Sugar and red meat are the villains du jour when it comes to what we should and should not eat. Today, an important advisory committee issued its recommendations for the USDA food guidelines. The federal government adjusts its food pyramid -- or plate, now -- every five years and is expected to make a final decision later this year. The panel recommends that we pay taxes on sugary drinks and snacks. They also say we should eat less red meat and consider the environment when we decided whether or not to eat a burger. Both recommendations are likely to be fought vigorously by the food industry. We catch up on the food fight.
