We’re Still Eating The Wrong Things

August 23, 2019 By EarthWise 1 Comment

A new study published in the Journal of the Academy of Nutrition and Dietetics has found that despite efforts to increase public awareness of health issues related to diet, the amount of processed meat consumed by Americans has remained unchanged in the past 18 years. Furthermore, our intake of fish and shellfish has not increased. One quarter of US adults are still eating more unprocessed read meat than the recommended level, and less than 15% meet the current guidelines for fish and shellfish consumption.

About the only positive note is that Americans are eating less beef and more chicken than they did 18 years ago and, in fact, for the first time, the consumption of poultry exceeds that of unprocessed red meat.

Accumulating evidence has linked excessive consumption of processed meat to increased risk of obesity, diabetes, cardiovascular diseases, and some cancers. The study’s authors speculate that public awareness of these linkages is not widespread enough to affect change and, in any case, factors other than health – social, cultural, and economic – have greater influence over Americans’ food choices. The top five consumed processed meats are luncheon meat, sausage, hot dogs, ham, and bacon.

The low consumption of fish and shellfish among U.S. adults could be due to high retail prices, lack of awareness of the health benefits, and concerns about mercury contamination in certain types of fish.

Future research is needed to identify barriers to reducing processed meat consumption and increased seafood consumption. Policies such as nutrition quality standards, excise taxes, health warning labels, and other interventions need to be explored.

Why Choose Chicken Over Beef?

July 22, 2019 By EarthWise Leave a Comment

Food production is a major driver of climate change. It’s responsible for more than a quarter of all greenhouse gas emissions. But the environmental impact of different foods varies greatly, and making seemingly insignificant changes can actually have significant impacts.

According to a first-ever national study of U.S. eating habits and their carbon footprints, choosing chicken over beef will cut your dietary carbon footprint in half.

The National Health and Nutrition Examination Survey asked more than 16,000 participating Americans to name all the foods they consumed in the past 24 hours. The research team then calculated the carbon footprint of what people said they ate. If a respondent consumed broiled beef steak, for example, researchers calculated what the carbon footprint would have been had broiled chicken been consumed instead.

The study’s findings illustrate how making one simple substitution can significantly reduce a person’s dietary carbon footprint. A diet’s carbon footprint is the amount of greenhouse gas emissions that result from the energy, fertilizer, land use, and other inputs necessary to produce food.

In general, animal-based foods have a bigger carbon footprint than plant-based foods. For example, producing beef uses 20 times the land and emits 20 times the emissions as growing beans (per gram of protein), and requires 10 times more resources than producing chicken.

According to the World Resources Institute, keeping the increase in global warming below 2°C will be impossible without limiting the global rise in meat consumption.

Last year, the EAT-Lancet Commission report found that a radical transformation of the global food system was needed because it’s threatening the stability of the climate.

Make a change – big or small – today.

Food Production And Climate Change

January 29, 2019 By EarthWise Leave a Comment

According to a University of Oxford study recently published in the journal Science, food production is a major driver of climate change as it’s responsible for 26% of all greenhouse gas emissions. But the research team found that the environmental impact of different foods varied greatly.

Meat and other animal products are responsible for 58% of all food-related greenhouse gas emissions, despite only providing approximately one-fifth of the calories we consume. The researchers found that beef and lamb in particular have the most damaging effect on the planet, responsible for half of all greenhouse gas emissions from animal agriculture.

These findings echo recommendations from the Intergovernmental Panel on Climate Change about how individuals can reduce their carbon footprint through diet. The IPCC suggests we consume less meat and dairy products, consume more locally-sourced seasonal foods, and throw less food in the trash.

Avoiding meat and dairy products can reduce an individual’s carbon footprint from food by two-thirds. The effects of doing so include everything from conserving water and preserving biodiversity to reducing pollution and deforestation.

Interestingly, the same food can have major differences in terms of environmental impacts. For example, beef raised on deforested land is responsible for 12 times as many greenhouse gas emissions as that raised on natural pastures. But even the most climate-friendly meat options are still responsible for more greenhouse gas emissions than the highest-impact vegetable proteins, like beans and nuts.

Big differences can also be made by avoiding chocolate and coffee produced from deforested lands.

Big Changes To Big Poultry

July 19, 2016 By WAMC WEB

Perdue Farms, the fourth-largest poultry producer in the United States, produces over 60 million pounds of chicken a week. They are arguably the most progressive of the giant poultry companies. Two years ago, they were the first to renounce routine antibiotic use. In late June, they announced a comprehensive animal-welfare plan – the first among large producers – that will change how its chickens are bred, raised and killed.
