Final answer:
A vegetarian diet is usually 1) higher in dietary fiber than an omnivorous diet.
Step-by-step explanation:
Vegetarian diets primarily consist of plant-based foods such as fruits, vegetables, whole grains, legumes, and nuts. These foods are naturally high in fiber, which is essential for a healthy digestive system. Fiber helps to regulate bowel movements, prevent constipation, and promote overall gut health. On the other hand, an omnivorous diet includes a variety of animal-based foods, which generally contain less fiber than plant-based foods.
By incorporating more fiber-rich foods into their diet, vegetarians can enjoy the benefits of improved digestive health and reduced risk of certain diseases such as heart disease, type 2 diabetes, and certain types of cancer. So therefore the correct answer is 1) higher in dietary fiber than an omnivorous diet.
