The PMS-Free Diet?
What you eat may affect PMS symptoms
By Elaine Magee, MPH, RD
A whole lot of you will answer "yes." According to some estimates, about two-thirds of women report regular premenstrual discomfort, with about one-third seeking help from a health care provider. Up to about 8% of women experience severe impairment (called premenstrual dysphoric disorder).
What kinds of symptoms are included in the catchphrase "PMS"? A cornucopia of complaints, including breast swelling and tenderness, bloating or water retention, headaches, irritability and moodiness, depression, food cravings, and more.
These pesky and sometimes debilitating PMS symptoms occur between ovulation and the start of your period. Here's the bad news for all you 20-somethings out there: PMS becomes increasingly common in women as they move through their 30s. And symptoms can get worse over time.
Now here's some better news for all PMS sufferers. Did you know that what you eat can affect your PMS symptoms? And sometimes, it isn't what you add to your diet but what you take away that helps. Read on for suggestions on foods to choose and foods to lose.
The Calcium Connection
Probably the strongest potential PMS helper is calcium. Several studies have suggested that PMS patients tend to have an altered calcium balance and are also at increased risk of osteoporosis. Other studies have linked adequate intakes of milk and calcium with reduced PMS symptoms.
Further, a Turkish study on PMS symptoms in adolescent girls found that higher milk consumption was associated with reduced bloating, cramps, and food cravings.
How much calcium is enough? Some suggest that we should shoot for 1,200 milligrams a day.
This is very doable with foods alone, as long as you like and tolerate dairy products. Here are some of the top calcium-rich foods:
And if you don't like dairy? Supplements may help, too.
In a Columbia University study, women with moderate to severe PMS who took two Tums E-X tablets twice a day (for a total of 1,200 milligrams of elemental calcium), showed a 48% reduction in PMS symptoms.
About 11% of women have moderate to severe breast pain and soreness, according to a recent study.
"Some suggest that a high-fat diet may have something to do with
Another recent study suggests that flaxseed -- already famed for its healthy omega-3 fatty acids -- may also help women with breast pain.
Researchers at the University of Toronto tested flaxseed's effects on premenopausal women with breast pain. For a six month period, one group of women ate a muffin containing 25 grams of flaxseed every day, while another group ate a muffin without flaxseed.
The flaxseed-eating women reported much less breast pain than the other group. This may be because the lignans in flaxseed are plant estrogens that compete with human estrogen.
A B-6 Bonus?
The reviews are mixed, but it's possible that daily vitamin B-6 helps improve PMS-related depression as well as physical symptoms.
Although some sources suggest 50-100 milligrams per day of B-6, the Daily Value for women aged 19-50 is a mere 1.3 milligrams per day. That's a huge gap, and one that can't be realistically filled with food sources of B-6. You'll see what I mean when I list the top B-6-containing foods:
Even on a "good" day (if you ate 3.5 ounces of light chicken or fish a day, 2 cups of colorful fruit, and 2 1/2 cups of colorful vegetables), you'd take in about 2 milligrams of B-6 from food.
Keep in mind, though, that very large doses of B-6 supplements can be toxic over time -- something that can't happen with food sources of B-6. The 1998 Recommended Dietary Allowance/Dietary Reference Intakes committee set the upper limit for B-6 at 100 milligrams per day for people aged 19 and older.
