As critical pollinators, bees keep our agricultural systems going—but human-caused changes to the planet heavily impact their foraging options. To help protect our food security, we need more information about bees' own dietary requirements. Scientists writing in Frontiers in Sustainable Food Systems have studied the nutritional value of 57 types of pollen and found that bees need to forage from a variety of plants to balance their diet between fatty acids and essential amino acids.
