In short, fiber is material that cannot be digested, and it acts like a sponge. It draws water from its surroundings, making it swell, which softens stool and adds bulk to it, which in turn helps it pass. Like coffee, some kinds of fiber (like beans) can contribute to constipation, so always drink plenty of water.
The immune system can distinguish between normal, healthy cells and unhealthy cells by recognizing a variety of danger cues called danger-associated molecular patterns (DAMPs). Cells may be unhealthy because of infection or because of cellular damage caused by non-infectious agents like sunburn or cancer.he immune system can distinguish between normal, healthy cells and unhealthy cells by recognizing a variety of danger cues called danger-associated molecular patterns (DAMPs).

The immune system is made up of specialized cells and proteins. Some of these specialized cells include white blood cells such as lymphocytes (B cells and T cells) and phagocytes (neutrophils, monocytes, and macrophages). White blood cells are produced in the bone marrow. The complement system is a group of proteins found in the blood that are critical in defense against infection. When the immune system is missing any of these parts, people are vulnerable to specific types of diseases.
