The interaction between your gut and your brain is really important. It’s called the gut-brain axis. Let’s start with an interview from March 2017 that aired on CBS This Morning. In this segment, they interviewed Dr. Rudy Tanzi, who is a PhD, Director of the Alzheimer’s Genome Project at Harvard Medical School and a researcher at Massachusetts General Hospital. In this interview, he discussed various steps you can take to reduce your risk of developing Alzheimer’s disease. The moderator of the interview asked Dr. Tanzi, “Aside from choosing the right parents, what can somebody do to prevent Alzheimer’s or try to help prevent Alzheimer’s?”

“The four big categories are diet, exercise, sleep, and stress reduction,” Dr. Tanzi said. “I wrote about this in my last book Super Genes. There’s 6 chapters, which is more than you wanted to know about how to adapt your diet to minimize inflammation and plaques, meaning Mediterranean diet and probiotics, take care of your gut bacteria.”

“Which probiotics?” the moderator asked. “Yogurt, a yogurt drink like kefir, or a probiotic pill with live bacteria,” Dr. Tanzi said.  The moderator goes on to ask, “Why would what’s going on in your gut affect what’s going on in your brain?”

“Well, so it turns out there’s what’s called a gut-brain axis,” Dr. Tanzi said. “When the bacteria in your gut are creating chemicals that interact with your brain, that do everything from determine your mood to control how much inflammation there is in your brain.”  

“And even obesity, right?” the moderator said. “It’s amazing what we’re learning about these trillions of bacteria that people were saying, ‘Oh, wash them out… I’m going to get a cleanse. They’re icky! Let’s get them out of us!’ It turns out, of course, millions of years of evolution — they’re there for a reason.”

“And you want to take care of them,” Dr. Tanzi said. “They’re there to help you. A Mediterranean diet, more fiber, more fruit, what are called prebiotics, probiotics…” You can read the remainder of this interview with Dr. Tanzi here.


Probiotic bacteria is very important as supplements. I always discuss rejuvenating your healthy bacteria through sleep, water, some exercise, and avoiding bad things like excessive alcohol. A good diet is extremely important as well. The fibers in your diet are the food for the bacteria in your gut. Fermented foods like kefir and good forms of yogurt like Greek yogurt and a probiotic supplement are also important for gut health.†     

Our gut is often referred to as our second brain. Our brain has a huge number of nerve cells and our gut does also. There are nerves directly connecting our gut to our brain. Expressions like “a gut feeling” or “butterflies in my stomach” refer to this connection going from the brain to the digestive tract. This connection also goes in the other direction. There is also communication that comes from the gut and affects the brain. A lot of this has to do with the trillions of bacteria, literally pounds of them, that reside in our digestive tract.†

The famous and highly entertaining astrophysicist Neil deGrasse Tyson wrote in his book Astrophysics for People in a Hurry that “more bacteria live and work in one centimeter of my colon than the number of people who have ever existed in the world. That kind of information makes you think twice about who – or what – is actually in charge.” It just makes sense and science proves that intestinal bacteria must interact in ways that impact many facets of our health, including our brain health and our brain function.†


Bacteria in our colon thrive on the fibers in healthy foods such as fruits, vegetables, whole grains, and pulses such as beans and lentils. They ferment the fiber and release short chain fatty acids (SCFAs) including pyruvate, lactate, and butyrate. This actually helps control our appetite. When the bacteria feed on the fiber and release pyruvate, the brain senses this and uses it to gauge the amount of food (which is the same as the amount of energy) you have consumed. When the brain measures enough pyruvate, it decides you have eaten enough and shuts down your appetite. This appeared in the American Journal of Clinical Nutrition in July 2016. Lactate is used to help eliminate problematic bacteria.†

Butyrate only lasts for a flash, like lighting a match, so a good way to keep it around long term is by maintaining a healthy diet and having enough good bacteria in your intestines. Butyrate gives the body energy for digestion, as well as for the absorption of key nutrients such as calcium and magnesium. It also gives the intestinal cells like the enterocytes and the colonocytes the energy to control the intestinal immune system. This is important because about 75% of our immune cells come into contact with our digestive tract every day. The butyrate that’s made by the healthy bacteria when you eat good foods also gives you energy for healing the intestines, and also helps to normalize colon cells. This helps reduce inflammation, as well as the risk of colon cancer, according to numerous studies.† 

But what does butyrate do for the brain? Butyrate helps create the blood brain barrier. This is additional insulation in the blood vessels in the brain. The same circulation that is in your toes and by your heart is the same circulation that enters your brain, so the blood brain barrier prevents bad things from exiting the circulatory system into the brain. Research is finding that having the healthier versions of bacteria in our gut offers some protection against dementia including Alzheimer’s disease and against depression. It can also help you cope with stress and anxiety, as well as Parkinson’s disease. The presence of these bacteria are also linked to overall brain wellness and can possibly help with migraines.†  


Let’s look at the psychological, mood and memory benefits of having these bacteria in your gut. A study done by the University of Verona in Italy in conjunction with their local hospital looked at how a daily dose of a multistrain probiotic supplement impacts mood in people with depression. The researchers found that it significantly improves mood, reduces depressive symptoms and anger, and improves sleep quality and fatigue.†

A randomized controlled human clinical trial conducted in Japan looked at how the bacteria in the gut impact memory. They worked with a strain of bacteria called bifidobacterium breve and a group of 80 normal-weight people aged 50 to 79 with mild cognitive impairment. Half of the subjects received the bacteria twice a day for 4 months, while the other half received placebo at the same frequency. The researchers found that scores on cognitive function tests absolutely improved for subjects on the probiotic. The findings show that it improved immediate memory, visuospatial construction, and delayed memory.† 

A report published in the journal Frontiers in Aging Neuroscience showed for the first time that probiotic supplements can help people with dementia. The researchers gave a daily dose of a probiotic supplement containing lactobacillus and bifidobacterium to people with Alzheimer’s disease aged 60 to 95 for a period of 3 months. This was enough time to yield a moderate but significant improvement in Alzheimer’s disease patients’ memories on a Many Mental State exam. That exam is a standardized test to measure the severity of memory impairment, so any improvement is significant.†

Listen To Your Gut! What Your Digestive System is Trying to Tell You

Listen To Your Gut! What Your Digestive System is Trying to Tell You

Understanding the digestive system can seem intimidating. But could your system be trying to tell you something? It may not be fun to talk about but complications with digestion can result in a multitude of digestive issues and associated health problems, like heartburn, constipation, and diarrhea.

Here’s what your gut may be trying to tell you.

You need to rebalance your gut bacteria.

Bacteria is commonly thought of as negative. There are plenty of harmful bacteria that can lead to a number of risks when it comes to the bacteria inside of your body. But with harmful bacteria comes beneficial bacteria called Probiotics. Research suggests that choosing a quality probiotic will help with digestion and help you maintain a healthy gut.†

Probiotics are friendly bacteria that make up the microbiome in your gut or digestive tract and are the key to good health, especially to good digestion and regularity. Bacteria, though naturally present in the body, accounts for two pounds of bio-mass in your intestines, which need a balance of beneficial bacteria to promote good health.†

Levels of probiotics decrease with age and can also be affected by other factors, including a poor diet and obesity. As the levels of probiotics decrease, problematic bacteria in the gut thrive, which can lead to digestive problems like bloating and gas.

You are feeling the impact of pollutants or chemicals.

We live in an increasingly polluted environment, loaded with toxins; the soil we grow our food in is often nutrient-depleted and many consume processed, factory-made foods supplying scant nutrients. Ironically, our bodies wind up requiring even more vitamins and minerals to effectively metabolize nutrient-depleted foods. Add that depletion with less time spent outdoors, minimal exercise, prescription drugs and medications, and chronic stress, and the result is that many individuals are truly nutritionally deficient.

To make your gut happy, be sure to monitor what you are putting into your body. Nutritionally, you’ll want to stay away from processed foods and turn to whole foods instead. Topically, be sure you are reading what is on the labels of your favorite products like your skin cream and cleansers. Sixty percent of what you apply onto your skin gets absorbed into your body and blood stream.

Here are the ingredients you should be avoiding in your skin care products!

You have a weak immune system.

Did you know that a good portion of the immune system is in the gut? Bacteria in the gut produce B-vitamins, but depending on the condition of your gut, the amount of nutrients being absorbed can be hindered. Frank Lipman, MD explains, “When your gut is balanced with good bacteria, it works properly to defend your body from infections, colds and illnesses. If there’s an imbalance, the body loses its ability to cope and ward off bad bugs, which leads to frequent sickness.”

The first step to strengthen your immune system is to focus on restoring and balancing your microbiome. To do that, you may want to turn to Probiotics. The next step is to turn to key enzymes that can help breakdown and improve your digestion, to help increase the absorption of nutrients into your body. Studies have shown that Bromelain, sourced from pineapple, is an enzyme that supports healthy digestion of proteins. Lactase is an enzyme that helps break down lactose to support the digestion of dairy products.†
