Your question: Many women experience a strong craving for sweets(chocolate, candy, etc) immediately before and during menstruation. Moreless, is this due to a higher need for calcium during this time?
Answer: Yes, and also for the need of many of the other needed Alkaline Minerals !
What actually may take place when one eats the Sweets, may be that they produce more Acids, which may Temporarily help Release more Electro-magnetic Energy from what Alkaline Minerals one may be eating, or Remove from the Bone structure for this purpose ?
Thus it may be best to learn to supply the needed Calcium and other Alkaline Minerals to help Alkalize the body, thus preventing this Desire for Sweets ?
Smile Tis your choice.
