Sports dietitians have recommended runners pregame a workout, long run, or race by eating Rice Krispie treats or Uncrustables, and often tout consuming sports drinks, gummies, and gels midrun. The problem: These are all technically ultraprocessed foods, which dietitians also suggest you limit as much as possible.
“With athletes, convenience and accessibility are important, and processed foods should play a role in their training.”Sure, you could eat a peanut butter sandwich made with minimally processed foods to fill your energy bucket, but imagine running with a sack of them or even a few bananas.“Depending on the intensity and length of your training, you need about 30 to 60 grams of carbohydrates per hour,” Link says.
