Understanding the Connection: Food and Mood

The first thing you need to understand is that there is a unbreakable connection between our food and mood. You see, when I first started my journey to a healthier life, I was much more concerned with how my meals would affect my physical wellbeing. Sure, we're all familiar with the whole concept of "you are what you eat". And if, like me, you have a darling golden retriever like Honey at home who loves her dog biscuits more than any rabbit, you probably know how a healthy diet boosts their energy and makes their coat shine brighter than a Christmas star.

However, it wasn't until a bit further into my fitness journey that I discovered the massive impact food has on our mental health. It amazed me how the value of a diet extends beyond the physical and delves deep into our emotional and mental state. Suddenly, my entire perspective shifted. It was like turning on a new layer of understanding on my food—each vegetable, fibre, carbohydrates, and protein-rich food had a direct connection to my mood and mental health. I began looking at my plate somewhat differently, seeing not just a meal but an arsenal for my mental strength! Now, I'm not a psychologist, but I understand that my mood does beeline right to my brain. So, essentially, what I eat also affects my brain—it's like, food and mood have a tag team pact against me!

Decoding the Brain-Diet Relationship

Now the big question is, how does this brain-diet relationship work? Well, it all comes down to the pesky chemicals, neurotransmitters, that our brain produces. The food that we eat influences the production of these neurotransmitters, and these are associated with feelings of well-being and happiness. For example, serotonin, which is primarily responsible for regulating mood, sleep and our appetite, is majorly influenced by our diet. Around 90% of serotonin is produced in our gut, so food hugely impacts its production. Fascinating, isn't it?

Furthermore, nutrients involved in brain health include vitamins B1, B9, B12, D, E and Omega 3 fatty acids. These nutrients help in the prevention of brain diseases and mental disorders. Few examples of foods rich in these nutrients are dark leafy greens, lentils, nuts and fatty fish. Hope you've got your shopping list at hand, because these go-to ingredients are a must-have for nurturing your brain! A brain-healthy diet is not about strict limitations, staying unrealistically thin, or depriving yourself of the foods you love. Trust me, I’ve tried it, and it’s the quickest path to a bad day.

Choosing Foods that Foster Positive Mood

When it comes to choosing food that actually boosts your mood, the best advice I can offer is this: think colourful! Like a rainbow that soothes your eyes after a heavy rain, a colourful platter of fruits, vegetables, lean proteins and whole grains can do wonders for your mind. Such a diet ensures you get a wide range of nutrition and sustains a feeling of fullness for longer periods. It's like equipping your body and mind with an all-inclusive shield.

Oh, and about those comfort foods that we often crave during a season finale or a minor heartbreak—you might want to rethink this relationship. Foods high in sugar and bad fats can give a quick boost, but it is often followed by a crash, leading you to a cycle of ups and downs, and not to mention weight gain. It was a heartbreaking, chocolate-stained revelation for me too! Just remember that moderation is key. A bar of chocolate won't destroy your mental health, but a diet overly dependent on processed and sugary foods will.

Role of Hydration and Exercise in Mental Health

Let's not forget about hydration. A well-hydrated body leads to a well-hydrated brain, and this result in better cognitive function and mood improvement. You see, our brain is approximately 75% water, so hydrating regularly gives it the best environment to function optimally. It's like your brain's premium fuel.

But addressing nutrition and hydration alone isn’t enough. Exercise also plays a significant role in enhancing mental health. Regular exercise can have a profound positive impact on depression, anxiety, ADHD, and more. It also relieves stress, improves learning, helps you sleep better, and boosts overall mood. It's like slicing and dicing your stress away with every sweat-soaked workout!

Adjusting to a Healthy Diet

You might be thinking - 'That sounds like a lot of change, Elaina!' Well, who said change has to be immediate? Adjusting to a healthy diet is not a transformation that happens overnight. Believe me, I know. When I first started introducing more greens and fewer sweets into my lifestyle, it was a real battleground. There were cravings, questionable salad dressings, and few mystifying spirulina smoothies. But with each step, I was getting stronger—not just physically, but mentally too.


So, if you've been feeling a little low lately or just in need of a mood lift, try to pay heed to what's on your plate. A healthy diet is more than about cutting calories—it's key to our mental wellbeing too. Remember, a well-nourished body houses a well-nourished mind. With that, I hope this article gives you a fresh perspective on diet and mental health, just as I experienced some years back. After all, mind matters and so does the food!
