In terms of the food we eat, we already know what our cells need but with the mixed messages we get in our daily lives, it’s worth revisiting. Here’s a recap of what & why:
For good digestion there are many other really important things to consider eg:
No refined sugar mentioned… nope, our cells just can’t use this stuff! And no additives, preservatives, chemicals etc.. Our cells will tolerate this ‘foreign fuel’ or toxins for awhile, then… one day they’ll just start ‘breaking down’, we might develop headaches, lethargy, or even a digestive disorder or chronic disease.
Cram the good stuff in and without thinking about it you’ll naturally stop eating the nutrient dead stuff – do it – you’ll surprise yourself.
This description just scrapes the surface of our beautifully complex digestive system and how to get out motors runnin’.
The important thing is, ‘we are not only what we eat – but what we digest (absorb)’…
Two great references for improving digestive health are:
Jordan Rubin, ‘restoring digestive health’ or ‘the makers diet’ and Elizabeth Lipski, has written a number of books specifically on this topic. There are many others…
I recently chatted with Dr Sarah McKay an Oxford University-educated neuroscientist, science writer, and the creator of neuroscience blog Your Brain Health – www.yourbrainhealth.com.au. Sarah is a wealth of knowledge when it comes to understanding our brains better. I am delighted to share with you her top ten tactics for improving our brain health and wellness.
Thank you Sarah!
‘I’m delighted that Kate invited me to write a guest blog post for her today.
Over on my blog I break down neuroscience research into simple, actionable steps to improve brain health and wellbeing. I have a passion for evidence-based medicine, the scientific method, and connection and conversation. This means that I try to make it easy to understand the best available neuroscience and clinical eviden
ce on brain health. I write about neuroscience and how the latest findings relate to our everyday lives. There’s no scientific jargon, no tricky-to-understand data—just simple explanations of the evidence.
Just as a quick note for readers of this blog, I mostly write about the adult brain and even touch a little on brain aging and dementia risk reduction. But much of the research is common sense, and applies to children too’.
1. UNDERSTAND
Your brain is not hard-wired. The connections —synapses— between neurons are ‘plastic’ and can change. The changing strength of connections is called neuroplasticity, which underlies learning and memory. When you form new memories you are rewiring your brain. Neuroplasticity is a lifelong process.
2. NOURISH
The foundation of a healthy brain is a healthy well-nourished body. Neuroscience points towards a Mediterranean-based diet of mostly plants (vegetables, fruit and legumes), fish, some meat, olive oil and nuts as optimal nourishment for brain health. Wine and coffee in moderation (yes, really! Just not for the kids!) prevent cognitive decline and memory loss.
3. MOVE
Regular exercise keeps your brain healthy too. Neuroscience shows that people who are the most physically active have a lower chance of developing dementia. Exercise decreases cardio-vascular disease, inflammation and promotes the birth of neurons. Try to get 30 minutes of heart-rate raising exercise, or walk 10,000 steps daily.
4. CALM
Not all stress is bad, but chronic stress and anxiety can change the wiring of our brains. People prone to psychological distress experience brain ‘fuzziness’, are at risk of developing mental health problems, and experience more rapid cognitive decline. Too much cortisol (a stress hormone) prevents the birth of new neurons and causes the hippocampus (the brain structure involved in learning and memory) to shrink, reducing your powers of learning and memory. To de-stress – do something pleasurable. Maybe even learn to meditate. The most pleasure is to be found in doing something you’re reasonably good at and that also poses some degree of challenge.
5. CONNECT
Having friends and social connections helps you live longer and keeps you healthier. Socialising reduces the harmful effects of stress and involves many cognitive functions such as thinking, feeling, sensing, reasoning and intuition. Mentally stimulating activities build up a reserve of healthy neurons and promote neuroplasticity. Have a good social support network has the equivalent health benefits as giving up smoking! 
6. SLEEP
Sleep is essential to your body’s overall wellness, both physically and emotionally. Sleep improves cognitive function and psychomotor performance (the brain telling the body to move). Even a brief afternoon nap considerably enhances short-term memory and mood. Memories cannot become consolidated in your brain without sleep. Adults should aim for 8 hours a night, but more can slow your cognition. Teenagers need just as much sleep as toddlers!
7. FOCUS
Not all forgetting is bad. Your brain forgets information it doesn’t need so you can focus on what information you need to retain. Pay attention to what you want to remember. Practice focussing on tasks, and structure activities so you can mindfully attend to each step. Paying attention when we form a new memory transfers it from short-term to long-term storage.
8. ORGANISE
Always losing your keys or forgetting dates? Organise your life and help your brain to remember. Use external memory aids such as sticky notes, calendars, or smart phone alerts. Nominate a place to leave your keys. Stop leaving your memory to chance. Emotional memories are the strongest — link names and faces with vibrant stories you tell yourself (in your own mind!).
9. CHALLENGE
Adults who regularly challenge their minds and stay mentally active throughout life have healthier brains. Think about trying activities that combine mental, social and physical components. Mental activity should be regular, reasonably complex, and varied – doing the odd crossword is not enough. Your mental activity should involve learning something new. You have the same ability to learn that your children do.
10. BELIEVE
Do extraordinary things! Set fantastic, passionate goals and work like crazy to achieve them. Don’t retire — follow your bliss. Adults who challenge their minds and stay mentally active throughout life have healthier brains. You’ll make memories worth remembering too!
From these 10 simple tactics, what will you do more of to take your brain health to new levels and protect it as best you can, both for you and your family?

Last weekend I went along to Ian Gawler’s one-day workshop in Denmark, Western Australia. For anyone unfamiliar with Ian, he is an Author & Advocate for mind, body, medicine and meditation. Almost 40 year ago, while working as a Vet he was diagnosed with Cancer, Osteosarcoma, a form of bone cancer. In 1976 doctors gave him weeks to live. After following conventional treatment Ian adopted a regime of intense meditation, (up to 5 hours each day)! He followed the Gerson Diet and an intense program of research and personal development. In recent years controversy has surrounded Ian for various reasons, that aside he has survived a terminal diagnosis of Cancer and is alive and well today. I was intrigued to learn more, and especially about the power of the mind and his intense approach to meditation, which appears instrumental in his recovery.
There were 6 key messages I took away from the day:
Regular meditation isn’t easy, it takes work and practice, but now having this knowledge – why wouldn’t we commit to taking at least 5 minutes out in our day and start the process of rewiring some of those hard wired neurons. In doing this we lower our stress levels, increase our immunity, activate happier thoughts, positive energy and perhaps some much needed clarity and perspective. It seems to be a fundamental strategy to put us back in the drivers seat and take back control or our own health.
Want to get started, but don’t have time, or not sure how? One of the simplest ways to start, even if you take just 5 minutes, is to find a comfortable spot to sit, then place continuous thought on one subject e.g. to focus on your breathe or the sounds you can hear off in the distance, really listen out and aim to be present in the moment. When I take even 5 minutes to stop and centre my thoughts, I notice that afterwards my energy levels have lifted, my mind is calmer / clearer and I am more productive. Meditation, or even just being still and centereing my thoughts is something I’m doing more of and aim to build up the amount of time I dedicate to it.
Ian also shared an entertaining cricket analogy, ‘In 1874, the first ‘testicular guard’ or ‘box’ was used in cricket. In 1974, the first helmet was used’! Now that’s something to get our minds around…
