Let’s face it, constipation happens. We don’t like to talk about it, but if you’ve ever been constipated it is certainly uncomfortable and your mission becomes to fix it…stat!

The Difference between Soluble and Insoluble Fiber

Fiber comes in two types, soluble and insoluble. Soluble fiber dissolves in water and helps regulate cholesterol and blood sugar. Soluble fiber is commonly found in beans and fruits.

Insoluble fiber doesn’t dissolve in water. It acts as a scrubber in your digestive tract. Insoluble fiber is found in vegetables and whole grains.

How Much and What?

A diet rich in both types of fiber is crucial. According to the Academy of Nutrition and Dietetics, men under 50 need 38 grams of fiber each day and women need 25 grams. Adults over 50 require less fiber (30 grams for guys and 21 grams for ladies) due to decreased food consumption. To understand what that amount looks like, check out the sample meal below, which contains 37 grams of fiber. The key is eating a couple fiber-containing foods at every meal, particularly vegetables, fruit, nuts, legumes, beans and whole grains. As you can see, meats, dairy, and eggs do not have protein. This is why eating a variety of foods and adding many different colored foods is an important and beneficial rule of thumb.

A Real Life Example of Enough Daily Fiber

Water To Keep Things Moving

While focusing on fiber, don’t forget water, and lots of it! If you’re eating plenty of high-fiber foods but not getting enough fluid to help flush it through your system, you can make matters worse. Drink at least 8 to 10 glasses of decaffeinated fluids every day to assist in keeping your stools soft. Have a water bottle available wherever you are. A large water bottle that holds a lot of water may be more convenient because you don’t have to keep refilling it. My husband recently received this Klean Kanteen as a gift and now drinks about 2-3 bottles per day at work--all because it’s more convenient.

Sneaky Tips to Boost Your Fiber Intake

• Add flaxseeds to oats, smoothies, and yogurt. Flaxseeds assist with constipation as these have the action of lubricating the bowel. Two tablespoons will boost your daily fiber by 3.8 grams.

• Chia seeds have a whopping 5.5 grams of fiber per tablespoon.

• Coffee is an old-fashioned remedy that helps millions to avoid constipation. In fact, it is one of the main reasons people choose coffee in the morning. Coffee irritates the intestines a little and can stimulate bile flow from the liver. Avoid the fashionable cappuccinos and lattes. They are too strong, contain less water, which is bad, and they contain more caffeine, which is also worse and more irritating. If you use coffee, limit it to one cup of regular coffee daily.

• Another remedy you may consider is 1 teaspoon of apple cider vinegar mixed with 3 oz of water and juice from a lemon wedge (1 tsp of lemon juice). Do this before meals to help stimulate digestion. Also do upon rising in the morning to stimulate a bowel movement.

• Consider a potent Probiotic—something like ProBiota 12. Balancing and supporting beneficial bacteria in the digestive tract is critical for many functions: immune, digestive, neurological, dermatological and others. Take 2 capsules about 5-10 minutes after dinner.

• Consider a fiber supplement to add bulk to your stool, such as this one.

• Avoid refined carbohydrate foods, such as white sugar, white bread, white rice, white pasta, sugary cold cereal, and other poor quality, low-fiber, and highly processed foods.

• Stick to whole grain foods, such as 100% whole wheat bread, quinoa, oats, brown rice, wild rice, amaranth, and millet. To check out more whole grains, visit the Whole Grains Council website.

• Eat the fruit rather than drinking the juice. The peel and pulp are where the majority of the fiber is located. Whole fruit is more filling than juice, so don't cheat yourself.

• While spinach isn’t as high in fiber as other veggies, it can easily be sliced and snuck into many dishes without adding much taste or hassle. I add organic baby spinach to so many things, such as soup stock, eggs, smoothies, protein shakes, and pasta sauce.

• Everyone always thinks of vegetables, fruits, and whole grains when they think of high-fiber foods, but nuts are very impactful. As you can see from the example above, only ¼ cup provides 4 grams of fiber. Find a trail mix you like and include it regularly as a snack.

One final tip, don't forget exercise. Exercise most days of the week. It increases muscle activity and the speed which food travels through your intestines.

Bottom Line: If you're constipated, get really serious about boosting the fiber in your diet. Pack in the salads and fruit at a couple meals, beans, and whole grains--all in one day. Drink a lot of water, and if you do this everyday, you'll be regular in no time.

REDUCED STROKE RISK

A new meta-analysis of eight observational studies suggests another possible benefit for dietary fiber—reducing your danger of suffering a stroke.  British scientists reported in the journal Stroke that each additional seven grams of daily fiber intake was associated with a significant 7% lower risk of the two main types of strokes (ischemic and hemorrhagic). 

Seven grams of fiber is about the equivalent of an extra serving of beans or two servings of fruit such as apples or oranges.

WHAT FOODS HAVE FIBER? 

Most people get their fiber from vegetables, fruit, legumes, beans, and whole grains (oatmeal, 100% whole wheat bread, etc.) 

FIBER SUPPLEMENT

It is definitely possible to get enough fiber from supplements.  The amount of fiber in a fiber supplement varies from brand to brand, but usually ranges from 6-10 grams per serving.  With that said, I suggest using a fiber supplement as just a way to top off your fiber intake in order to meet the daily recommendation.

WHAT’S THE DAILY FIBER RECOMMENDATION? 

Per the Institute of Medicine, here are the numbers:

Men over 50:  30 grams

Men under 50:  38 grams

Women over 50:  21 grams

Women under 50:  25 grams

SOLUBLE VS. INSOLUBLE FIBER

Soluble fiber forms a gel in the stomach and small intestine, slowing the rate of nutrient absorption and slowing gastric empting.  This effect increases your feeling of fullness and influences the overall amount of food eaten, resulting in lower levels of overweight.

Bacterial fermentation of soluble fibers in the large intestine produces short-chain fatty acids, which inhibit cholesterol synthesis by the liver, consequently lowering serum cholesterol levels.

Insoluble fiber adds bulk to our stool, preventing constipation and reducing risk of hemorrhoids. 

Insoluble fiber helps our gut bacteria, or gut flora, to grow.  Our gut bacteria are living organisms that eat sugars and fiber, and prevent bad bacteria from living in our gut and making us sick.  Insoluble fiber is a strong fiber that takes a lot longer for our gut bacteria to break down, which helps them grow and multiply.  

Bottom Line:

There are many reasons to eat your favorite high fiber foods everyday…not only reduced risk of gastrointestinal disorders and diverticular disease, but also better cholesterol levels and blood pressure, and reduced risk of stroke.
