From Learning English, this is Science in the News. Im Faith Lapidus.
And Im Mario Ritter. Today we tell about herbs and spices, and some of their many uses.
People have been using herbs and spices for thousands of years. Generally, herbs come from the green leaves of plants or vegetables. S// from other parts of plants and trees.
Some herbs and spices are valued for their taste. They help to sharpen the taste of many foods. Others are chosen for their smell. Still others were used traditionally for health reasons.
When people think of improving their diet, they often talk about eating more fruits and vegetables. Others want to eat more fish and less red meat, in addition to reducing the amount of food they eat. But, they can improve their diets even more with just a simple addition.
American researchers have found that a diet rich in spices can help reduce the harmful effects of eating high fat meals. Researchers at Pennsylvania State University reported the findings.
Penn State Associate Professor Sheila West led an investigation of the health effects of a spice-rich diet. Her team knew that a high-fat meal produces high levels of triglycerides, a kind of fat, in the blood.
She said, If this happens too frequently, or if triglyceride levels are raised too much, your risk of heart disease is increased. We found that adding spices to a high-fat meal reduced triglyceride response by about 30 percent, compared to a similar meal with no spices added.
