Published on Leave a comment on A Daily Glass of Wine Is Associated With A Slower Rate of Aging

Several studies have recently been published that push back at the idea that all alcohol intake has negative health effects. Actual results are more nuanced. High alcohol intake is always harmful, but low to moderate intake appears to be protective for a number of health conditions. In fact, low to moderate intake appears to be better for health than totally abstaining from alcohol.

Similar to research reported in the last post, another recent study looking at alcohol consumption found that low to moderate alcohol consumption has beneficial health effects (is protective). Again, a J curve finding that low to moderate intake best delays biological aging (as measured by biomarker measurements), then alcohol never or rarely consumed, and finally that high intake was harmful - it canceled any alcohol protective effects. In other words, low to moderate alcohol consumption slows down aging.

The most beneficial effects were at 1 to 2 glasses of wine per day. These associations were predominantly in men, and these effects went hand in hand with eating a Mediterranean diet. The Mediterranean diet is eating a diet rich in fruits, vegetables, whole grains, nuts and seeds, beans, and olive oil. The researchers thought that compounds such as polyphenols in wine could play a role in why low to moderate alcohol consumption was beneficial.

From Medical Life Sciences News: Moderate wine intake tied to slower biological aging in men

A large Italian cohort study suggests that moderate wine intake, as defined within a traditional Mediterranean diet, may be associated with slightly slower biological aging in men, whereas total alcohol intake showed a different, less favorable pattern. ...continue reading "A Daily Glass of Wine Is Associated With A Slower Rate of Aging"

Published on Leave a comment on The Foods You Eat and Their Link to Constipation

For years it has been known that increasing the amount of fiber (and drinking enough fluids) in a person's  diet helps to prevent constipation. A recent large multi-year study of 96,000 adults confirmed this: Mediterranean and plant-based diets prevented constipation, and Western and inflammatory diets (low fiber, high ultra-processed foods) raised constipation risk.

Vegetables, cruciferous vegetables (e.g., broccoli), legumes (beans, lentils, chickpeas), and fruits were all associated with reduced risks for constipation. High vegetable and nut consumption was especially good for preventing constipation. Additionally, a low carbohydrate diet showed a slight increased risk for constipation. Eating a diet rich in cereal fibers (e.g., white bread, low fiber breakfast cereals) and ultra-processed foods was linked to constipation.

Besides reducing constipation, many studies show that eating a diet rich in fruits, vegetables, whole grains, seeds, nuts, legumes, such as the Mediterranean diet, is protective for cardiometabolic diseases (e.g., heart disease, heart attack, strokes, kidney disease, and type 2 diabetes), cancer, and even early death. This type of diet is high in fiber, has positive effects on the gut microbiome, and reduces chronic inflammation.

From Science Daily: What 96,000 adults taught scientists about preventing constipation

Chronic constipation becomes more common with age. Researchers from Mass General Brigham conducted a new study examining whether five widely followed diets could help prevent chronic constipation in middle- and older-age adults. The team monitored more than 96,000 participants for several years to see how long-term eating habits influenced the likelihood of developing this persistent gastrointestinal issue. Their analysis showed that people who routinely ate a Mediterranean or plant-based diet experienced a lower incidence of constipation. The findings appear in Gastroenterology. ...continue reading "The Foods You Eat and Their Link to Constipation"

Published on Leave a comment on Preventing Diabetes With A Mediterranean Diet and Increased Physical Activity

There has been lots of research in the past decade over the benefits of eating a diet rich in fruits, vegetables, whole grains, nuts, and legumes, especially a Mediterranean style diet. Health benefits include lowering chronic inflammation and a lower incidence of a number of chronic diseases, including type 2 diabetes.

A recent study conducted in Spain added a twist to this. The researchers found that eating a lower calorie Mediterranean diet and increased levels of physical activity, resulted in a 31% reduction in the development of type 2 diabetes, as well as a greater weight loss and reduction of their waist size. The comparison group were persons who ate a Mediterranean diet, but without lowering their calorie intake or increasing physical activity over the 6 years of the study.

The subjects in this study were 4756 overweight or obese adults with metabolic syndrome, but without prior cardiovascular disease or diabetes - thus a group that was at high risk for developing type 2 diabetes. The calorie reduction goal was to eat about 600 fewer calories per day.

Excerpts from Science Daily: Scientists found a smarter Mediterranean diet that cuts diabetes risk by 31%

Eating a Mediterranean-style diet with fewer calories, adding moderate physical activity, and receiving professional guidance for weight management can lower the risk of developing type 2 diabetes by 31%. That is the key finding of PREDIMED-Plus, a large clinical trial led in Spain by the University of Navarra together with more than 200 researchers from 22 universities, hospitals, and research institutes. The project was carried out in over 100 primary care centers within Spain's National Health System. ...continue reading "Preventing Diabetes With A Mediterranean Diet and Increased Physical Activity"

Stress can have harmful health effects on the body, including the gut microbiome. A recent article in the medical site Medscape reviewed studies of chronic stress and the gut microbiome and found that chronic stress alters the gut microbiome, resulting in gut dysbiosis (the gut microbial community is imbalanced or out-of-whack).

For example, researchers have found alterations in gut microbes, less diversity of microbes, and fewer numbers of certain beneficial microbes  in those with PTSD (post-traumatic stress disorder).

Interestingly, the researchers stress that a good diet (e.g., Mediterranean diet, including fermented foods) will help the gut microbiome, but that there isn't any evidence for probiotic supplements. In other words, don't take store-bought daily supplements, but instead focus on eating well, exercise, and getting enough sleep.

From Medscape: How Chronic Stress Disrupts the Gut Microbiome

Chronic psychological stress is common. A 2023 survey revealed that about one quarter of US adults reported high stress levels, and three quarters reported that chronic stress affects their daily lives.

Emerging evidence suggests that chronic stress not only exacts a high toll on mental health but also can wreak havoc on all levels of gastrointestinal (GI) functioning, all the way down to the microbiome. ...continue reading "Chronic Stress and the Gut Microbiome"

Individuals with psoriasis are always looking for ways to improve the inflammatory skin disorder, especially natural ways. A recent small study found that following a Mediterranean diet is a simple and effective way to reduce the symptoms of psoriasis (red, scaly patches and persistent itching).

Subjects with mild to moderate psoriasis were randomly assigned to one of 2 dietary groups. The group following a Mediterranean diet for 16 weeks had significantly reduced psoriasis severity and symptoms, when compared to the control group that were just told to follow a low-fat diet. Almost half of the Mediterranean group had a 75% reduction of psoriasis severity and symptoms! None of the low-fat diet group had a reduction in psoriasis severity and symptoms.

Additionally, all persons in the study were using their usual topical therapy for their psoriasis. The improvements in the Mediterranean diet group occurred without significant weight loss.

The Mediterranean diet is rich in fruits, vegetables, whole grains, seeds, nuts, legumes, fish, and olive oil. In the study's Mediterranean diet group, the participants were not only given nutritional advice, but also a weekly provision of extra virgin olive oil. This diet is anti-inflammatory, which is why it may be so beneficial to those with psoriasis.

Published on Leave a comment on Diet and Risk of Developing Dementia

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).

Published on Leave a comment on A Mediterranean Style Diet Feeds Beneficial Gut Bacteria

The incidence of both intestinal bowel diseases (IBD) and colorectal cancer is rapidly increasing in developed countries (e.g., US, Canada, Europe). There are many theories over why this is occurring, with most researchers thinking a person's diet plays a role. A big suspect in promoting IBD and colorectal cancer is the Western diet, which has lots of ultra-processed foods and is also low in fiber.

A recent large study looked at 6 major diets and how they impact the gut microbiome. The six dietary patterns were: Western diet, Mediterranean diet, high-fiber diet, plant-based diet, high protein diet, and ketogenic diet.

And surprise, surprise - eating a Western diet resulted in having an increase in gut bacterial species linked to chronic inflammation, heart disease, colorectal cancer, IBD, and diabetes. The Mediterranean style diet had an increase in bacterial species linked to a lower risk of cardiovascular disease, IBD, and type 2 diabetes. In fact, all 6 diets had distinct bacterial profiles in the gut.

Bottom line: The foods a person eats can either feed and nourish beneficial bacteria or harmful bacteria (linked to cancer and IBD). Best for health is a Mediterranean style diet (lots of fruits, vegetables, whole grains, legumes, seeds, nuts), and avoiding ultra-processed foods. You are what you eat!

Published on Leave a comment on Study Finds Mediterranean Diet Lowers the Risk of Developing Heart Disease In Women

A recent study was good news for those wishing to lower their chances of developing heart disease (cardiovascular disease) without the use of medications. Instead, focus on the foods you eat, specifically those in a Mediterranean-style diet.

The Univ. of Sydney researchers did an analysis of 16 existing studies (with 722,495 women) and found that women following a Mediterranean diet lowered their odds of developing heart disease by 24% and lowered their risk of early death by 23%.

In this study, a Mediterranean diet meant eating a diet rich in fruits, vegetables, whole grains, legumes, nuts, seeds, extra virgin olive oil. Moderate amounts of seafood, low to moderate in wine consumption, and low in red/processed meats, dairy products, animal fat, and processed foods.

Why is the Mediterranean diet beneficial? The diet focuses on whole foods that are also rich in fiber, antioxidants, has an increased intake of all sorts of nutrients (vitamins, minerals, flavanols, etc.), less oxidative stress, it's anti-inflammatory, reduced glycemic load, boosts the immune system, and feeds the beneficial microbes in our gut microbiome.

Interestingly, studies find that frequent consumption of extra virgin olive oil (EVOO) lowers the risk of death from several diseases (heart disease, cancer, neurogenerative disease, and respiratory disease), lowers the incidence of breast cancer, and promotes healthier brain aging. A Mediterranean diet is associated with numerous health benefits (e.g., lower dementia risk) besides a lower heart disease risk.

These findings are important because heart disease is the leading cause of death globally, according to the World Health Organization. According to the CDC, it is the number 1 killer of women in the United States.

Published on Leave a comment on Eating Healthy Foods Lowers Risk of Chronic Diseases

Want to improve your odds of not getting a chronic disease, such as heart disease or diabetes? A recent study found that following any healthy dietary pattern, whether Mediterranean or DASH or Diabetes Risk Reduction Diet or other similar healthy dietary styles, are all linked to a lower risk of chronic diseases.

These healthy dietary patterns all stress fruits, vegetables, whole grains, seeds, nuts legumes, but they vary in minor ways, e.g., whether salt, coffee, tea, or wine is allowed. People weren't following specific diets over the 3 decades of the study, but it's how they generally ate - their dietary pattern.

The Harvard T.H. Chan School of Public Health researchers found that persons who were in the top 10% of a healthy dietary pattern, no matter which one, were compared to persons in the bottom 10% of that dietary pattern. Overall they found that being near the top of any of the healthy dietary patterns was associated with a lower disease risk.

Interestingly, larger amounts of coffee, whole grains, wine and desserts had lower risk of associated major chronic diseases.

Eating some foods frequently were associated with developing major chronic diseases, such as processed meats, energy drinks, french fries, red meat, and eggs.

Published on Leave a comment on A Mediterranean Style Diet Is Associated With A Lower Dementia Risk

Another large study found that eating a Mediterranean diet is beneficial to health - specifically, that it is associated with a decreased risk for dementia. As much as 23% lower (compared to those who didn't eat a Mediterranean style diet)! It didn't matter if a person had a genetic risk for dementia or not - diet was more important.

By the way, other studies also find that eating a Mediterranean style diet has benefits for the brain and body.

A Mediterranean style diet is one rich in fruits, vegetables, whole grains, legumes (beans, lentils), nuts, seeds, herbs, spices, and olive oil. Some lean meat, especially chicken, and fish. This way of eating is high in fiber (good for health!). Try to avoid processed meats, highly processed foods, fast food, and hydrogenated oils. Eat less meat in general.
