A recent study published in The Journal of Nutrition has shed light on the impact of diet on the longevity of Australian women. The study, which analyzed data from 9,584 women enrolled in the 1946–1951 cohort of the Australian Longitudinal Study on Women’s Health (ALSWH), revealed that women who adhere to healthy eating patterns are 40% more likely to live until their mid-to-late 70s compared to those with poorer diets.
The research, conducted by The George Institute for Global Health and the University of Newcastle, Australia, found that diets aligned with current Australian Dietary Guidelines or a Mediterranean-style diet were associated with a lower risk of death from any cause. The study spanned over 17 years, with participants aged 74–79 at the time of data collection.
Lead author Dr. Briar McKenzie emphasized the importance of following a diet rich in lean proteins, fruits, vegetables, whole grains, and pulses for overall health and longevity. The study highlighted the need for more research focusing on the specific health outcomes of women, as well as the impact of diet on diseases such as heart disease and dementia.
Co-author Professor Clare Collins emphasized the importance of cooking fresh food at home and cautioned against falling for fad diets or unproven supplements. She recommended aligning dietary patterns with the general principles of the Australian Dietary Guidelines or a Mediterranean-style diet for optimal health.
The study also raised concerns about the increasing prevalence of obesity and diet-related diseases among Australian women. The researchers called for more support from the food industry and government to promote healthy eating habits, especially among women who are often the main decision-makers when it comes to nutrition for their families.
As the Australian Dietary Guidelines are currently under review, the study suggested a focus on women’s dietary needs across their life-course, rather than just during reproductive stages. The study population’s leading causes of death were identified as breast cancer, lung cancer, cardiovascular disease, and dementia, highlighting the importance of addressing diet-related risk factors.
Overall, the study provides valuable insights into the link between diet quality and longevity in Australian women, emphasizing the need for tailored nutrition advice and support to promote healthy eating habits and prevent diet-related diseases.
