We know, we have been talking about fruits and vegetables a lot lately.
Today we are going to dig into five benefits of adding additional fruits and veggies in on the daily.
Here’s your warning: In this blog, we will nerd out on some of the science behind the benefits of eating more fruits and vegetables. Let's get geeky!
1- Fiber
This is a topic which always seems to come up in magazine articles or social media posts as being something so important. But they never seem to fully explain why we should be adding it in.
Here is the lowdown on fiber-
Fiber is essentially the indigestible part of your food. It is able to survive digestion in the small intestine and make it to your large intestine. There are two kinds of fiber, each both have their own jobs.
Insoluble
This type of fiber increases stool bulk. Think reduced transit time and decreased constipation. Because of these two benefits, insoluble fiber not only helps reduce constipation but also reduces risk for colon cancer. Cutting down on transit time means shorter exposure to possible consumed carcinogens in your intestines and colon therefore reducing risk for colon cancer.
Soluble
Soluble fiber creates a semi gel-like texture in your stool. This gel-like texture is helpful in collecting substances and excreting them. One of the benefits of consuming this type of fiber is helping to lower your cholesterol levels. I’m sure you all have heard of bile, well in your digestive tract there are bile acids. These bile acids which come from bile are made using cholesterol. When your stool has the gel-like texture these bile acids bind to your stool and you excrete them. Because you are excreting them, your body will need to make more. In making these bile acids, your body has to pull from it’s circulating cholesterol to create these acids. Therefore, if you are eating a diet high in soluble fiber your body will be making these bile acids at a higher rate and therefore lowering your cholesterol levels.
Another benefit that works essentially in the same way as the bile acids, is helping to prevent a spike in blood glucose levels. Because of the gel-like texture of the stool, it is able to slow the absorption of glucose in your digestive system.
Fruits and vegetables, along with other whole foods, are phenomenal sources of both kinds of fiber.
