Green coffee beans—health or hype?

Weight-loss supplements with green coffee beans have been popular lately, but some products have more in them than just coffee beans. Get the facts about ingredients and always read product labels carefully.

It can be tough figuring out the truth about the health benefits of many natural products. One product that’s getting a lot of attention these days is green coffee beans. As a Warfighter looking for ways to optimize your performance or perhaps drop some weight quickly, it’s easy to be overwhelmed by all the marketing hype and claims, especially if it’s an appealing message. Make sure you get the facts.

Green coffee beans are the raw, unroasted seeds or “beans” of the Coffea plant. They contain a chemical called chlorogenic acid (CA) that supposedly offers some health benefits. Roasting reduces the amount of CA in coffee beans; as a result, green coffee beans contain more CA than the roasted beans you use for your morning coffee. Some research suggests that CA might prevent heart disease, diabetes, and high blood pressure, and help with weight loss. But it’s important to note that most of this research is preliminary, and there just isn’t enough evidence to say that CA will definitely help with any of these health conditions.

Although no serious side effects have been reported from green coffee beans in their natural form, some dietary supplement products containing green coffee beans have been found to contain undeclared drugs, insects, and mold. Of the 126 products containing green coffee beans ranked by the Natural Medicines Comprehensive Database, 40 have been assigned a rating of “1” or “2,” which indicates there are serious concerns about their safety and effectiveness. None have a rating in NMCD’s green zone, which suggests that there are some concerns about them all. Note also that green coffee beans are not always the only active ingredient, so be sure to check the product label.

It’s also important to note that green coffee beans contain caffeine. Side effects of consuming too much caffeine are all too familiar—difficulty sleeping, rapid or irregular heartbeat, nervousness, nausea, and vomiting. Pregnant and breastfeeding women, or those who have been diagnosed with certain medical conditions (including anxiety, diabetes, irritable bowel syndrome, high blood pressure, or osteoporosis) should check with their doctor before consuming green coffee beans.

Energy drinks and service members

Energy drink consumption among service members may lead to sleep issues.

The Centers for Disease Control and Prevention (CDC) has reported that the consumption of energy drinks by service members can lead to sleep deprivation and impaired performance. The report outlines a study of more than 1,200 service members deployed in Afghanistan that found roughly 45% of those surveyed consumed at least one energy drink daily. Those who consumed three or more energy drinks per day—about 14%—had sleep issues that disrupted their performance. While more research is needed to determine the full effects of energy drink consumption on sleep, service members should be aware of their daily caffeine consumption.

FDA investigating adverse events linked to energy drinks

Reports of adverse events —including five deaths—possibly linked to Monster Energy drinks are under investigation by the FDA.

The Food and Drug Administration (FDA) is investigating five deaths and a non-fatal heart attack that may be linked to Monster Energy drinks. The FDA has pointed out that while the investigation is going on, it does not mean that Monster Energy drinks caused these adverse events, which were reported to the FDA over a span of eight years. Other adverse event reports have been associated with consuming the energy drinks. Read the New York Times article here, as well as this one from NBC News.

When it comes to performance—you booze, you lose

Going out for a drink to celebrate after a long race or a tough workout may be good for the soul, but it’s bad for performance.

Before you reach for a cold one, consider that drinking alcohol before, during, or after exercise can be detrimental to your performance, especially when consumed in excess. The effect of alcohol on skeletal muscles has been found to decrease strength output and can cause muscle cramps, pain, and loss of proprioception. Alcohol can also negatively affect your metabolism during exercise and contribute to dehydration. There is a shortage of data on the effects of alcohol on a recovering athlete, but some studies have shown that alcohol slows the recovery process by impacting muscle growth and repair systems. While current research has shown that alcohol in moderation can have other health benefits, it may be better to save that drink for when your physical performance is not on the line. There is also a growing body of research investigating the effects of combining alcohol with energy drinks. Many energy drinks contain substances and supplements that can interfere with normal alcohol metabolism and impair judgment. Be a conscious consumer and know what kinds of ingredients may be risky for your health.

Keep fit to reduce your risk of breast cancer

Exercise is beneficial for women in the prevention and treatment of breast cancer. A new study finds that it’s never too late to start exercising to reduce your risk.

October is National Breast Cancer Awareness month and Military Health’s Women’s Health Awareness Month. The international pink ribbon symbol represents a community dedicated to awareness and prevention of breast cancer, a disease that mostly affects women. According the National Cancer Institute, there were over 220,000 new diagnoses of breast cancer in 2012 and more than 39,000 related deaths in the U.S. This puts breast cancer as the nation’s second leading cause of death among women (after heart disease).

What can you do to reduce your risk? A new study of more than 3,000 women found that those who exercised 10-19 hours a week during their reproductive years lowered their risk of getting breast cancer after menopause by one third. Women who started exercising after the onset of menopause also lowered their risk by about 30% with 9-17 hours of exercise per week. Researchers concluded that women can reduce their risk for breast cancer through a physically active lifestyle. The link between exercise and breast cancer is not fully understood, and research continues, but if ever you needed a good reason to start exercising or keep exercising, this is a good one. You can learn more about breast cancer and other women’s issues on the Women’s Health page of

In conjunction with the DoD campaign, Operation Live Well, HPRC will be highlighting important issues related to both military and family health.

DMAA list update for October 2012

HPRC’s latest review of DMAA-containing products shows that 89 have been discontinued or reformulated since the list was first compiled nine months ago.

HPRC’s list of DMAA-containing dietary supplement products has been reformatted, revealing that many are no longer being manufactured or distributed. A number of manufacturers now indicate on their websites that products previously containing DMAA have been reformulated. DMAA-containing versions of discontinued or reformulated products are likely to be on the market until retail supplies have been exhausted, so check labels carefully for ingredients. However, the only way to be certain a product no longer contains DMAA is through laboratory testing.

Lack of exercise is just as bad as smoking

It’s no news that smoking is bad for your health, even deadly. But a new study found that lack of exercise can be just as fatal.

A new study published in the Lancet reports that one in 10 premature deaths worldwide is related to lack of exercise, equal to 5.3 million deaths in 2008. It seems as though inactivity has become as deadly as tobacco. More specifically, researchers estimated that lack of exercise causes about 6% of heart disease, 7% of Type 2 diabetes, and 10% of colon and breast cancers worldwide. To put this in perspective, the failure to spend 15-30 minutes a day doing activities such as brisk walking could shorten your life span by three to five years. Lack of physical activity is certainly a global epidemic, but it is also highly preventable. Check out HPRC's resources on how to get you and your family physically active.

Consumer Reports on 10 hazards of dietary supplements

The Consumer Reports website recently posted an article outlining the potential dangers of dietary supplement products.

People take dietary supplements for lots of different reasons, and some may take them because they believe they are “natural” and therefore safe. A new article from lists 10 hazards of taking dietary supplement products, pointing out that supplements are not risk-free.

FDA reports dietary supplement manufacturing violations

About half of those dietary supplement manufacturers inspected by FDA found to have manufacturing violations.

The U.S. Food and Drug Administration (FDA) has found violations in manufacturing practices in half of almost 450 dietary supplement companies it has inspected over the last four years, according to a Chicago Tribune article. The implications of these findings can have serious health problems for consumers. Since dietary supplement manufacturers are the ones responsible for ensuring a product is safe before it is marketed, the FDA inspects companies to check for compliance and takes action only if a product is deemed unsafe after it has been marketed. For more information, see the FDA website’s Dietary Supplements section.
