  • Poor nutrition can lead to: reduced immunity, increased susceptibility to disease, impaired physical and mental development, reduced productivity
  • Nutrition and food are fuel
  • The benefits of good nutrition are numerous: boost the immune system, improve sport performance, delays ageing, protects teeth and gums, enhanced concentration, fights and prevents disease, energy for life, keeping a healthy weight
  • Nutrition and foods are not always good
  • Malnutrition (over and under nutrition) are huge problems globally
  • Under nutrition – indicates a lack of the necessary energy, protein or micro nutrients required by the body for good health e.g. protein-energy malnutrition
  • Micronutrient deficiencies occur when the body lacks one or more micro nutrients resulting in deficiencies which usually affect growth and immunity e.g. anaemia (iron deficiency)
  • Causes of under nutrition: lack of knowledge, fad diets, disease and illness, life cycle changes, poverty, inadequate diets…
  • Signs of under nutrition:

o Unplanned weight loss

o Weak muscles and/or loss of muscle

  • 842 million people globally, mostly in developing countries suffer from under nutrition and 1 in 3 child deaths are related to under nutrition
  • Iron deficiency anemia can occur when the body has a lack of red blood cells or hemoglobin to transport oxygen to the cells of the body – most common cause lack of iron in the diet
  • Consequences include: fatigue, dizziness, rapid heartbeat, pallor and breathlessness
  • Those at risk include: Infants > 6months and toddlers, menstruating women, pregnant women, vegetarians, diets lacking in Vitamin C, people with malabsorption or pathological blood loss
  • Iron rich foods include: dark leafy greens, eggs yolks, broccoli, poultry, quinoa, red meat, shellfish, grains, dried fruits, lentils

Cardiovascular Disease

  • Cardiovascular disease is a group of disorders of the heart and blood vessels and is the number 1 killer globally.
  • Risk factors include: unhealthy diet, physical inactivity, tobacco use, excessive alcohol, genetics,
  • An unhealthy diet + an inactive lifestyle can lead to elevated blood pressure, blood glucose and blood lipids as well as overweightness or obesity. This can indicate an increased risk of developing a heart attack, stroke of heart failure
