Though spinach does give us iron, our bodies can only use about half of what is present within the leaves, because the iron is tightly bound to oxalic acid, a substance which makes it hard for our bodies to absorb.
Although we can get more iron from a juicy steak or a can of sardines, it doesn’t mean we should toss Spinach onto the compost heap. Our green leafy friend is actually packed full to the brim with the yellow pigment lutein. You may not be able to see it due to the presence of green chlorophyll but it is there nonetheless and it is great for protecting our eyes from sun damage that over the years damages a spot at the back of the eye called macular lutea.
Spinach is also good for B vitamin folate, which lowers the artery clogging homocysteine as well as giving us a good dose of vitamin C.
If you are worried your supermarket bought spinach leaves aren’t giving you all the benefits listed above and you’d be better served if you popped down the market then wrong again. A recent study has actually found that the fluorescent lighting at supermarkets actually boosts its certain levels of nutrients.
