질문 # 82
The body requires energy to process food through digestion, absorption, transportation, metabolism and storage. This requirement represents_____________% of daily energy (calorie) intake.
정답：D
설명：
The body expends a portion of its daily energy intake on the process of digesting, absorbing, transporting, metabolizing, and storing the food we consume. This energy expenditure is known as the Thermic Effect of Food (TEF), also sometimes referred to as dietary-induced thermogenesis.
TEF represents the increase in metabolic rate after ingestion of a meal, and it varies depending on the composition of the meal; for instance, proteins usually have a higher thermic effect compared to carbohydrates and fats. On average, the TEF accounts for approximately 10% of the total daily energy expenditure. This means that if an individual consumes 2000 calories in a day, about 200 of those calories will be utilized simply for processing the food eaten.
To calculate the total daily energy needs, one must consider not only the basal metabolic rate (BMR), which is the energy expended at rest to maintain vital body functions, but also the energy used in physical activity and the TEF. The formula to adjust BMR for TEF involves multiplying the BMR by 0.10 - reflecting the 10% average TEF - and then adding this value back to the BMR before incorporating activity levels. This adjusted figure provides a more accurate estimation of total daily energy needs, ensuring that dietary recommendations meet the individual's true energy requirements.
Understanding this component of energy expenditure is crucial for devising precise dietary plans, particularly for weight management strategies. By accounting for the energy used in food processing, individuals can better gauge their net caloric intake and make informed decisions about their eating habits and activity levels.
질문 # 83
Water-soluble vitamins include which of the following?
정답：B
설명：
Water-soluble vitamins are a category of nutrients that dissolve in water and are readily absorbed into tissues for immediate use. Unlike fat-soluble vitamins, which are stored in the body's fatty tissue, water-soluble vitamins are not stored in the body in significant amounts. As a result, they need to be replenished regularly through the diet to avoid deficiencies.
The primary water-soluble vitamins include the B-complex vitamins and vitamin C. The B-complex group consists of several vitamins such as thiamine (B1), riboflavin (B2), niacin (B3), pyridoxine (B6), and cobalamin (B12). Each of these vitamins plays a crucial role in energy production, maintaining proper nerve function, and the production of red blood cells. Thiamine, for example, is essential for aerobic metabolism, riboflavin aids in energy production, niacin is vital for DNA repair, and vitamin B6 is important for protein metabolism.
Vitamin C, also known as ascorbic acid, is another important water-soluble vitamin. It is necessary for the synthesis of collagen, which helps maintain skin, blood vessels, bones, and cartilage. Vitamin C also serves as a powerful antioxidant, helping to protect cells against damage by free radicals and supporting the immune system.
Since water-soluble vitamins are not stored in the body, they are generally considered safe at recommended dosages as any excess is flushed out in the urine. However, it is important to maintain a regular intake because the body does not have a large reserve to draw upon when dietary intake is inadequate. This rapid turnover rate explains why deficiencies can quickly develop if dietary intake is insufficient. Common symptoms of such deficiencies might include skin disorders, cracks in the lips, dry hair, or more serious conditions such as anemia or neurological impairments.
Taking a daily supplement, such as a B-complex, can be beneficial in ensuring adequate intake of these essential nutrients, particularly for individuals who may not get enough from their diet alone. This is especially relevant for those who follow vegetarian or vegan diets, as some B vitamins, particularly B12, are primarily obtained from animal sources. Regular intake of these vitamins is crucial to avoid the rapid onset of deficiencies and to support overall health.
질문 # 84
When pureeing food, what happens to the volume of fruits and vegetables?
정답：D
설명：
When pureeing fruits and vegetables, the volume of the produce decreases. This occurs because the process of pureeing breaks down the fibrous structures and cells within the fruits and vegetables, releasing trapped air and reducing the overall space they occupy. Additionally, during pureeing, any excess water contained within the produce may also be released, which contributes to a reduction in volume.
The result of pureeing is a more compact, smoother texture that appears to occupy less space than the original whole fruits or vegetables. Despite this decrease in volume, the nutritional content of the fruits and vegetables remains, making the puree more nutrient-dense per spoonful compared to the raw, whole form. This is beneficial for creating concentrated flavors and nutrients in meals, especially in dishes where space and texture are considerations, such as smoothies or soups.
It's important to note that this characteristic of decreasing volume is specific to fruits and vegetables. In contrast, when meats are pureed, the volume can actually increase. This is because meats generally require the addition of liquids, such as water or broth, to facilitate the pureeing process and achieve a palatable texture. This addition of liquid increases the overall volume of the pureed meat compared to its original form.
질문 # 85
When counseling a client on nutrition and smart eating behaviors, they should include all of the following except:
정답：C
설명：
When counseling a client on nutrition and smart eating behaviors, several effective strategies should be included. However, not all suggestions may be beneficial or appropriate depending on the context. Let's explore these strategies and identify which one should not be included.
One smart eating behavior is to pause in the middle of the meal. This pause helps the individual assess their current level of fullness and can prevent overeating by allowing the brain time to register the amount of food that has been eaten. This moment of reflection is a mindful eating practice that can significantly contribute to better eating habits.
Another recommended practice is to focus solely on eating during mealtime, meaning avoiding distractions like reading or watching television. This practice helps the individual to be fully present during the meal, which can enhance the awareness of the body's cues on hunger and satiety and prevent mindless eating, which often leads to consuming more calories than needed.
Soliciting help from family and friends can also be very beneficial. When someone is trying to change their eating habits or improve their nutrition, having a support system can be crucial. Family and friends can provide emotional support, encouragement, and even practical help, such as sharing healthy recipes or joining in healthier meal preparations. They can also be part of a reward system to reinforce good eating behaviors, offering praise or agreed-upon rewards for reaching certain goals.
Therefore, the advice to "do not solicit help from family and friends" would be the incorrect choice and should not be included in counseling for smart eating behaviors. Having a support network can make the journey toward better health more enjoyable and sustainable. This support can be instrumental in maintaining motivation and ensuring compliance with new eating practices.
In summary, while pausing during meals and avoiding distractions like TV or reading during meals are beneficial practices, the recommendation to avoid seeking help from family and friends is not advisable. On the contrary, encouraging clients to engage their support networks can greatly enhance their success in adopting healthier eating behaviors.
질문 # 86
In adults, which of the following would be considered a normal glomerular filtration rate (GFR)?
정답：B
설명：
The Glomerular Filtration Rate (GFR) is a critical measure used to assess the functioning of the kidneys. It represents the volume of fluid filtered from the renal glomerular capillaries into the Bowman's capsule per unit time. Essentially, GFR indicates how well the kidneys are filtering the blood.
In healthy adults, a normal GFR ranges from approximately 90 to 120 ml/min. This range can be influenced by various factors including age, sex, body size, and health status. The GFR decreases naturally with age, and values may be lower in women compared to men due to generally having less muscle mass.
Given the options presented: - A GFR of less than 60 ml/min suggests potential kidney dysfunction and may warrant further investigation by healthcare professionals. This level could indicate mild to moderate kidney damage. - A GFR of 65 ml/min, though closer to the normal range, is still considered below optimal and could suggest mild kidney impairment. - A GFR of 85 ml/min is also below the normal range but closer to what might be expected in early kidney decline or in older adults. - A GFR of 110 ml/min falls well within the normal range, indicating healthy kidney function.
Therefore, among the options provided, a GFR of 110 ml/min would be considered a normal and healthy rate for adults. Maintaining a GFR within this range suggests that the kidneys are effectively filtering wastes and excess fluids from the blood, contributing to overall good health. Regular monitoring of GFR is essential, especially for individuals with risk factors for kidney disease, to ensure kidney health is maintained over time.
