Dietary portfolio approach to reducing the risk of cardiovascular disease: The Polymeal revisited

摘要

Aims: The Polymeal was first proposed as a 'tastier and safer' alternative to a polypharmacy approach to cardiovascular disease risk reduction. The present study aimed to examine the affordability of the Polymeal, and to propose modifications based on economic considerations, and the latest scientific evidence, to achieve consistency with current public health recommendations.Methods: Prices for each food component specified in the Polymeal were obtained from a major and independent supermarket chain in a representative middle socioeconomic demographic region of metropolitan Melbourne, Australia. Items included fish (114 g, four times/week), fruits and vegetables (400 g/day), dark chocolate (100 g/ day), garlic (2.7 g/day), almonds (68 g/day) and red wine (1 50 mL/day). Prices were calculated using an average of the major brands, or the most commonly eaten fruits, vegetables or fish. Modifications of the Polymeal were proposed based on published research and public health recommendations since the Polymeal was first proposed. Results: Average price of the Polymeal was AUDollars 11.89 per day falling to AUDollars 8.46 if the cheapest food items were chosen. Modifications to the Polymeal included: consuming fish oil capsules instead of fish, reduction in the quantity of dark chocolate and removal of red wine. These modifications halved the cost of the Polymeal, while choosing the cheapest food items further lowered the cost to AUDollars 3.49 per day. Modification of the Polymeal gave substantial reductions in both energy and saturated fat (51% and 84%, respectively).Conclusion: The modified Polymeal is a more affordable variation of the Polymeal, which takes into account current scientific evidence and public health recommendations.
