Nutrition and hydration week - how food can affect your mood

The saying goes that we are what we eat and what better time to look at whether there’s any truth in the saying than during Nutrition and Hydration week?


When it comes to drinking, people often choose alcohol to help change their mood. They may have a tipple to feel more relaxed, to help them engage more freely with others, or to give them that ‘happy’ vibe. However, evidence suggests that while alcohol does indeed change our mood, it’s not in the way we think. As a depressant, booze is likely to worsen symptoms of anxiety. So as we drink to alleviate feelings of stress, sadness or anxiety, in reality alcohol is exacerbating them.

The same can be said of caffeine. When taken in a drink, Caffeine quickly blocks the action of a brain chemical called adenosine. It’s a naturally occurring sedative so without it we feel more alert and sharp. That’s why coffee is a popular morning beverage However, for people pre-disposed to feelings of anxiety, it can actually leave you feeling more anxious.

Similar chemical changes occur in our body when we drink sugary drinks too. We get a rush and peak of energy as the sugar reaches our system – which can feel great and make us more productive – only to crash again soon after as our body over-produces insulin to absorb all the sugar. This leaves us feeling irritable and less able to focus. These highs and lows can be significant when it comes to managing our moods.


There are a number of studies that have been done into the links between what we eat and how it impacts our mood. But the converse is also true – does our mood affect what we choose to eat, and in doing so does it create a vicious circle? We feel down so we make bad food choices that only serve to make us feel worse. This article in psychology week looks at the many ways in which our mood affects our food choices and the impact this then has on our body and brain.

There are a few golden rules to follow if you believe that your food choices could be impacting on your mood. It’s not rocket science, but it’s always best to look at the some of the most common contributory factors before we look at other ways of modifying our eating and drinking behaviours.

Five golden rules to boost your mood

  1. Eat regularly to avoid peaks and troughs in blood sugar – food fuels the body and without it we cannot function properly.
  2. Eat more carbohydrates – carbohydrates help your body produce serotonin which makes you feel ‘happy and healthy’. But make sure they are 'complex' carbohydrates from wholemeal foods rather than carbohydrates from refined foods, which will result in peaks and troughs in blood sugar (see point 1)
  3. Eat plenty of fish to make sure your levels of omega oils are topped up – a deficiency has been linked to low mood.
  4. Eat plenty of iron to keep energy levels up – without iron we can feel fatigued and preoccupied.
  5. Eat less fat – it quite literally weighs us down and leaves us feeling sluggish.

According to mental health charity Mind, improving our diet can lead to greater positivity, more energy, clearer thinking and calmer moods. They outline eight tips on how to improve your mood through food -  – including drinking more water and making healthy choices

Unfortunately, there is no one rule fits all when it comes to ‘clean’ eating and drinking habits that will improve our mood. Our bodies are all different and as such, we will each react differently when we consume certain food and beverages. What we can do, however, is get to know how our bodies react to what we put in our mouths and make more mindful decisions about what we consume in order to keep our spirits high.
