Diet is a massive factor in leading a long and healthy life. Choices we make now could have an impact for years to come – so making sure that they’re for the better is important.

According to one expert, three simple beverages could help you live to 100. American longevity researcher Dan Buettner says: “It is not natural for humans to be drinking the milk of another animal any more than it would be to see a dog suckling a pig. It’s just weird.”

He promotes a diet based on Blue Zones – regions where people typically live long lives and often exceed their 100th birthday. These areas include certain villages in Japan, Greece, Italy, and Costa Rica.

Buettner noted that inhabitants of these zones usually consume only three types of drinks, reports the Mirror. He added: “By and large, [people in Blue Zones] are not drinking cows milk at all. You see a little bit of sheep’s milk cheese, pecorino and goat’s milk cheese in the form of feta. For the most part, when it comes to what they drink, people in Blue Zones drink water, teas and wine.”

Water is crucial for our bodies to function correctly, offering benefits beyond just hydration. It regulates body temperature, aids digestion, maintains normal blood pressure and balances our electrolyte levels.

Dehydration can lead to skin damage, resulting in it feeling rough and itchy as well as appearing wrinkled. The NHS recommends that healthy adults should aim to consume between six to eight glasses of fluid a day (approximately two litres) – or enough so urine is a clear pale yellow colour.

Tea – with so many varieties – has many natural health benefits. Certain teas have been associated with lower cholesterol levels, improved heart health, and immune system enhancement, among other benefits.

Some teas have gained popularity for their mental health-boosting properties. Brews including chamomile, matcha and lavender can help reduce stress and anxiety.

Wine might surprise some as a ‘healthy’ beverage. However, it’s important to note that moderation is key in these Blue Zones as well.

The health benefits of this alcoholic drink are largely attributed to its high antioxidant and polyphenol content derived from plant-based ingredients. These properties contribute to maintaining good heart health and balancing the ‘good and bad’ cholesterol levels in the body.

The NHS recommends that people drink no more than 14 units of alcohol per week, spread out over three or more days. This is considered low-risk drinking, but there is no safe level of drinking.
