Ailments and Situations - Premenstrual Syndrome or PMS - Causes - Type C

Type C (Carbohydrates, Cravings)

Sixty percent of women have increased cravings for refined carbohydrates, particularly sugar, chocolate, alcohol, white bread, white rice and noodles prior to menses. Researches believe this is due to some women having an increased insulin sensitivity the week before menses. Meaning that more sugar is transported out of the blood and into cells. This leaves less circulating glucose for the use by the brain (as glucose is the only fuel source that can be used by the brain) and a subsequent increased craving. This craving intensifies under stress and with nutrient deficiencies such as magnesium, B vitamins and chromium.

It is interesting to note the significant number of women who crave chocolate just before their menses. Chocolate is a rich source of magnesium and phenylethylamine (a potent anti-depressant) and hence such a craving may be a sign that the body is seeking out the nutrients that it is deficient in. However, it is important to remember that chocolate also contains a number of ingredients that worsen PMS.
