Nutrition for Brain Health

“The research makes it clear: Diet plays a clear and determinant role in every aspect of brain function, literally shaping our thoughts, actions, emotions, and behaviors...If your job depends on your brain, it depends on your diet.”

— Dr Lisa Mosconi

Previously I talked about how to use exercise to improve your cognitive health, today we will have a look for the ways you can heal and rejuvenate your brain with diet.

But, before we talk broccoli and chicken, lets have a quick look at what happens to the brain as we age.

The brain depends on blood flow to deliver oxygen and nutrients for neuroplastcicty, and neurogenesis. This cerebral blood flow is delivered through tiny capillaries that surround the neurons . As we age, the brain naturally experiences hypoprefusion, which is a slowing of cerebral blood flow (interestingly ... women a little less so, heheh). This diminished blood flow is associated with cell injury, cognitive impairment and alzheimers. To quickly even the gender bias above, unfortunately women are more susceptible to alzheimers than men….damn! Scientists are still hypothesising why this is…….

…… Now, when there is any kind of interruption to this flow, your neurons can be killed or injured and that causes nerve damage and restricts blood flow.

Things like any kind of head trauma can hasten this hypoperfusion and damage. Aging can thicken veins, degrade capillaries, and a poor diet will hasten this degradation further. A poor diet causes high blood glucose, and high inflammation with an intake of vegetable oils, foods you may be allergic to, processed sugars and commercially raised meat.

What can diet do for your brain?

The brain is a very hungry organ.

It uses approx 25-30% of our daily energy intake. Its made of lipids (fats) and water, and it relies on what we eat to heal and rebuild itself. If your diet is low in fats for example, the brain is unable to build new cells and facilitate its neural pathway processes. Dehydration is also very important to avoid as well.

A lot of us are eating foods that inflame our bodies, such as processed starches and grain fed meat.

Putting petrol in first is a more efficient idea

To compound this we also tend to eat diets low in anti-inflammatory foods such as oily fish and green leafy vegetable. Like persistently putting vegetable juice in your petrol tank and getting frustrated that the car is not driving like it should. To state the obvious, cars need petrol (or electricity, thank you Tesla), and humans need a range of nutrients.

Most of us and yet looking at many diets you can see that this is not happening.

Fortunately a little know how and motivation to subtly change what we eat, should be all thats needed to give our brains the best chance of getting healthy and staying healthy.

Special mention to our second brain - THE GUT

The gut’s microbiome is basically our second brain, and more and more are we finding how important it is to our brain health. Many hormones and processes we thought were initiated by the brain are actually done by the microbiota in the gut. No wonder everyone is getting on the pre and pro biotic bandwagon. We need a healthy gut (happy bug colonies abounding) to have a healthy brain. The one influences the other.

“These hundred trillion bacteria that live within your gut are so intimately involved in your brain at a number of levels. They manufacture neurochemicals, for example. Things like dopamine and serotonin. They manufacture important vitamins that are important to keep your brain healthy. They also maintain the integrity of the lining of your gut.” - Dr D Perrlmutter

Feed the gut microbiome with fermented foods such as kimchi, kefir, sauerkraut, kombucha and prebiotic foods, those high in fibre, garlic, dandelion greens, jerusalem artichoke.

What to eat for your brain

Fortunately its not that complicated to eat for brain health. If you make some small changes, you won’t have to wait till you are in the midst of a major health issue like onset dementia. If you wait till then, adjusting your diet will still make a vast difference.

If you aren’t interested in much detail, let me put this in a nutshell:

Vegetables good ………….

………….. Sugar bad

Why Vegetables?

Dr. Martha Clare Morris is an interesting lady. She is Professor of Epidemiology, Director of the Section of Nutrition and Nutritional Epidemiology in the Department of Internal Medicine, and Assistant Provost of Community Research at Rush University Medical Center in Chicago……….what a mouthful!

For the last twenty years she has been researching factors involved in the development of alzheimers as well as other health concerns for older adults. Her research found that people who ate the least amount of vegetables had the fastest cognitive decline, but that this slowed and cognition was even protected with higher intakes of vegetables.

Her research found that eating two or more servings of vegetables per day offered a statistically significant reduction in cognitive decline. Green leafy vegetables, in particular, were associated with slower decline, and people who ate green leafy vegetables at least six times a week exhibited much slower cognitive decline — researchers estimated it was like being 11 years younger in age…

Greens such as spinach and kale contain lutein and zeaxanthin. These two carotenoids are associated with faster learning speeds and applying learning and knowledge in older adults. This study showed that lutein increased thickness in areas of the brain associated with learning and slows cognitive decline in older adults.

Spinach and eggs anyone?

What about Fruit?

In her studies Dr Morris found fruit did not offer this protection, but berries did. Dr Richard Isaacs, Director of the Alzheimer’s Prevention Clinic, Memory Disorders Program, and Neurology Residency Training Program at Weill Cornell Medical College, also is a firm proponent of eating a diet full of vegetables and blueberries …thank goodness…I love a blueberry!

So all kinds of berries were protective with strawberries being the gold standard for Dr Morris and blueberries for Dr Isaacs.

Coffee

Coffee appears to play a protective role in the risk for MS, alzheimers, Parkinson’s and perhaps even early mortality. This maybe partly due to its role in reducing inflammation that is associated with reduced cognition. We certainly are all aware of its stimulating effects which is in its ability to block an inhibitory neurotransmitter in the brain, adenosine. Adenosine can reduce mental stamina and make you feel tired. It also activates our Nrf2 pathways that fight off oxidative stress and protectactivate our Nrf2 pathways, helping to fight off oxidative stress and protect against neurodegenerative diseases,

This study showed that by drinking 3-5 cups a day in midlife had a significantly lowered chance of getting Alzheimers and dementia by a HUGE 65%.

The sweet spot seems to be 2-5 cups a day. So make it organic and put that kettle on!

Green Tea

High-dose green tea extract was found to scavenge oxygen free radicals, enhance antioxidant potential, decrease lipid peroxide production, and reduce oxidative DNA damage. The high-dose group had better spatial learning and memory than saline-treated rats.

Eggs

Eggs contain lutein and choline. Choline is of particular importance for your neuronal membranes and is the precursor to the neurotransmitter acetylcholine.

Acetylcholine is important for learning and memory, as well as deep sleep. Some of the drugs approved to treat the symptoms of Alzheimer's disease, a fatal memory disorder, work by boosting levels of acetylcholine in the brain.

Unfortunately our bodies are only able to produce a small amount of choline so its very dependant on dietary intake.

Chocolate

The theobromine and polyphenols in chocolate correlate to better cerebral blood flow, improved cognition. Just make sure you eat a quality chocolate source at least 70% cacao bean and preferably higher, like 85% with low sugar.

More frequent chocolate consumption was significantly associated with better performance on the Global Composite score, Visual-Spatial Memory and Organisation, Working Memory, Scanning and Tracking, Abstract Reasoning.

Water

Our brain is mostly water, with fat coming a close second…enough said!

Kind of. Being an electrical system, the brain needs adequate water to function efficiently. The brain will react to even the smallest amount of dehydration which can cause brain fog, faitgue, dizziness, confusion and brain shrinkage. So drink those 8 glasses at least, a day. Go for quality water high in minerals and natural electrolytes where possible.

Fats

Here we need the good oils found in avocado, olive oil, MCT oil, quality fish oil. The brain can only rebuild itself with the right equipment and that is fats. Make sure your fats are from good sources and bear in mind the change that some fats go through if they become overheated such as olive oil. It will quickly become rancid and inflammatory when heated, so just save it for salads and dressings.

Protein

Quality protein is important and as we age we need a little more. It doesn’t appear as important before the age of 65 (check the research of Dr Longo), but after that, make sure to get a few serves in a day. Animal protein should be grass fed and free range. This is particularly important with red meat. Grain fed cows have meet that contains a large amount of omega 6 which is essential but not in large amounts. Grass fed cows have meat that is rich in th perfect ratio of 6 to omega 3.

“... you are what you eat ate. Yes, that’s right: you better think twice about whether your steak ate grass vs. GMO corn, your chicken ate bugs vs. herbicide-laden grains or your fish ate worms vs. pieces of other dead fish ground up with fish farm meal. Nowhere is this truer and more applicable than when it comes to fueling your brain”

— B.GreenField

Now its very important to know……

……… What to Avoid

Ideally you would want make sure your diet has none of the following:

Vegetable oils
Heated nuts and seeds
Processed sugar (always check the sugar levels in the ingredients of foods. There are a lot of hidden sugars lurking around)
Grain fed meat and farmed fish (full of omega 6, have an omega 3 capsule with these if you must eat them to balance the 6:3 ratio)
Processed starches and grains

I hope this article will inspire you to take control of your brain health and those around you.

Knowledge is power.

Don’t let the above doesn’t overwhelm you with information and do’s and don’ts. Keep it simple, its never to soon to increase your brain health. Remember Alzheimers starts more than 10 years before diagnosis is made.

Have a look through your pantry and fridge. Take note of what you are regularly eating and see how many of the mentioned foods you are there. Try writing down it down in two columns and see how it measures up. Are there more ‘avoid’ foods? More ‘eat more’ foods?

The beauty with that little exercise is we that we know where you and your household are at now. Each day,

incorporate more brain health foods and less of those to’ avoid’ foods.

Especially if you are currently feeling in a healthy state, you can take your time with this and not be too militant. If you or a loved one is experiencing brain fog, early signs of cognitive difficulty, or is right in the midst of dementia, then try everything you can to improve the food choices you make for yourself and others. Please bear in mind I am no doctor and please run any major changes past a doctor and get an ok first. For example, if you are on blood thinners then increasing fish oil can be hazardous as that also thins the blood. So you need to make sure.

I’ve included an easy PDF printout you can stick on your fridge to help remind you of what choices are best. Please download and use that if you would find that helpful.

How exercise can improve brain health

Researchers say one new case of dementia is detected every four seconds globally. They estimate that by the year 2050, more than 115 million people will have dementia worldwide.

Thats a little scary….

Dementia, alzheimers, losing brain cognition……its all around us. We ALL know someone directly or indirectly who is stricken some form of it. There are signs, posters,tv and radio shows ad nauseam regarding this epidemic.

A few weeks ago I was having a conversation with my 80 yr old aunt after our workout session. She was talking about looking into things to stimulate and help keep and even improve her brain health. Ah ha! I thought…..I’ll write some stuff down for her…..and before I knew it I was neck deep in study upon study that shows us that we can indeed have a positive effect on the health of our brain. Whether you feel terrifically cognitive, are struggling with brain fog, have onset cognitive decline or are in the middle of serious case of it, it is worth devoting bit of time to the health of your brain. I can’t think of a lot worse than going down the slippery slop of mental decline. Only fairly recently, studies have emerged showing, that as adults, we can do plenty to change the state of our brain. Previously it was thought that only children experienced could grow new brain cells. Now we know that adults are able to direct increases in neuroplasticity (changes in the brain) and neurogenesis (birth of new brain cells)

We are the only species to direct our own plasticity as adults -
Dr Andrew Huberman

Thats a huge thing! We all have the power to increase our brain capacity and repair it too …… and so do the loved ones around you …. best of all, it is FREE!

The brain is a wonderful, mysterious organ. It communicates with the entire body. It regulates our hormones and therefore our energy, movements, emotions/ mental state. It is composed of fat predominantly. Its current state is mainly due to all our PAST dietary intake, movements (physical and mental), and emotional states. Its wellbeing and future is directed by what you choose to do now in each of those things, and also its affected by our age (thats a little harder to control, but people are working on it!)

Lets address each of those areas that we have control over.

First -

Exercise.

Exercise helps the brain directly and indirectly. During exercise, blood flow, oxygen, the growth of new blood cells and neurogenesis increases, insulin sensitivity increases, the release of growth factors is stimulated and chemicals affecting the abundance and survival of new brain cells is increased

Indirectly, exercise improves mood and sleep, and reduces stress and anxiety and improves your ability to deal with stresses.

So what kind of exercise?

Aerobic

Aerobic style training like walking, and running, is shown to have a positive affect on the regions of memory and retention.

In fact walking, 30-45 minutes three times a week, is enough to delay the onset of dementia as shown by a 6 month 2006 study with sedentary people aged 60-79 years. The walking increased to increase brain volume even more than stretches and toning.

Dancing also has been found to improve cognition and neural-plasticity. If the thought of your two left feet make you shudder a little, the linked study showed that the benefits were regardless of how naturally talented or not these people were, in fact, those less gifted showed the most gain, I’m surmising that is due to increased demand on the brain to learn the moves. So no excuse, turn some music on and get movin n groovin!

Stretching

Stress, depression, traumatic brain brain injuries all shrink the hippocampus, the centre for memory and emotional regulation. Exercise has been shown to be, slightly more effective than other modalities such as medication and counselling at relieving depression. A wonderful body stretching session of yoga will increase overall brain wave activity, brain volume and activation in both the amygdala and frontal cortex.

Studies measuring mental health outcomes have shown decreases in anxiety, and increases in cognitive performance after yoga interventions

When you feel sad or stressed, try a walk or some stretches combined with deep breathing

Lifting heavy things

A 12 month study was done to see if strength training could also have significant effects to neural-plasticity. They found that training twice a week had a significant effect on this whereas training just once a week did not…..interesting

For your best brain health, it needs stimulation from a variety of movements as each part of the body is connects and communicates with various areas of the brain. As the Chinese use meridian points to influence related parts of the body, so this applies to our brain. Small movements like finger wriggling will influence certain brain neurons, and these neurons won’t be influenced without those movements. In a real world example, people confined suddenly to bed and no longer moving their lower bodies very much tend to suddenly show steep cognitive declines. This recent study found that limited physical activity decreased the number of neural stem cells by 70 % and cells that are supportive and protective to nerve cells were no longer able to fully mature. In particular it found that weight bearing leg exercises were shown to have the most benefit. Leg weighted exercise sends signals to the brain that are vital for the production of healthy neural cells, essential for the brain and nervous system.

But, is getting hot and sweaty necessary? …. kinda ….

Beta Amyloid is a protein that comprises the plaque that is found to be built up in the brains of Alzheimers sufferers This build up is caused by proteins becoming disfigured and clumping together. Something that is able to break down and prevent this build up are heat shock proteins. These heat shock proteins are activated by the heat stress that you feel during saunas and during a decent exercise session. When activated, they can be used as structural scaffolding to other proteins and prevent the beta amyloid form clumping together.

It is clear,

purposeful exercise is a vital way to keep your brain healthy. It increases neural plasticity, blood flow, increases dopamine and endorphins, increases brain volume, memory, focus. It can help the brain self regulate and calm down from stressful events. PLUS you’re burning calories at the same time! Exercise, a gift that keeps giving

Bring this into your world

Try to incorporate a variety of purposeful movement in everyday for 30-60 minutes. Get in a bit of each of the following:

Aerobic:

Long walks, riding, rowing, jogging etc

Strength:

Lift some heavy things at the gym
Do body weight moves like lunging, squatting, twisting, pushups, pulling.

Stretch.

Yoga is terrific and is also very adaptive it can be made as strong or gentle as you need it to be. There's also Tai Chi, dance, pilates and many other options available. Get inspiration from animals and see how they stretch constantly throughout the day.

A typical day might be …..

Wakeup and go for a walk for 30 mins. Then stretch, maybe some sun salutations (link) which stretch the whole body.
Later in the day either before lunch or before dinner (as this has a great effect on insulin levels) do 10 each of the following, squats, pushups, lateral lunge with shoulder press, deadlifts, calf raises, rows (link). Repeat this for 2 to 4 times through and increase weights when it feels a little easy.
Before bed do some foam rolling……

…….. Voila!
