Supermarket Lights Boost Vegetable Nutrition Value

The nutritional value of vegetables kept under fluorescent lights in supermarkets increases up to 100% as opposed to those that aren’t, according to new study.

US Department of Agriculture research plant physiologist Gene Lester said continuous fluorescent lighting and a chilled temperature saw the concentration of some vitamins in spinach grow by 15-20% within three days.

“After nine days, it was found that folate (vitamin B) and vitamin K had risen to 100%,” Lester said.

Continuous light exposure allows plants to maintain photosynthesis which in turn produces nutrients.
