Published on Leave a comment on Blocking Inflammation After An Injury Can Result In Persistent Pain

The usual medical advice to take non-prescription anti-inflammatory drugs (e.g., Advil, Aleve, aspirin) or steroids for pain and inflammation from an injury may actually backfire down the line. A recent study found that blocking inflammation from an injury actually causes an increase in pain and inflammation 3 months later (may become chronic pain), and which is harder to treat.

The McGill University researchers found that drugs that inhibit inflammation interfere with the natural recovery process, thus increasing the odds for chronic pain.  They found that neutrophils (a type of white blood cell that helps the body fight infection) play a key role in resolving pain.

"Neutrophils dominate the early stages of inflammation and set the stage for repair of tissue damage. Inflammation occurs for a reason, and it looks like it's dangerous to interfere with it," said Professor Mogil, one of the researchers.

The researchers looked at lower back pain and temporomandibular disorder (TMD) and found that the results appeared to hold for both mice and humans.

Bottom line: After an injury such as lower back pain, non-prescription medicines that only block pain are OK to take, for example, Tylenol (Acetaminophen) . It's the anti-inflammatory medicines that could lead to persistent (chronic) pain three months later. View inflammation as part of the healing process - don't want to interfere with that.

Excerpts from Medical Xpress: Discovery reveals blocking inflammation may lead to chronic pain

Using anti-inflammatory drugs and steroids to relieve pain could increase the chances of developing chronic pain, according to researchers from McGill University and colleagues in Italy. Their research puts into question conventional practices used to alleviate pain. Normal recovery from a painful injury involves inflammation and blocking that inflammation with drugs could lead to harder-to-treat pain. ...continue reading "Blocking Inflammation After An Injury Can Result In Persistent Pain"

Published on Leave a comment on Plant-based Diets and Lower Risk Of Type 2 Diabetes

Some good news. A recent large study found that a healthy diet rich in plant-based foods can lower your risk of getting type 2 diabetes.

Researchers at the Harvard T.H. Chan School of Public Health found that a healthy diet rich in plant-based foods (fruits, vegetable, legumes, nuts, whole grains, coffee) resulted in plasma metabolite profiles that were associated with a lower risk of type 2 diabetes.

In other words, differences in the chemical make-up of foods means that what a person eats is reflected in their metabolite profile. The 200+ plasma metabolites include lipids, cholesterol, glycerides, phospholipids, fatty acids, inflammation, amino acids, and these give a metabolic profile.

Bottom line: A diet rich in plant-based foods is good for your health in many  ways, including lowering your risk of type 2 diabetes. One such example of a good way to eat (dietary pattern) is a Mediterranean style diet (rich in whole grains, legumes, fruits, vegetables, nuts, seeds, fish, and olive oil).

From Medical Xpress: New study reveals that healthy plant-based diets are associated with a lower risk of developing diabetes

New research published in Diabetologia (the journal of the European Association for the Study of Diabetes [EASD]) finds that the consumption of healthy plant-based foods, including fruits, vegetables, nuts, coffee, and legumes, is associated with a lower risk of developing type 2 diabetes (T2D) in generally healthy people and support their role in diabetes prevention.

Published on Leave a comment on Ordinary Daily Activities Can Have Health Benefits

The studies are coming fast and furious about how all daily physical activity has health benefits. Ordinary daily activities that cause a person to move, such as housework, vacuuming, washing dishes, gardening, walking, cooking, even showering - all count. (On the other hand, reading and computer use do not.)

A recent study by University of California researchers found a higher rate of heart disease, stroke, and death in older women who have less than 2 hours each day of "daily life movement" (daily physical activities) compared to those who have more than 4 hours per day. At the start of the study 5416 women (63 years or older, and without heart disease) wore an accelerometer to measure their daily movements for 1 week, and then their health was followed for more than 6 years.

The researchers found that higher amounts of daily life movement or "being up and about" were associated with a lower risk of major cardiovascular disease, coronary heart disease, stroke, and cardiovascular death in older women. In other words - all movement (and not just exercise) counts towards cardiovascular disease prevention.

From Science Daily: Daily activities like washing dishes reduced heart disease risk in senior women

Seniors take note, running or brisk walking is not the only way to reduce the risk of heart disease. Simply being "up and about" performing routine activities, referred to as daily life movement, including housework, gardening, cooking and self-care activities like showering can significantly benefit cardiovascular health. ...continue reading "Ordinary Daily Activities Can Have Health Benefits"

Published on Leave a comment on Vitamin D Supplements and Autoimmune Disease

Yesterday's post was about how several well-done large studies did not find the health benefits from vitamin D supplements that the researchers had hoped for. In one of the studies (the VITAL trial) discussed yesterday, Vitamin D supplements did not prevent cancer or cardiovascular events (e.g., stroke, heart attack), which was the focus of the study.

But... one positive finding (in a separate analysis of the study results) did come out of the study: vitamin D supplements reduced the incidence of autoimmune disease by 22% over the 5+ years of the VITAL trial. This included rheumatoid arthritis, polymyalgia rheumatica, autoimmune thyroid disease, and psoriasis.

The more than 25,000 participants (all older than 50 years) took vitamin D 2000 IUs daily or 1 g marine omega-3 fatty acids (fish oil) daily,  or both, or none for more than 5 years. Only the vitamin D supplementation (whether taken alone or with fish oil) had a statistically significant health effect.

From Medical Xpress: Study finds vitamin D supplements with or without Omega-3s decreased risk of autoimmune diseases

Autoimmune diseases (AD) such as rheumatoid arthritis, polymyalgia rheumatica, autoimmune thyroid disease and psoriasis, are a leading cause of morbidity and mortality as people age. Few effective treatments are available for AD, but some preclinical studies have hinted that supplements, including vitamin D and omega-3 (or n-3) fatty acids, may have beneficial effects. In a new study published in BMJ, investigators from Brigham and Women's Hospital evaluated whether taking vitamin D and/or omega fatty acid supplements could affect rates of AD.  ...continue reading "Vitamin D Supplements and Autoimmune Disease"

Published on Leave a comment on Dining Early Is Healthier Than Close to Bedtime

An easy-peasy way to lower your risk for type 2 diabetes may be to not eat late dinners. Research conducted in Spain found that eating a meal an hour before bedtime decreases insulin secretion, impairs and decreases glucose tolerance, and so increases type 2 diabetes risk.

Lead author Marta Garaulet, PhD said: "We found that late eating disturbed blood sugar control in the whole group." The study had 845 participants, none with diabetes, all living in Spain. Melatonin levels (which rise naturally in the 2 hours before bedtime) were involved - so researchers say don't eat a meal then. Those with a certain gene variant had more disturbed blood sugar control than those without the gene.

Bottom line: Don't eat a meal in the 2 hours before bedtime. 

From Medscape: Eating Dinner Late Ups Diabetes Risk; Melatonin Involved

Eating dinner close to bedtime when endogenous melatonin levels are high is associated with decreased insulin secretion and decreased glucose tolerance, which increase the risk of type 2 diabetes. ...continue reading "Dining Early Is Healthier Than Close to Bedtime"

Published on Leave a comment on Too Many American Adults Are Physically Inactive

The CDC (Centers for Disease ) recently released another bit of gloomy news about Americans - that 25% of adults report being physically inactive. Being physically inactive means that they don't do any physical activities outside of work. This means no walking for exercise, no gardening, no bicycling, nothing.

There were differences according to where a person lives - from a low of physical inactivity of 17.7% of people in Colorado to a high of 49.4% in Puerto Rico. There were regional variations with the South reporting 27.5% of adults being physically inactive and with the West the least (21.0%).

There were also differences in physical inactivity levels by race and ethnicity. Overall, Hispanic adults (32.1%) reported the most physical inactivity outside of work, and non-Hispanic Asian adults the least (20.1%). The results were from large-scale health-related telephone surveys (called Behavioral Risk Factor Surveillance System or BRFSS), with more than 400,000 adults interviewed each year.

Why the concern with physical activity? Numerous studies find that physical activity results in better health, for example in lower risk of diabetes, better brain health, and lower risk of heart disease. Some researchers call exercise or physical activity a "magical bullet" in warding off heart disease.

Dr. Ruth Peterson, Director of CDC's Division of Nutrition, stated that:

“Getting enough physical activity could prevent 1 in 10 premature deaths. Too many people are missing out on the health benefits of physical activity such as improved sleep, reduced blood pressure and anxiety, lowered risk for heart disease, several cancers, and dementia (including Alzheimer’s disease)."

How much physical activity is best? CDC guidelines state that adults should have at least 150 minutes (2 hours and 30 minutes) to 300 minutes of moderate intensity workouts each week. This includes brisk walking! All physical activity counts, for example, bicycling, gardening, fast dancing, exercise classes.

Published on Leave a comment on Most Americans Are Not Eating Enough Fruits and Vegetables

Recently the CDC (Centers for Disease Control and Prevention) released the  depressing news that very few Americans are eating recommended amounts of fruits and vegetables. Many studies show that eating several servings each day of fruits and vegetables has all sorts of health benefits (e.g., live longer, lower inflammation, lower risk of diabetes and some cancers).

The CDC reported in the Jan. 7, 2022 CDC weekly report that surveys of 294,566 adults in 2019 found that only 12.3% of American adults met fruit intake recommendations, and 10.0% of adults met vegetable intake recommendations.

What are the daily recommendations for fruits and vegetables? According to the CDC, current Dietary Guidelines for Americans advise eating more fruits and vegetables as part of a healthy dietary pattern. This means adults should consume 1.5 to 2 cups of fruit and 2 to 3 cups vegetables daily. (Note: A serving is usually about 1/2 cup of fruits or vegetables.)

Why should you follow these guidelines? The CDC states: "A healthy diet supports healthy immune function and helps to prevent obesity, type 2 diabetes, cardiovascular diseases, and some cancers." Also, having "some of these conditions can predispose persons to more severe illness and death from COVID-19."

Another reason, and one that they don't mention is research finding that eating more fruits and vegetables daily (as part of a healthy diet such as the Mediterranean diet) also improves the gut microbiome. What you eat feeds gut microbes - so you want to feed beneficial microbes associated with health, and not those microbes associated with chronic inflammation and some chronic diseases (e.g. heart disease, diabetes, some cancers).

Published on 1 Comment on Some Emulsifiers Harm the Gut Microbiome

Emulsifiers are in many of the processed foods we buy. They are added to the foods to enhance texture and extend shelf life. Animal and human studies find that some emulsifiers (e.g., soy lecithin, carrageenan, polysorbate-80) can promote gut inflammation and alter the gut microbiome in a negative or harmful way. Recent research adds to this list the common emulsifier carboxymethylcellulose (CMC), also known as cellulose gum.

A small study randomly assigned 16 healthy adults to either an emulsifier-free diet or an identical diet with added 15 g per day of CMC for 11 days. No one knew what diet they were eating, and for those 11 days the participants were inpatient - thus no chance for cheating or altering the diet. Extensive testing (even biopsies on day 1 and 11!) was done before, during, and after the study. The Univ. of Pennsylvania researchers found that CMC resulted in several harmful changes, including a negative effect on the gut microbiome (microbial community of bacteria, viruses, fungi).

Results: The researchers found that CMC increased abdominal discomfort after meals, disturbed the gut microbial community and reduced its diversity (not good!). It resulted in reductions of short-chain fatty acids and free amino acids (thus impacted how nutrients are absorbed). One of the beneficial microbes associated with good health, and that was reduced in number was Faecalibacterium prausnitzii.

Two of the subjects who had CMC in their foods had increased microbial "encroachment into the normally sterile inner mucus layer" of the gut, which is a central feature of chronic inflammation diseases (e.g., IBD, type 2 diabetes). They also had large "alterations in microbiota composition". This means that there is variation in how people respond to the emulsifier CMC, with some people more sensitive than others.

The scary part is that the intestinal changes happened after just 11 days with a daily intake of 15 g of CMC - a dose that is approximately the total emulsifier consumption for a person whose diet is largely highly processed food. Yes, that is many of us eating a Western style diet (e.g., highly processed foods, and low in fiber, fresh fruits, vegetables, and whole grains). The scientists believe that long-term consumption of emulsifiers, because they result in gut microbial disruption and inflammation, are contributing to chronic diseases.

Bottom line: Read the ingredients list on food labels. Try to avoid foods that have ingredients listed that you wouldn't normally have in your kitchen. That means soy lecithin, CMC, cellulose gum, carrageenan, artificial colors. Even "natural flavors" (which are laboratory concoctions) should be avoided as much as possible.

From Medical Xpress: Ubiquitous food additive alters human microbiota and intestinal environment

New clinical research indicates that a widely used food additive, carboxymethylcellulose, alters the intestinal environment of healthy persons, perturbing levels of beneficial bacteria and nutrients. These findings, published in Gastroenterology, demonstrate the need for further study of the long-term impacts of this food additive on health.  ...continue reading "Some Emulsifiers Harm the Gut Microbiome"

Published on Leave a comment on Study Finds Lower Risk of Breast Cancer With Higher Sunlight Exposure

We've all been warned over and over to avoid sunlight in order to avoid skin cancer, but... conflicting with that advice are studies linking higher sunlight exposure to lower levels of other cancers, health benefits (e.g. lower blood pressure), and early death (mortality). One such recent study found that higher sun exposure over the years is associated with a lower risk of breast cancer in women.

The Univ. of Buffalo and Univ. of Puerto Rico researchers conducted the study in Puerto Rico, where people live with high year round sun exposure. 635 women participated in the study.

Published on Leave a comment on Olive Oil Lowers the Risk of Death From Several Diseases

Once again research finds health benefits from consumption of olive oil. A recent large study found that consuming more than 1/2 tablespoon of olive oil per day lowered the risk of death from heart disease, cancer, neurogenerative disease, and respiratory disease.

The Harvard T.H. Chan School of Public Health researchers also found that increasing intake of olive oil in the diet (replacing margarine, butter, mayonnaise, and dairy fat with 2 1/4 teaspoons or 3/4 tablespoons olive oil) lowers risk of early death in general. The study participants were followed for 28 years, and diet was assessed every 4 years.

Earlier studies found that the best kind of olive oil to consume is extra virgin olive oil (EVOO). Extra virgin olive oil is considered anti-inflammatory, and contains oleocanthal, which has anticancer effects. Health benefits are both if eaten as is (e.g., dunk bread, in salad dressings) or cooked (e.g. roast vegetables, in sauces, cooking foods) - and this result was also found in this recent study.

From Science Daily: Higher olive oil intake associated with lower risk of CVD mortality

Consuming more than 7 grams (>1/2 tablespoon) of olive oil per day is associated with lower risk of cardiovascular disease mortality, cancer mortality, neurodegenerative disease mortality and respiratory disease mortality, according to a study publishing today in the Journal of the American College of Cardiology. The study found that replacing about 10 grams/day of margarine, butter, mayonnaise and dairy fat with the equivalent amount of olive oil is associated with lower risk of mortality as well.  ...continue reading "Olive Oil Lowers the Risk of Death From Several Diseases"
