The healthiest diet in the world

What is the healthiest diet in the world? It’s a contentious question amongst ‘experts’ who debate this topic with a certain amount of ‘cognitive dissonance,’ generally quoting data that backs up their beliefs or dietary leaning (and if anything goes against their beliefs, they generally diss the study by focussing their attention its flaws). I recently read a comment from a long term paleo enthusiast who after studying ‘health longevity’ had begun to question that he was indeed, on the right track. He was concerned that the longest (and healthiest) living communities ate very little meat (he claimed that pasture raised meat formed 50% of his diet), that many ate grain, dairy and all ate legumes and lots of vegetables. He asked if anyone could offer an example of a long living, healthy culture where meat, featured heavily in their diet. The backlash was not pretty, lots of ‘cognitive dissonance’ but no answers to his concern.

So upon reading this debate, I thought I might share my thoughts on what I believe the ‘healthiest diets’ have in common. Food culture is a topic that has long interested me, I think there is a lot to learn about the power of food from investigating this topic. I’ve been fortunate enough to travel to many countries in my lifetime and immersing myself in their way of eating has been one of my life’s great pleasures. I’m not a traveller that seeks out health cafes, instead preferring to eat the way the locals do (the exception to this may be travelling the more Westernised countries)!

There are vast differences when you compare traditional ‘healthy’ diets from around the world; the Japanese fare well on a diet of rice, soy, seafood and seaweed (sans wheat and dairy). The Mediterranean countries thrive on a diet of fruit, vegetables, whole-grains, legumes, nuts, cheese, bread and olive oil. Then there’s the French Paradox which really has nutrition ‘experts’ scratching their heads. Despite the rich foods they eat (lots of butter, dairy, bread), the French have some of the lowest obesity rates in the developed world. Having said that, I have visited France 12 years apart and couldn’t believe how much it had changed (so many more franchises/fast food eateries) had popped up so I’m predicting this may change.

So here are a few of my observations of what the diets of people living in the healthiest, longest living countries and communities have in common…

They eat lots and lots of seasonal vegetables. We know they are good, we all need to eat more.

They practice portion control
This is definitely one of the reasons the French are able to maintain a healthy waistline. They don’t snack and they don’t overeat the way most Western cultures do.  Healthy cultures practice ‘genuine’ moderation – I have to add that so many people fool themselves into believing they practice moderation (especially when it comes to sweet stuff) so it’s a word I try to avoid, but couldn’t find a better way to express myself here.

They eat seasonally and locally
This is a given in the many longest living, remote communities, but even the French and many other industrialised ‘healthy’ countries shop only at their local market or fresh produce store. Such a simple way to ensure good health – Local – Seasonal.

No processed crap
They don’t eat highly-processed ‘sterile’ foods. It is fascinating that when a culture ventures away from their roots and replaces an unprocessed diet with processed, how their health and longevity declines. There are many, many historical examples of this.

Share the pure pleasure
Most healthy eating cultures make meals an event. They stop and share and enjoy food together as a family or community, instead of scoffing a bowl of cereal at the kitchen bench or in front of the telly, calling it dinner. There have been many studies that have demonstrated the importance of community and relationships on both mental and physical health. Again, so simple!

Don’t ignore genes
They eat according to their culture. We are all individual and I can not stress enough that a ‘one diet’ fits all approach is not healthy. Remember, most of the popular diets and food fads interests are firmly fixed upon making money so they will always and passionately plug ‘their way’ as the only way. This is simply not the case. For example; I used to see this a lot with Asian patients – they really didn’t thrive on a Western wheat dominated diet, a gluten-free rice-based diet suited them way better.

Less meat
They don’t eat heaps of meat. Most cultures with good longevity certainly don’t eat meat every day. They do well combining vegetarian sources of protein, but animal sources are often only eaten as part of a celebration or significant event.

They are never ‘on a diet’
They don’t deprive themselves or exclude basic food groups. I’ve written about food stress and why it just won’t serve you here. Food restriction and the stress associated with it is a very vicious circle.

Move it or loose it
They move, gently and often – they don’t hit the gym twice a week, instead making movement part of their everyday life.

Pretty simple huh? Sadly, since there are no money-making opportunities and no glamour attached to anything this straight forward, you are not likely to hear about basic nutrition from the ‘health’ promoters, whose livelihoods depends on many people following the ‘hype’.

Okay, so over to you…do you know a centenarian or do you share my fascination with food history or health longevity. What have I missed, can you contribute in any way? I’m no expert here, these are just my thoughts on the matter so I’d love you to share your perspective.

  • I’m halfway through listening to an interesting Ted Radio Hour episode called Fountain of Youth (from May 22nd if you’re looking for it) that backs up everything you’re saying. Include social connectedness, a sense of purpose and delete the word ‘retirement’ and you’re on your way 🙂

    • Thanks Robyn. In my post grad I did a unit on ageing and yes, social and spiritual connectedness is huge. Everyone thrives with a purpose in life, as essential if not more so than food. Thanks for contributing, G x
      PS – I love TED talks too!

    Great to read this Georgia…I think you’re spot on. However, as a male, and someone who likes to lift heavy things, I find I need more protein than most. I find that unless I eat concentrated sources of protein including lean meat, I can’t get enough while keeping kilojoules in check. Lean meat – especially kangaroo – is a staple for me. It seems to keep my body lean while building and maintaining muscle mass.

    • Thanks Nolic. Yes everyones needs are very different and it’s great that you have recognised what fuels your body best. Kangaroo certainly is a very sustainable form of protein, not one I have had the chance to explore as yet. Appreciate your contribution, G

    • Thanks so much Sarah, glad you enjoyed it and that you and your family are enjoying my recipes. Go local !! G x

  • Petrina

    I work for a french company so have many French to study. I agree with you, they do not snack. I also notice they always have their lunch later (after 1pm), and never at their desks.

    • Yes Petrina, it’s such a shame we don’t have a solid food culture like the French. Also glad I was right with that info – ha ha! G x

  • Oh Georgia – I absolutely LOVE this article. You’ve summed it up perfectly! I wholeheartedly agree with your observations around healthy eating and lifestyle. There really is no one way to eat well. Portion control, daily movement and a focus on fresh vegetables is definitely key in my opinion. Brig x

I have spent alot of money on courses about healthy eating and recipe books but your books have covered it all and my little man enjoys the snacks etc. Wish I would have found you earlier “. Brooke

“I just want to say a huge thank you for your amazing website and information. I’ve never liked cooking and never got excited by my ‘healthy’ cooking. My husband is even worse and if he could, he would just eat beacon and eggs every morning and steak every night. He hardly ate any veggies. Since I found your website I have gone through almost every recipe. My husband is loving every meal as well – even meat free Monday, and he’s taking left-overs to work for lunch (honestly, who thought that could be so hard?!)” Rose
