Eat Well, Sleep Well

We stumbled upon this great article, Cooking Up A Sleep-Friendly Diet, by Dr. Michael J. Breus on the Huffington Post Healthy Living section.  These suggestions just might help you get a better night’s sleep!

Foods full of vitamins and minerals are the basic components of a healthy diet, promoting healthy cell function, helping regulate weight, and providing the energy we need to get through our busy days. Many of the foods that are most healthful to our bodies and our waistlines are also the foods that can help us sleep better. Here are some suggestions for creating a sleep-friendly diet.

Reach for These Healthy, Mineral-Rich Foods:

Magnesium is a mineral that functions to relax nerves and muscles and also promotes healthy circulation. Deficiencies of magnesium have been associated with several sleep disorders, including insomnia and restless leg syndrome. Foods high in magnesium are some of the most sleep-friendly foods around.

Bananas are a great source of magnesium. So are many other nutrient-rich, waist-friendly foods, including:

    • Fruits: in addition to bananas, avocados, berries and melons
    • Leafy greens: spinach and Swiss chard
    • Nuts and seeds: including cashews, almonds, pumpkin and sunflower seeds, and nut or seed butters
    • Beans: black beans, tofu, soybeans
    • Whole grains: brown rice, millet, wheat and oat bran

Potassium is another key mineral in the body that helps to relax muscles and nerves, as well as to promote healthy circulation and digestion. Research has shown a possible genetic link between potassium and slow-wave sleep: a study at the University of Wisconsin found that a gene in fruit flies that is responsible for regulating the flow of potassium is also the gene that allows for slow-wave sleep. Slow-wave sleep, also known as delta sleep, is the deepest phase of our sleep cycle, the time when we get our most restorative sleep.

Bananas win again, as a great source of potassium as well as magnesium. Other healthy foods that contain high levels of potassium are:

    • Vegetables: leafy greens, mushrooms, tomatoes and cauliflower
    • Beans: including lima, soybeans, lentils, pinto and kidney beans
    • Fish: salmon, cod, and flounder
    • Citrus: especially in juice form, in sources like orange juice

Calcium is a mineral that plays a direct role in the production of melatonin, the “sleep hormone” that helps to maintain the body’s 24-hour sleep-wake cycle. Melatonin levels rise naturally during the night, helping promote sleep, and are suppressed during the day, allowing us to be alert and wakeful. Calcium, like magnesium and potassium, is also a natural relaxant in the body.

Dairy products are rich in calcium, and can be a good choice for a sleep-friendly evening snack. That glass of milk your mom had you drink before bed? Turns out, mom was right. There are other non-dairy foods that are also packed with calcium. If you’re not fan of yogurt, milk or cheese, try these options for bringing more sleep-promoting calcium into your diet:

  • Dark leafy greens: turnip greens, collards, spinach, mustard greens, kale
  • Nuts and seeds: Brazil nuts, almonds, sesame seeds
  • Soy: tofu, soymilk

On the subject of melatonin: There are very few foods that contain melatonin and that can therefore provide the body with a natural source of this important hormone. Melatonin supplements are readily available, but don’t work the same way in the body that a naturally produced or derived melatonin will. One of the very few sources of melatonin in foods?

Cherries. One study found that adults who drank tart cherry juice in the morning and the evening for two weeks reported significant reduction in insomnia. Fresh and dried cherries, as well as cherry juice, are a potent natural source of melatonin.
Take Your Vitamins

It’s a great plan to try to get as many of your nutrients from whole foods as possible — structuring your diet this way will naturally lead you to eating well. But vitamin and mineral supplements can play an important role in helping maintain your health and your sleep. These are some of the best supplements for sleep:

Vitamin B. There are several supplements on the B spectrum that can boost your sleep. Vitamin B3 (also known as niacin) has been shown to promote REM sleep. Vitamin B6 helps the body to produce serotonin, which is known as the “calming hormone.”

Calcium and Magnesium. In addition to creating a diet of calcium- and magnesium-rich foods, these minerals can also be effective in supplement form. Taking these together in a 2:1 ratio (calcium: magnesium) can help the body prepare for sleep, and also guard against the deficiencies of these important minerals that have been linked to sleep disorders.

Vitamin D. This supplement has made plenty of news in recent years, with much discussion of how deficiencies in vitamin D can lead to depression, weight problems and difficulties with sleep. This recent study of veterans suffering from both chronic pain and vitamin D deficiency found that vitamin D supplements led to both reduction in pain, and improvement to sleep and to the veterans’ sense of wellbeing.

There is no single magic bullet that can eliminate sleep problems — that is to say, switching to a bananas-only diet not only isn’t practical, it isn’t going to make your sleep troubles disappear. Creating and maintaining a strong sleep routine is about more than just what you eat — but eating well can surely help.
