Impact of ultra-processed foods on health and neurocognitive function. Such needs include the demands of changing modern lifestyle, increasing change in working patterns and increasing travel, which has led to increased demand for long-lasting convenience foods. Food items are developed and designed to suit diverse cultures, convenience and ease of consumption.
nutritional deficiencies
To meet these demands, the use of food additives, preservatives and artificial colors has increased. Nevertheless, excessive and prolonged consumption of such substances leads to essential nutrient deficiencies and adverse effects on neurocognitive health. Ultra-processed foods contain artificial colors, benzoates, non-caloric sweeteners, and emulsifiers, all of which have adverse effects on mental health, including reduced attention span, cardiovascular problems, metabolic disorders, and long-term neurocognitive decline.
gut microbiota
Researchers have linked these chemicals to oxidative stress, neuroinflammation, and interference with neurotransmitter synthesis and ion transport. Animal studies have shown that these chemicals can also interfere with the gut microbiota, indirectly reducing the production of important neurotransmitters. The gut talks to the brain via the vagus nerve, and disruption of the gut microbiota impairs ion channel and neurotransmitter levels, making the condition worse.

Depression
Chronic exposure to these substances can lead to neurocognitive decline, which manifests as depression, anxiety, attention deficit, aggression, and dementia. Over time, such dietary patterns may contribute to degenerative conditions such as Parkinson’s, Alzheimer’s, and other types of dementia. Additionally, these foods can disrupt hormonal balance, leading to thyroid dysfunction, which can have potentially lifelong cognitive consequences, especially in children and adults.
For long-term health, a balanced diet with plenty of green leafy vegetables, vitamin-rich fruits and essential nutrients is essential. To reduce health risks and enhance cognitive well-being, long-preserved foods should be limited and processed meats, red meat, sugary drinks, fried fast foods, and alcohol should be avoided.
