The Connection Between What We Eat and Our Brains Throughout the Whole Life Journey

The burden of cognitive impairment and mental illnesses is increasing daily because of modern lifestyles. Many studies have been conducted to understand the pathology of cognitive impairment and mental illness. Based on a good understanding of that pathology, many studies were conducted to determine if nutrition can play a role in hastening the progression of cognitive impairment and mental illness. Some studies were conducted to determine whether some cognitive impairment conditions or mental illnesses can be prevented from the start, especially when it comes to certain diseases that represent a real burden on society, such as AD, dementia, and major depressive disorders. Other studies have shown the possibility of attaining better cognitive abilities and improving individuals’ cognition and mental health. This will be reflected in the productivity of each individual in society, regardless of their age. Although observational studies that examine the role of nutrition in mental health and cognition are diverse and the correlation between diet and brain development is obviously significant; unfortunately, there are few high-yielding RCTS. Consequently, the causal relationship between nutrition and brain function has not yet been concluded. In this chapter, we will discuss the harmony between the food we have daily and our brains.
