What is Nutrition?
Why Is Nutrition Important?
What is Nutrition?
Nutrition is the intake of food, considered in relation to the body’s dietary needs (WHO)
The process of nourishing or being nourished
The History of Nutrition
To stimulate the brain we will continuously ask questions
How Long Have We Been Aware of Nutrition?
400 B.C. -- Hippocrates, the "Father of Medicine", said to his students, "Let thy food be thy medicine and thy medicine be thy food". He also said “A wise man should consider that health is the greatest of human blessings.”
1747: Dr. James Lind, a physician in the British Navy, performed the first scientific experiment in nutrition discovering the treatment of scurvy

Benefits of Good Nutrition
How is malnutrition affecting people
worldwide?
Malnutrition
Undernourished Vs Overnourished
Global Look at Malnutrition
Undernutrition indicates a lack of the
necessary energy, protein or micronutrients required by the body for good health
Occurs when people do not eat or absorb enough nutrients to cover their needs for energy and growth or to maintain a healthy immune system
Most basic kind- Protein-energy malnutrition
Micronutrient deficiency occur when the body lacks one or more micronutrients resulting in deficiencies which usually affect growth and immunity e.g. anaemia (iron deficiency)
Undernutrition
Causes of undernutrition
Lack of info/
knowledge
Fad diets
Disease and illness
Changes in requirements throughout
lifecycle
Poverty/ lack of
access to food
Poor diet
Causes of Undernutrition
Unplanned weight loss (usually losing more than 5-10% of your body weight within three to six months)
Weak muscles and/or loss of muscleFeeling tired all the time Low mood Increase in illnesses or infectionsSlow recovery from illness Failure to grow at the expected rate Changes in behaviour such as appearing
unusually irritable, sluggish or anxious
Signs of Malnutrition
Prevalent in, but not limited to, developing countries
842 million people in the world do not eat enough to be healthy.
1 in 8 people on Earth go to bed hungry each night.
WHO estimate Undernutrition contributes to 1/3 of all child deaths (2010)
How Common is Undernutrition
Iron Deficiency Anaemia
Infants > 6months and toddlersMenstruating womenPregnant womenVegetariansDiets lacking in Vitamin CPeople with malabsorption or
pathological blood loss
Obesity
Type 2 Diabetes
Cardiovascular disease
Over Nutrition
Obesity
Obesity

were obese35% of adults aged 20 and over were overweight in
2008 and 11% were obese65% of the world’s population live in countries
where overweight and obesity kills more people than underweight
42 million children under the age of 5 were overweight or obese in 2013

Implications of Obesity
Type 2 Diabetes
2
347 million people worldwide suffer from Diabetes
More than 80% of diabetes deaths occur in low- and middle-income countries
WHO projects that diabetes will be the 7th leading cause of death in 2030
Healthy diet, regular physical activity, maintaining a normal body weight and avoiding tobacco use can prevent or delay the onset of type 2 diabetes
Diabetes is a Global Issue
What is Diabetes?
2
Type 1 Diabetes Type 2 Diabetes
Failure of cells to produce insulin 90% of all diabetes cases (WHO)
Autoimmune basis Decreased insulin produced or insulin resistance
Develops suddenly Strongly linked to obesity
In children or adults <40 Genetic predisposition
Treatment with insulin! Gradual onset usually in adults
Treat with diet and lifestyle Higher prevalence in African Caribbean and Asian origin

What is Cardiovascular Disease?

In 2008- 17.3 million people died from CVDs, 30% of all deaths that year
2030: CVD related deaths will increase to 23.3 million people/year
