00:00With over 1.8 billion bottles of Coca Cola sold a day
00:04and nearly half of Americans drinking at least one glass of soda or pop a day.
00:08it's safe to say that many of us love a sugary drink.
00:11But what would happen to our brains and bodies if we only drank soda?
00:16As the drink enters your mouth.
00:17It's high acid content begins to erode the enamel on your teeth.
00:21And the microorganisms in your plaque start to feed off the sugar which can lead to cavities.
00:26Finish the can and you may have consumed upwards of 46 grams of sugar.
00:31The receptors on your tongue sense this
00:32and send a message to your cerebral cortex.
00:35Activating the rewards center of the brain, which says "More, please!"
00:39After a week of substituting the recommended daily 8 glasses of water for cola instead,
00:44You would have consumed around 5432 extra calories.
00:50And this is one of the biggest health problems linked to carbonated drinks.
00:54Weight gain.
00:55It's been estimated that 1/5 of the weight gain in the U.S. between 1977 and 2007 can be attributed to soft drinks.
01:04Furthermore Yale researchers found that when people drink soft drinks,
01:07they also consume more calories,
01:10mainly because people don't accurately account for the added calories in their beverage.
01:14On top of this, the high fructose corn syrup, which is the primary soda sweetener.
01:18is not metabolized in our bodies the same way other sugars are.
01:22They increase liver fat upping the risk of cardiovascular disease.
01:26And don't stop stimulate the hormones Insulin and Leptin
01:29these hormones help the body signal when we're full to prevent overeating.
01:32The disruption of Insulin also increases the risk of diabetes.
01:36Overall research suggests that reducing the amount of sugar in drinks,
01:40could prevent 1 million cases of obesity.
01:43So should we swap in diet drinks instead?
01:45Surprisingly there's still a link between artificial sweeteners and weight gain as well.
01:50Experiments have found that the sweet taste, whether from real sugar or artificial sweeteners, enhances our appetite.
01:57not to mention many diet drinkers allow themselves to eat more.
02:00Because they believe they've already reduced their calories
02:03thinking, "I'm having a diet soda so I can have a large fry with my burger"
02:07But soft drinks can also age us.
02:10Telomeres are protective caps on the end of our chromosomes, which shortened overtime.
02:15And it turns out that their rate of shortening is nearly the same
02:18in a person who drinks six hundred milliliters of soda a day as it is in a smoker.
02:22So what if you drank two liters of pop every day?
02:26Well, one woman did just that for sixteen years straight
02:30until she was hospitalized at age 31 with no family history of heart problems
02:35she suffered from arrhythmia and fainting spells.
02:38And tests found her severely deficient in potassium
02:41as both fructose and caffeine can lead to potassium loss through urine and diarrhea.
02:46Luckily our bodies have an amazing ability to recover
02:49and once she quit, her potassium levels and other complications began to rebound.
