1. Probiotic-Rich Foods
The human body carries over 100 million bacteria in the gut, these bacteria work synergistically with the body to contribute to the synthesis of vitamins and neurotransmitters. The connection between the brain and gut is bidirectional which means that if one contains a high processed meal that is loaded with simple sugars the brain will suffer from a lack of neurotransmitters and vital nutrients. Sauerkraut, kimchee and kefir are all good food choices, you can also supplement probiotics.
75 percent of the processes that take place in the brain are om the presence of water, drinking an adequate amount of water will help increase concentration and mental clarity, while helping to remove toxins and waste from the bloodstream. An easy way to calculate your water requirement is taking half of your body weight in lbs and drinking the equivalent in ounces of water.
Cocoa flavonoids have been proven to improve blood flow to the brain meaning it is receiving more nutrients and oxygen. You can either opt for a chocolate bar that has 75% or more cocoa content or you can get yourself some cocoa powder to add to smoothies.
