Recently, The Dr. Oz Show aired an episode that addressed the "Secrets of the Fast Food Industry." We had some questions about the episode, so we reached out to Dr. Sean O'Keefe, a food science professor at Virginia Tech. Dr. O'Keefe originally helped us answer questions on Why Doesn't Fast Food Spoil? Below, Dr. O'Keefe has much to say about the episode and its inaccuracies.

Have you heard the theory that placing an onion next to your bed will keep you from getting the flu? Are you curious if onions absorb bacteria? Do onions help combat the flu? Will an onion turn black after attracting all of the bacteria? Do onions have powerful antibacterial, antiseptic properties?
We stumbled upon a Facebook post about onions curing the flu, and wondered many of the same questions. We had to find out if it was true, so we reached out to Ruth MacDonald, PhD, RD, Chair and Professor of the Department of Food Science & Human Nutrition at Iowa State University.
We're all looking for a cure for a cold and what better to fight it than a nice hot bowl of chicken soup? But will it really fight off what ails you? We wanted to get to the bottom of the age-old question to understand whether chicken soup really cures a cold. To help decide whether chicken soup is the go-to solution, we reached out to Wendy Dahl, PhD, RD, FDC, Assistant Professor of Food Science and Human Nutrition, at the University of Florida.
Best Food Facts wanted to know, is food coloring safe? To answer this question, we reached out to Dr. Ronald E. Kleinman from Harvard Medical School. When we asked him whether we should avoid food coloring, he said no... but that doesn't mean further research isn't warranted.
Are you concerned about food prices? Last year, we looked at how drought affects food prices, and unfortunately, many parts of the United States are still experiencing drought conditions. On average, Americans spend about 10 percent of their income on food, according to the Bureau of Labor Statistics. But what affects food prices each year? To answer this question, Best Food Facts reached out to Dr. Marc F. Bellemare, Assistant Professor, Sanford School of Public Policy, Duke University.
What do you know about the additives in your food? Particularly, those mysterious ingredients on the label that have us all scratching our heads and wondering “Is this stuff good for me and my family?” Food experts explore whether we should avoid foods with ingredients we cannot pronounce.

Through our five-part series on genetically modified foods and GMOs, something we heard a lot about is the consumers’ right-to-know what’s in their food. We think that knowing more about food is a good thing. When our readers and viewers mentioned genetically modified foods should be labeled, that got us to thinking: “What does the perfect food label look like?”
Recently, Best Food Facts received a question from a reader asking, "Is stevia leaf powder better for us than regular sugar, and would it be better than regular sugar or artificial sweeteners if used by a diabetic or hypoglycemic person?”
A recent study published in Environmental Health Journal assessed the risks to children from the cumulative exposure to chemicals and pesticides in a variety of foods. The study claims that cancer and non-cancer benchmarks were frequently exceeded by children for several food contaminants. Based on the study’s findings, the researchers suggested that new dietary guidelines be developed to minimize exposure to these contaminants.

A leading European environmentalist, Mark Lynas, has apologized to the scientific community. He says he was wrong. After working for years to discredit the work of scientists responsible for genetically-engineered plants and being a contributor to the anti-GM movement, he has come to the conclusion that, "I was completely wrong to oppose GMOs." Why the change? He says, "I discovered science."
