The fiber gap

It is generally accepted among dieticians and nutritionists that women should consume 25g of fiber per day and men 38g. This fiber can be soluble (able to be dissolved in a liquid) or insoluble, with the soluble component making up roughly 25% of the total fiber intake (6.5g and 9.5g for women and men respectively). It is also generally accepted that while most people consume too many carbohydrates, fat and protein in their diet, at least 80% of adults in the developed world consume about 50% of the fiber they should be getting in their diet. This translates into a soluble fiber gap of at least 3g for women and 5g for men.

Why should we care?

There is a growing body of research supporting a strong correlation between the intake of soluble fibers (otherwise known as prebiotics) and beneficial health effects. These include digestive balance and regularity, a healthy immune system, weight management, blood sugar management, healthy cholesterol levels and mineral absorption for bone health. Other research has seen a correlation between low soluble fiber intake, gastrointestinal inflammation, and an increased risk of developing a number of chronic diseases, an even more interesting observation given that over 50% of adults in some parts of the world currently suffer from one or more chronic diseases.

The wonderful microbiome

The microbiome (or more correctly the microbiota when talking about the microbes living in our gut) is sometimes referred to as the newest human organ or second brain. It is the 100 trillion bacteria, viruses and fungi that live in our gut and on our skin, bacteria alone outnumbering our own cells by at least 3 to 1 according to the latest research. While our understanding of the microbiome is still very limited, there is a general consensus among scientists that the microbiome plays a key role in maintaining our health. When the gut microbiome is in a state of in-balance or dysbiosis, there is an increased presence of bad or pathogenic bacteria and lack of good bacteria such as lactobacillus and bifidobacteria.

What are probiotics & prebiotics?

Understanding the difference between prebiotics and probiotics can sometimes be confusing. Probiotics are bacteria and can be found naturally in your gut (as described above), as well as in food products such as yogurts or in supplements. Prebiotics (or soluble fibers) are indigestible carbohydrates that are not food for us but rather food for the good probiotic bacteria in our gut. They can be found naturally in vegetables, fruits, grains and seeds. It is believed that when we do not eat enough soluble fibers that we create a state of dysbiosis in our gut. Thus, one could suggest the best way to correct this state is to first eat soluble fibers and then add a probiotic to get an extra boost (if necessary).

It is not so simple

The best way to get soluble fibers into each of us and fill this fiber gap is to have a strong plant based diet. However, for most of us, this is a challenge for several reasons. Firstly, our eating habits and lifestyles prevent us from doing so. For example, to get the equivalent of 5g of soluble fiber (the fiber gap for men), one would have to eat 7 green bananas, 15 slices of whole grain bread or drink 26 glasses of orange juice. Most of us simply do not move enough every day to process these extra 550-1450 calories. Secondly, the current generation of prebiotic or soluble fiber supplements are not optimal. Taking too much or the wrong fiber may cause discomfort, while taking too little or the wrong fiber may have no effect at all. Lastly and most importantly, each of us is different in terms of age, gender, diet, medicine use, and lifestyle, therefore our gut microbiomes are all different. Moreover, our gut microbiomes are constantly changing. So, what is the solution?
