Sustainability messages and dietary advice need to be coordinated <\/p>\n
Health and nutrition guidance should be integrated with messages on reducing the diets environmental impact in order to ensure consistent advice, according to a new paper published inProceedings of the Nutrition Society. <\/p>\n
There has been much debate about quantifying the environmental impact of diet, especially in terms of meat and dairy consumption, with estimates of the proportion of global greenhouse gas emissions resulting from livestock ranging from about 10% to about 51%. Some experts have said that growing awareness of the environmental impact of dietary choices has been a major driver of vegetarianism and meat reduction among consumers. <\/p>\n
As part of a special edition in the journal focused on diet and environmental sustainability, Dr Jennie Macdiarmid of the Rowett Institute of Nutrition and Health in Scotland examined whether nutrition advice corresponded with messages about the environmental impact of dietary choices. <\/p>\n
She says that while consumption of plant-based protein has increased by 5% in the UK from 1990 to 2006, consumption of meat and protein from animal sources has also increased by 11%. <\/p>\n
Moving towards a more plant-based diet could have benets for health and the environment, but changing well established dietary habits dominated by animal-based products will not be easy, she wrote. <\/p>\n
Where health and sustainability collide <\/p>\n
She acknowledges that it is challenging to define what exactly constitutes a healthy diet, but previous research has suggested that a healthy, environmentally sustainable diet is possible without eliminating meat and dairy products. However, healthier diets do not always mean more sustainable diets, she said, and a specific conflict exists with recommendations for fish consumption and concerns about future fish stocks. <\/p>\n
Integrating guidance to reduce the environmental impact of the diet with dietary recommendations for health adds a level of complexity but addressing these issues together is essential to ensure clear and consistent dietary messages are given to consumers, Macdiarmid wrote, adding that efforts to increase sustainable fish supplies, for example, should be coordinated with dietary messages. <\/p>\n
