Heart disease remains the leading cause of death around the world. Millions of people die every year from heart attacks, strokes, and other serious heart conditions.
One of the biggest reasons behind these problems is a disease called atherosclerosis. This condition develops slowly over many years when fatty material builds up inside the arteries. These fatty deposits are known as plaques.
Arteries are blood vessels that carry oxygen-rich blood throughout the body. When plaque builds up, the arteries become narrower and harder. Blood can no longer flow as easily as it should.
Over time, this may lead to chest pain, heart attacks, strokes, or even sudden death. Many people do not realize they have atherosclerosis until a major health emergency happens.
A major cause of plaque buildup is a condition called dyslipidemia. This means there are unhealthy levels of fats in the blood. These fats include cholesterol and triglycerides.
Cholesterol itself is not always harmful because the body actually needs some cholesterol to build cells and produce hormones. However, too much “bad” cholesterol can stick to artery walls and form plaque.
Doctors estimate that nearly half of adults have some form of dyslipidemia. Poor diet, lack of exercise, obesity, smoking, diabetes, and genetics can all raise the risk.
Current medicines, including statins, can help lower cholesterol and reduce the risk of heart attacks. These drugs have saved many lives. However, they usually cannot completely remove plaque that has already formed inside arteries.
Now, scientists may have discovered an unexpected new way to fight this dangerous disease. Two recent studies suggest that manganese, a mineral already found naturally in food, might help lower blood fat levels and even reverse plaque buildup in arteries.
Manganese is a trace mineral, meaning the body only needs very small amounts of it. It is naturally found in foods such as nuts, whole grains, beans, spinach, and tea. The mineral helps support many important body functions, including metabolism, enzyme activity, wound healing, and bone development.
But researchers now believe manganese may also play a major role in controlling how fats move through the body. This surprising discovery has attracted a lot of attention from scientists studying heart disease.
The new research showed that larger amounts of manganese, even when given through food, helped lower levels of cholesterol and triglycerides in the blood. In studies involving mice with heart disease, the mineral also reduced plaque buildup inside the arteries.
The studies focused on tiny particles in the blood called lipoproteins. These particles act like transport vehicles that carry fats throughout the body. Cholesterol and triglycerides cannot move through the bloodstream by themselves, so they rely on lipoproteins for transport.
The scientists discovered that manganese affects a transport system inside cells known as COPII, short for coat protein complex II. This system helps move proteins and fats around the body. Manganese appears to bind to the COPII system and change how it works.
One of the most interesting findings was what researchers described as a “bell-shaped” effect. This means manganese only works best within a certain range. Too little may not have much effect, while too much may not provide additional benefits. At the right level, however, manganese significantly lowered blood fat levels.
The researchers believe this effect may help explain how manganese reduced plaque in the arteries of mice. By changing the way fats are transported through the body, the mineral may help stop fatty material from collecting inside blood vessels.
Dr. Xiao Wang, one of the lead researchers involved in the studies, described the findings as a major breakthrough. He explained that manganese could potentially become a new tool for preventing and treating heart disease in the future.
Still, scientists are being careful not to raise expectations too quickly. The research has only been carried out in animals so far. Human bodies are much more complex, and treatments that work in mice do not always work the same way in people.
Researchers also need to make sure that larger doses of manganese are safe. Although manganese is necessary for good health, too much can become harmful, especially to the nervous system. Scientists will need to carefully study the right dose and long-term safety before any treatment becomes available.
Even so, the discovery offers exciting hope. Heart disease remains incredibly common despite decades of medical progress. Many people struggle to control cholesterol levels even with medication and healthy habits. A natural and affordable mineral that could help clear plaque from arteries would represent a major advance in medicine.
Until more research is completed, experts still recommend following proven steps to protect heart health. Eating a healthy diet, staying physically active, avoiding smoking, controlling blood pressure, and managing cholesterol levels remain some of the best ways to lower the risk of heart disease.
Scientists are also continuing to study many other possible ways to improve heart health. Some studies suggest that certain herbal supplements may affect heart rhythm. Other research shows that eating eggs in moderation may not be as harmful as once believed and may even lower heart disease risk in some people.
Researchers are also developing new medicines designed to prevent heart attacks more effectively. Some studies even suggest that certain heart medications may help reduce the risk of severe COVID-19 complications.
Nutrition also remains an important area of research. Scientists continue to study foods that support heart health, including fruits such as oranges and nutrient-rich foods like black beans. Healthy eating patterns may help reduce obesity, diabetes, and high cholesterol, which are all major risk factors for heart disease.
The new manganese findings were published in the journal Life Metabolism. While it may take years before manganese-based treatments become available, the discovery highlights how even small nutrients inside everyday foods may have powerful effects on human health.
Future research may reveal entirely new ways to prevent heart disease and help people live longer, healthier lives.
