8. Add more iron
While the macrobiotic diet can be very good for your health, it's does have a few nutritional pitfalls. The total lack of meat means that it's difficult to get adequate iron. While wholegrains and some vegetables and beans contain some iron, it is less bioavailable (i.e not as easily absorbed) and usually far less than meat. For example: 100 grams of red meat equates to roughtly 10 per cent of your daily iron needs, whereas 100 grams of brown rice would only equat to three per cent. According to the Australian and New Zealand nutrient reference values, women between the age of 18 and 50 need around 18 milligrams of iron each day. (Factoid: that's 10 milligrams more than men.) Vitamin A, calcium, vitamin B12 and zinc might also be deficient in a macrobiotic diet.
