Nutrient intake in excess of the RNI’s may reduce the risk of developing chronic diseases. Specifically, a higher intake of Vitamin C, E, A (particularly β-carotene), selenium, folate, omega 3 and dietary fibre may be benficial. The Australian & New Zealand National Health and Medical Research Council have published a second set of guidelines known as "Suggested Dietary Targets (SDT's) to optimise dietary intake for reducing the risk of chronic disease”. These SDT’s have been incorporated into the Nutritics DRV source only. Where no target intake has been set by in the SDT’s, the highest RNI has been taken from all International sources combined. Furthermore, the highest safe upper intake and the highest LRNI from all International sources has been set as upper and lower RNI’s on the Nutritics source.
The macronutrient recommendations provided in the Nutritics option are adopted from International Sports Nutrition guidelines, including the American College of Sports Medicine and American Dietetics Associations position stand on Nutrition and Athletic Performance, ISSN and Australian Institute of Sport:
These are provided as guidelines only; exact requirements will vary from person to person depending on factors such as training intensity, training duration, available recovery time, and fitness status.
The guidelines for pregnancy come from the UK Scientific Advisory Committee on Nutrition (SACN) and the National Health and Medical Research Council (NHMRC) in Australia.
