There is tremendous interest in how to live a long and healthy life. This means trying to avoid getting diseases that so many suffer from as they age, such as diabetes, heart disease, and dementia. What diets are best? What kind of lifestyle?

NPR published a recent article about 7 daily habits linked to living a longer, healthier life, using information from Dan Buettner's work on blue zones. Scientific research supports the importance of these habits, especially good nutrition (for example, the Mediterranean diet) and physical activity.

The blue zones are communities throughout the world in which there are a lot of centenarians (people living to 100 years or more). What is important is that the people in these communities are aging with good health, and leading active and fulfilling lives - without dementia, and not in nursing homes.

The diets vary from place to place, but all avoid fast foods and highly processed foods. Instead, a lot of vegetables, fruits, whole grains, legumes (beans), and nuts are eaten. Little meat. Food is cooked at home. By the way, this type of diet is associated with a good gut microbiome, and generally a good gut microbiome goes with good health.

Unfortunately, these blue zone areas are now fading, due to changes in lifestyles  - fast food, etc. But a few other places are stepping up, trying to make living spaces healthier and incorporating what has been learned about health and longevity - for example, Singapore.

Bottom line: Research shows a diet rich in plant-based foods (whole grains, fruits, vegetables, nuts, seeds, legumes), plenty of sleep, lots of movement (physical activity), and a sense of purpose in life are all important in aging well.

Excerpts from correspondent Allison Aubrey article at NPR: 7 habits to live a healthier life, inspired by the world's longest-lived communities

At a time when life expectancy in the U.S. has dipped and diet-related disease is a leading cause of death, it's no wonder that Dan Buettner's decades-long exploration of centenarians who thrive in the longest-lived communities on Earth is attracting lots of attention. ...continue reading "Some Habits For Living A Longer and Healthier Life"

There has been tremendous interest in the past decade over the best diet and lifestyle for aging well and living to a ripe old age. Author Dan Buettner has spent much of the past decade visiting communities around the world where there are many residents who live to 100 years or more, and in good health. He calls these communities blue zones.

Dan Buettner now has a good National Geographic documentary on Netflix called Live to 100: Secrets of the Blue Zones. This documents him visiting Blue Zones (Ikaria, Greece; Okinawa, Japan; Sardinia, Italy; Loma Linda, Calif.; and Nicoya Peninsula, Costa Rica) looking at the lifestyles and diets in this communities.

He found that while the diets vary, overall the people in these communities have a lot of plant based whole foods (especially whole grains, vegetables, beans, and tubers, such as sweet potatoes), and they avoid fast-food and highly processed foods. They do not take dietary supplements. They have a lot of physical activity in their daily activities, are committed to their families, take time to de-stress, and they have social networks with healthy behaviors.

He also recently published a book called The Blue Zones Secrets for Living Longer: Lessons From the Healthiest Places On Earth.

Congenital syphilis rates are rising in the United States. This is when a pregnant woman has syphilis and transmits it to the developing baby (fetus). It results in serious long-term problems for the baby (e.g., stillbirth, deformities, neurological problems, hearing loss) .

Syphilis is an infection caused by the bacterium Treponema pallidum that is treated with antibiotics. Thus congenital syphilis is totally preventable. This is why it is important to do screening and treating for syphilis early in pregnancy.

A study looking at congenital syphilis cases in Mississippi found that cases occur when a pregnant woman doesn't get screened during pregnancy for syphilis, or doesn't receive proper prenatal care. Another risk factor is drug use by the mother. The mother should be screened for syphilis in early pregnancy, and then treated with antibiotics if syphilis is found.

Some states have had a bigger increase than others, especially southwestern and southern states such as Mississippi. It is one of the states that did not require  screening for syphilis in pregnancy, which only became a requirement in Mississippi starting March 2023.

From Medical Xpress: Congenital syphilis rates are soaring, but resources to stem infections are lacking

States are seeing an alarming surge in cases of congenital syphilis, a preventable infection that can lead to miscarriage, stillbirth, newborn death—or lifelong complications such as blindness or deafness. ...continue reading "Testing For Syphilis Is Important During Pregnancy"

A recent small study discussed the issue of postpartum depression in new fathers, and whether all fathers of newborns should be screened for it. Most people know that women can develop postpartum depression, but the possibility that fathers can also have it is rarely discussed.

In this small study conducted in Chicago, they found that 30% of the 24 fathers appeared to have postpartum depression - based on the same screening tool that is commonly used to screen new mothers. Other studies found/estimated that 8 to 13% of new fathers have postpartum depression, but with much higher rates if the new mother has postpartum depression.

Yes - new fathers can be stressed, anxious, worried, depressed, especially if there are financial or other stressors. Lack of sleep and fatigue was a big contributor to symptoms in the study. Pre-existing mental conditions. Problems with the relationship. Lack of paid parental leave. And on and on.

Both new mothers and new fathers need support after the birth of a baby.

From Science Daily: Should fathers be screened for postpartum depression? Pilot study

Dads can suffer from postpartum depression, and a new pilot study at the University of Illinois Chicago suggests they can and should be screened for the condition. Given the intertwined effects of mothers' and fathers' physical and mental health, addressing the health of fathers may be a powerful untapped tool in improving the nation's ongoing maternal health crisis. ...continue reading "Postpartum Depression In New Fathers"

Buyer beware when it comes to lawn care services. Lately I've been seeing a number of lawn care companies saying they offer "organic-based" or "organic  weed-free lawn care" or "natural lawn care". Nope, nope, nope.

These companies do NOT provide organic lawn care. Instead it's the same old routine of using toxic pesticides disguised with organic, environmentally friendly buzzwords. And yes, these pesticides are harmful to adults, children, pets, wildlife, birds, bees, butterflies, and the environment.

How do you you know that they are not providing organic lawn care?

1) One big tip off is "weed free" lawns. Nope. A real organic lawn has diversity of plants - for example, clover.  Only toxic pesticides can give you the sterile carpet look. Yes, an organic lawn can be lush, beautiful, and green, but it's different than a sterile carpet with only 1 species of grass (a monoculture).

2) Another warning sign is that they routinely apply "preemergent herbicides" (weed-killers). Nope, nope, nope. For example, one popular herbicide used by such companies is 2,4,-D. This was one of the 2 pesticides used in Agent Orange, and yes - it sticks around. Yikes!

3) They use the word "organic-based". They generally use this only when discussing fertilizers. Hah! Talk is cheap. I haven't yet seen evidence of real organic fertilizers being used.

4) They will routinely schedule "insect control" - of course, by using toxic pesticides. If they were real organic, they wouldn't do that - it wouldn't be needed and/or desired.

By the way, pyrethroids are synthetic toxic pesticides - they are NOT from chrysanthemums and have different effects, such as being toxic to bees and butterflies, and with harmful effects on humans, especially children. They are not used in real organic lawn care. ...continue reading "Buyer Beware When It Comes to “Organic-Based” Lawn Care Services"

A recent large study found another great reason for being physically active. The researchers found that physical fitness is linked to  atrial fibrillation (AFib) and stroke.

Atrial fibrillation is a heart rhythm disorder, and having it is linked to a much higher risk of having a stroke. The researchers found that being physically fit (exercise! physical activity!) is linked to lower rates of atrial fibrillation, stroke, and MACE (major adverse cardiovascular events, such as stroke or heart attack leading to death).

There was an eleven year follow up of the approximately 15,450 participants, all of whom did not have atrial fibrillation at the start of the study. The study tested the  physical fitness of the participants (average age 55 years) on an exercise treadmill.

Bottom line: Physical activity and physical fitness are important for reducing the risk of developing heart problems, including atrial fibrillation. Yes, even taking walks (brisk is best) will improve physical fitness.

From Science Daily: Keep fit to avoid heart rhythm disorder and stroke

A study in more than 15,000 people has found that physical fitness is linked with a lower likelihood of developing atrial fibrillation and stroke. The research is presented at ESC Congress 2023.

Do you know what chemicals you're exposed to on a daily basis? A recent study found that women with cancers of the breast, uterus, skin (melanoma), or ovaries had significantly higher levels of certain endocrine disrupting chemicals in their bodies than women without any of those cancers.

The researchers looked at levels of some hormone disrupting chemicals: PFAS (per- and polyfluoroalkyl substances), phenols (e.g. BPA), and parabens in both men and women. They found that women had higher levels of endocrine disruptors for 4 types of cancers (breast, uterine, ovarian, and melanoma). However, there was no relationship between the endocrine disruptors and thyroid cancer in men or women, and no relationship in men with prostate cancer.

The reason the researchers looked at breast, prostate, thyroid, ovarian, endometrial, and testicular cancers, and melanoma is because they are "hormone-mediated" cancers. That is, hormones play a role in growth and progression of these cancers.

Bottom line: You cannot totally avoid these chemicals because they are used in so many products, but you can really lower your exposure to them. Read Avoiding Harmful Chemicals for easy tips on reducing your exposure to these harmful chemicals. For example, don't use non-stick pots and pans, don't use plug-in air fresheners, and try to use fragrance-free or unscented products as much as possible. Use paraben and phthalate-free personal care products.

From Medical Xpress: Study finds significant chemical exposures in women with cancer

In a sign that exposure to certain endocrine-disrupting chemicals may be playing a role in cancers of the breast, ovary, skin and uterus, researchers have found that people who developed those cancers have significantly higher levels of these chemicals in their bodies. ...continue reading "Some Cancers In Women Linked to Chemical Exposures"

This site spends a lot of time discussing the nasal passages and sinuses. That's why a study focusing on the average number of hairs in the nose drew my attention.

The study won a 2023 Ig Nobel Award in medicine. The Ig Awards are basically a good-natured parody of Nobel prizes, where studies that at first seem silly, but then make you think, win awards.

The University of California researchers used 20 cadavers (10 male and 10 female dead persons) to study whether a person has the same number of hairs in both nostrils.

They carefully counted the number of hairs in each nostril and found that people generally have between 120 and 122 hairs per nostril. [The article is behind a paywall, so I searched and found that one mention of the study said on average there were 120 nose hairs on the left side and 112 on the right side.]

Another finding: the hair grows in the front of the nostril and only grows to a height of 0.81 to 1.035 centimeters.

Great news! A good chemical-free way to prevent mosquitoes from bothering you when sitting outside is to just set up a fan nearby and turn it on. Mosquitos are weak flyers and this will keep them away.

The head guy in the fight against mosquitos and West Nile Virus in NYC (Dr. Bajwa, a medical entomologist) turns on a pedestal fan when sitting outside his home. No chemicals needed!

Bottom line: Using a fan can ward off mosquitoes. People differ in the types of fans they like to use (oscillating fan, stationary fan, ceiling fan). By the way, a breezy or windy day is also great in keeping mosquitos away.

He has his own method of dealing with mosquitoes. “When I find myself relaxing in my backyard, I always set up a pedestal fan,” he wrote. “Mosquitoes happen to be weak fliers, unable to contend with even a gentle breeze.” When he does get bitten, he added, “I make a conscious effort not to give in to the temptation of scratching.”

The NY Times wrote about this method already back in 2010: The Claim: To Repel Mosquitoes, Use a House Fan ...continue reading "Wind From A Fan Can Keep Mosquitoes Away"
