Keep coming back for more. This page gets updated quite frequently. It's too bad teen-aged girls and women have to resort to chronic dieting, but in a culture bursting with fattening food marketing and consumption it must be very hard for them to try and maintain a healthy weight. Many get much of their calcium from dairy products with a significant amount of saturated fat. This fat often contributes to the development of the number one killer heart disease, the number 3 killer stroke and is suspected of contributing to the development of some cancers.
Calcium does exist in plant sources but is also accompanied by oxalates which inhibit absorption.
I have read that Spinach is high in oxalates, but it is my understanding that most other greens are pretty low in this substance to the point where it is not a significant concern. And most plant sources are loaded with fiber and nutrients that most Americans already get too little of. I'm not an expert on nutrition, but the points I raise are important to me as one who is concerned about his bone health and overall health. Input is appreciated. They don't diet to be healthy, they diet in response to social and media pressures.
