Doctors believe that our brains consume roughly 300 calories in the day and the same again at night
COVID-19 has hugely taken its toll on our mental wellbeing this year. From health worries to the stress of home schooling, worry for family and friends to financial difficulties, most people have run the gamut of emotions over the last 6 months. And for many, it is more serious than that – according to the World Health Organisation, who have conducted a study of the mental health of 130 countries, the pandemic has highlighted the devastating effect that COVID-19 has had on our mental health and also underscored the urgent need for medical funding.
And just when we got excited at the thought of throwing off our face masks and returning to life as ‘normal’ most of us are now in a state of limbo, wondering if we will go back into lockdown, or ever return to our old lives at all.
Here at 35thousand, in order to help raise your happiness levels, we have decided to do a series of articles that will delve into the various different areas of ‘mood-boosting’. Starting here with the benefits of eating nutritious food, we will also look into psychological, physical and therapeutic ways of lifting our spirits in articles to come.
In recent years , we have become far more aware of the link between the state of our gut and our minds. Scientists have now proven that our gut is responsible for producing a large proportion of our neurotransmitters, the chemicals that transmit information throughout the body and brain. In fact, it has been shown that as much as 90 per cent of serotonin (our so-called ‘happy’ hormone) is made in our gut, so it goes without saying that if the state of our stomach is out of whack, then our brains could well be too.
Not only that but scientists have shown that it’s not just our bodies that require fuel – brains get hungry too. Doctors believe that they use up about a quarter of our daily energy supply, consuming roughly 300 calories in the day and the same again at night. It is therefore vitally important says dietician Rachel Clarkson that we support the link between the gut and the brain (the gut/brain axis) by fuelling ourselves with optimum foods which may well help keep anxiety, depression and other mental health disorders at bay.
But it’s no good throwing a packet of probiotics into your supermarket trolley and hoping for the best. According to Rachel when it comes to the gut/brain axis there should be a multi-pronged approach. She suggests the following…
We want to make sure that we have adequate levels of serotonin in our bodies explains Rachel, “This chemical messenger contributes to happiness and wellbeing, but in order for it to be produced it required the amino acid tryptophan to be present, which you can get through your diet by eating tryptophan-high food.”
Rachel therefore suggests eating tofu, egg yoke, salmon, turkey, and plenty of nuts and seeds. She adds, however, that it is important to know that tryptophan is enhanced when eaten with a carbohydrate (which is why, perhaps, she thinks we have sugar cravings). She therefore suggests pairing the above with, say, brown rice, quinoa, lentils or fruit. “You could have eggs on toast for example or a tofu stir-fry or maybe a turkey and cheese brown bread sandwich,” she says.
Our gut microbiome has been the health buzzwords of the last few years, but for good reason – this flora of different bacteria lining our intestines has been proven to be hugely beneficial for our health if looked after correctly. “We want to support a vast microbiome as poor microbiome variety has been linked to stress, depression and anxiety,” says Rachel. “The gut brain axis is the interaction between the microbiome in your gut and the cognitive and emotional centres in the brain.”
What is key, she explains is that we all have a diverse range of good bacteria in our stomachs which will involve eating a diverse range of plant foods. In particular, she also suggests eating fermented foods or live cultures which will add beneficial bacteria and enzymes into your overall intestinal flora. She therefore suggests adding Miso, Kimchee, Kombucha, Sauerkraut, and yoghurt into your diet where you can. When it comes to yoghurt, however, look out for the words ‘active’ or ‘live’ on the label or mentions specific good bacteria.
You also, she explains, want to feed the Microbiome with prebiotics (this is the food that the bacteria feed on) ,and this involves eating a lot of fibrous foods where you can. Some suggestions would be beans, leeks, onions, artichokes and whole wheat bread or pasta.
As for probiotics, Rachel suggests that unless you have a diagnosed digestive/health issue, then it’s best to opt for naturally occurring probiotics in fermented foods.
We all know what it’s like to feel ‘hangry’ when we are haven’t eaten, and how this can make us feel low or jittery, and anxious. What we don’t want, explains Rachel, is for our body to go into hypoglycemic mode, where our blood sugar is too low. She therefore suggests eating a healthy portion of whole grain carbs at most meals in order to maintain a steady flow of glucose. This she says, “Can be in the form of fruit, or quinoa, buckwheat, chickpeas, sweet potatoes and it’s important to eat wholegrain bread and pasta where you can.”
If you are suffering from low mood, Rachel suggests potentially steering clear of low carbohydrate diets which have been particularly popular I recent years. “Low mood can be associated with nutrient deficiencies such as B vitamins and selenium which are found in foods such as bread, lentils, cereal, milk and bananas, so a low carb diet may exacerbate these further,” she says.
It may sound boring and you are probably sick to death of hearing the word ‘balance’ from health professionals, but if you don’t have a diet that contains carbohydrates, proteins and healthy fats, then you may be lacking in nutrients that are associated with mood. For example, if you are either low in iron or lacking in B vitamins you may feel low and irritable.
It’s incredibly hard to prescribe one eating plan for everybody as our bodies and goals are all so different but as a general rule, (and especially is you are susceptible to low mood), Rachel suggests including a wholegrain carbohydrate at breakfast, at lunch and a as snack, but keeping it optional for dinner. She also suggests eating protein at every meal and incuding a healthy fat too.
There is evidence around the benefit of Omega3 supplementation for people with diagnosed clinical depression says Rachel.
Note: these should not to replace any medication.
Your brain can’t function unless you are well hydrated so you may feel fatigued if you don’t hydrate throughout the day. Aim to drink 6 glasses of water a day.
Rachel also highlights the importance of managing our emotions around eating, “It’s important to try to take away any feelings of guilt,” says Rachel, “So we feel happy and healthy in our minds instead of feeling shameful. If you do eat something indulgent then take a breath and acknowledge that you have enjoyed that food and then put it behind you move onto the next healthy meal.”
Rachel Kelly is the author of The Happy Kitchen and The Happiness Diet. Having suffered from anxiety and depression for many years, it wasn’t until she researched and improved her diet that she realised how good much better she felt. Created with nutritional therapist Alice Mackintosh, they consist of gut and brain-boosting recipes for breakfast, lunch and dinner.
Here’s a sample recipe from The Happy Kitchen
Alice says ‘I have this for breakfast if I wake feeling whacked. Alice designed it so that I could get lots of energy-boosting goodness in one go. These fruits are rich in vitamin C and fibre, while the walnuts an avocado deliver protein and healthy fats to balance everything out. The oats and nuts add substance and slow down the absorption of sugar from the fruit and the cinnamon may also reduce sugar cravings.”
½ papaya and 1 whole mango
1 tbs oats
250 ml almond, coconut or oat milk
Cinnamon to taste
Peel the papaya or mango and remove its seed or stone
Chop it into medium-sized shunks and pop it into a blender with all the other ingredients. Blend until smooth
