Milk is an ingredient in many confectioneries. Milk can be added to chocolate to produce milk chocolate.
Rates of dairy consumption vary widely worldwide. High-consumption countries consume more than 150 kilograms (330 lb) per capita per year. These countries are: Argentina, Armenia, Australia, Costa Rica, most European countries, Israel, Kyrgyzstan, Canada, the United States and Pakistan. Medium-consumption countries consume 30 kilograms (66 lb) to 150 kg per capita per year. These countries are: 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. These countries are: Senegal, most of Central Africa, and most of East and Southeast Asia.
There is no scientific evidence that consuming dairy products causes cancer. The British Dietetic Association have described the idea that milk promotes hormone related cancerous tumour growth as a myth, stating "no link between dairy containing diets and risk of cancer or promoting cancer growth as a result of hormones". In 2024, Cancer Research UK stated "there is no reliable evidence that casein or hormones in dairy causes cancer in people". The American Cancer Society (ACS) does not make specific recommendations on dairy food consumption for cancer prevention. Higher-quality research is needed to characterise valid associations between dairy consumption and risk of and/or cancer-related mortality.
Consumption of dairy products such as low-fat and whole milk have been associated with an increased acne risk, however, as of 2022 there is no conclusive evidence. Fermented and low-fat dairy products are associated with a decreased risk of diabetes. Consumption of dairy products are also associated with a decreased risk of gout.
A 2023 review found that higher intake of dairy products is significantly associated with a lower risk of inflammatory bowel disease. A 2025 review found that dairy product intake is associated with a lower incidence of tinnitus.
Some groups avoid dairy products for non-health-related reasons. Some religions restrict or do not allow the consumption of dairy products. For example, some scholars of Jainism advocate not consuming any dairy products because dairy is perceived to involve violence against cows. Orthodox Judaism requires that meat and dairy products not be served at the same meal, served or cooked in the same utensils, or stored together, as prescribed in Deuteronomy 14:21.
Growing awareness of dairy products' environmental impact, specifically greenhouse gas emissions, has led to many people reducing or avoiding dairy. In the EU, dairy is responsible for 27% of all diet related emissions, on average, while plant-based milks cause 2.5–4.5 times fewer emissions.
