the value of 'dairy alternatives' around the world was said to be $8 billion. 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. Oat milk sales increased by 250% in Canada during 2019, and its growing consumption in the United States and United Kingdom led to production shortages from unprecedented consumer demand. 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. 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). A key dietary reason for the increase in popularity of plant-based milks such as pea milks is lactose intolerance. For example, the most common food causing intolerance in Australia is lactose and affects 4.5% of the population. In the United States, around 40 million people are lactose intolerant. Labeling and terminology 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. As plant milks resurged in popularity in the late twentieth and early twenty first centuries, their definition became a matter of controversy. Plant milks may be labeled to highlight their nutrient contents, or with terms reflecting their composition or absence of ingredients, such as "dairy-free", "gluten-free" or "GMO-free". Manufacturers and distributors of animal milk have advocated that plant-based milk not be labelled as "milk". They complain that consumers may be confused between the two, and that plant-based milks are not necessarily as nutritious in terms of vitamins and minerals. Europe In December 2013, European Union regulations stated that the terms "milk", "butter", "cheese", "cream" and "yoghurt" can only be used to market and advertise products derived from animal milk, with a small number of exceptions including coconut milk, peanut butter and ice cream. 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), with the court stating that plant-based products cannot be marketed as milk, cream, butter,
