Food and Diet
Diet is especially important when treating sleep disorders, and it is essential to rule out food intolerances as a cause. In one study of infants, sleeplessness was eliminated by removing cow's milk from the diet and then reproduced by its reintroduction.

Certain types of food promote sleep while others inhibit it.

Foods to Eat

Chlorophyll-rich foods, such as leafy, green. vegetables, steamed or boiled.

Microalgae, such as chlorella and spirulina.

Oyster shell can be purchased in health food stores and taken as a nutritional supplement.

Whole grains: Whole wheat, brown rice, and oats have a calming and soothing effect on the nervous system and the mind. Carbohydrates also boost serotonin, which promotes better sleep.

Mushrooms (all types)

Fruit, especially mulberries and lemons, which calm the mind.

Seeds: jujube seeds are used to calm the spirit and support the heart. Chia seeds also have a sedative effect.



Foods such as bread, bagels, and crackers that are high in complex carbohydrates have a mild sleep-enhancing effect because they increase serotonin, a brain neurotransmitter that promotes sleep.

A glass of warm milk with honey is one of the oldest and best remedies for insomnia. Milk contains tryptophan which, when converted to seratonin in the body, induces sleep and prevents waking.

Lettuce has a long-standing reputation for promoting healthy sleep. This is due to an opium-related substance combined with traces of the anticramping agent hyoscyarnin present in lettuce. Lettuce should be an integral part of your evening diet if you are suffering from sleep disorders. The meal should also include legumes, peanuts, nutritional yeast, fish or poultry. These foods contain vitamin B3 (niacin). Niacin is involved in seratonin synthesis and promotes healthy sleep. Mixed with a little lemon juice for flavor, lettuce juice is an effective sleep-inducing drink highly preferable to the synthetic chemical agents in sleeping pills.

Foods to Avoid



Spicy foods



Stimulant drugs


Refined carbohydrates (They drain the B vitamins.)



Non-organic foods containing pesticides.

Canned foods or any source of toxicity or heavy metals.

Sugar and foods high in sugar and refined carbohydrates. These raise blood-sugar levels and can cause a burst of energy that disturbs sleep.

Foods that are likely to cause gas, heartburn, or indigestion, such as fatty or spicy foods, garlic-flavored foods, beans, cucumbers, and peanuts.

Foods such as meat that are high in protein can inhibit sleep by blocking the synthesis of serotonin, making us feel more alert.

Monosodium glutamate (MSG), often found in Chinese food. This causes a stimulant reaction in some people.

Avoid cigarettes and tobacco. While smoking may seem to have a calming effect, nicotine is actually a neurostimulant and can cause sleep problems.

Alcohol and caffeine are two beverages/food that you must avoid for a healthy sleep. Avoid caffeine in all forms (tea, coffee, cola, chocolate). See Also: Caffeine Content of Common Beverages for a table of caffeine in common beverages.

The sensitivity to the stimulant effects of caffeine varies greatly from one person to the next. This is largely a reflection of how quickly the body can eliminate caffeine. Even small amounts of caffeine such as those found in decaffeinated coffee or chocolate, may be enough to cause insomnia in some people.
Alcohol produces a number of sleep-impairing effects. In addition to causing the release of adrenaline, alcohol impairs the transport of tryptophan into the brain, and, because the brain is dependent upon tryptophan as the source for serotonin (an important neurotransmitter that initiates sleep), alcohol disrupts serotonin levels.

Avoid too many ingredients in a meal and too much food late at night.


If you want to fall asleep more easily, eat a high-carbohydrate snack and avoid high-protein foods in the hour or two before bed time.

In the evening, eat turkey, bananas, figs, dates, yogurt, milk, tuna, and whole grain crackers or nut butter. These foods are high in tryptophan, which promotes sleep. Eating a grapefruit half at bedtime also helps.

Avoid bacon, cheese, chocolate, eggplant, ham, potatoes, sauerkraut, sugar, sausage, spinach, tomatoes, and wine close to bedtime. These foods contain tyramine, which increases the release of norepinephrine, a brain stimulant.

Our digestive system slows at night. So, it is harder to digest late meals. Avoid heavy meals before bedtime.

How To Avoid Nocturnal Hypoglycemia

Nocturnal hypoglycemia (low nighttime blood glucose level) is an important cause of sleep-maintenance insomnia. When there is a drop in the blood glucose level, it causes the release of hormones that regulate glucose levels. These compounds stimulate the brain. They are a natural signal that it is time to eat.

Many people suffer from faulty glucose metabolism, either hypoglycemia or diabetes, because of overeating refined carbohydrates. Good bedtime snacks to keep blood sugar levels steady throughout the night are oatmeal and other whole grain cereals, whole grain breads and muffins, and other complex carbohydrates. These foods will not only help maintain blood sugar levels, they actually can help promote sleep by increasing the level of serotonin within the brain.
