Nuts are a delicious part of an anti-aging diet, helping you ward off chronic diseases like cardiovascular disease, diabetes, and certain cancers—and thanks to a review of two large-scale, long-term studies published in the New England Journal of Medicine in 2013, there's strong evidence that nuts of all kinds can help you live longer, too. In that research, eating just an ounce of nuts daily was linked to a 20 percent lower risk of death over a 30-year period. Nuts and General Health   Nuts have been a regular component of the human diet for thousands of years. A growing body of evidence that nuts are healthy prompted the U.S. Food and Drug Administration (FDA) in 2003 to issue a qualified health claim saying that current scientific data suggest that eating 1.5 oz (42g) of nuts each day may reduce the risk of heart disease. More recent research has shown that eating nuts is linked to a lower risk of colon cancer, gallbladder disease, and diverticuliti...

What Are Antibodies? Antibodies (also called immunoglobulins) are specialized proteins that travel thorough the blood stream and are found in bodily fluids. They are utilized by the immune system to identify and defend against foreign intruders to the body. These foreign intruders, or antigens, include any substance or organism that evokes an immune response. Bacteria, viruses, pollen, and incompatible blood cell types are examples of antigens that cause immune responses. Antibodies recognize specific antigens by identifying certain areas on the surface of the antigen known as antigenic determinants. Once the specific antigenic determinant is recognized, the antibody will bind to the determinant. The antigen is tagged as an intruder and labeled for destruction by other immune cells. Antibodies protect against substances prior to cell infection. Antibody Production Antibodies are produced by a type of white blood cel...

White blood cells are blood components that protect the body from infectious agents. Also called leukocytes, white blood cells play an important role in the immune system by identifying, destroying, and removing pathogens, damaged cells, cancerous cells, and foreign matter from the body. Leukocytes originate from bone marrow stem cells and circulate in blood and lymph fluid. Leukocytes are able to leave blood vessels to migrate to body tissues. White blood cells are categorized by the apparent presence or absence of granules (sacs containing digestive enzymes or other chemical substances) in their cytoplasm. A white blood cell is considered to be a granulocyte or an agranulocyte. Granulocytes There are three types of granulocytes: neutrophils, eosinophils, and basophils. As seen under a microscope, the granules in these white blood cells are apparent when stained. Neutroph...

Blood is the life giving fluid that delivers oxygen to the cells of the body. It is a specialized type of connective tissue that consists of red blood cells, platelets, and white blood cells suspended in a liquid plasma matrix. Did you know that blood accounts for about 8 percent of your body weight or that blood contains small amounts of gold?  While humans have red colored blood, other organisms have blood of varying colors. Crustaceans, spiders, squid, octopuses, and some arthropods have blue blood. Some types of worms and leeches have green blood. Some species of marine worms have violet blood. Insects, including beetles and butterflies, have colorless or pale-yellowish blood. The color of blood is determined by the type of respiratory pigment used to transport oxygen via the circulatory system to cells. The respiratory pigment in humans is a protein called hemoglobin found in red blood cells. Your body contains about a gallon of bloo...
