Why Consistent Healthy Eating is More Important Than a Cleanse

How long term healthy eating is better than detoxing or cleansing | why you should have a consistent healthy diet | how diet affects gut health Nutrition, nutrition, nutrition! Nutrition is big news these days because, well, nutrition is everything. Nutrition is nature’s medicine. Nutrition is life. Diets, cleanses, and detoxes are also mainstream in the health and wellness world for people trying to reset their body, lose weight, and live a healthier lifestyle. These types of short term diet changes have their place and benefits. I believe doing a gut reset, liver detox, or whole body cleanse from time to time can be very beneficial for overall health. Short term diets should not be relied upon, however, for whole body health. Your long term diet is the most important determining factor for overall health. This may seem obvious, but it goes far deeper than just healthy eating for weight loss and heart health. Long term diet can make or break the health of your entire body.

This holistic approach to health and nutrition is important, because the nutritional content of the food you intake affects the bacteria living in your gut. The gut microbiota is basically like another organ. It is a complex interconnected ecosystem of microorganisms that are essential to the health and wellness of the host (that’s you). How so? The gut microbiome affects brain development, mood, depression and anxiety, the immune system, inflammation, digestive function, and gut permeability (7). These tiny warriors provide benefits to us by the production of short chain fatty acids (SCFA), vitamin K, fermentation of undigested food particles, protection and barrier function, and immunologic regulation (5). The gut microbiota functions on a delicate balance of beneficial and harmful bacteria. Many things determine the diversity of the gut bacteria and the species of organisms it contains, including development, age, genotype, environment, sex, antibiotic use, stress, and you guessed it…your diet.

Establishment at birth

In order to understand the microbiota, we have to start from the beginning. A tiny fetus is living in a completely sterile environment. In a natural birth, a baby is born without any medication and is held against mom’s body thus exposing him or her to mom’s vaginal and skin flora. This is the beginning of baby’s gut bacteria. From here on out, pretty much everything begins to shape baby’s gut flora. Studies have shown babies born via c-section vs. vaginally have different dominant strains of bacteria, as well as babies fed formula vs. breastmilk (3). Over 700 microbial species have been identified in human breast milk (5), and this exposure continues shaping the infant microbiota in breastfed babies. Gestational age, antibiotic use, pets, and other family members also begin to affect baby’s gut flora (7).

Development of the gut flora

The biggest change toward a permanent and stable adult gut flora begins when the baby starts solid food (3). This time of life is crucial, as the gut bacteria reaches it’s permanent adult state by age three and becomes far more resilient (7). In the absence of antibiotics, diet is the main controlling factor of the gut microbiome, as was shown in a study comparing African children to Italian children. In this study, the dominant gut bacterial species were largely determined by the main food source of the population, whether it be plants, meat, or carbohydrates (5). The gut microbiota adapts to the nutritional content of the diet. In fact, it can even code for special enzymes specific to common foods of a culture— the Japanese have a species of bacteria that codes for an enzyme used to digest seaweed (3).

Resiliency in adults

The gut microbiota is resilient in adulthood. It is more similar within one person on a day to day basis than between  different people. Monozygotic twins may even have a 50% difference in gut bacteria (3). Again, long term diet is the biggest determining factor of gut bacteria  aside from situations like antibiotic use, which can wipe out the good bacteria and allow overgrowth of harmful organisms.

How diet affects the gut microbiome

As many of us know, the high fat, high sugar, processed food diet of America is not ideal. This kind of diet  is linked not only with inflammation and obesity but leaky gut, depression, and many other health problems (7). Leaky gut, or increased intestinal permeability may lead to high levels of endotoxins in the blood stream that contribute to chronic inflammation and autoimmune disease (7).

An interesting study on gnotobiotic (sterile) obese mice showed the obese mice were able to lose weight when transplanted with the gut bacteria of thin mice (3). When fed a diet high in saturated fats, this effect was diminished (3). In other studies, mice fed a high fat, high sugar diet for 28 days were compared with mice fed a diet of chow. Surprisingly, changes in the gut microbiome were documented as early as 3 days; this change included a decreased in Lactobacillus, a highly studied and beneficial group of gut bacteria (2). Interestingly enough, at around 14-28 days the microbial changes began to stop, although some species were more sensitive to changes than others (2). After about a month of a similar diet, the gut bacteria stayed fairly consistent. This shows overall, long term diet is crucial in the determination of the permanent microbiome.

Cognitive impairment

Aside from immune system problems like inflammation and autoimmunity, poor gut health can affect cognitive function along the gut-brain axis. As stated earlier, consumption of a high fat, high sugar diet may impair gut permeability, which contributes to chronic, systemic inflammation and cognitive impairment (8). Poor diet has also been associated with damage to the blood brain barrier in as little as 90 days (8). Cognitive impairment includes but is not limited to ADHD, anxiety, depression, autism spectrum disorders, and behavioral disturbances. Studies have linked autism spectrum disorders with major gut bacterial disturbances and a slight increase in intestinal Candida (12).

Antibiotics and gut disturbances

I am not against proper antibiotic use. They have their place and they save lives. However, they should not be taken lightly or misused, and I believe when using them one should absolutely be on good probiotic.

Apart from diet, antibiotic use is the other major factor in determining the gut microbial balance. The gut microbiome can become severely affected by antibiotics (9,10). After antibiotic use is stopped, the gut microbiota has lost much of its diversity. The recovery time varies in the individual,  but without any treatment the disturbances can persist long term (10). Different microbial species are affected by antibiotics at  a varying rate, but many times pathogenic organism overgrow in the absence of a healthy gut flora, this including Clostridium difficile and Candida albicans. Clostridium difficile is an anaerobic microorganism that causes severe and persistent diarrhea in patients who have taken antibiotics, many times who are hospitalized. It is incredibly contagious and increasingly more difficult to treat.

Candida albicans is a commonly known yeast that is normal in small amounts in a healthy intestine but a menace when it becomes overgrown (11). Once Candida begins taking over the gut, it may lead to many health problems including chronic vaginal and skin yeast infections, digestive disturbances, immune system malfunction, and neural problems (13). A diet high in sugar and grains encourages Candida growth, increases symptoms, and contributes to leaky gut (13.) For many, the only way to heal their gut, reduce overgrowth, and decrease intestinal permeability is to eliminate sugar and grain from the diet entirely. Although it goes greatly against the standard American diet, this practice is becoming more and more common for many people struggling with cognitive disorders, autoimmune disease, digestive disorders, skin problems, chronic inflammation, allergies, anxiety, and depression.




Probiotics

How do probiotics fit into all of this? A probiotic is a beneficial microorganism that provides benefits to the host. Probiotic supplements and probiotic rich foods are becoming more and more mainstream, and for good reason. Not only can they improve immune function, they have also been shown to impact digestive function. They work by improving the microbial equilibrium in the intestine and activating fermentation of soluble fiber to produce short chain fatty acids (SCFA) (5). SCFA are the main nutrient source of the intestinal cells in the colon, and they also play a role in increasing blood flow and water absorption (1). Probiotics have also been shown to positively impact intestinal permeability (7). S. boulardii can decrease diarrhea in children, and other probiotics have been used to treat diarrhea caused by antibiotic use (6). Case studies have shown that probiotics may increase the number of beneficial gut flora (5).

Studies have shown that probiotics may not always colonize the host, which is why it is important to make them a regular part of your diet (6). In one study, a diet that restricted fermented foods led to a decrease in the innate immune response, a decrease in fecal leukocytes (white blood cells that fight infection), and a decrease in Lactobacillus in the stool (6). Therefore, to keep stable levels of probiotics in the gut, one must intake supplements or fermented foods frequently (5). It is important to note that the effects of probiotics will be different for different people based on variations in gut flora, age, and other environmental factors (5). Also, not all probiotic supplements or fermented foods are created equally; this difference in quality will certainly impact results.

A healthy gut sets you up for a healthy body

Why is it so important what the dominating bacterial species is in your gut? Each organism provides a separate benefit to the host. For example, the lactic acid forming bacteria such as Lactobacillus and Bacteroides are the main produces of SCFA. The microbiota is so complex that little is known about the vast amount of functions and benefits it provides. Although we don’t know exactly what every single organism does, we do know that keeping the gut diverse and balanced is essential to good health. A healthy and diverse gut microbiome is necessary for proper function of the immune system, brain, gut, and body as a whole. Because long term diet is such an important determining factor, it is absolutely essential to adopt long term healthy eating habits which include a diet low in sugar, processed food, refined grains, and unhealthy fats, and high in whole, unprocessed, organic, and nutritious foods. It also means that when you have established a long term highly nutritious diet, a cheat meal or dessert every once in awhile isn’t going to set you back as long as you are not battling a disease.

Simple summary of this post

For those of you would prefer not to read about studies and research, here are the main takeaways of this post.

1. Gut bacteria and gut health are related to the proper function of the immune system, digestive system, brain, and body as a whole. A balanced and diverse gut microbiome leads to a healthy gut.

2. Long term diet is a major determining factor in how balanced and diverse your gut bacteria is; the microbiome adapts to the diet of its host. A cleanse or detox is beneficial, but more importantly is how you eat long term.

3. To keep the system balanced, a good approach is to eat a diet low in sugar, processed food, refined grains, and unhealthy fats, and high in whole, unprocessed, organic, and nutritious food as well as daily fermented foods or high quality probiotic supplements (especially when taking antibiotics).

  1. We’ve long battled Candida for my son with autism. It causes such behavior problems and destroys sleep quality. We’ve adapted the very diet you mentioned. Low sugar, no grain, high fat, but of course full of probiotic rich fermented foods. If we relaxed this diet for even a week, we’d start seeing it creep back up again. After years, it’s finally in check, and we’re hoping to keep it that way.

  2. This is such a great article!! I love all of the studies lately that have shown that seeding before c-sections is so good for baby, it provides them the beneficial bacteria that they miss out on when they aren’t born vaginally. It is my hope that eventually it will become common practice in ALL cesarean sections.

  3. Thank you for a thorough and well-referenced article. It is so refreshing to see that you are taking nutrition seriously. I’m currently looking into ways of adapting my food intake to the needs of my body. Love miso soup!
