Supermarket Lights and Vegetables
Don’t fear that sturdy lighting in supermarkets is unhealthy for contemporary greens. In reality, it might really improve their nutrient ranges.
In a United States Division of Agriculture (USDA) examine, spinach was saved in clear plastic containers underneath fluorescent lights for 3 to 9 days, which induced the leaves to synthesize extra vitamin C, Okay, E and folate, in addition to carotenoids corresponding to lutein. After 9 days, as an illustration, ranges of folate and vitamin Okay rose by as a lot as 100 %. In distinction, vitamins in spinach that had been saved at midnight declined or had been unchanged.
These findings must also apply to many different contemporary leafy greens, so long as they’re saved cool and moist.
