Energy Drinks and Our Children



By Gariane Phillips Gunter, M.D.




I was giving a talk to a group of fifth graders regarding mental health issues when one young man raised his hand to ask a question. His question caught me a little off guard as he asked me about using energy drinks. 




Out of curiosity, I asked the group of 100 students to raise their hand if they drank these drinks. To my amazement, most hands went up!!! I then asked them where they got the drinks and they responded that their parents bought them for them. These children opened my eyes to a real problem.




Many children and teens today are choosing energy drinks as a part of their daily diet. And while some energy drinks are clearly labeled as unsuitable for children, others are specifically marketed to kids as young as four, promising boosts in energy and nutrition as well as enhanced athletic performance.




The problem is that this energy boost comes with a price. Most energy drinks, although packaged in smaller cans and bottles than regular soft drinks, are packed with sugar and caffeine — sometimes as much caffeine as in 1 to 3 cups of coffee! Too much sugar can put your child in the fast lane to the dentist's office and also contribute to weight gain. Excessive caffeine comes with its own set of problems — especially in younger kids, it can negatively affect attention and concentration as well as restful sleep.




As adults, we know how it feels to have too much caffeine and our children are no exception. Caffeine by design is a stimulant — though a widely used and accepted one — and because children are smaller than adults and haven't yet developed a tolerance to it, its effects on them may be more pronounced. As in adults, too much caffeine can cause:



• jitteriness and nervousness 

• upset stomach 

• headaches

• difficulty concentrating 

• difficulty sleeping 

• frequent urination



Many of these drinks also contain additional ingredients whose safety or effectiveness has never been tested in children — including herbal supplements, guarana (a source of caffeine), and taurine (an amino acid thought to enhance performance). Children and teens may ingest these drinks without realizing the potential danger. Even mild caffeine toxicity can cause nausea, vomiting hypertension, accelerated heart rate and tremors. Because the Food and Drug Administration does not regulate these drinks it is not possible to know the exact quantities, ingredients or effects they may cause. 




Despite all the hype, energy drinks offer no real health benefits or competitive edge for kids. A balanced diet, physical activity and adequate sleep will work to give our children all the energy they need, safely.

Stimulation from Caffeine Counters Memory Loss

Consider that coffee is known for its antioxidant capacity and as an antioxidant it is also anti-inflammatory.

We have always encouraged organic coffee to offer a higher level of polyphenol benefit. If you'd like to purchase organic and fair trade coffee from us please let us know. We'll be happy to provide you with our list of organic coffee varieties.
Caffeine reverses memory impairment

MIAMI, July 6 (UPI) -- Memory impairment was reversed in aged mice, bred to develop symptoms of Alzheimer's disease, after they were given caffeine, U.S. researchers said.

Researchers at the University of South Florida said back-to-back studies show caffeine significantly decreased abnormal levels of the protein linked to Alzheimer's disease -- both in the brains and in the blood of mice exhibiting symptoms of the disease.

Both studies build upon previous research by the University of South Florida that showed caffeine in early adulthood prevented the onset of memory problems in mice bred to develop Alzheimer's symptoms in old age.

"The new findings provide evidence that caffeine could be a viable 'treatment' for established Alzheimer's disease, and not simply a protective strategy," lead author Gary Arendash said in a statement. "That's important because caffeine is a safe drug for most people, it easily enters the brain, and it appears to directly affect the disease process."

The Alzheimer's mice received the equivalent of five 8-oz. cups of regular coffee a day -- 500 milligrams of caffeine.

In the study, half of the 55 mice genetically altered to develop memory problems mimicking Alzheimer's disease were given caffeine, and half were given water. At the end of the two-month study, the caffeinated mice performed much better on tests measuring their memory and thinking skills.

The study was published online in the Journal of Alzheimer's Disease.
