Plant milk is a category of non-dairy beverages made from a water-based plant extract for flavoring and aroma. [1] [2] Nut milk is a subcategory made from nuts, while other plant milks may be created from grains, pseudocereals, legumes, seeds or coconut. Plant-based milks are consumed as alternatives to dairy milk and provide similar qualities, such as a creamy mouthfeel, [3] as well as a bland or palatable taste. Many are sweetened or flavored (e.g., vanilla).
As of 2021, there were about 17 different types of plant milks, of which almond, oat, soy, coconut and pea are the highest-selling worldwide. [4] [5] Production of plant milks—particularly soy, oat, and pea milks—can offer environmental advantages over animal milks in terms of greenhouse gas emissions and land and water use. [6]
Plant-based beverages have been consumed for centuries, with the term "milk-like plant juices" used since the 13th century. In the 21st century, one of these drinks is commonly referred to as a plant-based milk, alternative milk, non-dairy milk or vegan milk. For commerce, plant-based beverages are typically packaged in containers similar and competitive to those used for dairy milk, but cannot be labeled as "milk" within the European Union. [7]
Across various cultures, plant milk has been both a beverage and a flavor ingredient in sweet and savory dishes (such as the use of coconut milk in curries). These drinks are compatible with vegetarian and vegan lifestyles. Plant milks are also used to make ice cream alternatives, plant cream, vegan cheese, and yogurt-analogues (such as soy yogurt). [8] The global plant milk market was estimated to reach US$62 billion by 2030. [5]
Before commercial production of 'milks' from legumes, beans and nuts, plant-based mixtures resembling milk have existed for centuries. [9] The Wabanaki and other Native American tribal nations in the northeastern United States made milk and infant formula from nuts. [10]
In English, the word "milk" has been used to refer to "milk-like plant juices" since 1200 CE. [11]
Recipes from the 13th-century Levant exist describing almond milk. [12] Soy was a plant milk used in China during the 14th century. [3] [13] In medieval England, almond milk was used in dishes such as ris alkere (a type of rice pudding) [14] and appears in the recipe collection The Forme of Cury . [15] Coconut milk (and coconut cream) are traditional ingredients in many cuisines such as in South and Southeast Asia, and are often used in curries. [16]
Plant milks may be regarded as milk substitutes in Western countries, but have traditionally been consumed in other parts of the world, especially ones where there are higher rates of lactose intolerance [2] (see especially Lactose intolerance § Epidemiology).
Common plant milks are almond milk, coconut milk, rice milk, and soy milk. Other plant milks include hemp milk, oat milk, pea milk, and peanut milk. [2] [17] [18]
Plant milks can be made from:
A blend is a plant milk created by mixing two or more types together. Examples of blends are almond-coconut milk and almond-cashew milk.

Although there are variations in the manufacturing of plant milks according to the starting plant material, as an example, the general technique for soy milk involves several steps, including: [2] [3] [20]
The actual content of the highlighted plant in commercial plant milks may be only around 2%. [3] Other ingredients commonly added to plant milks during manufacturing include guar gum, xanthan gum, or sunflower lecithin for texture and mouthfeel, select micronutrients (such as calcium, B vitamins, and vitamin D), salt, and natural or artificial ingredients—such as flavours characteristic of the featured plant—for aroma, color, and taste. [2] [3] [20] [17] Plant milks are also used to make ice cream, plant cream, vegan cheese, and yogurt-analogues, such as soy yogurt.
The production of almond-based dairy substitutes has been criticized on environmental grounds as large amounts of water and pesticides are used. [6] [21] [22] The emissions, land, and water footprints of plant milks vary, due to differences in crop water needs, farming practices, region of production, production processes, and transportation. [19] Production of plant-based milks, particularly soy and oat milks, can offer environmental advantages over animal milks in terms of greenhouse gas emissions, land and water use. [6]
Many plant milks aim to contain the same proteins, vitamins and lipids as those produced by lactating mammals. [9] Generally, because plant milks are manufactured using processed extracts of the starting plant, plant milks are lower in nutrient density than dairy milk and are fortified during manufacturing to add precise levels of micronutrients, commonly calcium and vitamins A and D. [3] [17] [18] Animal milks are also commonly fortified, and many countries have laws mandating fortification of milk products with certain nutrients, commonly vitamins A and D. [23]

Plant-based milks have emerged as an alternative to dairy in response to consumer dietary requests and changing attitudes about animals and the environment. [9] [29] Huffington Post stated that due to health and environmental reasons as well as changing consumer trends, more individuals regularly buy non-dairy alternatives to milk. [30] Between 1974 and 2020, dairy milk consumption of people aged between 16 and 24 in the United Kingdom decreased from 94% to 73%. [29] In Australia, there is decreased confidence within the dairy industry, with only 53% being optimistic in the future profitability and demand for dairy products per a Dairy Australia report. [31]
To improve competition, plant milks are typically packaged in containers similar to those of dairy milks. [1] [32] [33] A scientific journal article argued that plant-milk companies send the message that plant milks are 'good and wholesome' and dairy milk is 'bad for the environment', and the article also reported that an increasing number of young people associate dairy with environmental damage. [29] There has been an increased concern that dairy production has adverse effects on biodiversity, water and land use. [29] These negative links between dairy and the environment have also been communicated through audiovisual material against dairy production, such as 'Cowspiracy' and 'What the Health'. [29] Animal welfare concerns have also contributed to the declining popularity of dairy milk in many Western countries. [29] Advertising for plant milks may also contrast the intensive farming effort to produce dairy milk with the relative ease of harvesting plant sources, such as oats, rice or soybeans. [3] [34] In 2021, an advertisement for oat milk brand Oatly aired during the Super Bowl. [35]
In the United States, plant milk sales grew steadily by 61% over the period 2012 to 2018. [36] As of 2019, the plant-based milk industry in the US is worth $1.8 billion per year. [9] In 2018, the value of 'dairy alternatives' around the world was said to be $8 billion. [37] Among plant milks, almond (64% market share), soy (13% market share), and coconut (12% market share) were category leaders in the United States during 2018. [36] Oat milk sales increased by 250% in Canada during 2019, [38] and its growing consumption in the United States and United Kingdom led to production shortages from unprecedented consumer demand. [39] [40] In 2020, one major coffee retailer – Starbucks – added oat milk, coconut milk, and almond milk beverages to its menus in the United States and Canada. [41] During 2020, oat milk sales in the United States increased to $213 million, becoming the second most consumed plant milk after almond milk ($1.5 billion in 2020 sales). [42]
A key dietary reason for the increase in popularity of plant-based milks is lactose intolerance. For example, the most common food causing intolerance in Australia is lactose and affects 4.5% of the population. [43] In the United States, around 40 million people are lactose intolerant. [44]
Historically, a number of plant-based beverages have been traditionally referred to as "milk". One of the first reliable modern English dictionaries, Samuel Johnson's 1755 A Dictionary of the English Language , gave two definitions of the word "milk". The first described "the liquor with which animals feed their young from the breast", and the second an "emulsion made by contusion of seeds", using almond milk as an example. [45]
In the late 20th and early 21st centuries, the use of the term "milk" for plant-based drinks became controversial. As demand for plant-based milks increased, dairy manufacturers and distributors advocated for legally restricting the term to animal products only: arguing that consumers may confuse the two, or be misled as to the nutritional content of plant-based alternatives. [46]
Many jurisdictions strictly regulate the use of the term "milk" on food labelling. Some countries have outright banned its use for non-dairy products, while others mandate that "milk" only be used with qualifiers (such as "oat milk") on non-dairy alternatives. Where use of the term "milk" is restricted, plant milks may be labeled with terms reflecting their composition (such as "oat drink"), or absence of ingredients (such as "dairy-free"). [3]
Food standards in Australia and New Zealand are developed by the same common body, called Food Standards Australia New Zealand. As of 2024, products sold as 'milk' without qualifiers in Australia or New Zealand "must be milk" which is defined as an animal product. [47] Qualifiers such as "soy milk" are allowed, due to the use of quotation marks in the legislative instrument. [48] [49]
The Canadian Food Inspection Agency limits the use of the word "milk" solely to ″the normal lacteal secretion, free from colostrum, obtained from the mammary gland of an animal″. [50] [51]
In December 2013, European Union regulations stated that the terms "milk", "butter", "cheese", "cream" and "yoghurt" can be used to market and advertise products derived only from animal milk, with a small number of exceptions, including coconut milk, peanut butter and ice cream. [52] In 2017, the Landgericht Trier (Trier regional court), Germany, asked the Court of Justice of the European Union, to clarify European food-labeling law (Case C-422/16), [53] with the court stating that plant-based products cannot be marketed as milk, cream, butter, cheese or yoghurt within the European Union because these are reserved for animal products; exceptions to this do not include tofu and soy. Although plant-based dairy alternatives are not allowed to be called "milk", "cheese" and the like, they are allowed to be described as buttery or creamy. [54] However, there are exceptions for each of the EU languages, based on established use of livestock terms for non-livestock products. The list's extent varies widely; for example there is only one exception in Polish, and 20 exceptions in English. [55]
A proposal for further restrictions failed at second reading in the European Parliament, in May 2021. The proposal, called Amendment 171, would have outlawed labels including 'yogurt-style' and 'cheese alternative'. [56] [57] [58]
In the United Kingdom, strict standards are applied via acts of parliament to food labeling for terms such as milk, cheese, cream, yogurt, which are protected to describe dairy products and may not be used to describe non-dairy produce. These rules date from the United Kingdom's membership of the European Union, and are still in force in Great Britain. [59] [60] To contrast, as of September 2023, the EU Regulation (EU) No 1169/2011 applies directly to Northern Ireland. [59]
The FSSAI stipulates products need a declaration with the phrase "non-dairy product" if the product is a 'plant based beverage', and these must not be labelled with any dairy term. The use of the word 'milk' is limited to animal products. The regulator makes exceptions for cases where, internationally, as in the case of coconut milk and peanut butter, dairy terms were already in-use traditionally. [61] [62] [63] [64]
In the United States, the dairy industry petitioned the FDA to ban the use of terms like "milk", "cheese", "cream" and "butter" on plant-based analogues (except for peanut butter). [65] FDA commissioner Scott Gottlieb stated on July 17, 2018, that the term "milk" is used imprecisely in the labeling of non-dairy beverages, such as soy milk, oat milk and almond milk: "An almond doesn't lactate", he said. [1] In 2019, the US National Milk Producers Federation petitioned the FDA to restrict labeling of plant-based milks, claiming they should be described as "imitation". [66] In response, the Plant-Based Foods Association stated the word "imitation" was disparaging, and there was no evidence that consumers were misled or confused about plant-based milks. [66] A 2018 survey by the International Food Information Council Foundation found that consumers in the United States do not typically confuse plant-based analogues with animal milk or dairy products. [65] [67] As of 2021, though the USDA is investigating and various state legislatures are considering regulation, various courts have determined that reasonable consumers are not confused, and the FDA has enacted no regulations against plant-based milk labels. [46]
In 2021, the FDA issued a final rule that amends yogurt's standard of identity (which remains a product of "milk-derived ingredients"), and was expected to issue industry guidance on "Labeling of Plant-based Milk Alternatives" in 2022.[ needs update ] [68] [69]
Proponents of plant-based milk assert that these labeling requirements are infantilizing to consumers [70] and burdensome and unfair on dairy-alternatives. [71] Critics of the FDA's labeling requirements also asserted that there is often collusion between government officials and the dairy industry in an attempt to maintain dairy dominance in the market. [72] [73] For example, in 2017, Sen. Tammy Baldwin of Wisconsin introduced the "Defending Against Imitations and Replacements of Yogurt, Milk, and Cheese to Promote Regular Intake of Dairy Everyday (DAIRY PRIDE) Act" which would prevent almond milk, coconut milk and cashew milk from being labeled with terms like "milk", "yogurt", and "cheese". [74] Proponents of plant-based dairy alternatives argued that dairy sales are decreasing faster than plant sales are increasing and that therefore, attacking plant milks as being the chief reason for a decline in dairy consumption is inaccurate. A 2020 USDA study found that the "increase in sales over 2013 to 2017 of plant-based options is one-fifth the size of the decrease in Americans' purchases of cow's milk." [75]
Health authorities recommend that plant milks should not be given to infants younger than 12 months unless commercially prepared infant formula is available, such as soy infant formula. [76] A 2020 clinical review stated that only appropriate commercial infant formulas should be used as alternatives to human milk which contains a substantial source of calcium, vitamin D and protein in the first year of life and that plant milks "do not represent an equivalent source of such nutrients". [77]
The Healthy Drinks, Healthy Kids 2023 guidelines state that infants younger than 12 months should not drink plant milks. [78] They suggest that children between 12 and 24 months may consume fortified soy milk, but not other non-dairy milks such as almond, oat and rice, which are deficient in key nutrients. [78] A 2022 review suggested that the best option for toddlers (1–3 years old) who do not consume cow's milk would be to have at least 250 mL/day of fortified soy milk. [79]
For vegan infants younger than 12 months who are not breastfed, the New Zealand Ministry of Health recommends soy infant formula and advises against the use of plant milks. [80] A 2019 Consensus Statement from the Academy of Nutrition and Dietetics, American Academy of Pediatric Dentistry, American Academy of Pediatrics, and the American Heart Association concluded that plant milks are not recommended for infants younger than 12 months and that for children aged 1–5 years plant milks may be useful for those with allergies or intolerances to cow's milk but should only be consumed after a consultation with a professional health care provider. [81]
Vegetarian cuisine is based on food that meets vegetarian standards by not including meat and animal tissue products.
Yogurt is a food produced by bacterial fermentation of milk. Fermentation of sugars in the milk by these bacteria produces lactic acid, which acts on milk protein to give yogurt its texture and characteristic tart flavor. Cow's milk is most commonly used to make yogurt. Milk from water buffalo, goats, ewes, mares, camels, and yaks is also used to produce yogurt. The milk used may be homogenized or not. It may be pasteurized or raw. Each type of milk produces substantially different results.
Soy milk, also known as soya milk or soymilk, is a plant-based drink produced by soaking and grinding soybeans, boiling the mixture, and filtering out remaining particulates. It is a stable emulsion of oil, water, and protein. Its original form is an intermediate product of the manufacture of tofu. Originating in China, it became a common beverage in Europe and North America in the latter half of the 20th century, especially as production techniques were developed to give it a taste and consistency more closely resembling that of dairy milk. Soy milk may be used as a substitute for dairy milk by individuals who are vegan or lactose intolerant.
Rice milk is a plant milk made from rice. Commercial rice milk is typically manufactured using brown rice and brown rice syrup, and may be sweetened using sugar or sugar substitutes, and flavored by common ingredients, such as vanilla. It is commonly fortified with protein and micronutrients, such as vitamin B12, calcium, iron, or vitamin D.
Almond milk is a plant-based milk substitute with a watery texture and nutty flavor manufactured from almonds, although some types or brands are flavored in imitation of cow's milk. It does not contain cholesterol or lactose and is low in saturated fat. Almond milk is often consumed by those who are lactose-intolerant and others, such as vegans, who do not consume dairy products. Commercial almond milk comes in sweetened, unsweetened, vanilla and chocolate flavors, and is usually fortified with micronutrients. It can also be made at home using a blender, almonds and water.
Coconut milk is an opaque, milky-white liquid extracted from the grated pulp of mature coconuts. The opacity and rich taste of coconut milk are due to its high oil content, most of which is saturated fat. Coconut milk is a traditional food ingredient used in Southeast Asia, Oceania, South Asia, and East Africa. It is also used for cooking in the Caribbean, Central America, northern parts of South America and West Africa, where coconuts were introduced during the colonial era.
A milk substitute is any substance that resembles milk and can be used in the same ways as milk. Such substances may be variously known as non-dairy beverage, nut milk, grain milk, legume milk, mock milk and alternative milk.
Peanut milk is a plant milk, which is an alternative to animal milk. It is made with peanuts, water, and sometimes other additional ingredients like salt, sugar, or cinnamon. Peanut milk is high in fat and protein compared to other plant-based milks. This milk is sometimes used by people who identify with lactose intolerance, veganism, or a casein-free diet, as it has no lactose, but includes nutritional benefits like being high in magnesium, Vitamin E, Vitamin B-6, and protein.
Silk is an American brand of dairy-substitute products currently owned by Danone after it purchased WhiteWave Foods in 2016.
Oat milk is a plant milk derived from whole oat grains by extracting the plant material with water. Oat milk has a creamy texture and mild oatmeal-like flavor, and is manufactured in various flavors, such as sweetened, unsweetened, vanilla, and chocolate.
Alpro is a European company based in Ghent, Belgium, that markets organic and non-organic, non-genetically modified, plant-based products, such as foods and drinks made from soy, almonds, hazelnuts, cashew, rice, oats or coconut. Alpro employs over 1,200 people in Europe and has three production facilities in Belgium, France and the United Kingdom. Alpro markets its products in Europe and beyond with the majority of its business in Europe.
Soy yogurt, also referred to as soya yogurt, soygurt or yofu, is a yogurt-like product made with soy milk.
SmithFoods is a regional maker of dairy products, beverages, and ice cream headquartered in Orrville, Ohio. The company sells products under two major brands, Smith's and Ruggles, as well as private label brands, for both retail and wholesale distribution.
Plant cream is an imitation of dairy cream made without dairy products, and thus vegan. It is typically produced by grinding plant material into a thick liquid to which gums are added to imitate the viscosity and mouthfeel of cream. Common varieties are soy cream, coconut cream, and cashew cream. It is used as a dessert topping and in many other dishes and beverages.
Plamil Foods Is a British manufacturer of vegan food products. Founded in 1965, the company has produced and pioneered soy milk, egg-free mayonnaise, pea-based milk, yogurts, confection bars and chocolate.
Vegan cheese is a category of non-dairy, plant-based cheese analogues. Vegan cheeses range from soft fresh cheeses to aged and cultured hard grateable cheeses like plant-based Parmesan. The defining characteristic of vegan cheese is the exclusion of all animal products.
Ripple Foods is a California-based brand of pea-protein dairy alternative products. The company was founded in 2014 by Adam Lowry and Neil Renninger in Emeryville, California.
Pea milk is a type of plant milk. It is made using pea protein extracted from yellow peas, usually in combination with water, sunflower oil, micronutrients added for food fortification, thickeners, and phosphates. Commercial pea milk typically comes in sweetened, unsweetened, vanilla and chocolate flavors. It is marketed as a more environmentally-friendly alternative to almond milk and a non-GMO alternative to soy milk. It is a suitable product for people with soy allergies.
Oatly Group AB is a Swedish food company that produces alternatives to dairy products from oats, including oat milk. Oatly was formed in the 1990s using research from Lund University. Oatly has headquarters in Malmö and a production and development center in Landskrona.
The context within which foods such as soy milk or soy ice cream are sold is indicated by use of the name soy; indicating that the product is not a dairy product to which a dairy standard applies.
