Dark leafy greens (calcium leafy greens) and broccoli are widely recognised for having a high calcium content. Although they can serve as a substitute for dairy products when it comes to calcium intake, these vegetables are difficult for your body to absorb. if your main sources of calcium are broccoli and leafy greens.
Role of the calcium:
The mineral calcium predominates in your body. A little portion of the calcium you consume is necessary for other processes, but its main purpose is to maintain bone growth and structure. Calcium is essential for keeping the heart healthy and facilitating neuronal communication.
A healthy adult needs around 1,000 mg. of calcium per day. While , women over 50 need more than 1,200 mg., but males don’t require this amount until they are over 70.
More than 20 milligrammes of calcium may be found in a 1/2 cup portion of cooked broccoli. One cup of cooked spinach or another leafy green vegetable has roughly 70-75 milligrammes. Around 110 milligrammes of calcium are present in a 1/2 cup serving of sautéed spinach(calcium leafy greens).
Milk v/s green leafy vegetables calcium(calcium leafy greens):
Dark leafy greens and broccoli both provide calcium that is comparable to that in milk and other dairy products. Oxalic acid, which is included in dark green vegetables, binds to calcium and prevents your body from absorbing it. If you drink a glass of milk with your meal, oxalic acid can also bind to the calcium in the milk, according to the Office of Dietary Supplements. Save your glass of milk until later in the evening if your supper includes a side of broccoli or other dark green vegetables. This will ensure that the oxalic acid in the vegetables is properly digested and does not interfere with the body’s ability to absorb calcium from the milk.
