Food away from home (FAFH) has been associated with poor diet quality in many studies. It is difficult, however, to measure the effect of FAFH on diet quality since many unobserved factors, such as food preferences and time constraints, influence not just our choice of where to eat, but also the nutritional quality of what we eat. Using data from 1994-96 and 2003-04, this study applies fixed- effects estimation to control for such unobservable influences and finds that, for the average adult, FAFH increases daily caloric intake and reduces diet quality. The effects vary depending on which meals are consumed away from home. On average, breakfast away from home decreases the number of servings of whole grains and dairy consumed per 1,000 calories and increases the percent of calories from saturated and solid fat, alcohol, and added sugar (So FAAS) in a day. Dinner away from home reduces the number of servings of vegetables consumed per 1,000 calories for the average adult. Breakfast and lunch away from home increase calories from saturated fat and So FAAS on average more among dieters than among non-dieters. Some of the overall negative dietary effects decreased between 1994-96 and 2003- 04, including those on whole grain, sodium, and vegetable consumption. Which meal(s) eaten away from home have worse results for dieters than for non-dieters? • The article doesn’t state which meal is the worse for non-dieters • Dinner eaten away from home is worse because people consume fewer whole grains and vegetables. • Breakfast eaten away from home is worse because it increases the percent of calories from saturated and solid fat, alcohol, and added sugar (So FAAS) in a day. • Breakfast and lunch eaten away from home are worse because they increase the percent of calories from saturated fats. Why is it difficult to measure the effect of food away from home on diet quality? • People eat out too much, so it is not possible to collect accurate data. • Researchers are unable to assess the nutritional quality of people’s diets. • Peoples’ food preferences are too complex and may even be unmeasurable. • Too many unknown variables affect the data. Which statement is not a detail from the passage? • Eating breakfast away from home can result in an increase in fatty protein consumption. • Eating food away from home is connected to bad food choices. • In general, people who eat breakfast away from home consume more calories. • Eating dinner away from home results in less vegetable consumption. What is the meaning of the word “associated” in the first paragraph? • Specialized • Predated • Connected • Obfuscated A nanometer is a billionth of a meter. A DNA molecule is 2 nanometers in diameter. Protein molecules are about 10 nanometers in diameter. A human hair is 100,000 nanometers in diameter. But what is a nanometer and how does it relate to technology? Nanotechnology is defined as the understanding and control of matter at dimensions of roughly 1 to 100 nanometers, a scale at which unique properties of materials emerge that can be used to develop novel technologies and products. At the nanoscale, the physical, chemical, and biological properties of materials differ from the properties of matter either at smaller scales, such as atoms, or at larger scales that we use in everyday life such as millimeters or inches. Nanotechnology involves imaging, measuring, modeling, and manipulating matter only a few nanometers in size. Gold nanoparticles are made of the same material as in jewelry. But when light interacts with particles of gold, different colors are reflected. The different colors can be used in simple medical tests to indicate infection or disease. Metals such as copper become extremely rigid at the nanoscale, rather than bendable as in copper wires seen in everyday use. What is the major difference between matter at the nanoscale and matter at larger scales such as millimeters or inches? • At the nanoscale, metals are bendable, and at larger scales they are rigid. • Matter has different and special characteristics at the nanoscale. • At the nanoscale, matter has the same properties as matter at the atomic level. • There is no difference. Which claim from the passage best describes the benefits of nanotechnology? • Scientists can develop novel technologies and products. • Nanotechnology is defined as the understanding and control of matter at dimensions of roughly 1 to 100 nanometers. • The different colors can be used in simple medical tests to indicate infection or disease. • Unique properties of materials emerge. What is the author’s primary purpose in writing this essay? • To explain how to utilize the nanoscale • To review the conversion between the nanoscale and nanotechnology • To advocate for the usage of more nanotechnology • To describe nanotechnology and what it is
