Diversify Your Gut Microbiome

5/26/2026

0 Comments

 
For as long as most can recall, the USDA has engrained the “5-A-Day” messaging into the psyche of Americans, that is, to eat five servings of fruit and vegetables a day. More recently, as microbiome science has evolved, researchers are espousing the benefits of diversity over quantity in our consumption of plant-based foods—meaning, we should focus on incorporating different types of plants rather than focusing on daily servings. To be clear at the outset of this blog, recommending a vegan or a vegetarian lifestyle is not where this is headed.
 
Let’s start at the beginning. In 2018, when the American Gut Project (AGP) published their research, more than 10,000 “citizen scientists” from the U.S., U.K. and Australia self-selected to contribute stool samples and details regarding their diet. Stool samples were analyzed for beta-diversity, or variation in microbes. Those who self-reported consuming the greatest dietary diversity of plants demonstrated the greatest diversity of microbial species, regardless of whether participants self-identified as a vegan or an omnivore.
 
Why is microbial diversity in the gut important? The gut microbiome (GMB) is the ecosystem of bacteria, fungi and viruses living mostly in the colon and, to a lesser degree, in the stomach and small intestine. The science evolves almost daily, but a dysbiotic or imbalanced GMB ecosystem has been linked to mental disorders, cardiometabolic diseases, immune dysfunction, neuroendocrine function and neurodegeneration. A more diverse gut ecosystem is thought to make a person more resilient to disease and aging.
 
The GMB is mutable, affected by certain lifestyle choices including but not limited to diet, exercise and stress. When it comes to diet, plant foods deliver a type of fiber known as prebiotics (food/energy for the microbes living in your GI tract) and antioxidants to your GI, which in turn develop a more resilient and diverse GMB. Thus, more plants = more diverse GMB = better health.
 
The publication of the AGP research led to several social media challenges to consume 30 different plant foods a week, the creation of the “Hack Your Health” documentary smoothie and the founding of ZOE, which conducts its own research on plant diversity and gut microbial diversity. (If you visit the ZOE site, you’ll find they sell several products and services. We are not suggesting these are necessary in order to participate in the challenge.)
 
The concept of the challenge is to eat 30 different types of plants per week. Once you have eaten one plant once that week, that’s it—you cannot count it again for that week!
 
What counts? Fruit, vegetables, nuts, seeds, spices, grains and herbs are all on the list, and even your coffee, tea, chocolate and extra virgin olive oil count! Juice does not count, because it has been stripped of its beneficial fiber.
 
Admittedly, this challenge will likely require a great deal of planning, shopping and prep work. Smoothies, soups and salads are your friends here! Even if you don’t hit the 30-plants-a-week goal, you can still benefit from the attempt. It’s always good to expand our horizons—you may even come to realize you had been stuck in a food rut eating the same foods over and over again.
 
If you decide to tackle this challenge, there are many apps, logs, books, etc., that you can purchase online to help guide you. We suggest keeping it simple out of the gate, and we have provided a printable PDF to help you log your progress. June’s Motivated Mondays’ mini resolution through CCP will be to eat more fruit and vegetables, so there will be plenty of creative recipes provided to help you try new recipes.

Steps to Better Health

3/23/2026

0 Comments

 
​Have you ever heard the notion that walking 10,000 steps a day leads to improved health outcomes? Well you may be surprised to learn that metric was developed for a marketing strategy in 1965 to sell a pedometer called Manpo-kei—translated to the “10,000 steps meter.”
 
Walking 10,000 steps is roughly equal to 5 miles and about 500 calories. But the original focus of tracking step counts was not to set exercise goals or lose weight. Rather, exercise scientists have studied step counts as a practical measure of sedentary behaviors.
 
Steps are a measure of how sedentary one is during the day outside of intentional exercise. In other words, step counts help to determine whether our Activities of Daily Living (ADLs) keep our body in motion or whether we sit for most of the day. Even if you intentionally exercise one hour a day, you are still considered sedentary if your steps are limited on average to about 2,700 steps a day. Likewise, if you jog 5 miles a day, i.e. 10,000 steps, but your step count outside that intentional activity is in the 2,700-step range, then you are still considered sedentary.
 
The Health Implications of an Increasingly Sedentary Society
 
Since the 1950s, rapid advances and changes in technology, communication, transportation and the workplace have evolved us into a society that spends much of the day sitting and less time being active. Being inactive, or taking fewer than 2,700 steps a day, has been linked to metabolic diseases, cardiovascular disease, dementia, depression, falls, sarcopenia, osteoporosis and cancer. It is now widely recognized that there is value in breaking up the time we spend sitting.
 
Science-Backed Goals with Encouraging Figures
 
Since the unofficial target of the 10,000-steps-a-day metric was an arbitrary number, what does science say is an ideal step count to counteract the effects of being sedentary?
 
Last summer a meta-analysis of 31 studies found that 7,000 steps a day vs. 2,000 steps is a clinically meaningful goal.
 
Importantly, researchers found this can lead to a 47% lower risk of all-cause and cardiovascular disease mortality, 25% lower risk of cardiovascular disease incidence, 37% lower risk of cancer mortality, 14% lower risk of diabetes, 38% lower risk of dementia, 22% lower risk of depressive symptoms, and a 28% lower risk of falls.
 
Finding Ways to Stay Active
 
After you have exercised with intention each day, what are some ways you can defy gravity and increase your ADL steps?
 
General Activities
  • Stand/walk around when speaking on the phone
  • Do your own housecleaning or gardening
  • Walk the dog the long way home (fun fact: dog owners have lower BP, cholesterol and triglycerides!)
  • Meeting a friend for coffee? Go for a stroll instead of sitting at a café.
  • Get off the couch at each commercial break (Even better? Lose the remote and get up to change the channel or volume—if your TV set still has those physical functions!)
  • Golfing? Skip the golfcart and walk the course
  • Go shopping in person instead of online
  • Plan some fun that involves walking such as visiting a museum, art gallery, flea market, street fair, etc.
 
Getting Around
  • Get off the bus or subway one stop earlier and walk to your destination from there
  • Walk errands
  • Take the stairs down, elevator up
  • Don’t use the drive-through window, park and walk inside
  • Park as far away from the store door as possible
 
At Work (if you are working in an office setting):
  • Use the printer/copier farthest from your desk
  • Set a timer to go off every 20 minutes to stand up and walk around
  • Get out of the office for at least 20 minutes each day to walk a few errands (this can be a great mental health break, too!)
 
And remember, what gets measured gets managed, so a small investment in a pedometer or fitness watch may be a worthwhile expense.
 
If your New Year’s resolution to start exercising with intention has fallen through, or if you already exercise with intention and want to stay motivated, Motivated Mondays, a member benefits through my partnership with Concierge Choice Physicians is about to embark on a two-month long resolution around exercise. If you aren’t already signed up, you may do so by clicking here.
 
And as always, we are here to help you achieve your wellness goals. Please reach out if you have any specific questions.

The Health Benefits of Love

2/4/2026

If you want to be alive, love is the truest health.
-Rumi

 
Over the past decade, researchers have used PET scans, MRIs and biomarkers to assess the neurobiology of love between romantic partners. In doing so, they’ve been able to get a closer look at the body’s chemical response to love and even explain such phenomena as “feeling weak in the knees,” or being “madly in love.” From the initial attraction to long-term marriage, the data demonstrates that being in a supportive, loving relationship offers several health benefits.
 
Do you know that feeling when just the thought of someone makes you weak in the knees? As it turns out, that feeling is not just in your head! Researchers have discovered that the initial throws of romance create a physiological stress response, including the release of a cascade of neurochemicals, most notably cortisol. This leaves our heart racing, induces sleepless nights and can lead to excitement and trembling at the thought of the person we admire. This biochemical response also leads to less fear, reduced depression and improved mood.
 
Moreover, owing to love-induced hypercortisolemia (a temporary rise in cortisol), serotonin is reduced, potentially leading to irrational behavior and lack of judgement particularly affecting our ability to critically assess our partner—a phenomena that leaves some feeling that “love is blind.”
 
And when we’re in love, our dopamine reward centers become activated (the same reward centers associated with addiction). This might leave us feeling indescribably infatuated with someone or, as some refer to it, “madly in love.”
 
As a romantic relationship endures, cortisol and adrenaline eventually level off. And as intimacy and emotional connection level up, something known as “pair bonding” occurs, wherein oxytocin (the “love” hormone), vasopressin (which regulate your kidneys) and GABA (the brain’s primary calming neurotransmitter) are released, leading to the relaxation response restoring the autonomic nervous system to homeostasis. This leads to a sense of calm, contentment and security as the heart rate, blood pressure and oxygen consumption are reduced. This stage also includes an upregulation of the immune system, improved mitochondrial efficiency, improved insulin secretion and reduced sensitivity to pain, i.e., love-induced analgesia.
 
Notably, the health benefits of love are sustained in long-term healthy relationships, specifically in those whom continue to describe themselves as “in love.” Sustaining that love through acts of kindness and displays of affection promotes a greater sense of purpose and well-being, further boost oxytocin, and lower blood pressure, leading to greater heart health and improved mood.
 
Importantly, the physiological benefits of love don’t just disappear when someone is not partnered. In fact, acts of self-love and displays of love for friends and family have many of the same life-sustaining benefits.
 
So this Valentine’s day (and every day), we encourage you to celebrate the love that sustains you, be it with a partner, with yourself, or in the nurturing relationships with friends and family.
