Are you getting all the micro-nutrients that your body requires?
Foods that are nutrient rich, contain a lot of vitamins and minerals but are low in calories. Nutrient dense foods are also low in sugar, sodium, starches, and bad saturated fats. To nourish the body effectively it is best to choose a mix of nutrient dense foods everyday, containing vitamins, lean proteins, minerals, healthy fats (Omega-3 fat), and complex carbohydrates. Naturally nutrient rich foods are fruits and vegetables, lean meats, fish (the ultimate brain food), whole grains, eggs, dairy, legumes, nuts and seeds, which all help in keeping your body and brain nourished and healthy.
Working out before breakfast may be more beneficial for health than eating first.
