Epigenetics is the study of changes in organisms, it is caused by modification of gene expression. DNA doesn’t compose the helical structure of the human genome. Epigenes lies above the genome adding another layer to the spiraled genetic structure. Due to environmental factors such as stress, cigarette smoking, and food alter epigones to change the structure of genes. These epigenetic modifications activate and deactivate genes in ways that help or harm a person’s health. Food is one essential way in which a person can control their epigenetic (Gaynor, 2014).
The article Understanding nutrition, depression, and mental illnesses describe how depression is thought of as strictly biochemical based or strong feelings. However, nutrition plays a major role before and during depression. Studies show that there is a food pattern that comes before depression this is the same as those that occur during depression. For example, poor appetite, skipping meals, and desire for sweet foods. (Rao, T. S., Asha, M., Ramesh, B., & Rao, K. J, 2008)
“Depression is a mental illness that is characterized by negative thoughts and behaviors. It is a disorder that has symptoms such as increased sadness, anxiety, loss of appetite, depressed mood, and a loss of interest in pleasurable activities” (Parekh, 2017).
Some treatment options may include medications, therapy, and self-care. Examples of self-care include sleep, physical activity, and diet. Needless to say, nutrition has a major effect on human cognitive abilities, behavior, and emotions (Tello, 2018).
