Glass of whole milk

For years health professionals advised everyone to avoid whole fat dairy products. They said all that saturated fat was unhealthy, but studies from the last decade is proving that advice wrong. Recent studies have found that consuming full-fat dairy products, including whole milk, is associated with a number of health benefits.

The latest is a Canadian study that found health benefits (e.g., lower blood pressure, and increased ingestion of protein, vitamin D, and calcium) from consuming three servings of full-fat dairy products daily for 12 weeks. The full-fat dairy products were milk, yogurt, and cheese. There were no negative health effects (e.g., in weight, cholesterol levels, lipids, insulin resistance) when compared to two other groups that did not consume full-fat dairy.

Interestingly, all the study participants had metabolic syndrome, so the researchers were pleasantly surprised to see health benefits and no adverse effects from consuming all that full-fat dairy.

Bottom line: Stop avoiding full-fat dairy! Dairy products are healthy for us.

Published on Leave a comment on Food Additives and Hypertension

Hypertension (high blood pressure) is a big problem in adults. A large European study found that eight preservative food additives are associated with high blood pressure and heart (cardiovascular) disease. And the more a person eats additives in their daily diet (meaning more ultra-processed foods), the greater the risk of developing hypertension and heart disease.

The most problematic of the preservative food additives in this European study included: potassium sorbate, potassium metabisulphate, sodium nitrite, ascorbic acid, sodium ascorbate, sodium erythorbate, citric acid, extracts of rosemary. These results suggest that a higher intake of preservative food additives means a greater intake of ultra-processed food, which ultimately is not good for the health (increased risk of high blood pressure and heart disease).

Note that in the list of US problematic food additives may be somewhat different, because different additives may be more common. But all are indications of ultra-processed foods.

Bottom line: Nutrition matters! Eat as many minimally processed foods as possible. Also, read ingredient labels and try to avoid products that contain ingredients that are not normally found in a kitchen (e.g., xanthan gum, carrageenan).

The evidence keeps piling up that certain foods are associated with health, while other foods (e.g., soda, ultra processed foods) are associated with chronic diseases. A recent article reported the results of several studies finding certain foods linked to cardiovascular health, including lowering blood pressure.

But guess what? They are popular foods available to everyone - cocoa, green tea, black tea, apples, grapes, and berries.

There is strong evidence certain plant compounds (flavan-3-ols, also known as flavanols or catechins) in these foods have beneficial effects on cardiovascular health. These compounds can lower blood pressure and improve endothelial function (functioning of the blood vessels). Two to three cups of tea daily! One to two servings of dark chocolate daily! Instead of chips for a snack, have an apple.

By the way, rather than focusing on eating just certain foods, it's better to improve your entire diet by eating more fruits, vegetables, whole grains, legumes, seeds, and nuts. All these foods are linked to good health and are considered part of a heart-healthy diet.

From Medscape: From Apples to Cocoa: Everyday Foods Linked to CV Benefits

The term “healthy diet” is often used but frequently remains vague. This is why scientific research into specific food components with preventive potential is gaining importance. Current studies suggest that certain plant compounds found in everyday foods such as apples, cocoa, and tea may have beneficial effects on cardiovascular (CV) health. ...continue reading "Common Foods Linked to Improved Heart Function"

Published on Leave a comment on A Walk In the Woods Is Good For Us

After the recent incredibly hot and steamy week, it is nice to read something positive about nature. A recent review of studies found that taking a walk in a forest is good for us in a number of ways: reduces stress, improves our mood, and good for our physical health (e.g., lowers blood pressure, benefits immune system). It shouldn't be a surprise that walking in nature is soothing.

A recent presentation at the American Psychiatry Association (APA) annual meeting discussed a review of 15 studies looking at the health benefits of walking in a forest. While the length of time varied in each study, it was generally 2 walks per week, 2 hours at a time. The health benefits were so clear that the researchers said such walks are therapeutic and could be viewed as forest therapy.

While most of us call it a walk in nature or a walk in the woods, the Japanese refer to it as shinrin yoku, which translates as forest bathing. They have long-recognized the health benefits of shinrin yoku, and doctors prescribe forest bathing to stressed people to "recharge and recover". Some doctors in the US also recommend prescribing walks in nature (nature prescribed) - Park Rx America

From Medscape: Growing Evidence for the Healing Power of ‘Forest Therapy’

Spending time in a forest — an experience known as Shinrin-Yoku, or “forest bathing,” in Japan where the practice originated — can lift mood, reduce stress, and promote physical health, a new literature review suggested.

Most of the studies included in the review reported moderate to strong effect sizes, using validated measures such as the Profile of Mood States (POMS) and physiological indicators like blood pressure. ...continue reading "A Walk In the Woods Is Good For Us"

Amazing how opinions regarding cannabis have changed in a few decades. From marijuana being viewed as an evil drug years ago to viewing cannabis (both marijuana and hemp) as medicinal and a pain reliever nowadays. A recent study suggests that regular use of cannabis (by either ingesting it orally via oil extracts or by smoking) can reduce blood pressure in older adults with hypertension.

The Ben-Gurion Univ. of the Negev (Israel) researchers found that after 3 months of medical cannabis use by 26 persons over 60 years of age, there was a reduction of both systolic and diastolic blood pressure numbers. The lowest blood pressure occurred 3 hours after ingesting or smoking cannabis.

Published on Leave a comment on Stretching Exercises Can Help Reduce Blood Pressure

An recent study from University of Saskatchewan researchers found that stretching exercises were better than brisk walking for lowering high-normal blood pressure or moderately elevated blood pressure. However, walking was more effective than stretching for reducing waist size.

The researchers randomly assigned 40 male and female adults (average age 61 years) with high normal or moderate hypertension (130/85–159/99 mm Hg) to either 8 weeks of whole body stretching exercises or brisk walking (on outdoor trails or a treadmill) for 30 minutes per day, 5 days a week, for 8 weeks. The stretching exercise routine included 21 exercises for the shoulders, chest, legs, arms, hips, and back. Each stretch was done twice and held for a 30-second duration with 15 seconds of rest between stretches.

Other studies have also found stretching exercises effective in reducing blood pressure. A possible reason is that when muscles are stretched, blood vessels are also stretched, and this may lead to structural changes in blood vessels. By reducing arterial stiffness, there is improved blood flow, and ultimately reduced blood pressure.

The researchers suggested adding stretching exercises to an aerobic exercise program or brisk walking for additional health benefits. By the way, stretching exercises are similar to yoga, which also lowers blood pressure.

Published on Leave a comment on Dairy Products, Hypertension, Diabetes, and Metabolic Syndrome

For several years I've noticed studies that show beneficial health effects from consumption of dairy products, especially whole milk or full-fat products, and also fermented dairy products (e.g. yogurt, cheese). A recent international study (21 countries on 5 continents) found similar results: higher intake of dairy foods, especially full-fat dairy, is associated with lower incidence of type 2 diabetes, high blood pressure (hypertension), and metabolic syndrome.

Metabolic syndrome is a group of conditions that increases the risk of heart disease, stroke, type 2 diabetes, and early death. Risk factors include increased blood pressure, excess body fat around the waist, elevated triglycerides and cholesterol levels, and elevated blood glucose.  Diet plays a role in whether one develops metabolic syndrome and diabetes. [Being overweight and being inactive are also important risk factors.]

What was the higher intake of dairy products that was associated with health benefits? At least 2 servings per day. The study did not look into what kind of dairy people drank and ate - whether cow, sheep, camel, or goat milk dairy. The assumption is: dairy is dairy!

While it was an observational study, it was significant, especially because the 131,481 participants (aged 35 to 70 years) were from world regions not typically studied in dairy consumption studies. They were tracked for about 9 years.

Excerpts from Science Daily: Dairy-rich diet linked to lower risks of diabetes and high blood pressure

Eating at least two daily servings of dairy is linked to lower risks of diabetes and high blood pressure, as well as the cluster of factors that heighten cardiovascular disease risk (metabolic syndrome), finds a large international study published online in BMJ Open Diabetes Research & Care.  ...continue reading "Dairy Products, Hypertension, Diabetes, and Metabolic Syndrome"

Published on Leave a comment on Improve Health and Lose Weight By Restricting Eating To A 10 Hour Window

Another great option for losing weight and better health may be to only eat within a 10 hour window, and then not eat for 14 hours (thus a nightly 14 hour fast). Many may find this easier than traditional dieting (counting calories and restricting eating). Just eat breakfast later, supper earlier, and no snacks in the evening. (But water is OK.)

Researchers from the Univ. Of California and Salk Institute conducted the 10-hour restricted eating study on persons with metabolic syndrome, most of whom were also on high blood pressure (anti-hypertensive) medicine and statins. After 12 weeks the people had lost weight, lost body fat, lowered blood pressure, reduced cholesterol, and decreased the size of their waist.

Since metabolic syndrome raises the risk for diabetes and heart (cardiovascular) disease, then 10-hour restricted eating can be an important tool to improve health. The researchers point out that in animal studies, time-restricted feeding can prevent and reverse aspects of metabolic diseases, and in healthy humans, it reduces the risks of metabolic diseases. Studies also found benefits with 9-hour restricted eating and 12 hour fasts.

Published on Leave a comment on Add Cherries To Your Diet

Another study finds beneficial health effects from eating real foods - this time eating Montmorency tart cherries reduces blood pressure and insulin levels up to 5 hours after ingestion. Of course. It was a small study done in the United Kingdom, with only 11 middle-aged participants, all with metabolic syndrome (increased blood pressure, high blood sugar, excess body fat around the waist, and abnormal cholesterol or triglyceride levels). It is estimated that about a third of U.S. adults have metabolic syndrome, which significantly increases the risk of cardiovascular disease and type 2 diabetes.

It was a nicely designed study, and the Montmorency tart cherries were taken in either juice form or capsules which contained freeze-dried Montmorency tart cherry powder. Drinking the juice had slightly better health effects than the freeze dried capsules. It would have been nice if they had also looked at a group of people eating fresh Montmorency tart cherries, rather than just juice or freeze dried cherries.

Keep in mind that this study found positive health effects from real food. However, in contrast, studies find that taking supplements and vitamins generally don't result in health benefits (e.g. calcium, omega-3, niacin, antioxidants), and can even cause harm - unless one has a nutritional deficiency. Studies also don't find that there are "superfoods" - instead, what is beneficial or not is the overall dietary pattern. Studies show that a diet rich in fruits, vegetables, whole grains, nuts, seeds, and legumes has many health benefits (something along the line of the Mediterranean dietary pattern). Try to eat a variety of fruits and vegetables - each has different micronutrients, and even different microbes (good!). Eating that way also results in a high fiber intake, which has many health benefits.

Published on Leave a comment on Blueberries and Blood Pressure

Once again a study finds that eating berries (this time blueberries) is associated with health benefits - that the blueberries improved both blood vessel functioning and blood pressure. This multi-part European study was conducted on both humans and mice. The researchers specifically looked at what component of blueberries had the beneficial effects on blood pressure and came to the conclusion that it was the anthocyanins in the blueberries.  Anthocyanins are the blue, violet, or red flavonoid pigments found in berries and other plants.

How much did the researchers find to be beneficial in the study? 2 cups or 200 g blueberries daily for one month. The study participants drank blueberry juice, but the assumption is that eating whole blueberries has the same beneficial effect.The researchers found that the lowering of blood pressure (5 mmHg) is similar to what is commonly observed with blood pressure lowering medication (e.g. ACE inhibitors) in patients.

By the way, research finds health benefits from eating a variety of berry types and richly colored fruits and vegetables (e.g. better brain functioning, lower blood pressure, lowering of cholesterol levels). Not only are the micronutrients different, but also the microbial species which we ingest (this is good!). So don't eat just one kind of berry - eat them all!
