Rising levels of carbon dioxide in the atmosphere are making crops grow bigger & faster. However, researchers have found that these crops contain significantly lower levels of protein, iron, zinc, and other important nutrients, potentially endangering nutrition for hundreds of millions of people. Experts explain the effect will get worse as CO2 levels continue to rise, and what might be done to combat the problem.

If medical experts aren’t sure which foods are healthy, how do we decide what to eat? Dr. Charles Katzenberg, a cardiologist at the Sarver Heart Center, says he has discussions about heart healthy food every day with his patients. There is not a national consensus on heart healthy food. This means that different people will give different answers, and no one seems to know what to do. Most cardiologists agree that a good diet will help a person. While the same cardiologists admit to having minimal or no training at all on nutrition in medical school or at their residencies.
Dr. Stephen Devries of the Gaples Institute says while some nutritional knowledge is common sense, other information needs to be taught. If medical professionals aren’t properly trained, they won’t be able to suggest effective interventions. Why is nutrition not taught to a cardiologist? According to Dr. Katzenberg, nutrition isn’t taught to cardiologists, because their training programs prioritize other information.. Both experts agree that the issue starts with the system not putting enough emphasis on preventative measures. The key to solving this problem is for medical professionals to work together with other specialists, like nutritionists, who might have relevant training that would benefit the patient.

The FDA has proposed mandating a significant cut in the nicotine content of cigarettes to encourage them to move to healthier forms of nicotine distribution, such as e-cigarettes. Experts explain how the plan might work and the science behind it.
Do Cardiologists Know Nutrition?
A healthy diet is one of the best weapons against heart disease and its recurrence, yet new studies show cardiologists (as well as other physicians) are woefully deficient in nutritional knowledge. Experts discuss causes and outcomes of this lack of knowledge.
Synopsis: Super Bowl party snacks are prime territory for contamination via cross contamination and being dropped on the floor. A scientist who has studied both phenomena discusses the truth (or lack of truth) in two old myths.

Synopsis: Low-level systemic inflammation is being tied to many disorders including heart disease, and now research has even tied inflammation to intermittent explosive disorder, a syndrome of repeated rage. Experts discuss these findings and how inflammation can be combatted through diet and supplementation.
