Epigenetics and their role in the development of chronic diseases is turning into one of the most significant issues in the contemporary health science. During the past few years, people used to think that genes were the sole determinants of the occurrence of some diseases among individuals. Scientists believed that when a person inherited bad genes, there was little that he can do about the situation.
Nonetheless, this has not been entirely true as indicated by recent research. Epigenetics describes the way lifestyle, surroundings and everyday habits can affect the behavior of the genes without any alteration of the DNA structure. I am interested in this subject as it demonstrates how our everyday decisions can impact our health in either strong or weak ways.
Epigenetics is the term that defines changes in the chemical manner of switching the gene on or off. Within the body of each individual there are thousands of genes. These genes contain a code of how cells develop, repair and operate. Nonetheless, all genes do not occur simultaneously.
Epigenetic modification is a switch like a control of gene activity. These switches are known to be influenced by diet, stress, pollution, smoking and physical activity among the factors that scientists have discovered. The molecular biology research has demonstrated that these alterations can influence the behavior of cells and may be the cause of chronic diseases.
Among the scientific facts that can be discussed is that epigenetic changes can regulate inflammation within the body. Heart disease, diabetes, and cancer are some of the diseases associated with chronic inflammation. Medical journal publications have demonstrated that unhealthy foods, particularly, high-sugar processed foods, can cause epigenetic alterations, which raise levels of inflammation.
I have also come to know that some of the inflammation-related genes are more activated when individuals maintain a constant consumption of unhealthy food. This may ruin tissues and organs in the long run resulting in chronic illness.
Another significant contributor of epigenetics is stress. It has been demonstrated by research in psychological and neuroscience disciplines that chronic stress may alter the functioning of genes that are associated with the immune system. The body also releases stress hormones like cortisol when an individual is under constant stress (emotional or physical).
Chronic cortisol may induce epigenetic alterations to prolonged effects that suppress the immune system. Researchers have established that individuals who undergo chronic stress tend to acquire conditions such as hypertension, depression, and autoimmune diseases. I consider it significant personally since it demonstrates that emotional health is related closely to physical one.
The exposure of the environment is also very strong in epigenetic changes. Research has demonstrated that gene expression can be changed by exposure to pollution, toxic chemicals and cigarette smoke. As an illustration, environmental health studies have established that air pollution has the ability to turn on genes that predispose individuals to respiratory infections and heart ailments.
Epigenetic modifications can also be transferred to unborn children by pregnant women who are exposed to dangerous chemicals. This implies that the environmental factors can have an impact on the intergenerational level of health, and epigenetics is an extremely serious issue in terms of the overall health of the population.
Another noteworthy field of study reveals that the harmful epigenetic outcomes can be reversed because of the positive lifestyle choices. Nutrition and preventive medicine scientists have discovered that the activity of the genes can be enhanced by healthy eating, physical activities, and stress control.
Healthy fats, whole grains, fruits, and vegetables are the sources of nutrients that promote a healthy expression of genes. That exercise can also kill genes which enhance metabolism and dampen inflammation is also evidenced. I am optimistic about this study as it demonstrates that individual genetic makeup does not entirely determine people.
Epigenetics is also affected by sleep and mental wellness. Sleep medicine research indicates that bad sleeping habits may influence genes that deal with metabolism, brain activity, and immune system.
The lack of enough quality sleep among people can lead to the development of epigenetic changes by their bodies that put people in danger of developing obesity, diabetes and other mental health disorders. Healthy sleep routines allow controlling the activity of the genes and promote good health.
To sum up, epigenetics has a significant part in the pathogenesis of chronic diseases through the regulation of gene expression. It has been scientifically established that, lifestyle, emotional stress, and exposure to the environment, diet, as well as sleep patterns can all affect the activity of the genes.
Genetics gives the blueprint of the body, whereas epigenetics assists in the utilization of the blueprint. In my opinion, this knowledge is effective since it motivates individuals to become aware of their health. Through healthy lifestyles, people can lower chances of being exposed to chronic conditions and enhance their health status.
