By increasing fruit and vegetable intake to at least the five recommended portions a day, a better balance of vitamins and minerals can be achieved. This is relevant for PMS as many studies over the years have shown deficits in micronutrients in women suffering from PMS, particularly vitamin B6, Vitamin D, calcium, magnesium and manganese (Penland and Johnson, 1993, p1471; Bertone-Johnson et al, 2005, p1246; Shamberger RJ, 2003, p123; Thys-Jacob, 2005, p220; Facchinetti et al, 1991, p177: Moyad, 2003, p 69).
The lack of green vegetables in the diet in particular is one of the first issues that need to be addressed. Green vegetables are a rich source of calcium, magnesium and vitamin B6 and the patient needs to be advised that their introduction should be immediate. Calcium deficiency in particular is the most cited in the medical literature as being reliably found to be a player in PMS.
