Fiber Has Many Benefits

June is National Fruits and Vegetables Month and we all know that fruits and vegetables are great for our health. They contain many different vitamins, minerals and other nutrients to keep us healthy. One particular nutrient found abundantly in fruits and vegetables boasts many health benefits. However, most of us likely aren’t getting enough of it in our diet. That nutrient is fiber! The 2020 Dietary Guidelines for Americans listed fiber as a nutrient of concern because many don't get enough. So, what is fiber, why is it so important and are you getting enough?

Fiber is a type of carbohydrate found in plant-based foods that is not digested in the body. Because of this, fiber provides a plethora of health benefits. Whether you are trying to lose weight, manage your blood sugars, or working to improve your digestive health, fiber is beneficial to everyone. Foods high in fiber tend to be more filling and will keep you full longer, which can be helpful if you are trying to lose weight.

For those with diabetes, people often think they should avoid fruits due to their sugar content. While fruits do contain naturally-occurring sugar, they also have lots of fiber. That fiber can help improve blood sugar levels and prevent spikes and drops in blood sugars, resulting in more stable blood sugar levels.

Another great benefit of fiber is that it can help lower your cholesterol levels by getting rid of extra cholesterol in your body. It can also help regulate bowel function, and a diet high in fiber may reduce your risk of developing colorectal cancer.

So how do you know if you are getting enough fiber in your diet? The recommended daily fiber intake is at least 21-25 grams per day for women and 30-38 grams per day for men. Fiber content is listed on the Nutrition Facts Label making it easy to see how much fiber you are getting in your diet. Look for high-fiber foods that contain at least 5 grams of fiber per serving. If you aren't getting enough in your diet, it is recommended to increase your intake gradually.

Fruits and vegetables are only a couple of examples of high-fiber foods. Fiber is abundant in whole grains, beans and legumes as well. Summer is a great time to incorporate some new fruits and vegetables into your and your family's diets. Head to the Harvest Market to pick out some new fresh produce to help you reach your fiber goal!
