• the behavioural principles are modelling, exposure, and repetition
• behavioural principles can help to establish healthy food habits in the home and assist in creating a positive environment around food and food preparation
• Key behavioural principles

  • Exposure
  • Modelling
  • Repetition
• Physiology

  How the body and its parts work
• Microbiology


  Study of microscopic organisms
• Food digestion


  1. Mechanical digestion

  2. Chemical digestion
• Chemical digestion


  Food is broken down by the action of chemical agents (such as enzymes, acids and bile)
• Mechanical digestion


  Food is physically broken down into smaller fragments via the acts of chewing (mouth), churning (stomach) and segmentation (small intestine)
• Absorption


  How the nutrients are absorbed by the digestive system. Where this occurs is different depending on the macronutrient.
• Utilisation


  How the body uses nutrients
• Enzymatic hydrolysis


  The process in which enzymes break the bonds in molecules with the addition of water. This is an important role in the digestion of food.
• Modelling


  The behaviour where parents and/or carers demonstrate nutritious eating habits. Modelling can be intentional or unintentional.
• Exposure


  The action of continually introducing foods and experiences around healthy and nutritious food for children.
• Repetition


  Being offered the same healthy foods a number of times, creating a familiarity with nutritious foods.
• mindless eating is Consuming foods without full awareness or conscious thought on the process
• Variables that impact children’s eating behaviours. 1) dislike and food refusal

  2) food intake

  3) food choice

  4) food preference

  5) willingness to try food
• We have seen an increase in food delivery services over recent years. This can be a cause for overconsumption because foods that may not be needed to satisfy hunger are ordered and consumed, leading to an excess in energy intake.
• An example of sedentary behaviour in our food systems is the rise in home delivery of food services from our grocery shopping to our takeaway dinners.
• Overconsumption refers to food intake and energy requirements exceeding what is required by the body for functioning and energy expenditure
• Sedentary behaviour is a state in which body movement is minimal, such as sitting time while watching television
