Study Notes

Malnutrition Map

According to WHO, malnutrition is a significant global issue
The World Life Expectancy website provides a map of malnutrition by country

Causes of Malnutrition

Famine: shortage of food and variety leading to starvation and lack of nutrients
Poverty: socio-economic status affecting access to nutritious food, leading to malnutrition
War: disrupts food supply and transport links, leading to malnutrition
Child/teenage pregnancy: removal of nutrients by the fetus can lead to malnutrition
Lack of variety in diet: weight loss diets, eating disorders, and psychological issues can lead to malnutrition

Nutritional Deficiencies and Obesity

Micronutrient deficiencies can promote obesity and Type 2 diabetes
Iron deficiency can be caused by iron chelators like calcium, and can be enhanced by Vitamin C-rich foods
Incomplete proteins can be found in non-animal sources and need to be combined to get a complete set of amino acids

Malnutrition Definition and Types

Malnutrition: getting too little or too much of certain nutrients
Undernutrition: not getting enough protein, calories, or micronutrients, leading to low weight-for-height, height-for-age, and weight-for-age
Overnutrition: overconsumption of certain nutrients, leading to overweight or obesity

Prevalence of Malnutrition

Malnutrition is a leading cause of death, with varying rates across the world (e.g., 0.56/100,000 in the U.S.A, 0.1/100,000 in the UK, and 121.11/100,000 in Central Africa)
In 20 African countries, under-5 years old showed stunting, women of reproductive age showed anemia, and adults showed obesity/overweight

Effects of Nutritional Deficiencies: Protein

Kwashiorkor: enough calories but lacking in protein (essential amino acids), leading to oedema and liver damage
Marasmus: too little protein and too few calories, leading to muscle wasting and undernutrition
Complete proteins contain all essential amino acids and can be found in meat, fish, eggs, and milk
Incomplete proteins contain only some essential amino acids and can be found in leafy vegetables, beans, and grains
