It’s best to save sports drinks for when you’re exercising vigorously and/or you need to replenish your body’s reserves of carbs, salts, and water because you’re exercising very hard for a very long time or when it is hot outside (see here).
LIMIT! DRINKS WITH ADDED SUGAR
Drinks sweetened with added sugar, like soda, “juice drinks,” fruit-flavored drinks, fruit punch, fruitades, and sweetened teas are also fluidsbut these should be drunk only occasionally Don’t be lured into choosing large or supersize drinksall for a few cents more. Who needs that amount of sugar?
The high energy content (calorie content) of these drinks isn’t accompanied by many nutrients. Drinking (and eating) too many energy-dense, nutrient-poor fluids (or foods) isn’t a good direction to go in.
The king-size soda sold at movies is 32 ouncescontaining 27 teaspoons of sugar! See here.
