Ask adults how many portions of fruits or vegetables they eat in a day and advise to follow the NHMRC’s Australian dietary guidelines (B).85 Brief advice should be given to eat two serves of fruit and five serves of vegetables per day (2 + 5 portions), and to limit sugar, saturated fat, salt and alcohol.

Breastfeeding should be promoted as the most appropriate method for feeding infants (and one that offers protection against infection and some chronic diseases).85 Refer to Chapter 3. Preventive activities in children and young people for nutrition-related recommendations.

What should be done?

How often?

Average risk

Adults9,86

Ask about the number of portions of fruits and vegetables eaten per day, and the amount of sugar (including sweetened drinks), salt and alcohol, and saturated fat intaked (II, B) 

All patients should be advised to follow the Australian dietary guidelines and eat at least five serves of vegetables and two serves of fruit per day (II, B)

Every two years (IV, D)

Children and adolescents85

Assess growth using the World Health Organization (WHO) weight-for-age and height-for-age charts up to 2 years of age, and body mass index (BMI) for age charts from 2 to 16 years of age 

Advise patients to follow Australian dietary guidelines, including eating high quantities of vegetables, fruit, wholegrain cereals, poultry, fish, eggs and low fat milk, yoghurt and cheese products, and less discretionary food choices including sugary soft drinks

At times of child health surveillance or immunisation until 5 years of age then every two years

High risk85,87

  • Overweight or obese
  • High cardiovascular disease (CVD) absolute risk (>15%)
  • A past or first-degree family history of CVD (including stroke) before 60 years of age. For personal history the age does not matter
  • Type 2 diabetes or high risk for diabetes

Provide lifestyle advice to limit intake of foods containing saturated fat, added salt, added sugars (including sugary drinks) and alcohol, and increase serves of fruit and vegetables. (Refer to Section 7.2. Overweight for dietary recommendations for overweight and obesity; II, B) 

Provide self-help nutrition education materials and refer to a dietitian, group diet program or phone coaching (II, B)

Every six months (Practice Point)

Intervention

Technique

Vitamin supplements

Vitamin supplementation is not of established value in asymptomatic individuals* (with the exception of folate and iodine in pregnancy). Routine screening for vitamin D deficiency is not recommended in low-risk populations85

Dietary recommendations

Enjoy a wide variety of foods each day, including:85

  • five serves of vegetables (of different types and colours, and legumes/ beans) and two serves of fruit
  • grain or cereals (mostly wholegrain and/or high fibre varieties such as breads, rice, pasta, noodles, polenta, couscous, oats, quinoa and barley)
  • lean meats, fish, poultry, eggs, tofu, nuts and seeds

and

  • drink plenty of water88

Take care to:

  • limit saturated fat and reduce salt
  • limit alcohol intake
  • avoid sugary beverages including soft drink and limit fruit juices
  • limit sugars and foods containing added sugars
  • limit red meat (three to four times per week) and limit or avoid
  • processed meat
  • care for food: prepare and store it safely
  • encourage and support breastfeeding

For specific advice, especially patients with specific conditions, refer to a dietitian 

The National Heart Foundation of Australia has a number of nutrition position statements 

In children, overweight or obesity is associated with sweet drink consumption, and dental problems are associated with consumption of fatty foods and sweet drinks89

Encourage breastfeeding

Encourage and support exclusive breastfeeding until 4 to 6 months of age (there is current controversy about when to introduce foods; refer to Practice Point c in Table 3.2). It is recommended that breastfeeding continue until 12 months of age and thereafter as long as is mutually desired85

*Prevalence of nutritional deficiency is high in certain groups, such as people with alcohol dependence and the elderly living alone or in institutions.
