Full-fat milk is better for the heart, a study shows

Tehran(KNA): Base on a study in European Journal of Clinical Nutrition, Full-fat milk is better for the heart because it increases levels of good cholesterol, finds study.

For decades, skimmed or semi-skimmed milk has been hailed as a healthier option.

But full-fat milk may be better for the heart, according to new research.

A team at the University of Copenhagen in Denmark has found it boosts levels of 'good' High-density lipoprotein (HDL) cholesterol in the bloodstream.

Study participants' low density lipoprotein (LDL) or 'bad' cholesterol levels did not differ significantly between the two types of milk.

High cholesterol is associated with increased risk of coronary heart disease, strokes and vascular diseases. It is particularly dangerous as it often goes undiagnosed and therefore untreated.

Good cholesterol has a positive effect by carrying away bad cholesterol from the arteries and back to the liver where it is broken down and passed from the body.

Previous studies have shown full fat dairy is also linked with lower risks of diabetes. 

The study authors say their findings add weight to the notion that full fat milk is no worse than low fat and may even be healthier.

Their report stated: 'Dietary guidelines have for decades recommended choosing low-fat dairy products due to the high content of saturated fat in dairy known to increase blood concentration of LDL cholesterol.

'But studies show no association between overall dairy intake and risk of cardiovascular disease and even point to an inverse association with type 2 diabetes.

'Our findings suggest whole milk might be considered a part of a healthy diet among the healthy population.'

Scientists gave volunteers either 500ml per day of either skimmed milk or whole milk for three weeks, and then repeating the test with the other type of milk.

The study was randomised so that some participants started with skimmed milk whereas others started with the whole milk first.

Cholesterol tests were taken to measure how the different types of milk affected blood lipids such as LDL cholesterol and HDL cholesterol.

In total 18 healthy adults took part in the study and all but one completed it.

Experts have long recommended switching to skimmed or semi-skimmed milk, as well as other low-fat dairy products, to prevent your arteries becoming clogged, raising the risk of a heart attack or stroke.

As a result, sales of low-fat dairy products have rocketed in recent years.

In 2016, the same team found eating low-fat cheese did not lower cholesterol, reduce blood pressure or help your waistline.

Volunteers who eat a daily portion of regular fat-cheese, or a low-calorie option, for three months saw little or no difference in heart disease risk by the end of the experiment.

The study was published in the European Journal of Clinical Nutrition.
