An Apple A Day Keeps The Blues Away

Author: Dr. Stephen Chaney

 

Can food affect your mood? In rural North Carolina you still occasionally see bumper stickers that say “Life Happens”. Of course, the word they use isn’t exactly “Life”, but you get the point.

can food affect your moodWe can’t always control what happens to us. What is important is how we react when bad things happen to us. Do we brush them off and move on, or do we let them get us down? There is no shortage of experts telling us how we can keep the blues away. We are told to count our blessings, meditate, think happy thoughts, develop support groups – the list goes on and on.

But is there perhaps one important parameter that most of these experts are missing? Could the foods we eat make us blue?

The standard American diet (S.A.D.) is high in processed foods, fat (especially saturated and trans fats), refined grains, simple sugars, salt and calories. As I’ve said before, almost anything would be better.

You probably already know that the S.A.D. leads to obesity and a whole host of diseases – including heart disease, cancer and diabetes – just to name a few. But did you know that the S.A.D. could make you sad? That’s what two recent studies suggest.

Can Foods Affect Your Mood? Does Junk Food Make You Sad?

The first study by Akbaralay et al (British Journal of Psychiatry, 195: 408-413, 2009) looked at the dietary patterns and mental health outcomes of 3486 participants in the Whitehall II Prospective Study.

In case you didn’t know it, Whitehall is the central district in London where most of the British government offices are located. So the 3486 participants in this study were bureaucrats. They were middle aged (average age 55.6 years old) office staff (74% men, 26% women) who spent most of their day sitting and really didn’t like their jobs very much. (I made up the part about not liking their jobs. It is hard to imagine that kind of job would be deeply fulfilling, but I’m sure that some of the bureaucrats liked their jobs better than others – which is the whole point of this study.)

At the beginning of the study the participants were given a 127 item food frequency quiz to fill out. Interestingly enough, the food preferences of the participants in this study clustered neatly into two groups.

The diets of the processed foods groups predominantly consisted of sweetened desserts, chocolates, fried foods, processed meats, refined grains and high fat dairy products. In short the diet of this group was pretty similar to what we think of as the Standard American Diet (S.A.D.). In contrast, the diets of the whole foods group consisted mostly of vegetables, fruits, fish and whole grains.

Five years later the study participants were analyzed for depression using a 20 item standardized depression scale.

The results were pretty eye-catching. The processed food group was 58% more likely to suffer from depression than the whole food group! And this was after correction for age, gender, weight, marital status, education, employment grade, physical activity, smoking and diseases (high blood pressure, heart disease, diabetes, and stroke).

The reasons for this astounding correlation between diet and depression are not clear. Can food affect your mood? Does this give us more insight?

The authors speculated that the diets of the whole food group were likely higher in antioxidants, folic acid and omega-3 fatty acids than the diets of the processed food group – and studies have suggested that each of these nutrients may protect against depression.

The authors also suggested that it might be an indirect effect. Diets that are high in saturated fats and refined grains and low in omega-3 fatty acids increase inflammation, and studies have suggested that inflammation can lead to depression.

Can Food Affect Your Mood? Does Healthy Food Make You Glad?

an apple for healthy fruitThe previous study suggested that junk food may make you sad. So you might be asking: “Does that mean that healthy foods can make you glad?” According to one recent study (Br J Health Psychol, Jan 24, 2013, doi: 10.1111/bjhp.12021) the answer may be yes.

A team from the University of Otago in New Zealand enrolled 281 young adults (average age = 20) in a study that looked at the effect of diet on their mood. Each day for 21 consecutive days they recorded their mood and what foods they ate using an online questionnaire. In particular, they reported the number of servings of fresh fruit and vegetables and of several unhealthy foods such as biscuits or cookies, potato chips or French fries and cakes or muffins.

The investigators correlated the foods eaten with the moods reported by the participants on the same day, and again on the day after those foods were eaten. Once again, the results were pretty impressive.

On the days when people ate more fruits and vegetables they reported feeling calmer, happier and more energetic than they did on other days (p = .002 – anything less than .05 is considered a statistically significant difference). And the good effects of fruit and vegetable consumption carried over to the next day as well (p < .001).

Can food affect your mood? While I paraphrased the “apple a day” quote to introduce this study, one apple won’t quite do it. According to this study it takes about 7-8 servings of fruits and vegetables to positively affect mood. In addition, it probably wasn’t just the fruits and vegetables that made the difference. Based on the previous study I would guess that the participants in the study may have eaten other healthy foods such as whole grains and fish on their good days.

Can Food Affect Your Mood?

Taken together these two studies suggest that the next time you feel a little blue you may want to look at your diet. You may want to include a healthier diet along with the meditation and positive thinking.

Of course, these studies both measured correlations between diet and mood, and any good scientist will tell you that correlations do not prove cause and effect. It could be that when people are “down in the dumps” they just naturally reach for junk foods rather than fruits and vegetables.

However, since there is no downside to consuming fruits and vegetables, I feel fully comfortable recommending more fruits and vegetables in our diets. If their health benefits aren’t enough to motivate you, maybe the possibility of improving your mood will!

There are some things you just can’t control. To paraphrase those country songs, you can’t keep your girl and dog from running off. Life happens to all of us. Can food affect your mood? If you want to keep your mood where it should be, you can always reach for those fresh fruits and vegetables, whole grains and sources of omega-3 fatty acids.

 

The Bottom Line

  • Two recent studies have suggested what we eat can affect our mood.
  • The first study showed that people who habitually consumed a diet consisting of sweetened desserts, chocolates, fried foods, processed meats, refined grains and high fat dairy products were 58% more likely to suffer from depression than people who habitually consumed a diet consisting mostly of vegetables, fruits, fish and whole grains.
  • The second study showed that the subjects in their study reported feeling calmer, happier and more energetic on the days when they ate more fruits and vegetables than they did on the days they ate junk foods.
  • Of course, these studies both measured correlations between diet and mood, and any good scientist will tell you that correlations do not prove cause and effect. It could be that when people are “down in the dumps” they just naturally reach for junk foods rather than fruits and vegetables.
  • However, since there is no downside to consuming a healthier diet, I feel fully comfortable recommending more fruits and vegetables, whole grains and omega-3s in our diets. If their health benefits aren’t enough to motivate you, maybe the possibility of their improving your mood will!

One of the Little known Causes of Headaches

Posted August 15, 2017 by Dr. Steve Chaney

Your Sleeping Position May Be Causing Your Headaches!

Author: Julie Donnelly, LMT – The Pain Relief Expert

Can sleeping position be one of the causes of headaches?  

A Sleeping position that has your head tilted puts pressure on your spinal cord and will cause headaches. I’ve seen it happen hundreds of times, and the reasoning is so logical it’s easy to understand.

causes of headachesYour spinal cord runs from your brain, through each of your vertebrae, down your arms and legs. Nerves pass out of the vertebrae and go to every cell in your body, including each of your organs. When you are sleeping it is important to keep your head, neck, and spine in a horizontal plane so you aren’t straining the muscles that insert into your vertebrae.

The graphic above is a close-up of your skull and the cervical (neck) vertebrae. Your nerves are shown in yellow, and your artery is shown in red.  Consider what happens if you hold your head to one side for hours. You can notice that the nerves and artery will likely be press upon. Also, since your spinal cord comes down the inside of the vertebrae, it will also be impinged.

In 2004 the Archives of Internal Medicine published an article stating that 1 out of 13 people have morning headaches. It’s interesting to note that the article never mentions the spinal cord being impinged by the vertebrae. That’s a major oversight!

Muscles merge into tendons, and the tendons insert into the bone.  As you stayed in the tilted position for hours, the muscles actually shortened to the new length.  Then you try to turn over, but the short muscles are holding your cervical vertebrae tightly, and they can’t lengthen.

The weight of your head pulls on the vertebrae, putting even more pressure on your spinal cord and nerves.  Plus, the tight muscles are pulling on the bones, causing pain on the bone.

Your Pillow is Involved in Your Sleeping Position and the Causes of  Headaches

The analogy I always use is; just as pulling your hair hurts your scalp, the muscle pulling on the tendons hurts the bone where it inserts.  In this case it is your neck muscles putting a strain on your cervical bones.  For example, if you sleep on your left side and your pillow is too thick, your head will be tilted up toward the ceiling. This position tightens the muscles on the right side of your neck.

Dozing off while sitting in a car waiting for someone to arrive, or while working for hours at your desk can also horizontal line sleepcause headaches. The pictures above show a strain on the neck when you fall asleep without any support on your neck. Both of these people will wake up with a headache, and with stiffness in their neck.

The best sleeping position to prevent headaches is to have your pillow adjusted so your head, neck, and spine are in a horizontal line. Play with your pillows, putting two thin pillows into one case if necessary. If your pillow is too thick try to open up a corner and pull out some of the stuffing.

If you sleep on your back and have your head on the mattress, your spine is straight. All you need is a little neck pillow for support, and a pillow under your knees.

Stomach sleeping is the worst sleeping position for not only headaches, but so many other aches and pains. It’s a tough habit to break, but it can be done. This sleeping position deserves its own blog, which I will do in the future.

 

Treating the Muscles That Cause Headaches

sleeping position causes of headachesAll of the muscles that originate or insert into your cervical vertebrae, and many that insert into your shoulder and upper back, need to be treated.  The treatments are all taught in Treat Yourself to Pain Free Living, in the neck and shoulder chapters.  Here is one treatment that will help you get relief.

Take either a tennis ball or the Perfect Ball (which really is Perfect because it has a solid center and soft outside) and press into your shoulder as shown.  You are treating a muscle called Levator Scapulae which pulls your cervical vertebrae out of alignment when it is tight.

Hold the press for about 30 seconds, release, and then press again.

Your pillow is a key to neck pain and headaches caused by your sleeping position.  It’s worth the time and energy to investigate how you sleep and correct your pillow.  I believe this blog will help you find the solution and will insure you have restful sleep each night.

Wishing you well,
