Energy Drinks Contain More Caffeine Than Advertised

I’m pretty sure we all know what energy drinks are, and most of us probably drink it for that energy boost to stay awake at night to study for a midterm, final or to write a paper that was left till last minute to do. Everyone needs to be careful about how much caffeine they are consuming, but this is hard to do when the amount of caffeine aren’t even shown correctly on energy drinks. The reason why some companies don’t list caffeine levels is because there is no requirement to do so.

Researchers at Consumer Reports bought 27 top-selling energy drinks and shots and measured the amount of caffeine in each of them. They found that caffeine levels per serving ranged from about 6 mg to 242 mg per serving, some containing more than one serving. 5-hour Energy Extra Strength contained the highest amount, whereas 5-hour Energy decaf contained the lowest amount. They measured that Arizona Energy, Clif Shot Turbo Energy Gel, Nestle Jamba, Sambazon Organiz Amazon Energy and Venom Energy had about 20% more caffeine in it than advertised. Whereas Archer Farms Energy Drink Juice Infused was 70% below the amount of caffeine advertised. For most drinks though, numbers were within 20% of what was listed.

According to an article on Live Science, doses between 200 to 300 mg of caffeine aren’t harmful for adults, but exceeding 500 mg can lead to fast heartbeat, insomnia, and muscle tremors. Pregnant women should consume less than 200 mg daily, and children should not even drink energy drinks, and keep their caffeine consumption to about 100 mg daily. But the amount of caffeine a person can consume before it becomes harmful varies widely.

Even though it is quite scary to think of the outcome of drinking too many cans of energy drinks, it doesn’t mean you should stop drinking them completely. There are still benefits of drinking energy drinks, such as alleviating fatigue and increasing mental alertness which can improve a person’s concentration and focus. But just remember that energy drinks actually contain 20% more caffeine in it than shown on the can, so drink wisely!

Eat Tomatoes!

New research suggests that foods such as tomatoes which contain the antioxidant lycopene may reduce men’s risk of stroke. Lycopene is an antioxidant compound that gives yellow, red, and orange vegetables and fruits their colour because they contain the pigment carotenoid. Papaya, watermelon, guava and apricots are also significant sources of lycopene. Lycopene decrease the formation of plaques in arteries leading to heart attacks and strokes. They also decrease stroke risk by preventing blood clots, blood platelets from clumping together and also inhibiting the production of cholesterol.

Jouni Karppi of the Univeristy of Eastern Finland published an article in the journal of Neurology showing that men who had higher levels of lycopene in their blood were 55% less likely to have a stroke when compared to those with lower levels of lycopene. 1031 men in Finland between the ages 46 and 65 took part in his study. Over the 12-year period of the study, only 67 men suffered a stroke. Most of the men who suffered from a stroke had low levels of lycopene in their blood. Although the study did show that people with higher levels of lycopene have fewer strokes, it did not prove that eating tomatoes reduced the risk of stroke. Karppi said that he will continue to do further research of the role lycopene play in decreasing the risk of chromic vascular disease.

Men should really consider eating more tomatoes. Not only do they have a chance of reducing men’s risk of stroke, but they may also lower the risk of certain type of cancer such as prostate, lung and stomach cancer. So to all the men out there, start to include more tomatoes in your diet! Your body will thank you in the future.

Triclosan: Harmful Chemical Found in Soap

If you take a look at the bottle of soap in your bathroom, triclosan might just be listed as one of the ingredients.  Recent studies have shown that the chemical triclosan may impair muscle function. It is also commonly found in supplies that we use on a daily basis, such as deodorants and toothpastes. First developed in the 1960s, triclosan was used in hospitals to prevent bacterial infections. It was then included into other products such as kitchen utensils, trash bags and bedding once manufacturers were certain that triclosan was able to kill harmful bacteria.

Researchers from the University of California did a study and found that triclosan does impair muscle function in both humans and animals. In their study, they isolated human muscle cells from the heart and skeletal muscles and exposed them to triclosan. They also tested how mice and fathead minnows would react to triclosan. Results showed that in the isolated human muscle cells, triclosan interrupted two proteins, important for proper muscle functioning from communicating. In the mice, the function of the heart muscle was reduced by 25% and there was also an 18% reduction in grip strength. The fathead minnows exposed to triclosan were found to be worse swimmers when compared to fathead minnows that weren’t exposed to triclosan. These results definitely show that exposure to triclosan can impair muscle function, especially cardiac function. According to the U.S. Food and Drug Administration, triclosan is not known to be any more hazardous than just washing with non-antibacterial soap, but further studies will be done and reviewed to the public in winter 2012.

There are certainly strong evidences provided to show how we should be concerned about triclosan being used in products. Experts are concerned that a resistant bacteria strain will develop with prolong use of this chemical. Although triclosan isn’t regulated as a drug, it should still be a concern to human health and the environment. Hospitals should continue using antibacterial soap that contains triclosan because it is important in preventing the spread of bacteria from one patient to another. But antibacterial soap that contains triclosan really isn’t needed for household hang washing. According to Dr. Peter N. Wenger, the most effective way of getting rid of bacteria on your hands is to wash thoroughly, making sure to also wash between the fingers. So try to buy triclosan free soap and remember to wash your hands thoroughly to prevent the spread of bacteria!
