"To make wholesome, nutritious, tasty and safe foods, it is essential that food scientists pool their knowledge and resources together in a multidisciplinary approach. With approximately 15,000 scientists, employed by nearly 1,500 food related companies, the Netherlands is a center of the food formulating world. The Dutch government puts a high value on developing nutritious foods, as the country recognizes the impact that a poor diet has on health, and, as a consequence, public health care." .
"An estimate is that 70% of all the vegetables grown in the United States have Dutch genetics."
Excuse the nationalism... research into breeding and growing food is obviously a big thing here, and while I cannot derive any expertise from that myself, I do read a lot of research from said scientists and our agri uni and they never focus on yield alone. When it comes to yield the goal is always improving the yield without sacrificing quality in terms of nutrition value, looks, and taste. They measure kg/m2 (yield) but also things like sugar vitamin contents, and test for texture and taste rigorously. Whether it comes to using synth nutes or LED or alternative light schedules for example, they care about every aspect of the product, not just weight and looks.
