One cup of chopped swiss chard has a mere 35 calories and provides more than 300% of the daily value for vitamin K.

Chard is a hardy crop to grow, available year-round and is unique in that it does well in both cool and hot temperatures. Because swiss chard’s bulky leaves are highly perishable, they are more often sourced by grocers through local farmers and found in farmers markets. 

Surprisingly, swiss chard is not native to Switzerland, rather it was studied by a Swiss botanist who classified the plant in the 1800s after he discovered it in Italy.
