4 Foods and Drinks That Contain Caffeine and Aren't Coffee

According to a study conducted by the government regulatory agency Health Canada, 400 milligrams of caffeine daily is considered safe to healthy adults. 

"Clinical recommendations advising against the regular consumption of caffeinated products to prevent disturbances of the heart's cardiac rhythm should be reconsidered, as we may unnecessarily be discouraging consumption of items like chocolate, coffee and tea that might actually have cardiovascular benefits," Dr. Gregory Marcus, a researcher from the University of California at San Francisco, told the Daily Mail. "Given our recent work demonstrating that extra heartbeats can be dangerous, this finding is especially relevant."

Arizona Energy Drinks 

A 11.5 oz. can of Arizona Caution Extreme Performance can contain 144 mg of caffeine, while a 16 oz. Arizona Green Tea Energy may contain up to 200 milligrams, regardless of the type purchased — the pomegranate flavor and diet version all contain high levels of caffeine, according to the Caffeine Informer website.

The Green Tea drink, without the "energy," contains 7.5 mg of caffeine per ounce serving.

Vitamin Water Energy 

An outgrowth of the popular Vitamin Water beverage, VitaminWater Energy Drink contains 80 milligrams of caffeine, a moderate amount, according to Caffeine Informer. The caffeine in Vitamin Water's energy drink stems from a green coffee bean extract, cane sugar and stevia, an FDA-approved sweetener. 

Dark Chocolate

Dark chocolate contains caffeine, but generally not enough for healthy persons to be concerned with, manufacturing company Amano Chocolate states. 

"So does chocolate contain caffeine? The answer is yes," the website reads. "Does chocolate contain lots of caffeine? The answer is no. Chocolate has been found to contain enough caffeine to be of concern to people with heart or other ailments." 

According to the United States Department of Agriculture, one bar (162 g) can contain 70 mg of caffeine. 

Sumseeds 

Sumseeds, roasted sunflower seeds that have caffeine and taurine as ingredients, contain 120 mg per 3.5 oz bag, according to Caffeine Informer

"Each 3.5oz bag of premium, gum-toughening seeds is dusted with 120mg of caffeine -- one-and-a-half times the amount in the energy drinks favored by thrill junkies and rehabbing celebrities worldwide," Thrillist reported. "And unlike liquid-based energy delivery systems, Sumseeds won't have you constantly waiting for the bathroom, unless the crapper's where you plan to dispose of two cheeks full of slobbery shells."
