Drink Tea for Your Health
Since the ancient times, Chinese have been drinking tea. They have believed and reported health benefits from tea. It has been used as a medicine in China for at least 4,000 years. Today, there are numerous studies showing evidences improvements in health attributed to tea drinking. More and more people drink tea for their health.
In the Journal of National Cancer Institute (published in 1994) they claimed that drinking tea has reduced the risk of esophageal cancer in Chinese men and women by a huge 60 percent. While, the University of Purdue researchers claimed that green tea can prevent the growth of some cancer cells. Tea has polyphenols that can reduce risk not only of esophageal cancer, but also gastric and skin cancers.
It can also help in the prevention or the spread of prostate cancer as discovered by the Center of Human Nutrition at UCLA. It can also protect the body against cancer brought about by smoking. Green tea and white tea are significant in fighting colon and lower stomach cancers.
Tea can also improve the ratio of good and bad cholesterol levels in your body. The same polyphenols help in preventing blood from clotting and are responsible in lowering cholesterol levels. Thus, drinking tea is a great help for heart disease patients.
These are not only the health benefits attributed to tea. According to Newcastle University’s Medicinal Plant Research Centre study, tea might also delay Alzheimer’s disease. While, University of Tokyo stated that tea may play a role against fighting AIDS.
Aside from cancer it can also be helpful in rheumatoid arthritis, cardiovascular disease, infections, and impaired immune function. There are also new studies claiming green tea helping those who would like to lose weight. Those who drink caffeine and green tea tend to burn more calories that those consuming caffeine only.
Because of its ability to fight and destroy bacteria, green tea can even fight against tooth decay. It can kill dental plaque just as it can help prevent food poisoning. In the market, there are also deodorants and skin creams with the component of green tea in it.
How can something be this good?
The secret is the polyphenols, especially the epigallocatechin galleate or EGCG. ECGC is an anti-oxidant. This powerful anti-oxidant can kill or prevent the growth of cancer cells without harming the healthy tissue and cells. It also has flavonoids and catechins which are also anti-oxidants. It also has fluoride which is why it can fight tooth decay and helps control bad breath.
Different kind of teas has different levels on anti-oxidants. White tea has more anti-oxidants compared to other tea. Freshly brewed teas have more polyphenols than instant or bottled teas. Thus, freshly-brewed teas have more anti-oxidants than instant teas.
Caffeine is also present in tea. Caffeine levels or amount in brewed tea depends on the type of the tea. Black tea has higher amount of caffeine than green tea. The amount of caffeine also depends of length of time of brewing, and also on the water temperature. If the leaves are exposed to higher water temperature, more caffeine are drained from the leaves.
The American Diabetic Association reported that a cup of tea has an average of 40 mg. of caffeine. A cup of freshly brewed coffee has an average of 85 mg. of caffeine. An average of 350 mg. of caffeine consumption is still good for a healthy individual.
Currently, the only negative effect reported in drinking too much tea is insomnia. This would be because of the caffeine content of tea. So start brewing your tea, drink for your health.

Energy Drinks May Not be Healthy at All
Energy drinks may not be as healthy as we think it is. Energy drinks are just everywhere. You can get some in corner stores, gas stations, and bars. Because these drinks are supposed to provide mental and physical stimulation, people are taking it. But does this drink provide what is best for our health?
There are studies showing that energy drink consumption provides relative improvement in mental and cognitive performances. These drinks also increase the alertness of the consumer. But on the down side, excessive consumption may lead to anxiety, insomnia and irritability.
What are the components of your average energy drink?
Some common ingredients would include:
• Ephedrine – a stimulant that commonly found in weight-loss products and decongestants. There are studies raising concern and issues about its effects on the heart.
• Taurine – a natural amino acid needed by the body to help regulate heart beat and muscle contractions. Currently, researchers are trying to discover its impact as a energy drink additive.
• Ginseng – a kind of root thought to have several medicinal benefits. It is said that ginseng relives stress and can increase your level of energy.

• Vitamin B – a group of vitamins that can change sugar to energy
• Carnitine – an amino acid. Its effects can be mainly on the metabolism of fatty acids in the body.
• Creatine – an organic acid which main contribution is on energizing the muscles for muscle contraction.
• Inositol – a member of the vitamin B complex that helps relay messages within cells in the body.
• Ginkgo biloba – came from the seeds of the ginkgo biloba tree. There are studies claiming its memory enhancement capabilities. ¬
Caffeine is also present in most energy drinks. So how does an energy drink work? Caffeine and other minerals blocks certain brain chemicals in sending its messages to the brain. This brain chemical is called adenosine which mainly involved in sleep. Thinking that the body is experiencing a problem, the pituitary gland releases adrenaline.
Adrenaline release makes the heart beat faster, eyes to dilate, and the liver to release extra sugar to the mainstream. This would provide the consumer an extra surge of energy needed for intense physical or mental activity.
Like any other food, drink or drugs, too much is never good for you. Consuming too much energy drinks can lead to heart palpitations, anxiety, insomnia, irritability and even being jittery.
It is also dangerous to drink water while doing some exercise, since its effects are more leaned into dehydrating your body. There are also some people who mix energy drinks with alcohol. Studies showed that mixing alcohol and energy drinks would make you feel alert and sober, making you unaware of how much you actually drank. This could also lead to excessive drinking and later on to dehydration.
If you drink energy drinks, then be aware of how you consume it. There are some energy drinks that have instructions, be sure to follow them. Avid drinking too much of is, make sure to limit consumption to 2 cans a day. It is for the best to avoid mixing energy drinks to alcohol. When doing intense physical activity like exercise, then it would be best to just drink water instead. For pregnant women and young children, drinking energy drinks is best to be avoided. They also pose problems for those who have high blood pressure and heart disease.
Energy drinks can provide and be a health drink, as long as it consumed moderately.

New Program Offers Personalized Physician-assisted Approach To Losing Weight
Perhaps the only thing harder than sticking to a weight loss plan is starting a new one after yet another failed diet attempt. Physicians Sharon Herring and Stephanie Ward recognize such “diet fatigue” in their patients and their own families. Now, they’re offering a “fresh start” to the diet-weary.
Temple’s “Fresh Start to a Healthy Weight,” is designed to promote healthy behaviors such as physical activity and better food choices and prevent and treat adult obesity through one-on-one counseling. An extension of the General Internal Medicine Practices at Temple, the program opens in July.
“We know that when patients engage with providers who are solely focused on weight loss issues, they lose weight so that’s what we plan to do,” said Sharon Herring, MD, MPH, Assistant Professor of Medicine and Public Health at Temple University’s Center for Obesity Research and Education.
Herring and Ward are committed to getting to know each patient’s clinical status and concerns and will create an individualized care plan through a combination of:
Behavior modification focusing on caloric restriction and physical activity Cognitive therapy identifying and modifying distorted thinking about food, activity, and body image Weight loss medications as an adjunct to participant efforts.
Ward, a practicing general internist at Temple University Hospital, predominantly serves minorities of lower socioeconomic status, a population disproportionately affected by obesity. Study after study confirms that weight related diseases, like diabetes and hypertension, can be prevented or delayed with aggressive weight management, even if the weight loss is modest.
“You don’t have to be a size zero to start seeing the benefits of losing weight,” said Ward, Assistant Professor of Medicine and Public Health at the School of Medicine. “You may have diabetes or arthritis, but if you lose weight, you may be able to reduce the effects of those diseases. Even losing just five to ten percent of body weight improves your health and quality of life.”
The challenge is getting patients to change their behavior and feel satisfied with less. While exercise is important, Herring and Ward say diet and calories trump that when it comes to weight loss. Many of their patients know the calorie-rich foods they eat or sodas they drink aren’t good for them, but they admit they enjoy the taste. It will be up to both physicians to teach them how to make healthy food just as delicious and opt for the produce aisle at the grocery store instead of the drive-thru lane at a fast food restaurant.
“We may even take patients to the market to look at food labels, increase their awareness of what’s in processed foods and how to shop for truly healthy foods,” said Herring.
Both physicians agree that one-on-one interventions are missing during primary care visits, just as behavior change to address obesity is absent from medical school curriculum. They hope this program will change that by eventually offering fourth year medical students a chance to earn elective rotation credits, while facilitating training about obesity prevention and management for all residents.
“We empathize with the struggle and while we may not have all the answers, we will help our patients to come up with solutions that work ” say both Herring and Ward.
“Fresh Start to a Healthy Weight” opens July 6, 2009 in the ground floor of Jones Hall, 1316 W. Ontario Street (in the Internal Medicine Faculty Practice).
