Researchers examined health information from two million Britons and Americans and found that milk drinkers cut their risk of coronary heart disease by 14 percent. Milk is a complex in the way that it contains 18 out of 20 essential proteins and amino acids, but it also contains saturated fats.
Lead study author Vimal Karani, a professor of nutrigenetics and nutrigenomics at the University of Reading, said of the study’s findings: “We found that among participants with a genetic variation that we associated with higher milk intake, they had higher BMI [and] body fat, but importantly had lower levels of good and bad cholesterol.
“We also found that those with the genetic variation had a significantly lower risk of coronary heart disease. All of this suggests that reducing the intake of milk might not be necessary for preventing cardiovascular diseases.”
The collaborative study, consisting of scientists from the UK, Australia and New Zealand were unable to find a link between regular milk consumption and increased levels of cholesterol.
When they analysed readings from previous studies and evaluated the population’s data, the scientists found those who drank more milk had lower levels of blood fat.
However, the authors did find that regular milk drinkers generally have a higher body mass index (BMI) in comparison to non-milk drinkers.
The team took a genetic approach and looked at a variation in the lactase gene associated with digestion of milk sugars known as lactose, and found those carrying the variant is a good way for identifying those who consume more milk.
Though obesity, diabetes, and other conditions that affect metabolism also have ties to an overindulgence in dairy products, Professor Karani said there was no evidence higher milk intake increased the chances of diabetes.
Milk has long been known to help build healthy bones and provide the body with a vitamin and protein boost.
A buildup of fatty plaques in your arteries can damage your blood vessels and heart. Plaque buildup causes narrowed or blocked blood vessels that can lead to a heart attack, chest pain or stroke.
Coronary artery disease symptoms may be different for men and women. For instance, men are more likely to have chest pain. Women are more likely to have other signs and symptoms along with chest discomfort, such as shortness of breath, nausea and extreme fatigue.
Signs and symptoms can include:
Chest pain, chest tightness, chest pressure and chest discomfort (angina)
Shortness of breath
Pain, numbness, weakness or coldness in your legs or arms if the blood vessels in those parts of your body are narrowed
Pain in the neck, jaw, throat, upper abdomen or back.
