Starch, also known as farina, is contained in bread, pasta, cereals, potatoes (starchy veggies), legumes (beans, peas, rice, lentil) and others.
I do recommend you that you eat no later than 17-18 PM since the later you eat, the worse the digestion and stomach functions are. We need to provide enough time for the body to digest the food properly. That way, we will wake up strong and fresh as daisies every morning.
Some foods are digested quite quickly unlike many others. Fruits, for instance, are pretty fast to digest (that takes only an hour after their consumption) since they go directly into the small intestine. The reason is that they contain ferments which boost the assimilation.
