High Fructose Corn Syrup

    Lately, there has been a lot of discussion—within the medical community as well as across the kitchen table—about the supposed harmful effects that high fructose corn syrup (HFCS) has on the human body. Many people wonder if its use as a sweetener is contributing to the population’s overall rate of obesity.

In the late 1970s, many of the largest food manufacturers in the United States shifted away from using refined table sugar to using the much cheaper HFCS. Soon HFCS was used to sweeten many products including cereal, steak sauce, soft drinks, bread, baked beans, and yogurt.

Table sugar and HFCS share a similar biochemical structure: both contain the simple sugars glucose and fructose, though HFCS is produced from corn and undergoes additional processing to increase the amount of fructose.

The American Medical Association does not take the view that one sweetener is better or worse than another. However, researchers at Princeton University have recently released a study showing that rats who consumed HFCS gained more weight, especially in the abdominal area, than rats who consumed table sugar.3

Other medical professionals say that more research is needed before conclusive results can be drawn. Meanwhile, nearly everyone can agree that both table sugar and HFCS are high in calories—nearly 50 per tablespoon —and that neither form of sweetener provides any measurable nutritional value.

Question: Choose the best summary of the passage.

Hypertension

     The term hypertension is used to describe the condition of chronically high blood pressure. People who are obese, experience a lot of stress, smoke tobacco products, have a diet with too much salt in it, or have diabetes are often at a higher risk for hypertension. As well, African Americans are more likely to have hypertension than other population groups.

Hypertension often develops over many years. Older people are most often diagnosed with hypertension. One reason for this is that blood vessels lose elasticity and stiffen as a person ages. This creates more resistance to the blood flowing through the body and elevates blood pressure.

Symptoms of hypertension can include blurred vision, headaches, a buzzing in the ears, fatigue, an irregular heartbeat, and nosebleeds. Hypertension that goes untreated over a period of time can lead to serious complications such as kidney disease, heart disease, loss of vision, heart attack, brain damage, and even early death. Fortunately, treating hypertension reduces blood pressure and can lower the risk of complications. For many people, losing weight can result in a significant decrease in blood pressure. For others, physicians may prescribe one or more medications to help bring blood pressure down into a safe range.

One thing is certain: physicians believe that people over the age of 20 should monitor their blood pressure by having it checked at least once a year. Those with a history of hypertension in the immediate family should have it checked more frequently.

• What does the term elasticity mean, as used in the second paragraph?

Concussion

  A concussion is a traumatic injury to the brain that can interfere with the way the brain processes information and functions. A concussion often results in severe headaches, diminished alertness, and even unconsciousness.

While more than one million people in the United States suffer concussions every year, many believe that, like people, no two concussions are identical. Recently two professional baseball players suffered concussions. The first player was injured early in the season and tried twice to return to regular play, but was not medically cleared to play until the following year. Even after eight months, this player reported a recurring condition of “fogginess” that seemed to linger. The second player had brief symptoms of sleepiness and involuntary movement, or “shakiness.” A few days later, and after several tests, the second player reported that the effects of the concussion had subsided, and he was cleared to play.

No matter the duration of a person’s recovery, refraining from trying to do too much, too soon is vital. A specialist at Boston University’s Center for the Study of Traumatic Encephalopathy believes that someone who suffers a second concussion while still recovering from the first risks an even longer recovery.

Full recovery from concussions is possible. Problems are seldom permanent, and for most people who have had a concussion, the long-term prognosis is typically excellent. The first baseball player recently returned to his team. And though he was told by his physician that he has no greater risk than anyone else of suffering another concussion, other physicians believe that suffering one sports-related concussion increases the likelihood of suffering another.

Sickle-Cell Anemia

     Healthy red blood cells are shaped like a disc. Each cell contains the protein hemoglobin, which carries oxygen throughout the body. In some people, a crescent-shaped cell forms instead of the normal disc-shaped cell. The crescent-shaped cells contain abnormal hemoglobin. These sickle-shaped cells are fragile and are unable to carry oxygen properly throughout the body.

Sickle-cell anemia is an inherited disease that affects about 72,000 people in the United States. It is more common among people of South American or African descent. The genes for sickle-cell anemia are inherited from both parents. When both parents carry a gene for the trait for sickle- cell, there is a one in four chance that they will pass the disease on to their children.

Symptoms of sickle-cell anemia can include sudden occurrences of extreme abdominal and back pain, bone pain, fever, fatigue, and a rapid heart rate. One patient compared the pain in his back to a jackhammer and said the pain could take over his entire body. Another patient, an eight-year- old girl, described fevers and the feeling of someone squeezing her arms and legs.

Cycles of symptoms are often unpredictable and can occur infrequently or almost constantly. Some people who are affected report weekly occurrences of persistent pain, while others report occurrences once a month. Some report that relief comes only by using powerful painkillers. For others, relief comes with bed rest and a hot-water bottle. Most agree that while the challenges of managing sickle-cell anemia are great, with diligent care, it can be managed.

Toxins and Your Health

    Lie out in the sun too much today—and get skin cancer 20 years from now. Smoke too many cigarettes now—and get lung cancer decades down the road. Now there is potentially a third danger to add to this list: be exposed to too much lead, pesticides, or mercury now and have your aging brain become seriously confused during your senior years.

“We’re trying to offer a caution that a portion of what has been called normal aging might in fact be due to ubiquitous environmental exposures like lead,” says Dr. Brian Schwartz of Johns Hopkins University. “The fact that it’s happening with lead is the first proof of the principle that it’s possible.”

A new area of medical research is one that studies how exposure to toxic elements in younger years can result in serious health problems in senior years. It is difficult to research these problems because the only way to do so is to observe people over many years.

Physicians test for lead amounts by seeing how much has accumulated in a person’s shinbone. Testing the blood also often reveals amounts of lead, but that is a sign of recent, not lifelong, exposure. The higher the lifetime lead dose, according to the study, the worse the performance of mental functions, including verbal and visual memory and language ability.

Yoga

      Yoga is an exercise that everyone should try. Yoga was first practiced thousands of years ago. It helps connect the mind and body by taking a person through a series of poses while emphasizing controlled breathing and meditation. Every year hundreds of thousands of people enjoy the benefits of yoga by treating the movements and postures as exercise. Yoga works by safely stretching muscles, ligaments, and tendons. This helps release the buildup of lactic acid in the muscles that can often cause stiffness, tension, and even pain. Yoga helps develop the body’s range of mobility and increases the ease of everyday movements. Many participants report improved flexibility, especially in the trunk and shoulders, after only two months of practice. Yoga improves posture, balance, and sleep, and it also helps with weight control.

Physically, many yoga poses help build upper-body strength, which is increasingly important as the body ages. Other poses help strengthen the muscles in the lower back, and when properly practiced, nearly all of the poses strengthen the body’s abdominal, or core, muscles. This helps improve the circulation of blood that increases the delivery of nutrients and oxygen to the body and also removes wastes produced by the body. When combined with yoga’s benefit of lowering a person’s heart rate, the result is increased cardiovascular endurance.

The University of Maryland School of Nursing recently published a study that showed yoga was especially effective at reducing stress. In addition, researchers found that yoga surpassed traditional aerobic exercise, often significantly, in improving flexibility, pain tolerance, and daily energy levels. One enthusiast says that her advice to skeptics is simple, “Take a deep breath, stretch, and indulge in a few poses. You’ll feel better.”

Every year hundreds of thousands of people enjoy the benefits of yoga by treating the movements and postures as exercise. Yoga works by safely stretching muscles, ligaments, and tendons. This helps release the buildup of lactic acid in the muscles that can often cause stiffness, tension, and even pain. Yoga helps develop the body’s range of mobility and increases the ease of everyday movements. Many participants report improved flexibility, especially in the trunk and shoulders, after only two months of practice. Yoga improves posture, balance, and sleep, and it also helps with weight control.

Physically, many yoga poses help build upper-body strength, which is increasingly important as the body ages. Other poses help strengthen the muscles in the lower back, and when properly practiced, nearly all of the poses strengthen the body’s abdominal, or core, muscles. This helps improve the circulation of blood that increases the delivery of nutrients and oxygen to the body and also removes wastes produced by the body. When combined with yoga’s benefit of lowering a person’s heart rate, the result is increased cardiovascular endurance.

The University of Maryland School of Nursing recently published a study that showed yoga was especially effective at reducing stress. In addition, researchers found that yoga surpassed traditional aerobic exercise, often significantly, in improving flexibility, pain tolerance, and daily energy levels. One enthusiast says that her advice to skeptics is simple, “Take a deep breath, stretch, and indulge in a few poses. You’ll feel better.”
