Published on Leave a comment on Drinking Orange Juice Daily Has Health Benefits

Many of us drink a daily glass of orange juice thinking it is healthy for us and because it contains vitamin C. But is that true?

While some in the medical field view orange juice as basically orange-flavored sugar in a glass, others find orange juice to be a healthy beverage - one that is linked to a lower incidence of cardiovascular diseases.

A recent study found that there are numerous health benefits from drinking  orange juice daily. Regular consumption can influence the activity of thousands of genes in our immune cells - genes that help control blood pressure, improve inflammation, metabolism, and blood sugar control. Studies have also found improvements in cholesterol and blood vessel health - thus influencing long-term heart health.

How much orange juice to drink for health benefits? One cup of pure pasteurized orange juice daily should be sufficient. Note that in the study, adults drank 500 ml (2 cups) of pure pasteurized orange juice for 2 months. After 60 days, many genes associated with inflammation and higher blood pressure became less active.

Most of us think of orange juice as a simple breakfast habit, something you pour without much thought. Yet scientists are discovering that this everyday drink may be doing far more in the body than quenching thirst. ...continue reading "Drinking Orange Juice Daily Has Health Benefits"

Over the years, study after study has found a link between high whole-grain intake and a reduced risk of a number of chronic diseases, such as diabetes and heart disease. A recent review of studies also found that ....(drum roll)... eating a diet rich in whole grain foods is good for heart health and lowering chronic inflammation.

The review of 87 studies found that eating 4 to 6 servings of whole grain foods per day benefits heart health in a number of ways. The studies found that daily consumption of this amount of whole grain foods resulted in improvements in body weight, waist size, blood pressure, cholesterol, blood sugar, triglycerides, fasting glucose, insulin resistance, and some markers of inflammation.

There was a dose response effect - the more whole grains eaten, the better the health effects. Best health effects were from 4 to 6 servings daily (60 to 100 grams per day).

Bottom line: Whole grains have a number of health effects and can easily be added into the diet. Examples of whole grain foods: Oatmeal, barley, quinoa, wild rice, bulgur (cracked wheat), farro, millet, buckwheat, rye, spelt, brown rice, popcorn, whole wheat flour, whole grain breakfast cereals, and whole wheat bread and crackers.

By the way, 4 to 6 servings of whole grain foods per day is more than current US guidelines of 2 to 4 servings per day. But both agree that for health benefits need to eat "real whole foods" (not ultra-processed foods).

From Science Daily: Scientists find the whole grain “sweet spot” for better heart health

Eating four to six servings of whole grains each day may improve several major risk factors for cardiovascular disease, according to new research published September 15 in the European Heart Journal. ...continue reading "Eat More Whole Grain Foods For Heart Health"

Knee pain due to knee arthritis is something that many (most?) people complain about as they age. A recent study looking at what non-drug therapies helped people with knee pain found that some of the simplest treatments (knee braces, water-based therapy, exercise) worked best.

A review of 139 studies involving 9644 people and 12 therapeutic options (low level laser therapy, high intensity laser therapy, transcutaneous electrical nerve stimulation, interferential current, short wave diathermy, ultrasound, lateral wedged insole, knee brace, exercise, hydrotherapy (exercises done in warm water), kinesio taping and extracorporeal shock wave therapy) for knee arthritis was analyzed.

The researchers found that knee braces ranked highest overall for reducing pain, stiffness, and mobility problems. This was followed by water-based therapy was especially effective for pain, and regular exercise consistently improved both pain and physical movement. The high-tech approach of ultrasound was reported as the least effective, thus not recommended.

From Science Daily: Nearly 10,000 patients reveal what works best for knee arthritis pain relief

Knee braces, water therapy, and exercise may be among the most effective drug-free options for people with knee osteoarthritis, according to a large analysis published in the open-access journal PLOS One. The research was led by Yuan Luo of the First People's Hospital of Neijiang, China. ...continue reading "Simple Treatments May Work Best For Knee Arthritis Pain"

Published on Leave a comment on Are Statins Still Needed For Adults Over 75?

Many people are on statins these days for the purpose of lowering total cholesterol levels and so reducing the risk of heart attack and stroke. But are they still needed past a certain age?

The results of one study conducted in France compared 2 groups of adults 75 years old and older, and who didn't have a history of heart disease or stroke. One group stopped statins and the other continued statin use. They found that in the group of persons stopping statins there was no increase in death rates in the next 3 years, when compared with those still on statins.

There was no difference in heart attacks and strokes among the 2 groups. However, in the group that discontinued statins - their LDL cholesterol levels did rise.

Of course, there will be a lot of debate over these conclusions. And it is unknown if group differences will develop going forward, that is, in the next few years.

From Medical Xpress: Adults 75 and older who stopped statins had similar three-year survival, trial finds

Stopping statins in adults 75 and older with no history of heart disease or stroke does not increase the risk of death over three years compared with continuing statins, although "bad" cholesterol rose around 50% in those who stopped, according to a randomized controlled trial published in The Lancet Healthy Longevity.

Published on Leave a comment on California Is Finally Taking Steps To Ban A Highly Toxic Pesticide

For years it has been known that the pesticide paraquat has serious health effects, which is why it is banned in so many countries - but not the US. But California, the US's largest user of the toxic pesticide, is now the second state to ban the use of the pesticide. It is considered the deadliest pesticide used in agriculture in the US.

Paraquat is a herbicide (weed-killer) that is strongly linked to (causes) Parkinson's disease, and is known to damage the lungs, kidneys. liver, cardiac system, and other bodily systems. While it is banned in more than 70 countries world-wide (e.g., the EU, China, UK, Brazil), the EPA reapproved its use in 2024. More than 10 million pounds annually are sprayed on US crops (e.g., soybeans, almonds, walnuts, cotton), with the most used in California.

Once again, the US is lagging behind other countries in safety and health regulations. Unfortunately, the current EPA is led by persons affiliated with the chemical industry. No wonder it's big industry first in all decisions!

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.

From Science Daily: For decades, we were told to choose low-fat dairy. New research says otherwise

A new Canadian study led by University of Toronto professor Harvey Anderson adds to growing evidence that full-fat dairy can be part of a healthy diet. ...continue reading "Full-Fat Dairy Products Have Health Benefits"

For years sauna lovers have been praising the health benefits of hot sauna sessions, with studies finding reduced risk of hypertension, sudden cardiac death, stroke, dementia, and a lower risk of a number of respiratory conditions. A study from Finland suggests why these benefits from sauna sessions occur.

Researchers in Finland found that one 30 minute session of sauna heat increases beneficial immune effects by releasing more infection-fighting white blood cells into the bloodstream - an "immune cell mobilization". This effect is temporary.

The participants (51 healthy males and females, average age 50 years) in the study were exposed to traditional Finnish sauna sessions - with dry air and a relatively high temperature. The sessions lasted 30 minutes, with a brief cold shower midway during the session to cool down. They could drink water during and after the sauna sessions.

Physical activity also results in a similar temporary release of white blood cells. This is considered beneficial.

From Science Daily: A single sauna session sends immune cells surging

A new Finnish study suggests that spending time in a sauna can temporarily move more white blood cells into the bloodstream. These immune cells help the body detect and respond to pathogens and disease. ...continue reading "Sauna Sessions Boost Immune Cell Release Into Bloodstream"

Uh-oh. Things are looking worse and worse for male fertility. Studies already are finding that human sperm count is going down year after year throughout the world. But a recent study also found that testosterone levels are going down in men.

According to a study presented at the July 2026 meeting of the European Society of Human Reproduction and Embryology, testosterone levels in men have declined 54% between 1972 and 2019. This is a decline of more than 1% per year. Scientists are referring to this as a "major crisis in male reproductive health".

And no, the answer is not just giving men testosterone. As researchers have pointed out:  this suppresses or "cuts off sperm production".

Instead, it would be much, much better to address the causes of the drop in male sperm counts and lowered testosterone - for example, pesticides, endocrine disruptors (e.g., phthalates, bisphenols), heavy metals, microplastics, and pollution. These are all known to adversely affect male reproduction.

People have been arguing for years over what kinds of foods and dietary patterns are best for health, with many studies finding that a Mediterranean style diet is best for health.  Another recent study found that a Mediterranean-style diet rich in fruits, vegetables, nuts, legumes, whole grains, fish, and dairy is best for heart health when compared to other diets.

The study of 3042 Greek adults found that those following a plant-based style diet (basically a Mediterranean-style diet) had a 26% lower risk of developing heart disease over a 20 year period, when compared to either a Western diet rich in processed meat and ultra-processed foods, or to a high-calorie, but low-white-meat dietary pattern.

The high calorie, low white-meat diet seemed especially unhealthy. They also found that physical activity reduced heart disease (cardiovascular disease) risk, but smoking increased it.

Physical activity reduced CVD risk, while smoking increased it.

Excerpts from Medical News: Plant-based Mediterranean-style diet cuts heart disease risk by 26%

A recent European Journal of Nutrition study examined common dietary patterns in a Mediterranean cohort and assessed their long-term associations with cardiovascular disease (CVD) risk and outcomes.

A recent large study found that vitamin B3 (nicotinamide) supplements may help in preventing glaucoma (specifically primary open-angle glaucoma) and also need fewer treatments (e.g., eye drops and laser procedures) in those with glaucoma.

Glaucoma refers to many diseases involving eye pressure increases and damage to the optic nerve, which can result in permanent vision loss and blindness. Primary open-angle glaucoma (POAG) is the most common form of glaucoma. The study found that those taking nicotinamide supplements had a 66% lower risk of developing glaucoma.

Since the study is behind a paywall, I've included summaries (each a little different) from 2 web-sites describing the study.

From Medical Xpress: Could vitamin B3 prevent silent thief from stealing vision? New study finds protective effects against glaucoma

Often called the silent thief of sight, glaucoma is a group of eye diseases that gradually damage the optic nerve, often without warning signs. It is linked to increased pressure (ocular hypertension) inside the eye and, if left untreated, can lead to permanent vision loss. Even with ongoing treatment, some people still face the risk of progressive vision loss.

This led scientists to look for newer therapeutics that can help manage the disease's progression, such as nicotinamide, a form of vitamin B3. ...continue reading "Study Finds Vitamin B3 Supplements Lower the Risk of Developing Glaucoma"
