A glass of milk each day can significantly reduce the risk of suffering from heart disease, according to a new study.

A team of researchers also found milk drinkers have lower levels of cholesterol, which can block arteries and lead to heart attacks.

According to The Daily Mail, those who drink milk each day slashed their risk of coronary heart disease by 14 percent. By studying the health information of two million Britons and Americans, scientists discovered those with a mutation enabling them to consume large amounts of milk were less prone to cardiovascular illnesses, the German News Agency reported.

The new finding comes as a growing body of evidence is showing that dairy products can actually be good for your health. Past studies had previously concluded that dairy products were bad.

Professor Vimal Karani, lead author and a nutritionist at the University of Reading, said: "We found that among participants with a genetic variation that we associated with higher milk intake, they had higher BMI, 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."

When they pooled data from the UK Biobank study, and the Health and Retirement study from the US, the scientists found those who drank more milk had lower levels of blood fats.

However, the authors did find that regular milk drinkers generally have a higher body mass index (BMI) in comparison to non-milk drinkers. Though obesity, diabetes, and other conditions that affect metabolism also have ties to an overindulgence in dairy products, Karani said there was no evidence higher milk intake increased the chances of diabetes. The latest findings were published in the International Journal of Obesity.

Scientists: Melting Sea Ice in Antarctica Causes Ocean Storms

The record-breaking retreat of Antarctic sea ice in 2023 has led to more frequent storms over newly exposed parts of the Southern Ocean, according to a study published Wednesday.
Scientists know that the loss of Antarctic sea ice can diminish penguin numbers, cause ice shelves to melt in warmer waters, and impede the Southern Ocean from absorbing carbon dioxide, AFP reported.
But this new research, published in the peer-reviewed journal Nature, explores another consequence: increased heat loss from the ocean to the atmosphere, and an associated rise in storms.
Since 2016 there has been a large-scale reduction in Antarctic sea ice, but nothing like 2023 when a record amount failed to reform over the winter.
For this study, Simon Josey of the UK's National Oceanography Center and colleagues focused on three regions that experienced unusually high levels of sea-ice retreat that year.
Using satellite imagery, ocean and atmospheric data, and wind and temperature measurements, they found some newly ice-free areas experienced double the heat loss compared to a stabler period before 2015.
This was accompanied by "increases in atmospheric-storm frequency" over previously ice-covered regions, the authors found.
"In the sea-ice-decline regions, the June–July storm frequency has increased by up to 7days per month in 2023 relative to 1990–2015."
The loss of heat caused by reduced sea ice could have implications for how the ocean circulates and the wider climate system, the study added.
Oceans are a crucial climate regulator and carbon sink, storing more than 90 percent of the excess heat trapped near Earth's surface by greenhouse gas emissions.
In particular, sea-ice retreat could mean changes in how a deeper layer of cold, dense Antarctic bottom water absorbs and stores heat.
The authors said further in-depth analysis of possible climate impacts were needed, including if sea-ice retreat could have even further-reaching consequences.
"Repeated low ice-cover conditions in subsequent winters will strengthen these impacts and are also likely to lead to profound changes further afield, including the tropics and the Northern Hemisphere," it said.
