Childhood obesity has become a significant health problem, putting children and adolescents at risk for developing asthma, high blood pressure, and type 2 diabetes, as well as other serious health risks. The American Academy of Pediatrics website has a parenting corner, helpful links, and resources on this topic. See their “Overweight and Obesity” section.
The Food and Drug Administration (FDA) and the Federal Trade Commission (FTC) issued warning letters to several companies selling unproven products claiming to treat, cure, and prevent sexually transmitted diseases (STDs). These products—such as Medavir, Herpaflor, Viruxo, C-Cure, and Never an Outbreak—violate federal law because the FDA has not evaluated them for safety and effectiveness. Some are marketed as dietary supplements, but the FDA considers them drugs since they are offered for the treatment of disease. More information is provided in the FDA Press Release.
We’re supposed to eat a lot of dark green vegetables, but beyond broccoli, what are some good options? For starters, pick a salad that has romaine or dark green leafy lettuce. Bok choy, collard greens, kale, mustard greens, spinach, turnip greens, and watercress are all good dark green vegetables that contain lots of nutrients. Variety is the key to an overall healthy diet, so don’t forget to include some dark green vegetables in your daily diet.
The FDA warns against weight-loss products which don't live up to their claims and can potentially cause serious harm. Dozens of products have been found being marketed as dietary supplements which contain hidden prescription drugs or compounds that have not been adequately studied in humans.
The Food and Drug Administration (FDA) has found nearly 300 fraudulent products–promoted mainly for weight loss, sexual enhancement, and bodybuilding–that contain hidden or deceptively labeled ingredients.
The Food and Drug Administration (FDA) has proposed calorie labeling for chain restaurants and similar retail food establishments, as well as for vending machines. The move is a response in part to the obesity problem in the U.S. and is seen as a way for consumers to have consistent nutritional information when they make food choices.

Red 40, Yellow 5, Yellow 6, and other dyes are artificial colorings allowed in foods in the U.S., yet there is a long-standing debate over whether food dyes contribute to hyperactivity in children. The Food and Drug Administration’s (FDA) Food Advisory Committee met the last week of March and determined that there is not enough evidence to support the link between food dyes and hyperactivity in children. For now, there will be no warning labels on food products containing dyes.
You may have heard time and time again that breakfast is the most important meal of the day and that eating a big breakfast could help you lose weight. One explanation for this claim is that starting the day with a big breakfast prevents food cravings and induces weight loss. Is this true? And is there scientific evidence to support this claim?
Some scientific findings suggest that consuming an energy-rich breakfast causes a person to eat less during the rest of the day. Other findings suggest that increasing the size of breakfast is linked to overall greater food intake. A WebMD article examined this conflicting evidence in light of a recent study conducted by a group of German scientists at the Else-Kroner-Fresenius Center of Nutritional Medicine, Technical University of Munich. Naturally, a study has to be well designed and executed in order for the results to hold up to scrutiny by the scientific community. In this case, which involved a large group of participants, several measures were introduced to encourage accurate record keeping and sound statistics to analyze the results.
Generally speaking, the study suggests that individuals who consume bigger breakfasts in hopes of losing weight may actually end up consuming more calories than anticipated, as they are likely to eat the same amounts of food during lunch and dinner that they would following a small breakfast. This particular finding is worth sharing because it creates awareness of this behavior and may encourage people to consciously watch what they eat for lunch and dinner if they do have a big breakfast or, alternatively, reduce the size of their breakfast. This could be a key for people in their efforts to maintain or lose weight.
All the same, we wish to remind readers that there is no magic formula when it comes to losing weight. Well, maybe there is…
Higher Caloric Expenditure + Lower Caloric Intake = Weight Loss
This is a good general formula to keep in mind in your efforts to lose or maintain your weight. So for instance, while being physically active increases your caloric expenditure, reducing a high-fat diet lowers your caloric intake. And in this instance, refraining from eating a bigger breakfast than usual could contribute to reducing your caloric intake for the day.
In short, we encourage you to eat regular, healthy meals. However, if you decide to eat a bigger-than-usual breakfast, balance it out by eating less during the rest of the day. We hope that the results of this study help you make informed decisions about the number of calories you consume for breakfast.
Following a lead from First Lady Michelle Obama to combat obesity, several beverage-industry companies are voluntarily putting the total calories on the front labels of their non-alcoholic beverages. The American Beverage Association’s 2010 “Clear on Calories” initiative directed that beverage containers of 20 ounces or less carry total calories, while larger containers identify calories per 12 ounces, with full implementation by 2012. For more information, read a news release about this new initiative.
Heart disease is the number-one killer for both men and women. A well-balanced diet, along with regular exercise, can reduce the risk of heart disease. New heart disease guidelines were recently issued, with particular focus on illnesses that increase the risk of cardiovascular disease in women. For more information, read the news release and information about the new guidelines, which include information about the American Heart Association’s “Go Red for Women” campaign.
