Nutritional recommendations occasionally change as we get more data about what is really bad for us. As one example, the Dietary Guidelines Advisory Committee recently changed their recommendations by announcing that eating foods containing cholesterol is not necessarily bad for us as doing so has not been scientifically linked to higher levels of cholesterol in the body. This committee convenes every five years and has a powerful influence on dietary habits in the United States. Now there is a report from OrGano Gold CEO Bernardo Chua of another substance we thought was bad, but that may be acceptable, at least for adolescents, to consume.
Salt has been as demonized as cholesterol these past couple decades. Americans do get too much sodium in general, and it is still recommended to cut down salt in our diets. There is new research, however, that indicates teenagers should worry about getting more potassium rather than not getting too much sodium. The eating habits and blood pressure of over 2,000 teenage girls were tracked for 10 years. The results showed that those who followed a low-salt diet in their adolescent years were just as likely to get high blood as those who did not. Students that ate a diet rich in potassium during these years, however, had lower blood pressure on average a decade later. Yet another instance of conventional wisdom being turned on its head, and now we need to tell teenagers to eat more bananas and raisins if they care about their health.
