What is Fiber?

Fiber is a carbohydrate that is not digested by our body. We don't have enzymes to break down the fibrous components of plants, although chewing does help a bit. But overall, it moves through us undigested and whole.

There are two types, soluble and insoluble fiber. Soluble fiber becomes a gel like consistency when we eat it as it absorbs with water. Insoluble is more like roughage that moves through whole.

Why Do We Need Fiber?

Fiber is so important for our body. It impacts us both directly and indirectly. While many people think that fiber is there mainly for your digestive system, it does impact many other things as well.

What fiber does for your body

Soluble fiber helps lower cholesterol and control blood sugar and feeds healthy bacteria in the gut.

There is now newer research coming out that shows how fiber is the foundation for gut health. Gut health is being linked to many things, from digestion to mental health and moods.

Fiber helps lower cholesterol by decreasing the absorption of bad cholesterol and pulling some of it out of our system.

Also helps keep inflammation down by feeding bacteria in our gut and diversifying it. This keeps inflammation down both short term and long term, which helps prevent lifestyle diseases like heart disease, diabetes and also manage weight.

This can also help indirectly by preventing types of dementia and cancers.

Insoluble fiber helps to clear our toxins and carcinogens out of our body and pulls water into the large intestine and colon which helps you poop.

What Happens if You Don’t Get Enough Fiber?

Most of the population are not getting enough fiber, in fact more than 95% are not getting what they need. Women are supposed to get a minimum of 25 grams a day and men 38 grams. This is based on fiber's role in the prevention of heart disease.

When your body isn't getting enough fiber, it can't function

• Constipation
• Stomach pains
• Headaches
• Blood sugar swings
• Mood swings
• Craving carbohydrates
• Not feeling satisfied with meals
• Overeating leading to weight gain
• Not sleeping well

Sources of Fiber

Whole foods are the best source of getting fiber. You cannot get fiber in animal products. When making any change in your diet, especially with upping your fiber, make sure to up it slowly to minimize GI discomfort.

There are different types of fiber, so eating a variety of foods is important. Some foods that contain fiber are:

• Beans (lentils, black beans, pinto beans, etc)
• Leafy greens
• Whole grains (brown rice, farro, quinoa, buckwheat, etc)
• Chia seeds
• Flaxmeal

Also make sure to drink plenty of water when you are eating lots of fiber!

While supplements can also be helpful, using whole foods to get fiber is best because with supplements you aren't getting the other healing benefits like the phytonutrients that come with fiber.
