Have you ever wondered, “Why fiber? Why does it matter to me, and how can I add more of it into my diet?” Fiber is critical to a healthy diet—and a healthy life. Fiber is only found in plants, and fiber content is especially high in beans and grains. It has zero calories. It slows down the conversion of food in your body from carbohydrate to sugar, which makes you feel full longer. Highly processed foods have very little fiber, while whole foods have more. You might have noticed that you feel stronger, happier, and more energized when you eat whole foods instead of processed foods. One fun fact is that usually foods with higher fiber content have a higher concentration of protein, too—a win-win for your body and your brain!
