A June 2021 study by the University of South Australia said,
"People have long had a love-hate relationship with milk, which is not surprising given the mixed messages about dairy,”
"While some reports show that high dairy and milk consumption is linked with cardio-metabolic risk factors, evidence from randomised controlled trials have been inconsistent.
"In this study, we conducted robust genetic tests to assess whether milk was associated with an increase in heart disease, and while we confirm that milk can cause an increase in body fat, we also show that it leads to lower cholesterol concentration and lower cardiovascular disease risk.
"The risk reduction could be explained by milk calcium, which has shown to increase the enzymes that break down fats within the body and thereby lower cholesterol levels.
"What this shows is that milk can be a part of a healthy balanced diet; there is no need to limit milk consumption if you're looking to improve your heart health."
