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.

What is the meaning of the word diligent as used in the last paragraph about Sickle-Cell Anemia?

• A. Dispersed.
• B. Incensed.
• C. Painstaking.
• D. Demanding.

SUPER FOODS:
Super foods are whole, unprocessed foods such as blueberries, walnuts, beans, oats, and broccoli. Spinach, yogurt, and pomegranates are also considered super foods. They are classified as such because they contain high levels of essential nutrients, are low in calories, and can often help prevent—and even reverse—some of the common effects of aging including cardiovascular disease, type 2 diabetes, high blood pressure, and certain types of cancer. Super foods help lower cholesterol levels in the blood and, some researchers believe, even improve a person’s mood.
High on the list of super foods are blueberries, fresh or frozen, which are loaded with vitamin C, antioxidants, and potassium. Blueberries are also an anti-inflammatory, which many researchers and nutritionists believe is beneficial. Lentils are a super food that helps prevent a spike in insulin levels that can increase body fat. Lentils are high in both fiber and protein, each of which contributes to stabilizing blood sugar levels and reducing excess fat, especially in the stomach area. Walnuts are a plant-based source of essential unsaturated omega-3 fatty acids, which can improve cholesterol and lower the risk of heart disease by as much as 50 percent.
All oats are healthful. Oats, even instant oatmeal, are digested slowly while providing up to five grams of fiber per serving. As physicians and nutritionists continue to study super foods and their effects, consumers continue to educate themselves about the variety of benefits. In an era when consumers question the origin and nutritional value of much of the food on store shelves, super foods are some of the most healthful and natural whole foods available.

Which statement would not be inferred by the reader in the passage about Super Foods?

• A. Instant oatmeal can be part of a healthful breakfast.
• B. Blueberries are an especially healthful food.
• C. Certain grains and dairy products are super foods.
• D. Super foods are more expensive than processed foods.

SLEEP:
Developing muscle growth is an effective way to stay healthy as we get older, but many people find it difficult to develop this muscle growth, even after modifying their exercise routine and food intake. What many people may not realize is that getting the proper amount of uninterrupted sleep plays a major role in the development of muscle. The hard work of developing muscle is done in the gym, on a track, or on the court, but the actual growth takes place during the rest periods that follow a workout. Your body immediately begins rebuilding the muscle fibers that were broken down during the course of your workout. Much of this process is carried out while you are sleeping, so without a full night of sleep, muscle fibers will not have the opportunity to rebuild.
Human growth hormone (HGH) is an amino acid that is central to regulating metabolism, building muscle, facilitating calcium retention, and stimulating the immune system. The amount of HGH in your body spikes significantly during deep sleep, which makes getting at least 7 to 10 hours of sleep every night imperative to anyone hoping to develop additional muscle growth. Recent studies have linked inadequate amounts of sleep to lowered levels of leptin, a hormone in the brain that controls appetite. Test subjects who received less sleep, or frequently interrupted sleep, would crave carbohydrates even after their caloric needs reached satiety. This can contribute to obesity and negatively affect any good habits people may have developed with regard to food intake.

What is the meaning of the word satiety as used in the last paragraph about The Sleep Workout?

• A. A state of tiredness.
• B. A state of being satisfied.
• C. A state of being overloaded.
• D. A state of confusion.

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.”

Which of the following is not listed as a detail in the passage about Yoga?

• A. Improved circulation.
• B. Strengthening of core muscles.
• C. Stress reduction.
• D. Fortification of immune system.

HCFS:
The impact of high fructose corn syrup (HFCS) on health has been a topic of concern in recent years. High fructose corn syrup, a sweetener derived from corn, has been linked to various health issues, including obesity. Unlike refined table sugar, which is a natural product, HFCS is manufactured through a chemical process. Studies have shown that rats tend to prefer HFCS over other sweeteners, raising questions about its effects on human health. The American Medical Association (AMA) has examined the implications of HFCS consumption and its potential role in the obesity epidemic. Despite some benefits in terms of cost and versatility in food products, the association has highlighted potential health risks, including increased caloric intake and potential links to obesity. As research continues, the debate over the safety and health implications of HFCS remains relevant.

Which of the following is not mentioned as a detail in the passage about High Fructose Corn Syrup?

• A. HFCS and sugar share a biological structure.
• B. HFCS is cheaper to use than sugar.
• C. HFCS is now used to sweeten a variety of products.
• D. HFCS contains more calories than aspartame.
