Thanksgiving just isn’t complete at many of our tables without Pumpkin Pie. Would you agree?

That pumpkin pie spice and cinnamon scent of a baking pie, be it Grandmother’s recipe or Libby’s suggestions off the side of the pumpkin can, is standard beloved aromatherapy of the season, so it’s with a smile and a wink that I post this recipe for you today. If not for the Turkey Day table, it might be a great additional to next Sunday’s dinner!

My friend Donna Schwenk has recently launched her new book called Cultured Food for Health. On page 154 of this wonderful book she offers a “Raw Kefir Pumpkin Pie”.

Okay, so ‘raw’ kind of defeats the aromatic aspect of the traditional celebration, but I’m hoping the greater value of this recipe may pique your interest, since it will provide so very many helpful probiotics for your family’s digestive tracts. I’m sitting here laughing at the image of a pie filled with multitudes of good bacteria. And it’s really the truth.

Kefir packs between 30 and 56 different types of bacteria, and research on the health of the gut shows over and over that diversity is the key – the more different types of good guys, the stronger your immune system seems to be. Let me know if you try this, and how you like it!


Donna’s Raw Kefir Pumpkin Pie

Makes 8 servings


For the Probiotic-Packed filling

1 cup raw cashews, soaked for 3 to 4 hours in water and then drained

1 cup pumpkin puree

1 cup Kefir Cheese

½ cup maple syrup (or a zero calorie sweetener like erythritol/lohan)

½ cup coconut oil, melted

2 teaspoons vanilla

1 teaspoon cinnamon

1/8 teaspoon Celtic Sea Salt

1/8 teaspoon ground ginger

¼ teaspoon nutmeg


For a raw crust (or of course, you can make your own recipe or pick up a frozen gluten free one!)

1 cup walnuts

1cup pecans

1 cup raisins

Pinch Celtic Sea Salt


To make the probiotic filling, combine the cashews, pumpkin, kefir cheese, maple syrup, coconut oil, vanilla, cinnamon, salt, ginger, and nutmeg in a blender or food processor on high speed. Pulse until completely smooth. This can take a few minutes.

To assemble the crust, pulse the walnuts and pecans in a food processor until they’re crumbs, then add the raisins and salt and pulse until the moisture begins to stick together.

Pour the filling into the crust, then cover it with plastic wrap.

Place the pie in the freezer until solid, about 5 hours. Before slicing and serving, let the pie sit at room temperature for 10 minutes to soften a little.

Donna offers a wonderful recipe in her book to make Coconut Whipped Cream to top this fabulous pie! You’ll find it on page 179 of the book when you bring one home for your very own.

As an alternative, I like to whip up some organic heavy cream and add a bit of stevia or zero calorie sweetener to taste. And let’s not forget the eternal crowd pleaser – delicious ice cream as a pie topping.

Whatever your combination, I wish you a Happy Healthy Joyful Thanksgiving filled with lots of great food and love all around! Don’t forget those probiotics! They love you too!

The University of South Florida here in Tampa is known for its world-class research and treatment of diabetes. Over the last 15 years grant monies have supported the Diabetes Center’s efforts to examine both prevention and environmental causes of this dramatically rising health risk.

An interesting article in The Tampa Tribune just the other day reported exciting findings of a new study spearheaded by USF researcher Ulla Uusitalo. The results stated that infants with a high genetic risk of developing Type 1 diabetes who were given probiotic-rich formula or supplements in their first 27 days of life were 60% less likely to develop islet autoimmunity, a precursor to the disease. Wow!

Uusitalo, an associate professor of pediatrics at USF, worked with an international team of coauthors and researchers studying the diets and blood samples of 7,473 high-risk children, ages 4 to 10. The study was conducted between 2004 and 2010 and the children studied lived in such diverse places as Colorado, Georgia, Florida, Washington as well as Germany, Finland and Sweden. The study is known as “The Environmental Determinants of Diabetes in the Young” and the future intention is to follow the children until they’re 15 years of age.

Although Uusitalo is very clear that the study doesn’t prove that probiotics can prevent the disease, it is nonetheless heartening that research is now looking at what might help prevent a disease from manifesting, as opposed to focusing on what might cause the disease symptoms to develop. What an important distinction!

The article, published this month in the medical journal JAMA Pediatrics, is one of the first of its kind, and I’m so happy to see that the star of the show is probiotics! Those good bacteria deserve lots of applause!

As Thanksgiving week approaches, I’m very grateful to reflect on the positive direction that awareness of our microbiome (that garden in our gut) seems to be moving. I’m also thankful each time I see another article that educates on the harmful effects of sugars and processed foods and offers healthy alternatives.

I can’t think of anything that has a more profound effect on overall health than feelings of gratitude. So at this happy time, I wish you many grateful moments, and lots of probiotics too.

You may have seen my newsletter this week where I discuss the low-fat misinformation that set so many of us on the SAD way of eating! (Standard American Diet). Contrary to the assertions of the Dietary Guidelines created in the 80’s, current research points out that full fat dairy can for many people actually be a very healthful food.

Yet for some, milk may cause allergic reactions due to the lactose (milk sugar) it contains. That group of people may have found in the past that they can tolerate dairy products when they take specific enzymes called lactase.

Another, even better way to reduce the lactose in dairy is to ferment milk, which then produces kefir. Through this process, most of the milk sugars are reduced making the milk more digestible (for everyone) and also giving kefir it’s somewhat sour taste.

The best news is that kefir can provide you an inexpensive and easy way to dramatically increase your daily dose of probiotics – those good bacteria we all know and love!

Do you like yogurt? If so, you’ll most likely enjoy kefir. I’ve been talking about the probiotic benefits of some types of yogurt for many years now. Where yogurt provides only a few different types (strains) of good bacteria, kefir has been found to offer between 30 and 50 different ones! The more strains the better it seems, whether we’re looking at estrogen balance, as protection against childhood allergies, or even regarding weight loss.

Making kefir actually predates refrigeration as a way to preserve milk longer. We now realize all the great probiotic benefits we gain from the process – benefits like healthy bowel movements, a strong immune system and more restful sleep, just to name a few.

You can find kefir at your local grocery or health food store in the refrigerated section next to milk. Be sure and choose the unsweetened variety. The process is so easy though, I would recommend making your own. Donna Schwenk, author of Cultured Food for Life, offers great how-to instructions on making kefir and other fermented goodies.

I know you’ll love the many wonderful ways to use this healthy food. I add kefir to my smoothie, I use it as a topping for berries, often as an ingredient in salad dressing, and it makes a wonderful probiotic coleslaw too!

This season invite some fermented foods into your life. You might begin with guilt-free dairy by choosing full fat organic milk (or even goat’s milk) and culture some kefir. It’s always a great day to support the good bacteria in your gut!

Goodbye to summer! I hope yours was enjoyable and relaxing.

Here in Florida, we’re hoping that the heat will lift soon. The kids are headed back to their classes and with the new school year comes the inevitable increase in colds and flu. Lots of excited little human beings in an enclosed space together, laughing, touching and generally sharing their bacteria with anyone in coughing or sneezing range.

How can we parents help to support our children’s immune systems and overall health while minimizing the chances of bringing home the newest variety of bacteria or virus?

Although these simple habits can be taken for granted as obvious, verbal suggestions and leading by example seem to make all the difference. We all remind each other to:

  • Wash hands after using the bathroom.
  • Sneeze or cough into our inner elbow, rather than into our hands
  • Try not to put fingers into noses or mouths – generally avoid touching the face
  • Avoid the drinking fountain at school – bring bottled water if possible – there are some great eco friendly options available

And my favorite – it’s never too soon to teach our children about the dangers of sugar, and that sugar actually increases their chances of getting sick by feeding bad bacteria that make for unhappy sneezes and coughs. So minimizing sugar, both at school and at home, is one of the healthiest things we can all do together.

Which brings me to something I’d really like to say. Over the last decade, I’ve watched our awareness slowly shift from simply treating symptoms of disease to the sound concept that maintaining our natural health is the most intelligent choice we can make – on a daily basis. Sadly, American marketing techniques are often ahead of our best intentions.

Natural health isn’t always “natural” or “healthy”. We can be tricked by products that might contain a few positive nutrients lost in other ingredients that are downright unhealthy, like sugars. Gummy vitamins are the perfect example.

Sure, our kids love them because they taste like candy. Guess what – they ARE candy! And candy isn’t the way to maintain health – period.

Moms and Dads, please read the labels on those supposed healthy vitamins. If you go to your local health food store and ask, they will show you products that are sweetened with stevia or erythritol or other healthy sweeteners. Spend wisely and really preserve your children’s wellness.

Two other valuable tips:

  1. After breakfast, be sure to give your children a quality multi-vitamin that contains extra vitamin D and,
  2. Before bed, give your kids a probiotic. Their immune systems will love you for it!

Misery and suffering can be optional. Let’s all maintain our health together.

I’m writing to you today as I fly home from Baltimore. My assistant, Dr. Jemma Sinclaire and I traveled there to officially begin a clinical trial that has been in the works for a couple of years now. I hope you enjoy the story of how this project came to be.

Years ago I met Dr. Amando Sardi. He’s an extraordinary gastroenterologist and oncological surgeon at Mercy Hospital in Baltimore, Maryland. Dr. Sardi and his team have perfected a surgical technique that has saved countless lives. When cancer is found in the gastrointestinal tract, many times a part of the intestine needs to be removed, along with other organs, like the gall bladder, spleen, and/or parts of the liver or stomach that may also be cancerous. Removal of parts of the intestine is called “bowel resection”.

Historically, after a surgery of this type, a person would then have to undergo whole body chemotherapy, a difficult and extremely taxing process to endure. It was not uncommon for the cancer to be technically gone, however the patient may have passed away from complications of the treatment.

Dr. Sardi’s unique treatment “perfuses the peritoneum” with chemotherapy. That means that after he removes the obvious cancerous growths and parts of the intestines that are involved, he fills the intestinal cavity with the cancer killing drug instead of allowing it to travel the entire body. In this way, the medicine is focused in the exact area where any remaining cancer cells may be, sparing the rest of the body from the debilitating side effects of chemo.

The total procedure is called Cytoreductive Surgery with Hyperthermic Intraperitoneal Chemotherapy (HIPEC) and Dr. Sardi has an amazing survival rate when he performs this protocol. However, after the initial healing phase, the quality of life the patients experience is often “in the toilet”. Sadly, chronic diarrhea is often unrelenting.

The term “Short Bowel Syndrome (SBS)” is used to describe those symptoms that may arise after bowel resection, diarrhea being one of the most persistent.

Initially, after a dramatic procedure of this type, there is a period of time during which a person’s body is stabilizing and adjusting, attempting to compensate for functional loss. It constantly amazes me how the human body is able to recover from that level of trauma.

Then the next phase of healing begins. Dr. Sardi’s vision, to be explored during the clinical trial, is to introduce appropriate nutritional support, through diet and supplementation along with targeted medication that will help a person to experience the highest quality of life possible. Surviving cancer surgery is one thing. Living life after cancer with a compromised intestinal tract is quite another.

This clinical trial was birthed in a conversation Dr. Sardi and I had about what might be possible for these people who had already endured so very much.

Through the Renew HOPE Foundation, Dr. Leonard Smith, Jemma and I along with Dr. Sardi’s team have designed a one-year research project that includes 10 patients who are all at least 2 years post surgery. Their cancer markers are within normal ranges. They are grateful to be alive.

We are teaching them about the HOPE Formula (High fiber, Omega-3s, Probiotics and digestive Enzymes) which I believe are the foundation of digestive health – for everyone.

Additionally we’re using aspects of the Skinny Gut Diet and are helping these people to rebalance the bacteria in their remaining bowel. It always comes back to supporting the good bacteria when you’re goal is improving digestive wellness and supporting the immune system.

I hope that soon we will be able to relate to you that the quality of life these people experience will be much improved.

I felt truly honored to meet with our first 5 patients along with Dr. Sardi and his excellent team, and I look forward to our next year together. I promise to keep you updated.

Fermented foods are on my mind today. Yes, I’m glad to see that there’s an article about their health attributes written about them nearly every day. In contrast, it’s interesting to me how often I’m asked if my recent eating plan, Skinny Gut Diet, can “work” if a person doesn’t like fermented foods. Someone just the other day posed that in our Facebook support group.

When I created Skinny Gut Diet – even though the word “diet” is in the title, I envisioned this program much more as an eating plan – for life. And the reason fermented foods were included was their incredible health benefits.

Having been such a strong advocate of probiotics for so long, I’ve been fermenting in many different ways for decades. So my answer to the question was – if you are only interested in “losing” weight – eliminating processed carbs, increasing good fats, regular protein intake, essentially following the 3 rules of Skinny Gut Diet, will certainly direct you to reach your goal. By the way, Rule #2 is “eat living foods daily”. “Living foods” includes both non-starchy vegetables as well as fermented offerings, so you can understand how weight loss might result, even sans fermented goodies.

What’s important to understand in the bigger picture of creating a life of vibrant health is – omitting fermented products will negate an easy and affordable way to balance your gut with good probiotics. Those helpful microbes support stronger immunity and detox capabilities for your body.

In my newsletter recently I wrote about my granddaughters, and how varied their palate is due to the fact that they had only been offered healthy foods to eat since birth. Fermented foods like sauerkraut were among their choices, and they now love them.

It’s clearly a matter of “palate conditioning”. And if you don’t enjoy fermented foods, listen up – it’s not just about pickles and sauerkraut at all!

I know – it’s the sour taste you just don’t like. Well there are recipes that include some sweet aspects that persist even through the fermentation process. My friend Donna Schwenk offers this one – Cultured Broccoli Salad in a Jar. The grapes retain much of their sweetness, probably because the outer skins are left intact. Really yummy.

And I look at it this way. If the requirement for a sweeter taste is what’s blocking you from fermented foods, and you’re eating sweet stuff anyway in other foods, then when you prepare your fermented foods, add in a bit of sweetener. Isn’t it better to eat something sweet that contains wonderful probiotics too, than just something sweet made with other forms of carbs?

Another friend of mine has a recipe for Pickled (fermented) Beets that she makes. Everyone loves it! One day I asked her for the recipe and was somewhat dismayed to learn that she adds in a bit of sugar AFTER the fermentation process. No wonder it was so delicious. Although personally I didn’t eat the beets again quite as voraciously, it occurs to me that for those of you who have that sour aversion, this could be an option. You just need to calculate approximately that added sugar when you’re noting it in your daily food journal.

And don’t forget the option of kefir! Did you know that milk kefir contains 35-50 different strains of bacteria? Now that’s diversity.

Kefir can be added to everything from coleslaw to pudding. Here’s a great recipe we include in Skinny Gut Diet for kefir ice cream! Imagine that favorite treat – guilt-free! And remember to substitute zero-calorie sweeteners like erythritol or stevia for at least 2/3 of the regular sweetener suggested in other dessert recipes. This will lower your sugar count considerably.

Also consider kombucha. It’s now available even in grocery store chains. Kombucha offers you the gut balancing good yeast called S. boulardii. Often store-bought kombucha can be a bit too sweet, so limit this, or dilute it a bit. Your label is your guide, so be sure to check it out.

If you’re not a kitchen type, no worries. I simply can’t believe that you won’t find a recipe you will learn to love right here. The great news about fermenting is that the bacteria do the work for you. Yours is a simple assembly job. Couple that with a dash of willingness to experiment – for the good of your own gut – and I’ll bet you’ll be eating fermented foods in no time. Palate diversity is a very good thing.

Happy fermenting!

Constipation may not be a topic you’d choose for daily conversation, but it’s really nothing to be embarrassed about. We’ve all experienced it at one time or another – and we realize how debilitating it can become. Although in our society, the medical professionals still say that 3 bowel movements weekly is “normal” – let me tell you, you don’t want to be “normal”. A healthy human being should eliminate daily. And it’s the same for our faithful canine companions.

Dogs also suffer from constipation. If your dog is showing signs of having trouble eliminating, take him to the vet to make sure there is not an underlying condition. If there’s not a physical problem, then it’s up to us, and what we provide as owners, to help our dogs eliminate better.

Dogs show signs of being constipated by straining to defecate – with small volume expelled. You may notice hard bowel movements. As I mentioned, dogs need to eliminate everyday to be healthy. They may also look bloated and/or show signs of pain when attempting to defecate. Lack of appetite or even depression could be a sign of toxic buildup or discomfort due to constipation. Be sure to notice any differences in color or texture.

Well, what exactly can we do at home to help our dogs? Making sure they eat a good diet with moist food – not just dry food – is a must. Supply your pet with plenty of clean water and exercise.

Certain supplements have also been shown to help. Just like people, dogs need the good bacteria from probiotics to balance their guts and help with regularity. Choose a supplement that is potent enough to make a difference – at least 20 billion cultures per serving (whether in pill or powder) and containing 10 different strains of lactobacillus and bifido bacteria. Dogs have many of the same strains of good bacteria in their gut as their owners so providing them with a high culture count and multi strain supplement is as important for them as it is for us.

Here’s another important tip that many may not know – Omega 3s, which vets suggest for many other problems in dogs like kidney, heart and joint diseases, is also very effective in relieving constipation. A high dose omega blend of EPA and DHA totaling about 750mg of total omega3 is best.

Chances are good that you regularly clean up as your dog eliminates. That poop helps you to notice any changes that may be occurring in your pet’s health. Our dogs are so willing to give us unconditional love – and we enjoy it thoroughly! However they depend on us totally for their digestive needs. Let’s make sure they have the same opportunities for vital health that we do!

Statistics show constipation in humans is an extremely common and sometimes very expensive issue. Too often people end up in the doctor’s office or emergency room when the problem becomes painful or even potentially dangerous due to the fact there could be a blockage of some kind.

Well, our dogs and cats can have the same problem with constipation, even though diarrhea is seen more often in pets.

I’ll bet most loving pet owners pay more attention to how their animals poop then they do to their own poop – an interesting thought in itself.

What is the very first thing a vet will ask you when you take your animal in for a problem or an exam? “How are they pooping?” Right? Wouldn’t it be great if our human doctors asked us that on our regular check-ups? Most doctors haven’t been trained to consider it very important. I’ll sadly tell you that from lots of experience.

Back to our pets. Let’s start with cats. Cats should poop every single day. If you are disciplined about cleaning out that litter box you will be able to monitor this easily. Their poop should be brown, formed (not loose) and soft and moist enough for the litter to stick to it. Simple enough. If this is not happening then your cat is constipated.

Not every cat is going to let you know if they are uncomfortable because they are constipated. People will think it’s normal for their cat to go once every 2 or 3 days! Cats, like humans, are supposed to detox through their poop – every day.

So if you believe your cat is constipated, first take them to the vet to be checked. It’s important to make sure there is not a blockage or serious problem. After that, it’s time to consider some steps you can take at home to help remedy the problem.

The biggest issue with cats and constipation is dehydration, so make sure your cat is eating a moisture rich food. Did you know that cats are designed to get the majority of the water they need from what they eat? Actually 70-75%. Studies show that generally a dry food diet may not be the best choice for your cats. They won’t realize they need to make up the moisture difference by drinking more water. It’s impossible to force them to drink more water than they normally desire. Of course, be sure they have plenty of fresh, clean water available at all times so they can drink when they’re thirsty.

Natural remedies for constipation are as effective and safe as those made for humans. The addition of aloe vera juice into your cat’s food may be very helpful.

Perhaps one of the best solutions is to increase the good bacteria in your cat’s digestive tract with probiotics. Make sure you choose a probiotic that is formulated specifically for cats. Just like in people cats need a high potency probiotic with at least 10 strains.

Using a powdered probiotic that can be added to your cat’s food makes supplementing with probiotics effortless. I’m sure you’ve experienced how interesting (or impossible) it can be in many cases to persuade your cat to take a pill. A powdered form removes that issue all together.

I’ll bet you’re relieved to know that there is so much that can be done to help your feline friends should they suffer from constipation. I can say with sincerity, having suffered from it myself and having worked to help countless others – you just feel miserable. We certainly don’t want our loving pets to live in misery, as they bring us so much JOY!!!!

Let’s help them out.

For many years I have written about the benefit of probiotics on our health. In my early years, working in a Natural Health Clinic that offered total health solutions, I experienced first hand the great effects probiotics have on people. I worked one on one with many who were trying to reverse health conditions naturally or in conjunction with traditional medicine. In my own practice as well as throughout the clinic our goal was to assist people in detoxification of their bodies. These cleansing practices were found effective in prevention of disease, as well as in supporting the healing of many conditions that traditional medicine had not been able to solve.

In our Clinic this was accomplished with modalities like massage, sauna, herbs, colon hydrotherapy, juice fasting and nutrition. During this period of time probiotics were a vital part of my practice. My specialty was the digestive system (I’ll bet you might have guessed!) and I was performing colonics as well as suggesting herbal remedies and teaching good nutrition. So in this way very early on, through practical application, I observed over and over how probiotics could greatly improve people’s health.

Now let’s fast forward to today – many years later! We have entered the age of the study of the Human Microbiome (fancy name for gut population) and its effects on human health and disease. The National Institutes of Health (NIH) has supported this so scientists can have the funding to study all aspects of bacteria, both in and on our bodies. Almost daily we can read more research studies touting the benefits of probiotics on everything from GI problems to anxiety and depression. As new studies have come forth, we have even offered many of them to you on this blog.

Since we have trillions of bacteria and over 180 different strains of bacteria in our guts, we now fully realize two important things – how critical it is to replenish our good bacteria if we want to be healthy, and also just what type of probiotic supplement our bodies need most – one that is high potency (meaning a high culture count) and that also contains many different good bacterial strains.

BUT – have we forgotten about the digestive systems of our babies? Those wonderful animals that keep us company, are always excited to see us and never criticize us for our shortcomings? Gosh I hope not.

Come to find out these guys (dogs and cats) need probiotics just like we do. In fact their digestive systems take a beating from antibiotics, anti-inflammatory drugs and toxins just like ours do. Actually they are finding that the gut bacteria of the animals we live with actually mimic ours, having many of the same bacteria – even though there are certain strains that are specific to animals.

I interviewed Dr. Rob Knight who is a scientist studying the gut microbiome and founded The American Gut Project. These scientists actually analyze stool samples (for a fee) from anyone, and they will accept your animal’s sample as well. Dr. Knight explained to me that he can take samples from humans and match them to their dog by simply comparing their bacterial composition, without knowing anything else about them. He can literally match owners with their dogs through their similarities of bacteria!

Even though “official” research is beginning to demonstrate that dogs and cats derive many health benefits from probiotics, Stan and I and countless other dog owners and vets have already experienced that high dose, multi-strain probiotics can help pets with digestive upsets like vomiting, diarrhea, and constipation, skin issues – the list goes on. For cats and dogs, a healthy population of gut bacteria is vital for gut health, and just like with their humans, plays a critical role in removing toxins, enhancing digestion and out-competing many strains of disease causing microorganisms.

In conclusion, I know I am going to make sure my animals have the benefit of quality probiotics – ones made especially for cats and dogs – with at least 20 billion cultures per capsule and 10 different probiotic strains.

In this simple way we can provide our animals a much better chance of keeping their health on the right track — so that we have them around longer to love!!! YEA!!!

Scientists are hard at work researching the effects of probiotics and prebiotics on metabolic abnormalities such as those seen in people with diabetes and related conditions. A recent study published in the journal Diabetes highlights the effects of a Lactobacillus probiotic on blood sugar levels. The researchers engineered the Lactobacillus strain to secrete glucagon-like peptide 1 (GLP-1). Glucagon-like peptide-1 is normally produced in the small intestine and stimulates insulin release to lower blood glucose levels.

People with diabetes are either unable to produce enough insulin (type 1 diabetes) or the body’s cells do not respond properly to insulin (insulin resistance) due to an overabundance of insulin produced in response to continually high blood sugar levels (type 2 diabetes).

In an animal model, the GLP-1–producing probiotic induced the conversion of intestinal lining cells so that they would produce insulin, much like beta cells found in the pancreas. “It’s moving the center of glucose control from the pancreas to the upper intestine,” noted John March, PhDlead researcher. The probiotic reduced blood sugar levels in diabetic rats by up to 30 percent.

This proof-of-concept study will need to be followed up with more study to determine dosage, and later in humans to determine efficacy, but it shows promise that we might soon be able to better control blood glucose levels by targeting the site of glucose absorption.

Some evidence in humans does exist, however. For example, a recent human study published in the British Journal of Nutrition found that people who ate a high-fat, high-carbohydrate diet and also drank a probiotic fermented milk experienced less insulin resistance than those individuals who did not drink the probiotic milk.
