Diet is an important modifiable risk factor for obesity. Although it is well-known that excess calories lead to weight gain, diet is beyond just counting calories. In nutrition, diet is the sum of food we consume. What we eat, when we eat, and how we eat all play a role in how our body takes in and uses energy.

“How do you know that spring is coming? Magazines start calling to ask if grilled meat causes cancer.” That was the “joke” we told each other in the National Cancer Institute’s press office – as predictable as the seasons themselves, we’d start getting calls in late winter from writers who wanted to know about the dangers of the backyard barbeque. Their questions were always similar -- do grilled meats cause cancer? How? Was meat healthier if it was cooked a different way? Did the type of meat matter? How much meat is “safe” to eat?
When I was in elementary school, the quintessential school-bought lunch contained a generic deli meat sandwich slathered with mayo, a carton of milk, and a bag of overly salted potato chips. Delicious and loved by nearly every student, the food being served was far from nutritious. The standards for school lunches have drastically changed after the implementation of federal policies, particularly the Healthy, Hunger-Free Kids Act in 2010. This bill provided funding for school meals and child nutrition, promoted overall student wellness, and, perhaps most notably, set very clear standards for making school meals healthier by including key reforms to school meals such as increasing fruits, vegetables, and whole grains.
 Sheryl Rifas-Shiman, MPH In the December 2017 online issue of the Annals of the American Thoracic Society, several colleagues and I reported that children who consumed high amounts of fructose in early childhood or whose mothers drank a lot of sugary beverages while pregnant may be at greater risk for developing asthma in mid-childhood.
 Veronique Gingras, MSc, PhD In August and September 2017, three nutrition studies derived from the PURE study were published in the Lancet and an old, endless – and somewhat tiresome – debate resurfaced: is a low-carbohydrate or a low-fat diet better for your health? These publications received tremendous attention with headlines such as: Study challenges conventional wisdom on fats, fruits and vegetables or PURE shakes up nutritional field: finds high fat intake beneficial. However, many of the headlines either exaggerated or misrepresented the findings. The media coverage that followed highlights how important it is to be cautious when we interpret and present results.
