Milk is a commonly used beverage that is necessary in the diets of many millions of people across the globe because it contains vital macro- and micronutrients. Because of its composition, milk is regarded as beneficial throughout infancy and adolescence; nevertheless, its relatively high saturated fat content raises concerns about possible negative consequences, particularly on the cardiovascular system. The most current research on dairy and human health is evaluated in this review, which is framed by epidemiologic, experimental, and biochemical data. The effects of milk (particularly skimmed milk) on body weight, for example, seem to be well established, and the overwhelming majority of published research conclude that dairy intake does not raise cardiovascular risk or the prevalence of certain malignancies. Despite the lack of convincing data, several research indicate that milk and its derivatives may be advantageous to some demographic groups. Although further research on the role of milk and dairy products in human health is needed, their inclusion in a balanced diet should be explored unless there are obvious contraindications
