Milk makeslots of mass fart . Drinkingraw milkis like play Russian roulette with serious stomach issues , and moo juice may not on the dot be thecalcium - packed powerhousethe dairy manufacture would like you to believe . But the one thing milk is astonishingly good at , other than being the opt liquid to dip cookies in , is rehydrating your soundbox .

At least , that ’s grant to a new study that also claims cola and orange juice are more hydrating than water . Clearly , researchers overrode their common sense , and instead just quantify how good certain drinkable are at rehydrating your torso based on how much people had to pee after pledge them . If you pee less oft but are eat up the same water content , the assumption goes , you ’re drink a hydrating drink .

What the hell is this hydration index?

Researchers wanted to find out how much water your body absorb from various drinks , based on several factors : how many carbs and electrolytes are in each boozing , the sodium capacity , and if there ’s a diuretic present tense .

The hydration indicant essay to hearten with liquids what theglycemic indexdoes for food for thought , but somewhere along the room the ranking ends up claiming beer is basically on par with sports drinks at refill lost fluid . Which is entirely fine !

researcher also looked at how much each person peed after drink each potable , and compared it to the still water control chemical group . Full - fat Milk River , for model , created less water than water did in participants , but burnt umber produced more – not disgraceful to anyone who ’s had to sit down in traffic after chugging a venti iced coffee berry .

By the study ’s standards , less urine equated to more hydration . To put it into chart form , researcher divided the amount of piddle clear after drinking the still water , by the pee pass by after each mental test beverage , creating a " beverage hydration index , " or BHI . A high-pitched BHI have in mind more water is keep back in the physical structure than if the toper had consume an adequate volume of still water system . They also left a margin of misplay to include the water supply content of each beverage ( body of water obviously has more water content than coffee tree does , for representative ) , but that did n’t seem to make much of a difference .

The upshot ? According to this ranking , skim milk is the most hydrating beverage on the block .

Should I be chugging milk after every workout?

Though this higher-ranking points to skim Milk River as the most hydrating drink , do n’t bulge out stocking up on the fat - free stuff and nonsense just yet . First of all , milk after a workout is gross . Also , whole milkprovides more vitamins and nutrients , and about 65 % of the great unwashed ca n’t digest dairy farm .

Finally , since the forefinger claims cola is more hydrating than water , this probably serve as a skillful reminder that even a subject area with straightforward methods and no hidden agenda can be deep blemished . For yourpost - workout refuel , it ’s best to apply common sense and stick to the test - and - genuine method of unpatterned water . If you ’re a serious athlete or grooming for a endurance contest , meaning you ’re exercising intensely for two or more hours straight , then it ’s fine to hand for your favorite sports drink .

But if you ’re feel a piddling superfluous thirsty , or looking for something that wo n’t make you lead to the restroom ASAP , maybe Ron Burgundy was wrong after all ; milk ’s really not a bad choice .
