It Might Be Toxic

1 Is Your Supplement Safe?

While supplements line store shelves and consumers’ medicine chests, Chemical & Engineering News Senior Editor Celia Henry Arnaud proposes that many of these products may be neither safe nor effective. In fact, suggests Arnaud, they may even be toxic, containing high levels of mercury, lead or pesticides. Plus, they may have a negative reaction with certain conventional drugs. The US Food and Drug Administration classifies dietary supplements as foods rather than drugs and therefore, does not require the same stringent testing as for conventional medications. However, the FDA recently required that supplement manufacturers test their products for contaminants. Says the article, ongoing research will provide more information to determine the long-term safety of supplements.

Healthy After School Snacks Help

2 Whole Grains Missing from Kids’ Diets

Research indicates that children typically eat one serving of whole grains per day although federal nutrition guidelines recommend at least three servings per day for optimal health. Now, a new study from the University of Minnesota shows that kids, given the choice between processed graham crackers or graham crackers with a much higher content of whole grains, don’t have a preference even though it’s largely thought that kids stay away from whole grains because they don’t like the taste or texture. "Graham snacks provide a healthy, highly acceptable whole grain food that kids love to eat," says Len Marquart, the lead investigator on the study." This is an excellent way for kids to get up to an additional serving of whole grain per snacking occasion."

Ozone Bad for the Heart

3 Ozone May Increase the Risk of a Heart Attack

Preliminary tests suggest that rats who are exposed to ozone over several weeks increased the activity of tumor necrosis factor alpha (TNF-A), which is a marker of inflammation. Previous studies have shown the when TNF-A increases, a protein that protects the heart called Caveolin-1 (Cav1) by inhibiting a protein that causes heart cells to die. Levels of Cav1 were lower in rats exposed to ozone compared to the group who were exposed to filtered air. Several studies have linked pollution to ateriosclerosis and heart attack. Dr. Len Horovitz, a pulmonary specialist, says "Now there is evidence (in rats) that ozone...can trigger a direct effect on cardiac tissue through a cascade of inflammatory mediators. The endpoint in this domino effect can result in death of heart cells."
