Walk into any convenience store, and you’ll see a wide variety of energy drinks to choose from. In recent years, news reports have brought attention to some of the consequences of their overuse. Some of these reports document emergency room visits related to mixing energy drinks and alcohol or teens having heart palpitations and dizziness. Some high schools around the nation have banned these products because so many students were “wired” on caffeine and many becoming ill. Are energy drinks as popular and as dangerous as the media portrays them to be? A factsheet from the University of California Cooperative Extension service explores the facts behind these popular products.
- The term energy drink refers to beverages that contain caffeine in combination with other ingredients such as taurine, guarana, and B vitamins purported to supply consumers with extra energy.
- Limited research suggests that energy drinks can improve physical and mental performance, improve driving ability when tired, and decrease mental fatigue after long periods of concentration. However, researchers do not know if these improvements are due to caffeine, herbal ingredients, or a combination of both.
- An 8 ounce serving of energy drink can contain anywhere from 80 to 150 mg of caffeine. The caffeine content is more than that of sodas (22-46 mg per 8 oz serving) but more comparable to tea (48 to 175 mg per 8 oz serving) and brewed coffee (134-240 mg per 8 oz serving). The problem is that most cans contain 2-3 servings, often raising the caffeine intake to over 300 mg per can! Assuming that an adolescent consumes 3 cans per day, caffeine intake can easily exceed over 900 mg (comparable to 9 cups of coffee!)
- Research has suggested that 400 mg or more of caffeine per day can result in nervousness, irritability, sleeplessness, increased urination, abnormal heart rhythms, decreased bone levels, and upset stomach.
- Herbs such as guarana and ginseng can enhance the effects of caffeine. Guarana actually contains caffeine and adds to the total amount. Many of the herbs added to the energy drinks do not have the research based evidence to back up their functional claims.
- Mixing alcohol and energy drinks can be a dangerous combination. Individuals on this mix are more alert but just as intoxicated. In addition, caffeine and alcohol are both diuretics, increasing the likelihood of dehydration and cardiovascular problems.
- A study in the Journal of College Health suggests that energy drink consumption is associated with risk taking behavior such as unprotected sex, substance abuse and violence. Researchers point out that the findings don’t mean the drinks cause the behaviors, rather over consumption should be a red flag for parents that their children might be more likely to take risks.
- A study of 78 youth (11-18 years) found that 42.3% of participants consumed energy drinks.
- Although some beverages are sugar-free, in many the sugar content is comparable to soft drinks (30 g per 8 oz serving). However, since cans often contain 2-3 servings, sugar content could be as high as 90 g per can (equivalent to about 22.5 teaspoons of sugar)! Considering the high rates of obesity, this is another reason to moderate consumption.

Are you prepared for the next disaster or storm? – Live Healthy Live Well
maximios Blog
What does it mean to be prepared? I recently attended a presentation on disaster preparedness sponsored by our local FEMA agency, learning there what I need to do for my household. The FEMA agent explained that their role in an emergency is to coordinate emergency response for larger scale disasters, but they are counting on individuals and families to be prepared ahead of time with enough food, water and supplies to last three days. Listed below are their recommendations.
Make a plan. There are many resources available online to help families make a communications plan and their own plan to survive a disaster. Operation Hope has made available a Personal Disaster Preparedness Guide to help families prepare. http://www.operationhope.org/images/uploads/Files/pdpg.pdf
Stay informed. Use your cell phone’s text messaging capability to receive text message updates from FEMA (standard message and data rates apply).
Here are basic commands to get started:
Get a kit. Households should be stocked with enough food, water and supplies to support physical needs for at least three days following a disaster or storm. Depending on how severe the disaster is, you may need to be on your own longer. Rescue workers come to the scene quickly, but cannot reach everyone right away. Here’s what you’re going to need:
The Basic Supply Kit (from Ready.gov)
The list below is a basic list and may need to be adapted to suit your household. Think about the type of container you keep these supplies in if you need to evacuate your home. When preparing for a possible emergency situation, think first about the basics of survival: fresh water, food, clean air and warmth. In addition, basic services and utilities (electricity, gas, water, sewage treatment, and telephones) may be shut off for several days or longer.
According to Ready.gov, a basic emergency supply kit could include the following recommended items:
According to ready.gov, you may consider adding some of these items to your kit:
For more information, see Ready.gov, Be Red Cross Ready or the Extension Disaster Education Network Family Preparedness course.
Wouldn’t it lend a little peace of mind having such a kit prepared? I’m going to get my kit completed before summer. We can help our community weather a storm or disaster much more successfully if every household is prepared.
