How your diet is affecting your mood (Food for Mood series #1)

Life can be busy. Between juggling work, family commitments, life admin, to social events, it’s no wonder we sometimes feel overwhelmed, tired, or even a bit moody.

But did you know that what you eat could be playing a significant role in how you feel, your energy levels and overall mood?

Being a goof, as per usual. Lake District, England.

Diet is one of the most important indicators of overall health, and this extends far beyond just physical well-being.

The food you consume is the fuel for your body, including your brain and Endocrine system; the series of organs involved in hormone production, regulation and balance.

A balanced, nutrient-rich diet not only keeps you physically strong but also impacts your energy levels, stress resilience, and your emotional stability.

Let's talk about the brain-gut connection.

Your gut is often referred to as your 'second brain' because it contains millions upon billions of neurons, which communicate with your brain through the vagus nerve.

This connection is responsible for the production and regulation of neurotransmitters—chemicals including Serotonin and Dopamine that are key players in mood regulation.

Hormonal balancing benefits

For women, diet is especially influential due to hormonal fluctuations throughout the month.

The hormones Oestrogen and Progesterone not only affect physical health but also interact with your neurotransmitters, influencing mood, sleep and energy levels.

Certain foods can support hormone balance, while others may exacerbate mood swings or fatigue.

So, how does diet affect your mood?

When your diet is rich in whole foods—think fruits, vegetables, lean proteins, and healthy (unsaturated) fats—it supports gut health, keeps hormone levels in check and ensures a steady supply of nutrients that your brain and gut needs to function optimally.

On the other hand, a diet high in processed foods, sugar, and unhealthy (saturated) fats can disrupt gut health, leading to inflammation, hormonal imbalances and those mood swings or chronic stress.

Eat the Rainbow. The more colours in your diet, increases the variety of nutrients you consume.

In short, paying attention to your diet is not just about maintaining a healthy weight—it’s about nurturing your mental and emotional well-being.

By making mindful food choices, you can better manage stress, stabilise your mood and boost your overall energy levels, making it easier to navigate the challenges of a busy life with a clearer mind and a happier heart.
