PostSubject: Energy Drinks: Are they good or bad for you?   Thu Nov 08, 2007 7:40 pm

Now a days, energy drinks are a top source to get the caffeine and to get energized during the day. But are they really good for you?

In a study done by the American Heart Association, they found that energy drinks increases your heart rate and your blood pressure, which could lead to an increase risk of heart disease.

In this study, 15 healthy young men and women drank two cans of an energy drink that contained 80 milligrams of caffeine every day for a week. All agreed to abstain from any other forms of caffeine for two days prior to and throughout the study. Within four hours of consuming the drinks on the first day, systolic blood pressure (the top number) shot up by 9 points; on the seventh day, it rose 10 points. Diastolic blood pressure (the bottom number) rose 5 points on both days, Dr. Kalus says. Heart rate increased five beats per minute on the first day; seven days on the last. The volunteers were sitting in a chair, watching a movie, when the changes occurred, he says.

This doesn't go against the fact that if you are involved in excessive amounts of physical activity it is bad for you, but for a sedentary individual who doesn't work out as much energy drinks are not the way to go.

A recent review of a dozen popular drinks in Consumer Reports found caffeine levels, which often aren't listed on the label, can top 200 milligrams per bottle or can. While the energy drink used in the study had as much caffeine as one to two cups of coffee. Energy drinks contain taurine, an amino acid found in protein-rich foods like meat and fish. The guideline for protein consumption after exercise is 1 gram for every 3-4 grams of carbohydrate. most Americans, including athletes, get enough protein in their diets. Excess protein is not used by the body; instead, it is excreted in urine.

And coffee has phenol, an antioxidant that has been shown to reduce the risk of heart disease.

These are just some things to think about when you are looking for some extra energy in your day.
