It's important to understand that "carbohydrates" is a very broad category that includes things like fruits and vegetables, beans, grains, legumes, muffins, and Pop-Tarts. We can't categorize all of those things under one roof. The benefit of including good carbs in the diet is providing satiety and fiber (which is important for a healthy gastrointestinal tract) and allowing for steady change or rise in blood sugar. There's an abundance of data that shows that carbohydrates are beneficial to cardiovascular and metabolic health and can actually increase lifespan or longevity. So all carbs aren't bad, but I do think that we need to be mindful about how we incorporate them into our diet and focus on more nutritious carbohydrates that provide or have some nutritional value, as opposed to refined, processed carbohydrates that may be fun and tasty, but have no nutritional value.
