which have been linked to a 'longer life and lowering the risk of developing chronic diseases'

The term "Blue Zones" was first popularised by explorer and author Dan Buettner in 2004. The regions in the Blue Zone include Okinawa in Japan, Ikaria in Greece, Loma Linda in the United States, Sardinia in Italy, and Nicoya in Costa Rica.

Each of these areas earned a spot in the zone as they were identified as having populations that consistently achieve higher life expectancy than other parts of the world.

In these areas, the people that live there adapt their diets to provide significant health benefits and help them live longer lives.

Nutritional therapist at Optimal Dental Health, Zara Stella highlighted two important snacks people there eat which have great longevity benefits.

Zara said: "Blueberries, raspberries, and strawberries are packed with polyphenols and anthocyanins, which protect against cellular damage and inflammation. Their low glycaemic index supports stable blood sugar, reducing the risk of age-related diseases like diabetes.

"Eat them fresh or buy them frozen which tend to be cheaper. Sprinkle them on your morning porridge, blend them into smoothies, or enjoy them as a snack."

The second snack the expert advised to have was nuts and seeds which are excellent for reducing inflammation.

She said: "Almonds, walnuts, chia seeds, and flaxseeds are excellent sources of healthy fats, protein, and antioxidants. Walnuts, in particular, are high in omega-3 fatty acids, which reduce inflammation and support brain health.

"Nuts and seeds make very handy snacks, you can add them to soups, salads, sprinkle them over yoghurt, or mix them into porridge."

Following a similar diet to those that live in the Blue Zone is a very good rule of thumb to live a longer life.

The expert said: "There is research on the populations living in the so-called which shows that there are some foods and diet principles linked to lower mortality rates, longer life and lower risk of developing chronic diseases."

She did advise people who are looking to make larger dietary changes to consult an expert first before making any changes.

Zara recommended: "While the Blue Zones offer valuable insights into dietary patterns associated with longevity, as a functional medicine practitioner, I believe in tailoring dietary advice to your unique needs."
