Dietary recommendations

breadFor women aged 40 and over dietary recommendations include general food guidelines, such as The Australian guide to healthy eating, and specific nutrient recommendations, as outlined in the Recommended dietary intakes for use in Australia. Recent advances in nutritional science and research have prompted review of recommended dietary intakes (RDIs), and this may result in future recommendations for novel food components such as phytoestrogens and antioxidants.

Currently, RDIs for adult women are divided into two age groups 19-54 years and over 54 years.

RDIs for women over 54 years more closely reflect the needs of women aged 40 and over, particularly menopausal women.

†The wide variation in serves is because of individual variation in activity.

‡In addition to the 1-2 serves of extra foods, the guide also recommends modest consumption of margarine on foods like bread and toast and modest amounts of margarine or oil in food preparation.

Zinc and Calcium

The National Nutrition Survey (NNS) showed that mean intakes of zinc and calcium in women aged 45-64 years were below RDIs. Their mean fibre intake of 21g per day was also below the suggested daily intake (30g). Lower intakes of calcium, zinc and fibre in these women correlate with a low intake of breakfast cereals, milk, yoghurt, cheese, fruit, vegetables, fish and seafood, which are good sources of these nutrients.

Mean intake of breakfast cereals was 12.2g per day, much less than a standard serve of 30-45g. Mean daily intakes of fruit of 1.1 serves and vegetables of 3.4 serves were below recommended intakes of two serves of fruit and five of vegetables daily.6 Mean intakes of calcium-rich foods such as milk, yoghurt and cheese were all less than a standard serve per day, which might explain why this group’s calcium intake fell short of the RDI, achieved by eating a minimum of 3-4 serves of dairy foods daily. Intake of fish was low (only 12g per day) compared with the National Heart Foundation’s recommendation of at least two fish meals per week (standard serve of 80-120g).

Dietary factors and breast cancer risk have been extensively researched. Women with greater dietary intakes of vitamins A, C and E, and fibre, have a reduced risk of breast cancer.9,10 Large intakes of the antioxidant vitamins A, C and E, taken as supplements, do not appear to protect against breast cancer in women whose dietary requirements of these vitamins are met. Further, vitamin A supplements have been associated with a reduction in breast cancer risk among women who have very low vitamin A intake from food, but not for women with an adequate dietary intake.11 Dietary fibre interferes with the enterohepatic circulation of oestrogen metabolites in bile, so that reabsorption and hence recycling of endogenous oestrogen is reduced.12 However, the inverse relationship between vegetable intake and breast cancer risk is not explained by any single dietary factor. The multiple nutrients in vegetables may have a synergistic effect on breast cancer risk, or other, unidentified components may influence risk.13

Alcohol consumption is associated with a linear increase in breast cancer incidence, and it has been proposed that a reduction in alcohol consumption by women who consume alcohol regularly may reduce breast cancer risk.13

Given the high prevalence in Australia of overweight and obesity in women aged 40 and over, and the lower than recommended intake of some important foods and nutrients, women in this age group should be encouraged to follow The Australian guide to healthy eating. Specifically, more emphasis needs to be placed on a diet low in saturated fat, with more breads, cereals, fruits and vegetables, and more calcium-rich foods, as well as maintaining a healthy body weight by balancing food intake and regular physical activity.


Many Australian women over 40 years consume insufficient zinc, calcium and fibre. Greater consumption of foods rich in vitamins A, C and E and fibre is associated with a lower risk of breast cancer. Concentrated supplements of A, C and E have no effect on breast cancer risk when dietary intake is adequate, but vitamin A supplementation in women whose dietary intake of vitamin A is inadequate appears to reduce the risk of breast cancer. Alcohol consumption by women has been associated with a linear increase in breast cancer risk.
