Nutrition is a scientific discipline that concentrates on healthy eating with great attention to a balanced diet. The food people consume their health status. Therefore, consuming nutritious meals supports healthy life, while unhealthy food choices increase health risks.
According to our professional tutors, nutrition is a process of consuming, absorbing, and using nutrients required by the body to grow, develop, and maintain life. Appropriate nutrition should not be in low or excess amounts but rather in adequate proportion characterized by various nutrients. Access to a healthy diet results in easy maintenance of a desirable weight and composition with improved physical and mental wellness. Healthcare professionals always advise people to embrace good nutrition for various reasons, including reducing the risk of disability and diseases.
Types of macronutrients required by the body for proper functioning
Based on Essay For All professionals, macronutrients are the nutrients the body or people require in large amounts. The main classifications of macronutrients are carbohydrates, proteins, and fats.
Proteins are an integral component of a balanced diet comprising amino acids. Amino acids can be essential and non-essential. Essential amino acids are the ones that must be supplied through food, while the non-essential amino acids are the ones that the body can make. People can get protein from plant-based or animal-based sources based on availability, affordability, and convenience.

Lack of adequate protein may result in deficiency diseases like kwashiorkor, especially among children. Children in developing countries are highly vulnerable to kwashiorkor s deficiency disease resulting from inadequate intake of proteins. With limited access to protein foods, healthcare practitioners should use protein supplements to help children avoid protein deficiency risks.
The body requires the supply of fats in adequate amounts. There are wide-ranging sources of fats, some of which are dairy foods and meat products. However, our nutrition nursing assignment help professionals highly prohibit the excess consumption of fats. Unregulated intake of fats has contributed to increasing cases of obesity and overweight. However, fats in the body are essential for;
- Supporting brain health
- Minimize inflammation
- Support absorption of fat-soluble vitamins
- Help organs in hormone production
- Joint lubrication
It is healthy for people to engage in physical activity to minimize their risk of developing liver disease, high cholesterol, and obesity. Avoiding saturated and poly-saturated fats also supports healthy amounts of fat intake.
The common types of carbohydrates are fiber, starch, and sugar. Sugars are the simplest form of carbohydrates, readily broken down by the body and absorbed to provide instant energy. Excess sugar consumption is unhealthy since it is likely to trigger high blood sugar levels, making one vulnerable to type 2 diabetes and its related complications.
Fiber is a complex form of carbohydrate that also plays a crucial role in the body. It helps in improving the process of digestion and also in energy production. Adequate fiber intake in diets minimizes people’s risk of developing chronic diseases like colorectal cancer, cardiovascular diseases, and diabetes.
These are types of nutrients needed by the body in small amounts. The main types of micronutrients required in the body are minerals and vitamins. They all play a significant part in the proper and optimal functioning of the body. According to our nutrition nursing assignment help experts, micronutrients help in supporting healthy development, prevention of diseases, and also the overall well-being of a person.
All vitamins are essential and must be supplied by the food except for vitamin D, which the body makes. Micronutrients also help in the production of hormones, and enzymes, among other chemical substances for optimal body growth and development. Micronutrients that help in boosting the immune system include vitamin B6, vitamin C, E, magnesium, and zinc.
Some individuals need an adequate intake of essential micronutrients because of inadequate knowledge of food sources. However, there are increased nutrition awareness programs and education to help sensitize people on how to get all the desired nutrients beneficial to their bodies.
The undernutrition concept
Undernutrition is a form of malnutrition characterized by the inability to get enough nutrients, resulting in severe health conditions. If a person fails to get adequate amounts of food or access enough nutritious diets or even suffers from a medical condition affecting their ability to absorb nutrients, they will likely suffer undernutrition. The two main under-nutrition types are energy under-nutrition and micronutrient under-nutrition.
Energy under-nutrition is, also known as protein-energy malnutrition, very popular in underdeveloped countries. Protein-energy malnutrition (PEM) is a condition that affects both children and pregnant women. Pregnant women have increased chances of bearing underweight children. Among school-going children, PEM impairs their academic performance of children due to their inability to concentrate in class. Some commonly addressed forms of protein-energy malnutrition by nutritionists, and related nurses are; kwashiorkor and marasmus.
Kwashiorkor is a protein deficiency caused by a lack of protein. The availability of fat or carbohydrate in the diet cannot stop a child from getting kwashiorkor. Bloated abdomens, thin legs, and arms characterize the condition. In this case, parents, especially mothers, should ensure an adequate supply of proteins in the diet they offer children to support their overall growth and development.
Marasmus results from starvation. It is a form of severe undernutrition whereby a child suffers a total lack of energy, suffering impaired growth, infertility, wasting, and even death. Due to extreme starvation, the body breaks down all energy reserves and even its tissues for survival. The outcome on the body is always emaciation. Poverty, natural disasters, and limited access to the desired diet are among the leading causes of marasmus.
Common signs of undernutrition
With a limited supply of body nutrients over time, a person is likely to suffer various signs and symptoms such as;
- Hair thinning
- Mood disruptions
- Poor wound healing
- Dry skin
- Intolerance to cold
- Reduced concentrations
- Frequent illness
- Lowered appetite
Based on Essay For All tutors, overnutrition is the excess consumption of certain nutrients such as fats, calories, or proteins. The expected outcome of overnutrition is obesity or overweight. Overnutrition from macronutrients is very common. However, excess consumption of micronutrients rarely causes overnutrition. However, a high accumulation of micronutrients in the body becomes toxic to the body, which is why it quickly causes acute poisoning. Overnutrition predisposes people to the risk of developing severe diet-associated chronic disorders like;
- Cardiovascular disease
- Type 2 diabetes
Based on Essay For All nutrition nursing assignment doers, excess intake of calories results in wide-ranging health conditions such as;
- High cholesterol
- High blood pressure
- Weight gain
Symptoms of nutrients always vary depending on the condition that a patient suffers. However, the common symptoms entail;
- Cracked and dry lips
- Eye irritation
- Light sensitivity
- Heartbeat irregularities
- Increased urination frequency
- Cloudy urine
Whenever you realize a person is presenting such symptoms, advising them to seek further guidance and assistance from a healthcare provider is very important.
People at high risk of under-nutrition
People of advanced age always suffer various nutrition challenges, especially the risk of undernutrition. The nutrition of the elderly deteriorates because of reduced appetite, institutionalization, reduced mobility, and decreased absorption of nutrients.
People suffering from chronic illnesses tend to suffer from inconsistent appetite. Cancer is among the chronic diseases that affect the appetite of individuals, especially after receiving specific cancer treatments. Other chronic disorders also affect the calorie absorption abilities of the body. Whenever people with chronic conditions spend a significant part of their time in hospitals, they are at high risk of undernutrition.
The undernutrition concern is very prevalent among children. While growing up, children have increased nutritional needs to support their growth and development. However, the inability to access and consume adequate macronutrients and micronutrients will likely impair a child’s developmental process.
Parents need sufficient education to supply their children with a balanced diet. If a child shows undernutrition, caregivers or parents should seek medical attention and advice since they can get supplements to help curb the risk of developing deficiency diseases.
Poor and low-income households
Overnutrition is a form of malnutrition that is prevalent among affluent households. For instance, such people have adequate access to different foods and hence consume specific foods in excess. However, people from low and poor-income households face a constant challenge of access to capital vita to avail necessary foods to supply the required nutrients in the body. Even if they get the needed nourishment, their consumption could be better, and they can hardly meet the body’s nutritional requirements.
Possible causes of malnutrition
- Undernutrition results from;
- Conditions that demand long-term intravenous feeding
- Malabsorption disorders like inflammatory bowel disease
- Eating disorders like bulimia and anorexia
- Mental health conditions like dementia and depression
- Additional calorie needs like childhood, breastfeeding, or pregnancy
- Medical conditions resulting in swallowing challenges and nausea
- Limited access to nutritious foods
- Limited financial resources
