Published on Leave a comment on Health Benefits From Regularly Eating Eggs

Remember when for years eating eggs was viewed as unhealthy? And people were told to only eat egg whites? Well, well... how views have changed. Another recent study of 8756 older adults found that frequently eating eggs has health benefits - it is associated with a lower incidence of heart-disease related death and death from any cause.

How much lower? The study found a 29% lower incidence of cardiovascular disease death in relatively healthy older (70+ years) adults who ate eggs 1 to 6 times per week, when compared to adults who didn't eat eggs or ate them infrequently. The 1 to 6 times per week egg eaters also had a 17% lower rate of death from any cause, when compared to those who ate eggs infrequently or not at all.

Eggs are a great food. They are a good source of protein and essential nutrients, such as B vitamins, folate, unsaturated fatty acids, choline (very important for the brain!), selenium, fat-soluble vitamins (E, D, A, and K), and numerous other minerals and trace elements. A large egg is about 72 calories and 6 grams of protein.

Other studies have similar findings, as well as a lower risk of diabetes and a lower risk of hemorrhagic stroke in those consuming eggs frequently.

For those with a sweet tooth, maple syrup appears to be a healthier choice than sugar. A recent study found a number of health benefits in individuals who consumed some maple syrup daily in place of refined sugar.

Canadian researchers found that replacing just 2 tablespoons of refined sugars with 2  tablespoons of maple sugar daily for 8 weeks had significant beneficial health effects. Regular ingestion of maple syrup resulted in their bodies handling sugar after meals better (improved glycemic response), their blood pressure was significantly lower, their abdominal fat was reduced, an increase in beneficial gut species (bacteria linked with health), and a decrease in some gut bacterial species linked to inflammation and metabolic disorders.

In other words, there was a significant reduction in key cardiometabolic risk factors. By the way, similar results have been found in animal studies. This could be because maple syrup is a minimally processed sweetener rich in a number of beneficial nutrients and polyphenols. It's just boiled maple tree sap, with nothing added.

What made this study convincing was that persons were randomized to different groups (maple sugar or placebo), it was double-blind (no one knew what they were ingesting), and it it was a crossover study (meaning all participants were in both groups for 8 weeks with a gap in the middle). All participants were overweight adults with mild cardiometabolic alterations at the start of the study.

From SciTechDaily: Reducing Abdominal Fat: Researchers Uncover Surprising Health Benefits of Maple Syrup

A study published in The Journal of Nutrition reveals that replacing refined sugars with two tablespoons of maple syrup can significantly improve several cardiometabolic risk factors, such as blood sugar levels, blood pressure, and abdominal fat composition. This was the first placebo-controlled human clinical trial exploring the potential health benefits of maple syrup consumption. ...continue reading "Health Benefits of Maple Syrup"

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 More Reasons To Avoid Artificial Sweeteners

The artificial sweetener erythritol is added to many foods. However, this sugar substitute (which is often blended with stevia) may cause health problems . A recent small study found that consuming typical "sugar-less" foods, such as erythritol sweetened drinks or erythritol sweetened muffins, more than doubled the risk of blood clotting in healthy volunteers.

After consuming the drinks, their bodies made platelets (a type of blood cell) more active, which can raise the risk of blood clots. This did not happen after consuming regular sugar (glucose).

The researchers suggest instead of artificial sweeteners, to use sugar, honey, or fruit, but in moderation.

From Medical Xpress: New study adds to increasing evidence that sugar substitute erythritol raises cardiovascular risk

New Cleveland Clinic research shows that consuming foods with erythritol, a popular artificial sweetener, increases the risk of cardiovascular events such as heart attack and stroke. The findings, from a new intervention study in healthy volunteers, show erythritol made platelets (a type of blood cell) more active, which can raise the risk of blood clots. Sugar (glucose) did not have this effect. ...continue reading "More Reasons To Avoid Artificial Sweeteners"

Published on Leave a comment on Eating Ultra-Processed Plant-Based Foods Is Not Healthy

Eating plant-based foods has health benefits. But only if it's from real foods, and not ultra-processed. A recent study found that the more not ultra-processed plant-based foods a person ate (and the less ultra-processed plant-based foods), the lower their risk of cardiovascular disease  and early death.

The results show that eating minimally processed food is heart protective. And the reverse is also true: higher consumption of plant-based ultra-processed foods was associated with a greater risk of heart disease (including heart attacks and strokes) and early death from heart disease.

Read the ingredient lists! When there are ingredients that are not normally found in your kitchen (e.g., carrageenan, artificial or natural flavors, titanium dioxide, soy lecithin, high-fructose corn syrup, cellulose) - then they are ultra-processed foods. Ultra-processing strips away a food's nutrients, as well as fiber.

Yes, trying to lower consumption meat consumption and eating more plant-based foods is a good goal. But...Many meat-free foods (e.g., boxed macaroni and cheese), dairy substitutes, and plant-based "meats" are not healthy. Lots of chemicals were added to make it more meat-like or a dairy substitute - thus they are ultra-processed foods.

Packaged breads, buns, cakes, cookies and soda are meat free and plant-based foods, but they generally are ultra-processed.

Bottom line: Try to eat more fresh, frozen, or minimally plant-based foods. This is a diet rich in whole grains, fruits, vegetables, legumes (beans), seeds, nuts. A good example is a Mediterranean-style diet, which has been shown to have many health benefits.

From Washington Post: When plant foods are ultra-processed, the health benefits disappear

Eating a plant-based diet is good for your health, but not if those plant foods are ultra-processed, a new study has found.

The findings show that all plant-based diets aren’t the same, and that plant foods can have very different effects on your health depending on what manufacturers do to them before they reach your plate. ...continue reading "Eating Ultra-Processed Plant-Based Foods Is Not Healthy"

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 1 Comment on Study Finds That Xylitol Is Linked To A Higher Risk of Stroke and Heart Attack

The ingredient xylitol is added to a number of products, but recent studies find it to have no health benefits (in sinus products) or even associated with health harms. A recent study found that xylitol is linked with an increased risk of heart attack and stroke.

Xylitol is used in a large variety of products, especially as a sugar substitute (artificial sweetener). However, the research shows that xylitol it is prothrombotic - it causes platelets to clot, and increases the risk of thrombosis or clotting of the blood.

Interestingly, when comparing xylitol vs a glucose (sugar) in a study - drinking a xylitol sweetened drink increased every measure of platelet clotting in humans, but the glucose-sweetened drink did not.

New discoveries about our gut microbiome (the community of viruses, bacteria, fungi) keep occurring. There is growing evidence that certain bacterial species in the gut are associated with cholesterol levels and heart disease.

Adding to the evidence, a recent study found that people with higher levels of several species of Oscillibacter bacteria had lower cholesterol levels than people without or diminished levels of these bacteria. The researchers than  found (in the lab) that these species of Oscillibacter bacteria actually take up and metabolize artery-clogging cholesterol, which could explain the lower cholesterol levels.

By the way, other species (e.g., Eubacterium coprostanoligenes)  were also associated with lower cholesterol levels in the study. The same people with higher levels of beneficial bacteria also had greater diversity of gut bacteria, which is considered a sign of gut health.

Species of Oscillibacter bacteria are not available in any supplements at this time. You'll just have to eat a diet that feeds and nurtures beneficial gut microbes.

And what is a health-promoting diet? A recent study found that a diet rich in fruits, vegetables, whole grains, nuts, seeds, legumes, and olive oil promotes healthy bacteria in the gut, which are associated with good health. This also is a diet high in fiber. Think along the lines of a Mediterranean diet.

From Science Daily: Scientists link certain gut bacteria to lower heart disease risk

Changes in the gut microbiome have been implicated in a range of diseases including type 2 diabetes, obesity, and inflammatory bowel disease. Now, a team of researchers at the Broad Institute of MIT and Harvard along with Massachusetts General Hospital has found that microbes in the gut may affect cardiovascular disease as well. In a study published in Cell, the team has identified specific species of bacteria that consume cholesterol in the gut and may help lower cholesterol and heart disease risk in people. ...continue reading "Certain Gut Bacteria Are Associated With Lower Cholesterol Levels"

Published on Leave a comment on Over 30 Health Harms Associated With Ultra-Processed Foods

The studies finding health harms from ultra-processed foods keep coming. Ultra-processed foods are food products manufactured with all sorts of ingredients (additives) not normally found in our kitchens. Examples of such ingredients are: emulsifiers, carrageenan, mono- and diglycerides, soy lecithin, polysorbate, cellulose, colors, titanium dioxide, high fructose corn syrup, hydrogenated oils, dextrose, whey protein, nitrates, flavors (artificial and natural), colors, etc.

A large review of studies (none of which were affiliated with companies producing ultra-processed foods) found that eating ultra-processed foods are linked to over 30 health harms. Some of the health harms had especially strong associations: early death, death from heart disease (cardiovascular disease), type 2 diabetes, adverse sleep outcomes, wheezing, and obesity. In general, the more ultra-processed foods one ate, the higher the risk for harms.

Bottom line: Read ingredient lists, and try to avoid ultra-processed foods. Even foods such as cereals can have one that is ultra-processed (a formulation of ingredients that result from industrial processes) next to one that only has natural real ingredients without any additives.

From Medical Xpress: Consistent evidence links ultra-processed food to over 30 damaging health outcomes

Consistent evidence shows that higher exposure to ultra-processed foods is associated with an increased risk of 32 damaging health outcomes including cancer, major heart and lung conditions, mental health disorders, and early death. ...continue reading "Over 30 Health Harms Associated With Ultra-Processed Foods"

Published on Leave a comment on ADHD Medications and Increased Risk of Heart Disease

Many children and adults have been diagnosed with ADHD (attention deficit hyperactivity disorder) and been prescribed medications as a result. Medications that are taken daily for years. The big question is: Are there long-term health effects from ADHD medications?

A large study looking at long-term use of ADHD medications found an increase in cardiovascular disease, particularly hypertension and arterial disease, when compared to persons with ADHD who did not take medications. The longer the medications were taken, the higher the risk for hypertension and arterial disease.

In the 14 year follow-up, the researchers found that each 1 year increase of ADHD medication was associated with a 4% increased risk of heart disease (cardiovascular disease). The risk was higher for stimulant medications (e.g., methylphenidate, lisdexamfetamine) than for non-stimulant medications.

From Medical Xpress: Long-term ADHD medication use associated with increased cardiovascular disease

Research led by the Karolinska Institutet, Sweden, has found an increased risk of cardiovascular disease associated with long-term ADHD ( attention-deficit/hyperactivity disorder) medication use. Specific associations with different medications and dosages were connected to hypertension and arterial disease, with a higher risk observed for stimulant medications. ...continue reading "ADHD Medications and Increased Risk of Heart Disease"
