SLEEP:
Most people get a little grumpy when they do not get enough sleep, but for children, the issue may extend beyond mere irritability. Lack of sleep can affect their weight and overall behavior. A study conducted in New Zealand at the University of Auckland and published in the medical journal Sleep followed almost 600 children from infancy through seven years of age. Researchers observed the children�s sleep patterns and found that they generally slept less on weekends than during the week, and even less during the summer months.
According to the findings, children who slept the least were at a greater risk for being overweight and experiencing behavioral problems. Those who regularly slept less than nine hours a night were three times more likely to be obese and to show signs of attention deficit disorder (ADD) and attention deficit hyperactivity disorder (ADHD) compared to those who slept more. These results were based on questionnaires completed by the children�s parents and teachers.
The connection between sleep and weight is still not fully understood, but experts suspect that chronic sleep deprivation may alter hormones involved in appetite control and metabolism. This is a connection that needs further exploration to be fully understood.
Experts recommend that preschoolers get 11 to 13 hours of sleep each night, while school-age children should get between 10 and 11 hours per night. However, many children average only 8 hours of sleep. The study concluded that adjusting sleep duration is a manageable risk factor that can help prevent future health problems for today�s young people.

What conclusion can a reader draw about the connection between sleep and young children?

• A. Lack of sleep causes children to fail in school.
• B. Inadequate rest raises the risk of behavioral and physical problems.
• C. Sleeping less than 10 hours a night is guaranteed to result in obesity.
• D. Eight hours of sleep each night meets the requirements of most children.

Lifewings Partners:
What do pilots, astronauts, physicians, and risk managers have in common? In this case, they are all part of Lifewings Partners, an organization based in Memphis, Tennessee, dedicated to eliminating mistakes and accidents in medical settings across the United States.
Lifewings Partners highlights the need for vigilance in medical environments. According to the Institute of Health, approximately 98,000 patients die each year in U.S. healthcare settings due to medical errors. Examples of such errors include a man who had the wrong testicle removed in a Los Angeles hospital, a young boy who suffered brain damage from anesthesia during a routine hernia surgery, and a hospital in Rhode Island that performed brain surgery on the wrong side of the brain on three different patients in less than a year.
To combat these issues, Lifewings Partners not only advocates for internal changes in medical procedures and the establishment of checklists but also focuses on patient education. They recommend that consumers research a hospital’s safety record online, discuss safety standards with their doctors, and inquire about facilities with the best safety records.
Founder Steve Harden emphasizes, “Just because a hospital has a great reputation for cutting-edge medicine doesn’t necessarily mean the hospital is the safest place to go for routine procedures.” He warns that some mistakes are too significant and irreversible to risk, underscoring the importance of careful selection and preparation in healthcare settings.

Which statement could be inferred by the reader from the last paragraph of the passage?

• A. Procedures that Lifewings Partners recommends are always effective.
• B. Medical mistakes can happen at even the best hospitals.
• C. City hospitals know more than others about cutting-edge medicine.
• D. Medical mistakes will one day be completely eradicated.

THE FOOD PYRAMID:
The food pyramid is a visual representation of how the different food groups can be combined to form a healthy diet. Although it was a vital part of dietary guidelines for years before being replaced by the �MyPlate� model, the pyramid was constantly analyzed and revised as additional study was done in nutritional fields. A few years ago, the pyramid underwent a change regarding the unique dietary needs of seniors.
Modifications in the pyramid for older adults included an emphasis on fiber and calcium, as well as on vitamins D and B12. By incorporating these changes, the pyramid indicated that the nutrients found in a person�s routine daily consumption typically are not enough for seniors. Seniors need supplementation. As people age, they tend to move less and thus need fewer calories to maintain their weight. Because seniors tend to eat a more limited amount, dietitians urge them to choose wisely. They are encouraged to eat nutrient-rich meals featuring such foods as fruits, vegetables, low-fat dairy products, and high-fiber whole grains.
The revised pyramid also focused on the importance for older people of ingesting adequate amounts of fluids daily. This helps to ensure proper digestion and prevent dehydration. Finally, the revised pyramid included information on incorporating exercise and other physical activities into the lives of older adults. Suggestions included swimming, walking, or simple yard work. With recent reports indicating that obesity levels for people older than 70 years of age are climbing, performing some type of regular exercise is more essential than ever.

What is the meaning of the word supplementation as used in the second paragraph?

• A. Extra
• B. Organization
• C. Attachment
• D. Revision

FAT IN A HEALTHY DIET:
After years of bad publicity, it may sound absurd, but many dietitians are now extolling the virtues of consuming fat. According to Laurie Tansman, a nutritionist at Mt. Sinai Medical Center in New York, fat "not only plays a vital role in the health of the membrane of every cell in our body, it also helps protect us from a number of key health threats." Fat is a critical part of your necessary food intake, with a general recommendation that 30 percent of your daily calories should come from fat. Without it, your body would not be able to absorb or transport vitamins A, D, E, and K. Additionally, body temperature, hair follicles, and skin cells all rely on the consumption of fats to function properly.
There is near-universal agreement that the healthiest fats are unsaturated fats. This category includes olive oil, sesame oil, walnut oil, avocado oil, and omega-3 fatty acids. When consumed in moderation, these fats can lower cholesterol levels, thereby reducing the risk of heart disease. Saturated fats, while not as healthy as unsaturated fats, should still be consumed more sparingly. These fats are commonly found in animal products such as beef, pork, and chicken.
The least healthy of all fats are trans-fatty acids, or trans fats. Though trans fats can occur naturally in small amounts in animal products, they are more commonly found as artificially produced oils used for frying foods or softening prepackaged snacks. These fats increase the risk of heart disease, and the U.S. Dietary Guidelines recommend consuming as few trans fats as possible.

Choose the best summary of the passage.

• A. We often think of all fat as bad, but it is clear that certain fats, especially the more healthful unsaturated fats, are important for bodily function.
• B. If you must consume some fat, be sure to choose unsaturated fats such as oils rather than saturated fats found in prepackaged snacks or animal products.
• C. Doctors and researchers have discovered that without the calories found in fat, people would not have functioning metabolisms.
• D. Some intake of saturated fat is necessary, but you should stay away from the kind of fat found in fried food, which can lead to heart disease.
