24 Jul 2018 --- Insects have come into the spotlight over the past years as being a good source of healthy protein and several other nutrients, as well as more environmentally friendly in their production than many other animal-derived proteins. The one gallon of water it takes to produce one pound of insect protein pales in comparison to the almost two thousand gallons of water poured into every pound of beef destined for human consumption. Scientists at Wageningen University & Research (WUR) have now uncovered another reason to consume insects by proving that certain insects can be a rich source of vitamin D following exposure to ultraviolet radiation. The researchers have presented their results in the journal Scientific Reports.
