Quite a few intelligent people extrapolate a rather apocalyptic future for humanity. Whether we nuke ourselves, run out of resources, become infertile, overtaken by AI robots or are struck by a meteor, some go so far as to recommend space travel to secure humanity’s future.

The two fundamental problems

My ponderings conclude that there are two fundamental problems – and one essential requirement to solve them. The first problem is corruption, primarily driven by greed. The second is a lack of design, for truly sustainable living in the areas of health, ecology and economy. The essential requirement to solve both of these problems is benevolent intelligence – that is, intelligence for the benefit of all, with the right motive and not driven by greed for money, power or status.

Here lies a key problem to add to the list of dwindling resources, pollution and war mongering, and it is the undeniable decline in that unique attribute which makes Homo sapiens dominant in the world, perhaps even the universe – that is his intelligence. IQ, brain size and mental health are all in rapid decline. Scandinavian research says IQ is falling by about 7% a generation. Brain volume, based on skull size, has decreased by 20% in the last 20,000 years or so. Rates of mental illness and neurodegeneration are escalating across all ages and seemingly in all countries.

We do not just need a few super-bright people, although that helps, if the populous in general is dumbing down. That’s a recipe for dictatorship. We need the majority to ‘wise up’ – including both the young, because they are the future and the elders, because they hold knowledge from experience. (I like Isabelle Allende’s – the best selling Chilean American novelist – definition of experience as ‘what you learn just after you need to know it’.)

At risk of losing all that we have learned…

In China for example, the ‘silver haired’ economy of people over the age of 60 comprises 300 million people. The tragedy of course, is that many are drifting into dementia and losing the memory of all that has been learned.

That is why, along with peace, climate, ecology and sustainable energy activism, the mission of foodforthebrain.org is to protect and promote intelligence and mental health and must expand to become global if we are to survive as a species.

The acceleration of societal change in the digital age, compared to the industrial age, will be rapidly surpassed by the age of artificial intelligence. Resistance is futile. For us, on a mission to protect and promote mental health and enhance intelligence, AI opens up the possibility to make our COGNITION programme available to all, in any language, and to learn from the experience of thousands, what specific messaging really helps drive positive behaviour change to promote mental health and intelligence.

Of course, we would like all this taught in schools and prioritised in healthcare but we cannot afford to wait for the corrupted governmental bureaucracies to paradigm shift. So called healthcare, in most countries, remains deeply in the claws of big Pharma and big Food. 

Putting prevention before profit is not even in their futuristic sights, whether one votes left or right. In the UK, for example, the NHS remains the fastest growing failing business, with no plans for preventing disease. The latest person put in charge of prevention, Professor John Deanfield, is paid by and has shares in, pharma. He considers prevention to be achieved by more drugs to more people earlier, despite the fact that the crippling diseases we have created in the 21st century were never caused by a lack of drugs.

—

Prevention before profits – let’s do it together!

Hence, we have to ‘do it ourselves’, direct to the public, people telling people, funded by people – citizen science and education at its best. Our impact may be small to start with, lacking significant funding or buy-in from progressive countries but both are increasingly likely as the mental health meltdown becomes epidemic. The cost of dementia crises will linger and the breakdown in children’s mental health, upon which our future depends, looms as catastrophic. Who will care for the billions with neurodegeneration? This is not a problem that is going away.

China is a case in point. There are 300 million people over 60 and the estimated annual cost of dementia will exceed $1 trillion in the next decade. Do we ‘make Britain dementia friendly’ and pour yet more money into our failing health services or do we end dementia? The scientific fact is that less than one in a hundred cases of Alzheimer’s are caused by genes. Theoretically, 99 percent could be prevented with nutrition and lifestyle changes. It isn’t actually that difficult.

Global mission

This is not a pipe dream. We can do so much together to change this – anything is possible!

Next year we are targeting 18 million over 60 year olds in China with the blessing and collaboration of the former minister and vice minister of health, both now ‘silver-haired’. What we are doing – personalising and popularising prevention – is doable on a global scale, precisely because we are in a digital age. AI allows us to break down the barrier of language.

Read part one here to learn about the first two ‘horsemen’ – Brain Fats & Methylation.

—

Few people realise the catastrophic decline in mental health that has occurred over the past 50 years.

‘Brain health conditions have become a global health emergency,’ according to the Federation of European Neuroscience Societies last year (1).

The big question is: why?

—

Introducing the four horsemen (recap)

I’m proposing that there are four main biological drivers of our demise which I’m calling the four horsemen of the mental health apocalypse: a lack of brain fats, messed up methylation, loss of glucose control and excessive oxidation.

The first two – brain fats and methylation – are vital for the integral structure of neuronal membranes.

The second two are vital for the function of brain cells, supplying fuel and coping with the oxidant ‘exhaust fumes’ of energy metabolism.

—

Brain fuel

While omega-3 and B vitamins literally build a healthy brain, it is glucose and ketones that fuel it.

As a result of this process, oxidants are created which age the brain through the process of oxidation. Of course, oxidation can also occur through external causes, which is why smoking and air pollution are also established risk factors for Alzheimer’s.

Which leads us to the next two ‘horses of the mental health apocalypse’: the brain’s fuel supply and antioxidant protection. The brain consumes more energy than any other organ of the body. Neurons can only run on glucose or ketones. The irony is that the consequence of eating too many carbs and sugar is that the brain develops insulin resistance – effectively blocking the glucose from entering the mitochondria within the neurons. Starved of their energy source, we experience the consequences as mental fatigue and forgetfulness. According to Dr Robert Lustig,  Emeritus Professor of Pediatrics at the University of California, San Francisco and a member of our Scientific Advisory Board, “This cognitive decline starts young. Cognitive decline in overweight children is associated with a high GL diet (1), and adolescents with metabolic dysfunction, driven by a high GL diet, have been shown to have shrinkage of the hippocampal area of the brain, as well as other structural changes and cognitive deficits (2).” This particular study showed actual shrinkage of the Alzheimer’s associated area of the brain in teenagers with metabolic syndrome as a consequence of too much sugar and ‘white’ carbs. The youngest age of an Alzheimer’s diagnosis, which requires proof of shrinkage of the hippocampal area of the brain, is age 19, in a young man in China who had no genetic risk factors (2).

It’s a biochemical storm.

As well as the fuel starvation that insulin resistance generates, the converse of blood sugar spikes, create Advanced Glycation End-products, or AGEs, that literally damage neurons. This ‘glycosylation’ is also seen in red blood cells, and why the HbA1c test which measures glycosylated haemoglobin is so good at predicting our health. If over 6.5% (or 48 mmol/mol) of these erythrocytes are sugar damaged, it’s a clear basis for a diabetes diagnosis. Just as for the omega-3 index, HbA1c is a reliable long-term measure showing the average sugar spikes over the past three months. You can assume what’s happening in the membranes of red blood cells is also happening to the neuronal membranes in the brain. 

This is why the next brain essential is to measure HbA1c.

If 6.5% is the cut-off for a diabetes diagnosis, the ideal level is actually considerably lower. In what is usually considered to be the ‘normal range’, teenagers with HbA1c above 5.4% show cognitive decline and shrinkage of the hippocampus in the central area of the brain compared to those with lower HbA1c levels (3). “In teenagers with raised, but normal levels of HbA1c, there is clear evidence of the same kind of memory problems, and the same areas of brain shrinkage seen in patients with Alzheimer’s Disease” says Dr Robert Lustig.

Shrinkage of the hippocampus is the hallmark of Alzheimer’s and is used to diagnose the disease. A new study shows that 40-year-old adults with so-called normal glucose levels, but at the higher end of the normal range, have increased their risk of Alzheimer’s by 15%. (4) 

A primary function of sleep is to repair all the neuronal membrane damage that occurs during the day. No sleep, no repair and the brain ages fast. This is mainly why lack of sleep is also a strong risk factor for Alzheimer’s.

Do ketones fill the energy gap?

There’s a growing interest in the role of ketogenic diets and ketone promoting supplements for brain health. Professor Stephen Cunnane, our expert in the new science of ‘keto therapeutics’ has shown that giving C8 oil or supplementing ketones can help to prevent Alzheimer’s, slow down cognitive decline, improve mood and lessen anxiety. His studies showed, in those with mild cognitive impairment, that taking 30g (two tablespoons) of mainly C8 oil, resulted in a 230% increased brain energy production from ketones with no change in energy derived from glucose (5), thus filling the ‘energy gap’ so often experienced by older people or those drifting towards insulin resistance. “Our research shows that the areas of the brain that have trouble using glucose for energy are able to use ketones perfectly well, even in moderately advanced dementia. This may explain why many people later in life who are given a supplement of C8 oil or MCT oil have improvements on a battery of cognitive tests. They often feel it brings their brain power back to life” says Cunnane. 

Many people also report feeling calmer, less anxious and less depressed on ketogenic diets. A new book, Change Your Diet, Change Your Mind, out next month by psychiatrist Dr Georgia Ede digs deep into the growing evidence that a ketogenic diet, or at least one low in carbohydrates, is brain-friendly and helps people out of various mental health disorders. Or you can watch the recent webinar she did with us here.

Antioxidant and polyphenol power

The more biologically active an essential fat is (with DHA at the top), the more prone it is to oxidation.

It is literally this ability of DHA to absorb energy (photons from light) that creates the impulse that passes information from the eye to the brain. It explains the origin of the brain and nervous system, going back a billion years to a rudimentary single cell called dynoflagellate. This little organism basically used the electric shock from photons to create the first ‘twitch’ towards light. Where there was light, there was food, and ultimately the evolution of the nervous system and brain. In simple terms, we can see that the brain is really an extension of the eye. How do we see with such precision and speed? Until now, no-one has been able to explain this satisfactorily. At the age of 93, Professor Michael Crawford, who helped our charity get started, has worked out how this occurs and how we see in colour. It requires knowledge of quantum physics, explained in a recent paper entitled ‘Docosahexaenoic Acid Explains the Unexplained in Visual Transduction’.(6)

With all this volatile fatty acid and mitochondrial energy production, cleaning up the oxidant exhaust fumes is a vital function for a healthy brain. So how do we achieve protection and how do we measure it?

There are hundreds, if not thousands of antioxidants and polyphenols in our food. Foods can be measured for their ‘Total Antioxidant Capacity’ or TAC for short. It’s worked out from an equation involving eight key antioxidants from vitamin A, carotenes (think carrots), lycopenes (rich in tomatoes), lutein and zeaxanthine (rich in green vegetables), vitamin E (in nuts and seeds), but most of all vitamin C (rich in berries, broccoli, peppers and other vegetables).

Vitamin C is a keystone nutrient as far as swinging the antioxidant equation in our favour. Individually, the impact of these nutrients on our health may be less than when combined. For example, a study of 4,740 Cache County Utah elderly residents found that those supplementing both vitamin E and C cut their risk of developing Alzheimer’s by two thirds (66%). Taking just one cut the risk by a mere quarter (25%).  (7)

The higher the TAC score of our diet, the lower our risk of memory decline becomes. This was the finding of a recent study of 2,716 people over age 60. Higher TAC scores correlated with better memory function (8). Those in the highest quarter of TAC scores had half the risk of decreasing memory. Powerful stuff!

Tea, cacao, red wine, red onions, olives and berries are rich sources of polyphenols. Many of these polyphenol-rich foods improve circulation, lower blood pressure and dampen down inflammation which lies behind many brain and heart health problems. 

More than a decade ago research in Norway (9) found that the more tea you drink the better; a small glass of wine (125ml) a day (preferably red, as it is rich in resveratrol) reduces the risk of cognitive decline. Cacao is also beneficial, ideally no more than 10g, (about 3 pieces) of dark, 70 percent or more. Other studies based on adding cacao to the diet have shown improved cognition, possibly by improving circulation. This was recently confirmed in a big ‘COSMOS’ trial involving over 20,000 people given a cacao extract supplement versus a placebo for five years (10). The reduction in cardiovascular risk was even greater than that of a Mediterranean diet.

The take-away message? Polyphenols are a vital part of a healthy diet for both our heart and our brain.

So, what do we need to eat and drink to protect our brain and body? Basically, eat a Mediterranean-style ‘rainbow coloured’ diet. A Mediterranean diet has more fish, less meat and dairy, more olive oil, fruit and vegetables including tomatoes, legumes (beans and lentils), and whole grain cereals than a standard Western diet. It also includes small quantities of red wine. There are variations of this kind of diet, called the MIND diet and the DASH diet, but the core components are the same. As researchers drill down, we are learning what to eat and drink and how much, to keep our minds sharp and brain young.

The trick is to really start thinking of the colours we are eating and gravitate to the strong colours, choosing organic where possible. Mustard and turmeric, for example, are strong yellows. Bright oranges include butternut squash, sweet potato, carrots. For red, think tomatoes and watermelons. Anything purple, magenta or blue is brilliant for us too. From beetroots (eat them raw, grated into salads) to blueberries, blackberries to raspberries, all these foods are fantastically good for us, so tuck in!

In addition to food, as a health aspiring 65-year-old, I both supplement 1 gram of vitamin C twice a day and take an AGE Antioxidant containing Co-Q10, alpha lipoic acid, n-acetyl cysteine (NAC – as a precursor to glutathione which is the master antioxidant) and resveratrol as well as vitamin E and A – both beta-carotene and retinol. Many people think that there is no point supplementing glutathione because it is so rapidly oxidised, or sacrificed, to disarm oxidants, but it is also rapidly recycled by anthocyanidins in blue/red berries. So, combining the two reloads glutathione. This film shows how.

But how do we measure our antioxidant status?

My research team is working on exactly this challenge and we are finding that the ratio between reduced glutathione (GSH) and oxidised glutathione (GSSG) in red blood cells is probably the best biological determinant. We hope to introduce that into our panel of functional indicators, and research how it correlates with dietary intake and lifestyle habits as well as cognitive function.

We are due to launch a DRIfT Test as part of a global prevention initiative, which will be a 4 in 1 test

The UK Biobank has collected data on 500,000 people since 2006, inviting people to fill in questionnaires, give blood and carry out certain tests. We are funded by ‘Friends’ who pay £50/$60/€60 a year.  So far we have collected data on 410,000 people and this number is growing by about a hundred a day. 

In addition to taking the blood test, participants are invited to complete a validated online Cognitive Function Test (not a questionnaire), followed by a comprehensive 144 question Dementia Risk Index diet and lifestyle questionnaire which takes 20-25 minutes. This works out a person’s future risk and shows what’s driving the risk. This is a free service.

We run the UK’s leading dementia prevention charity which is running the prevention project together with Dr Tommy Wood, Assistant Professor at the University of Washington. “By tracking a person’s blood sugar, vitamin B, D and omega-3 status against changes in cognitive function over time, in addition to lifestyle factors such as sleep and physical activity, we can learn what really helps prevent cognitive decline.” says Dr Wood, the principal investigator for the study. 

Citizen Science

All donations are put back into research, and the results of the research are shared back to the people. 

This is science for the people, funded by the people, shared back with the people. We call them Citizen Scientists and we hope to reach a million people around the world within a year or so making this the biggest prevention-focussed study of its kind. The purpose of research is to help people. Too often great scientists do great studies, which get published and ignored. We have to face the fact that, in the UK as an example, the Government has commissioned four reports on mental health and Wellcome did a further independent report, all showing we have a cerebral tsunami with brain and mental health disorders ahead of every other disease.

They have ignored every single one.

Change is not going to come from the Government or the NHS. It is going to have to come from us, the people. I urge everyone in natural medicine to take the test themselves, share it with others and support us by becoming Friends and donating £50 a year, getting so much in return.

This is how we are funding our amazing research team. We are a lean, keen, small but mighty team. 

Every donation, big or small, goes right back into helping people prevent these preventable and terrible diseases such as dementia. 

Together, we can change the world. 

We need to because time is running out. 

We will lose our humanity if we don’t stop this brain drain.
