A healthy diet provides better brain function. The brain is the largest organ of the central nervous system and is part of the control center for the entire body. It is perhaps the most complex organ of all, as it is responsible for thinking, emotions, memory, and language, in addition to physical aspects. Due to the daily grind and everything we have 'on our minds,' we have all experienced the situation of forgetting something at some point. Even during conversations, it is common to want to say something but not find the words, or we can't remember the name of something or someone. For this reason, a group of researchers from McMaster University in Canada, in conjunction with the National University of Ireland in Galway, conducted a study in which they concluded that a healthy diet allows the brain to have better cognitive function, unlike those who, due to their lifestyle, neglect their eating habits. The test was conducted on 27,680 people; volunteers over 55 years old with elevated cardiovascular risk for five years, during which they discovered that beyond exercise and a busy or relaxed life, it is food that ultimately influences cognitive performance, for better or for worse. Eating fruits, vegetables, fish, nuts, and decreasing red meat consumption resulted in better outcomes in skill, thinking, and memory tests for those who took care of their diet, as well as a moderate level of alcohol. These tests were carried out at the beginning, halfway through, and at the end of the study, which concluded in the words of Andrew Smyth, (who led the study) that diet is directly associated with memory loss and cognitive function, to the extent of reaching a 24% lower risk among those who take care of their diet compared to those who do not, regardless of whether they practice any sport or physical activity. “Dietary intake can modify the risk of cognitive decline through multiple mechanisms, including an increased risk of stroke and through the deficiency of the necessary nutrients for neuronal regeneration. In conclusion, a higher quality diet is associated with a lower risk of cognitive decline. Improving diet quality represents an important potential goal to reduce the global burden of cognitive decline,” commented the researcher. It is often said that “we are what we eat,” and at least science shows us that they are correct. While physical activity and trying to avoid stress are important aspects, our diet is the foundation of everything to prevent problems in the short and long term. So as a certain bookstore would say, “Eating well will prevent you from saying ‘it’s on the tip of my tongue.’” It is worth mentioning that the results of the studies conducted by both educational institutions were published in the journal Neurology.
