Processed Food & Brain Health: What’s on Your Plate Matters!
In New Zealand, a report found that 69% of the 13,000+ packaged foods surveyed were categorized as ultra-processed. In the United States, 60% of packaged food sold is considered ultra-processed! (PMC34647997) These highly processed foods dominate modern diets, but at what cost to our health—especially our brain health. Could it be that highly processed foods mess with our gut health, and that the health of our gut is DIRECTLY linked to mental health?
the gut-brain connection
Could it be that highly processed foods mess with our gut health, and that the health of our gut is directly linked to mental well-being? Research increasingly suggests that what we eat has profound effects on our brain function and emotional state. A diet rich in whole, nutrient-dense foods supports gut microbiome balance, which in turn influences neurotransmitter production and mood regulation.
the western diet and cognitive decline
A typical Western diet, high in ultra-processed foods, has been linked to cognitive decline and mental health issues such as depression and anxiety. A recent study found that people who consumed the most ultra-processed foods experienced a 28% faster rate of cognitive decline compared to those who ate the least. This alarming statistic underscores the urgent need to re-evaluate our food choices.
real food for better mental health
We don’t need to wait for more research or for scientists to 'piece together' the full mechanism behind these effects—there is already enough evidence showing that real, whole foods positively influence mental health. Nutrient-dense, unprocessed foods provide essential vitamins, minerals, and healthy fats that support brain function, emotional stability, and overall well-being.
more than just weight: food and mood
It’s easy to associate diet with weight management, but what we eat affects more than just our waistline. The food we put in our mouths has a profound impact on our mood, energy levels, and cognitive function. Choosing whole, unprocessed foods over ultra-processed options is a powerful step towards better mental and physical health.
final thoughts
The evidence is clear: ultra-processed foods contribute to gut imbalance, cognitive decline, and mental health issues, while whole foods nourish both body and mind. Prioritising real food isn’t just about weight—it’s about protecting our brain health and emotional well-being for the long run. Let’s make mindful choices and fuel our bodies with what truly supports us!
