Skip the Supplements
PARENTS whose children are admitted to our hospital occasionally bring along something extra to help with their care: dietary supplements, like St. John’s wort to ameliorate mild depression or probiotics for better health. Here’s the problem: The Joint Commission, which is responsible for hospital accreditation in the United States, requires that dietary supplements be treated like drugs. It makes sense: Vitamins, amino acids, herbs, minerals and other botanicals have pharmacological effects. So they are drugs. Read More.

New concerns about the safety and quality of herbal supplements
If there is one aspect of “alternative” medicine that both critics and fans should agree on, it’s that products should be manufactured to high standards. What’s on the label should accurately describe what’s in the bottle. Product quality standards are essential, whether you’re using herbs or drugs. And when it comes to ensuring the products we buy are of high quality, we’re all effectively reliant on regulation to protect us. As a pharmacist, I can’t personally verify that each tablet in your prescription contains the active ingredient on the label. Read More.

Mosquito repellents from skin secretions
Those plagued by mosquitoes may one day be able to ditch the DEET in favour of substances naturally produced by skin, according to researchers in the US. Ulrich Bernier, and colleagues, at the US Department of Agriculture’s Agricultural Research Service, have identified compounds that scramble the senses of mosquitoes so they can’t detect people nearby. They say safer, more effective repellents based on these substances could help reduce the spread of mosquito-borne diseases like malaria. Read More.
Egg yolk consumption and carotid plaque
Increasingly the potential harm from high cholesterol intake, and specifically from egg yolks, is considered insignificant. We therefore assessed total plaque area (TPA) in patients attending Canadian vascular prevention clinics to determine if the atherosclerosis burden, as a marker of arterial damage, was related to egg intake. To provide perspective on the magnitude of the effect, we also analysed the effect of smoking (pack-years). Read More.
Stop Trashing Eggs: Large Study Finds No Harm
No food has had more ups and downs over the last century or so than the common egg. Following a long period in which eggs were ubiquitous and highly regarded, eggs fell from favor with the rise of concerns over cholesterol. Currently the American Heart Association recommends that people restrict dietary cholesterol to 300 mg per day, which effectively limits people to 1 egg per day at most. However, the relationship of dietary cholesterol and serum cholesterol is, at best, tenuous, and a significant number of experts now believe that egg consumption poses no risk to cardiovascular health.

Food is main source of BPA for consumers, thermal paper also potentially significant
EFSA's scientific experts have provisionally concluded that for all population groups diet is the major source of exposure to bisphenol A (BPA) and exposure is lower than previously estimated by EFSA. BPA is a chemical compound used in food contact materials such as packaging as well as in other consumer products. This is the Authority's first review of exposure to BPA since 2006 and the first to cover both dietary and non-dietary sources (including thermal paper and environmental sources such as air and dust).
