We know that there are microbiomes  (communities of bacteria, viruses, fungi) throughout the body, and that there are microbial patterns or "microbial signatures" found in different diseases. But now it appears that there are microbial signatures for a whole list of pain conditions, such as fibromyalgia, complex regional pain syndrome (CRPS), arthritis, and migraine.

In other words, the gut microbiome is different between those with a pain condition compared to healthy individuals without the condition. One question is: does chronic pain cause the microbiome to change or do microbial changes or shifts cause chronic pain? Or does the presence of certain bacteria protect against different pain conditions?

It is still unknown whether probiotic supplementation would help these conditions because the studies are not yet done. But researchers do suggest eating an anti-inflammatory diet - which means a diet rich in fruits, vegetables, whole grains, legumes (includes beans), fish, seeds, nuts, and olive oil. This kind of diet has lots of fiber to feed and support beneficial bacteria.

Also, avoid ultra-processed food as much as possible, including processed meats and soda, because these are associated with harmful bacteria in the gut. Read the ingredient list, and try to avoid foods with ingredients not found in your kitchen (e.g., emulsifiers, colors, natural flavors, artificial flavors, carrageenan, soy lecithin, guar gum)

From Medscape: Gut Microbiome Changes in Chronic Pain — Test and Treat?

A new study adds to what has been emerging in the literature — namely that there appear to be gut microbiome “signatures” for various pain conditions — suggesting that microbiome-based diagnostics and therapeutics may one day be routine for a broad range of pain conditions. ...continue reading "Altered Gut Microbiomes In Persons With Pain Conditions"

One message keeps being supported by research: Eat a diet rich in fruits, vegetables, seeds, nuts, whole grains, legumes, and olive oil. A reason is because this diet is anti-inflammatory. And it turns out that inflammation is at the root of many diseases, including heart disease. And dementia.

A recent study that followed more than 84,342 older adults (60 years or older at the start of the study) found that those who ate an anti-inflammatory diet had a 21% lower chance of developing dementia. They also had larger gray matter volume in the brain, and smaller white matter lesions or spots in the brain (white matter hyperintensity volume). All of the adults had cardiometabolic diseases (e.g., heart disease, diabetes, stroke) at the start of the study.

Other studies have already confirmed that eating an anti-inflammatory diet (e.g., Mediterranean diet) is linked to lower risk of diabetes, heart disease, lower dementia risk, better cognitive function, and better brain aging (as measured by MRI scans).

Eating a healthy diet that dampens inflammation in the body could lower your odds for dementia, especially if you already have heart risk factors, a new Swedish study shows. ...continue reading "Diet and Risk of Developing Dementia"

New research is published every day, but only some studies are big research stories or game-changers. The following are what I consider some of the most memorable studies of 2018 – some in a good way, but some of the others have left me with a sense of horror. I think there will be follow-up research, so keep an eye out for more on these important topics.

Are we heading toward a time in the not so distant future when all men are infertile? (Due to exposure to all the endocrine disruptors around us.) Will All Men Eventually Be Infertile? This was posted September 5, 2018.

Researchers are now seriously investigating and finding evidence that microbes may be causing Alzheimer’s disease. This approach is rapidly finding support in the medical field, and may lead to possible ways to treat or prevent the disease. Possible Herpes Virus Link to Alzheimer’s Disease was posted July 13, 2018, and Herpes Viruses and Alzheimer's Disease on  June 22, 2018.

Type 2 Diabetes May Be Reversed With Weight Loss was posted August 10, 2018. This study and an earlier similar study from 2016 found that losing over 30 pounds over a short period can reverse type 2 diabetes - 46% in the 2018 study and 60% (in people who had it less than 10 years) in the earlier study.

More and more evidence is accumulating that certain diets are anti-inflammatory. Especially beneficial are diets rich in fruits, vegetables, seeds, nuts, legumes (beans), and whole grains - which also have a lot of fiber. This is exciting research because chronic low-grade inflammation is linked to a number of chronic diseases (heart disease, cancer, etc.). Fruits, Vegetables, and Whole Grains Lower Inflammation – posted August 1, 2018.

[Related to this last topic is one of the most eye-opening studies I have ever read on how what one eats has a quick effect on gut microbes and health of the gut (including inflammation of the colon): Changing Diet Has Big Effect On Colon Cancer Risk – posted April 28, 2015.]

Many people have chronic low-grade inflammation, which is associated with a number of chronic diseases, and increased risk of heart disease, cancer, type 2 diabetes, and early death. Thus there is a lot of interest in things a person could do to lower the inflammation.

A number of studies have found a person's general diet may influence chronic low-grade inflammation - either increase it or decrease it, as well as whether they smoke or not. A recent large Swedish study found that persons who ate an anti-inflammatory diet for at least 16 years had a lower risk of dying early from any cause (all cause mortality), as well as dying from cancer, or dying from heart (cardiovascular) disease.

In the study an anti-inflammatory diet was a diet rich in fruits, vegetables, whole grain cereals, whole grain bread, coffee, tea, red wine (low to moderate levels), beer (low to moderate levels), chocolate, nuts, olive and canola oils. These foods are both anti-inflammatory and also rich in anti-oxidants. Pro-inflammatory foods were: red meat, processed red meat, offal, chips, soft drinks. In other studies a pro-inflammatory diet was also one with lots of processed foods, low fiber, and refined grains.
