The latest dietary guidelines from the US have flipped the food pyramid—literally and figuratively—sparking a heated debate that goes far beyond what’s on your plate. But here’s where it gets controversial: while protein, dairy, and healthy fats now take center stage, the process behind these changes has raised eyebrows, with accusations of industry influence and questionable science. Could this be a recipe for confusion rather than clarity?*
When the Dietary Guidelines for Americans were unveiled in January, the upside-down food pyramid on the cover (https://cdn.realfood.gov/DGA.pdf) stole the spotlight. But behind the scenes, the health sector is digging into the details—and not everyone is convinced. Long-time food and health journalist Niki Bezzant explains, ‘The process for creating these guidelines is usually rigorous, taking years of research and deliberation.’ Yet, this time, nearly half of the recommendations from the Dietary Guidelines Advisory Committee were rejected, and a new committee—with ties to the beef, dairy, and protein supplement industries—stepped in to rewrite them. ‘It’s unclear how they arrived at these conclusions,’ Bezzant notes, ‘especially when their justifications seem to fall short of gold-standard science.’
And this is the part most people miss: Critics, including the Center for Science in the Public Interest (https://www.cspi.org/statement/new-dietary-guidelines-undercut-science-and-sow-confusion), The Journal of the American Medical Association (https://jamanetwork.com/journals/jama/article-abstract/2844638), and the Physicians Committee for Responsible Medicine (https://www.pcrm.org/news/news-releases/new-dietary-guidelines-were-written-authors-strong-ties-food-industry-doctors), have slammed the guidelines for undermining scientific consensus. In today’s episode of The Detail, Bezzant and dietician Caryn Zinn dissect the changes, the process, and what it means for New Zealand. ‘The biggest problem is that people might dismiss these guidelines as meaningless,’ Zinn warns, ‘and that’s a missed opportunity.’
The new pyramid places protein, dairy, healthy fats, vegetables, and fruits at the base—now the widest part of the triangle—while whole grains are relegated to the top. Sugars? They’ve vanished entirely. ‘Flipping the pyramid visually has added to the confusion,’ Zinn admits, though she believes the changes themselves are largely positive. Highlights include a focus on whole, real foods over ultra-processed options, a strong stance against added sugars, and a boost in recommended protein intake, particularly animal-based sources. Fat is back too, with butter, olive oil, and full-fat dairy getting the green light.
But here’s the kicker: The guidelines suggest limiting saturated fats to 10% of daily calories, yet Zinn argues it’s ‘highly unlikely’ to achieve this while following the recommended intake of fatty meats, oils, and butter. ‘This is a hotly debated topic,’ she adds, pointing to the ongoing controversy over saturated fat and heart disease.
So, how much do these guidelines really matter? In the US, they shape policies in schools and care homes, but their influence here in New Zealand is less direct. Still, Bezzant warns, ‘These messages are everywhere on social media, and they can shape attitudes and behaviors.’ The irony? Most people don’t follow official guidelines anyway. ‘Less than 10% of New Zealanders eat the recommended five to six servings of vegetables daily,’ she notes.
The real danger, according to Bezzant, is oversimplification. ‘The takeaway message seems to be, ‘Eat more steak and butter, woohoo!’ But if people keep consuming refined grains, high-fat, high-sugar, and high-salt diets, no one’s health will improve.’
