Question
Which of the following substances is NOT correctly matched with its caloric value? carbohydrate - 4 calories/gram fat - 4 calories/gram water - 0 calories/gram protein - 4 calories/gram fiber - 0 calories/gram "Essential" nutrients describe nutrients that the body is not able to produce. the body is able to produce so no food source is needed. are needed in very low quantities. cannot be found within food sources. make up a Urge proportion of the body. Which molecules are required by the body, but do not provide energy? Carbohydrates Proteins Fats Vitamins All of the above The four stages of food processing are, in order: ingestion, absorption, elimination, digestion, ingestion, elimination, digestion, absorption ingestion, digestion, absorption, elimination, digestion, absorption, ingestion, elimination, elimination, absorption, digestion, ingestion. On food labels, "fibers" refers to plant material that we can't fully digest, but is important for maintaining a healthy digestive tract, "fiber" refers to a type of carbohydrate. nucleic acid. lipid. amino acid, protein. Which of the following is not associated with obesity? Type 1 diabetes Type; diabetes hypertension (high blood pressure) increased risk of stroke increased risk of heart attack Why isn't a BMI (Body Mass Index) a perfectly reliable way to estimate your health? It considers your height but not your weight. It considers your weight but not your height. It doesn't take into account body composition such as muscle mass. Your relative amount of body fat is not correlated with the risk of illness and death. It only takes into account your resting energetic needs. When a person absorbs more glucose from their diet than they need, the excess is flushed from the system as waste. is stored as simple sugars in the muscle and liver cells. is stored as complex sugars in the fat cells. is it stored as ATP in the muscle cells. is stored as glycogen in the muscle and liver cells, and stored as fat in the adipose (fat) cells.Explanation / Answer
1. b) fat is wrongly matched with its caloric value because fat gives 9 calories per gram. Others are in correct proportion.
2. Correct: a) Essential nutrients cannot be synthesized by body.
False: b) Body is able to produce so no food source is needed.
No. Essential nutrients can't be synthesized by body so they have to be acquired as dietary supplement.
c) Essential nutrients are needed in low qualities.
No. Essential nutrients are divided into two categories. Micro nutrients and macro nutrients based on the amount required by the body.
Micro nutrients are required in less quantities ( typically few milligrams a day)
Macro nutrients are required in large quantities ( few grams a day)
d) Essential nutrients can't be found in food sources.
No. On the contrary, they are obtained only through food sources.
e) Make up a large proportion of body.
No. They are required on a daily basis and average requirement of each nutrient varies greatly. Also, excess amount of certain nutrients are even toxic to the body.
3) Carbohydrates, Proteins and fat are all required by the body and they tend to provide energy.
Vitamins on the other hand, they are inorganic chemical compounds which are also required by the body but they won't provide energy. Instead, they convert food into energy, boost immune response, act as precursors to certain reactions and function as antioxidants etc.,
4) Four stages of food processing:
5) a) Carbohydrate
Fiber is made up of complex carbohydrate molecules and is mainly composed of non-starch polysaccharides such as cellulose, lignin, pectin, xylose, raffinose etc.,. Human gut doesn't have enzymes to break down fiber and it can't be hydrolyzed in small intestine. Hence, it passes through the body undigested.
6) Answer: a) Type 1 diabetes
Because type 1 diabetes is a auto immune disorder in which the body immune cells attack insulin producing cells causing lack of insulin production. This is a genetic disorder and usually develops in children and teenagers.
False: b) Type II diabetes also called as insulin resistant diabetes is caused by improper utilization of insulin to absorb glucose into cells. This results in increase of glucose in bloodstream. Obesity causes stress in ER machinery of cells which in turn suppresses the signals of insulin receptors causing type I diabetes.
c)d)e) Hypertension, Risk of stroke and Risk of Heart attack are all caused by same reason.
Obesity can cause blocking of arteries by plaque formation due to high amount of fat presence. This can cause obstruction of blood flow causing hypertension or risk of heart attack. If this gets more severe, the arteries will rupture causing a blood clot near brain leading to stroke.
7. C) BMI doesn't take into account body composition such as body mass.
BMI is only calculated based on height and weight proportions of a body. It doesn't take into account body composition such as body mass, bone density, overall body composition, sex etc., It doesn't give actual body fat composition or indicate obese condition of an individual. So, it is not an accurate way of estimating health.
8. When a person absorbs excess amount of glucose from their diet, then it will be stored as glycogen in the muscle and liver cells and as fat in adipose tissues. Because, the presence of sugar, fatty acids or proteins in the intestine stimulates pancreas to secrete insulin hormone. This hormone directs the cells to build glycogen from excess glucose, fat from fatty acids and proteins from amino acids. However, cells can also convert and store fat from glucose and amino acids incase of extra glucose but it is less efficient and requires more energy for conversion.
