FDA Revises, Strengthens Sunscreen Regulations

In an effort to ensure that consumers have the information they need to make wise sun protection choices, the Food and Drug Administration (FDA) recently announced an updated list of sunscreen regulations [1].

Q&A: Is “Wheat Flour” Whole Wheat, And Why Does It Matter?

Question: Is whole wheat considered a whole grain? As I understand it, foods with a low glycemic index are supposed to leave you feeling fuller, take longer to digest, and have health benefits. I thought whole grains were supposed to do those things too, but I’ve also read on the Internet that there’s no difference between wheat flour and white flour. What’s the truth?

Flu Shot During Pregnancy Improves Perinatal Outcomes

During pregnancy, women need to take special care to avoid becoming ill. There are several reasons for this. The first is that a pregnant woman’s immune system is not as strong during pregnancy as it generally is; this helps to prevent the mother’s body from attacking the developing fetus. Unfortunately, however, the weakened immune system also means that pregnant mothers are more susceptible to pathogens that they’d otherwise fight off relatively easily. Increased susceptibility aside, there’s also the concern that some illnesses — influenza included — can impact the developing fetus. Finally, there’s the simple fact that many of the medications used to treat illnesses and their accompanying symptoms aren’t appropriate for pregnant women.

Android App for Those Concerned about Cell Phone Radiation

While the link between cell phone use and brain tumors has not been scientifically established — in fact, a recent U.K. Health Protection Agency group review of the scientific literature concluded that there’s no convincing evidence that cell phones cause cancer — concerns about overexposure of brain cells to radiofrequency waves (RF) from cell phone antennae continue to circulate. While there may not be a well-established link between cell phone use and cancer or tumors, there’s nevertheless evidence that cell phone use alters brain cell metabolism (the rate at which brain cells burn sugar for energy) [1]. The significance of this finding is currently unknown, which makes some cell users nervous.

A company called Tawkon (pronounced “talk on”) has developed an app for the Android phone that can predict — not detect, since phones don’t have the ability to detect radiation — when a phone is most likely to be emitting high levels of RF on the basis of internal measurements, such as how strong the cell signal is.

No Convincing Evidence that Cell Phones Cause Cancer

A new report by the U.K. Health Protection Agency’s independent Advisory Group on Non-ionising Radiation (AGNIR) has concluded that there is no convincing evidence that mobile phone technologies cause adverse effects on human health. The report updates AGNIR’s previous review in 2003 that considers the scientific evidence on exposure to radiofrequency (RF) electromagnetic fields, which are produced by mobile phone technologies and other wireless devices, such as Wi-Fi, as well as television and radio transmitters.
