title=”No 10: Iceberg lettuce”
content=”It’s no surprise that iceberg lettuce is among the least nutritious greens you could put in a salad. In fact, Chick-fil-A has even banned the veggie from its stores, allegedly because of its low nutritional content. Iceberg lettuce only has about 7% of your daily vitamin A per cup, as well as only 3% of daily vitamin C, among the lowest on the list.

title=”No. 8: Kale”
content=”Trendy for a reason, kale kills it in vitamin content, especially A, C, and K. Vitamin K is especially important in helping blood clot. But kale has one tiny downside: it’s a tad higher in calories than other greens (though it’s still very low!) which means that technically it has a lower nutrient density, the amount of nutrients packed into each bite.
