What Causes Food Cravings?

food cravingsFor some years, researchers had believed that having cravings for a particular type of food may be an indication that you are missing a particular nutrient in your diet. For example, if you crave red meat then you may have an iron deficiency, or if you crave ice cream you must need calcium.

Studies have shown, however, that cravings have nothing to do with a nutritional deficiency, but are actually caused by chemical signals in the brain. Nutritionist Karen Ansel says, “If cravings were an indicator of nutritional deficiency, we’d all crave fruits and vegetables. The fact that we all want high carb, high fat comfort foods, along with the research, is a pretty good indicator that cravings aren’t related to deficiencies.” Yes–it’s really all in your head.

Fat, Sugar and Salt Fuel Food Cravings

When you crave a food, the same reward centers in the brain that are responsible for drug and alcohol addiction are more active: the hippocampus (memory), the insula (emotion and perception) and the caudate (memory and learning). These areas are all very receptive to dopamine and serotonin, neurotransmitters that are responsible for feeling relaxed and calm and which spur reward-driven learning.

The reason you crave things such as ice cream, potato chips and chocolate is that these items are full of fat, sugar and/or salt. Both fat and sugar are involved in an increased production of serotonin and other chemicals that make us feel good.

Food Cravings Are Also Learned

There is a large societal aspect to cravings as well. For instance, women in Japan tend to crave sushi and only 6 percent of Egyptian women say they crave chocolate. Approximately half of American women claim that their cravings for chocolate reach a peak just before their period. However, research has found no correlation between fluctuations in women’s hormones and cravings. In fact, postmenopausal women do not report a large reduction in cravings from their premenopausal levels.

Will Power Alone Is Not Enough

Studies have found that the more people try to deny their cravings, the greater the craving they have for the forbidden food. Researchers suggest that it is better to give in to the craving in a controlled way rather than denying yourself altogether. Just be sure to restrict what you consume to a reasonable amount. If your dopamine receptors are constantly bombarded with high-fat and high-sugar foods (or drugs and alcohol), they shut down to prevent an overload. This makes your cravings even greater and you end up eating more in an attempt get the same reward, but you never really feel satisfied.

How To Bust Your Food Cravings

Exercise and distraction are the two best ways to reduce food cravings. One study found that a morning workout can reduce your cravings for the whole day. Other studies suggest that distracting your mind with other pleasurable stimuli can be effective. For example, smelling a non-food item that you really like can also help. Keep a small vial of your favorite perfume with you when a craving comes on and take a whiff when the craving hits you. It will occupy the aroma receptors that are involved in food cravings.

The Bottom Line

  • In most cases food cravings are not due to nutritional deficiencies. They are a physiological response of the “pleasure center” in the brain to fat, sugar & salt.
  • Food cravings are different in different cultures, which indicates that food cravings are also a learned response.
  • Willpower alone is not sufficient to overcome food cravings.
  • The best strategy to avoid food cravings is to exercise regularly and distract your attention with other pleasurable stimuli.

How to Choose the Right Pillow

Wake Up Each Morning Pain Free

how to choose the right pillow without headachesThe way you sleep is often a key to discovering the cause of headaches and more. If you wake up with neck pain, a headache, or you suffer from ringing in your ears, dizziness, or ear pain, there is a good possibility that it may be caused by the way you are sleeping. Your pillow may be the culprit.  But if you need to know how to choose the right pillow for you, it’s easy.   It just takes a little “investigation.”

 

How to Choose the Right Pillow if You Sleep On Your Side

Your head, neck, and spine need to always stay in a nice straight line, just as it is when you are standing up, but that takes a little thought and understanding of the way you sleep.  So, get comfy in your bed and then notice how your head is resting.

how to choose the right pillow to sleep painfreeIf you sleep on your side, your pillow needs to be just the right size, so your head doesn’t point down toward the mattress (your pillow is too soft) or up to the ceiling (your pillow is too thick). Either of these positions will make the muscles on the side of your neck stay in the contracted position for hours and pull your vertebrae in that direction, especially when you try to turn over to your other side.

Your SCM Muscle May Cause Serious Problems

You also need to notice if you turn your head a bit, especially if you are turning into your pillow or turning your head up toward away from your pillow. In either of these two cases you will be causing your sternocleidomastoid (SCM for short) to be held shortened for hours.

Your SCM originates on your collarbone and inserts into the bone behind your ear.  When it contracts you turn your head to the opposite side. However, if the muscle is tight (for example, when you’ve held your head turned toward one side for an extended period of time) and then you bring your head back so you are facing forward, the tight muscle will pull on the bone behind your ear and cause havoc.

The symptoms for a tight SCM are tinnitus (ringing in the ear), dizziness, loss of equilibrium, ear pain, headaches, pain in the eye and around the skull, pain at the top of the head, and even pain in the throat. Amazing! What’s even more amazing is that it’s rare that this muscle is considered when a medical professional is searching for the cause of your symptoms.

These are the things to know when considering how to choose the right pillow if you sleep on your side.

How To Choose The Right Pillow If You Sleep On Your Back

how to choose the right pillow for sleeping on your backIf you sleep on your back, your head should be on the mattress (not propped up with a pillow) and you should have a tiny support (like a folded washcloth) under your neck.  Or, you can have a wedge pillow that starts at your mid-back and gently raises your entire trunk and head up while still allowing your head and back to be in a straight line.

It’s always a challenge for people who toss and turn during the night, sometimes on their side and sometimes on their back.  The best thing I’ve found for this situation is to have the pillow below shoulder level so when you turn on your side your shoulder will automatically slide to the edge of the pillow while still supporting your head properly, and when you turn onto your back, the pillow will start at shoulder level so your head and neck are supported, but your head is being pushed in a way that causes your chin to move down to your chest.

hip pain causes and treatment pain freeIt’s tricky, but I can personally attest to the fact that it will work.  I can always tell when I’ve had my head tilted (I toss and turn during the night) because I will wake with a headache. When that happens I’m grateful that I know how to self-treat the muscles of my neck and shoulders so the headache is eliminated quickly.  If you already have Treat Yourself to Pain Free Living,  you can self-treat all your neck and shoulder muscles to release the tension.

How To Choose The Right Pillow If You Sleep On Your Stomach

If you sleep on your stomach, this is the one position that is so bad that it behooves you to force yourself to change your position. Your head is turned to the side and held still for hours, putting a severe strain on all your cervical and upper thoracic vertebrae. Not only will this cause headaches, tinnitus, and a list of other pains, but it can cause problems down your entire spine. It can also impinge on the nerves that pass through the vertebrae on their way to your organs.

If you do sleep that way, let me know and I’ll give you some suggestions that work to change your habit of sleeping. It takes time and energy, but the results are worth the effort.

In every case, the way you sleep may cause neck pain that won’t go away until the pillow situation is resolved.

Now you should know how to choose the right pillow for the way you sleep.

Wishing you well,

Julie Donnelly
