The fast-growing economies of China and India are driving a global increase in meat consumption, cancelling out decreases elsewhere, according to a comprehensive study of global food consumption.
The work, published today in Proceedings of the National Academy of Sciences, takes a detailed look at what people eat, as well as trends from one country to the next. It is also the first time that researchers have calculated humanity’s trophic level, a metric used in ecology to position species in the food chain.
The metric puts plants and algae, which make their own food, at trophic level 1. Rabbits, which eat plants, occupy level 2. Foxes, which eat herbivores, sit at trophic level 3. Cod, a fish that eats other fish, claims level 4. Polar bears and orcas, which have few or no predators and eat other mammals with gusto, hold the top positions — levels up to 5.5.

On Monday, researchers at the Harvard School of Public Health released study results showing that red meat consumption was associated with a higher risk of early death. The more red meat — beef, pork or lamb, for the purposes of the research — study participants reported they ate, the more likely they were to die during the period of time that data collection took place (more than 20 years). So what is it in red meat that might make it unhealthy?
