Guideline 3


Infants


For infants under the age of around 6 months, breast milk provides an ideal amount and type of fat. The guideline
recommendation on fat intake for the adult population does not apply to young children, particularly those
aged less than 2 years. The amounts and types of fat required for infants are related to physiological and health
outcomes.^8 Even a small energy deficit during this period of rapid development may affect growth.^8 Neurological
development is particularly rapid in the first 2 years of life and restriction of the fat intake during that time may
interfere with optimal energy intake and reduce the supply of essential fatty acids, particularly omega-3 lCPuFAs
needed by developing nervous tissue, adversely affecting growth and development.


Children and adolescents


Reduced fat milk is recommended from the age of 2 years, when milk plays a less dominant role in the diet.
A high-fat diet is likely to be energy-dense, contributing to excess energy intake and the development of obesity.
Even at a young age, a diet high in saturated fats may predispose children and adolescents to the development of
cardiovascular disease later in life and the evidence supports this advice on fat intake for children from 2 years of
age.35,719 Introducing healthy eating patterns in early childhood influences dietary patterns in later childhood.720,721


Older people


low fat diets are not suitable for convalescent older people and frail elderly people (to whom these Guidelines
do not apply) because of the possible adverse effects of energy restriction in these groups. However, for those
aged 65–75 who are well, the type and amount of fat in the diet deserves consideration. Although the increased
relative risk of raised plasma cholesterol for coronary heart disease tends to be lower in older people than in
younger adults, lowering lipid levels can reduce risk of ischaemic heart disease regardless of age.^722


Aboriginal and Torres Strait Islander peoples


limiting intake of excess energy from any source, including foods high in fat, is particularly important given
the higher prevalence of obesity in Aboriginal and Torres Strait Islander groups compared to non-Indigenous
Australians.28,30 limiting saturated fat and increasing unsaturated fats are important given the high prevalence
of coronary heart disease, and decreased saturated fat intake may also improve insulin sensitivity.


People from culturally and linguistically diverse groups


The profile of dietary fat will vary depending on traditional culinary use. Food product labels may assist people in
learning about the amounts and types of fats in unfamiliar or newly introduced manufactured foods.


3.2 Limit intake of foods and drinks containing added salt


3.2.1 Setting the scene


Dietary guidelines have recognised the role of sodium in elevating blood pressure since the uS Surgeon General’s
report released in 1979.^723 Initial advice to the public was framed to reduce consumption of discretionary salt, such
as salt added at the table or during cooking. However, sodium occurs naturally in food, and sodium-containing
additives are also added to manufactured and processed foods. It is now recognised that processed foods are the
major source of sodium in Western diets. In these Guidelines, ‘salt’ refers to sodium chloride and is never used as
a synonym for the total amount of sodium in foods.


Since the 2003 edition of the dietary guidelines, the evidence for a relationship between reducing sodium intake
and reducing blood pressure has strengthened, particularly in people classified as having normal blood pressure.
In addition, there is now some evidence indicating that reducing sodium may result in a reduction in mortality,
stroke and heart disease for those with hypertension, but not, as yet, for those with normal blood pressure.
