Most people believe that all carbs are the foods that make you put on weight or get fat which is completely wrong, generally those carbs people are referring to are synthetic or a hybrid of plants such as wheat or malt which are not a natural form of carbohydrates. Carbohydrates are molecules containing carbon, hydrogen, and oxygen which are then broken down to small molecules call glucose which is the main food source that are body needs, as EVERY SYSTEM IN OUR BODY runs on glucose and any glucose that is not used is transferred into glycogen and stored in the liver and muscle. So a diet absent of carbs will cause some people to feel tired or sick.
These carbohydrates that people refer to are generally acidic and high in starch which are low in oxygen and when these carbohydrates are not used they begin to clog the body and the starch from the acidic carbohydrates begin to cause mucus to build up causing diseases due to lack of oxygen.
Spelt is a grain which is a more alkaline based which can be used to make spelt pasta,spelt bread pizza bases and bagels etc is a form of alternative carbohydrate so avoiding carbohydrates is not something that has to be done, its avoiding the wrong carbohydrates which must be done. I will talk about more alternative carbohydrates as well as more delicious recipes later.
