Common Kinds And Sources Of Probiotics
Many probiotics are naturally living in the body, they are also found in fermented products such as yogurt, some cheeses, and pickled vegetables. The common species are Bifidobacteria , Lactobacillus . The common strains include B. animalis, B.breve, B. lactis, B. longum, L. acidophilus, and L. reuteri .
Type Ii Diabetes And Glycemic Control
There are many theories surrounding the relationship between fiber intake and type II diabetes. For example, regularly consuming the recommended amount of fiber has the potential to attenuate glucose absorption rate, prevent weight gain, and increase the load of beneficial nutrients and antioxidants in the diet, all of which may help prevent diabetes.
Numerous large-scale cohort studies support a strong inverse relationship between dietary fiber consumption and development of type II diabetes. A multi-ethnic cohort followed 75,000 people for 14 years. People who ate more than 15 g of fiber per day had significantly lower diabetes risk . People who ate high amounts of insoluble fiber or cereal fiber had less type II diabetes risk than people who had lower intakes while soluble fiber intake was not associated with diabetes risk .
Intervention studies provide inconsistent results. For instance, compared to a 5-week control diet, 5 weeks of oat beta-glucan significantly reduced postprandial glucose and insulin responses, while 5 weeks of barley beta-glucan did not . Nazare et al. found significant reductions in glucose and insulin when fiber was added to a standard breakfast. Many acute intervention trials fail to find a relationship between fiber intake and post-prandial glucose response .
First Lets Review What Dietary Fibre Is
Fibre describes plant material that your body cannot digest or absorb. Unlike fats, proteins or carbohydrates which your body breaks down and absorbs, fibres pass through and remain relatively intact through your stomach, small intestine and colon on its way out of your body. In other words, fibre binds with your bodys waste products, helping it move through the proper channels!
Its extremely important to make sure you get enough fibre in your diet. The best way to incorporate fibre into your diet is to make sure youre consuming a high volume of plant-based foods, like fruits, veggies and whole grains. There are two types of fibre, soluble and insoluble, and both have different benefits for gut health. Insoluble fibre helps keep bowel movements regular. Soluble fibre dissolves in water to form a gel and helps to either bulk up loose stools, or soften firm stools. Soluble fibre can also help to lower blood cholesterol and control blood sugars.
Below is a quick chart to show you some foods that contain both soluble and insoluble fibres:
|Vegetables e.g. cauliflower, broccoli, green beans, spinach, kale Fruits, especially fruit skins|

Key Takeaways: Prebiotic Vs Probiotic
- Both prebiotics and probiotics serve gut health.
- Prebiotics are plant fibers that naturally ferment in the colon, acting as food for beneficial or “good” bacteria.
- Probiotic-rich foods include live culture dairy products like yogurt or milk
- Consuming prebiotic foods and prebiotic supplements may decrease the risk of cardiovascular disease, certain types of cancer, improve the immune system, reduce inflammation, and spur weight loss.

Is Metamucil A Probiotic
Metamucil contains PSYLLIUM HUSK and different flavored options contain varying amounts of sugar ranging from 4 up to 7 grams. They do however have some sugar-free options available in both capsule & powder form.
PSYLLIUM HUSK is not a type of bacteria and therefore Metamucil is not a probiotic in any way at all. Interestingly however the side effects of Metamucil include cramping, bloating, and changes in stool consistency.

World Health Organization/food And Agriculture Organization
Recognizing the possible beneficial effect of prebiotics in food, the Food and Agriculture Organization of the United Nations convened a Technical meeting to start work on the evaluation of the functional and health properties of prebiotics . A prebiotic is defined by the FAO as a non-viable food component that confers a health benefit on the host associated with modulation of the microbiota. At the Technical meeting, a group of international experts agreed on guidelines and recommended criteria and methodology for systematically approaching the evaluation of prebiotics for safe use in food. It was recommended that a full expert consultation be convened under the auspices of FAO.
Synbiotics Blend Both Pre
Dr. Cresci is actively studying synbiotics, which combine aprebiotic and a probiotic.
A probiotic in a capsule may not survive while sitting onthe grocery store shelf or passing through the intestinal tract, she says.But when you combine it with its food source, the prebiotic, it has a muchbetter shot at staying viable until it reaches the part of the gut where itwill ultimately live.
Dr. Cresci recommends people get their probiotics andprebiotics from a healthy diet, but if you need to take a supplement, sherecommends choosing a:
- Product that has a seal of approval from testingagencies such as Consumer Reports or Consumer Labs.
- Probiotic capsule packaged with inulin or otherprebiotics.
- Probiotic in spore form, which can survive onthe shelf or in the digestive tract.

Obesity Satiety And Weight Loss
Studies of lean and obese mice suggest that the gut microbiota affects energy balance by influencing the efficiency of calorie harvest from the diet, and how this harvested energy is utilized and stored . To address how host genotype, environmental exposures, and host adiposity influence the gut microbiome, the fecal microbial communities of adult female monozygotic and dizygotic twin pairs concordant for leanness or obesity, and their mothers were characterized . Obesity was associated with phylum-level changes in the microbiota, reduced bacterial diversity, and altered representation of genes and metabolic pathways.
Health Benefits Of Fiber
Evidence-based reviews use an accepted hierarchy to examine the body of evidence for a clinical nutrition question . Typically double-blind, randomized, controlled trials are the gold standard for clinical evidence. Well-conducted intervention studies in target populations are also well regarded in evidence-based reviews. Prospective, cohort epidemiological studies provide important support for diet and disease relationships. Lower level knowledge examples are clinical cases and expert opinion.
Animal studies and in vitro studies provide important clues for mechanisms for a relationship between disease and dietary exposure, but are typically not included in evidence-based reviews. In dietary fiber research, much of our information on fermentation of fibers is based on in vitro models of fermentation. These data help us compare fibers, but need to be tested in human clinical trials to support their use in clinical nutrition.

The Different Ways That Prebiotics And Fiber Affect The Gut Microbiota
This infographic from the International Scientific Association for Probiotics and Prebiotics offers a helpful comparison between prebiotics and fiber while describing the extent to which each affects health and the gut microbiota.
Fiber is a key overlooked nutrient in the diets of many. Although some fiber cannot be digested by humans, it can be broken down by the microbes in our gut â a community of bacteria called the gut microbiota. Like fiber, prebiotics also act as food for beneficial microbes in the gut, and many current prebiotics are actually considered to be a form of soluble dietary fiber. The similarities between fiber and prebiotics often lead to confusion on how to differentiate the two. Luckily, this infographic from the International Scientific Association for Probiotics and Prebiotics offers a helpful comparison between prebiotics and fiber while describing the extent to which each affects health and the gut microbiota.
Most fiber is non-digestible carbohydrate derived from plants. For example, apples, black beans, and broccoli are all excellent sources of fiber. Beyond promoting regular bowel movements, adequate fiber consumption improves blood levels of lipids and glucose, while keeping us fuller for longer. Some fiber even has a low to moderate effect on our gut microbiota.
For more information on the differences between prebiotics and fiber, take a look at the infographic here.
How Much Should You Be Getting
While there isnt a recommended daily amount of prebiotics to consume, Health Canada recommends 25 grams of fibre per day for women and 38 grams of fibre per day for men.4
According to Bélanger et al.5 the actual intakes of dietary fibre for Canadian men is 19.1 grams per day and for women is 15.6 grams per day. So most Canadians are only getting about half of the recommended fibre intake.
We know it can be tough.Next time you are at the grocery store, spend time exploring the produce section, its the largest section in the store. Fill your cart with lots of colourful fruits, vegetables and try to buy in season. That way you can reach your daily dose of 25 to 38 grams, without even having to think about it!

Gut Health Starts With Prebiotics
You can buy prebiotic supplements, but you dont need themif you eat the foods that fortify the army of friendly bacteria in yourintestines, Dr. Cresci explains.
She recommends these microbiota-loving foods:
- Fiber-rich foods: Fruits, vegetables andwhole grains.
- Potatoes: Ideally, a boiled and cooled potato,since the starch is more resistant to digestion.
- Bananas: Green, less-ripe bananas arerich in resistant starch.
- Jerusalem artichokes: A root vegetablerich in the prebiotic inulin.
Do I Need To Take A Probiotic Every Day
Most experts recommend taking a probiotic supplement daily, especially if youre taking antibiotics or other medications that can disrupt the balance of good and bad bacteria in your gut. Probiotics can also be helpful if youre traveling or have a gastrointestinal illness.
If you have a specific health concern, such as irritable bowel syndrome , Crohns disease, or ulcerative colitis, you may need to take a higher dose of probiotics or take them more often. Consult with your doctor to see if probiotics are right for you.

What Are The Main Differences Between A Prebiotic And A Probiotic
Here are the critical differences:
- Prebiotics are a type of fiber that feeds healthy bacteria in the gut.
- Probiotics are live bacteria, like those found in milk, yogurt, and active culture cheeses.
- Prebiotics are resistant to heat and stomach acid.
- Probiotics are sensitive to heat and stomach acid.
- Prebiotics may cause digestive distress if added too quickly or for those with gastrointestinal disease.
- Probiotics in very high doses may cause bloating, increase thirst, trigger a headache, and rarely they may cause an infection in people with a suppressed immune system.
Current Understanding Of Fiber
Fiber is defined differently throughout the world. Some definitions are based on analytical methods for isolating fiber, while there is a move to define fiber on a physiological basis. Traditonally, fiber was measured as chemical components, such as cellulose, hemicellulose, pectin, and lignin, the only noncarbohydrate component of fiber. Currently the United States relies on an analytical approach to determine what is or is not considered fiber for purposes of listing fiber content on food labels. In 2001 the Institute of Medicine developed the following set of working definitions for fiber in the food supply :
Dietary fiber consists of nondigestible carbohydrates and lignin that are intrinsic and intact in plants.
Functional fiber consists of isolated, nondigestible carbohydrates that have beneficial physiological effects in humans.
These definitions recognize the diversity of nondigestible carbohydrates in the food supply. This definition has yet to be formally adopted by the U.S. Food and Drug Administration , but it includes plant, animal, and manufactured fiber sources that exhibit beneficial physiological effects in humans.
The Nutrition Facts label is based on 25 g of fiber recommended daily for a 2000 calorie diet. Americans typically consume about half of the recommended amounts of fiber each day . Flours, grains, and potatoes are the most popular sources of fiber in the American diet while fruits, legumes, and nuts are the least popular sources .

Which Foods Are Probiotic
There are also many probiotic foods that naturally contain helpful bacteria, such as yogurt.
A high quality, plain yogurt with live cultures can be a fantastic addition to your diet if you want to add beneficial bacteria.
Fermented foods are another great option, as they contain beneficial bacteria that thrive on the naturally occurring sugar or fiber in the food.
Examples of fermented foods include:
- other pickled vegetables
If youre going to eat fermented foods for their probiotic benefits, make sure theyre not pasteurized, as this process kills the bacteria.
Some of those foods can also be considered synbiotic, because they contain both beneficial bacteria and a prebiotic source of fiber for the bacteria to feed on.
Some examples of synbiotic foods are cheese, kefir, and sauerkraut.
Probiotic foods naturally contain helpful bacteria. Many of these foods can be made at home or purchased at a grocery store.
Gut Bacteria: The Bffs You Never Knew You Had
In human intestines, there are many strains of two mainspecies of friendly bacteria, Lactobacillus and Bifidobacterium, Dr. Crescisays. Probiotics and prebiotics both help those friendly bacteria, but indifferent ways:
These are live microorganisms isolated from humans and thencultured in a lab to be used as a supplement. When we ingest them , they survive in the gut and provide benefits to uslike the good bacteria that we naturally have.
This is a food source for the friendly bacteria in your intestinal tract. Our digestive system cant break down prebiotics, so they survive the journey through the digestive tract. They eventually reach the part of the colon where the friendly bacteria hang out. The bacteria have the chops to break down the prebiotics into nutrition that helps them grow and thrive.

Taking Fiber For Weight Loss
1 Cup Of Boiled Broccoli Has 5g Of Fiber.
According t this 2015 study in the Annals of Internal Medicine suggested that increased fiber intake could lead to weight loss in adults who were obese and so they set out to test this fiber weight loss theory in a clinical setting.
The study had 240 participants with metabolic syndrome and it was a randomized placebo-controlled study. Half were asked to eat a high-fiber diet for 12-months and another group followed a standard American Heart Association recommended diet.
Some participants dropped out of the study before the end but the results showed that there wasn’t much difference in weight loss between the AHA and Fiber group. If you are looking to add fiber into your diet for weight loss there may be better solutions as this study suggested fiber isn’t great for weight loss.
