Report on Macronutrients: NUTR2001 Assessment 2 Part A

This report, prepared for NUTR2001 (Human Nutrition 1) Assessment 2 Part A, identifies and discusses the roles of macronutrients, including proteins, carbohydrates, and lipids, in human health. It explains that proteins, composed of amino acids, are essential for tissue repair and building, carbohydrates provide the primary energy source, and lipids are involved in hormone and steroid production. The report highlights the importance of a balanced diet for maintaining health and mentions the focus on factors contributing to macronutrient excess or deficiency, and related illnesses that will be further discussed in Part B. It references key articles on macronutrients and their impact on appetite and energy intake. The report aims to provide a foundational understanding of macronutrients and their significance in human metabolism, adhering to the assessment's learning outcomes.

Nutrients are essential because they provide energy, promote growth and development,
and regulate the body processes. A proper diet can be one of the most effective ways of
maintaining natural health. The purpose of this report is to identify the macronutrients and the
role that they play in health.
There are different types of macronutrients. They include proteins, carbohydrates, and
lipids. Proteins consist of amino acids and make up most of the cell structure, including the cell
membrane. Their primary biological function is to repair, and build worn out tissues. Proteins
from animal sources contain all the essential amino acids needed, unlike plant sources of protein.
Carbohydrates are the body’s primary source of energy. It is stored in the liver as Glycogen.
They are essential for fat oxidation. The primary dietary source of carbohydrates is rice, corn,
and wheat-based products (Ai & Jane, 2016). Lipids are used in making steroids and hormones.
It is stored in adipose tissue. Although fats have received a bad reputation some are essential for
health and wellbeing. Part B will highlight more about the macronutrients, their biological
functions and the main sources of the macronutrients (Carreiro et al., 2016)
Macronutrients are needed in the body for the general health of the body. None is more
important than the other since they all have different functions to carry out (Campbell, 2017). In
part B the various factors that contribute to excess nutrients or a deficiency of macronutrients in
the body will be highlighted. An increase or a decrease in a specific type of nutrient can result in
various illnesses. It is, therefore, important to adhere to the recommended dietary intake; this will

be discussed further in Part B. In addition, the various food related illnesses will be discussed in
detail in part B. The two major articles that will be focused on in Part B are:
