Caffeinated



Kerry Coyne:

We have watched the coffee category expand and adapt as Millennials converted to coffee drinkers, attracted by the smoother flavor and artisanal characteristics and third - and fourth-wave coffee, we knew our culinary team could deliver that same premium, hand-crafted sensory experience with the bellowed category hero of espresso in our best-in-class, fresh-baked bagel. The caffeine in the bagel is sourced from both espresso and coffee-cherry flour. Einstein’s exact recipe is proprietary but in addition to packing a caffeinated punch, the new bagel also has 13 grams of protein, derived from cocoa. We ’d all love a little extra energy in the morning, but do the enhancned bagels actually taste any good ? The product left tasters divided in a pretty even split. The product itself resembles a dark brown pumpernickel bagel and, upon the first few nibbles, tastes like a chewy plain bagel with a slightly sweet taste. After a few more bites, however, the bitterness from the espresso really kicks in.

INTRODUCTION

Caffeinated coffee and tea are the most consumed, socially accepted stimulants in the world. Approximately 90 percent of all adults in the world consume caffeine daily. In their natural forms, coffee and tea contain several chemical components that may confer both beneficial and adverse health effects, including caffeine and antioxidants (eg, polyphenols, catechins, and flavonoids).

Most of the data on the health benefits and risks of caffeine are from observational studies in which self-reported consumption of beverages and foods is associated with health outcomes. Such studies make it difficult to identify caffeine itself as the causative agent and to exclude residual confounding. Based on available data, there is insufficient evidence for promoting or discouraging regular coffee and/or tea consumption. Caffeine has multiple systemic effects on the neuropsychiatric, cardiovascular, endocrine, and gastrointestinal systems. The impact on health may be modified by genetic factors, age, sex, medications, and other environmental exposures.

Caffeinated Drinks

This review will focus on the effects of caffeine and caffeinated beverages on specific disease processes, including insulin resistance, cancer, and all-cause mortality. The specific effects of caffeine on the cardiovascular system, as well as the effects of caffeine on pregnancy, are discussed separately. (See 'Cardiovascular effects of caffeine and caffeinated beverages' and 'Nutrition in pregnancy'.)

CONSUMPTION

Safe levelsFor most adults, consumption of up to 400 mg of caffeine a day appears to be safe [1-3]. A list of commonly consumed caffeinated beverages and average caffeine content is shown in the table (table 1).

Limited data are available about safe levels of caffeine consumption in children and adolescents. A systematic review found that intake of 2.5 mg caffeine/kg of body weight per day is not associated with adverse effects [3]. Young adults need to be cautioned about using caffeinated energy drinks in excess and not mixing them with other substances. (See 'Dependence and abuse' below.)
