Experts in diet and nutrition are concerned with the role of food and drink in good health and disease. Experts in this area may be medical doctors or trained dietitians who have specialised in the fields of nutrition and diet.

Areas of interest and study in this field include:

  • Gastroenterology
  • Allergies
  • Diabetes
  • Metabolism

Diet and poor nutrition are staples in the news with obesity and diabetes being major and growing health concerns, especially in socioeconomically deprived areas. Poor nutrition can impair our daily health and wellbeing and reduce one’s ability to lead an enjoyable and active life.

In the short term, poor nutrition can contribute to stress, tiredness and reduced capacity to work, and over time, it can contribute to the risk of developing some illnesses and other
health problems such as:

  • obesity
  • tooth decay
  • high blood pressure
  • high cholesterol
  • heart disease and stroke
  • type-2 diabetes
  • osteoporosis
  • some cancers
  • depression
  • eating disorders.

They may be able to comment on food-related policy, healthy policies, and how food may have contributed to particular health outcomes. These experts may be further particularly useful in matters relating to allergies, intolerance, and other medical conditions arising from negligent food preparation.
