INFO SHEET - Functional foods -  Functional food is any processed food claimed to have a health-promoting or disease-preventing property that goes beyond the basic macronutrient and micronutrient functions.  Common examples are:  omega-3 fish oil-enriched breads plant sterol and stannol-enriched margarines yoghurt enriched with probiotic bacteria calcium-enriched milk caffeine-enriched beverages like coffee.

INFO SHEET - Micronutrients -  Micronutrients are substances such as vitamins and minerals that are necessary dietary components. Although needed in only small amounts, they are essential for health and wellbeing. The consequences of their absence are severe, impacting in particular on children’s physical growth, mental development and immune function.

In this video clip, Carolyn Cairncross, a nutritionist with the New Zealand Nutrition Foundation, describes some of the key components that should be included in the adolescent diet. She also provides advice on healthy eating practices such as eating plenty of fresh fruit and vegetables, keeping the body in a well hydrated state, not skipping meals and avoiding energy drinks high in caffeine.

NEWS STORY (2012) No nonsense list of foods -  Consumers are often confused by misleading dietary claims made by food manufacturers. Researchers from the University of Otago in Christchurch have published a list of 49 foods that they describe as NEEDNT (non-essential, energy dense, nutritionally deficient) foods.

Foods rich in fibre include whole wheat, bran, fresh or dried fruits and vegetables. Fibre is an important ingredient of a healthy diet.

Water content of foods - In this activity, students quantitatively analyse carrot and banana for moisture content and total solids using and comparing two drying methods.

Cruciform vegetables like cabbage have a high phytochemical content. It is estimated that 1 serving of cabbage could supply, in very small amounts, up to 100 different phytochemicals.

Phytochemicals are naturally occurring, biologically active chemical compounds in plants. The prefix ‘phyto’ is from a Greek word meaning plant.

INFO SHEET - Dietary fibre -  Dietary fibre is the portion of fruits, vegetables, nuts and grains we eat that is resistant to digestion and absorption in the small intestine. However, bacteria that live in the large intestine may digest part of it.

Whole grains retain their healthy fiber, fats, vitamins, protein and minerals. Unrefined grains do not. That is why it is so important to know the difference between the two.
