Popeye Was Right

Popeye was right: spinach does make you stronger--as do beets and chard. These foods are high in nitrates, which have been associated with stronger muscles. A recent study published in the Journal of Physiology found that mice given the mouse equivalent of a 200-300 gram serving of spinach a day had considerably stronger muscles than mice not fed spinach. The mice with the higher nitrate levels also had higher levels of two particular proteins, CASQ1 and DHPR, that are crucial in calcium balance and ultimately muscle contraction.  The researchers now want to apply what they've learned in mice and apply it to people. Spinach, beet, and chard have so many health benefits, that it wouldn't hurt to include them in your diet one way or another.
