Environmental and Agricultural Health

Environmental health relates dietary choices to their impact on energy use in producing and transporting food, greenhouse gas emissions, pollution, and agricultural sustainability.

Is a healthy diet an environmentally sustainable diet?

The concept of a healthy and environmentally sustainable diet is not new, but with increasing concern about future global food security and climate change there is a renewed interest in this topic. Dietary intakes in UK accounts for approximately 20-30% of total annual greenhouse gas emissions (GHGE), with the greatest contributions coming from high intakes of meat and dairy products. Dietary proposals to help mitigate climate change (i.e.

Embodied greenhouse gas emissions in diets

Changing food consumption patterns and associated greenhouse gas (GHG) emissions have been a matter of scientific debate for decades. The agricultural sector is one of the major GHG emitters and thus holds a large potential for climate change mitigation through optimal management and dietary changes. We assess this potential, project emissions, and investigate dietary patterns and their changes globally on a per country basis between 1961 and 2007.

Relation between vegetarian/nonvegetarian diets and blood pressure in black and white adults.

We examined the possible interaction of race and diet on blood pressure (BP) in volunteer Black Seventh Day Adventists compared to volunteer White church members. Height, weight, waist and hip circumference, and resting seated BP were recorded in Black vegetarians (n = 55; age: 54.7 +/- 16.9 yrs), Black nonvegetarians (n = 59; 56.1 +/- 14.1 yrs), White vegetarians (n = 164; 52.2 +/- 16.7 yrs), and White nonvegetarians (n = 100; 52.6 +/- 15.6 yrs) attending a regional conference.

Ecology and vegetarian considerations: does environmental responsibility demand the elimination of livestock?

Although the recommendation to avoid animal flesh for environmental reasons has been increasingly advanced, especially in the highly industrialized countries, the ecological implications of such avoidance are seldom carefully examined. If sustainable food systems are to be modeled after natural systems that maintain fertility, both plants and animals would be involved. This paper examines the history of the idea that environmental responsibility is linked to vegetarianism and the destructive effects of present methods of animal raising on farmers, animal welfare, and the environment.

Nutrition ecology: the contribution of vegetarian diets.

Nutrition ecology is an interdisciplinary scientific discipline that encompasses the entire nutrition system, with special consideration of the effects of nutrition on health, the environment, society, and the economy. Nutrition ecology involves all components of the food chain, including production, harvesting, preservation, storage, transport, processing, packaging, trade, distribution, preparation, composition, and consumption of food, as well as disposal of waste materials. Nutrition ecology has numerous origins, some of which go back to antiquity.
