Dairy products or milk products are a type of food produced from or containing the milk of mammals, primarily cattle, water buffaloes, goats, sheep, and camels. Dairy products include food items such as yogurt, cheese, and butter. A facility that produces dairy products is known as a dairy, or dairy factory. Dairy products are consumed worldwide, with the exception of much of East and Southeast Asia and also some parts of central Africa.
Dairy products can cause some issues for individuals who have lactose intolerance or a milk allergy.
Additionally dairy products can contribute significant amounts of cholesterol and saturated fat to the diet which can increase the risk of heart disease, and cause other serious health problems. However, it has been shown that there is no connection between dairy consumption (excluding butter) and cardiovascular disease, even though dairy tends to be higher in saturated fats.
There is no excess cardiovascular risk with dietary calcium intake but calcium supplements are associated with a higher risk of coronary artery calcification.
Drinking milk or other dairy products does not cause mucus production, and will not make cold or asthma symptoms worse. This widely held belief stems from some people mistaking the thin coat of residue left behind after consuming milk or ice cream for mucus.
Rates of dairy consumption vary widely worldwide. High-consumption countries consume more than 150 kg per capita per year: Argentina, Armenia, Australia, Costa Rica, Europe, Israel, Kyrgyzstan, North America and Pakistan. Medium-consumption countries consume 30 to 150 kg per capita per year: India, Iran, Japan, Kenya, Mexico, Mongolia, New Zealand, North and Southern Africa, most of the Middle East, and most of Latin America and the Caribbean. Low-consumption countries consume under 30 kg per capita per year: Senegal, most of Central Africa, and most of East and Southeast Asia.
