How Grapes Prevent Metabolic Syndrome
Lost of people over 40 years old are facing a variety of issues caused by overweight. This is because obesity can cause multiple health problems such as high blood pressure and insulin resistance etc. All of these syndromes are known as the metabolic syndrome which can be an important cause of heart diseases and type 2 diabetes. Metabolic syndrome is not clearly defined by the scientists yet. It usually includes a variety of syndromes such as too much fat on the waist, high triglyceride levels, high blood pressure, reduced glucose tolerance etc.
Some US scientists from the the laboratory at Michigan State University found that eating grapes can effectively lower the risk of metabolic syndrome. Researchers pointed out that regular consumption of grapes can be helpful to lower the blood pressure, improve heart functionality and reduce the risk of heart diseases. Although these facts are still based on lab tests on rats, it is believed to have positive effects for human beings as well.
In the above experiments, various species of rats are feed in the overweight status. Then, they are provided with different types of grape powders (red, green and black) as a part of their daily diets. Scientists will compare the results between the rats with and without grapes products in their diets after a few months. They found that rats which regularly eat grape powders in these three months have a lower blood pressure and less times of inflammation than another group of rats. In addition, they also have a lower triglyceride level and reduced glucose tolerance as well.
The reason for this result is believed that the antioxidants containing in grapes is the key to bring such good benefits for the human body. Grapes contains a large amount of antioxidant phytonutrients. Although there are no experiments performed on human tests yet, the existing data can still be able to confirm that the antioxidants in grapes can help to reduce the risk of cardiovascular diseases and diabetes.
