Dairy has long been part of a healthy diet, but recent research is highlighting how it fits into today’s wellness goals. As more people look beyond basic nutrition toward foods that support how they feel and function, science is showing dairy’s role is bigger than once thought. National Dairy Council (NDC) conducts and disseminates farmer-funded research helping to ensure that dairy remains part of the modern health conversation.
“There’s a dairy food for everybody,” says Dr. Chris Cifelli, senior vice president of nutrition research at NDC. “It’s not just something that builds strong bones. Its unique package of vitamins, minerals, proteins and bioactive compounds support everything from the gut to the brain.”
Founded in 1915 through the vision of dairy farmers, NDC has spent more than 110 years funding research on how dairy affects health. While traditional focus areas like bone, musculoskeletal health, cardiovascular health and type 2 diabetes remain important, the NDC nutrition research team has leveraged consumer insights to expand into new health and wellness spaces such as energy, mood, sleep, gut health, and more. These areas are shaping how people think about food and what they’re choosing to put in their shopping carts.
Familiar Foods Are Back
Consumers are returning to familiar, recognizable foods, often with a nostalgic nod, and it’s not just about taste. In a world full of options and confusing health claims, people crave simplicity and trust.
“You’re seeing a return to natural foods your grandmother would eat,” Cifelli explains. “Butter, cheese and whole milk are seeing renewed interest.”
Science is reinforcing this shift in perception. Research continues to show how dairy fits into a wide range of healthy eating patterns, including whole milk products that were once misunderstood. As consumers look for foods that feel both familiar and functional, dairy is standing out as a nutrient-dense option that can support everything from daily nourishment to more specific health goals without asking people to choose between comfort and wellness.
Protein for Today
Protein remains one of the most talked-about nutrients, especially as GLP-1 weight-loss medications reshape how people approach appetite and weight management. While these drugs are effective, they can also lead to muscle and bone loss if people don’t eat properly.
“When you lose weight, especially rapidly, your body doesn’t discriminate between fat and muscle,” Cifelli explains. “If you don’t eat well, you’ll lose both. If you’re not eating properly, you can also start to lose bone density.”
Several research studies have shown that diets including three servings of milk, cheese, and yogurt per day help protect lean muscle mass and bone during weight loss.
“Studies have shown that when people eat the recommended three servings of dairy foods each day during weight loss, they are able to maintain lean muscle mass and keep their bones strong,” Cifelli says. “That’s critical because rapid weight loss often means losing muscle and bone along with fat, and dairy helps prevent that.”
That makes dairy, with its high-quality protein and bone-supporting nutrients, a natural fit in the age of weight loss medications.
“As people are on these medications, as they’re trying to achieve the weight they want, dairy is a natural option, especially the higher protein options that will help maintain that lean muscle and bone mass,” he adds.
High-protein yogurts and dairy drinks offer a compact way to deliver protein and essential nutrients, particularly for people eating less overall.
“You’re not eating much, so it can be easy to drink a drinkable yogurt or ultrafiltered milk and feel satisfied,” Cifelli says.
He adds that protein isn’t just a fad, it is a fundamental part of everyday health. Dairy makes meeting those nutritional goals simple and practical. With options like yogurt, cheese, milk, and powders, dairy delivers protein in a way that fits real life.
Fiber and Gut Health for Tomorrow
If protein is today’s hero, gut health could be tomorrow’s. According to Cifelli, the gut contains the most immune cells in the body and forms a direct connection to the brain via the vagus nerve, allowing it to impact everything from mood and anxiety toskin and immunity.
For decades, doctors have urged Americans to eat more fiber for digestive regularity and long-term health. What’s different now is how scientists view the gut itself.
“We used to think of the gut as just the organ that broke down our food and absorbed it,” Cifelli says. “Over the past 20-plus years, we’ve unraveled the importance of the microbiota within the gut and now know that it is like a whole other organ.”
Fermented dairy foods such as yogurt, kefir and many cheeses can help support a healthy microbiota and maintain the gut barrier. At the same time, consumer interest in fiber continues to grow, as fiber acts as fuel for beneficial gut bacteria.
“There are two primary ways to alter and support the gut microbiota,” Cifelli explains. “Fiber, which acts like fertilizer for beneficial bacteria, and live, active cultures from fermented foods.”
Research shows both high-fiber diets and fermented foods improve gut health in different ways. The next step is combining the two, which has led to products like fiber-containing, high-protein yogurts. For consumers, that means convenient foods that support gut health, deliver protein and provide key vitamins and minerals in a familiar dairy format.
Could Wearable Tech Shape Dairy’s Next Role in Health?
While protein, fiber and gut health are driving today’s wellness conversation, Cifelli believes the next big shift could come from something far outside the dairy case: wearable technology.
As smart rings, watches and continuous glucose monitors become more sophisticated, consumers are gaining real-time feedback on blood pressure, blood sugar, sleep, stress and recovery. That constant stream of data will increasingly guide what they choose to eat.
“Our ability to have real-time information on our blood pressure, our glucose, our sleep habits — that’s going to impact what consumers put in their grocery carts,” Cifelli explains.
The goal, he says, is simple: When a device flags a blood sugar spike, poor recovery or lack of quality sleep, dairy, because of its nutrient density and health benefits, should be one of the recommended solutions.
From Science to Grocery Cart
For NDC, funding high-quality research is only half the mission. Conducting research is important but making sure it reaches consumers is just as crucial.
“High-quality research does nobody any good if it only sits on a library shelf,” Cifelli says.
That’s why NDC shares findings through scientific publications, conferences, and industry events. In addition, the dairy checkoff is developing tools that can help brands and companies communicate the science-backed health and wellness benefits of dairy in new and compelling ways.
In a world where shoppers seek foods that support better sleep, focus, mood and overall wellness, dairy foods and ingredients continue to evolve to meet these needs. From protein today to fiber and gut health tomorrow, milk, yogurt and cheese are positioning themselves as versatile, modern allies for health.
“What’s exciting is that there’s a dairy food for everybody, no matter their age or wellness goals,” Cifelli says. “And we’re excited to continue to advance the science on dairy foods to meet the new, emerging health goals of the future.”
