Over the last 40 years, confusion has mounted surrounding what a healthy diet should consist of. Recently, the Trump administration published its version, a new and improved food pyramid which is supposed to demonstrate the optimal diet for the average American. The food pyramid is a visual guide that explains how to maintain a balanced diet, displaying which types of foods are to be eaten more often than others. The most recent food pyramid is illustrated as an upside down triangle, with the foods at the top of the triangle representing those which should be eaten the most often while those at the bottom correspond to the foods that should be consumed the least. However, what the “ideal diet” truly consists of has been subject to much debate, especially in the last few weeks following the recently modified food pyramid.
Taking a look at the history of America’s dietary guidelines gives important context to the recent changes made by the Trump administration. In 1980, the first dietary recommendations were introduced to the public, aimed at reducing the rise in chronic diseases like high blood pressure, diabetes and heart disease. The guidelines advised Americans to “eat a variety of foods” and to stay away from too much sodium and too many fats and sugars. These were vague and broad suggestions, but they aimed to make the country healthier and more nutritionally-educated.
In 1992, the very first food pyramid was created. It labeled carbs such as breads and cereals as the most important part of a healthy diet, recommending six to 11 servings of grains every day. However, over the course of the next decade, nutritionists and medical experts began arguing that six to 11 servings of breads and pastas was far too much and detrimental to our health, leaving the general public confused. In 2011, President Barack Obama introduced “MyPlate,” which displayed vegetables and grains as more important than protein and fruits. However, many critics argued that this “food plate” was far too oversimplified and didn’t give Americans any idea about what is healthy and what is unhealthy.
The Trump administration’s changes, introduced this year by the U.S. Department of Health and Human Services (HHS) and the U.S. Department of Agriculture (USDA), modify the food pyramid by inverting it to look like an upside down triangle. The new pyramid prioritizes healthy fats and proteins and surprisingly downgrades grains. According to White House Press Secretary Karoline Leavitt, these changes are “align[ed] with the President’s promise to make America Healthy Again.” HHS Secretary Robert F. Kennedy Jr. said that the new guidelines are “the most significant reset of federal nutrition policy in history.” The tagline for this new approach is “eat real food.”
The new food pyramid emphasizes caution when consuming ultra-processed foods and refined grains. Recommendations from these new guidelines emphasize the importance of cutting down on sugary drinks, packaged snacks, breads and pastas due to their associated risk of blood sugar spikes, weight gain and other chronic issues. The new guidelines also recommend Americans dramatically step up their protein consumption, to 1.2 to 1.6 grams per kilogram of body weight a day. The previous recommendations called for healthy adults to consume 0.8 grams per kilogram. “This isn’t totally new advice—in some ways it’s status quo—but the food industry should certainly worry because it reinforces the message that what they’re selling is making us sick,” Jerold Mande, an adjunct professor of nutrition at Harvard’s T.H. Chan School of Public Health, told The Wall Street Journal.
Some nutritionists, however, have criticized the new pyramid, arguing that proteins such as beef and other red meats, which are higher in saturated fat, have risks that are being ignored, not to mention that they are more expensive than plant-based alternatives. Many nutritionists believe that plant-based diets are by far the healthiest and that animal-based diets lead to chronic diseases. They argue that the health implications of consuming too much saturated fat are being completely ignored, despite some studies showing that it raises Low-Density Lipoprotein (LDL) cholesterol — the bad kind of cholesterol— and can increase the risk of heart disease. The Trump administration has argued simply that research has given mixed results and that the focus right now is primarily on avoiding ultra-processed foods and refined grains.
It appears that the new food pyramid aims to inform the public of the potential dangers of many of the foods we have become accustomed to consuming. While it seems like America gets new dietary guidelines every 10 years, these changes are not arbitrary. Instead, they reflect advances in nutritional research and a stronger understanding of how various foods can impact our long-term health. As science evolves, so must the recommendations meant to protect public well-being. Ultimately, trusting updated guidelines can allow individuals to take greater control of their health and strive to live longer and healthier lives.
