The Milk Myth
A recent study claims that young adults are not drinking enough milk -- that is, if you read what the media reports. But if you really read the study according to the lead author Nicole Larson, it's calcium they're lacking. The words "milk" and "calcium" are often used interchangeably in the popular press. But while milk is a calcium source, no standard other than that of the National Dairy Council considers it the best calcium source.
The suggestion that you need to drink three glasses of the secretion of a cow's mammary glands in order to be healthy is a bit outrageous and doesn't fit the human evolutionary profile. In fact, most humans around the world cannot easily digest cow milk.
Yogurt has more calcium than milk and is easier to digest. Collards and other greens also have about as much or more calcium than milk by the cup. Greens, unlike milk, have the added benefit of vitamin K, also necessary for strong bones. Sesame is also very high in calcium.
When you measure calcium by cup of food product, milk is high on the list. When you view it by calorie, though, milk is at the bottom. A hundred calories of turnip greens have over three times as much calcium as 100 calories of whole milk.

Food of the Week . . . Collard Greens
Did you know that one cup of cooked collard greens will provide you with almost as much calcium as a cup of milk? Milk products are often considered the best source of calcium, so you may be surprised to find that while one cup of 2% milk provides 29% of the daily value (297 mg) for calcium, one cup of cooked collard greens contains almost as much: 23% of the daily value (226 mg)! And the collard greens have half the calories of the milk (50 calories compared to 121) with virtually no fat. Calcium is known primarily for its role in maintaining the strength and density of bones, but recent studies have shown that it is also important in helping to protect colon cells from cancer-causing chemicals, preventing migraine headaches, and reducing PMS symptoms during the second half of the menstrual cycle. Since the body tightly controls the amount of calcium in the blood so that sufficient calcium is always available, when dietary intake it too low, calcium is pulled out of the bones to maintain normal blood concentrations. This is why low dietary calcium can, over many years, lead to osteoporosis. So next time you are wondering how to boost your calcium intake, don't just think milk, think collard greens!Read More ...
