Eating more vegetables can help you lose weight. Besides having more vitamins and minerals than fast food or junk food, they also have more fiber. Currently, Americans only eat about 16 grams of fiber—the parts of plants that can’t be digested—per day. That’s way less than the 25 to 30 grams that’s recommended.
Fiber can also affect your gut microbiome ( bacteria in your intestines). The bacteria eats the fiber and become healthier. A high fiber or low fiber diet can affect the health of your intestine in more than one way.
