The Fiber guide: How to get more fiber and 30 high fiber foods to try

Chris, what is the most underrated nutrient?  

So, glad you asked.  

I think fiber is the most underrated nutrient; on average, most Americans are horrible at getting enough in their diet.  

When I talk about fiber, I don’t mean the day-old bran muffin you accidentally grabbed at Starbucks. Sorry, that happened to you; blueberry muffins taste way better. 

Let’s talk about fiber, why you need it, and 30 different high-fiber foods you can try.  

What Is Fiber? 

If we take a minute to get sciencey, there are specific types of carbohydrates the body can more easily turn into sugar molecules, called glucose. Fiber does not break down into sugar molecules and therefore passes through the body undigested. 

You can call fiber “nature’s broom.” 

There are two types of fiber in fruits, vegetables, whole grains, and legumes.  

Soluble or fermentable fibers are fermented in the colon. 

Insoluble fibers have bulking action and ferment for a shorter period. 

Soluble fibers will dissolve in water (plant pectins), and insoluble fiber will not dissolve in water (plant cellulose and hemicellulose).  

Both types of fiber take more time for the body to digest properly, which is why adding fiber to your diet can be helpful for hunger and fullness between meals.  

Not to mention most high-fiber foods are unprocessed, low calorie, and nutrient-dense. 

As the body digests soluble fiber, it creates a gel-like substance that might improve digestion. Sources of soluble fiber are oats, peas, beans, apples, citrus fruits, carrots, barley, and psyllium.

Insoluble fiber soaks up water which helps to make it easier to poop. Sources of soluble fiber are beans, whole wheat or bran products, green beans, potatoes, cauliflower, and nuts.

Consuming enough fiber has been shown to reduce the risk of coronary heart disease, stroke, hypertension, diabetes, obesity, and certain gastrointestinal diseases.

How Much Fiber Should You Have? 

The adage that too much of anything can’t be good applies to fiber. 

When someone starts overconsuming fiber to become “healthy” after watching a Tiktok video on creating the ultimate fiber drink, they usually end up bloated, gassy, and constipated. Ironic, huh? 

Getting more fiber in your diet is good, but going from zero to 150 isn’t your best bet.  

So, my eager beaver friend, I would try to stick to these dietary guidelines:

Adult Men: 36 g/day 

Adult Women: 28g/day 

Most Americans consume less than half of the recommended amount of fiber.  

Earlier I made fun of the person drinking the Tiktok fiber bomb beverage, and now I want to apologize.  They are just trying to get more fiber in their diet.

You can drink a fiber supplement if you have difficulty hitting the daily recommended amount; however, the phytonutrients & micronutrients are usually missing from those supplements.

Don’t worry.

May you live a long life full of many poops. 

I hope you will consider the many health benefits of having fiber in your diet.  

There are so many diets that people try to follow; one, in particular, suggests removing fiber altogether from your diet.  

If you follow that diet, I suggest you consider the long-term effects and ask yourself if you genuinely enjoy having horrible poops.  

If you answered yes, this article was a complete waste of your time. 

If you answered no, I think you wisely spent your time. 😉
