Juice contains mostly fructose and water, and is rapidly absorbed requiring minimal digestion, thus providing quick energy for a perk. Both citrus juices and cocoa-based drinks are rich in flavonoids, which may increase cerebral blood flow and increase neural activity.2
So what’s wrong with a typical bowl of corn flakes to go with a cup of juice, cocoa or tea? Refined grains fall flat of providing sustained energy. For that you’ll need complex carbohydrates and a little protein and healthy (unsaturated) fat. One type of complex carbohydrate, known as fructo-oligosaccharides, may boost mood by way of its effect on gut bacteria which influences behavior via neurotransmitter systems. Another type, inulin, is similar to fructo-oligosaccharides and linked to improvements in learning and memory tasks, such as accuracy in recall.3 Some lean protein and healthy fat serve to prolong the energy from carbohydrates.
