Is Coconut Good for You?

From VOA Learning English, this is the Health & Lifestyle report.

Americans love food trends. Much like clothing, some foods are more popular at times than others. The United States is currently experiencing a coconut craze.

Janette Rizk is a spokesperson for a popular store called Whole Foods Market in the United States. It has sold coconut water and coconut oil for years. But, Rizk says she has seen an increase in other coconut products in the stores she represents.

"We're seeing coconut oil in natural beauty products. We're also seeing things like the meat of the product being used in everything from flours, to tortilla chips, to milks and butters."

Some health experts say coconut can help fight infection in the body and raise its levels of good cholesterol.

Elissa Goodman is a holistic nutritionist. She says coconut has many health benefits.

Is Coconut Good for You?

"It revs up your metabolism. It also acts as an anti-viral, anti-bacterial, anti-fungal. So, it's great for the immune system. It's great for the heart. It raises your HDL (High-density lipoprotein) and it also is great for like any kind of urinary tract infections, any kidney issues, weight. I mean, the possibilities of using coconut oil for your health (are) endless."

HDL is what doctors callgood cholesterol.” Low-density lipoprotein, or LDL, is bad.

The Centers for Disease Control and Prevention in the U.S. provides information about cholesterol on its website. It says most of the bodys cholesterol is LDL. High levels of LDL cholesterol can block arteries, the tubes that carry blood from the heart to the rest of the body. The blockages can lead to heart disease and stroke.

The CDC website says HDL cholesterol helps remove LDL cholesterol from the body. High levels of HDL cholesterol can reduce the risk for heart disease and stroke.

Walter Willett is a doctor and nutrition expert at Harvard Universitys School of Public Health.

Willett says there isnt yet enough research about how coconut oil affects the body to claim it is healthful. However, scientists and nutritionists do know the makeup of coconut.

Unlike other plant-based oils, coconut oil is a saturated fat. Willett explains thatcoconut oil is about 90 percent saturated fat, which is a higher percentage than butterwhich has about 64 percent.

Saturated fats are in animal fats, such as butter, meat, egg yolks, and in some plants like coconut and palm oils. In humans, saturated fat often increases cholesterol levels in the blood.

Unsaturated fats often come from plants. Eating foods high in unsaturated fats can reduce the amount of cholesterol in the blood.

Willett says thattoo much saturated fat in the diet is unhealthy because it raises LDL cholesterol levels, which increases the risk of heart disease. But coconut oil also increases HDL cholesterolthe good cholesterol.

So, Dr. Willett says it isless badthan saturated fats that do not raise HDL levels.

Coconut oil might not be the new super health food that some claim. But moderate use in cooking could be a good for some people.

An important note when buying coconut oil: Look forvirginon the label. Make sure it is not hydrogenated or partially hydrogenated.

Hydrogenation is a chemical reaction that turns unsaturated fats into saturated ones. Hydrogenated fats are also called trans fats. The CDC says trans fats raise your bad cholesterol and may even lower good cholesterol.

And that's the Health & Lifestyle report.
