A simple solution to a longer life!

A dietary swap that could lengthen your life?

Swapping butter for plant-based oils could trim your risk of early death by 17%, according to a new study.

“Even cutting back butter a little and incorporating more plant-based oils into your daily diet can have meaningful long-term health benefits.” 
-Daniel Wang, Brigham and Women’s

A study from Mass General Brigham, Harvard T.H. Chan School of Public Health, and the Broad Institute found that replacing butter with plant-based oils like soybean, canola, and olive oil could reduce the risk of premature death by up to 17%. Analyzing data from over 200,000 participants tracked for 30+ years, the research showed that higher butter consumption was linked to a 15% increased risk of death, particularly from cancer and cardiovascular disease, while greater use of plant-based oils was associated with a 16% lower risk. Published in JAMA Internal Medicine, the study highlights that swapping just 10 grams of butter daily with plant oils could significantly cut cancer and overall mortality. The findings suggest a simple dietary shift could yield major public health benefits, though the study’s focus on health professionals may limit its generalizability. Future research will explore the biological reasons behind these effects.

In addition to Zhang and Wang, Mass General Brigham authors include Katia S. Chadaideh, Yuhan Li, Yuxi Liu, Eric B. Rimm, Frank B. Hu, Walter C. Willett, and Meir J. Stampfer. Additional authors include Yanping Li, Xiao Gu, and Marta Guasch-Ferré.

This study was supported by research grants from the National Institutes of Health.

Fathers Are Happier Than Mothers, Study Shows — And Here's Why

The third study compared fathers to mothers and their level of happiness while caring for their children. Fathers, it seems, are more likely to be happy while caring for their children than mothers. A 2019 study out of the University of California Riverside, highlights one more aspect in the divide between fathers and mothers, and more broadly, men and women. The research, a meta-analysis of three different studies, looked at the emotional health of 18,000 people and compared traits like well-being, happiness, episodes of depression, and stress. The first two studies within the research compared parents to childless people and found that fathers are happier than their child-free peers. The reason? Dads, more often than moms, report playing with their children while providing care. Now, let's unpack this a bit. We can assume, that of the 18,000 couples who took part in this research, many split household chores equally. But over recent years, much light has...

Your friends shape your microbiome — and so do their friends

Analysis of nearly 2,000 people living in remote villages in Honduras reveals who’s spreading gut microorganisms to whom. Friends share more than just food when they dine together.Credit: Getty A shared meal, a kiss on the cheek: these social acts bring people together — and bring their microbiomes together, too. The more people interact, the more similar the make-up of their gut microorganisms is, even if individuals don’t live in the same household, a study1 shows. The study also found that a person’s microbiome is shaped not only by their social contacts but also by the social contacts’ connections. The work is one of several studies2 that raise the possibility that health conditions can be shaped by the transmission of the microbiome between individuals, not just by diet and other environmental factors that affect gut flora. In the quest to understand what shapes a person’s microbiome, social interactions are “definitely a piece of the puzzle that I think has been missing until rec...

What would it be like if your neurons could regenerate?

  What If Neurons Could Regenerate? Imagine a world where your brain could heal and renew itself like your skin or liver. How would that change your life? Would you still be the same person, or would you evolve into someone entirely different? Let’s dive into this mind-bending idea together. The top image shows fluorescently labeled cells in the spinal cord of a zebrafish recovering one week after an injury, and the bottom image shows recovery four weeks after an injury. Researchers at Washington University School of Medicine in St. Louis describe the dramatic changes within nerve cells that make regeneration possible. Such findings could inspire the development of new therapies for spinal cord injuries in people.

Learning could become faster and more efficient, making knowledge ret...
