Why Vegetables Matter on Keto

While the ketogenic diet is often associated with high-fat foods, vegetables provide essential fibre, vitamins, and minerals. Research shows that very-low-carbohydrate diets can be nutritionally adequate when including non-starchy vegetables (Bueno et al., 2013). keto fibre sources are particularly important to maintain digestive health while keeping carbs low.
