Calcium: Collard Greens Have More Than Milk

According to this article from the Harvard School of Public Health, one cup of collard greens contains 357 milligrams of calcium, but a cup of milk has 306. Collard greens also are one of the leafy greens with calcium that is more absorbable. (Some greens like spinach contain oxalic acid which interferes with absorption of calcium).

In addition to calcium, Collard greens contain Vitamin K which plays a role with calcium in keeping bones healthy and strong. Three proteins in bone depend upon Vitamin K to function. Collard greens are a member of the cabbage family.

The leafy vegetable has been a regular part of American cooking in the South, aka ‘soul’ food for decades. (They were also popular with the ancient Greeks and Romans). In the South, they are often cooked with black eyed peas. A Collard Greens Festival has been held for several years in East Palo Alto celebrating Southern African-American culture.

In Portugal, soup is made with the greens, potatoes, onions, garlic, salt, savoy cabbage, and pork sausage, although tofu could be substituted for the pork.

Kevin Gianni has a video for Vegetable Wraps with Collard Greens and Tahini Sauce.
Chef Keith Snow provides some video tips for washing and cooking them Southern Style.

The vegetable is usually planted in the early spring. In the South it can also be planted in midsummer and harvested in fall or early winter.

My Portuguese mother-in-law makes the most delicious "caldo verde" (collard green soup), with no meat at all. Most soups in the poorer Portuguese country-side is made without any meat or meat substitutes. My mother-in-law simply cooks potatoes and onion (and garlic, but not always) in water with some salt, mashes the potatoes, onion and garlic when done, adds the very finely cut-up collard green and olive oil (never ever forget to put olive oil in Portuguese soups!), lets it boil some more until the collard green is done. This makes a very tasty and healthy soup. The translation of "caldo verde" is: green broth.

@Thomas T..I agree with care needed with the mambers of the Nightshade family, but as for the Greeks being crippled with arthritis from Moussaka, this is a dish made with HUGE amounts of CREAM/MILK..and as a human calcium source, Cows milk is MOLECULARILY is so large as to be un-absorbable by the human body, so it just gets shoved "out of the way" ..and the only place this can be done in the human body, is the spaces in the joints..thus resulting in arthritis...also, since the body cannot use the calcium from dairy, it needs to get it somewhere, so if another source is not given..(Greens, fruits, etc) will naturally "ROB IT" from wherever it can find it...that being the bones..actually CAUSING osteoperosis!!! For "FIT FOR LIFE" by the Drs Diamond...I read this and a couple others, stopped MY dairy intake, and within 2 months, ALL my arthritis was gone...told my brother, and his went away too!!! All I know for sure, is it worked for us!!!
