For example, salami and cooked beef have similar total moisture (approximately 60%). Products with the same water content may have very different water activities. ![]() Foods with higher moisture content might be expected to have higher water activity than dry foods but the expectation is not necessarily correct. The relationship between total moisture and water activity is complex, is related to the relative humidity of the food and its water content and must be determined for each specific food. Water activity is a good predictor of food safety and of how long a food product will last on the shelf. Water activity is controlled by removing water (drying or freezing), by adding salt (curing) or by adding sugar (jams, jellies). Water activity (Aw) describes water available for microbial growth and ranges from 0 (bone dry) to 1.0 (pure water). Moisture in foods occurs in two forms: (1) water bound to ingredients in the food (proteins, salt, sugars), and (2) free or unbound water that is available for microbial growth. Read on about the dangers of sexting from Everyday Health’s medical director, Mallika Marshall, MD.Food preservation methods such as drying, freezing and adding salt or sugar work by lowering the available moisture in foods. You may also want to consider monitoring cell phone and computer use for further inappropriate behavior, and contacting the parents of the other child involved. Then make a plan to check in with your child about his or her text habits in the future. Talk with your teen about why and with whom they’re exchanging such messages, and discuss the potential consequences of their actions. If you spot any of these messages on your child’s phone, don’t just get angry and take away his or her text privileges. Here are just a few of the many (many!) examples of shorthand that teens and tweens use to sext: A lot of sexting is done in code, using acronyms and decoy words. But do you know what those flags are? Many sexually explicit messages aren’t actually that explicit - to parents, anyway. If you have teens, you’re likely already on the lookout for red flags. ![]() ![]() Sexting, the transmission of such messages and images, primarily between cell phones, is an increasing concern among parents - and though the study released today indicates it’s not as widespread a problem as we’d previously feared, such behavior can have serious consequences, not just for your child’s emotional well-being and privacy, but from a legal standpoint as well. But even more - up to 39 percent, according to a survey by the National Campaign to Prevent Teen and Unplanned Pregnancy - have sent or received sexually suggestive messages, such as texts, e-mails, or IMs. 5, 2011 - Some 10 percent of tweens and teens have exchanged sexually suggestive photos via phone, the Internet, or other electronic media, according to a new study just published in the journal Pediatrics.
