Can an athlete get all their nutritional requirements from food?
Yes, this is certainly possible. An athlete is more likely to achieve this by eating a diet that is balanced (and does not cut out food groups) and by being organised. Relying on convenience foods or skipping meals and snacks will make it more difficult to meet nutritional requirements.
Yes, provided they eat a well-balanced diet including all the different food groups (fruit and vegetables, dairy, meat and/or meat alternatives, starches and healthy fats) and match their energy intake with their training load (i.e. provided they eat enough food for the amount of exercise they do).
The single most important dietary component in any athletes’ diet is their energy intake. Energy can be obtained from various nutrients that are embedded in the food we eat. It makes sense than that, if an athlete eats MORE food, but also includes a VARIETY of food sources from all the different food groups; he/she can totally fulfil all their nutritional requirements through a balanced, varied diet.
