Hygiene—keeping both home and body clean—is one of the best ways to curb the spread of bacterial infections, but lately consumers are getting the message that washing with regular soap is insufficient. Antibacterial products have never been so popular. Body soaps, household cleaners, sponges, even mattresses and lip glosses are now packing bacteria-killing ingredients, and scientists question what place, if any, these chemicals have in the daily routines of healthy people. <p></p></span></p><p class="MsoNormal" style="margin: 0cm 0cm 0pt; direction: ltr; unicode-bidi: embed; text-align: left; mso-margin-top-alt: auto; mso-margin-bottom-alt: auto" align="left"><span style="font-size: 10pt; color: #3366ff; font-family: arial">Traditionally, people washed bacteria from their bodies and homes using soap and hot water, alcohol, chlorine bleach or hydrogen peroxide. These substances act nonspecifically, meaning they wipe out almost every type of microbe in sight—fungi, bacteria and some viruses—rather than singling out a particular variety.<p></p></span></p><span style="font-size: 10pt; color: #3366ff; font-family: arial"><p class="MsoNormal" style="margin: 0cm 0cm 0pt; direction: ltr; unicode-bidi: embed; text-align: left; mso-margin-top-alt: auto; mso-margin-bottom-alt: auto" align="left"><br />Continuing on:</p></span><span style="font-size: 10pt; color: #3366ff; font-family: arial"><a href="http://www.sciam.com/article.cfm?articleid=024FEAE8-E7F2-99DF-323D8E02C4E48BF6"><span style="color: #3366ff"><p class="MsoNormal" style="margin: 0cm 0cm 0pt; direction: ltr; unicode-bidi: embed; text-align: left; mso-margin-top-alt: auto; mso-margin-bottom-alt: auto" align="left"><br />http://www.sciam.com/article.cfm?articleid=024FEAE8-E7F2-99DF-323D8E02C4E48BF6<p></p></p></span></a></span><p class="MsoNormal" style="margin: 0cm 0cm 0pt; direction: ltr; unicode-bidi: embed; text-align: left; mso-margin-top-alt: auto; mso-margin-bottom-alt: auto" align="left"><span style="font-size: 10pt; color: #3366ff; font-family: arial"><p> </p></span></p>

The next morning he wakes up with red bumps roiling over his skin. Is there a connection? Did eating all that greasy food give him a bad case of the zits? The simple answer for the past 30 years has been a resolute no. But today, new research suggests the answer is more complicated: maybe.<br /> <p></p></span></p><p class="MsoNormal" style="margin: 0cm 0cm 0pt; direction: ltr; unicode-bidi: embed; text-align: left; mso-margin-top-alt: auto; mso-margin-bottom-alt: auto" align="left"><span style="font-size: 10pt; color: blue; font-family: arial">The fat you put in your mouth does not reappear on your skin. When you eat, the food goes through the digestive system, which breaks down that fried chicken into nutrients that can be easily absorbed and utilized. Bile acids dissolve fat in water in the intestinal cavity. Enzymes break the larger fat molecules into smaller ones. Cell walls absorb these molecules, which are then transported to the veins in the chest and fat storage areas around the body.<p></p></span></p><span dir="rtl" style="font-size: 10pt; color: #3366ff; font-family: arial; mso-fareast-font-family: &quot;times new roman&quot;; mso-ansi-language: en-us; mso-fareast-language: en-us; mso-bidi-language: ar-sa"><a href="http://www.sciam.com/"><span dir="ltr"><p align="left"><br />www.sciam.com</p></span></a></span>
