Fiber Has a Big Impact on Overall Health

Fiber is found in a wide variety of foods we eat, and is important to our digestive and cardiovascular systems. It helps lower cholesterol, stabilize blood sugar, and control our weight. A recent study published in the January 2019 Lancet found that, when compared to those who ate less fiber, participants who consumed between 25 - 29 grams of fiber a day had 15 - 30 percent less risk of: cardiovascular-related mortality, coronary heart disease, stroke, type 2 diabetes, and colorectal cancer. WOW! Sounds to me like we need to make sure we find ways to include more fiber into our diet.

"The best way to ensure you are getting good fiber in your diet is to eat foods as close to their natural state as possible."

There are two types of fiber and both are beneficial for your health. Insoluble fiber is fiber that takes longer to break down and helps create the sensation of being full after eating. It is found in fruits and vegetables with skins, whole grains like brown rice, whole wheat, buckwheat, oatmeal, nuts, seeds and dried fruits. Soluble fiber adds bulk to our digestion and is found in legumes, oatmeal, barley, bananas, and applesauce, for example. Soluble Fiber can help lower total LDL cholesterol and stabilize blood sugar. 

It's Easy to Get More Fiber

Fruits, veggies, whole grains, beans, and lentils all contain fiber. The challenge is to eat these foods with as little processing as possible. When food is processed, even into something "healthy and whole" like granola bars or whole wheat pasta, it negatively impacts the fiber quality and content. The best way to ensure you are getting good fiber in your diet is to eat foods as close to their natural state as possible. 

As important as it is to add fiber to the diet, it's also important not to add too much fiber to your diet at one time to avoid gas, bloating, cramping and diarrhea. Add it slowly by making sure you're eating a plant-based food close to its natural state with every meal.  Also, choose recipes that include vegetables and use whole grains (which are naturally less processed).  Then add fresh fruit, close to the form in which it comes picked, for dessert.
