Treatment
Making dietary adjustments starting about 14 days before a period may help some women with certain mild menstrual disorders, such as cramping. The general guidelines for a healthy diet apply to everyone; they include eating plenty of whole grains, fresh fruits and vegetables, and avoiding saturated fats and commercial junk foods.
Effects of Dietary Fats. A 2000 study reported that women who followed a low-fat vegetarian diet for two menstrual cycles experienced less pain and bloating and a shorter duration of premenstrual symptoms than those who ate meat. Women who are losing too much blood, however, may need meat to help maintain iron levels. Choosing more fish and eggs may be a helpful alternative.
More than one study has reported less menstrual pain with a higher intake of omega 3 fatty acids (fat compounds found in oily fish, such as salmon and tuna). In one study, supplements of fish oil also appeared to reduce heavy bleeding in adolescent girls.
Salt Restriction. Limiting salt may help bloating. One study found that restricting salt does not alleviate bloating or other symptoms, but salt reduction in the study was modest and may have been too small to effect improvement.
Reducing Caffeine, Sugar, and Alcohol. Reducing caffeine, sugar, and alcohol intake may be beneficial. The effects of alcohol are mixed. One study found that women who drank less wine had less menstrual pain than those who drank more wine. Another reported that regular consumption of alcohol lowered the risk for developing cramps, but it actually increased the length of cramping time in certain women. Alcohol is certainly not recommended in any case for relieving menstrual disorders.
Maintaining Healthy Iron Stores and Preventing Anemia
Forms of Iron. Women who have heavy menstrual bleeding can sometimes become anemic. Eating iron-rich foods can help prevent anemia. Iron found in foods is either in the form of heme or non-heme iron. Heme iron is the better absorbed than non-heme iron.
- Foods containing heme iron are the best for increasing or maintaining healthy iron levels. Such foods include (in order of iron-richness) clams, oysters, organ meats, beef, pork, poultry, and fish.
- Non-heme iron is less well absorbed. About 60% of iron in meat in non-heme (although meat itself helps absorb non-heme iron). Eggs, dairy products, and iron-containing vegetables only have the non-heme form. Such vegetable products include dried beans and peas, iron-fortified cereals, bread, and pasta products, dark green leafy vegetables (chard, spinach, mustard greens, kale), dried fruits, nuts, and seeds.
