Fish
When your diet is deficient in omega-3s—a very common nutrient in
fish—your pineal gland—a gland in your brain that helps regulate your
nervous system—is thrown off, leading to alterations in the production
of melatonin, your sleep hormone. People with an omega-3 deficit don't
sleep during their usual rest periods, which can lead to things like
unhealthy late-night eating.
Fish is also rich in protein, which previous research has shown can
satiate your appetite. You even burn more calories digesting protein
than you do when you eat fats or carbs. Plus, eating more omega-3s can
boost heart health and lower your risk of dementia.
Nuts
These legumes are a great source of mood-boosting magnesium. And
eating more of it can help people who have sleep troubles doze
peacefully through the night, according to a 2010 study published in the
journal Magnesium Research. One group of the 100 tossers-and-turners
over age 51 was given 320 milligrams of magnesium a day, while the other
group was given a placebo. After seven weeks, those taking the
magnesium were sleeping better—which research shows can lead to less
overeating and weight gain. As a bonus, the women had lower levels of
dangerous inflammation, a rogue reaction by the immune system that is
implicated in heart disease, cancer, diabetes, and Alzheimer’s disease.
Milk
It turns out that milk may really do a body good when it comes to
belly fat. A 2010 study by researchers at the University of Alabama at
Birmingham found that among a group of more than 100 premenopausal
women, fat was significantly reduced in those who consumed the most
calcium-rich foods. In fact, for every 100 milligrams of calcium they
consumed per day (that's half cup of soft-serve frozen yogurt), they
lost an inch of intra-abdominal fat—the really bad stuff tucked in and
around your internal organs that has been linked to higher rates of
heart disease and cancer.
Calcium can also help you sleep if you tend to be awakened by
muscle soreness or cramps—the mineral, along with calcium, helps relax
muscle nerves and fibers.
Cherries
Around bedtime, munch on a few tart Montmorency cherries. These
cherries are one of a number of plant-based sources of melatonin, the
sleep hormone. While there's no evidence that they'll help you nod off,
studies have found that foods like these (such as bananas) can raise
melatonin levels in the body. Not only does melatonin help you sleep,
but it's a powerful antioxidant, which can also promote weight loss.
