Explanation / Answer

Question 2 : recurrent episodes of extreme overeating followed by self-induced vomiting

The disorder where extreme over eating is followed by self induced vomiting is known as Bulimia nervosa. Binge eating is followed by inappropriate purging measure or compensatory behaviour such as excessive workouts, use of laxative or diuretic drugs, fasting or vomiting to avoid weight gain. There is loss of control over eating.

Question 3 : coexistence of underweight and obesity in the same region (most common in developing countries)

It is a nutritional paradox where excessive rates of obesity are observed in children from non-obese parents. The factors which have favoured this kind of trend are easy availability and preference for cheap, energy dense and calorie rich foods (especially from fast food restaurants) and sedentary lifestyle by children. There is need for better education about nutrition and health, buying of healthy foods and spending good amount of time for some physical activity.

Question 4 : increased consumption of sugar

Increased consumption of sugar represents a nutrition transition. Not just sugar, but consumption of foods high in saturated fat and bad cholesterol, refined foods and lower consumption of foods with polyunsaturated fatty acids and fibre has led to transition.

Question 5 : Obesity control

GOBI refers to Growth Monitoring, Oral Re-hydration, Breastfeeding and Immunization.

Question 6 : Biotechnology

Biotechnology is helping to create new seed varieties which are higher in nutrition, physical attributes and disease resistant.

Question 7 : unequal distribution of food is the major cause of undernutrition.

Question 8 : CDC

Based on the estimates for two major categories of food borne illnesses ( identified and unidentified pathogenic agents, CDC provides annual summary of foodborne outbreaks by etiology and food category.

Question 9 : Alkaline

Clostridium botulinum is a gram positive bacteria, heat resistant and flourishes in alkaline environment.

Question 10 : Clostridium botulinum

This bacteria grows on food and produces a toxin that causes paralysis. The disease is known as botulism.

Question 11 : Hypertension

Female athlete triad is the condition characterized by disordered eating, lack or dysfunctional menstrual cycle and osteoporosis.

Question 12 : Bulimia Nervosa

Question 13 : Anorexia Nervosa

Question 14 : 60

Study conducted by this institute found that 66% of adults having BMI in healthy range did greater than or equal to 60 min of physical activity of moderate intensity per day.

Question 15 : enhances the action of insulin

Question 16 : improving fitness by placing extra physical demand on the body.

It’s a sports training fitness regime where athletes work harder to continually improve their fitness as their bodies get used to the regular workouts.

Question 17 : FIT stands for frequency, intensity and time.

Frequency is the how often the physical activity is done, intensity is the level of physical activity (easy, medium or hard) and time is the duration for which each session is undertaken.

Question 18 : 3-5 days per week.

Ideally 20-60 minutes per exercise per day is recommended. The higher the intensity of exercise, lesser time is required to obtain the desired fitness.

Question 19 : 50-80% of heart rate

Question 20 : Sprinting in the 100 meter race

Sprinting is an anaerobic event where high intense muscle power is required within seconds. The others – biking up a mountain, running 10 km race and playing in a football game requires sustained energy release which can be obtained from ATP.

Question 21 : Aerobic metabolism acts more quickly

Question 22 : an unwanted effect of an overly vigorous warm up is glycogen depletion.

Question 23 : fuel sources providing energy during power walks is fatty acids and glucose.

Question 24 : the main disadvantage of using fat as fuel is the limitation of anerobic metabolism.

Fat is present in unlimited supply as well as it provides 9kcal of energy.

Question 25 : Joseph’s performance has been impaired.

Question 26 : 1500 – 1625 kilocalories

Question 27 : Right after exercising

The athlete must consume carbohydrates a few hours after training so that ample amount of glycogen gets stored in the body.

Question 28 : cross country skiing

Carbohydrate loading is used by athletes to maximize the glycogen storage in muscles and liver.

Question 29 : inadequate dietary intake

Question 30 : heat stroke

Heat stroke is caused by prolonged exertion in high temperatures. The body gets overheated to temperature nearing 104 F

Question 31 : male distance swimmer

Question 32 : the loss of menstrual cycle

Question 33 : increase the use of fatty acids as a fuel source.

Question 34 : creatine

It is the most rapid form of energy used on the onset of exercise and also gives energy during high intensity exercise.

Question 35 : False

Question 36 : True

Regular physical activity increases high density cholesterol and helps in maintaining healthy blood pressure.

Question 37 : True

Question 38 : True

Question 39 : True

Question 40 : False

Question 41 : True

Question 42 : False

Refrigerating does not kill the bacteria it only slows down their growth.

Question 43 : True

Question 44 : False

Urine colour is better indicator of dehydration. Darker the urine, more is dehydration.
