In the last PhytoFit, LLC blog, “Do Ya’ Think I’m Sexy, Do You Really Need Me?” we discussed our best friend…fiber! Although many or you may have laughed and thought I had finally stepped over the edge, I explained why ALL of us should write a love song about FIBER!
Some of you may ask, “Why is fiber so important?” Going back in history, dating back to ca. 460 BC – ca. 370 BC, Hippocrates, the father of modern medicine, believed, “All disease begins in the gut.” As we learn more and more about our gut microbiome, we know that fiber feeds our gut microbes, improves the healthy gut bacteria, and literally provides an almost systemic effect on the whole body.
A study published in the journal Nutrient outlined the health benefits of fiber, which include:
With all of these health-promoting benefits, it's hard to believe that 95% of Americans fall short of their dietary fiber requirements. Yes, only 5 out of every 100 people get enough daily fiber! In his book, The Fiber Fueled Cookbook, Dr. Will Bulsiewicz states, “…32% of our calories come from animal foods; 57% come from process plant foods; and only 11% from whole grains, beans, fruits, vegetables, and nuts. Among that 11%, the number one item is potatoes from French fries and chips.” Consequently, many people may believe that potatoes from French fries and chips are a good source of fiber.
So, just how much fiber is enough? On average, most Americans consume 10 to 15 grams of fiber every day. There are rural populations that consume significantly more fiber resulting in remarkable health. In one of his more recent videos, Dr. Michael Greger states, “…in populations where many of our deadliest diseases are practically unknown, such as rural China and rural Africa, they’re eating huge amounts of whole plant foods, up to a 100 grams of fiber a day or more….” In his book, “How Not to Die,” Greger states, “Humans evolved eating large amounts of fiber, likely in excess of 100 grams daily.”
The Physicians Committee for Responsible Medicine recommends a minimum of 40 grams of fiber every day. Increasing fiber intake by only 7 grams a day may be associated with a 7 percent risk reduction for a stroke. (How Not to Die) This is as easy as a bowl of oatmeal with berries or just one serving of beans.
Increasing fiber by an additional 7 grams a day will result in a 9% lower risk for cardiovascular disease. That’s just like some rice and beans or a few servings of fruits and vegetables.
Adding 6 grams of fiber a day reduces breast cancer risks by 62% compared to women who consumed 4 grams or less. This could be achieved with a snack of 1 medium apple with a 1 ounce (1/4 of a cup) serving or walnuts.
How do we go from 10 grams to 40 grams a day to improve our health? First, realize you should start slowly. Gradually increasing your current fiber intake by 5 grams a day is a great start. Maintain that level every day for a week. The following week add an additional 5 grams, which is 10 grams more than your starting point. Each subsequent week add 5 grams until you reach your goal of 40+ grams of fiber per day. This will help you reach your fiber goal without the gastrointestinal gas or bloat.
In Dr. Greger’s book, How Not to Die, he recommends the Daily Dozen.
Dr. Greger's Daily Dozen: (recommended number of servings per day)
1. Beans: 3/day
2. Berries: 1/day
3. Fruit: 3/day
4. Cruciferous vegetable: 1/day
5. Green leafy vegetables: 2/day
6. Other vegetables: 2/3day
7. Flaxseeds: 1 tablespoon/day
8. Nuts/seeds: 1 ounce/day
9. Spices: 1/day
10. Whole grains: 3/day
11. Water: 6/day
12. Exercise: 45 minutes/day
Here is an example of what the Daily Dozen would look like using the free app from MyFitnessPal. (There are other apps to track daily food consumption, macronutrients and fiber.) Note that a total 61 grams was consumed on this day.
