Calorie:
A calorie is a unit of measurement used to quantify the amount of energy in food. It represents the energy required to raise the temperature of one gram of water by one degree Celsius. In the context of nutrition, calories refer to the energy that our body needs to function properly and perform daily activities.
To determine the meaning of a calorie, you can look it up in a dictionary or search online. Websites like Merriam-Webster or Oxford English Dictionary will provide you with a precise definition. You can also consult a nutrition textbook or scientific resources to gain a deeper understanding.
Undernutrition:
Undernutrition is a state of inadequate nutrition, where the body does not receive enough nutrients to function optimally. It occurs when a person consumes fewer calories or essential nutrients than their body requires for growth, maintenance, and repair.
To better understand undernutrition, you can start by examining its components: calorie deficiency and nutrient deficiency. A calorie deficiency refers to not consuming enough calories, while a nutrient deficiency refers to a lack of specific nutrients such as proteins, vitamins, or minerals.
To further your understanding, you can explore reputable sources like academic journals, books, or international health organizations like the World Health Organization (WHO) or the United Nations (UN) websites. These sources provide extensive information on the causes, consequences, and potential solutions to undernutrition. Additionally, consulting a nutritionist or dietitian can provide valuable insights on the topic.
