The Micronutrient-Rich Royal Jelly of Bees

The Micronutrient-Rich Royal Jelly of Bees

The micronutrient content of bee feed decisively determines whether larvae become queens or only worker bees. Every bee larvae carries the same genetic predisposition. Their potential to develop into a queen is regulated by the nurse bees which change the quality of the diet three days after hatching. Mostly fed with pollen and nectar, most bees become workers. Only a few, privileged larvae receive the royal jelly, a high-quality micronutrient-rich secretion. In addition to sugar, water and protein, it contains fatty acids, thiamine (B1), riboflavin (B2), niacin and folic acid.

Australian and German scientists have found an answer to how such a major difference in the function and shape of bees can result from the same genome (1). Due to the changed diet, chemical changes (methylation) take place on the surface of the DNA. Genetic analyzes of the research group suggest that methylation affects the splicing, meaning the assembly of the “genetic blueprint” into a finished protein and thus cause epigenetic changes. Since this connection between diet and genetic material can also be demonstrated in humans, this can be a vivid motive for engaging in micronutrient deficiency in the first 1,000 days of life (2).
