A healthy lifestyle offers many benefits, including helping to prevent heart disease, type 2 diabetes, obesity, and other chronic diseases. Another important benefit is that healthy routines enhance your immunity. The immune system is the body’s way of protecting itself from infection and disease; it fights everything from cold and flu viruses to serious conditions such as cancer. Our immune systems are complex and influenced by many factors. Vaccines build immunity against specific diseases. Some additional ways you can strengthen your immune system are eating well, being physically active, maintaining a healthy weight, getting enough sleep, not smoking, and avoiding excessive alcohol use.

Avoid Too Much Alcohol

What drug was originally in Pepsi?

Pepsi-Cola: Known for medicinal properties Indeed, the name Pepsi-Cola, introduced in 1898, implies its origin as a health tonic: “Pepsi” is taken from pepsin, a digestive enzyme used in Bradham's original formula. Just as Coca-Cola no longer contains cocaine, Pepsi no longer includes pepsin.

Dr Pepper: A strange name

Was there a doctor involved in the creation of Dr Pepper? No, but there was yet another pharmacist who, while not actually named Pepper (his name was Charles Alderton), invented the drink in Waco, Texas, in 1885. And if you’re guessing that “Dr Pepper’s Phos-Ferrates” was originally touted as a health tonic, just like Coke and Pepsi, you’d be correct in that as well. One ingredient in Dr Pepper’s early formulas was pepsin, the same digestive enzyme that gave Pepsi its name. (However, prune juice, commonly rumored to be an ingredient, is not and never was part of the formula.) Interestingly, no one, including the folks at Dr Pepper or the Dr Pepper Museum in Waco, knows exactly how the soda pop got its name; theories range from a nod to pepsin to the soda being named in honor of the former owner of the drugstore where the drink was invented. None of these theories is verified. (And for you editorial types, there is no period after the “Dr” in “Dr Pepper”; it was removed sometime in the 1950s.)
