Should I try a high-fiber diet?
Having a high-fiber diet is crucial for maintaining the health of your heart, gut, and metabolism. Fiber, a type of carbohydrate, cannot be fully digested by the body, making it unique among other carbs. It plays various essential roles in the body, including providing food for the beneficial bacteria in your gut.
Your gut microbiome, which consists of trillions of microorganisms, has a significant impact on your overall health. Scientists at ZOE have identified 15 "good" gut bugs associated with positive health indicators and 15 "bad" gut bugs linked to poorer health.
This article delves into the benefits and risks of a high-fiber diet, as well as which foods to include in your diet.
ZOE understands that a one-size-fits-all approach to nutrition is ineffective. By taking the ZOE at-home test, you can discover the composition of the "good" and "bad" bugs in your gut and learn which foods promote the growth of beneficial bugs.
Additionally, ZOE will analyze your blood sugar and blood fat responses to provide personalized nutrition recommendations tailored to your body's unique needs.

Benefits of Fiber
There are two main types of fiber: soluble and insoluble. Soluble fiber dissolves in water, while insoluble fiber does not. Both types are vital for proper body function.
Gut Health
Studies suggest that fiber can enhance the composition of your gut microbiome, benefiting individuals with gastrointestinal disorders like irritable bowel syndrome (IBS) and inflammatory bowel disease.
Research has shown that fiber from whole grains is associated with higher levels of "good" bacteria such as Bifidobacterium and Lactobacillus, as well as lower levels of harmful bacteria like Escherichia coli (E. coli).
Digestion
Fiber aids in various stages of digestion, including nutrient breakdown, absorption, food transit time improvement, and stool formation.
Heart Health
High fiber intake has been linked to a reduced risk of heart disease and stroke by nearly 25%. Additionally, studies have shown that fiber can improve cholesterol levels and blood pressure in individuals with heart disease or high blood pressure.
Furthermore, a high fiber intake may decrease the risk of early death by 25%.
Fiber contributes to heart health by reducing the absorption of "bad" cholesterol and triglycerides and enhancing the elasticity of blood vessel walls.
Blood Sugar Control
Studies indicate that high-fiber diets play a crucial role in managing blood sugar levels by slowing the rate at which sugar enters the bloodstream, thus preventing spikes in blood sugar.
Fiber also reduces inflammation, improves blood fat levels, and decreases the risk of premature death by 45% in adults with diabetes.
Characteristics of a High-Fiber Diet
Experts recommend that women consume around 25 grams of fiber daily, while men should aim for about 35 grams.
However, the average adult in the United States only consumes approximately 16-18 grams of fiber per day, falling short of the recommended intake.
Increasing your fiber intake can be straightforward when you know which foods to incorporate into your diet. There are plenty of affordable, high-fiber options that are easy to include in your meals.
Here are some excellent sources of fiber:
Vegetables
Fruits
Grains
bulgur wheat (8 g per cup, cooked)
dark rye flour (7 g per quarter cup)
whole-wheat spaghetti (6 g per cup)
oats (4 g per half cup)
rye crackers (3 g per 2 slices)
wheat germ (2 g per 2 tablespoons)
Legumes
Nuts and Seeds
chia seeds (10 g per ounce)
sunflower seeds (3 g per tablespoon)
almond flour (3 g per quarter cup)
peanuts (2 g per tablespoon)

Fiber Supplements
While fiber supplements may seem convenient, research suggests that the fibers in supplements do not offer the same health advantages as a high-fiber diet. Moreover, you miss out on essential nutrients found in whole foods.

Tips for Adopting a High-Fiber Diet
Introducing more fiber into your diet can cause temporary mild discomfort as your body adjusts. Here are some strategies to minimize potential issues:
Gradually Increase Fiber Intake
Although increasing fiber intake offers numerous benefits, doing so too quickly can lead to gas, bloating, stomach cramps, diarrhea, constipation, nausea, or a feeling of fullness. To prevent these issues, slowly increase your fiber intake to allow your gut time to adapt.
Stay Hydrated
Both soluble and insoluble fiber require adequate water intake to function effectively. Ensure you drink plenty of water regularly to prevent constipation.
Consume a Variety of Plants
There are different subtypes of fiber within the two main groups. To reap the full range of fiber benefits, aim to eat a diverse selection of high-fiber plants.
Additionally, the bugs in your gut microbiome have varying fiber preferences. Consuming a variety of fiber sources increases the likelihood of nourishing the "good" bugs in your gut.
Risks of High-Fiber Diet
Rapidly increasing fiber intake can lead to temporary discomfort. Individuals with IBS and other gastrointestinal disorders should exercise caution when adding more fiber to their diets, as different types of IBS respond to distinct types of fiber. If you have a gastrointestinal disorder, consult a healthcare provider before making significant dietary changes.
Conclusion
In the long run, consuming more fiber has positive effects on your health. Fiber serves as food for the bugs in your gut microbiome and can enhance heart, metabolic, and gut health.
There is a wide range of healthy, high-fiber foods that can easily be incorporated into your diet. Transitioning to more vegetables instead of meat, dairy, or fatty foods like fried items is an excellent starting point.
While increasing fiber intake is generally beneficial, it is important to do so gradually to avoid uncomfortable symptoms such as bloating, gas, cramping, and constipation. Remember to stay hydrated and consume a diverse array of plants.
