From full-fat, semi-skimmed and skimmed to an abundance of dairy-free alternatives, the milk aisle is never short of choices.
However, with the options varying in fat content, the way that you top up your morning coffee could have negative consequences.
Published in The American Journal of Clinical Nutrition, a Norwegian study spanning across three decades has revealed that fat content in milk could be a contributing factor to cardiovascular health.

Those who consumed full-fat milk were afflicted with a higher mortality risk

Having assessed 73,860 people with an average age of 41, the research team identified that 8,590 out of a total of 26,393 deaths were down to cardiovascular disease.
The scientists further identified that those who consumed full-fat milk had a higher mortality risk than those who opted for low-fat milk.
"Dietary guidelines worldwide often recommend consuming low-fat or fat-free dairy products over full-fat alternatives partly due to concerns about saturated fatty acids (SFA) in dairy products," the authors wrote.
"Dairy products are among the primary sources of SFA, which are positively associated with cardiovascular disease and all-cause mortality."
Saturated fats can drive up total cholesterol, leading to potential blockages to form in arteries in the heart and across the body, experts at Harvard have warned.
As a result, most nutritionists recommend limiting the consumption of such fat to around 10 per cent of your calories a day.

Analysing data from three cardiovascular health screenings from between 1974 and 1988, the Nordic team deployed a unique methodology to reach their conclusion.
In Norway, people tended to drink whole milk in the 1970s, a favourite which was swapped out for low-fat in the 1980s.
Consequently, researchers could assess the long-term health benefits and drawbacks for both variations of the drink.
The study found a 22 per cent higher risk of all-cause mortality for those who drank the most milk. Their risk of death by cardiovascular disease was increased by around 12 per cent.
However, when comparing those who drank full-fat and low-fat milk, those drinking low-fat milk acquired a seven per cent lower risk of cardiovascular disease.
The findings stayed stable when accounting for those who suffered early deaths or those who had pre-existing conditions.
Interestingly, those who opted for the lower-fat option tended to be female, of higher education, and did not smoke.
For better heart health outcomes, opt for lower-fat milk varieties

The same train of thought has been echoed by medical professionals at the Mayo Clinic, who warn about the health impacts of saturated fats.
Of course, milk offers protein, calcium and potassium as well as an array of beneficial vitamins to nurture and nourish the body as part of a healthy, balanced diet.
However, the fat present in some options can increase low-density lipoprotein (LDL) cholesterol, increasing your chances of developing cardiovascular disease and suffering a stroke.
As a result, the NHS recommends reaching for lower-fat milks, urging individuals to swap to one per cent fat or skimmed varieties - both of which maintain the nutritious elements of full-fat milk.
