The Brain on Ketones; Following a Ketogenic Diet to Improve Brain Health

The Brain on Ketones; Following a Ketogenic Diet to Improve Brain Health

From Low GL to Ketogenic 

At Food for the Brain, one of the key messages we enforce is the importance of eating a diet that’s low in glycemic load, which in other words means avoiding refined sugars and flours, and swapping them for wholegrains, fibre-rich legumes and starchy vegetables. These sources of carbohydrates release their sugars gradually instead of all at once, which not only helps to sustain energy levels throughout the day, but also positively impacts the brain, which is sensitive to fluctuating blood sugar levels. Research in the last 10 years has exploded on the role that insulin resistance and insulin deficiency (caused by diets high in refined sugars) plays in cognitive decline and the development of Alzheimer’s disease, so much so that scientists have begun to label Alzheimer’s as a type 3 diabetes or diabetes of the brain. Switching to a low GL diet is relatively easy, but what about those diets that go as far to say that eliminating carbohydrates almost completely from the diet, such as in the ketogenic approach, is more efficient in improving brain health?

What is the Ketogenic Diet? 

The ketogenic diet was first introduced by physicians in the 1920s for the treatment of childhood epilepsy, after scientists discovered that during periods of fasting the body begins to use fat as a source of energy instead of glucose, which resulted in less seizures in patients. Two specific compounds were found to be produced in the body during fasts – acetone and beta‐hydroxybutyric acid – now known as ketones, which are a byproduct of fat breakdown in the liver and are used by the body as energy when there is no more glucose available. During this research study, scientists discovered that following a diet with moderate protein, minimal carbohydrate and high fat (roughly 60%-80% fat,15%-35% protein, 5% or less carbohydrates of total daily caloric intake) could also lead to the production of ‘ketosis’, where the body begins to use ketones as energy instead of glucose. Improvements in behaviour and cognition were also reported, which set the tone for future trialling of the ketogenic diet to improve brain health for a variety of conditions.

Why is ketosis good for the brain? 

Research on the ketogenic diet in the past few years has increased, in particular its therapeutic application in symptoms related to neurological disorders and mental health, as well as in treating conditions such as type 2 diabetes. Whilst the exact mechanism of how ketones improve brain health is still unclear, ketones used as fuel for the body have shown to increase neuronal growth factors (meaning neurons are able to regenerate and proliferate), reduce brain inflammation and oxidative stress, strengthen signals between synapses and enhance mitochondrial respiration (a process of energy production that takes place in our cells). 

Human studies are, however, minimal in researching the value of the ketogenic diet in improving brain health, with most scientific studies still being focussed on animals. In addition, many studies use supplements such as MCT (medium-chain triglycerides) capsules to induce the production of ketones in the body, which may be due to the fact that following a ketogenic diet and monitoring large groups of people is difficult. MCTs are fatty acids that do not require bile to be digested, instead they go directly into the liver and are able to feed into the mitochondria of the cells without needing L-carnitine to shuttle them across the mitochondrial membrane, unlike other fatty acids. This translates as an immediate energy source, functioning much like simple carbohydrates do but without the impact on blood sugar levels.

There has been some positive results using supplements such as MCT. For example, in a 90-day randomized, double-blind, placebo-controlled, parallel study of 152 people with mild to moderate Alzheimer’s Disease, a daily MCT supplement was given. Participants were asked to take a cognitive test at 45 and 90 days using the ADAS-Cog scale and patients taking the MCT supplements showed significant improvement in the cognitive test, unless they carried a gene called ApoE4, which is associated with a higher risk for developing Alzheimer’s disease.

Can the ketogenic diet help with mental health symptoms? 

The majority of studies are animal-based, which despite demonstrating positive results, there is still a long way to go with regards to understanding the direct mechanism of how the ketogenic approach alters brain chemistry and its value in long term improvements to mental health. One interesting study in children with medication resistant epilepsy, showed how following the diet had a significant impact on the neurotransmitters, dopamine and serotonin, both of which are implicated in depression and anxiety. The children followed the diet for a period of 3 months, neurotransmitters were measured before and after in their CSF (cerebrospinal fluid). Metabolites of both serotonin and dopamine had significantly reduced after following the ketogenic diet, demonstrating that these neurotransmitters were being utilised more efficiently in the brain.

There have also been some case studies that encourage further research into this field. In one particular study, a significant improvement in symptoms were reported. 2 women with bipolar disorder type II followed the ketogenic diet for an extended period of 2 and 3 years respectively. Only one measured their macronutrient composition, which was roughly 70% fat, 22% protein, and 8% carbohydrates, and ketones were measured in the urine. Both women reported subjective improvement in mood stabilisation as well as an overall improvement of their condition, which surpassed the effects of medication.

Is it safe to follow the ketogenic diet unsupervised? 

Research to date suggests that the ketogenic diet is safe for most people, however, it has a large impact on the body and for this reason we would always advise people to seek expert guidance before trying it, especially if they are are on medication of any form. According to Dr Georgia Ede, a Harvard-trained psychiatrist and nutrition consultant, in the first couple of months of the ketogenic diet your body goes through profound shifts in chemistry, which may affect the metabolism of medication, as well as significant mood changes. Here is a list of medications related to common mental health conditions and how they can be affected by following the ketogenic diet.

Whilst the emphasis is on achieving the correct amount of macronutrients (ratio between carbohydrates, protein and fat) to encourage ketosis, the nutrient value of food should also be taken into account in order to prevent deficiencies. For example, many may be drawn away from having a significant amount of vegetables on the keto diet,  due to the fact that some can be high in carbohydrate content. However, it is critical to ensure enough fresh vegetables whilst undertaking this approach to prevent falling short on micronutrients that play an important role in our cellular health and preventing oxidative stress. In addition, eating the right protein and fat sources is also very important, as processed meat and hydrogenated or refined oils can leave us more vulnerable to long-term health problems such as cardiovascular disease.

Low GL or Keto?…

Whilst research on the ketogenic diet and brain health has showed and continues to show some positive results, it’s still very much in the early stages and a lot needs to be understood about the underlying mechanism of how ketones improve biomarkers associated to poor mental health and the long term impacts of this dietary approach. Eating a diet that’s low in glycemic load may be an easier, more accessible way of switching to a way of eating that has little impact on blood sugar levels and encourages a healthy insulin response, which has shown to have a positive impact on cognitive health.

Where to go for support…

We believe that following a ketogenic approach should be under the guidance of a nutrition professional, to ensure you’re still getting the right nutrients and that the diet is tailored to your individual needs. If you’d like to reach out to a qualified nutritional therapist to guide you through this process, BANT (British Association for Nutrition and Lifestyle Medicine), have a search engine for practitioners that are local to you. Our not-for-profit clinic, the Brain Bio Centre also have a team of therapists that specialise in brain health and can discuss the best approach for you individually.

Nutrition Tips to Support Children with ADHD

Nutrition Tips to Support Children with ADHD

Nutrition; the Building Blocks of Health

Proper nutrition is important for all children to help them grow and develop, both physically and mentally. It stands to reason that the brain benefits from the best possible nutrition as much as the body, and the evidence-base in this area is growing. Many vitamins and minerals support brain health including magnesium, zinc, B vitamins, calcium and iron, some of which are often found to be low in tests.

Key Nutrients for Brain Health

Magnesium, in particular, supports improved focus and concentration, and supports calm and sleep. Vitamin D is a key brain nutrient and deficiency is very common in the UK. Most children would benefit from vitamin D supplementation especially those with learning, behavioural or developmental differences. Colourful plant-based foods contain a range of special nutrients known as phytonutrients which also support brain health. Omega-3 essential fats have a very important role in optimising brain function. Blood tests reveal that most children with learning, behavioural or developmental differences have low or sub-optimal levels of these important fats. These fats are found in oily fish and fish oil supplements. Specific amino acids from protein-rich foods are involved in neurotransmitter production which can have a range of effects including balanced mood, better concentration, reduced anxiety and improved sleep.

Sugar; the Brain’s Enemy

Sugar is, quite simply, bad for the brain. Most children, including those on quite ordinary diets, take in excessive sugar and refined carbohydrates which adversely affect their health including behaviour, concentration and sleep. Many sources of sugar are ‘hidden’ in foods which are marketed as ‘healthy’ or ‘low fat’, making this a minefield for parents. In fact, fat is an essential nutrient for the growing child’s brain.

The Gut Brain

Food sensitivities may contribute to symptoms too. It is best to work with a nutritional therapist to identify which foods or food additives are affecting your child before making major changes or cutting out whole food groups. The bacteria in your child’s gut (‘gut flora’) can have a significant impact on brain function too. Assessing the mix of gut flora and improving the balance can affect learning, behaviour, mood, development and supports physical health and immunity. Gut flora balance is heavily influenced by diet (the bacteria live off the food that your child eats), so whilst probiotic (good bacteria) supplementation can be very helpful, it is dietary change which is required over the long term.

The Importance of Working with a Nutritional Therapist

Nutritional therapy works well alongside other therapies including medication and other therapies, and these therapies may be even more effective in a well-nourished individual. Even children who already eat a relatively healthy diet are likely to benefit from nutritional therapy. The benefits that most parents report including better focus and concentration and improved sleep, along with reduced sugar cravings, fewer coughs and colds, and a healthier digestive system (fewer tummy aches, constipation, bloating etc).

Nutritional support for depression before, during and after pregnancy

Nutritional support for depression before, during and after pregnancy

According to Dr Vivette Glover, Director of the Foetal and Neonatal Stress and Research Centre, at any one time during pregnancy, one in every ten women will be depressed and around one in every thirty will be depressed both during pregnancy and the postnatal period (1). It is not yet understood exactly what causes the symptoms associated to depression during and after pregnancy. However, factors such as the large changes that the body undergoes due to the demands of the growing foetus, as well as breastfeeding and potential sleep deprivation, can all play a significant role in how the body deals with stress. It is during this period of time that our bodies require more nourishment from food than ever and it can also be at exactly this time when we perhaps struggle to prioritise nutrition due to lack of energy, loss of appetite or sickness.

Pre and Post-Natal Depression are both complex conditions that can have multifactorial underlying drivers, including genetic and environmental influences. These are currently poorly investigated and the gold standard of treatment is often medication to help stabilise mood. Whilst SSRIs and other types of antidepressants have proven to be helpful for many, they do not address potential causes or drivers of poor mental health and can often mask symptoms. Antidepressants are also not regularly recommended during pregnancy, which is why being more mindful of nutrition and lifestyle habits can be a safer option for you and your baby. There are some natural, evidence-based steps you can take to help support optimal mental wellbeing:

Eat Foods to Support Energy Depletion:

Common issues such as poor sleep during pregnancy and sleep deprivation following the birth can often heighten cravings for stimulants and sugary foods, which may seem like a good option for quick sources of energy, however, these foods can often cause further issues with energy and lead to fatigue and low mood. Eating foods that are high in refined sugar and refined grains such as commercial white bread, pastries, cakes and biscuits, give us an unsustainable source of energy. The brain is a very metabolically active organ; despite it only being 7% of the body’s weight, it can take up to 20% of the body’s metabolic needs (2), meaning that it is very energy hungry. This is why it is important to nourish the brain with foods that are nutrient rich, providing the body the building blocks to produce neurotransmitters, as well as a sustainable source of energy. The best options are fresh, unprocessed foods such as wholegrains (brown bread, brown rice, quinoa, rye and oats), pulses, vegetables, good quality sources of protein (meat, poultry and fish) and healthy fats such as those found in olive oil, coconut oil, avocados and oily fish.

Just like throughout pregnancy, nutritional needs after birth, especially if breastfeeding, are incredibly important. The healthier the diet, the easier it will be to sustain the energy needed to take care of a newborn. Research shows that a breastfeeding mother needs an extra 300-500 calories a day, from food that is rich in the right macro and micronutrients to nourish both mother and baby (3). For example, nutrients such as B vitamins have shown to be important in supporting the mother in ensuring she has enough energy to meet the demands of lactation (4). These nutrients can be found in green leafy vegetables, wholegrains and good sources of animal protein.

Protect yourself from Oxidative Stress:

Oxidative stress refers to a biochemical process that occurs as a result of an accumulative everyday exposure to toxic burdens such as chemicals in cosmetics, furniture, paints, cars, and pollution. Our body has its own way of armouring itself from the damage that exposure to toxins can create through its production of endogenous antioxidants, which is nature’s way of neutralising oxidative stress. Although we have our own production of these wonder molecules, when we are continuously overloaded with toxins in our environment and have problems detoxifying, the liver can become overwhelmed. Research shows that over time oxidative stress can lead to an increase in inflammatory molecules such as cytokines, which have been shown to correlate with depression (5).This is why it is important to have a high intake of nutrients that support the liver in metabolising and removing toxins from the body, as well as regulating the inflammatory response. There are a few things we can change in our diet to support this area, for example eating foods such as the cruciferous family of vegetables which includes kale, cauliflower, broccoli and cabbage. These are particularly effective at supporting the liver in ushering out toxins as they all share an antioxidant compound called indole-3 Carbinol, which plays an important role in liver health (6). In addition, bitter greens such as collard greens, rocket, chicory and swiss chard are also great for supporting the liver’s own antioxidant defence system.

Increase intake of Omega-3 Fatty Acids:

During pregnancy and after pregnancy there is often a concern for the potential depletion of the maternal nutrient reservoir due to the needs of the growing foetus. A nutrient that is particularly important for mental wellbeing and is also essential for the growth of the foetus’s brain, is DHA. This is an omega 3 fatty acid that is found in oily fish and is the primary structural component of brain tissue, as well as playing a crucial role in the maintenance of brain cells and neurotransmitter metabolism (our body can also convert plant sources of omegas 3’s into DHA, such as those found in flaxseeds or chia seeds into DHA, but the conversion can often very poor). Deficiency in this nutrient during pregnancy is common, namely because of lack of seafood intake (the most bioavailable source of DHA) due to poor eating habits and concerns of mercury levels in fish during pregnancy, as well as higher requirements during foetal growth, which can lead to depletion. Due to the role that DHA plays in neurotransmitter metabolism, deficiency in this nutrient has been correlated to symptoms of depression during pregnancy (7). In order, to support your intake of omega 3, aim to have 3 portions of oily fish a week from sources that are low in mercury. These are mainly small fish that have a short life-span such as sardines, mackerel and herring. If you are vegetarian or vegan, although omega 3 is less readily available, it is still possible to get this nutrient from your diet through flax seeds, chia seeds, walnuts and seaweed. If you feel you may not be getting enough through your diet, you may want to consider using a good quality fish oil supplement (or algae based supplement if vegan) as an option. With fish oils, aim to choose a supplement that has been filtered for heavy metals and other pollutants to make sure you’re getting the full benefits of the omega 3 oils.

Exercise and Personalised Nutritional Therapy:

In addition to diet, there are many other things you can also do related to lifestyle, such as stress management through mindfulness (8) or gentle movement such as pre or post natal yoga (9), which have both shown to be incredibly helpful in encouraging mental wellbeing. If you feel you need extra support, personalised nutritional therapy can be very helpful as there can often be other drivers such as nutrient deficiencies and digestive complaints that can play a significant role in mental health and will need to be addressed in a way that is tailored to the individual.

What is the Biochemical Approach to Autism?

What is the Biochemical Approach to Autism?

Autism is a complex neurobiological disorder that is usually diagnosed in early childhood and typically persists into adulthood. Every child has a unique presentation. Core features include difficulties with social communication and interaction (which can vary significantly in severity), but children frequently have other (co-morbid) conditions, such as digestive and sleep issues, which are not core features of autism.

The mainstream approach to autism primarily involves specialist educational and behavioural programmes that focus on communication, social interaction, imaginative play, and academic skills.

A complementary approach is known as the biomedical approach. This typically refers to a group of interventions which are designed to stop, or at least reduce, the effect of biomedical problems (such as gastrointestinal abnormalities, immune dysfunctions, detoxification abnormalities, and/or nutritional deficiencies or imbalances). Core biomedical interventions include special diets and nutritional supplements, and many practitioners will use biochemical or functional tests to measure biomarkers in urine or blood.

There is a lot of scepticism about this approach from healthcare and other professionals. For example, they may say that there is no evidence that a special diet will help. The accounts of thousands of parents who have successfully used a biomedical approach does not count as evidence, because within mainstream medicine, the only type of evidence which actually counts as evidence are properly conducted scientific studies which pit one approach against another in a controlled setting (a randomised controlled trial or RCT). It would also be true to say that there is absolutely no evidence that (for example) a special diet doesn’t work – the trials have not been conducted. In autism research there are significant ethical hurdles and funding issues. Medical research is largely funded by commercial pharmaceutical interests with the aim of creating a patentable drug treatment which can be sold for profit (to fund the cost of the research and provide shareholder value). Drug treatments have not been found to be particularly successful in autism, probably due to the homogeneous nature of the condition (there are a multitude of probable causes and each individual is so unique), so there is no real value to the investor in drug research.

If you are considering taking a biomedical approach to autism, then a quick Google search will reveal an absolute mass of information, books, testimonials, videos and products for you to navigate which is quite frankly bewildering. Again, because of the heterogeneous nature of autism, there isn’t a clear pathway to follow. So, where do you start, and whom do you trust? You might read some apparently ‘miracle’ success stories where a parent has used a single intervention, but for the majority of cases, progress is typically slow and steady, halting at times and usually requires a multi-pronged approach. We would always recommend a biomedical approach alongside educational and behavioural programmes.

The first thing to really appreciate is that there is no one-size-fits-all diet that will be right for every child – and therein lies the complication. The most important consideration of course is that no harm comes to the child. And that is why working with an appropriately trained, qualified and experienced practitioner who can work with you and your child to develop an individualised programme is key.

However, there are some things that you can do yourself at home which can only be helpful. Children with ASD are usually very sensitive individuals, and often have food or sensory issues, so the most important piece of advice is to make changes very slowly and gradually, and one at a time.

Reduce or eliminate sugar: begin by cutting out the obvious sugar. Don’t be tempted by alternative sweeteners. Dilute juices gradually until they are water. Reduce the amount of carbohydrate (rice, pasta, bread, potato etc) to be about a quarter of the meal or snack. Reduce the sugar effect of the carbohydrate by increasing the amount of protein, fat and fibre that the meal or snack contains. For example, add olive oil, fish and vegetables to pasta.

Eat unprocessed food: try to move to real food so that you can control the ingredients. For example, make the switch from a store-bought smoothie, by gradually adding increasing amounts of a home-made version. Ice-cube trays of blended fruit, seeds, coconut milk can help with the practicalities of this gradual transition.

Pollution: avoid outdoor and indoor pollution as much as possible. Avoid heavy traffic and busy roads. Keep indoor pollution to a minimum – ditch the deodorisers, fragrant fabric softeners, air fresheners etc. If you need a fragrance in the home, use pure essential oils such as lavender and chamomile.

Support healthy immunity: don’t over-sanitise – some level of exposure to germs helps the normal functioning of the immune system. Many children will benefit from probiotic supplementation, especially if they have had antibiotics.

Gluten and casein-free diets are actively discouraged by the NHS and other authorities as being ineffective and potentially dangerous. However, the vast majority of parents report them to be incredibly effective. Making such dramatic changes to a child’s diet should be done only with the appropriate supervision.

At the Brain Bio Centre, we are passionate about helping parents and carers to support their children (and adults) with autism to have the best possible outcomes and quality of life. Please contact us to find out how we can help you.

Glutathione: the Master Antioxidant and its Role in Brain Health

Glutathione: the Master Antioxidant and its Role in Brain Health

Glutathione has been labelled as the mother of all antioxidants and the ultimate free radical quencher and detoxifier. We produce this molecule endogenously, primarily in the liver, using the precursor amino acids cysteine, glutamine and glycine, which come from the food that we eat. Research shows that as we increase in age our levels of glutathione gradually go down and deficiency of this antioxidant has been associated with Alzheimer’s and depression, as well as other chronic illnesses such as cancer

Glutathione’s role in the body is multifactorial; it helps to regulate and regenerate immune cells, as well as playing a vital role in cellular respiration, detoxification and provides a defence against oxidative stress. It is a coenzyme that plays a role in various enzymatic reactions and is unique in that it contains sulfur chemical groups, which act like traps for harmful free radicals and toxins, essentially sticking to them and carrying them into bile and into the stool to be excreted from the body. When talking about glutathione in relation to the brain, it is important to address that the brain is especially sensitive to oxidative damage. One of the reasons for this is that it requires a large amount of oxygen to function normally, which as a consequence leads to a large production of free radicals, which is why our antioxidant status is vital in mental health and neurological conditions. 

There are many factors that can contribute to a deficiency in glutathione, which diminishes our defences against toxins and oxidative stress. Research shows that poor diets that are high in refined sugars, processed foods, refined vegetable oils, low in antioxidants and essential nutrients, as well as other factors like exposure to pollutants, stress, frequent infections and a high intake of medications, can all negatively impact our glutathione levels. Glutathione is normally recycled and continuously reused in the body, however, when our toxic load becomes heavier than we can manage, this process can become depleted. Some medical professionals suggest that this may be because we have not evolved to function optimally yet in the environment most of us live in today. Our diets, which are unfortunately made up of nutrient-depleted foods, as well as exposure to high levels of pollution and other sources of environmental toxins, prevent the glutathione antioxidant system from working.

In light of the recently published research showing how 5 fruit and veg portions a day may actually not be enough to keep us healthy, it might be worth trying to follow the recommendations of 10-a-day. At Food for the Brain, we endorse a diet that is richer in vegetables over fruit, as well as a healthy intake of essential fatty acids, lean proteins and wholegrains. This is due to research showing how a diet that is low in glycaemic load can help stabilise blood sugar levels and therefore help optimise brain function. Whilst fruit is indeed healthy and offers a wide range of key micronutrients, due its high levels of natural sugars, it is important that this is balanced with other foods such as those from the food groups listed above.

So what can we do to help optimise our glutathione levels? Aside from eating a healthy diet, there is a family of vegetables that have been indicated to be particularly helpful in encouraging optimal levels of glutathione. This is the cruciferous group of vegetables, which contain high levels of sulforaphane, a phytochemical that encourages the production of glutathione. For example, in a study at John Hopkins University, forty boys and young men, ages 13 to 27, with moderate to severe autism, were treated for 18 weeks with a daily dose of either a placebo or sulforaphane, a plant chemical derived from broccoli sprouts. The study found that many of those taking sulforaphane substantially improved in several aspects of their behavior during treatment. Apart from broccoli, other cruciferous vegetables include cabbage, artichoke, kale, cauliflower, brussel sprouts, kohlrabi, pak choy, turnips, watercress and rocket.Other studies have shown how sulforaphane can have antidepressant effects due to its antioxidant, anti-inflammatory and neuroprotective activity. 

In addition, increasing your intake of the mineral selenium is also a key factor in improving glutathione status. It is a structural component of glutathione and a co-factor of the antioxidant enzyme glutathione peroxidase. This mineral is commonly low in the typical Western diet that is deficient in good quality organ meats, seafood and nuts such as Brazil nuts, which are the richest source of selenium. Selenium depletion in farmed soils where our vegetables are grown and animals pasture can also play a factor in this.  Another simple and accessible way of increasing glutathione production is by having a good night’s sleep. Studies have shown how sleep deprivation can increase oxidative stress in the brain and deplete glutathione levels. 

Taking these steps can help you optimise your brain function and optimal health. At Food for the Brain, we are committed to empowering people to take charge of their own mental health through positive dietary and lifestyle recommendations. Increasing research is showing just how important it is to consider nutrition as a key player in our mental wellbeing, which is why our message is so important.

November for Men’s Mental Health

November for Men’s Mental Health

In the past few years, November has been marked by a sudden rise in an unusual amount of men embracing their moustaches as they campaign for men’s health throughout the month. Since 2003, November has been coined ‘Movember’ by the Movember Foundation, originally a campaign that was launched to tackle issues related to prostate cancer and now raising awareness and funds for the biggest issues in men’s health, one of which is mental health and suicide prevention. The statistics related to men’s mental health are alarming and here at Food for the Brain, we feel that it is important to draw some attention to them. According to the latest figures, 3 out of 4 suicides are men and it is the leading cause of death in England and Wales for men aged between 20 and 34 years. This may be of no surprise considering that men are less likely to access psychological therapies than women; only 36% of referrals to IAPT (Increasing Access to Psychological Therapies) are men. In addition, men have measurably lower access to the social support of friends, relatives and community. This indicates that there may be a serious epidemic of men that have not been diagnosed, in comparison to women.

Mental health is tough to talk about. However, many people don’t realise that a diagnosis does not mean you have to live with it for the rest of your life. Recovery is possible. At Food for the Brain, it is our mission to generate awareness about how nutrition and lifestyle changes can make a big difference to mental health. Whilst there may not be obvious biochemical differences between mental health in women and men, statistics show how men are more at risk of suffering from mental health issues caused by addiction to alcohol or drugs, which is an area that diet and nutritional therapy can play a significant role in, supporting recovery and potentially reducing the risk of relapse. Recent figures show that men are nearly three times more likely than women to become alcohol dependent, are three times as likely to report frequent drug use than women and more than two thirds of drug-related deaths occur in men.

Nutritional therapy can be highly effective in supporting mental wellbeing by preventing cravings for substances such as alcohol and illicit drugs through optimising brain health. The brain uses up more energy than any other organ in our body. It consumes about 20% of the body’s energy requirements and therefore requires a consistent supply of fuel. Even when we may not appear to be using it, such as when we’re sleeping, there is still a high baseline consumption of glucose, which is our body’s main source of fuel. Two thirds of the brain’s energy are used to help neurons, our brain cells, send signals, but the remaining third is used for basic housekeeping, or in scientific terms cell-health maintenance. When our brains are healthy, the rest of our body is healthy, plus we also feel great. Those with mental health conditions and/or addictions often have issues with blood glucose dysregulation, meaning the brain is getting an inconsistent supply of energy. According to NICE, depression is the most common psychiatric disorder witnessed in the diabetes community and people with diabetes are 3 times more likely to have depression than those that don’t. This indicates that blood sugar control is important when treating depression and other mental health conditions.

A key way to prevent this is by eating foods that are low in glycemic load, meaning they have little impact on your blood sugar levels. Foods that are high in glycemic load include refined grains such as white bread, pastries, baked goods, white rice, desserts, sweets, chocolates, fizzy drinks, alcohol and fruit juices. These are important to avoid and replace with a diet that is rich in vegetables, whole grains such as wholemeal bread and brown rice, legumes, whole fruits, healthy fats like olive oil, nuts and seeds, and finally good quality protein from eggs, chicken, fish and some red meat, all of which have little impact on our blood sugar levels and provide sustainable sources of energy for the brain and body.

Another key area to look at is increasing intake of Omega 3. This important nutrient is an essential fatty acid that we need to include in our diets as we cannot make it in our body. Omega 3 plays an important role in supporting nerve conductivity in the brain and for regulating inflammation. Depression is now being considered by western medicine as a symptom of chronic and systemic inflammation, so much so that anti-inflammatory drugs commonly used for rheumatoid arthritis are now being used successfully in trials to treat depression. Oily fish such as sardines, mackerel, anchovies and herring are great sources of Omega 3, however, it can also be found in some nuts and seeds such as flaxseeds, walnuts and chia seeds.

Men have different nutritional requirements than women and have a higher metabolic demand.Therefore, it’s important that foods containing empty calories, i.e. those poor in nutritional value, are replaced with healthier alternatives. Making small changes such as swapping foods that are high in sugar, like those listed above, for a diet that gives you more nourishing sources of energy, can be highly effective in stabilising mood and supporting mental wellbeing.
