Research shows: This popular beverage can destroy your eyesight

For years, diet soda has been portrayed as a healthier alternative to regular soda, especially for diabetics. But nothing could be further from the truth.

In fact, in his Ageless Vision Protocol, Dr. Fred Pescatore reveals research showing that drinking soda isn’t just bad for your overall metabolic health, it also raises the risk of proliferative diabetic retinopathy—a serious eye disease that can leave diabetics blind.

Proliferative diabetic retinopathy damages the blood vessels in the retina—that’s the nerve tissue at the back of your eye that transmits visual images to your brain.

Here’s how Dr. Pescatore explains it: “This damage is caused by out-of-control blood sugar and inflammation—damage that negatively affects the tiny blood vessels that supply the retina. Eventually, this damage causes bleeding and scarring. And it’s this scar tissue that threatens your eyesight.”

And here’s the really scary part: It doesn’t take a lot of diet soda to increase the risk of this vision-robbing disease.

Dr. Pescatore cites a study that examined more than 600 patients with type 1 or type 2 diabetes. Results showed that—compared with adults who never drank diet soda—those who drank more than 4 cans per week were a shocking 2.5 times more likely to develop diabetic retinopathy!

In other words, less than a single diet soda per day could do permanent harm to your eyesight.

Not to mention, past research has linked diet soda to a higher risk of metabolic syndrome, heart disease and type 2 diabetes.

In Dr. Pescatore’s view, he’s seen enough of the ever-growing mountain of evidence that suggests that artificially sweetened soft drinks are just as dangerous as the sugar-sweetened variety.

“Can we all just ditch all diet soft drinks now?” he asks. “Because this research really is just the tip of the iceberg.

As for a healthy substitute, Dr. Pescatore asks, “What’s wrong with water?”

He says, “You can jazz things up with lemon, mint, a couple of fresh berries, or cucumbers. And if regular old tap water isn’t exciting enough for you, there’s always sparkling mineral water, decaf coffee, or herbal tea.”

In fact, a comforting cup of tea provides an added benefit for your eyes. Dr. Pescatore cites a study that linked drinking hot tea to an impressive 74 percent reduction in glaucoma risk.

And you don’t have to drink your coffee or tea without a sweetener.

Dr. Pescatore points to the one sweetener that gets his approval: Stevia. He notes that you can add this safe, all-natural, non-nutritive sweetener to any beverage. He recommends the Sweet Leaf brand.

“So today,” Dr. Pescatore says, “I challenge you to rid your home of any and all diet beverages (and it should go without saying, but all regular soda too). The health benefits you’ll reap far outweigh the inconvenience of cutting it out of your diet.”
