Finding a fiber of good moral fiber

If you’ve ever wandered into the supplement aisle at your local grocery store, you’ve probably noticed an overabundance of fiber supplements that claim to do this for you and benefit that. Since there’s no Food and Drug Administration regulation on fiber supplements, manufacturers are free to (and do) make whatever wild claims they like. And much like choosing which of 500 shows to watch on Netflix, when you’re spoiled for choice, it can be difficult to pick.

fiber_supplements_web.jpg

Enter a team of molecular geneticists and microbiologists from Duke University. They can’t tell you what show to watch next, but they can tell you which fiber to choose, thanks to their new study. And the answer? Yes.

Well that’s not very helpful, but let us explain. For their study, a group of 28 received three of the main fiber supplements (inulin, dextrin, and galactooligosaccharides) for a week each, followed by a week off of fibers for their gut to return to baseline until they’d received all three. Those who consumed the least fiber at baseline saw the greatest benefit from fiber supplementation, with no appreciable difference between the three types. It was the same story for study participants who already consumed enough fiber; because their guts already hosted a more-optimal microbiome, the type of supplement didn’t matter. The benefits were the same across the board.

In an additional study, the Duke researchers found that gut microbiomes reacted to new fiber within a day, being primed to consume fiber on the first dose and digesting it more quickly on the second fiber dose.

The results, the researchers pointed out, make sense, since the average American only consumes 20%-40% of their daily recommended supply of fiber. Our digestive systems aren’t picky; they just want more, so go out there and choose whatever fiber you’d like. Do that, and then feel free to eat as many double bacon cheeseburgers as you’d like. That is the pinnacle of diet right there. Dietitians literally could not complain about it.
 

Jarlsberg vs. Camembert: This time it’s skeletal

Fiber is fabulous, of course, but the road to dietary health and wellness fulfillment takes us to many other, equally wondrous places. Hey, look! This next exit is covered with cheese.

jarlsberg_cheese_web.jpg

All the cheeses are here, from Abbaye de Belloc to Zwitser, and there, right between the jalapeno cheddar and the Jermi tortes you’ll find Jarlsberg, a mild, semisoft, nutty-flavored cheese that comes from Jarlsberg in eastern Norway. A recent study also suggests that Jarlsberg may help to prevent osteopenia and osteoporosis.

A group of Norwegian investigators gathered together 66 healthy women and gave them a daily portion of either Jarlsberg or Camembert for 6 weeks, at which point the Camembert group was switched to Jarlsberg for another 6 weeks.

The research team choose Camembert because of its similarity to Jarlsberg in fat and protein content. Jarlsberg, however, also is rich in vitamin K2, which is important for bone health, and a substance known as DHNA, which “might combat bone thinning and increase bone tissue formation,” they said in a Eurekalert release.

After the first 6 weeks, blood levels of osteocalcin; vitamin K2; and PINP, a peptide involved in bone turnover, were significantly higher in the Jarlsberg group only. All those measures rose significantly after the switch from Camembert to Jarlsberg, while levels of total and LDL cholesterol “fell significantly in the Camembert group after they switched to Jarlsberg,” the team added.

But wait! There’s more! HbA1c fell significantly among those initially eating the Jarlsberg but rose sharply in those eating Camembert. Do you see where this is going? After the Camembert group made the switch to Jarlsberg, their HbA1c levels fell significantly as well.

So it’s not just a cheese thing: The effects are specific to Jarlsberg. Can you guess what we’re having for lunch? Double bacon and fiber Jarlsbergers. Mmm, Jarlsburgers.
 

 

 

Luck be a lady: The mother of twins

It’s widely believed that women who have twins must be more fertile, giving birth to more than one child at a time. Some studies have supported the idea, but more recent work is refuting that claim. In actuality, it might just be more statistics and luck than fertility after all.

Those earlier studies supporting fertility didn’t specify whether the chances of twin births were based on the ability to produce more than one egg at a time or on the number of births that women had overall. Looking at 100,000 preindustrial European births, before contraception was available, researchers from Norway, Germany, France, and the United Kingdom found that the number of total births, twins included, makes all the difference.

“When a woman gives birth several times, the chances increase that at least one of these births will be a twin birth,” investigator Gine Roll Skjærvø of the Norwegian University of Science and Technology said in a written statement.

Since twins occur in 1%-3% of all births, the more births that a woman has, the better her chances of giving birth to twins. The researchers compared it to playing the lottery. You buy enough tickets, eventually your numbers are going to come up. Despite that, however, they found that women who give birth to twins give birth less often than those who don’t have twins. Which raises the idea of sheer luck.

The researchers said that there’s still a lot to uncover in twin births, noting that “uncritically comparing groups of women with and without twins can trick us into believing the opposite of what is really true. These groupings may either hide the effects of twinning and fertility genes where they exist, or vice versa, create the illusion of these if they do not exist.”

For now, this new research claims that it’s basically a lottery. And women who give birth to twins hit the jackpot.
 

Those with low wages may be earning future memory loss

Not only are low wages detrimental to our souls, hopes, and dreams, but a new study shows that low wages also are linked to quicker memory decline later in life. Sustained low wages not only cause stress and food insecurity in the lives of many, but they also can cause diseases such as depression, obesity, and high blood pressure, which are risk factors for cognitive aging.

wallet_empty_web.jpg

The study was conducted using records from the Health and Retirement Study for the years 1992-2016 and focused on 2,879 adults born between 1936 and 1941. The participants were divided into three groups: those who never earned low wages, those who sometimes did, and those who always did.

The investigators found that workers who earned sustained low wages – defined as an hourly wage lower than two-thirds of the federal median wage for the corresponding year – “experienced significantly faster memory decline in older age” than did those who never earned low wages.

There are signs of inflation everywhere we look these days, but many people are not earning higher wages to compensate for the extra expenses. “Increasing the federal minimum wage, for example to $15 per hour, remains a gridlock issue in Congress,” lead author Katrina Kezios of the Columbia University Mailman School of Public Health, said in a statement released by the university.

If only salaries would rise instead of prices for once.

This next exit is covered with cheese.</p> <p>[[{"fid":"288527","view_mode":"medstat_image_flush_right","fields":{"format":"medstat_image_flush_right","field_file_image_alt_text[und][0][value]":"wedge of Jarlsburg cheese","field_file_image_credit[und][0][value]":"PxHere","field_file_image_caption[und][0][value]":""},"type":"media","attributes":{"class":"media-element file-medstat_image_flush_right"}}]]All the cheeses are here, from <span class="Hyperlink"><a href="https://www.cheese.com/abbaye-de-belloc/">Abbaye de Belloc</a></span> to <span class="Hyperlink"><a href="https://www.cheese.com/zwitser/">Zwitser</a></span>, and there, right between the jalapeno cheddar and the <span class="Hyperlink"><a href="https://www.cheese.com/jermi-tortes/">Jermi tortes</a></span> you’ll find Jarlsberg, a mild, semisoft, nutty-flavored cheese that comes from Jarlsberg in eastern Norway. A <span class="Hyperlink"><a href="https://nutrition.bmj.com/content/early/2022/06/29/bmjnph-2022-000424">recent study</a></span> also suggests that Jarlsberg may help to prevent osteopenia and osteoporosis.<br/><br/>A group of Norwegian investigators gathered together 66 healthy women and gave them a daily portion of either Jarlsberg or Camembert for 6 weeks, at which point the Camembert group was switched to Jarlsberg for another 6 weeks.<br/><br/>The research team choose Camembert because of its similarity to Jarlsberg in fat and protein content. Jarlsberg, however, also is rich in vitamin K<sub>2, which is important for bone health,</sub> and a substance known as DHNA, which “might combat bone thinning and increase bone tissue formation,” they <span class="Hyperlink"><a href="https://www.eurekalert.org/news-releases/960329">said in a Eurekalert release</a></span>.<br/><br/>After the first 6 weeks, blood levels of osteocalcin; vitamin K<sub>2; and </sub>PINP, a peptide involved in bone turnover, were significantly higher in the Jarlsberg group only. All those measures rose significantly after the switch from Camembert to Jarlsberg, while levels of total and LDL cholesterol “fell significantly in the Camembert group after they switched to Jarlsberg,” the team added.<br/><br/>But wait! There’s more! HbA1c fell significantly among those initially eating the Jarlsberg but rose sharply in those eating Camembert. Do you see where this is going? After the Camembert group made the switch to Jarlsberg, their HbA1c levels fell significantly as well.<br/><br/>So it’s not just a cheese thing: The effects are specific to Jarlsberg. Can you guess what we’re having for lunch? Double bacon and fiber Jarlsbergers. Mmm, Jarlsburgers.<br/><br/></p> <h2>Luck be a lady: The mother of twins</h2> <p>It’s widely believed that women who have twins must be more fertile, giving birth to more than one child at a time. Some studies have supported the idea, but <span class="Hyperlink"><a href="https://www.nature.com/articles/s41467-022-30366-9">more recent work</a></span> is refuting that claim. In actuality, it might just be more statistics and luck than fertility after all. </p> <p>[[{"fid":"288529","view_mode":"medstat_image_flush_right","fields":{"format":"medstat_image_flush_right","field_file_image_alt_text[und][0][value]":"twins","field_file_image_credit[und][0][value]":"Michael Blackburn/istockphoto","field_file_image_caption[und][0][value]":""},"type":"media","attributes":{"class":"media-element file-medstat_image_flush_right"}}]]Those earlier studies supporting fertility didn’t specify whether the chances of twin births were based on the ability to produce more than one egg at a time or on the number of births that women had overall. Looking at 100,000 preindustrial European births, before contraception was available, researchers from Norway, Germany, France, and the United Kingdom found that the number of total births, twins included, makes all the difference. <br/><br/>“When a woman gives birth several times, the chances increase that at least one of these births will be a twin birth,” investigator Gine Roll Skjærvø of the Norwegian University of Science and Technology said in <span class="Hyperlink"><a href="https://www.eurekalert.org/news-releases/960556">a written statement</a></span>.<br/><br/>Since twins occur in 1%-3% of all births, the more births that a woman has, the better her chances of giving birth to twins. The researchers compared it to playing the lottery. You buy enough tickets, eventually your numbers are going to come up. Despite that, however, they found that women who give birth to twins give birth less often than those who don’t have twins. Which raises the idea of sheer luck. <br/><br/>The researchers said that there’s still a lot to uncover in twin births, noting that “uncritically comparing groups of women with and without twins can trick us into believing the opposite of what is really true. These groupings may either hide the effects of twinning and fertility genes where they exist, or vice versa, create the illusion of these if they do not exist.”<br/><br/>For now, this new research claims that it’s basically a lottery. And women who give birth to twins hit the jackpot. <br/><br/></p> <h2>Those with low wages may be earning future memory loss</h2> <p>Not only are low wages detrimental to our souls, hopes, and dreams, but a new study shows that low wages also are linked to quicker memory decline later in life. Sustained low wages not only cause stress and food insecurity in the lives of many, but they also can cause diseases such as depression, obesity, and high blood pressure, which are risk factors for cognitive aging.</p> <p>[[{"fid":"288528","view_mode":"medstat_image_flush_left","fields":{"format":"medstat_image_flush_left","field_file_image_alt_text[und][0][value]":"empty wallet","field_file_image_credit[und][0][value]":"Nicola Barts/Pexels","field_file_image_caption[und][0][value]":""},"type":"media","attributes":{"class":"media-element file-medstat_image_flush_left"}}]]The study was conducted using records from the <span class="Hyperlink"><a href="https://hrs.isr.umich.edu/about">Health and Retirement Study</a></span> for the years 1992-2016 and focused on 2,879 adults born between 1936 and 1941. The participants were divided into three groups: those who never earned low wages, those who sometimes did, and those who always did. <br/><br/>The investigators found that workers who earned sustained low wages – defined as an hourly wage lower than two-thirds of the federal median wage for the corresponding year – “experienced significantly faster memory decline in older age” than did those who never earned low wages.<br/><br/>There are signs of inflation everywhere we look these days, but many people are not earning higher wages to compensate for the extra expenses. “Increasing the federal minimum wage, for example to $15 per hour, remains a gridlock issue in Congress,” lead author Katrina Kezios of the Columbia University Mailman School of Public Health, <span class="Hyperlink"><a href="https://www.publichealth.columbia.edu/public-health-now/news/persistent-low-wages-linked-faster-memory-decline-later-life">said in a statement</a></span> released by the university. <br/><br/>If only salaries would rise instead of prices for once.<span class="end"/></p> </itemContent> </newsItem> <newsItem> <itemMeta> <itemRole>teaser</itemRole> <itemClass>text</itemClass> <title/> <deck/> </itemMeta> <itemContent> </itemContent> </newsItem> </itemSet></root>
