Brown rice
Brown rice is a very nutritious food. Unlike white rice, it is less processed and retains more nutritional value in the form of fiber, vitamins and minerals. It provides about 88% of the RDI for manganese, a mineral that helps your enzymes break down carbohydrates and proteins to generate energy.
Goji berries
Besides being packed with antioxidants, vitamins and minerals, this fruit is known to be a good source of fiber. Research has suggested that goji berry juice could provide antioxidant protection, assist with mental performance and alertness, and help decrease feelings of fatigue. Eat them with yogurt or raw.
