How Do You Fancy a Diet of Healthy Bugs?

This is a news article I read recently online. I am providing the full news link, together with a section of the original article below, I believe you will find this interesting, whether in a light-hearted or serious mindset.

It may sound a little jovial and speculative for the time being, but there are many countries where insects already form a good portion of a normal dietary intake. At the moment I don't think we should all rush out to buy our weekly supply of bugs... but perhaps just use this to think about what we are eating, where it comes from, and how healthy it is for us, and perhaps encourage us to have a more generalized, varied, and more nutritious dietary range... :)

Do you prefer grasshopper to ants? How about some fried lice? Could this be the future of dinnertime conversation??!!

Insects produce much smaller quantities of greenhouse gases per kilogram of meat than cattle and pigs. This is the conclusion of scientists at Wageningen University who have joined forces with government and industry to investigate whether the rearing of insects could contribute to more sustainable protein production. Insect meat could therefore form an alternative to more conventional types of meat in the future.

Cattle farming worldwide is a major producer of greenhouse gases. For the assessment of the sustainability of insect meat, the researchers at Wageningen University quantified the production of greenhouse gases of several edible insect species. The results of the study were published in the renowned online journal PLoS ONE on 29 December.

The research team has for the first time quantified the greenhouse gases produced per kilogram of insect product. The gases concerned were methane (CH4) and nitrous oxide (N2O). The results demonstrate that insects produce much smaller quantities of greenhouse gases than conventional livestock such as cattle and pigs. For example, a pig produces between ten and a hundred times as much greenhouse gases per kilogram compared with mealworms.

Emissions of ammonia (which causes the acidification and eutrophication of groundwater) also appear to be significantly lower. A pig produces between eight and twelve times as much ammonia per kilogram of growth compared to crickets, and up to fifty times more than locusts. An additional advantage of insects over mammals is that they convert their food into meat quicker.


The study indicates that proteins originating from insects, in principle, form an environmentally-friendly alternative to proteins from meat originating from conventional livestock. Further research is required to ascertain whether the production of a kilogram of insect protein is also more environmentally friendly than conventional animal protein when the entire production chain is taken into account.
