Role of Dairy in the Diet

Dairy foods and ingredients play an important nutrition delivery and cultural role in the daily diets of people around the world. Whether traditional fare or new additions to regional preferences, dairy foods provide clear benefits to people of all ages. Specifically:

  • Dairy and dairy-containing foods contribute many essential nutrients including protein, calcium, vitamin D, vitamin A, vitamin B12, riboflavin, niacin, phosphorus, potassium and magnesium
  • Milk, cheese and yogurt are core aspects of healthy eating patterns and dietary guidance recommendations in many countries
  • Dairy ingredients like whey and milk proteins support healthful diets and are found in dairy-based beverages, yogurt, nutrition and energy bars, ready-to-drink beverages, oatmeal, snacks and powder for homemade smoothies and shakes

Dairy contributes essential nutrients 

Role of dairyThe Food and Agriculture Organization (FAO) highlights dairy as a way to help people across populations meet the body's needs for calcium, magnesium, selenium, riboflavin, vitamin B12 and pantothenic acid.1  In the United States, milk is the number one food source for calcium, vitamin D and potassium in the diets of adults and children; cheese is the number two food source of calcium, after milk.2,3   

Nutrient-dense dairy foods-milk, cheese and yogurt-are also a core part of healthy eating patterns and dietary guidance recommendations around the world, including the Dietary Approaches to Stop Hypertension (DASH) eating plan,4 heart health-focused eating plans from the American Heart Association5 and diabetes management-focused eating plans from the International Diabetes Federation.6  

Dairy's nutrient-rich package is recognized and recommended across the globe as an important part of well-rounded, healthy diets. Below is a snapshot of international dietary guideline recommendations in select international markets.

 *Note: Daily intake guidelines are country-specific; serving size and measurement may differ by market.


Dairy foods deliver

Health benefits such as the calcium and vitamin D dairy foods provide to growing children are well known. However, dairy foods' health and nutrition benefits extend beyond childhood, and are important to adults of all ages. Research indicates dairy food consumption (including milk, cheese and yogurt): 

  • Benefits overall bone health in adults7
  • May help reduce the risk of high blood pressure in a variety of populations8
  • May help reduce the risk for cardiovascular disease (CVD), coronary heart disease (CHD) and stroke in a variety of populations9
  • Is associated with reduced risk of type 2 diabetes10  

Dairy proteins boost health benefits

Beyond essential nutrient delivery, dairy foods are naturally high in protein and can play an important role in positive health outcomes. Likewise, dairy ingredients like whey and milk proteins can provide a variety of health and wellness benefits when added to products such as ready-to-drink shakes, snack bars and even meals. Research shows higher-protein diets, which can be achieved by adding dairy ingredients, like whey and milk proteins into meals, can help people:

  • Promote muscle repair and recovery after exercise11, 12, 13, 14
  • Maintain a healthy weight15, 16, 17, 18, 19, 20
  • Curb hunger21, 22, 23
  • Build lean muscle (when combined with regular resistance exercise) 24, 25, 26
  • Enhance exercise recovery 11, 12, 13. 14
  • Maintain muscle mass as they age27, 28  

Below are some tips to provide a protein boost to many popular foods using dairy foods and dairy ingredients.

  • Pair yogurt-based dips, sauces and dressings with veggies or fruits for added nutritional boost.
  • Dairy proteins like whey can enrich foods not commonly high in protein like beverages, bars, pastas and baked goods.  
  • Diverse cheese varieties provide nutrients and taste appeal as ingredients in soups, sauces, dips and baked goods.
