What Is The Blue Zone Diet?

26th January 2023

26th January 2023

By Adele Webb

We all want to live a healthy and prosperous life – right? This world is a rollercoaster and yet we are always seeking new ways to improve our lifespan to ensure we reach the ripe old age of 100. This is exactly what Dan Buettner, a National Geographic explorer, questioned with his Blue Zone Diet discovery! The term ‘Blue Zone’ may be unfamiliar to some, but what was revealed is fascinating, not to mention uplifting.

In 2000, Buettner set about his quest to find the secrets to longevity and came back with 5 places in the world in which the residents lived longer and happier lives…and still do today. Okinawa in Japan, Sardinia in Italy, Nicoya in Costa Rica, Ikaria in Greece, and Loma Linda in California were all branded the places with the world’s longest-living people due to their healthy habits.

There is high speculation as to whether our genes play a role in how long we live, however the Danish Twin Study in fact established that on average, only 20% is influenced by genes, and instead, it is all down to what we consume and the activities we partake in, as well as our frame of mind. The 5 chosen Blue Zone countries each have their own habits which slightly differ between them:

  • Okinawa, Japan – Okinawans grow their own gardens which results in several things: they keep active through the gruelling nature of garden upkeep, gardening is a natural stress relief - so their minds are kept healthy, and they also grow their own fresh produce to help keep their bodies in check. Homegrown produce is always better!
  • Sardinia, Italy – Sardinians limit their meat intake and only consume it on Sundays and special occasions. In return, their diet is focused on whole grains, vegetables, beans, and fruit, and they consume these for most of their meals. Surprisingly enough, they also indulge in a glass or two of red wine daily – who would have thought, huh?
  • Nicoya, Costa Rica – Nicoyans banish the heavy pre-bed feasts and delight in a light, early meal instead, with diets centering around corn, beans, and squash. Wholesome and hearty!
  • Ikaria, Greece – Ikarians stick to the Mediterranean diet which means plant-based foods are a focus here: vegetables, legumes, fruits, nuts, seeds, herbs, and spices are consumed on the daily. Also, due to their Orthodox Christian beliefs, they frequently partake in fasts as their religious practice.
  • Loma Linda, California – Lastly, the community who live in Loma Linda follow a vegetarian or pescatarian diet and mostly try to limit sugar, salt, and refined grains.

Blue Zone Food Guidelines

Although there are variations between them, it was noted that these places collectively shared similarities in what they put into their bodies. We know you are too intrigued as to how you can switch up your own eating habits to provide a longer life…so follow this Blue Zone Food Guideline to start your journey to a prosperous adventure.

  1. Plant Slant

As a rule of thumb, you need to ensure that 95% of your food group is from a plant or plant-based product. This means keeping your favourite fruits and vegetables stocked up at all times – this is the best way forward. Think apples, oranges, broccoli, carrots…you name it! Just eat the rainbow and you will be where you want to be. Fresh produce is not always obtainable, we get that, so as a substitute, frozen vegetables are also fine. Many oils also derive from plants, so switch out animal-based fats like butter and cook your veggies with olive oil. Evidence has supported the consumption of olive oil as it lowers bad cholesterol and increases the good. Just don’t go overboard here.

  1. Limit Meat

Only eat meat twice a week (or less if feasible). Your limited meat intake should be focused on either free-range chicken, family-farmed lamb, or pork, with meats raised industrially swiped to the side. Processed meats are a massive no here…say goodbye to your beloved hot dogs and sausages. Most of the Blue Zone people only ate a small amount of meat, with these being their own pig or goat for example. If you would prefer to not consume meat at all (you go), then there are plenty of plant-based protein alternatives on the market that can take their place. We suggest lightly sauteed tofu…cooked with a little bit of olive oil – perfection!

  1. Go Whole

This next one can be tricky in today’s day and age. It is certainly easier to pick up the nearest convenient product you can find, but eating whole foods is admired here. The general consensus is to avoid factory-made foods, avoid foods wrapped in plastic, consume products made with no more than five ingredients, and definitely banish pre-made ready meals. For guidance, take a gander around your local farm shop – I’m sure there will be plenty of whole foods to sink your teeth into there.

  1. Slash Sugar

As we all know…sugar is a no. It’s as simple as that. Consume no more than seven added teaspoons a day – the Blue Zone locations mainly consumed foods with no added sugar and sweetened their tea with honey instead of spoonfuls of the sweet-tasting soluble carbohydrates - guilty? Obviously you cannot avoid this addictive stuff completely, and naturally occurring sugars in fruit are fine, just make sure to throw away your much-loved cakes, cookies, and chocolate bars to overcome sugar addiction – it’s the thing of the past. We suggest only consuming sweet foods on celebrations, think birthdays and Christmas. You will also look forward to it so much more!

  1. Daily Beans

Beans, beans they are good for your heart…well actually these small morsels are the building block of Blue Zone diets. Black beans in Nicoya, white beans in the Mediterranean, and soybeans in Okinawa, beans are consumed on the daily. You may or may not know that they are in fact made up of 21% protein and 77% complex carbohydrates which results in slow and steady energy instead of rapid spikes from refined carbohydrates. For guidance, ensure your cupboards are always fully stocked with a variety of cans – these can be a fantastic addition to salads, and for those who love hummus, make your very own with chickpeas, or try chickpea soup! Yes, these count.

  1. Beverage Rule

The Blue Zone beverage rule is straightforward: drink coffee for breakfast, tea in the afternoon, and wine at 5pm – with water at arm’s reach throughout the day. Never consume fizzy drinks, including the diet variety (sorry). Why not try our Detox Booster tea – full of healthy ingredients, this easy-to-use powder can support your immune system and maintain a healthy PH balance. For water, it is recommended to quench with seven glasses daily with studies saying that amplified hydration heightens the blood flow and reduces the chance of blood clots. As for coffee and red wine: coffee is said to lower rates of dementia and Parkinson’s disease (despite the caffeine scare), whilst red wine has been found to help your body absorb antioxidants.

Super Blue Foods

At least three of The following foods and drinks should be integrated into your daily Blue Zone diet:

  • Greens – like kale, spinach, fennel tops, and chards
  • Beans – lentils, black beans, pinto beans
  • Nuts – almonds, peanuts, sunflower seeds, cashews, all are good!
  • Sweet potatoes
  • Olive oil – extra-virgin is usually the best here
  • Oats
  • Fruits
  • Green matcha or herbal teas – there are plenty to choose from!
  • Turmeric – either as a spice or tea

Summary

Whichever walk of life you are on, as the year 2023 starts its ascent, I’m sure we are all on the lookout for ways we can better ourselves both physically and mentally whilst ensuring the longevity of our journey. The Blue Zone Diet is both aspiring and easy to follow, with the benefits apparent in all five locations: Ikaria, Okinawa, Sardinia, Nicoya, and Loma Linda. Small changes are the best step forward, switching up your lifestyle slowly but surely will provide a world of good. Let’s be inspired by other cultures and adopt their happy nature. Life is for living after all right?

Why Creatine is Having a Moment
If you said “creatine” ten years ago, most people would’ve pictured a guy at the gym, slamming a protein shake the size of a fire extinguisher. Fast forward to today, and creatine is gaining more traction than ever – but not for the reasons you'd expect. It’s not just about size or strength anymore. It’s about mental sharpness. Recovery. Longevity. Hormonal support. Healthy ageing. And while it’s long been the most studied supplement in sports nutrition, new research is changing how we think about it – and who it’s for. Let’s break it down. First: What actually is Creatine? Creatine is a naturally occurring compound your body produces (and you get in small amounts from red meat and fish). It’s stored mostly in your muscles and brain, where it helps regenerate adenosine triphosphate (ATP) – your body’s main energy currency. In plain English? It helps you produce energy faster and more efficiently. That’s why creatine’s been a staple for athletes and weightlifters for decades – because it enhances performance, power, and recovery. But that’s just scratching the surface. Reason 1: The science has evolved The benefits of creatine aren’t limited to physical performance anymore. In recent years, researchers have started to uncover its role in cognitive function, mental fatigue, and neuroprotection – especially under stress or during sleep deprivation. A 2021 systematic review published in Nutrients found that creatine supplementation “may improve short-term memory and intelligence/reasoning” – particularly in people who are sleep-deprived, stressed, or ageing . Another study in Psychopharmacology found that supplementing with creatine significantly improved working memory and information processing speed in healthy adults . We're also seeing promising links between creatine and age-related cognitive decline. There’s emerging evidence suggesting it may support brain health in older adults – acting as a protective buffer against neurological degeneration . In short: creatine is no longer just a “performance” supplement. It’s increasingly viewed as a daily health essential – especially for your brain. Reason 2: Women are in – and rightly so Historically, creatine marketing catered almost exclusively to men. The packaging was aggressive, the messaging all about muscle mass, and there was a persistent myth that creatine would cause bloating or bulkiness. It’s no surprise women stayed away. But now? That narrative is breaking down fast – and the science is doing the talking. Studies show that creatine may be especially important for women – particularly through perimenopause, menopause, and beyond. Research published in Nutrients highlights that creatine supplementation can support muscle strength, bone density, and mood regulation in women during and after menopause . It’s also been shown to help maintain lean muscle mass and support cognitive function during hormonal fluctuations – making it a powerful ally for long-term wellbeing. And no, it won’t make you puffy. The “bloating” myth comes from a misunderstanding: creatine draws water into your muscle cells (where it belongs), which actually supports performance, hydration, and cell integrity. This isn’t about bulking. It’s about feeling energised, strong, and supported in your body – no matter your life stage. Reason 3: It’s not just for the gym anymore The old creatine image was all about barbells and bench presses. But modern life demands more than just gym gains. We want to feel good, stay sharp, move well, and perform in life – not just during workouts. Creatine helps with all of it. Whether you're training hard, working late, chasing your kids around, or trying to keep brain fog at bay – creatine supports energy production, improves recovery, and sharpens your thinking. Even endurance athletes, office workers, and biohackers are getting in on the action. One study found that creatine enhanced oxygen consumption and reduced fatigue during long bouts of aerobic exercise . Put simply: creatine helps you show up as the best version of yourself, wherever life takes you. Reason 4: You’ve got options now Here’s the good news – the supplement industry is finally catching up. Gone are the days of industrial-sized tubs and confusing dosing instructions. At Innermost, we’ve reimagined creatine in a way that’s clean, purposeful, and fits into real life. At innermost, you’ve got two simple options: The Power Booster – our pure, pharmaceutical-grade creatine monohydrate. Zero additives. Just high-quality creatine in its most effective form.The Strong Protein – our intelligent protein blend for strength and recovery, with creatine built-in alongside nootropics, anti-inflammatory ingredients, and functional adaptogens. One blend, multiple benefits. Both options are designed for people who care about their health, performance, and clarity – not just their biceps. FINAL THOUGHTS Creatine isn’t new. But the way we understand it - and who it’s for - absolutely is. It’s not just about muscle. It’s about mood. Memory. Mental sharpness. Movement. And supporting your body through every season of life. Whether you’re lifting, learning, leading, or just looking to feel a little more like yourself again - creatine could be one of the smartest additions to your daily routine. Read more
The Dangers of Silica
Ever opened a sachet of hydration powder, only to have a puff of dust cloud waft up into your nostrils? You're not imagining it. Most electrolyte drinks on the market contain silica - a synthetic anti-caking agent added to keep powders dry, free-flowing, and easy to manufacture at scale. It’s one of those behind-the-scenes ingredients that doesn’t need to be there… unless your priority is speed and profit margins, not people. Let’s break this down. What is silica? Silica (aka silicon dioxide) is a compound found in sand, quartz, those little sachets that come with new shoes, and yes - in many processed foods and supplement powders. In this industry, it’s added to prevent clumping and help powders flow smoothly and zip through high-speed packaging machines. It’s not added for your health. It’s added for efficiency.  And here’s the thing: silica is not inherently dangerous when eaten in small quantities — it occurs naturally in some foods, after all. But when it’s inhaled, it’s a whole different story. Let’s talk about silicosis Silicosis is a serious lung disease caused by breathing in fine particles of silica.  Many of these powders are so bone-dry and ultrafine that you can’t help but inhale a bit when you open a sachet. And while regulators have deemed it “safe” for consumption, they’re not telling you what happens when you’re breathing that dust in day after day. We think it matters. Why it’s used anyway (and why we don’t). Silica makes life easier for big manufacturers. When a powder is dry and ultra-fine, it runs like a dream through industrial machinery. That means more sachets filled per minute, fewer machine stoppages, and higher production yields. In other words: cheaper, faster, more profitable. It’s what most brands do - especially the ones backed by big investors who demand a return on their money. That’s just the way it works. Innermost is proudly independent. Something we don’t talk about often enough is that we’re 100% self-owned. No outside investors. No pressure to cut corners to meet someone else’s margin goals. That means we get to put your health - not shareholder value - first. We created The Hydrate Blend to be 100% natural, functional, and free from synthetic fillers. No nasties. No shortcuts. And absolutely no silica. Yes, it might cost a little more than the cheapest stuff on the market - but it’s better for your body, and your lungs. Let’s call it what it is. Most people will never think twice about inhaling the powder that wafts up out of their electrolyte powder. But we do. Because we know the supplement industry loves to hide behind shortcuts and call it innovation. Loves to throw in cheap ingredients because they’re easier - not because they’re better. Loves to race to the bottom on cost while pretending they’re leading on health. That’s not us. That’s never been us. We’re not here to cut corners. We’re here to raise standards. And sometimes that means doing things the hard way - like formulating a hydration product without any silica in it, knowing full well it’ll be way harder to do. But your health is worth the effort.
