Fasting Can Regenerate Your Immune System
Fasting literally to totally abstain from in take of any food. It is the process of abstaining from consumption
of solid food, sometimes even liquids, for spiritual, medical or
experimental reasons. Religious scriptures describe the process of
fasting as a medium to make us realize the fragility of our existence
and how much we depend on things beyond ourselves for survival.
However, in the medical literature, the effects of fasting have been highly debated. Some scientists believe and propagate depriving the human body of the food, which is responsible for production of energy in the body, causes weakness and fatigue. On the other hand, recent scientific researches have concluded that abstaining from meals for a certain period of time can actually help in regeneration of the immune system in human body!
Far from being a potential hazard for health which many label it as, fasting has been proved in recent studies to boost the immune system and regenerate it entirely. As remarkable as it sounds, it is an exercise that is absolutely cost free too. Even intermittent abstinence from consuming food, for a small period of 8-10 hours, can prove to be beneficial for the overall health of the body. To evaluate the history of mankind, in ancient times regular meals were not accessible. Food was eaten when available, rest of the times were spent on an involuntary fasting. Until a prey was caught for meals, our ancestors went for long with the absence of food.
And, they evidently lived healthier lives. A hypothesis given by scientist Valter Longo, based on extensive studies describes the benefits of fasting. When the body is starving, the whole system functions to conserve energy stores of the body by recycling the unwanted immune cells of the body, majorly the damaged ones, and saving energy. This decrease in the number of white blood cells triggers the stem cells to form new immune cells. The enzyme protein kinase A (PKA) and IGF-1 levels are reduced in the body during fasting, which leads to a transduction change in the hematopoietic stem cells that promote self-renewal and regeneration. PKA enzyme is also related to aging, so the decrease in its levels promotes anti-aging.
Prolonged period of fasting forces the body to use the stores of fats and glucose. The benefits of fasting can prove beneficial for patients who have undergone chemotherapy or are susceptible to diseases or even for the people seeking anti-aging treatment.
The basic mechanism of destruction of the unwanted population of white blood cells and replacement of these old cells by triggering a fresh release of new immune system cells, aids in the regeneration of the immune system.
The dietary intervention in the patients who have undergone chemotherapy is, however, being further evaluated, before being suggested for use in patients.
Other harmful effects of chemotherapy may be mitigated by fasting, hence dietary changes should be made only after proper diet consultation from the physician.
A 72-hr fasting period is a long time period, and can be very difficult for a normal, healthy person to follow.
To avoid any hypo-glycemic episodes, prior expert consultation is advised.
Mild side effects like feeling of fatigue or drowsiness can be experienced while fasting.
Other important factors to be ensured prior to a long fasting period is that a person should consume a liquid diet 2 days before fasting.
This prepares the body to sustain during the absence of food during the 3-days fasting period.
Currently, research work is being conducted to study the benefits of fasting on other parts of the body apart from the immune system.
