    The basic building block of a protein is called a(n) 

    • Monosaccharide

    • Keto acid

    • Amino acid

    • Fatty acid

    Correct Answer
    A. Amino acid
    Explanation
    Amino acids are the basic building blocks of proteins. Proteins are composed of long chains of amino acids that are linked together by peptide bonds. Each amino acid consists of an amino group, a carboxyl group, and a unique side chain. These side chains give each amino acid its specific properties and determine how it interacts with other amino acids in a protein. Therefore, amino acids are essential for the structure and function of proteins in living organisms.

    Body weight in kilograms divided by height squared in meters yields 

    • The obesity index.

    • Relative weight.

    • Body mass index.

    • Percent body fat.

    Correct Answer
    A. Body mass index.
    Explanation
    The body mass index (BMI) is calculated by dividing body weight in kilograms by height squared in meters. This index is used to assess whether a person has a healthy body weight in relation to their height. It provides a standardized measurement that can be used to determine if an individual is underweight, normal weight, overweight, or obese. The BMI is commonly used in medical and health fields as a quick and easy way to screen for potential weight-related health issues.

    Which of the following contains a rich supply of omega-3 fatty acids? 

    • Sirloin

    • Chicken

    • Broccoli

    • Salmon

    Correct Answer
    A. Salmon
    Explanation
    Salmon contains a rich supply of omega-3 fatty acids. Omega-3 fatty acids are essential fats that our body needs for various functions, including brain health and reducing inflammation. While sirloin and chicken are good sources of protein, they do not contain significant amounts of omega-3 fatty acids. Broccoli is a nutritious vegetable but does not contain omega-3 fatty acids in high quantities. Therefore, the correct answer is salmon, as it is known to be a great source of omega-3 fatty acids.

    Constipation can best be prevented by 

    • Restricting fluids.

    • Using laxatives.

    • Engaging in little physical exercise.

    • Eating dietary fiber.

    Correct Answer
    A. Eating dietary fiber.
    Explanation
    Eating dietary fiber helps prevent constipation because it adds bulk to the stool, making it easier to pass through the digestive system. Fiber also helps regulate bowel movements and promotes healthy digestion. Restricting fluids can actually worsen constipation, as dehydration can lead to harder and more difficult-to-pass stools. Laxatives may provide temporary relief, but they should not be relied upon as a long-term solution as they can cause dependence and may have side effects. Engaging in little physical exercise can also contribute to constipation, as exercise helps stimulate bowel movements.

  • 6. 

    Where does digestion begin? 

    • Small intestine

    • Mouth

    • Stomach

    • Esophagus

    Correct Answer
    A. Mouth
    Explanation
    Digestion begins in the mouth. This is where the process of breaking down food starts, as the teeth chew and grind the food into smaller pieces. Saliva is also produced in the mouth, which contains enzymes that begin the chemical breakdown of carbohydrates. The partially digested food then travels down the esophagus into the stomach, where further digestion takes place. However, the initial breakdown of food occurs in the mouth.

    Rate this question:

  • 7. 

    The muscular contractions that move food through the digestive tract are called 

    • Peristalsis

    • Compression

    • Propulsion

    • Regurgitation

    Correct Answer
    A. Peristalsis
    Explanation
    Peristalsis refers to the wave-like contractions of the muscles in the digestive tract that propel food forward. These contractions help to move the food through the esophagus, stomach, and intestines, allowing for digestion and absorption of nutrients. Compression, propulsion, and regurgitation are not accurate terms to describe this specific movement of food through the digestive system.

    Which of the following is true about the way we should eat to achieve good nutritional status? 

    • Eat only plant products because animal products are bad and generally filled with hormones for animal growth

    • Eat fruits and vegetables because we can get all the nutrients we need from these

    • Eat a wide variety of foods because no single natural food meets all human nutrient needs

    • Do the best we can but take supplements to fill in the deficient areas

    Correct Answer
    A. Eat a wide variety of foods because no single natural food meets all human nutrient needs
    Explanation
    Eating a wide variety of foods is important to achieve good nutritional status because no single natural food can provide all the necessary nutrients that the human body needs. Different foods contain different nutrients, so consuming a diverse range of foods ensures that we get a balanced intake of vitamins, minerals, proteins, carbohydrates, and fats. This approach helps to prevent nutrient deficiencies and promotes overall health and well-being.

    Margaret, an elderly woman, needs to limit her kcalorie intake without sacrificing needed nutrients. Keeping in mind the Food Guide Pyramid, which of the following could she do? 

    • Eliminate carbohydrate

    • Count kcalories and not worry about the food groups

    • Eliminate Dairy foods.

    • Carefully select foods rich in nutrients but low in kcalories

    Correct Answer
    A. Carefully select foods rich in nutrients but low in kcalories
    Explanation
    Margaret, being an elderly woman, needs to limit her calorie intake while still getting the necessary nutrients. Eliminating carbohydrates or dairy foods entirely would not be a suitable option as they provide important nutrients. Counting calories without considering the food groups may lead to an imbalanced diet. Therefore, the best approach for Margaret would be to carefully select foods that are rich in nutrients but low in calories. This way, she can maintain a balanced diet while reducing her calorie intake.

  • 12. 

    Which of the following is true about the absorption, transport, and storage of fat-soluble vitamins? 

    • They are not stored to any great extent

    • After absorption, they are transported in the bloodstream to body cells and or stored in the liver and fatty tissue

    • They enter the bloodstream directly after absorption

    • Fat in the digestive contents is not important for their absorption

    Correct Answer
    A. After absorption, they are transported in the bloodstream to body cells and or stored in the liver and fatty tissue
    Explanation
    After absorption, fat-soluble vitamins are transported in the bloodstream to body cells and can be stored in the liver and fatty tissue. This is because fat-soluble vitamins dissolve in fat and are absorbed along with dietary fat. Once absorbed, they are transported through the bloodstream to various body cells where they are utilized. Any excess fat-soluble vitamins that are not immediately needed are stored in the liver and fatty tissue for later use.

    If a fat contains mostly saturated fatty acids, it is likely to be 

    • Solid at room temperature.

    • Soft at room temperature.

    • Rancid at room temperature.

    • Liquid at room temperature.

    Correct Answer
    A. Solid at room temperature.
    Explanation
    Saturated fatty acids have a straight molecular structure and tightly packed chains, which allows them to stack closely together. This results in a solid state at room temperature. In contrast, unsaturated fatty acids have kinks in their molecular structure due to double bonds, which prevents close packing and leads to a liquid state at room temperature. Therefore, a fat that contains mostly saturated fatty acids is likely to be solid at room temperature.

    The function of thick mucus in the stomach is to 

    • Promote fat digestion.

    • Protect stomach cells from acid and enzymes.

    • Activate stomach enzymes.

    • Keep the stomach bacteria-free.

    Correct Answer
    A. Protect stomach cells from acid and enzymes.
    Explanation
    The thick mucus in the stomach serves to protect the stomach cells from the corrosive effects of acid and enzymes. The stomach produces hydrochloric acid and various enzymes to aid in digestion, but these substances can also damage the stomach lining. The thick mucus layer acts as a barrier, preventing the acid and enzymes from directly contacting and harming the stomach cells. This protective function is essential for maintaining the integrity and health of the stomach.

    Salt is the correct answer because it is a common ingredient used in cooking and food preparation. It is also added to many processed foods to enhance flavor. Salt contains sodium chloride, which is a major source of chloride in the diet. While other foods like milk, nuts, and cheese may contain some chloride, they are not as significant of a source as salt.

    Rate this question:

  • 18. 

    Which of the following hormones corrects a hyperglycemic state? 

    • Insulin

    • Glucagon

    • Epinephrine

    • Cortisol

    Correct Answer
    A. Insulin
    Explanation
    Insulin is the correct answer because it is the hormone responsible for lowering blood glucose levels. In a hyperglycemic state, where blood sugar levels are too high, the body needs insulin to help transport glucose from the bloodstream into cells, where it can be used for energy or stored for later use. Insulin also inhibits the liver from producing more glucose. Therefore, the administration of insulin can effectively correct a hyperglycemic state by promoting glucose uptake and reducing blood sugar levels.

    Which of the following are substances in plant foods that are not digested in the stomach or small intestine? 

    • Dietary fiber

    • Dextrose

    • Disaccharides

    • Simple sugars

    Correct Answer
    A. Dietary fiber
    Explanation
    Dietary fiber refers to the indigestible parts of plant foods, such as fruits, vegetables, whole grains, and legumes. It passes through the stomach and small intestine largely intact and reaches the large intestine, where it undergoes fermentation by gut bacteria. This process provides various health benefits, including improved digestion, regulation of blood sugar levels, and maintenance of a healthy weight. Therefore, dietary fiber is not digested in the stomach or small intestine, making it the correct answer.

    What structure prevents food from entering the trachea when you swallow?

    • Esophagus

    • Tonsils

    • Epiglottis

    • Tongue

    Correct Answer
    A. Epiglottis
    Explanation
    The epiglottis is a flap of tissue located at the base of the tongue that prevents food from entering the trachea when you swallow. It covers the opening of the trachea, called the glottis, and directs food down the esophagus instead. This prevents choking and ensures that food goes into the stomach for digestion rather than entering the respiratory system. The esophagus, tonsils, and tongue do not have a direct role in preventing food from entering the trachea.

    One would be likely to see positive protein balance in all of the following conditions except 

    • Recovery from surgery.

    • Growth.

    • Starvation.

    • Pregnancy.

    Correct Answer
    A. Starvation.
    Explanation
    Positive protein balance refers to a state where the body is synthesizing more protein than it is breaking down. This occurs during periods of growth, pregnancy, and recovery from surgery, as these conditions require an increased amount of protein for tissue repair and growth. However, during starvation, the body lacks sufficient nutrients and energy, leading to a negative protein balance where protein breakdown exceeds synthesis. Therefore, one would not expect to see positive protein balance in the condition of starvation.

    The nitrogen from amino acid breakdown is 

    • Stored in the liver

    • Converted to urea

    • Converted to fat.

    • Oxidised to carbohydrate.

    Correct Answer
    A. Converted to urea
    Explanation
    When amino acids are broken down in the body, the nitrogen component needs to be eliminated as it can be toxic. The liver plays a crucial role in this process by converting the nitrogen into urea, a less toxic compound. Urea is then transported to the kidneys and excreted in urine. This conversion allows the body to safely eliminate the nitrogen waste while retaining the carbon and other components of the amino acids for energy production or storage. Therefore, the correct answer is that the nitrogen from amino acid breakdown is converted to urea.

    Cooking an egg alters its appearance due to 

    • Denaturation

    • Esterification.

    • Detoxification.

    • Emulsification.

    Correct Answer
    A. Denaturation
    Explanation
    Cooking an egg alters its appearance due to denaturation. Denaturation is a process in which the proteins in the egg are unfolded and their structure is changed by heat. This causes the proteins to coagulate and form a solid mass, resulting in the cooked appearance of the egg. Esterification is a process in which esters are formed, detoxification refers to the removal of toxins, and emulsification is the process of mixing two immiscible substances. None of these processes are responsible for the change in appearance when cooking an egg.

    As one finds his or her weight loss slowing during a weight control program, the best practice is to 

    • Increase physical activity.

    • Go off the weight control program and take a break.

    • Restrict more food choices.

    • Reduce food intake to 1,000 kcalories.

    Correct Answer
    A. Increase physical activity.
    Explanation
    As one finds his or her weight loss slowing during a weight control program, increasing physical activity is the best practice. This is because physical activity helps to burn calories and increase metabolism, which can aid in weight loss. By increasing physical activity, one can create a calorie deficit and continue to lose weight. Going off the weight control program and taking a break may lead to weight gain. Restricting more food choices or reducing food intake to 1,000 kcalories may not be sustainable or healthy approaches to weight loss.

    Acquiring sufficient vitamin B12 from the diet may be a problem to vegans because 

    • Phytic acid in vegetable proteins may inhibit its absorption.

    • It is only found in animal products.

    • They lack the R-protein in the stomach.

    • Deficiency may result from high intakes of legumes.

    Correct Answer
    A. It is only found in animal products.
    Explanation
    Vitamin B12 is primarily found in animal products such as meat, fish, eggs, and dairy. It is not naturally present in plant-based foods, which makes it difficult for vegans to acquire sufficient amounts of this vitamin solely from their diet. Therefore, the statement "it is only found in animal products" is a valid explanation for why acquiring sufficient vitamin B12 may be a problem for vegans.

    • Have obvious symptoms

    • Binge eating

    • Tend to be very thin

    A disorder in which frequent bingeing and possibly purging occurs is called 

    • Compulsive overeating.

    • Anorexia nervosa.

    • Hypoglycemia

    • Bulimia

    Correct Answer
    A. Bulimia
    Explanation
    Bulimia is a disorder characterized by frequent episodes of binge eating followed by purging, which can include self-induced vomiting, excessive exercise, or the use of laxatives. This behavior is typically driven by a fear of gaining weight and a distorted body image. Compulsive overeating refers to a different disorder where individuals frequently consume large amounts of food but do not engage in purging behaviors. Anorexia nervosa is an eating disorder characterized by an intense fear of gaining weight and a distorted body image, leading to severe restriction of food intake. Hypoglycemia is a medical condition characterized by low blood sugar levels and is not directly related to bingeing or purging behaviors.

    • Sugar and fat in food.

    • Nutrients in food

    • Fat in food

    • Designed to be adequate for almost all healthy people.

    Correct Answer
    A. Designed to be adequate for almost all healthy people.
    Explanation
    The RDA (Recommended Dietary Allowance) for nutrients is designed to provide adequate amounts of nutrients for almost all healthy individuals. It takes into consideration the needs of the majority of the population and aims to prevent nutrient deficiencies. The RDA is not set at more than twice the requirements or the minimum amounts for the average adult male, nor is it designed to prevent deficiency disease in only half the population.

    • Kwashiorkor

    • Pellagra

    • Scurvy

    • Beriberi

    Correct Answer
    A. Beriberi
    Explanation
    Beriberi is a disease caused by a deficiency of thiamin, also known as vitamin B1. Thiamin is essential for the proper functioning of the nervous system and the metabolism of carbohydrates. Symptoms of beriberi include weakness, fatigue, nerve damage, muscle wasting, and cardiovascular problems. It is commonly found in populations that rely heavily on polished rice as their main source of food, as the process of polishing removes the thiamin-rich outer layer of the grain.

    If you wanted to add significant quantities of vitamins and minerals to your diet from the food you eat, a good choice would be 

    • A doughnut made with enriched white flour.

    • A fortified breakfast cereal such as Total Raisin Bran.

    • A banana.

    • Apple juice.

    Correct Answer
    A. A fortified breakfast cereal such as Total Raisin Bran.
    Explanation
    A fortified breakfast cereal such as Total Raisin Bran is a good choice for adding significant quantities of vitamins and minerals to your diet. Fortified cereals are specifically enriched with essential nutrients that may be lacking in the average diet. They often contain added vitamins, such as vitamin D, vitamin B12, and folic acid, as well as minerals like iron and calcium. This makes them a convenient and efficient way to increase your intake of these important nutrients. In comparison, a doughnut made with enriched white flour, a banana, or apple juice may not provide the same level of fortified nutrients.
