Coconut oil has many uses for cooking. It is a great substitute for butter, it can be used in baking, and it can provide a flavorful finish to dishes that are typically cooked with other oils. However, in some cases, substituting coconut oil is not optimal or even beneficial. The following are some of the reasons why coconut oil substitutes should be used in granola bars:1. Some people have an allergy to coconut oil, which means they cannot eat it. Coconut oil substitutes can be used in place of the coconut oil to avoid allergic reactions.2. Some people do not like the taste and texture of coconut oil, so they prefer a different type of fat or liquid to use as a substitute in recipes. Coconut oil substitutes include olive oil, safflower oil, avocado oil, and almond milk (for those who are lactose intolerant).3. Coconut oil does not have all of the nutrients that are found in natural fats such as milk and cream; therefore, using it as a substitute for these ingredients may result in less nutritional value for your body.
