The effects of preservative, water and nutrients on your brain and ability to focus


The effects of preservatives, lack of nutrients, and inadequate water intake can collectively have a notable impact on brain function.


Preservatives are chemicals added to food products to extend their shelf life and prevent spoilage. While they serve a practical purpose, some preservatives, particularly artificial ones, have raised concerns regarding their potential effects on health. Consuming foods high in artificial preservatives may contribute to oxidative stress and inflammation in the body, which can indirectly affect brain health. Chronic inflammation has been linked to cognitive decline and impaired memory function. While more research is needed to establish a direct causal link between preservatives and cognitive function, it’s advisable to prioritize whole, minimally processed foods and limit the consumption of foods with excessive artificial additives.

Lack of Nutrients:

A diet lacking essential nutrients can deprive the brain of the fuel it needs to function optimally. Nutrients such as omega-3 fatty acids, vitamins (particularly B vitamins), minerals (like iron and zinc), and antioxidants play vital roles in maintaining brain health. Omega-3 fatty acids, for example, are crucial for the structure of brain cell membranes and support cognitive functions such as memory and learning. A deficiency in nutrients can lead to cognitive impairments, reduced focus, and compromised mood regulation. Adopting a balanced diet rich in a variety of nutrient-dense foods is essential for providing the brain with the building blocks it requires to operate at its best.

Inadequate Water Intake:

Dehydration can have a swift and profound impact on brain function. The brain relies on proper hydration to maintain its delicate balance of electrolytes and neurotransmitters. Even mild dehydration can result in difficulties with concentration, memory recall, and cognitive tasks. Dehydration can lead to reduced blood flow to the brain, affecting overall cognitive performance. It’s essential to stay adequately hydrated throughout the day, as even a slight drop in hydration levels can lead to noticeable cognitive deficits.

Relevance for Neurodivergence and High Sensitivity

The significance of a balanced diet, adequate hydration, and minimizing the consumption of preservatives holds particular importance for neurodivergent individuals due to the unique ways in which their brains function. Neurodivergent individuals, such as those with conditions like ADHD, autism spectrum disorder (ASD), or other cognitive differences, often have distinct sensory sensitivities, processing styles, and cognitive needs that can be influenced by their nutritional intake. Here’s why these factors are crucial for neurodivergent individuals:

Sensory Sensitivities: Many neurodivergent individuals experience heightened sensory sensitivities. Artificial additives and preservatives found in processed foods can trigger sensory reactions and exacerbate sensory overload. Avoiding these additives can help reduce sensory stress, promoting a more comfortable and focused environment.

Cognitive Function: Neurodivergent individuals may have unique cognitive patterns and needs. Proper nutrition, including essential nutrients, can significantly impact cognitive function. Omega-3 fatty acids, for instance, have been linked to improved executive functions and mood regulation, which are areas often affected in neurodivergent individuals. A nutrient-rich diet can provide the brain with the tools it needs to support optimal cognitive processing.

Behavior and Mood: Diet can play a role in behavior and mood regulation. Neurodivergent individuals, particularly those with conditions like ADHD or ASD, may experience mood fluctuations or behavioral challenges. Nutritional imbalances can exacerbate these challenges. A well-balanced diet rich in nutrients can contribute to a more stable mood and behavior, potentially reducing the severity of symptoms.

Gut-Brain Connection: The gut-brain connection, also known as the gut-brain axis, is a bidirectional communication pathway between the gut and the brain. This connection is particularly relevant for neurodivergent individuals, as gut health has been linked to cognitive function, mood regulation, and even conditions like autism. A diet high in fiber, prebiotics, and probiotics supports a healthy gut, potentially positively impacting cognitive and emotional well-being.

Hydration and Sensory Regulation: Adequate hydration is crucial for sensory regulation, especially for individuals with sensory sensitivities. Dehydration can amplify sensory sensitivities and contribute to sensory overload. Staying hydrated supports overall sensory well-being, allowing neurodivergent individuals to better manage their sensory experiences.

Prioritizing a balanced diet, sufficient hydration, and avoiding artificial additives can have profound benefits for everyone but is particularly important for neurodivergent individuals. These factors can contribute to improved cognitive function, sensory regulation, mood stability, and overall well-being. Consulting with healthcare professionals who have experience working with neurodivergent individuals can provide tailored guidance for creating a nutritional plan that supports your unique needs while enhancing quality of life.

About Michelle

Hi I’m Michelle Marsh and I am a coach, therapist, Kundalini Yoga teacher and lover of life.

As Mum with ADHD and highly sensitive person who is also a sensation seeker, I understand what it’s like to have your sensitivity running your life instead of aiding it. But I also know from experience that there is light at the end of the tunnel if you are willing to do the work. For myself, I was never afraid of doing the work… I just couldn’t work out WHAT to do! After years of searching, a few burn outs/breakdowns and intense study I became clear on what works and what doesn’t.

But I am not just sharing with you from an experience point of view. I am also teaching from a professional stance as someone who has studied and integrated teachings from biological, psychological and esoteric traditions. These include Creative Therapies, Kundalini Yoga (KRI), Registered Nursing, Clinical Hypnotherapy, Plant Medicine and Natural Living.

I combine my naturally enthusiastic belief in EVERY BODY  with my natural empathic talents to provide you with just the right amount of space and direction so you can go deep and resurface anew.

During the time that I am your coach, I will not leave you hanging between sessions as I am available via email to answer questions and provide support as needed.

If you are unsure whether working with me is right for your unique circumstances, please reach out and I will help you to find clarity. I don’t do sales calls so our chat will be very casual and I will refer you in the right direction if I see that Aromanosis is not right for you at this time.
