Almost everyone suffers from trouble sleeping at one time or another. Insomnia — defined as trouble falling asleep or staying asleep — isn't a single disorder itself, but rather a general symptom, like fever or pain.

Because insomnia is so common, you can walk into any drugstore and find a bewildering variety of over-the-counter sleep products. And people are buying them. One small survey of people ages 60 and over found that more than a quarter had taken nonprescription sleeping aids in the preceding year — and that one in 12 did so daily.

Q. I've been drinking Fresca since I was in college. Lately I've been reading that diet drinks may cause weight gain and have other bad effects. Is that true?

A. There is some controversy about whether drinking diet soda helps or hurts in maintaining or achieving a healthy weight. Some studies show that people who consume artificially sweetened drinks take in fewer calories and are better able to control their weight. However, other studies show the opposite—that consuming diet drinks may result in weight gain as well as type 2 diabetes.

Many of my patients, colleagues, friends, and even neighbors have asked me about the new drug flibanserin (Addyi), which the FDA recently approved for treatment of low sexual desire in women. Flibanserin has generated more questions, comments, and media inquiries for me than I've ever experienced in my 20-year career as an obstetrician/gynecologist. While there are several medications that improve sexual function in men (including Viagra, the most famous one), flibanserin is the first to be approved for that purpose in women. Here are what I consider the relevant facts about flibanserin, and what I say to my patients.

Beer, wine, and spirits are foods as well as intoxicants that have different effects in women than in men.

In the first episode of the sitcom "Grace and Frankie," the title characters, played by Jane Fonda and Lily Tomlin, are ordering drinks before dinner. When carb-conscious Fonda sends the breadbasket away and asks for a very dry vodka martini, Tomlin reminds her that vodka is made from potatoes. Fonda responds, "Alcohol has its own rules."

These potent medications are for hard-to-manage cases of high cholesterol—not replacements for the tried-and-true statins.

Here's how to enhance the foods you already like with heart-healthy plant sources.

According to a recent national food survey by the CDC, 87% of American adults do not eat the minimum daily recommended portions of fruit (1.5 to 2 cups), and 91% are not getting the recommended amount of vegetables (2 to 3 cups a day). The reasons for this unhealthy trend vary. One important factor is that food preferences, including an aversion to fruits and vegetables, form early in life and can be hard to change. "People say, 'I don't like salad' and 'I don't like spinach,' and that's that," says Stacey Nelson, a registered dietitian and manager of clinical nutrition at Harvard-affiliated Massachusetts General Hospital.

Research we're watching

Want to nudge down your cholesterol level? Try a bowl of oatmeal for breakfast. New research adds to earlier evidence that among the whole grains, oats are the most effective choice when it comes to lowering cholesterol.

The findings were gleaned from 24 studies that looked at blood lipids (cholesterol and triglycerides) in people who ate diets featuring whole-grain foods versus non-whole-grain control diets. Compared with the control diets, whole-grain diets lowered total cholesterol levels by an average of 4.6 points. Diets featuring oats proved to be slightly superior, dropping cholesterol levels by 6.5 points, on average. An added bonus: whole-grain diets don't appear to lower beneficial HDL cholesterol. The report appeared in the September 2015 American Journal of Clinical Nutrition.
