Plant-based milk market cools as nutrition and labeling questions stay in focus

Plant-based milks—long a major growth engine in dairy alternatives—are showing signs of a slowdown in sales, even as market analysts continue to project expansion for the broader category and researchers and regulators spotlight key differences in nutrition and labeling.

Industry reporting from Dairy Foods pegged plant-based milk sales down 5.4% in recent figures, despite describing the segment as a top driver of dairy-alternative growth alongside vegan cheese. A separate trade analysis from FoodNavigator also reported a cooling market for plant-based milks, framing the shift as dairy “making a comeback.”

Market forecasts still point upward, with lactose intolerance cited as a tailwind

Even with near-term softness in some sales data, multiple market research firms continue to forecast growth in the global plant-based milk segment, citing consumer demand and product innovation.

A Coherent Market Insights update carried by Yahoo Finance projected the plant-based milk market could surpass $35.22 billion by 2032, and pointed to lactose intolerance as a structural driver, referencing estimates that roughly 65% of adults have some degree of lactose malabsorption. Other market reports similarly describe plant-based milk substitutes as a leading contributor to the expansion of dairy alternatives.

Analysts also describe continued investment by major food companies in oat, soy, rice and almond beverages, as well as hybrid dairy-plant blends, reflecting ongoing competition for consumers seeking milk-like products across price points and use cases (from cereal to coffee).

Nutrition research highlights that “milk alternatives” are not nutritionally interchangeable

Alongside market shifts, researchers have continued to emphasize that plant-based milks vary widely in protein, micronutrients and fortification practices, and that nutritional equivalence to dairy is not guaranteed.

A 2024 systematic review and meta-analysis of randomized trials in BMC Medicine evaluated outcomes when soymilk substitutes for cow’s milk in controlled settings, examining intermediate cardiometabolic markers. The analysis adds to evidence that the health impact of swapping dairy for a plant-based alternative depends heavily on the specific product and its nutrient profile—particularly because many non-dairy beverages differ substantially from cow’s milk in protein and certain vitamins and minerals.

Broader peer-reviewed reviews have also underscored that plant-based milk alternatives are typically produced by homogenizing plant materials with water and then stabilizing the mixture, which can yield beverages that mimic milk’s texture but not its macronutrient balance. Review authors have called for more standardized comparative research across product types—such as pea, coconut and cashew—especially when considering multiple outcomes at once.

Institutional guidance emphasizes fortification and consumer clarity

Public-sector and institutional guidance has focused on two key issues: nutrient adequacy (especially for products used as a primary milk replacement) and clear labeling that helps consumers understand what they are buying.

An extension publication from the University of Kentucky noted that dietary guidance commonly encourages cow’s milk or fortified soy milk for people over age 1 due to nutrient profile considerations, and described soy milk as the closest match among common plant-based options when cow’s milk is not tolerated.

At the federal level, the U.S. Food and Drug Administration has continued to work on how plant-based products are named and described. The agency’s draft guidance on labeling of plant-based milk alternatives describes consumer research efforts—such as focus groups—intended to assess how shoppers interpret product names and whether they understand nutritional differences compared with dairy milk. The FDA has also published consumer-facing information discussing the expanding market of plant-based alternatives and the importance of understanding product composition and nutrient content.

What happens next

With plant-based milk sales showing some weakness in parts of the market, analysts are watching whether product reformulations, fortification strategies, and clearer labeling can support renewed growth—particularly as dairy competes on price, familiarity and nutrition messaging.

Meanwhile, the research consensus remains that “plant-based milk” is not a single nutritional category, and that the health implications of substituting a non-dairy beverage for cow’s milk depend on the specific product—especially protein content and fortification.
