Introduction:Plant-based milk has gained widespread popularity due to its eco-friendly and healthy image, becoming almost a staple in the specialty coffee market. However, many consumers may not fully understand the actual nutritional composition of plant-based milk and might even mistakenly believe that all such alternatives are healthier than dairy milk. Recently, the U.S. FDA proposed a new draft guideline requiring plant-based milk packaging to clearly indicate its nutritional differences from dairy milk, helping consumers make more informed choices. This article provides an in-depth analysis of the nutritional comparison between plant-based milk and dairy milk, as well as the potential impact of the new regulations on the market.
In recent years, plant-based milk has surged in popularity due to increased environmental awareness and health-conscious dietary trends, especially in cafés where oat milk has become the preferred choice for many customers. However, some medical experts point out that many consumers opt for plant-based milk not because of lactose intolerance, but due to following popular trends—with limited understanding of its nutritional value.
To address this, the U.S. Food and Drug Administration (FDA) published an industry draft guideline on February 22, requiring plant-based milk to clearly display its nutritional content and provide direct comparisons with dairy milk, to help consumers better understand the actual nutritional value of the products they purchase.
The draft states that although many plant-based milk products claim to be "milk alternatives," their nutritional profiles actually differ significantly from those of dairy milk. For instance, many plant-based milks contain lower levels of vitamin D and calcium compared to dairy milk, and this information should be clearly indicated on the packaging to raise consumer awareness.
According to nutritional standards set by the U.S. Department of Agriculture (USDA), only fortified soy beverages, which have a nutritional structure similar to dairy milk, are considered eligible to be included in the dairy category. As for other common plant-based milks—including almond milk, oat milk, coconut milk, and pea milk—their protein, vitamin, and mineral contents are generally inferior to those of dairy milk.

Experts note that dairy milk is a key source of many important nutrients, such as protein, vitamin A, B-12, as well as calcium, potassium, and vitamin D, which are often under-consumed in modern diets. Therefore, dietary guidelines still consider dairy milk an essential component of a healthy diet.
FDA medical experts further explain that for growing children and adolescents, obtaining adequate and balanced nutrition from dairy milk or fortified soy beverages is particularly crucial. Many parents may not realize that the nutritional profiles of some plant-based milks differ greatly from those of dairy milk, potentially affecting their children’s developmental needs.
Currently, most plant-based milk packaging only lists basic nutritional information such as fat, protein, fiber, and sugar, but rarely specifies the concrete differences compared to dairy milk. Moreover, to achieve better taste and texture, many plant-based milk products are additionally fortified with plant oils or sugars, which could actually increase the risk of obesity and cardiovascular diseases—especially when consumed in large quantities.
It is worth noting that the metabolism of plant oils and fructose differs from that of dairy fat and lactose. Some studies suggest that excessive intake of plant oils may raise levels of bad cholesterol (LDL), thereby impacting cardiovascular health. Therefore, when choosing plant-based milk, consumers should carefully read the nutritional labels and avoid assuming that “lactose-free” automatically means “healthier.”
If the new FDA regulations are officially implemented, they are expected to push plant-based milk manufacturers to disclose product information more transparently and may alter the overly idealized marketing of plant-based milk in the market. For consumers, being able to make suitable choices based on more comprehensive nutritional information is key to improving overall dietary quality.
