Unveiling the Secrets of Gut Health- What are the F-Goals for Gut Wellness?

gut health

Gut flora are a common topic in health papers due to their profound effects on human health, but what are they anyway? Unexpectedly, most Americans are unaware of the gut microbiota and its significant impact on general health and wellness.

So, one should know how the digestive system works and how food affects gut health. 

When people talk about gut health, they refer to more than just the belly or stomach region. The gastrointestinal system starts in your mouth. The mouth is the first point of entry for food, which subsequently makes its way down the esophagus and into the stomach. The gut, which includes small and large intestines, is another digestive system component.

The Science of Gut Microbes. What Are They? 

Our GIT, or gastrointestinal system, is home to various microorganisms, including bacteria, viruses, fungi, and protozoa. Because of its diversity, this microbial population is often known as the “gut microbiome.” These tiny organisms are very important for digestion, vitamin synthesis, and even pathogen protection; they are far from being parasites. Understanding these little friends may help us better understand our health and the best ways to care for our internal ecology.

Inheritance, Diversity, and Evolution of Gut Microbes 

Did you know that the moment you are born is the first time you come into contact with microbes? But there’s some recent evidence that prenatal exposure to microbes could happen. (1) The gut microbiome is dynamic and changes during life due to factors such as food, environment, and lifestyle choices. When you change your lifestyle or health, your environment changes.

Also, it is well known that the gut microbiome is as distinctive as a fingerprint. And many things influence this diversity, such as,

  • Diet: Diet has a significant impact on the gut microbiota. A diet full of fruits, vegetables, and fibers promotes improved health outcomes. Conversely, a less diversified gut flora may increase illness risk, and a diet heavy in processed foods, sweets, and saturated fats is no exception.
  • Lifestyle: Lifestyle factors like physical activity, stress, and sleep significantly influence the gut microbiome. Regular exercise boosts gut microbiota diversity, promoting improved health outcomes.
  • Genetics: Research suggests that specific microbiome components may be passed down between generations, suggesting that genetics also play a role.
  • Environmental Factors: Early life exposure to various environments has the potential to influence the diversity and development of the gut microbiome. This includes natural environments, social interactions, and pets, all of which contribute to microbe exposure.
  • Medications: A few kinds of medicine can change your microbiota. Antibiotics, while life-saving, can significantly alter the gut microbiome by killing harmful and beneficial bacteria, decreasing microbial diversity, and developing antibiotic-resistant strains.
  • Alcohol Use: Consuming excessive alcohol might harm the beneficial bacteria in the digestive tract, reducing efficiency. Alcohol can cause inflammation in the stomach lining, impact stomach acid production, and reduce the stomach’s ability to destroy bacteria.

Gut Flora and Body Systems

Immune System and Gut: An Intimate Connection

The relationship between gut microbes and immune systems is a prime example of nature’s sophistication.

We all know that the human digestive tract is home to billions of microbes, such as bacteria, viruses, fungi, and protozoa. These microbes train your immune system to distinguish between friend and foe, which is essential in maintaining your health.

Role of SCFAs: Some microbial metabolites, such as short-chain fatty acids (SCFAs) generated when dietary fibers undergo digestion, known later as postbiotics, can modulate the immune system. In addition to regulating the activity of immune cells, SCFAs provide energy for gut epithelial cells and encourage anti-inflammatory responses while reducing pro-inflammatory ones.

The Intestinal Barrier as an Immunity Holder: The intestinal barrier is an initial buffer between the body and harmful substances.

A single layer of epithelial cells connected by tight junctions controls the entry and exit of substances into and out of the stomach. Immediately behind this epithelial layer is the gut-associated lymphoid tissue (GALT), the body’s biggest immunological organ. The GALT is the resident organ of many immune cells, including dendritic cells, macrophages, T cells, and B cells. These cells respond to pathogens and antigens that enter the gut lumen.

When the intestinal barrier isn’t totally locked down, it increases permeability and allows dangerous chemicals and pathogens to enter the bloodstream, called a “leaky gut.” Immune-mediated illnesses like inflammatory bowel disease (IBD), allergies, and autoimmune disorders can cause systemic inflammation.

So, an imbalance in your gut microbiome can lead to an overactive immune response, which is implicated in allergies, autoimmune diseases, and cancer. By nurturing a balanced gut microbiome, you can help ensure your immune system functions at its best.

Metabolism and Gut Health

The gut flora significantly impacts metabolism because it regulates energy balance, produces metabolites, and affects nutrient digestion and absorption.

Nutrient Absorption and Synthesis: Bacteria in the digestive tract help break down complex carbs, fibers, and specific proteins that our digestive enzymes can’t digest. The breakdown process yields short-chain fatty acids (SCFAs) such as butyrate, acetate, and propionate. These SCFAs are crucial for the host’s energy generation and positively impact metabolism. Butyrate, for instance, is known for its ability to reduce inflammation and help the gut barrier work better.

The Gut-Brain Axis: A Two-Way Street 

An individual’s stomach and brain are linked by a network of nerves known as the gut-brain axis, the most fascinating component of a healthy digestive system.  There are a lot of physical and biological ways that they are related.

Much research links the gut-brain axis with your hunger, mood, digestion, stress, pain, cognition, cravings, food sensitivities and intolerances, and gut motility.

Nervous System: The brain and the gut are physically connected via millions of nerves via different pathways. Thus, the gut microbiota may influence brain health by regulating the signals sent to the brain via these neurons. Among these networks, the connection of the vagus nerve is the most prominent one. The vagus nerve carries information from the brain to the stomach, and gut discomfort can convey stress signals back to the brain.

Multiple studies have revealed that, in comparison to healthy individuals, those suffering from a variety of mental conditions tend to have a distinct variety of gut flora. (1)(2)

Hormonal Connection: Like the nervous system, our hormonal system can also affect gut flora. Hormones such as serotonin can influence brain function, temperament, and behavior and are produced via the intestines.

The Gut Microbiota: An essential part of the gut-brain axis is the gut microbiota, which consists of billions of bacteria. These microbes can produce neurotransmitters and other substances affecting brain function. They regulate the immune response and influence the brain’s reaction to stress.

Signs of An Unhealthy Gut

Like all of our other bodily systems, many symptoms can indicate that your stomach isn’t doing its job correctly, impacting your general health.

1. Digestive Issues

Nutrient absorption and proper digestion are both supported by a healthy gut microbiome. Digestion problems and pain can develop due to an imbalance in the gut flora. Symptoms like bloating, gas, diarrhea, constipation, and heartburn occur in such cases.

2. Unintentional Weight gain or loss

An unhealthy gut might cause you to gain or lose weight even when you change nothing about your diet or exercise routine.  More studies are linking poor gut health to obesity. Why? An imbalance of good bacteria in the digestive tract, known as gut “dysbiosis,” can lead to a change in the ratio of “healthy” to “unhealthy” microorganisms and a reduction in microbial diversity.

An unbalanced gut can also negatively affect fat storage, blood sugar regulation, and nutrient absorption. An obesity-related microbiome may flourish on a Western-style diet heavy in fat and processed carbs, according to research.

3. Food Intolerances

Intolerances of foods can develop due to unhealthy gut flora, as opposed to food allergies caused by immune system responses to specific foods.  This can make it harder for your body to digest the food items that set off your symptoms, including gas, bloating, diarrhea, stomach discomfort, nausea, and more.

4. Sleep Disturbances or Constant Fatigue

Sleep disorders, such as insomnia or poor sleep, can contribute to chronic fatigue, and an unhealthy gut can exacerbate these issues. The stomach is responsible for producing the majority of serotonin, a hormone that affects mood and sleep. Thus, difficulty sleeping could be a symptom of an unhealthy gut.

5. Skin Irritations

It might be a new thing for many readers, but Eczema, psoriasis, and other skin problems may have a connection to gut health.  When food allergies or a poor diet cause inflammation in the digestive tract, specific proteins can “leak” into the bloodstream, resulting in eczema and other skin irritations.

One study from 2021 found that eating heavily in refined sugar or saturated fat might lead to an imbalance in gut flora, which can aggravate skin conditions, including acne, rosacea, eczema, psoriasis, and dandruff. The same study also indicated that patients living with gut flora imbalances are more likely to develop rosacea and psoriasis, with an increase of 7% to 11% compared to the general population.

6. Autoimmune Conditions

It has been well documented that the immune system’s regular functioning can be disrupted and systemic inflammation exacerbated by an unhealthy gut. Autoimmune disorders can emerge when this happens because the immune system starts targeting healthy tissues.

7. Bad Breath (Halitosis)

Halitosis, or chronic foul breath, can be associated with several gut health problems. If you notice an overabundance of unpleasant smells in your mouth, it might indicate an imbalance in your gut or mouth microbiome. Another cause of poor breath is the regurgitation of stomach contents, which can be brought on by illnesses such as gastroesophageal reflux disease (GERD).

8. Changes in the Poop Color

Changes in poop color can sometimes be a sign of an unhealthy gut, but not always. Food, water intake, medications, and nutritional supplements are just a few things that can affect various factors that can change the color of the stools, which will all be read here in our detailed article. Here.

If you’re worried about a change in the color of your poop, especially if you haven’t changed your food or medicines recently, you should always consult a doctor.

9.  Migraines

If you feel nauseous or vomit during a migraine, then it might also indicate a gut flora imbalance. Some studies, one from 2016 and another from 2022, also suggest that individuals who experience frequent migraines may also have gastrointestinal disorders.

10. Sugar Cravings

Gut bacteria secrete proteins resembling the hunger-regulating hormones leptin and ghrelin. These bacteria have an impact on appetite and mood.

Consuming nutritious foods nourishes beneficial microbes, increasing the propensity to consume healthy food. Conversely, frequently consuming sugary and refined foods nourishes bacteria that thrive on unhealthy or junk food, raising the desire for these foods. This explains why some people are drawn to unhealthy food and sugar cravings, while others are drawn to wholesome food.

If you experience any of these symptoms, only a doctor can determine whether they are due to a digestive system issue or something else. An experienced gastroenterologist or surgeon conducts tests to assess overall health and the intestinal environment, while a naturopath can restore digestive harmony by testing for food sensitivities, prescribing a specific diet, and identifying digestive issues.

Improving Gut Health: Mastering Your F-Goals

Is there no way to restore balance to the microbiome if it is vital to our well-being? Yes, they are.

Dr. Will Bulsiewicz, the author of “Fiber Fuelled,” a renowned gastroenterologist, gave a new idea about optimizing gut health via foods.

The abbreviation F-GOALS  stands for: 

  • F: Fruit and fermented foods;
  • G: greens and grains;
  • O: omega-3;
  • A: aromatics;
  • L: legumes;
  • S: seaweed, sulforaphane, and ‘shrooms.

Fruits And Fermented Foods

A balanced diet is incomplete without fruits and fermented foods, which contribute to digestive health and general well-being in their own special ways.

Fruits   provide fiber, anti-inflammatory minerals, and phytochemicals including vitamin C, flavonols, phenolic acids, and anthocyanins that promote intestinal health. Researchers at Cornell University found that people whose diets included a variety of fruits had higher levels of antioxidants. In another research, high-fruit diet is associated with an increase in the diversity of gut bacteria and the amount of beneficial bacteria, such as Bifidobacterium and Lactobacillus, both of which are indicators of a healthy gut.

Because fermentation is such a great way to keep food fresh for a long time, it is a part of the culinary traditions of nearly every civilization on the planet. Sauerkraut, kimchi, and pickles are examples of fermented foods that he said would help people’s guts. In his talk, Dr. Bulsiewicz referenced a research conducted in 2021 by the Stanford School of Medicine. The participants in the study ate fermented foods for 10 weeks, and the results showed that their gut microbiome had more variety of bacteria.

If you’re looking for a caffeine substitute, Dr. B suggests having a cup of miso instead of coffee in the afternoon.

Greens & Grains

Everyone knows that eating more leafy greens is good for you. 

Grains can be regarded as the bedrock of a healthy digestive tract owing to their exceptionally high fiber content.

According to Dr. B, eating whole grains is crucial for maintaining a healthy digestive system and you should cut out refined foods like white rice and processed bread. He offered evidence to support this. Whole grain eating was shown to have the most significant anti-inflammatory impact on the body, according to one specific ten-year study of dietary patterns that analyzed 37 different food categories. Those who cut off whole grains gained 12%.

So put a stop to your carbohydrate crusade and chow down on that warm, freshly baked sourdough; the research is in: healthy grains reduce inflammation.

Omega-3 Fats

Human and animal studies have shown that omega-3s can lower the risk of mental problems and enhance the beneficial bacteria in the gut. Even according to new research, Omega-3 may have anti-inflammatory and bacterial regulatory properties. But these omega-3 and omega-6 fatty acids are essential, yet your body cannot produce them.

The best approach to obtaining extra Omega-3 is by eating more seeds. Seeds are fantastic for scattering in salad dressings or oatmeal or providing texture. Dr. B recommends eating flax, chia, and hemp seeds and for omega-6 almonds, walnuts and seafood are best every day.

Aromatics

Dr. B recommends adding food items such as onions, leeks, and garlic to improve the gut health. These aromatics include the anti-viral, anti-fungal, and anti-parasitic enzyme allianase. A 2022 review in the International Journal of Molecular Sciences highlights onions as prebiotics that improve gut flora and treat conditions like diarrhea, osteoporosis, atherosclerosis, gastrointestinal disorders, cardiovascular disease, and Type 2 diabetes.

The catch is that we have to stop slicing the veggies before we can activate this enzyme. “Chop and Stop” is what Dr. B refers to this technique as. Before adding chopped garlic or onion, wait 10 minutes.

Legumes

“Legumes are the top superfood,” stated Dr. Bulsiewicz. They are economical and beneficial for you. Their high fiber content provides an additional basis for a healthy gut. They are an excellent way to get the protein, fiber, vitamins, and minerals your body needs. Additionally, they include prebiotics, which are nutrients that good bacteria in our stomach need to perform well. This means that they can help keep your microbiome, which consists of trillions of bacteria, in good shape.

So, why not try a bean and grain combination, such as brown rice and a variety of legumes? Making a full-length protein is possible with this method.

Sulforaphane

Although it may be difficult to pronounce, research has shown that this substance promotes the growth of beneficial bacteria and helps to bring intestinal harmony back into balance. Where can one get it? Only members of the cruciferous family, which includes cabbage, Brussels sprouts, broccoli, and cauliflower, contain the unique sulforaphane.

Making dietary changes to promote healthy gut flora is something you can do at any age. According to Nutrient research, your microbiome might undergo positive or negative changes in as little as one day when you go from a plant-based to an animal-based diet or vice versa.

Here are a few other ways of lifestyle modifications that might help your gut health:

1. Reduce Stress

Gut health is only one of several areas of health that might benefit from stress management.

Although it’s hard to eliminate stress from your life completely, you may take a few minutes out of your day to engage in activities that help you relax and unwind. Progressive muscular relaxation, deep breathing exercises, and meditation are some methods for managing stress. You may also lower your stress levels by exercising frequently, getting enough sleep, and eating healthily.

2.Get Enough Sleep

Like the rest of the body, the digestive system heals and replenishes itself while we sleep. However, severe impacts on gut health may result from little or poor quality sleep, which can lead to more sleep problems. It should be a top priority to get the recommended seven to nine hours of sleep every night, as the National Sleep Foundation states.

Incorporating these practices into your routine can help your gut flora flourish, which will have a positive effect on your overall health.

3. Limiting Antibiotic Intake

Antibiotics and proton pump inhibitors (PPIs) are two examples of essential treatments that, when taken in excess, can have harmful effects on the digestive system.
You should only take antibiotics if your doctor prescribes them. One possible link between antibiotic resistance and weight gain is eliminating beneficial and harmful microorganisms from the gut microbiome.

4. Keep Good Water Intake.

If you want to help your stomach heal faster, drink two liters of filtered water daily. Water promotes peristalsis and aids in the evacuation of waste and waste products.

You can also keep your gut lining and intestinal mucosa hydrated by trying herbal teas or water with a squeeze of lemon instead of sugary sodas and fruit juices. A European Journal of Pharmacology study found that green tea helped reduce gastrointestinal issues, such as constipation and poor motility.

6. Have Pre and Probiotics

 Recent research also focuses on probiotics potentially improving immunity and changing the gut microbiome’s composition. Probiotics also alleviate diarrhea, strengthen the immune system, maintain healthy skin and hearts, and aid in preventing chronic diseases by balancing the microorganisms in your stomach. It also houses the most beneficial gut bacteria, Lactobacillus and Bifidobacterium.

Sources of probiotics include (Beneficial bacteria in our gut that can also be found in food);

  • Unpasturised/raw kimchi (not heat treated)
  • Yoghurt with active/live cultures
  • Sauerkraut, Kimchi, and Pickled Vegetables
  • Tempeh and Miso

At the same time, the other types of foods are prebiotics. They are fibers that nourish the gut flora and consuming fibers promotes the growth and flourishing of probiotics in the digestive tract.  Sources of prebiotics include (Nutrients found in food which feed the bacteria in our gut) ;

  • asparagus
  • oats
  • apples/ banana
  • cocoa
  • onions/ garlics
  • beans/artichokes

The importance of gut health to general well-being is frequently underappreciated, according to Dr. B, who claims that we are only as good as our digestive systems. We need to take care of our bacteria to nourish the gut. The potential side effects of medicine and unhealthy eating habits must also be considered.

Despite all this, a plant-based diet is really all about eating a wide range of foods. Therefore, be accepting of others and eat a plant-based diet rich in fiber that contains plenty of fruits, nuts, seeds, veggies, and whole grains.
