Learning Outcomes
i. Identify common nutritional problems related to protein and energy.
ii. Understand the consequences of protein-energy malnutrition.
iii. Recognize the signs and symptoms of protein-energy malnutrition.
Description of Learning Outcomes
Students will grasp the concept of nutritional issues, particularly those concerning protein and energy, by the end of this lesson. They will be aware of the health problems caused by insufficient protein and energy intake and will be able to identify the telltale signs of malnutrition in these areas.
Summary of Lesson
This lesson focuses on the crucial role of protein and energy in our diet and what happens when we don't get enough of them. Protein-energy malnutrition is a serious concern in many parts of the world and can lead to significant health issues, especially in children.
Proteins and calories are like the fuel and building blocks for our body. Proteins help build muscle, repair tissue, and create enzymes and hormones. Calories provide the energy needed for our body to function. But what if we don't get enough? This situation can lead to problems like stunted growth in children, weakened immune systems, and general fatigue.
In more severe cases, lack of protein can lead to conditions like Kwashiorkor and Marasmus. Kwashiorkor often results in swelling, an enlarged liver, and skin and hair changes, while Marasmus leads to severe weight loss and muscle wasting. Both are forms of protein-energy malnutrition and are serious health conditions that need immediate attention.
List of Important Questions for Self-Study
i. What is protein-energy malnutrition?
ii. How can insufficient protein affect the body?
iii. What are the signs of Kwashiorkor and Marasmus?
iv. Why is calorie intake important for the body's energy needs?
Important Terminologies Used in Lesson
i. Protein-Energy Malnutrition (PEM): A range of pathological conditions arising from coincident lack of dietary protein and/or energy in varying proportions.
ii. Kwashiorkor: A form of severe protein malnutrition characterized by edema and an enlarged liver.
iii. Marasmus: Severe undernourishment causing a child's weight to be significantly low for their age.
iv. Calories: Units of energy that measure the amount of energy in food and drinks.
v. Nutritional Deficiency: The result of the body not getting enough of the nutrients it needs.
vi. Metabolism: The chemical processes that occur within a living organism to maintain life.
