healing through fasting

We will fasting soon. However, is it can heal us or give bad effect on our body??

Our body is a tube and membrane structure containing millions of miles of microscopic tubes and many thousands of square feet of delicate membrane surfaces. The circulatory system is 60,000 miles long. The lungs contain 300 billion capillaries. The surface area of the colon is 2,200 square feet. People who eat the typical North American diet are not ingesting nutritious, health-giving food; instead, what enters the delicate tube and membrane structure is devitalized mucus-forming food, heavy proteins, cholesterol, and big sticky long-chain fat molecules. The body is denied the opportunity to heal because it must continually work at digestion and the daily cleanup of nutrition-stripped, processed foods.
During a fast, a metamorphosis occurs. The body undergoes a tearing down and rebuilding of damaged materials. There is a remarkable redistribution of nutrients in the fasting body. It hangs on to precious minerals and vitamins while catabolizing old tissue, toxins and inferior materials. The end result is a thorough cleansing of the tube, membrane and cellular structures. This process of cleansing and rebuilding has made fasting famous for its ability to rejuvenate, heal disease and give the body a more youthful tone. So, we should welcome the Ramadhan, fasting month that can benefit our bodies...
