Nutrient deficiencies – Although the so-called diseases of civilization—for example, heart disease, stroke, cancer, and diabetes—will be the focus of this article, the most significant nutrition-related disease is chronic undernutrition, which plagues more than 925 million people worldwide,
- Undernutrition is a condition in which there is insufficient food to meet energy needs; its main characteristics include weight loss, failure to thrive, and wasting of body fat and muscle,
- Low birth weight in infants, inadequate growth and development in children, diminished mental function, and increased susceptibility to disease are among the many consequences of chronic persistent hunger, which affects those living in poverty in both industrialized and developing countries.
The largest number of chronically hungry people live in Asia, but the severity of hunger is greatest in sub-Saharan Africa, At the start of the 21st century, approximately 20,000 people, the majority of them children, died each day from undernutrition and related diseases that could have been prevented.
The deaths of many of these children stem from the poor nutritional status of their mothers as well as the lack of opportunity imposed by poverty, Only a small percentage of hunger deaths is caused by starvation due to catastrophic food shortages. During the 1990s, for example, worldwide famine (epidemic failure of the food supply) more often resulted from complex social and political issues and the ravages of war than from natural disasters such as droughts and floods.

Which is the most common of all nutrient deficiency diseases?
4. Folate – Folate, or vitamin B-9, plays an essential role in creating red blood cells and DNA, fetal development, and brain development. Folate deficiency is the most common nutritional deficiency in pregnant women and can lead to severe congenital disabilities and growth issues.
Beans; Lentils; Leafy green vegetables; Poultry and pork; Whole grains; Citrus fruits.
If you’re not sure if your diet contains enough folate, consider taking a supplement or consulting a doctor or dietician.
What are the 4 types of malnutrition?
Undernutrition – There are 4 broad sub-forms of undernutrition: wasting, stunting, underweight, and deficiencies in vitamins and minerals. Undernutrition makes children in particular much more vulnerable to disease and death. Low weight-for-height is known as wasting.
It usually indicates recent and severe weight loss, because a person has not had enough food to eat and/or they have had an infectious disease, such as diarrhoea, which has caused them to lose weight. A young child who is moderately or severely wasted has an increased risk of death, but treatment is possible.
Low height-for-age is known as stunting. It is the result of chronic or recurrent undernutrition, usually associated with poor socioeconomic conditions, poor maternal health and nutrition, frequent illness, and/or inappropriate infant and young child feeding and care in early life.
What is a nutrition deficiency?
Nutritional deficiency occurs when the body is not getting enough nutrients such as vitamins and minerals. There are a number of conditions that are caused by nutritional deficiency such as anemia. The body requires vitamins to stay healthy and function properly.
What are nutrient disorders?
NUTRITIONAL DISORDERS Nutrition disorders are diseases that occur when an individual’s dietary intake doesn’t contain the proper amount of nutrients for healthy functioning, or when an individual cannot correctly absorb nutrients from food. Nutrition disorders are often caused by undernutrition, overnutrition or an incorrect balance of nutrients.
- The most significant nutrition-related disease is chronic undernutrition, which plagues quite 925 million people worldwide.
- Undernutrition may be a condition during which there’s insufficient food to satisfy energy needs; its main characteristics include weight loss, failure to thrive, and wasting of body fat and muscle.
Low birth weight in infants, inadequate growth and development in children, diminished mental function, and increased susceptibility to disease are among the various consequences of chronic persistent hunger, which affects those living in poverty in both industrialized and developing countries.
- Malnutrition is that the impaired function that results from a protracted deficiency—or excess—of total energy or specific nutrients like protein, essential fatty acids, vitamins, or minerals.
- This condition may result from fasting and anorexia nervosa; persistent vomiting (as in bulimia nervosa) or inability to swallow; impaired digestion and intestinal malabsorption; or chronic illnesses that end in loss of appetite (e.g., cancer, AIDS).
Malnutrition also can result from limited food availability, unwise food choices, or overzealous use of dietary supplements. Selected nutrient-deficiency diseases are listed within the table.
some nutrient-deficiency diseases: Xerophthalmia (vitamin A): blindness from chronic eye infections, poor growth, dryness and keratinization of epithelial tissues liver, fortified milk, sweet potatoes, spinach, greens, carrots, cantaloupe, apricots.Rickets (vitamin D):weakened bones, bowed legs, other bone deformities fortified milk, fish oils, sun exposure.Beriberi (thiamin) :nerve degeneration, altered muscle coordination, cardiovascular problems pork, whole and enriched grains, dried beans, sunflower seedspellagra’ (niacin) :Diarrhea, skin inflammation, dementia mushrooms, bran, tuna, chicken, beef, peanuts, whole and enriched grains.Scurvy (vitamin C):Delayed wound healing, internal bleeding, abnormal formation of bones and teeth citrus fruits, strawberries, broccoli.Iron-deficiency anemia (iron) :decreased work output, reduced growth, increased health risk in pregnancy meat, spinach, seafood, broccoli, peas, bran, whole-grain and enriched breads.Goiter (iodine):Enlarged thyroid, poor growth in infancy and childhood, possible retardation, cretinism iodized salt, seafood.
Protein-energy malnutrition: Chronic undernutrition manifests primarily as protein-energy malnutrition (PEM), which is that the commonest sort of malnutrition worldwide. Also referred to as protein-calorie malnutrition, PEM may be a continuum during which people—all too often children—consume insufficient protein, energy, or both.
- At one end of the continuum is kwashiorkor, characterized by a severe protein deficiency, and at the opposite is marasmus, an absolute food deprivation with grossly inadequate amounts of both energy and protein.
- An infant with marasmus is extremely underweight and has lost most or all subcutaneous fat.
If untreated, marasmus may end in death thanks to starvation or coronary failure, Kwashiorkor: is usually seen when a toddler is weaned from highprotein breast milk onto a carbohydrate food source with insufficient protein. Carbohydrates: Long-term carbohydrate inadequacy leads to increased production of organic compounds called ketones (a condition referred to as ketosis), which imparts a particular sweet odour to the breath.
- Essential fatty acids : There is additionally a minimum requirement for fat—not for total fat, but just for the fatty acids linolic acid (a so-called omega-6 fatty acid) and omega-3 fatty acid (an omega-3 fatty acid).
- Deficiencies of those two fatty acids are seen in hospitalized patients fed exclusively with intravenous fluids containing no fat for weeks, patients with medical conditions affecting fat absorption, infants given formulas low in fat, and young children fed nonfat milk or low-fat diets,
Vitamins: Although deficiency diseases are described in laboratory animals and humans bereft of single vitamins, in human experience multiple deficiencies are usually present simultaneously. The eight B-complex vitamins function in coordination in numerous enzyme systems and metabolic pathways; thus, a deficiency of 1 may affect the functioning of others Minerals Etc.
What are the two types of nutritional disorders?
CONCLUSION – Nutritional disorders include a wide spectrum of conditions, including generalized undernutrition, overnutrition leading to obesity, the eating disorders and diseases where nutrition has a role in the aetiology. Globally, both undernutrition and obesity are important public health problems.
The treatment of undernutrition is often complicated by factors such as war, famine and infectious diseases. Obesity remains difficult to treat once present, although the advances in the understanding of the physiology of feeding discussed in this chapter are leading to new pharmacological and surgical interventions.
Nutritional interventions in the treatment of diseases may involve the use of therapeutic diets, the administration of dietary supplements or the provision of nutritional support, either enteral or parenteral. Nutritional support is best delivered by a multidisciplinary team.
What happens if you dont eat healthy?
What happens if you don’t eat a healthy balanced diet? What are the risks? We all know that eating healthy is one of the best things we can do for ourselves and our bodies. But do we all really know the risks we are taking if we don’t eat a balanced nutritious diet? Probably not, seeing as though the list of potential risks and dangers could go on forever.
- Eating a diet that is high in junk food is quite unnecessary; in fact, the dictionary meaning of junk food portrays it as something useless and not needed.
- This type of diet will not provide your body with the right amount of nutrients, nor will it benefit energy levels, risk of diseases or weight control.
In fact, as well as not doing any of these things it will also cause a wide range of consequences. We have listed some of these below. Nutrient Deficiencies If you consume foods that don’t provide enough nutrient value, your nutrient levels will start to decline.
There are many, many dangers of a nutrient deficiency, including digestion problems, defected bone growth, anaemia and skin problems. Children are at a high risk of nutrient deficiencies so it is important to make sure that they are being completely nourished with the right foods. Diabetes Because junk food is high in refined carbohydrates, it causes rapid spikes in blood sugar.
This causes an influx of insulin to be released into the blood stream. When this starts to happen often, it can causes a lot of stress on one’s metabolism, which then affects the body’s ability to manage insulin levels. If this continues to happen over a period of time, a person can easily get type 2 diabetes.
When diabetes is not managed well with a healthy balanced diet, the consequences are not nice to say the least! Kidney failure, blindness and lower limb amputation are just a few of those. Weight Gain It is no secret that an unhealthy diet causes weight gain. By unhealthy diet we mean a diet high in processed foods and low in fruit, vegetables, whole grains, beans, legumes, pulses and good fats.
Poor Concentration & Behavioural Problems in Children It’s amazing how much food can really affect us. In both adolescents and children, consuming an unhealthy diet has been linked to poor concentration, social problems and hyperactivity. There is quite a lot of research out there to support this, but a book by Schauss, A.
1980) uses case histories and literature to present a solid argument on just how detrimental an unhealthy diet can be for children’s behaviour. Food allergies, food additives, nutrient deficiencies, intake of junk food and physical inactivity are all highlighted as potential contributors to criminal behaviour.
In addition, an unhealthy diet has also been linked to mental health problems, such as depression, in children and adolescents (O’Neil, A et. al). Starting to consume a healthy balanced diet has even been proven to benefit children with mental health problems.

What are 4 risk factors for nutritional problems?
Abstract – Purpose: This study examines the direct and indirect relationships between individual components of nutritional risk and increased severity of disability among a large and diverse sample of homebound older adults. Design and Methods: Using routinely collected nutrition and function data, structural equation modeling of recursive and nonrecursive models examined the interrelationships of nutritional risk factors, indicators of nutritional risk, and disability severity among 1,010 home-delivered meals program participants in Wake County, NC.
- Results: The equally good fit for both the recursive and nonrecursive structural models revealed that specific nutritional risk factors were directly and indirectly associated with indicators of nutritional risk and increased severity of disability.
- The nonrecursive model also revealed significant reciprocal associations of increased disability with unintended weight change and medication use.
Implications: The findings from this study acknowledge aspects of the complex direct and indirect relationships between nutrition and function among homebound older persons. This knowledge will help service providers with the development of effective elderly nutrition programs with nutritional and functional status outcomes.
Decision Editor: Laurence G. Branch, PhD Although subgroups of community-living older adults (namely women, the poor, Blacks, those with limited education, and the homebound) have been shown to be at increased risk for poor nutrition and functional disability (Coulston, Craig, and Voss 1996 ; Fried and Walston 1999 ; Institute of Medicine 2000 ; Ponza, Ohls, and Millen 1996 ; Quandt and Chao 2000 ; Sharkey and Haines 2001 ; Sharkey, Haines, and Zohoori 2000 ), there is a limited understanding of the interrelationship between components of nutritional risk and severity of disability.
The largest single nutrition program providing long-term home- and community-based care to older Americans is the Elderly Nutrition Program (ENP; Schlenker 1998 ). Even though this program serves vulnerable older adults in both group (congregate site) and home settings (home-delivered), dramatic changes in demographics are contributing to an ever-increasing demand for the home-delivered meal component of the ENP (Moyer and Balsam 1996 ; Ponza et al.1996 ; Schlenker 1998 ; Wellman 1999 ).
Accompanying this shift in demand are the emergence of a new ENP paradigm, with a focus on outcomes (both short- and long-term) that help older persons maintain adequate nutritional status and remain independent and at home (Wellman 1999 ), and two recent reports that suggest an association between nutritional risk and disability among home-delivered meal participants.
Both studies analyzed information that is routinely collected from ENP participants by the nutrition service providers: the Nutrition Screening Initiative’s (NSI’s) DETERMINE Checklist (NSI 1996 ), Activities of Daily Living or ADL (Katz, Ford, Moskowitz, Jackson, and Jaffe 1963 ), and Instrumental Activities of Daily Living or IADL (Lawton and Brody 1969 ).
One study, using categorical indicators for nutritional risk level and disability, which were derived from summary measures, reported that being at high nutritional risk increased the odds for severe disability (Sharkey and Haines 2001 ). A second study, using a categorical indicator for disability, found a direct association between specific nutritional risk factors and impairment in any self-care ADL (Sharkey and Haines 2000 ).
Little is known about the interrelationship between individual nutritional risk factors and increased severity of disability; and it is this understanding that can help move ENP services toward the development of effective ENP programs with nutritional and functional status outcomes.
- The conceptual model (see Fig.1) for the pathway from nutritional risk factors to disability was adapted from the work of Anderson and consists of three interrelated components: nutritional risk factors, indicators of nutritional risk, and the consequences of nutritional risk (Anderson 1990 ).
- Nutritional risk factors, which are extrinsic factors that influence nutritional status and place an older person at increased risk for poor nutrition, include multiple medications, social isolation /eating alone most of the time, oral/dental problems, difficulty in the preparation of meals, difficulty in shopping for groceries, economic status/lacking enough money for food, and having an illness or condition that caused a diet change (Goodwin 1989 ).
Nutritional risk factors are directly linked to indicators of nutritional risk (i.e., for poor dietary intake), such as eating few meals; consuming limited portions of fruits, vegetables, or milk products; and experiencing an unintentional weight change.
- One of the more severe consequences is functional disability, that is, requiring assistance in the performance of basic self-care tasks of daily living.
- Through the use of structural equation modeling of path analysis, the present study extends the nutrition and disability literature by examining the direct and indirect relationships between individual components of nutritional risk and increased severity of disability among a large and diverse sample of homebound older men and women.
By taking the total relationship (i.e., direct and indirect effects) between individual nutritional risk factors, indicators of nutritional risk, and disability severity into account, this may further extend the application of ENP routinely collected data and provide insight into potential areas of research and intervention common to both poor nutrition and functional decline.
What is another name for poor nutrition?
Malnutrition is a serious condition that happens when your diet does not contain the right amount of nutrients. It means “poor nutrition” and can refer to:
undernutrition – not getting enough nutrientsovernutrition – getting more nutrients than needed
These pages focus on undernutrition. Read about obesity for more about the problems associated with overnutrition.
How does poor nutrition impact the brain?
Healthy Meal, Happy Brain: How Diet Affects Brain Functioning Do you know that the foods you eat impact your health? Most importantly, what you eat can have negative effects on the most complex organ in your body: your brain! Amazingly, the food you eat affects neurons, which are the major cells of the brain.
In the brain, an unhealthy diet that is rich in fats and sugars causes inflammation of neurons and inhibits the formation of new neurons. This can affect the way the brain works and contribute to brain disorders like depression. On the other hand, a diet that contains healthy nutrients, such as omega-3 fatty acids, is beneficial for brain health.
Such a diet improves the formation of neurons and leads to improved thinking, attention, and memory. In sum, a healthy diet makes the brain happy, so we should all pay attention to what we eat. Like everyone, you may have wondered, “Why do my parents urge me to eat fruits and veggies and to stop eating junk foods?” The answer is, “You are what you eat!” What we eat can determine the composition and the activities of our cells.
A healthy diet with the proper amounts of nutrients should be eaten regularly, to keep our cells and organs– including the brain–healthy. The brain is the most complex organ of the human body. Throughout life, the brain monitors our daily operations and activities and communicates with other organs, coordinating their functions.
Brain cells called communicate with each other and with other organs, such as the muscles. For example, when you want to move your hand, the brain sends a message to muscles in the hand, telling them to contract. Neurons also communicate with other cells in the brain, called, which support the neurons.
- There are two types of glial cells: microglia and astrocytes.
- Microglia are the main immune cells of the brain, helping to protect the brain from infections.
- Astrocytes provide neurons with the nutrients they need to stay healthy.
- You can see that communication—both with other cells in the brain and with the rest of the body—is the brain’s most important job.
Messages sent by the brain not only allow us to perform physical tasks like moving around, but also help us to perform cognitive tasks. Cognitive tasks include actions like thinking, learning, remembering, memorizing, planning, imagining, organizing, and concentrating.
What are disorders of nutrition?
Nutrition disorders are diseases that occur when a person’s dietary intake does not contain the right amount of nutrients for healthy functioning, or when a person cannot correctly absorb nutrients from food. Nutrition disorders can be caused by undernutrition, overnutrition or an incorrect balance of nutrients.
