Neurologist Elena Surskaya explained that glucose plays a critical role in supporting brain function. The information was relayed by aif.ru. The core idea she shared is that the foods people choose can influence mental sharpness, memory, and learning capacity. In this context, she warned that certain popular snacks and drinks can deliver carbohydrates that do not support brain health when consumed in excess. High-glucose items like chips, sweet sodas, baked goods, and energy drinks tend to supply fast-burning sugars that can lead to short bursts of energy followed by dips, making it harder to focus and retain information over time.

She emphasized that the brain relies on steady energy from carbohydrates to maintain concentration and cognitive performance. When the intake is dominated by quick-release sugars, the brain may struggle to keep up with tasks that require attention, planning, and memory formation. In contrast, deliberate food choices supporting brain health help provide a more stable energy supply, supporting sustained mental effort throughout the day.

According to Surskaya, the best sources of carbohydrates for brain health come from nutrient-dense foods such as nuts, whole grains, and a variety of vegetables. These foods release glucose more gradually, helping to maintain stable blood sugar levels and steady brain energy. Alongside healthy carbohydrate choices, she recommends lean proteins like boiled poultry, fish, and low-fat dairy, which supply amino acids essential for neurotransmitter production and brain repair processes. Adequate sleep also plays a crucial role in cognitive function, memory consolidation, and overall brain health—complementing a balanced diet for better daytime performance.

In related research, studies conducted by scientists in the United States have highlighted the connection between cognitive performance and the ability to judge spatial relationships, write coherently, and recognize moving and stationary objects. These faculties can be affected by neurological changes that sometimes precede more serious conditions. While correlation does not prove causation, such findings underscore the importance of maintaining overall brain health through a combination of diet, physical activity, and mental stimulation as people age.

Additionally, there has been ongoing discussion in the medical community about various myths related to asthma and severe Covid-19 in children. Recent reviews by clinicians have aimed to clarify believed associations, emphasizing the need for evidence-based guidance. This ongoing discourse reflects the broader context in which health information evolves, and it highlights the importance of consulting qualified healthcare professionals for diagnoses and personalized recommendations.”
