Dr. Noor Liyana Yusof from Lund University has found a way to help the youngest Swedes make sure they eat their spinach — safely.

Spinach, one of the most popular greens for healthy diets, isn’t so safe for infants and small children because the levels of nitrates found in the leafy greens are too high for small bodies to process.

Dr. Yusof's simple method of "placing the leaves in a sugar solution and then vacuum-treating them forces the sugar molecules to get into the leaves, stimulating their metabolism, so that nitrates are reduced” up to 70 percent, so it remains safe for all to enjoy.
