Diet and fat and flashes! Oh my!

A lot of you have written to me back channel to see if there is any evidence that diet affects menopausal symptoms. Up until now, I have run across many articles but little evidence on the topic. Hence, I was heartened to read about the positive effect of dietary changes and weight loss on hot flashes and night sweats in the online edition of Menopause.

The original intent of this study of over 17,000 women was to assess how a low-fat diet might benefit heart disease, breast and colorectal cancer and fracture risk among postmenopausal women. Nearly half of the women were asked to reduce their fat intake to only 20% of total energy and increase daily fruits and veggies intake to at least 5 servings daily, and whole grains, to 6 servings daily. Over the course of 5 years, they also received regular, intensive behavioral training conducted by a nutritionists and registered dietitians. The other half of the women only  received a copy of Dietary Guidelines for Americans and other health-related materials. All were between the ages of 50 and 79.

Although weight loss was not a study goal, per se, on average women who agreed to changes in their diet lost an average of 4 pounds in the first year. And these women were able to reduce night sweats and hot flashes. What’s more? Women who lost more than 10% of their overall weight were significantly likely to eliminate their symptoms entirely (note that only a small proportion of women — 1% — reported having severe night sweats or hot flashes and symptoms were mostly mild to moderate in intensity). But, the findings get even more granular. The researchers write that when they did an additional analysis that women who lost the most weight (22 lbs) had more than twice the odds of eliminating moderate or severe vasomotor symptoms compared with women who maintained their weight.

Although the reasons are unclear, weight loss may reduce the amount of adipose tissue -the tissue that stores fat — and by default, reduce its insulation-type, thereby boosting the body’s ability to attack excessive body heat. Regardless, there are many reasons to maintain weight as we age. If this is an additional benefit, I say bring on the fruits and vegs!
