Two Serves of Seafood Per Week: A Key to Better Health, Research Shows

Dr. Joanna McMillan, a renowned nutrition scientist and dietitian, emphasizes a simple yet transformative habit for Australians – Two4Life.

New landmark research indicates that consuming seafood just twice a week can significantly reduce the risk of several major health issues in Australia. The findings stem from the most comprehensive review of seafood and human health ever conducted, highlighting the urgent need for Australians to embrace a simple habit called Two4Life.

Significant Health Benefits

According to the research, two serves of seafood weekly can:

• Reduce the risk of cardiovascular disease by 30%
• Lower Alzheimer’s risk by 30%
• Diminish the risk of dementia by 10%

In light of these findings, the Fisheries Research and Development Corporation (FRDC) has launched the Two4Life campaign, urging Australians to incorporate these two serves into their weekly routines.

A Simple Shift for Healthier Lives

Dr. Joanna McMillan states, “Two serves a week is achievable for nearly every Australian. It doesn’t require an expensive supplement regimen or a drastic dietary overhaul; it merely involves a minor, realistic adjustment that can contribute immensely to long-term health. Aim for two serves a week, ensuring at least one is an oily fish to maximize omega-3 benefits.”

She continues, “The beauty of seafood is its accessibility. Whether fresh, frozen, or from various species, all seafood counts toward your weekly goal.”

Tips to Get Started

Here are three easy ways to incorporate seafood into your meals:

• Replace one weekly lunch and one weekly dinner with seafood options—think grilled fish, prawns, or tuna in pastas, tray bakes, or tacos.
• Keep a stock of frozen seafood for quick midweek meal solutions.
• Explore different varieties—options like mussels, pipis, prawns, and sardines are affordable and easy to prepare.

Supporting Australia’s Seafood Sector

FRDC Managing Director Sean Sloan emphasizes, “Australia’s sustainable seafood sector underscores that two serves a week is not only feasible but also backed by a reliable, high-quality supply that Australians can trust. Whether wild-caught or farmed, there is an impressive range of seafood options that suit every budget.”

Broader Implications for Health

The benefits of seafood consumption extend beyond cardiovascular and cognitive health. Omega-3 fatty acids help in reducing inflammation, improving blood vessel function, and maintaining brain structure. For older adults, seafood can prevent muscle loss and frailty, making it vital for healthy aging.

Additionally, higher seafood intake has been associated with a 26% lower risk of depression in adults who consume regular servings.

The Unmatched Nutritional Value of Seafood

In today’s world of dietary supplements, the takeaway is clear: no supplement can replicate the health benefits of seafood. The unique combination of omega-3s, protein, vitamin D, B12, iodine, selenium, and zinc in seafood works synergistically in ways that isolated supplements cannot.

Lead researcher Dr. Wendy Hunt from Murdoch University asserts, “Eating two serves of seafood a week, particularly one high in omega-3s, as part of a healthy diet, yields significant health benefits throughout our lives, from preconception onward.”

Professor Alexandra McManus from Curtin University adds, “This simple dietary change is not only easy to achieve but also affordable, as a single serving is merely 100-150 grams.”
