You should always take the precaution of waiting between three or four hours, to go from food to physical training, since for example jogging with a full stomach can damage your digestion, causing reactions such as nausea and diarrhea, which are risks more common.
Doctors recommend having a small snack before a workout, such as some bread, with cheese spread or a banana that is not too ripe, it is even better, since it maintains blood sugar levels, for its content in starch and glucose easily digestion.
In addition, the fructose or lactose content in food can sometimes lead to stomach problems, say specialists in nutrition.
As well as the excesses of fiber in the diet tend to bloating, which should be avoided being a suitable example consuming a banana whose fiber content is low, for example.
For after training if you want to eat, the ideal is to do it within the first hour or two, after the practice, because that is the best time to assimilate the nutrients. (Information from the German Institute for Health Prevention and Management).
