While genetics play a role in longevity, lifestyle changes may help reduce biological age

Longevity has dramatically increased over the past century owing to significant scientific advances.

In a promising development, recent findings published in Nature suggest that lifestyle may be up to 10 times more important than genetics in determining life expectancy.



Those seeking longevity are generally advised to incorporate as many whole foods as possible into their diet.

But Dr Taz Bhatia, a board-certified physician and holistic doctor in Atlanta, recently listed eight specific dietary habits that could have long-term benefits.

In a TikTok post, the doctor claimed that the longevity superfoods can help with "ageing backwards".

She added: “What you eat plays a huge role in cellular health, skin elasticity, and longevity."

Dr Bathia's list included instructions on how often to consume the foods for optimal effects.

  • Avocados - rich in healthy fats and antioxidants that support skin hydration and brain function - eat one every other day.
  • Blueberries - packed with antioxidants that fight oxidative stress - aim for ½ to one cup daily.
  • Salmon - loaded with omega-3s for brain and heart health. Try two to three servings per week.
  • Sweet potatoes - a beta-carotene powerhouse that promotes glowing skin and immune health. Have one every other day.
  • Almonds - A great source of vitamin E and healthy fats to protect against ageing. Eat 10 to 12 daily.
  • Green tea - contains polyphenols that support metabolism and skin health. Drink two to three cups per day.
  • Tomatoes - high in lycopene which protects skin from sun damage Eat one medium tomato or five cherry tomatoes daily.
  • Dark chocolate (70 per cent or higher) - is rich in flavonoids that improve circulation and reduce inflammation. Enjoy one to two small squares daily.

Not only do dietary habits like these reduce the risk of developing serious conditions like type 2 diabetes, but they also support bone health.

Another doctor recently told GB News that patients who live the longest primarily consume natural foods.

"The patients I see that have lived the longest eat primarily natural foods: lots of fruits, lots of vegetables, dairy, meat and fish," explained the medical doctor from The Herbal Doctors.

"But the key here is the lack of refined, processed foods and snacking - very little snacking and very little processed foods."

Founder of Oxford Healthspan Leslie Kenny also GB News how she achieved the remarkable feat of reversing her biological age while tackling autoimmune conditions, all through a “longevity lifestyle”.

Although Leslie will soon turn 60, biological tests suggest her body is that of a 21-year-old.

She explained that through autophagy, she successfully addressed several of her health concerns and reversed her biological age in the process.
