Ans: Diabetic ketoacidosis: Ketoacidosis is a serious complication of diabetes that occurs when the body produces high levels of blood acids called ketones.

This results in increased formation of ketones. When the ketones produced are more than what the body can handle, they accumulate in the blood, resulting in ketoacidosis.

20. Classify different methods of cooking. Explain any 3 methods in detail.

Ans: The different types of cooking are,

Boiling: Foods are cooked by placing them in boiling water at 100°C and maintaining this temperature till the desired stage of cooking has been reached.
Toasting: Generally applied to bread slices, which are browned on both sides by keeping them between two grilles.
Poaching: This method is generally used for eggs. This involves cooking in the minimum amount of liquid at a temperature of 80-85°C. Fish and fruits are also poached.
Baking: A dry method of cooking, it combines steam, which is generated while food is cooked.
Blanching: Blanching is a cooking process wherein a food, usually a vegetable or fruit, is scalded in boiling water or oil, removed after a brief, timed interval, and finally plunged into iced water or placed under cold running water (shocking or refreshing) to halt the cooking process.
Steaming: This method uses steam as the medium of cooking. The food is surrounded by steam and is cooked by the heat supplied from the steam.
Pressure cooking: In this method, the food is cooked under pressure, and with an increase in pressure, the temperature also correspondingly increases. Thus, the food is cooked very fast.

21. Discuss the physiological mechanisms that regulate blood glucose in the body. How are these disturbed in diabetes?

Ans: In a normal healthy person, the pancreas releases insulin to help the body store and use the sugar from the food they eat. In diabetic individuals, the pancreas (the organ that produces insulin) cannot produce enough insulin, or whatever is produced is not efficiently used by the body, and sugar builds up in the blood (hyperglycemia). It results from a defect in insulin secretion, insulin action or both.

Another concept, important to diabetes status, which needs special mention here, is Glycosylated Haemoglobin (HbA1c). When the concentration of glucose in blood rises, more of it gets attached to haemoglobin (which is a pigment present in red blood cells that carries oxygen to the cells of the body), forming glycosylated haemoglobin (HbA1c). In a normal individual without diabetes, the HbA1c concentration varies from 5-6%, while in diabetics, it increases to over 6% of the total haemoglobin, depending on the blood glucose level. HbA1c shows the general trend of glucose levels in the blood during the previous 2-3 months. HbA1c helps determine how well a person’s diabetes is being controlled over time.

22. What are eating disorders? Explain any two types of eating disorders. Also, enumerate the ways to manage these eating disorders.

Ans: Eating disorders are illnesses in which people experience severe disturbances in their eating patterns/behaviours, and related thoughts and emotions.

Anorexia Nervosa :

An intense fear of weight gain or becoming fat despite the individual’s underweight status.
Profound weight loss
Dieting and avoiding meals

Bulimia Nervosa :

Purging (self-induced vomiting) after meals.
Frequent fluctuations in weight.
Eating a large amount of food in a short time.

Malnutrition due to low or poor consumption of energy-giving macronutrients, such as carbohydrates, fats, proteins and/or micronutrients relative to individual needs is a concern with both anorexia nervosa and bulimia nervosa. In both cases, consideration needs to be given to symptoms of the starvation syndrome. Starvation syndrome here refers to starvation caused either by food restriction/dieting, as in anorexia nervosa, or problems related to food absorption, as in purging or excessive exercise may mean that insufficient energy is consumed for weight maintenance in bulimia nervosa.

23. Explain the role of dietary factors in the cause of hypertension. What dietary changes are beneficial to control it?

Ans: Unhealthy diets consisting of high fat, salt, sugar (HFSS) include chips, fried foods, sugar-sweetened carbonated and non-carbonated beverages, pizzas, burgers, ready-to-eat noodles, potato fries, and confectionery items.

Excessive salt intake has been associated with increased prevalence of hypertension and a rise in systolic pressure with age.
Excessive sodium intake can cause the body to retain fluid and also cause arteries/blood vessels to constrict, which increases blood pressure.
Also a diet high in calories, saturated fats like ghee, butter and food rich in animal fats (such as whole milk, red meat, organ meats), trans fats (deep fried snacks/foods, bakery products, etc.) and processed, packaged foods such as chips, cookie,s etc.
Packaged and processed foods often have sodium added during manufacturing, either as salt or as baking soda.

The main objective of dietary management of hypertension is to:

Achieve gradual weight loss in overweight and obese individuals and maintain weight slightly below the normal level,
Reduce sodium intake and maintain fluid and electrolyte balance.
Maintain adequate nutrition
Slow down the onset of complications

24. What are food hazards? Explain different types of food hazards with their example.

Ans: A food hazard refers to any agent with the potential to cause adverse health consequences for consumers. It occurs when food is exposed to hazardous agents, which result in contamination of that food.

Food hazards may be biological, chemical and physical.

Biological hazards: They include microorganisms such as bacteria, viruses, yeasts, moulds and parasites. Some of these are pathogens or may produce toxins. A pathogenic microorganism causes disease and can vary in the degree of severity. Examples of biological hazards include Salmonella, E. coli and Clostridium botulinum.
Chemical hazards: The chemical hazards vary in the aspect of production they are related to. Some potential chemical hazards could occur before a processor receives product, such as the improper use of pesticides or antimicrobial residues. Others could be chemicals used on processing equipment, such as oils used on equipment or sanitisers.
Physical hazards: They include objects that are hard or sharp, such as glass, metal, plastic, stones, pits, wood, or even bone. Physical hazards can lead to injuries such as choking, cuts, or broken teeth. Some foreign material in food products may not be a physical hazard but rather an undesirable foreign material, such as hair, insects, or sand, that is not likely to cause injuries.
