Abstract
The relationship between diet and brain health, particularly in terms of intelligence quotient (IQ) and brain development, has been a topic of interest for researchers. This study aims to explore various diets that have been linked to enhancing IQ and promoting brain development. The Mediterranean diet, known for its emphasis on whole grains, fruits, vegetables, fish, and healthy fats, has shown promising results in improving cognitive function and reducing the risk of neurodegenerative diseases. Additionally, the DASH (Dietary Approaches to Stop Hypertension) diet, which focuses on reducing sodium intake and increasing consumption of fruits, vegetables, and low-fat dairy products, has been associated with better cognitive performance. Furthermore, specific nutrients such as omega-3 fatty acids, found in fish and nuts, have been found to play a crucial role in brain development and cognitive function. Studies have also highlighted the importance of antioxidants, vitamins, and minerals in protecting brain cells from damage and supporting optimal brain function. Moreover, the role of hydration in brain health should not be underestimated, as even mild dehydration can impair cognitive performance. In contrast, diets high in processed foods, sugar, and saturated fats have been linked to cognitive decline and poorer brain health. The Western diet, characterized by the consumption of red meat, sugary snacks, and fried foods, has been associated with an increased risk of cognitive impairment and neurodegenerative diseases. Excessive alcohol consumption and inadequate hydration can also negatively impact brain function and cognitive abilities. Overall, the findings suggest that a balanced diet rich in nutrients such as omega-3 fatty acids, antioxidants, vitamins, and minerals can support brain health and enhance cognitive function. Adopting dietary patterns like the Mediterranean diet or DASH diet may offer protective effects against cognitive decline and promote optimal brain development. However, further research is needed to better understand the specific mechanisms through which different nutrients and dietary patterns influence IQ and brain health. Ultimately, maintaining a healthy diet and staying hydrated are key factors in supporting cognitive function and maximizing brain potential throughout the lifespan.
