hours after gastric emptying, and it 'oxygen to the muscles being subtracted.
Both the gastric emptying time that digestion can be shortened favoring carbohydrates (fruit, pasta, rice) compared to protein and fat reducing the amount 'minimum essential; must be avoided even vegetables and salads perche'il their fiber content slows digestion.

-the speed 'of gastric emptying is slowed by the need' to be part of the stomach to fractionate morsels solid parts in the most 'can small or close to the liquid state, so that if the carbohydrates are preferred for this' and' true for most forms 'easily divisible (eg rice and pasta rather than rolls, also because' starches cooked in water are reduced to fragments more 'simple)
