Heart disease is the biggest cause of death around the world. Millions of people die every year from heart attacks, strokes, and other problems that affect the heart and blood vessels.
These diseases often develop slowly over many years before they cause serious health problems. Because of this, scientists are always looking for new ways to protect the heart and lower the risk of life-threatening illness.
One of the main causes of heart disease is a condition called atherosclerosis. This happens when fatty material slowly builds up inside the arteries, which are the blood vessels that carry oxygen-rich blood throughout the body.
Over time, these fatty deposits, called plaques, make the arteries narrower and harder. This reduces blood flow. If a plaque suddenly breaks open, a blood clot can form and completely block the artery. When this happens in the heart, it can cause a heart attack. If it happens in the brain, it can cause a stroke.
A major reason plaques develop is dyslipidemia. This means there are unhealthy amounts of fats in the blood, including cholesterol and triglycerides. Cholesterol is needed by the body in small amounts, but too much of the harmful types can stick to artery walls.
Triglycerides are another kind of fat that stores extra energy from food. High levels of both increase the risk of heart disease. Researchers estimate that almost half of adults have unhealthy blood fat levels.
Doctors often prescribe medicines such as statins to lower cholesterol. These medicines can greatly reduce the chance of heart attacks and strokes. They also help make plaques more stable, making them less likely to break open. Even so, plaques often remain inside the arteries, which is why scientists continue searching for better treatments.
A new study has now suggested that manganese, a mineral already needed by the human body, may offer another way to improve heart health. Manganese is important for many normal body functions.
It helps support healthy bones, assists enzymes that carry out chemical reactions, and plays a role in normal metabolism. Researchers have now discovered that it may also help lower blood fat levels and reduce plaque buildup.
In the study, scientists tested manganese in mice that had atherosclerosis. The animals received different amounts of the mineral. The researchers found that manganese lowered cholesterol and triglyceride levels. It also reduced the amount of plaque inside the arteries.
These findings suggest that manganese may help slow or even reverse some of the damage caused by heart disease, at least in animals.
The research team also wanted to understand how manganese produced these effects. Fats cannot travel through the bloodstream on their own. Instead, they are carried by tiny particles called lipoproteins. The body uses a transport system known as COPII to help package and move these fat-carrying particles.
The scientists found that manganese interacts with this transport system. By changing how COPII works, manganese appeared to reduce the amount of fat entering the bloodstream, leading to lower cholesterol and triglyceride levels.
Lead researcher Dr. Xiao Wang said the results are encouraging. He believes that treatments based on manganese could one day become a new way to prevent or treat heart disease. However, he also stressed that this research is still in its early stages.
The study was carried out in mice, not people. Many treatments that work well in animals do not always have the same results in humans. More laboratory studies and carefully designed clinical trials will be needed before doctors know whether manganese is safe and effective for patients.
Even though this discovery is promising, experts say people should continue following proven ways to protect their hearts. Eating a healthy diet with plenty of fruits, vegetables, whole grains, beans, and healthy fats can help keep cholesterol under control.
Regular physical activity, avoiding smoking, maintaining a healthy weight, controlling blood pressure, and following medical advice are still the best ways to lower the risk of heart disease.
Scientists are also studying how everyday foods may affect heart health. Some research suggests that eating eggs in moderation may fit into a healthy diet for many people. Other studies have explored how foods such as oranges and black beans may support heart health while also helping lower the risk of obesity and type 2 diabetes.
Researchers are also investigating herbal products, although some supplements may affect heart rhythm or interact with medicines, so people should always speak with their doctor before using them.
The new manganese study offers fresh hope that a simple and widely available mineral could become part of future treatments for clogged arteries. While much more research is needed, the findings give scientists a new direction to explore in the fight against one of the world’s deadliest diseases.
