Question 1

Briefly discuss the main determinants of nutrient requirements. Briefly explain the concept of Recommended Dietary Allowances (RDA) and Estimated Average Requirement (EAR) What is the purpose behind setting the dietary guidelines?

Accepted Answer

Nutrient requirements are highly variable, determined by an individual's unique physiological state, lifestyle, and health status. Understanding these determinants is crucial for tailoring dietary advice. Dietary reference values like Estimated Average Requirement (EAR) and Recommended Dietary Allowance (RDA) provide scientific benchmarks for nutrient intake. Furthermore, national dietary guidelines translate this scientific knowledge into practical, food-based recommendations to promote overall

Question 2

What do you understand by Chemical score and biological value of protein? How are these used to know the quality of protein in the diet? Explain the mechanism of regulation of blood glucose concentration. List some important functions of carbohydrates.

Accepted Answer

Understanding the quality of dietary protein involves various assessment methods, with Chemical Score and Biological Value being prominent examples. These methods help in evaluating how effectively the body can utilize proteins from different food sources. Furthermore, the body meticulously regulates blood glucose levels through a hormonal feedback system to maintain metabolic homeostasis. Carbohydrates play a multifaceted role in the body, serving as the primary energy source and contributing t

Question 3

Briefly discuss the digestion, absorption and transportation of carbohydrates, proteins and fats. Enumerate the potential health benefits of dietary fiber. Why is LDL referred to as bad cholesterol and HDL as good cholesterol?

Accepted Answer

The human body efficiently breaks down, absorbs, and transports macronutrients—carbohydrates, proteins, and fats—to derive energy and building blocks. This complex process involves enzymatic hydrolysis, specialized transport mechanisms across the intestinal lining, and systemic circulation via blood and lymphatic systems. Additionally, dietary fiber, though not digested, plays a crucial role in maintaining health. The differentiation between LDL and HDL cholesterol highlights the varying impacts

Question 4

Diagrammatically explain the functions of two major fluid compartments of the body. Differentiate between Glycemic Load (GL) and Glycemic Index (GI), giving examples. Explain the following:

Question 5

Explain the term calcium homeostasis. How tryptophan is converted to niacin? Explain with the help of flow chart. Briefly describe the role of vitamin E and selenium in lipid peroxidation.

Accepted Answer

The human body meticulously regulates various physiological processes to maintain optimal health. Among these, calcium homeostasis and the metabolism of essential nutrients like tryptophan are fundamental. Additionally, endogenous defense mechanisms, such as those involving vitamin E and selenium, are critical in protecting against cellular damage like lipid peroxidation.

This comprehensive response will delve into the intricate mechanisms governing calcium balance, trace the biochemical pathwa

Question 7

List the different components of energy expenditure. Define BMR and briefly discuss the factors which influence BMR Write the functions of following:

Accepted Answer

Energy expenditure is crucial for understanding nutrient requirements and maintaining energy balance. It is primarily divided into three main components: Basal Metabolic Rate (BMR), the Thermic Effect of Food (TEF), and the energy expended through Physical Activity (PA).

Basal Metabolic Rate (BMR) represents the largest portion of daily energy expenditure. It is defined as the minimum amount of energy required to sustain vital bodily functions in a completely resting, post-absorptive state, and

Question 8

Briefly discuss the following: i)Nutrient needs and dietary management for lactating women ii)Dietary modification for the elderly What do you understand by the term calamity and emergency? Briefly discuss the measures to avoid protein energy malnutrition and micronutrient deficiency during emergenc

Accepted Answer

Understanding specific nutritional needs and managing dietary intake across different life stages and emergency situations is crucial for promoting health and preventing malnutrition. Lactating women require significantly higher energy and nutrient intake to support milk production, while the elderly need dietary adjustments to address physiological changes and potential health issues. Furthermore, calamities and emergencies present unique challenges to food security, necessitating targeted nutr
