Do Omega-3 Fatty Acids Decrease Risk Of Depression In Women?

Do Happy Fish Make Happy Women?

Author: Dr. Stephen Chaney

Woman playing with autumn leaves The days are getting shorter, and those shorter days can lead to depression. You may have seen the recent headlines saying “Omega-3 fatty acids may decrease the risk of depression in women”. If you suffer from seasonal depression, should you be stocking up on fish oil capsules? Let’s look at the study behind the headlines.

The Theory Behind The Study

Depression appears to be increasing in modern society. For example, between 1991 and 2002, the prevalence of major depression has more than doubled in the United States from 3.3% to 7.1%.

There are many causes of depression, but some experts blame the dramatic increase in omega-6 fatty acids in the diet.  For example, per capita consumption of soybean oil, much of it in processed foods, has increased 1000-fold during the past century. That’s a concern because omega-6 fatty acids interfere with the body’s ability to convert vegetable sources of omega-3 fatty acids into the longer chain omega-3 fatty acids thought to be effective in reducing depression.

This has lead to the hypothesis that omega-3 fatty acids in the diet may help prevent depression, and a number of clinical studies have supported that hypothesis.

How Was The Study Designed?

The study (M. A. Beydoun et al, J. Nutr., doi: 10.3945/jn.113.179119, 2013) looked at 1,746 adults age 30-64 living in Baltimore Maryland. The participants were a representative sample of African Americans and whites, men and women. Omega-3 fatty acid intake was based on two 24-hour dietary recalls. Depressive symptoms were based on something called CES-D, which is a 20 item, self-reporting symptom rating scale.

What Did The Study Actually Show?

The results were pretty dramatic for women:

  • Women with the highest intake of omega-3 fatty acids/day were 49% less likely to suffer from depression than women with the lowest intake.
  • No significant effect of omega-3 fatty acid intake on the prevalence of depression was seen for the men in this study. This was the first study to look at men and women separately, so it’s not yet clear whether this is a true sex-specific difference or simply due to the relatively small sample size and reduced incidence of depression in men.

Limitations Of The Study:

There were numerous limitations to this study, but the most important were:

  • It did not ask whether the participants were taking fish oil supplements, and it did not substantiate the dietary recalls by measuring actual levels of omega-3 fatty acids in the blood.
  • It just measured associations, not cause and effect.

The Bottom Line:

This is not a particularly strong study, but it is consistent with a least half a dozen other studies that have obtained similar results. So, based on the total body of published studies my recommendations are:

1)     If you are a woman and you’re suffering from mild depression you might want to talk with your doctor about increasing your omega-3 fatty acid intake before you start taking an anti-depressive medication. Omega-3 fatty acids may reduce heart disease risk, lower inflammation and provide other benefits. The drugs generally have side effects rather than side benefits.

2)    We don’t have any good data yet on what dose of omega-3 fatty acids are needed, but the 500-1,000 mg/day that the NIH recommends for heart health might be a good starting place.

3)     If you’re a guy, this paper suggests that the jury is out about whether omega-3s can help you with depression. More studies will be required. In the meantime, just remember that omega-3s have lots of other health benefits.

Epsom Salt Bath for Sore Muscles!

Epsom Salt – An Inexpensive “Miracle Cure”

Author: Julie Donnelly, LMT – The Pain Relief Expert

epsom salt bath for sore musclesAn Epsom Salt bath for sore muscles is an old remedy that until recently has been overlooked by modern medicine. For hundreds of years people have used Epsom salt baths for relieving sore muscles, healing cuts, drawing out inflammation, and treating colds.  To many people this has long been a miracle cure, the first “go-to” for pain relief. Research has proven why Epsom Salt works so well, and how to use it so you benefit the most.

Why An Epsom Salt Bath for Sore Muscles Works

Epsom Salt is a combination of magnesium and sulfate. When you are under stress – and who doesn’t have stress in their life – your body becomes depleted in magnesium. Magnesium is a key component in a mood-elevating chemical of the brain called serotonin. Serotonin creates relaxation and a feeling of calm, so it reduces stress, helps you sleep better, improves your ability to concentrate, and lessens the tension of irritability.  It is also a component in the production of ATP (adenosine triphosphate), which produces energy for the cells.

The magnesium in Epsom Salt regulates the activity of over 325 enzymes, helps prevent hardening of the arteries, and is beneficial for muscle and nerve function.  Sulfates improve the absorption of nutrients and flushes toxins out of the body.  All of this is why an Epsom salt bath for sore muscles works.

Massage and Epsom Salt – a “Marriage Made in Heaven!”

Every month I explain how massaging one area of your body will help eliminate or reduce pain. My book (see below) teaches many self-treatments for a long list of aches and pains. Massage has been proven to help with:

  • Joint pain
  • Stiffness
  • Muscle aches
  • Fibromyalgia
  • Insomnia
  • Sports injuries
  • TMJ
  • Headaches
  • and much, much more!

Massage will also force toxins out of your muscles and improve circulation.  Epsom Salt baths are beneficial after a massage because it will remove the toxins out of the body. In the past I had heard that a 15-minute bath was sufficient, but that has changed.  Recently I read an article that explained it takes 40 minutes of soaking to make the transfer complete. Toxins are drawn out and magnesium enters into the body

Self-Massage is Convenient and Easy-to-Do

It’s wonderful to go to a qualified massage therapist and relax while the spasms are worked out of your muscles. However, if you have a stressful job or you love to exercise, you can’t go to a therapist as frequently as you should.  That’s where self-massage becomes a life-saver.

pain free living book coverBefore relaxing in your Epsom salt bath, do the techniques demonstrated in my book, “Treat Yourself to Pain-Free Living” to release the spasms that are causing joint and muscle pain.

As you untie the “knots,” you are releasing toxins into your blood stream and lymphatic system.  A relaxing, 40-minute soak in a tub of comfortably hot water and 2 cups of Epsom Salt will eliminate the toxins from your body.

Life is more stressful than ever before, and you deserve a relaxing break.  Massage and Epsom Salt baths are the perfect beginning to a restful night’s sleep!  Plus, the benefits of both massage and Epsom Salt will improve your health and vitality.

Wishing you well,

Julie Donnelly
