Nutritional Pyramid what should you really eat?We can’t look at a nutritional pyramid these days without thinking of food and healthy eating. There was the U.S. government’s Food Guide nutritional pyramid, followed by its replacement, My nutritional pyramid, which was basically the same thing, just pitched on its side. The problem was that these efforts, while generally good intentioned, have been quite flawed at actually showing people what makes up a healthy diet. Why? Their recommendations have often been based on out-of-date science and influenced by people with business interests in their messages.

But, there’s a better alternative: the Healthy Eating nutritional pyramid, built by the faculty in the Department of Nutrition at the Harvard School of Public Health. Based on the latest science, and unaffected by businesses and organizations with a stake in its messages, the Health Eating nutritional pyramid is a simple, trustworthy guide to choosing a healthy diet. Its foundation is daily exercise and weight control, since these two related elements strongly influence your chances of staying healthy. The Healthy Eating nutritional pyramid builds from there, showing that you should eat more foods from the bottom part of the nutritional pyramid (vegetables, whole grains) and less from the top (red meat, refined grains). |

IntroductionMore than a decade and a half ago, the U.S. Department of Agriculture (USDA) created a powerful and enduring icon: the Food Guide Pyramid. This simple illustration conveyed in a flash what the USDA said were the elements of a healthy diet. The Pyramid was taught in schools, appeared in countless media articles and brochures, and was plastered on cereal boxes and food labels.
Tragically, the information embodied in this pyramid didn't point the way to healthy eating. Why not? Its blueprint was based on shaky scientific evidence, and it barely changed over the years to reflect major advances in our understanding of the connection between diet and health.
With much fanfare, in 2005, the USDA retired the old Food Guide Pyramid and replaced it with MyPyramid, a new symbol and "interactive food guidance system." The new symbol is basically the old Pyramid turned on its side. The good news is that this dismantles and buries the flawed Pyramid. The bad news is that the new symbol doesn't convey enough information to help you make informed choices about your diet and long-term health. And it continues to recommend foods that aren't essential to good health, and may even be detrimental in the quantities included in MyPyramid. As an alternative to the USDA's flawed pyramid, faculty members at the Harvard School of Public Health built the Healthy Eating Pyramid. It resembles the USDA's in shape only. The Healthy Eating Pyramid takes into consideration, and puts into perspective, the wealth of research conducted during the last 15 years that has reshaped the definition of healthy eating. |
